AwsEcsTaskDefinitionProperties

Name	Description	Value
containerDefinitions	A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.	ContainerDefinition[]
cpu	The number of cpu units used by the task. If you use the EC2 launch type, this field is optional. Any value can be used. If you use the Fargate launch type, this field is required. You must use one of the following values. The value that you choose determines your range of valid values for the memory parameter. The CPU units cannot be less than 1 vCPU when you use Windows containers on Fargate. + 256 (.25 vCPU) - Available memory values: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) + 512 (.5 vCPU) - Available memory values: 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) + 1024 (1 vCPU) - Available memory values: 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) + 2048 (2 vCPU) - Available memory values: 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) + 4096 (4 vCPU) - Available memory values: 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) + 8192 (8 vCPU) - Available memory values: 16 GB and 60 GB in 4 GB increments This option requires Linux platform 1.4.0 or later. + 16384 (16vCPU) - Available memory values: 32GB and 120 GB in 8 GB increments This option requires Linux platform 1.4.0 or later.	string
ephemeralStorage	The ephemeral storage settings to use for tasks run with the task definition. The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on FARGATElong. For more information, see Using data volumes in tasks in the Amazon ECS Developer Guide;. For tasks using the Fargate launch type, the task requires the following platforms: + Linux platform version 1.4.0 or later. + Windows platform version 1.0.0 or later.	EphemeralStorage
executionRoleArn	The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make AWS API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide.	string
family	The name of a family that this task definition is registered to. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add. To use revision numbers when you update a task definition, specify this property. If you don't specify a value, CFNlong generates a new task definition each time that you update it.	string
inferenceAccelerators	The Elastic Inference accelerators to use for the containers in the task.	InferenceAccelerator[]
ipcMode	The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference. If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security. If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide. + For tasks that use the host IPC mode, IPC namespace related systemControls are not supported. + For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task. This parameter is not supported for Windows containers or tasks run on FARGATElong.	string
memory	The amount (in MiB) of memory used by the task. If your tasks runs on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified, the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition. If your tasks runs on FARGATElong, this field is required. You must use one of the following values. The value you choose determines your range of valid values for the cpu parameter. + 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU) + 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU) + 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU) + Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available cpu values: 2048 (2 vCPU) + Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available cpu values: 4096 (4 vCPU) + Between 16 GB and 60 GB in 4 GB increments - Available cpu values: 8192 (8 vCPU) This option requires Linux platform 1.4.0 or later. + Between 32GB and 120 GB in 8 GB increments - Available cpu values: 16384 (16 vCPU) This option requires Linux platform 1.4.0 or later.	string
networkMode	The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. If no network mode is specified, the default is bridge. For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode. With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings. When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user. If the network mode is awsvpc, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide. If the network mode is host, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used. For more information, see Network settings in the Docker run reference.	string
pidMode	The process namespace to use for the containers in the task. The valid values are host or task. On Fargate for Linux containers, the only valid value is task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task. If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same process namespace. If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference. If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security. This parameter is not supported for Windows containers. This parameter is only supported for tasks that are hosted on FARGATElong if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.	string
placementConstraints	An array of placement constraint objects to use for tasks. This parameter isn't supported for tasks run on FARGATElong.	TaskDefinitionPlacementConstraint[]
proxyConfiguration	The configuration details for the App Mesh proxy. Your Amazon ECS container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS optimized AMI version 20190301 or later, they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. The configuration details for the App Mesh proxy. For tasks that use the EC2 launch type, the container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS optimized AMI version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI	ProxyConfiguration
requiresCompatibilities	The task launch types the task definition was validated against. The valid values are EC2, FARGATE, and EXTERNAL. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.	string[]
runtimePlatform	The operating system that your tasks definitions run on. A platform family is specified only for tasks using the Fargate launch type. When you specify a task definition in a service, this value must match the runtimePlatform value of the service. Information about the platform for the Amazon ECS service or task. For more information about RuntimePlatform, see RuntimePlatform in the Amazon Elastic Container Service Developer Guide.	RuntimePlatform
tags	The metadata that you apply to the task definition to help you categorize and organize them. Each tag consists of a key and an optional value. You define both of them. The following basic restrictions apply to tags: + Maximum number of tags per resource - 50 + For each resource, each tag key must be unique, and each tag key can have only one value. + Maximum key length - 128 Unicode characters in UTF-8 + Maximum value length - 256 Unicode characters in UTF-8 + If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @. + Tag keys and values are case-sensitive. + Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for AWS use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.	TagAutoGenerated27[]
taskDefinitionArn	Property taskDefinitionArn	string
taskRoleArn	The short name or full Amazon Resource Name (ARN) of the IAMlong role that grants containers in the task permission to call AWS APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide. IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code to use the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide.	string
volumes	The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide. The host and sourcePath parameters aren't supported for tasks run on FARGATElong.	Volume[]

ContainerDefinition

Name	Description	Value
command	The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd. If there are multiple arguments, each argument is a separated string in the array.	string[]
cpu	The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value. You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024. Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units. On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version: + Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares. + Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2. On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0, which Windows interprets as 1% of one CPU.	int
credentialSpecs	A list of ARNs in SSM or Amazon S3 to a credential spec (CredSpec) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions. The maximum number of ARNs is 1. There are two formats for each ARN. + credentialspecdomainless:MyARN You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in . You provide the login credentials to the domain in the secret. Each task that runs on any container instance can join different domains. You can use this format without joining the container instance to a domain. + credentialspec:MyARN You use credentialspec:MyARN to provide a CredSpec for a single domain. You must join the container instance to the domain before you start any tasks that use this task definition. In both formats, replace MyARN with the ARN in SSM or Amazon S3. If you provide a credentialspecdomainless:MyARN, the credspec must provide a ARN in ASMlong for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.	string[]
dependsOn	The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed. For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. For tasks using the Fargate launch type, the task or service requires the following platforms: + Linux platform version 1.3.0 or later. + Windows platform version 1.0.0 or later. If the task definition is used in a blue/green deployment that uses AWS::CodeDeploy::DeploymentGroup BlueGreenDeploymentConfiguration, the dependsOn parameter is not supported. For more information see Issue #680 on the on the GitHub website.	ContainerDependency[]
disableNetworking	When this parameter is true, networking is off within the container. This parameter maps to NetworkDisabled in the Create a container section of the Docker Remote API. This parameter is not supported for Windows containers.	bool
dnsSearchDomains	A list of DNS search domains that are presented to the container. This parameter maps to DnsSearch in the Create a container section of the Docker Remote API and the --dns-search option to docker run. This parameter is not supported for Windows containers.	string[]
dnsServers	A list of DNS servers that are presented to the container. This parameter maps to Dns in the Create a container section of the Docker Remote API and the --dns option to docker run. This parameter is not supported for Windows containers.	string[]
dockerLabels	A key/value map of labels to add to the container. This parameter maps to Labels in the Create a container section of the Docker Remote API and the --label option to docker run. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'	any
dockerSecurityOptions	A list of strings to provide custom configuration for multiple security systems. For more information about valid values, see Docker Run Security Configuration. This field isn't valid for containers in tasks using the Fargate launch type. For Linux tasks on EC2, this parameter can be used to reference custom labels for SELinux and AppArmor multi-level security systems. For any tasks on EC2, this parameter can be used to reference a credential spec file that configures a container for Active Directory authentication. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers in the Amazon Elastic Container Service Developer Guide. This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API and the --security-opt option to docker run. The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide. For more information about valid values, see Docker Run Security Configuration. Valid values: 'no-new-privileges' | 'apparmor:PROFILE' | 'label:value' | 'credentialspec:CredentialSpecFilePath'	string[]
entryPoint	Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint, update your container agent or enter your commands and arguments as command array items instead. The entry point that's passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint.	string[]
environment	The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run. We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.	KeyValuePair[]
environmentFiles	A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run. You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored. For more information about the environment variable file syntax, see Declare default environment variables in file. If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.	EnvironmentFile[]
essential	If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential. All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.	bool
extraHosts	A list of hostnames and IP address mappings to append to the /etc/hosts file on the container. This parameter maps to ExtraHosts in the Create a container section of the Docker Remote API and the --add-host option to docker run. This parameter isn't supported for Windows containers or tasks that use the awsvpc network mode.	HostEntry[]
firelensConfiguration	The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide. The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom log routing in the Amazon Elastic Container Service Developer Guide.	FirelensConfiguration
healthCheck	The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run. The HealthCheck property specifies an object representing a container health check. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image (such as those specified in a parent image or from the image's Dockerfile). This configuration maps to the HEALTHCHECK parameter of docker run. The Amazon ECS container agent only monitors and reports on the health checks specified in the task definition. Amazon ECS does not monitor Docker health checks that are embedded in a container image and not specified in the container definition. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image. If a task is run manually, and not as part of a service, the task will continue its lifecycle regardless of its health status. For tasks that are part of a service, if the task reports as unhealthy then the task will be stopped and the service scheduler will replace it. The following are notes about container health check support: + Container health checks require version 1.17.0 or greater of the Amazon ECS container agent. For more information, see Updating the Amazon ECS Container Agent. + Container health checks are supported for Fargate tasks if you are using platform version 1.1.0 or greater. For more information, see Platform Versions. + Container health checks are not supported for tasks that are part of a service that is configured to use a Classic Load Balancer.	HealthCheck
hostname	The hostname to use for your container. This parameter maps to Hostname in the Create a container section of the Docker Remote API and the --hostname option to docker run. The hostname parameter is not supported if you're using the awsvpc network mode.	string
image	The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest. Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run. + When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks. + Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest. For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE. + Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo). + Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent). + Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu).	string
interactive	When this parameter is true, you can deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the Create a container section of the Docker Remote API and the --interactive option to docker run.	bool
links	The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run. This parameter is not supported for Windows containers. Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.	string[]
linuxParameters	Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities. This parameter is not supported for Windows containers. The Linux-specific options that are applied to the container, such as Linux KernelCapabilities.	LinuxParameters
logConfiguration	The log configuration specification for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However, the container may use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation. Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}' The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide. The LogConfiguration property specifies log configuration options to send to a custom log driver for the container.	LogConfiguration
memory	The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. If using the Fargate launch type, this parameter is optional. If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used. The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container, so you should not specify fewer than 6 MiB of memory for your containers. The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.	int
memoryReservation	The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run. If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used. For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed. The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers. The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.	int
mountPoints	The mount points for data volumes in your container. This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run. Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives.	MountPoint[]
name	The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run.	string
portMappings	The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic. For task definitions that use the awsvpc network mode, you should only specify the containerPort. The hostPort can be left blank or it must be the same value as the containerPort. Port mappings on Windows use the NetNAT gateway address rather than localhost. There is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself. This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to none, then you can't specify port mappings. If the network mode of a task definition is set to host, then host ports must either be undefined or they must match the container port in the port mapping. After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.	PortMapping[]
privileged	When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run. This parameter is not supported for Windows containers or tasks run on FARGATElong.	bool
pseudoTerminal	When this parameter is true, a TTY is allocated. This parameter maps to Tty in the Create a container section of the Docker Remote API and the --tty option to docker run.	bool
readonlyRootFilesystem	When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the Create a container section of the Docker Remote API and the --read-only option to docker run. This parameter is not supported for Windows containers.	bool
repositoryCredentials	The private repository authentication credentials to use. The repository credentials for private registry authentication.	RepositoryCredentials
resourceRequirements	The type and amount of a resource to assign to a container. The only supported resource is a GPU.	ResourceRequirement[]
secrets	The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.	Secret[]
startTimeout	Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE, SUCCESS, or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state. When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value. For tasks using the Fargate launch type, the task or service requires the following platforms: + Linux platform version 1.3.0 or later. + Windows platform version 1.0.0 or later. For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. The valid values are 2-120 seconds.	int
stopTimeout	Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own. For tasks using the Fargate launch type, the task or service requires the following platforms: + Linux platform version 1.3.0 or later. + Windows platform version 1.0.0 or later. The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used. For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. The valid values are 2-120 seconds.	int
systemControls	A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.	SystemControl[]
ulimits	A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}' This parameter is not supported for Windows containers.	Ulimit[]
user	The user to use inside the container. This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run. When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security. You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer. + user + user:group + uid + uid:gid + user:gid + uid:group This parameter is not supported for Windows containers.	string
volumesFrom	Data volumes to mount from another container. This parameter maps to VolumesFrom in the Create a container section of the Docker Remote API and the --volumes-from option to docker run.	VolumeFrom[]
workingDirectory	The working directory to run commands inside the container in. This parameter maps to WorkingDir in the Create a container section of the Docker Remote API and the --workdir option to docker run.	string

It validates that a dependent container is started before permitting other containers to start. + COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container. + SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container. + HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.	string

filesystemId	The Amazon EFS file system ID to use.	string
rootDirectory	The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter. If an EFS access point is specified in the authorizationConfig, the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.	string
transitEncryption	Determines whether to use encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be turned on if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide.	'DISABLED' 'ENABLED'
transitEncryptionPort	The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server.

HostVolumeProperties

Name	Description	Value
sourcePath	When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported. If you're using the Fargate launch type, the sourcePath parameter is not supported.	string

name	The name of the key-value pair. For environment variables, this is the name of the environment variable.	string
value	The value of the key-value pair. For environment variables, this is the value of the environment variable.	string

LinuxParameters

Name	Description	Value
capabilities	The Linux capabilities for the container that are added to or dropped from the default configuration provided by Docker. For tasks that use the Fargate launch type, capabilities is supported for all platform versions but the add parameter is only supported if using platform version 1.4.0 or later. The Linux capabilities to add or remove from the default Docker configuration for a container defined in the task definition. For more information about the default capabilities and the non-default available capabilities, see Runtime privilege and Linux capabilities in the Docker run reference. For more detailed information about these Linux capabilities, see the capabilities(7) Linux manual page.	KernelCapabilities
devices	Any host devices to expose to the container. This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run. If you're using tasks that use the Fargate launch type, the devices parameter isn't supported.	Device[]
initProcessEnabled	Run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'	bool
maxSwap	The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value. If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used. If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.	int
sharedMemorySize	The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run. If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.	int
swappiness	This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100. If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run. If you're using tasks that use the Fargate launch type, the swappiness parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.	int
tmpfs	The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run. If you're using tasks that use the Fargate launch type, the tmpfs parameter isn't supported.	Tmpfs[]

LogConfiguration

Name	Description	Value
logDriver	The log driver to use for the container. For tasks on FARGATElong, the supported log drivers are awslogs, splunk, and awsfirelens. For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries,syslog, splunk, and awsfirelens. For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide. For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide. If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.	string
options	The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'	any
secretOptions	The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide.	Secret[]

MountPoint

Name	Description	Value
containerPath	The path on the container to mount the host volume at.	string
readOnly	If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.	bool
sourceVolume	The name of the volume to mount. Must be a volume name referenced in the name parameter of task definition volume.	string

PortMapping

Name	Description	Value
appProtocol	The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch. If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP. appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment. Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.	'grpc' 'http' 'http2'
containerPort	The port number on the container that's bound to the user-specified or automatically assigned host port. If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort. If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.	int
containerPortRange	The port number range on the container that's bound to the dynamically mapped host port range. The following rules apply when you specify a containerPortRange: + You must use either the bridge network mode or the awsvpc network mode. + This parameter is available for both the EC2 and FARGATElong launch types. + This parameter is available for both the Linux and Windows operating systems. + The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package + You can specify a maximum of 100 port ranges per container. + You do not specify a hostPortRange. The value of the hostPortRange is set as follows: + For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange. This is a static mapping strategy. + For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports. + The containerPortRange valid values are between 1 and 65535. + A port can only be included in one port mapping per container. + You cannot specify overlapping port ranges. + The first port in the range must be less than last port in the range. + Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide. You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.	string
hostPort	The port number on the container instance to reserve for your container. If you specify a containerPortRange, leave this field empty and the value of the hostPort is set as follows: + For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort. This is a static mapping strategy. + For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy. If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort. If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version. The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range. The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.	int
name	The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.	string
protocol	The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp. protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.	string

ProxyConfiguration

Name	Description	Value
containerName	The name of the container that will serve as the App Mesh proxy.	string
proxyConfigurationProperties	The set of network configuration parameters to provide the Container Network Interface (CNI) plugin, specified as key-value pairs. + IgnoredUID - (Required) The user ID (UID) of the proxy container as defined by the user parameter in a container definition. This is used to ensure the proxy ignores its own traffic. If IgnoredGID is specified, this field can be empty. + IgnoredGID - (Required) The group ID (GID) of the proxy container as defined by the user parameter in a container definition. This is used to ensure the proxy ignores its own traffic. If IgnoredUID is specified, this field can be empty. + AppPorts - (Required) The list of ports that the application uses. Network traffic to these ports is forwarded to the ProxyIngressPort and ProxyEgressPort. + ProxyIngressPort - (Required) Specifies the port that incoming traffic to the AppPorts is directed to. + ProxyEgressPort - (Required) Specifies the port that outgoing traffic from the AppPorts is directed to. + EgressIgnoredPorts - (Required) The egress traffic going to the specified ports is ignored and not redirected to the ProxyEgressPort. It can be an empty list. + EgressIgnoredIPs - (Required) The egress traffic going to the specified IP addresses is ignored and not redirected to the ProxyEgressPort. It can be an empty list.	KeyValuePair[]

RepositoryCredentials

Name	Description	Value
credentialsParameter	The Amazon Resource Name (ARN) of the secret containing the private repository credentials. When you use the Amazon ECS API, CLI, or AWS SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the AWS Management Console, you must specify the full ARN of the secret.	string

ResourceRequirement

Name	Description	Value
type	The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator.	string
value	The value for the specified resource type. If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent reserves for the container. The number of GPUs that's reserved for all containers in a task can't exceed the number of available GPUs on the container instance that the task is launched on. If the InferenceAccelerator type is used, the value matches the deviceName for an InferenceAccelerator specified in a task definition.	string

Name	Description	Value
name	The name of the secret.	string
valueFrom	The secret to expose to the container. The supported values are either the full ARN of the ASMlong secret or the full ARN of the parameter in the SSM Parameter Store. For information about the require IAMlong permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide. If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.	string

SystemControl

Name	Description	Value
namespace	The namespaced kernel parameter to set a value for.	string

name	The type of the ulimit.	string
softLimit	The soft limit for the ulimit type.	int

Volume

Name	Description	Value
configuredAtLaunch	Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration. To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService, UpdateService, RunTask or StartTask APIs.	bool
dockerVolumeConfiguration	This parameter is specified when you use Docker volumes. Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead. Docker volumes aren't supported by tasks run on FARGATElong. The DockerVolumeConfiguration property specifies a Docker volume configuration and is used when you use Docker volumes. Docker volumes are only supported when you are using the EC2 launch type. Windows containers only support the use of the local driver. To use bind mounts, specify a host instead.	DockerVolumeConfiguration
efsVolumeConfiguration	This parameter is specified when you use an Amazon Elastic File System file system for task storage. This parameter is specified when you're using an Amazon Elastic File System file system for task storage. For more information, see Amazon EFS volumes in the Amazon Elastic Container Service Developer Guide.	EFSVolumeConfiguration
fSxWindowsFileServerVolumeConfiguration	This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage. This parameter is specified when you're using Amazon FSx for Windows File Server file system for task storage. For more information and the input format, see Amazon FSx for Windows File Server volumes in the Amazon Elastic Container Service Developer Guide.	FSxWindowsFileServerVolumeConfiguration
host	This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running. Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\, but not D:\my\path:C:\my\path or D:\:C:\my\path. The HostVolumeProperties property specifies details on a container instance bind mount host volume.	HostVolumeProperties
name	The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task. For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition. When a volume is using the efsVolumeConfiguration, the name is required.	string

VolumeFrom

Name	Description	Value
readOnly	If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.	bool

containerDefinitions	A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.	ContainerDefinition[]
cpu	The number of cpu units used by the task. If you use the EC2 launch type, this field is optional. Any value can be used. If you use the Fargate launch type, this field is required. You must use one of the following values. The value that you choose determines your range of valid values for the memory parameter. The CPU units cannot be less than 1 vCPU when you use Windows containers on Fargate. + 256 (.25 vCPU) - Available memory values: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) + 512 (.5 vCPU) - Available memory values: 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) + 1024 (1 vCPU) - Available memory values: 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) + 2048 (2 vCPU) - Available memory values: 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) + 4096 (4 vCPU) - Available memory values: 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) + 8192 (8 vCPU) - Available memory values: 16 GB and 60 GB in 4 GB increments This option requires Linux platform 1.4.0 or later. + 16384 (16vCPU) - Available memory values: 32GB and 120 GB in 8 GB increments This option requires Linux platform 1.4.0 or later.	string
ephemeralStorage	The ephemeral storage settings to use for tasks run with the task definition. The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on FARGATElong. For more information, see Using data volumes in tasks in the Amazon ECS Developer Guide;. For tasks using the Fargate launch type, the task requires the following platforms: + Linux platform version 1.4.0 or later. + Windows platform version 1.0.0 or later.	EphemeralStorage
executionRoleArn	The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make AWS API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide.	string
family	The name of a family that this task definition is registered to. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add. To use revision numbers when you update a task definition, specify this property. If you don't specify a value, CFNlong generates a new task definition each time that you update it.	string
inferenceAccelerators	The Elastic Inference accelerators to use for the containers in the task.	InferenceAccelerator[]
ipcMode	The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference. If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security. If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide. + For tasks that use the host IPC mode, IPC namespace related systemControls are not supported. + For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task. This parameter is not supported for Windows containers or tasks run on FARGATElong.	string
memory	The amount (in MiB) of memory used by the task. If your tasks runs on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified, the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition. If your tasks runs on FARGATElong, this field is required. You must use one of the following values. The value you choose determines your range of valid values for the cpu parameter. + 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU) + 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU) + 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU) + Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available cpu values: 2048 (2 vCPU) + Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available cpu values: 4096 (4 vCPU) + Between 16 GB and 60 GB in 4 GB increments - Available cpu values: 8192 (8 vCPU) This option requires Linux platform 1.4.0 or later. + Between 32GB and 120 GB in 8 GB increments - Available cpu values: 16384 (16 vCPU) This option requires Linux platform 1.4.0 or later.	string
networkMode	The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. If no network mode is specified, the default is bridge. For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode. With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings. When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user. If the network mode is awsvpc, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide. If the network mode is host, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used. For more information, see Network settings in the Docker run reference.	string
pidMode	The process namespace to use for the containers in the task. The valid values are host or task. On Fargate for Linux containers, the only valid value is task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task. If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same process namespace. If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference. If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security. This parameter is not supported for Windows containers. This parameter is only supported for tasks that are hosted on FARGATElong if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.	string
placementConstraints	An array of placement constraint objects to use for tasks. This parameter isn't supported for tasks run on FARGATElong.	TaskDefinitionPlacementConstraint[]
proxyConfiguration	The configuration details for the App Mesh proxy. Your Amazon ECS container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS optimized AMI version 20190301 or later, they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. The configuration details for the App Mesh proxy. For tasks that use the EC2 launch type, the container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS optimized AMI version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI	ProxyConfiguration
requiresCompatibilities	The task launch types the task definition was validated against. The valid values are EC2, FARGATE, and EXTERNAL. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.	string[]
runtimePlatform	The operating system that your tasks definitions run on. A platform family is specified only for tasks using the Fargate launch type. When you specify a task definition in a service, this value must match the runtimePlatform value of the service. Information about the platform for the Amazon ECS service or task. For more information about RuntimePlatform, see RuntimePlatform in the Amazon Elastic Container Service Developer Guide.	RuntimePlatform
tags	The metadata that you apply to the task definition to help you categorize and organize them. Each tag consists of a key and an optional value. You define both of them. The following basic restrictions apply to tags: + Maximum number of tags per resource - 50 + For each resource, each tag key must be unique, and each tag key can have only one value. + Maximum key length - 128 Unicode characters in UTF-8 + Maximum value length - 256 Unicode characters in UTF-8 + If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @. + Tag keys and values are case-sensitive. + Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for AWS use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.	TagAutoGenerated27[]
taskDefinitionArn	Property taskDefinitionArn	string
taskRoleArn	The short name or full Amazon Resource Name (ARN) of the IAMlong role that grants containers in the task permission to call AWS APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide. IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code to use the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide.	string
volumes	The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide. The host and sourcePath parameters aren't supported for tasks run on FARGATElong.	Volume[]

ContainerDefinition

Name	Description	Value
command	The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd. If there are multiple arguments, each argument is a separated string in the array.	string[]
cpu	The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value. You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024. Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units. On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version: + Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares. + Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2. On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0, which Windows interprets as 1% of one CPU.	int
credentialSpecs	A list of ARNs in SSM or Amazon S3 to a credential spec (CredSpec) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions. The maximum number of ARNs is 1. There are two formats for each ARN. + credentialspecdomainless:MyARN You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in . You provide the login credentials to the domain in the secret. Each task that runs on any container instance can join different domains. You can use this format without joining the container instance to a domain. + credentialspec:MyARN You use credentialspec:MyARN to provide a CredSpec for a single domain. You must join the container instance to the domain before you start any tasks that use this task definition. In both formats, replace MyARN with the ARN in SSM or Amazon S3. If you provide a credentialspecdomainless:MyARN, the credspec must provide a ARN in ASMlong for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.	string[]
dependsOn	The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed. For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. For tasks using the Fargate launch type, the task or service requires the following platforms: + Linux platform version 1.3.0 or later. + Windows platform version 1.0.0 or later. If the task definition is used in a blue/green deployment that uses AWS::CodeDeploy::DeploymentGroup BlueGreenDeploymentConfiguration, the dependsOn parameter is not supported. For more information see Issue #680 on the on the GitHub website.	ContainerDependency[]
disableNetworking	When this parameter is true, networking is off within the container. This parameter maps to NetworkDisabled in the Create a container section of the Docker Remote API. This parameter is not supported for Windows containers.	bool
dnsSearchDomains	A list of DNS search domains that are presented to the container. This parameter maps to DnsSearch in the Create a container section of the Docker Remote API and the --dns-search option to docker run. This parameter is not supported for Windows containers.	string[]
dnsServers	A list of DNS servers that are presented to the container. This parameter maps to Dns in the Create a container section of the Docker Remote API and the --dns option to docker run. This parameter is not supported for Windows containers.	string[]
dockerLabels	A key/value map of labels to add to the container. This parameter maps to Labels in the Create a container section of the Docker Remote API and the --label option to docker run. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'	any
dockerSecurityOptions	A list of strings to provide custom configuration for multiple security systems. For more information about valid values, see Docker Run Security Configuration. This field isn't valid for containers in tasks using the Fargate launch type. For Linux tasks on EC2, this parameter can be used to reference custom labels for SELinux and AppArmor multi-level security systems. For any tasks on EC2, this parameter can be used to reference a credential spec file that configures a container for Active Directory authentication. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers in the Amazon Elastic Container Service Developer Guide. This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API and the --security-opt option to docker run. The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide. For more information about valid values, see Docker Run Security Configuration. Valid values: 'no-new-privileges' | 'apparmor:PROFILE' | 'label:value' | 'credentialspec:CredentialSpecFilePath'	string[]
entryPoint	Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint, update your container agent or enter your commands and arguments as command array items instead. The entry point that's passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint.	string[]
environment	The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run. We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.	KeyValuePair[]
environmentFiles	A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run. You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored. For more information about the environment variable file syntax, see Declare default environment variables in file. If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.	EnvironmentFile[]
essential	If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential. All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.	bool
extraHosts	A list of hostnames and IP address mappings to append to the /etc/hosts file on the container. This parameter maps to ExtraHosts in the Create a container section of the Docker Remote API and the --add-host option to docker run. This parameter isn't supported for Windows containers or tasks that use the awsvpc network mode.	HostEntry[]
firelensConfiguration	The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide. The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom log routing in the Amazon Elastic Container Service Developer Guide.	FirelensConfiguration
healthCheck	The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run. The HealthCheck property specifies an object representing a container health check. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image (such as those specified in a parent image or from the image's Dockerfile). This configuration maps to the HEALTHCHECK parameter of docker run. The Amazon ECS container agent only monitors and reports on the health checks specified in the task definition. Amazon ECS does not monitor Docker health checks that are embedded in a container image and not specified in the container definition. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image. If a task is run manually, and not as part of a service, the task will continue its lifecycle regardless of its health status. For tasks that are part of a service, if the task reports as unhealthy then the task will be stopped and the service scheduler will replace it. The following are notes about container health check support: + Container health checks require version 1.17.0 or greater of the Amazon ECS container agent. For more information, see Updating the Amazon ECS Container Agent. + Container health checks are supported for Fargate tasks if you are using platform version 1.1.0 or greater. For more information, see Platform Versions. + Container health checks are not supported for tasks that are part of a service that is configured to use a Classic Load Balancer.	HealthCheck
hostname	The hostname to use for your container. This parameter maps to Hostname in the Create a container section of the Docker Remote API and the --hostname option to docker run. The hostname parameter is not supported if you're using the awsvpc network mode.	string
image	The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest. Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run. + When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks. + Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest. For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE. + Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo). + Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent). + Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu).	string
interactive	When this parameter is true, you can deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the Create a container section of the Docker Remote API and the --interactive option to docker run.	bool
links	The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run. This parameter is not supported for Windows containers. Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.	string[]
linuxParameters	Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities. This parameter is not supported for Windows containers. The Linux-specific options that are applied to the container, such as Linux KernelCapabilities.	LinuxParameters
logConfiguration	The log configuration specification for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However, the container may use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation. Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}' The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide. The LogConfiguration property specifies log configuration options to send to a custom log driver for the container.	LogConfiguration
memory	The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. If using the Fargate launch type, this parameter is optional. If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used. The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container, so you should not specify fewer than 6 MiB of memory for your containers. The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.	int
memoryReservation	The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run. If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used. For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed. The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers. The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.	int
mountPoints	The mount points for data volumes in your container. This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run. Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives.	MountPoint[]
name	The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run.	string
portMappings	The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic. For task definitions that use the awsvpc network mode, you should only specify the containerPort. The hostPort can be left blank or it must be the same value as the containerPort. Port mappings on Windows use the NetNAT gateway address rather than localhost. There is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself. This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to none, then you can't specify port mappings. If the network mode of a task definition is set to host, then host ports must either be undefined or they must match the container port in the port mapping. After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.	PortMapping[]
privileged	When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run. This parameter is not supported for Windows containers or tasks run on FARGATElong.	bool
pseudoTerminal	When this parameter is true, a TTY is allocated. This parameter maps to Tty in the Create a container section of the Docker Remote API and the --tty option to docker run.	bool
readonlyRootFilesystem	When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the Create a container section of the Docker Remote API and the --read-only option to docker run. This parameter is not supported for Windows containers.	bool
repositoryCredentials	The private repository authentication credentials to use. The repository credentials for private registry authentication.	RepositoryCredentials
resourceRequirements	The type and amount of a resource to assign to a container. The only supported resource is a GPU.	ResourceRequirement[]
secrets	The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.	Secret[]
startTimeout	Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE, SUCCESS, or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state. When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value. For tasks using the Fargate launch type, the task or service requires the following platforms: + Linux platform version 1.3.0 or later. + Windows platform version 1.0.0 or later. For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. The valid values are 2-120 seconds.	int
stopTimeout	Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own. For tasks using the Fargate launch type, the task or service requires the following platforms: + Linux platform version 1.3.0 or later. + Windows platform version 1.0.0 or later. The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used. For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. The valid values are 2-120 seconds.	int
systemControls	A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.	SystemControl[]
ulimits	A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}' This parameter is not supported for Windows containers.	Ulimit[]
user	The user to use inside the container. This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run. When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security. You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer. + user + user:group + uid + uid:gid + user:gid + uid:group This parameter is not supported for Windows containers.	string
volumesFrom	Data volumes to mount from another container. This parameter maps to VolumesFrom in the Create a container section of the Docker Remote API and the --volumes-from option to docker run.	VolumeFrom[]
workingDirectory	The working directory to run commands inside the container in. This parameter maps to WorkingDir in the Create a container section of the Docker Remote API and the --workdir option to docker run.	string

It validates that a dependent container is started before permitting other containers to start. + COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container. + SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container. + HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.	string

filesystemId	The Amazon EFS file system ID to use.	string
rootDirectory	The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter. If an EFS access point is specified in the authorizationConfig, the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.	string
transitEncryption	Determines whether to use encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be turned on if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide.	'DISABLED' 'ENABLED'
transitEncryptionPort	The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server.

Name	Description	Value
deviceName	The Elastic Inference accelerator device name. The deviceName must also be referenced in a container definition as a ResourceRequirement.	string
deviceType	The Elastic Inference accelerator type to use.	string

KernelCapabilities

Name	Description	Value
add	The Linux capabilities for the container that have been added to the default configuration provided by Docker. This parameter maps to CapAdd in the Create a container section of the Docker Remote API and the --cap-add option to docker run. Tasks launched on FARGATElong only support adding the SYS_PTRACE kernel capability. Valid values: 'ALL' \| 'AUDIT_CONTROL' \| 'AUDIT_WRITE' \| 'BLOCK_SUSPEND' \| 'CHOWN' \| 'DAC_OVERRIDE' \| 'DAC_READ_SEARCH' \| 'FOWNER' \| 'FSETID' \| 'IPC_LOCK' \| 'IPC_OWNER' \| 'KILL' \| 'LEASE' \| 'LINUX_IMMUTABLE' \| 'MAC_ADMIN' \| 'MAC_OVERRIDE' \| 'MKNOD' \| 'NET_ADMIN' \| 'NET_BIND_SERVICE' \| 'NET_BROADCAST' \| 'NET_RAW' \| 'SETFCAP' \| 'SETGID' \| 'SETPCAP' \| 'SETUID' \| 'SYS_ADMIN' \| 'SYS_BOOT' \| 'SYS_CHROOT' \| 'SYS_MODULE' \| 'SYS_NICE' \| 'SYS_PACCT' \| 'SYS_PTRACE' \| 'SYS_RAWIO' \| 'SYS_RESOURCE' \| 'SYS_TIME' \| 'SYS_TTY_CONFIG' \| 'SYSLOG' \| 'WAKE_ALARM'	string[]

For tasks that use the Fargate launch type, capabilities is supported for all platform versions but the add parameter is only supported if using platform version 1.4.0 or later. The Linux capabilities to add or remove from the default Docker configuration for a container defined in the task definition. For more information about the default capabilities and the non-default available capabilities, see Runtime privilege and Linux capabilities in the Docker run reference. For more detailed information about these Linux capabilities, see the capabilities(7) Linux manual page.	KernelCapabilities
devices	Any host devices to expose to the container. This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run. If you're using tasks that use the Fargate launch type, the devices parameter isn't supported.	Device[]
initProcessEnabled	Run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'	bool
maxSwap	The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value. If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used. If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.	int
sharedMemorySize	The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run. If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.	int
swappiness	This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100. If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run. If you're using tasks that use the Fargate launch type, the swappiness parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.	int

LogConfiguration

Name	Description	Value
logDriver	The log driver to use for the container. For tasks on FARGATElong, the supported log drivers are awslogs, splunk, and awsfirelens. For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries,syslog, splunk, and awsfirelens. For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide. For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide. If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.	string
options	The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'	any

MountPoint

Name	Description	Value
containerPath	The path on the container to mount the host volume at.	string
readOnly	If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.	bool
sourceVolume	The name of the volume to mount. Must be a volume name referenced in the name parameter of task definition volume.	string

PortMapping

Name	Description	Value
appProtocol	The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch. If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP. appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment. Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.	'grpc' 'http' 'http2'
containerPort	The port number on the container that's bound to the user-specified or automatically assigned host port. If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort. If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.	int
containerPortRange	The port number range on the container that's bound to the dynamically mapped host port range. The following rules apply when you specify a containerPortRange: + You must use either the bridge network mode or the awsvpc network mode. + This parameter is available for both the EC2 and FARGATElong launch types. + This parameter is available for both the Linux and Windows operating systems. + The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package + You can specify a maximum of 100 port ranges per container. + You do not specify a hostPortRange. The value of the hostPortRange is set as follows: + For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange. This is a static mapping strategy. + For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports. + The containerPortRange valid values are between 1 and 65535. + A port can only be included in one port mapping per container. + You cannot specify overlapping port ranges. + The first port in the range must be less than last port in the range. + Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide. You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.	string
hostPort	The port number on the container instance to reserve for your container. If you specify a containerPortRange, leave this field empty and the value of the hostPort is set as follows: + For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort. This is a static mapping strategy. + For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy. If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort. If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version. The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range. The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.	int
name	The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.	string
protocol	The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp. protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.	string

name	The type of the ulimit.	string
softLimit	The soft limit for the ulimit type.	int

Volume

Name	Description	Value
configuredAtLaunch	Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration. To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService, UpdateService, RunTask or StartTask APIs.	bool
dockerVolumeConfiguration	This parameter is specified when you use Docker volumes. Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead. Docker volumes aren't supported by tasks run on FARGATElong. The DockerVolumeConfiguration property specifies a Docker volume configuration and is used when you use Docker volumes. Docker volumes are only supported when you are using the EC2 launch type. Windows containers only support the use of the local driver. To use bind mounts, specify a host instead.	DockerVolumeConfiguration
efsVolumeConfiguration	This parameter is specified when you use an Amazon Elastic File System file system for task storage. This parameter is specified when you're using an Amazon Elastic File System file system for task storage. For more information, see Amazon EFS volumes in the Amazon Elastic Container Service Developer Guide.	EFSVolumeConfiguration
fSxWindowsFileServerVolumeConfiguration	This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage. This parameter is specified when you're using Amazon FSx for Windows File Server file system for task storage. For more information and the input format, see Amazon FSx for Windows File Server volumes in the Amazon Elastic Container Service Developer Guide.	FSxWindowsFileServerVolumeConfiguration
host	This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running. Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\, but not D:\my\path:C:\my\path or D:\:C:\my\path. The HostVolumeProperties property specifies details on a container instance bind mount host volume.	HostVolumeProperties
name	The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task. For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition. When a volume is using the efsVolumeConfiguration, the name is required.	string

VolumeFrom

Name	Description	Value
readOnly	If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.	bool
sourceContainer	The name of another container within the same task definition to mount volumes from.	string

For more information, see Using Amazon EFS access points in the Amazon Elastic Container Service Developer Guide.	'DISABLED' 'ENABLED'

AwsEcsTaskDefinitionProperties

Name	Description	Value
containerDefinitions	A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.	ContainerDefinition[]
cpu	The number of cpu units used by the task. If you use the EC2 launch type, this field is optional. Any value can be used. If you use the Fargate launch type, this field is required. You must use one of the following values. The value that you choose determines your range of valid values for the memory parameter. The CPU units cannot be less than 1 vCPU when you use Windows containers on Fargate. + 256 (.25 vCPU) - Available memory values: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) + 512 (.5 vCPU) - Available memory values: 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) + 1024 (1 vCPU) - Available memory values: 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) + 2048 (2 vCPU) - Available memory values: 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) + 4096 (4 vCPU) - Available memory values: 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) + 8192 (8 vCPU) - Available memory values: 16 GB and 60 GB in 4 GB increments This option requires Linux platform 1.4.0 or later. + 16384 (16vCPU) - Available memory values: 32GB and 120 GB in 8 GB increments This option requires Linux platform 1.4.0 or later.	string
ephemeralStorage	The ephemeral storage settings to use for tasks run with the task definition. The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on FARGATElong. For more information, see Using data volumes in tasks in the Amazon ECS Developer Guide;. For tasks using the Fargate launch type, the task requires the following platforms: + Linux platform version 1.4.0 or later. + Windows platform version 1.0.0 or later.	EphemeralStorage
executionRoleArn	The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make AWS API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide.	string
family	The name of a family that this task definition is registered to. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add. To use revision numbers when you update a task definition, specify this property. If you don't specify a value, CFNlong generates a new task definition each time that you update it.	string
inferenceAccelerators	The Elastic Inference accelerators to use for the containers in the task.	InferenceAccelerator[]
ipcMode	The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference. If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security. If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide. + For tasks that use the host IPC mode, IPC namespace related systemControls are not supported. + For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task. This parameter is not supported for Windows containers or tasks run on FARGATElong.	string
memory	The amount (in MiB) of memory used by the task. If your tasks runs on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified, the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition. If your tasks runs on FARGATElong, this field is required. You must use one of the following values. The value you choose determines your range of valid values for the cpu parameter. + 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU) + 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU) + 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU) + Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available cpu values: 2048 (2 vCPU) + Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available cpu values: 4096 (4 vCPU) + Between 16 GB and 60 GB in 4 GB increments - Available cpu values: 8192 (8 vCPU) This option requires Linux platform 1.4.0 or later. + Between 32GB and 120 GB in 8 GB increments - Available cpu values: 16384 (16 vCPU) This option requires Linux platform 1.4.0 or later.	string
networkMode	The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. If no network mode is specified, the default is bridge. For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode. With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings. When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user. If the network mode is awsvpc, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide. If the network mode is host, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used. For more information, see Network settings in the Docker run reference.	string
pidMode	The process namespace to use for the containers in the task. The valid values are host or task. On Fargate for Linux containers, the only valid value is task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task. If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same process namespace. If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference. If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security. This parameter is not supported for Windows containers. This parameter is only supported for tasks that are hosted on FARGATElong if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.	string
placementConstraints	An array of placement constraint objects to use for tasks. This parameter isn't supported for tasks run on FARGATElong.	TaskDefinitionPlacementConstraint[]
proxyConfiguration	The configuration details for the App Mesh proxy. Your Amazon ECS container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS optimized AMI version 20190301 or later, they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. The configuration details for the App Mesh proxy. For tasks that use the EC2 launch type, the container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS optimized AMI version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI	ProxyConfiguration
requiresCompatibilities	The task launch types the task definition was validated against. The valid values are EC2, FARGATE, and EXTERNAL. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.	string[]
runtimePlatform	The operating system that your tasks definitions run on. A platform family is specified only for tasks using the Fargate launch type. When you specify a task definition in a service, this value must match the runtimePlatform value of the service. Information about the platform for the Amazon ECS service or task. For more information about RuntimePlatform, see RuntimePlatform in the Amazon Elastic Container Service Developer Guide.	RuntimePlatform
tags	The metadata that you apply to the task definition to help you categorize and organize them. Each tag consists of a key and an optional value. You define both of them. The following basic restrictions apply to tags: + Maximum number of tags per resource - 50 + For each resource, each tag key must be unique, and each tag key can have only one value. + Maximum key length - 128 Unicode characters in UTF-8 + Maximum value length - 256 Unicode characters in UTF-8 + If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @. + Tag keys and values are case-sensitive. + Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for AWS use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.	TagAutoGenerated27[]
taskDefinitionArn	Property taskDefinitionArn	string
taskRoleArn	The short name or full Amazon Resource Name (ARN) of the IAMlong role that grants containers in the task permission to call AWS APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide. IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code to use the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide.	string
volumes	The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide. The host and sourcePath parameters aren't supported for tasks run on FARGATElong.	Volume[]

ContainerDefinition

Name	Description	Value
command	The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd. If there are multiple arguments, each argument is a separated string in the array.	string[]
cpu	The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value. You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024. Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units. On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version: + Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares. + Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2. On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0, which Windows interprets as 1% of one CPU.	int
credentialSpecs	A list of ARNs in SSM or Amazon S3 to a credential spec (CredSpec) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions. The maximum number of ARNs is 1. There are two formats for each ARN. + credentialspecdomainless:MyARN You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in . You provide the login credentials to the domain in the secret. Each task that runs on any container instance can join different domains. You can use this format without joining the container instance to a domain. + credentialspec:MyARN You use credentialspec:MyARN to provide a CredSpec for a single domain. You must join the container instance to the domain before you start any tasks that use this task definition. In both formats, replace MyARN with the ARN in SSM or Amazon S3. If you provide a credentialspecdomainless:MyARN, the credspec must provide a ARN in ASMlong for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.	string[]
dependsOn	The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed. For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. For tasks using the Fargate launch type, the task or service requires the following platforms: + Linux platform version 1.3.0 or later. + Windows platform version 1.0.0 or later. If the task definition is used in a blue/green deployment that uses AWS::CodeDeploy::DeploymentGroup BlueGreenDeploymentConfiguration, the dependsOn parameter is not supported. For more information see Issue #680 on the on the GitHub website.	ContainerDependency[]
disableNetworking	When this parameter is true, networking is off within the container. This parameter maps to NetworkDisabled in the Create a container section of the Docker Remote API. This parameter is not supported for Windows containers.	bool
dnsSearchDomains	A list of DNS search domains that are presented to the container. This parameter maps to DnsSearch in the Create a container section of the Docker Remote API and the --dns-search option to docker run. This parameter is not supported for Windows containers.	string[]
dnsServers	A list of DNS servers that are presented to the container. This parameter maps to Dns in the Create a container section of the Docker Remote API and the --dns option to docker run. This parameter is not supported for Windows containers.	string[]
dockerLabels	A key/value map of labels to add to the container. This parameter maps to Labels in the Create a container section of the Docker Remote API and the --label option to docker run. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'	any
dockerSecurityOptions	A list of strings to provide custom configuration for multiple security systems. For more information about valid values, see Docker Run Security Configuration. This field isn't valid for containers in tasks using the Fargate launch type. For Linux tasks on EC2, this parameter can be used to reference custom labels for SELinux and AppArmor multi-level security systems. For any tasks on EC2, this parameter can be used to reference a credential spec file that configures a container for Active Directory authentication. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers in the Amazon Elastic Container Service Developer Guide. This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API and the --security-opt option to docker run. The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide. For more information about valid values, see Docker Run Security Configuration. Valid values: 'no-new-privileges' | 'apparmor:PROFILE' | 'label:value' | 'credentialspec:CredentialSpecFilePath'	string[]
entryPoint	Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint, update your container agent or enter your commands and arguments as command array items instead. The entry point that's passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint.	string[]
environment	The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run. We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.	KeyValuePair[]
environmentFiles	A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run. You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored. For more information about the environment variable file syntax, see Declare default environment variables in file. If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.	EnvironmentFile[]
essential	If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential. All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.	bool
extraHosts	A list of hostnames and IP address mappings to append to the /etc/hosts file on the container. This parameter maps to ExtraHosts in the Create a container section of the Docker Remote API and the --add-host option to docker run. This parameter isn't supported for Windows containers or tasks that use the awsvpc network mode.	HostEntry[]
firelensConfiguration	The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide. The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom log routing in the Amazon Elastic Container Service Developer Guide.	FirelensConfiguration
healthCheck	The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run. The HealthCheck property specifies an object representing a container health check. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image (such as those specified in a parent image or from the image's Dockerfile). This configuration maps to the HEALTHCHECK parameter of docker run. The Amazon ECS container agent only monitors and reports on the health checks specified in the task definition. Amazon ECS does not monitor Docker health checks that are embedded in a container image and not specified in the container definition. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image. If a task is run manually, and not as part of a service, the task will continue its lifecycle regardless of its health status. For tasks that are part of a service, if the task reports as unhealthy then the task will be stopped and the service scheduler will replace it. The following are notes about container health check support: + Container health checks require version 1.17.0 or greater of the Amazon ECS container agent. For more information, see Updating the Amazon ECS Container Agent. + Container health checks are supported for Fargate tasks if you are using platform version 1.1.0 or greater. For more information, see Platform Versions. + Container health checks are not supported for tasks that are part of a service that is configured to use a Classic Load Balancer.	HealthCheck
hostname	The hostname to use for your container. This parameter maps to Hostname in the Create a container section of the Docker Remote API and the --hostname option to docker run. The hostname parameter is not supported if you're using the awsvpc network mode.	string
image	The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest. Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run. + When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks. + Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest. For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE. + Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo). + Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent). + Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu).	string
interactive	When this parameter is true, you can deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the Create a container section of the Docker Remote API and the --interactive option to docker run.	bool
links	The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run. This parameter is not supported for Windows containers. Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.	string[]
linuxParameters	Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities. This parameter is not supported for Windows containers. The Linux-specific options that are applied to the container, such as Linux KernelCapabilities.	LinuxParameters
logConfiguration	The log configuration specification for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However, the container may use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation. Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}' The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide. The LogConfiguration property specifies log configuration options to send to a custom log driver for the container.	LogConfiguration
memory	The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. If using the Fargate launch type, this parameter is optional. If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used. The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container, so you should not specify fewer than 6 MiB of memory for your containers. The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.	int
memoryReservation	The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run. If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used. For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed. The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers. The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.	int
mountPoints	The mount points for data volumes in your container. This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run. Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives.	MountPoint[]
name	The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run.	string
portMappings	The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic. For task definitions that use the awsvpc network mode, you should only specify the containerPort. The hostPort can be left blank or it must be the same value as the containerPort. Port mappings on Windows use the NetNAT gateway address rather than localhost. There is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself. This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to none, then you can't specify port mappings. If the network mode of a task definition is set to host, then host ports must either be undefined or they must match the container port in the port mapping. After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.	PortMapping[]
privileged	When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run. This parameter is not supported for Windows containers or tasks run on FARGATElong.	bool
pseudoTerminal	When this parameter is true, a TTY is allocated. This parameter maps to Tty in the Create a container section of the Docker Remote API and the --tty option to docker run.	bool
readonlyRootFilesystem	When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the Create a container section of the Docker Remote API and the --read-only option to docker run. This parameter is not supported for Windows containers.	bool
repositoryCredentials	The private repository authentication credentials to use. The repository credentials for private registry authentication.	RepositoryCredentials
resourceRequirements	The type and amount of a resource to assign to a container. The only supported resource is a GPU.	ResourceRequirement[]
secrets	The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.	Secret[]
startTimeout	Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE, SUCCESS, or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state. When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value. For tasks using the Fargate launch type, the task or service requires the following platforms: + Linux platform version 1.3.0 or later. + Windows platform version 1.0.0 or later. For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. The valid values are 2-120 seconds.	int
stopTimeout	Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own. For tasks using the Fargate launch type, the task or service requires the following platforms: + Linux platform version 1.3.0 or later. + Windows platform version 1.0.0 or later. The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used. For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. The valid values are 2-120 seconds.	int
systemControls	A list of namespaced kernel parameters to set in the container.

ulimits	A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}' This parameter is not supported for Windows containers.	Ulimit[]
user	The user to use inside the container. This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run. When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security. You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer. + user + user:group + uid + uid:gid + user:gid + uid:group This parameter is not supported for Windows containers.	string
volumesFrom	Data volumes to mount from another container. This parameter maps to VolumesFrom in the Create a container section of the Docker Remote API and the --volumes-from option to docker run.	VolumeFrom[]

The Linux capabilities to add or remove from the default Docker configuration for a container defined in the task definition. For more information about the default capabilities and the non-default available capabilities, see Runtime privilege and Linux capabilities in the Docker run reference. For more detailed information about these Linux capabilities, see the capabilities(7) Linux manual page.	KernelCapabilities
devices	Any host devices to expose to the container. This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run. If you're using tasks that use the Fargate launch type, the devices parameter isn't supported.	Device[]
initProcessEnabled	Run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'	bool
maxSwap	The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value. If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used. If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.	int
sharedMemorySize	The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run. If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.	int
swappiness	This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100. If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run. If you're using tasks that use the Fargate launch type, the swappiness parameter isn't supported. If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.	int

PortMapping

Name	Description	Value
appProtocol	The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch. If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP. appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment. Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.	'grpc' 'http' 'http2'
containerPort	The port number on the container that's bound to the user-specified or automatically assigned host port. If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort. If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.	int
containerPortRange	The port number range on the container that's bound to the dynamically mapped host port range. The following rules apply when you specify a containerPortRange: + You must use either the bridge network mode or the awsvpc network mode. + This parameter is available for both the EC2 and FARGATElong launch types. + This parameter is available for both the Linux and Windows operating systems. + The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package + You can specify a maximum of 100 port ranges per container. + You do not specify a hostPortRange. The value of the hostPortRange is set as follows: + For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange. This is a static mapping strategy. + For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports. + The containerPortRange valid values are between 1 and 65535. + A port can only be included in one port mapping per container. + You cannot specify overlapping port ranges. + The first port in the range must be less than last port in the range. + Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide. You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.	string
hostPort	The port number on the container instance to reserve for your container. If you specify a containerPortRange, leave this field empty and the value of the hostPort is set as follows: + For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort. This is a static mapping strategy. + For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy. If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort. If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version. The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range. The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.	int
name	The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.	string
protocol	The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp. protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.	string

TagAutoGenerated27

Name	Description	Value
key	One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.	string
value	The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).	string

TaskDefinitionPlacementConstraint

Name	Description	Value
expression	A cluster query language expression to apply to the constraint. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide.	string
type	The type of constraint. The MemberOf constraint restricts selection to be from a group of valid candidates.	string

Tmpfs

Name	Description	Value
containerPath	The absolute file path where the tmpfs volume is to be mounted.	string
mountOptions	The list of tmpfs volume mount options.	string[]
size	The maximum size (in MiB) of the tmpfs volume.	int

TrackedResourceTags

Name	Description	Value

Ulimit

Name	Description	Value
hardLimit	The hard limit for the ulimit type.	int
name	The type of the ulimit.	string
softLimit	The soft limit for the ulimit type.	int

Volume

Name	Description	Value
configuredAtLaunch	Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration. To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService, UpdateService, RunTask or StartTask APIs.	bool
dockerVolumeConfiguration	This parameter is specified when you use Docker volumes. Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead. Docker volumes aren't supported by tasks run on FARGATElong. The DockerVolumeConfiguration property specifies a Docker volume configuration and is used when you use Docker volumes. Docker volumes are only supported when you are using the EC2 launch type. Windows containers only support the use of the local driver. To use bind mounts, specify a host instead.	DockerVolumeConfiguration
efsVolumeConfiguration	This parameter is specified when you use an Amazon Elastic File System file system for task storage. This parameter is specified when you're using an Amazon Elastic File System file system for task storage. For more information, see Amazon EFS volumes in the Amazon Elastic Container Service Developer Guide.	EFSVolumeConfiguration
fSxWindowsFileServerVolumeConfiguration	This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage. This parameter is specified when you're using Amazon FSx for Windows File Server file system for task storage. For more information and the input format, see Amazon FSx for Windows File Server volumes in the Amazon Elastic Container Service Developer Guide.	FSxWindowsFileServerVolumeConfiguration
host	This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running. Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\, but not D:\my\path:C:\my\path or D:\:C:\my\path. The HostVolumeProperties property specifies details on a container instance bind mount host volume.	HostVolumeProperties
name	The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task. For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition. When a volume is using the efsVolumeConfiguration, the name is required.	string

VolumeFrom

Name	Description	Value
readOnly	If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.	bool
sourceContainer	The name of another container within the same task definition to mount volumes from.	string
