Learn to manage a workload profiles environment using the Azure CLI.

Create a container app in a profile

By default, your Container Apps environment is created with a managed VNet that is automatically generated for you. Generated VNets are inaccessible to you as they're created in Microsoft's tenant.

Alternatively, you can create an environment with a custom VNet if you need any of the following features:

User defined routes
Integration with Application Gateway
Network Security Groups
Communicating with resources behind private endpoints in your virtual network

When you create an environment with a custom VNet, you have full control over the VNet configuration. This amount of control gives you the option to implement the following features:

User defined routes
Integration with Application Gateway
Network Security Groups
Communicating with resources behind private endpoints in your virtual network

Use the following commands to create a workload profiles environment.

Create a VNet.

az network vnet create \
  --address-prefixes 13.0.0.0/23 \
  --resource-group "<RESOURCE_GROUP>" \
  --location "<LOCATION>" \
  --name "<VNET_NAME>"

Create a subnet delegated to Microsoft.App/environments.

az network vnet subnet create \
  --address-prefixes 13.0.0.0/23 \
  --delegations Microsoft.App/environments \
  --name "<SUBNET_NAME>" \
  --resource-group "<RESOURCE_GROUP>" \
  --vnet-name "<VNET_NAME>" \
  --query "id"

Copy the ID value and paste into the next command.

The Microsoft.App/environments delegation is required to give the Container Apps runtime the required control over your VNet to run workload profiles in the Container Apps environment.

You can specify as small as a /27 CIDR (32 IPs-8 reserved) for the subnet. If you're going to specify a /27 CIDR, consider the following items:

There are 11 IP addresses reserved for Container Apps infrastructure. Therefore, a /27 CIDR has a maximum of 21 available IP addresses.

IP addresses are allocated differently between Consumption only and Dedicated plans:

Consumption only	Dedicated
Every replica requires one IP. Users can't have apps with more than 21 replicas across all apps. Zero downtime deployment requires double the IPs since the old revision is running until the new revision is successfully deployed.	Every instance (VM node) requires a single IP. You can have up to 21 instances across all workload profiles, and hundreds or more replicas running on these workload profiles.

Create workload profiles environment

Note

You can configure whether your container app allows public ingress or only ingress from within your VNet at the environment level. In order to restrict ingress to just your VNet, set the --internal-only flag.

External environment
Internal environment

az containerapp env create \
  --enable-workload-profiles \
  --resource-group "<RESOURCE_GROUP>" \
  --name "<NAME>" \
  --location "<LOCATION>"

az containerapp env create \
  --enable-workload-profiles \
  --resource-group "<RESOURCE_GROUP>" \
  --name "<NAME>" \
  --location "<LOCATION>" \
  --infrastructure-subnet-resource-id "<SUBNET_ID>" \
  --internal-only true

az containerapp env create \
  --enable-workload-profiles \
  --resource-group "<RESOURCE_GROUP>" \
  --name "<NAME>" \
  --location "<LOCATION>"

This command can take up to 10 minutes to complete.

Check the status of your environment. The following command reports if the environment is created successfully.
```
az containerapp env show \
  --name "<ENVIRONMENT_NAME>" \
  --resource-group "<RESOURCE_GROUP>"
```
The provisioningState needs to report Succeeded before moving on to the next command.

Create a new container app.

External environment
Internal environment

az containerapp create \
  --resource-group "<RESOURCE_GROUP>" \
  --name "<CONTAINER_APP_NAME>" \
  --target-port 80 \
  --ingress external \
  --image mcr.microsoft.com/k8se/quickstart:latest \
  --environment "<ENVIRONMENT_NAME>" \
  --workload-profile-name "Consumption"

az containerapp create \
  --resource-group "<RESOURCE_GROUP>" \
  --name "<CONTAINER_APP_NAME>" \
  --target-port 80 \
  --ingress internal \
  --image mcr.microsoft.com/k8se/quickstart:latest \
  --environment "<ENVIRONMENT_NAME>" \
  --workload-profile-name "Consumption"

This command deploys the application to the built-in Consumption workload profile. If you want to create an app in a Dedicated profile, you first need to add the profile to the environment.

This command creates the new application in the environment using a specific workload profile.

Add profiles

Add a new workload profile to an existing environment.

az containerapp env workload-profile add \
  --resource-group <RESOURCE_GROUP> \
  --name <ENVIRONMENT_NAME> \
  --workload-profile-type <WORKLOAD_PROFILE_TYPE> \
  --workload-profile-name <WORKLOAD_PROFILE_NAME> \
  --min-nodes <MIN_NODES> \
  --max-nodes <MAX_NODES>

The value you select for the <WORKLOAD_PROFILE_NAME> placeholder is the workload profile friendly name.

Using friendly names allow you to add multiple profiles of the same type to an environment. The friendly name is what you use as you deploy and maintain a container app in a workload profile.

Edit profiles

You can modify the minimum and maximum number of nodes used by a workload profile via the update command.

az containerapp env workload-profile update \
  --resource-group <RESOURCE_GROUP> \
  --name <ENV_NAME> \
  --workload-profile-type <WORKLOAD_PROFILE_TYPE> \
  --workload-profile-name <WORKLOAD_PROFILE_NAME> \
  --min-nodes <MIN_NODES> \
  --max-nodes <MAX_NODES>

Delete a profile

Use the following command to delete a workload profile.

az containerapp env workload-profile delete \
  --resource-group "<RESOURCE_GROUP>" \
  --name <ENVIRONMENT_NAME> \
  --workload-profile-name <WORKLOAD_PROFILE_NAME>

Note

The Consumption workload profile can’t be deleted.

Inspect profiles

The following commands allow you to list available profiles in your region and ones used in a specific environment.

List available workload profiles

Use the list-supported command to list the supported workload profiles for your region.

The following Azure CLI command displays the results in a table.

az containerapp env workload-profile list-supported \
  --location <LOCATION>  \
  --query "[].{Name: name, Cores: properties.cores, MemoryGiB: properties.memoryGiB, Category: properties.category}" \
  -o table

The response resembles a table similar to the below example:

Name         Cores    MemoryGiB    Category
-----------  -------  -----------  ---------------
D4           4        16           GeneralPurpose
D8           8        32           GeneralPurpose
D16          16       64           GeneralPurpose
E4           4        32           MemoryOptimized
E8           8        64           MemoryOptimized
E16          16       128          MemoryOptimized
E32          32       256          MemoryOptimized
Consumption  4        8            Consumption

Select a workload profile and use the Name field when you run az containerapp env workload-profile set for the --workload-profile-type option.

Show a workload profile

Display details about a workload profile.

az containerapp env workload-profile show \
  --resource-group <RESOURCE_GROUP> \
  --name <ENVIRONMENT_NAME> \
  --workload-profile-name <WORKLOAD_PROFILE_NAME>
