Request Body

Name Type Description
properties.availabilityZones
  • string[]

The list of Availability zones to use for nodes. This can only be specified if the AgentPoolType property is 'VirtualMachineScaleSets'.
properties.count
  • integer

Number of agents (VMs) to host docker containers. Allowed values must be in the range of 0 to 1000 (inclusive) for user pools and in the range of 1 to 1000 (inclusive) for system pools. The default value is 1.
properties.creationData

CreationData to be used to specify the source Snapshot ID if the node pool will be created/upgraded using a snapshot.
properties.enableAutoScaling
  • boolean

Whether to enable auto-scaler
properties.enableEncryptionAtHost
  • boolean

Whether to enable host based OS and data drive encryption.
This is only supported on certain VM sizes and in certain Azure regions. For more information, see: https://docs.microsoft.com/azure/aks/enable-host-encryption
properties.enableFIPS
  • boolean

Whether to use a FIPS-enabled OS.
See Add a FIPS-enabled node pool for more details.
properties.enableNodePublicIP
  • boolean

Whether each node is allocated its own public IP.
Some scenarios may require nodes in a node pool to receive their own dedicated public IP addresses. A common scenario is for gaming workloads, where a console needs to make a direct connection to a cloud virtual machine to minimize hops. For more information see assigning a public IP per node. The default is false.
properties.enableUltraSSD
  • boolean

Whether to enable UltraSSD
properties.gpuInstanceProfile

GPUInstanceProfile to be used to specify GPU MIG instance profile for supported GPU VM SKU.
properties.hostGroupID
  • string

The fully qualified resource ID of the Dedicated Host Group to provision virtual machines from, used only in creation scenario and not allowed to changed once set.
This is of the form: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/hostGroups/{hostGroupName}. For more information see Azure dedicated hosts.
properties.kubeletConfig

Kubelet configurations of agent nodes.
The Kubelet configuration on the agent pool nodes.
properties.kubeletDiskType

Determines the placement of emptyDir volumes, container runtime data root, and Kubelet ephemeral storage.
properties.linuxOSConfig

OS configurations of Linux agent nodes.
The OS configuration of Linux agent nodes.
properties.maxCount
  • integer

The maximum number of nodes for auto-scaling
properties.maxPods
  • integer

The maximum number of pods that can run on a node.
properties.minCount
  • integer

The minimum number of nodes for auto-scaling
properties.mode

The mode of an agent pool.
A cluster must have at least one 'System' Agent Pool at all times. For additional information on agent pool restrictions and best practices, see: https://docs.microsoft.com/azure/aks/use-system-pools
properties.nodeLabels
  • object

The node labels to be persisted across all nodes in agent pool.
properties.nodePublicIPPrefixID
  • string

The public IP prefix ID which VM nodes should use IPs from.
This is of the form: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/publicIPPrefixes/{publicIPPrefixName}
properties.nodeTaints
  • string[]

The taints added to new nodes during node pool create and scale. For example, key=value:NoSchedule.
properties.orchestratorVersion
  • string

The version of Kubernetes specified by the user.
Both patch version <major.minor.patch> (e.g. 1.20.13) and <major.minor> (e.g. 1.20) are supported. When <major.minor> is specified, the latest supported GA patch version is chosen automatically. Updating the cluster with the same <major.minor> once it has been created (e.g. 1.14.x -> 1.14) will not trigger an upgrade, even if a newer patch version is available. As a best practice, you should upgrade all node pools in an AKS cluster to the same Kubernetes version. The node pool version must have the same major version as the control plane. The node pool minor version must be within two minor versions of the control plane version. The node pool version cannot be greater than the control plane version. For more information see upgrading a node pool.
properties.osDiskSizeGB
  • integer

OS Disk Size in GB to be used to specify the disk size for every machine in the master/agent pool. If you specify 0, it will apply the default osDisk size according to the vmSize specified.
properties.osDiskType

The OS disk type to be used for machines in the agent pool.
The default is 'Ephemeral' if the VM supports it and has a cache disk larger than the requested OSDiskSizeGB. Otherwise, defaults to 'Managed'. May not be changed after creation. For more information see Ephemeral OS.
properties.osSKU

Specifies the OS SKU used by the agent pool. The default is Ubuntu if OSType is Linux. The default is Windows2019 when Kubernetes <= 1.24 or Windows2022 when Kubernetes >= 1.25 if OSType is Windows.
properties.osType

The operating system type. The default is Linux.
properties.podSubnetID
  • string

The ID of the subnet which pods will join when launched.
If omitted, pod IPs are statically assigned on the node subnet (see vnetSubnetID for more details). This is of the form: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/virtualNetworks/{virtualNetworkName}/subnets/{subnetName}
properties.powerState

Whether the Agent Pool is running or stopped.
When an Agent Pool is first created it is initially Running. The Agent Pool can be stopped by setting this field to Stopped. A stopped Agent Pool stops all of its VMs and does not accrue billing charges. An Agent Pool can only be stopped if it is Running and provisioning state is Succeeded
properties.proximityPlacementGroupID
  • string

The ID for Proximity Placement Group.
properties.scaleDownMode

The scale down mode to use when scaling the Agent Pool.
This also effects the cluster autoscaler behavior. If not specified, it defaults to Delete.
properties.scaleSetEvictionPolicy

The Virtual Machine Scale Set eviction policy to use.
This cannot be specified unless the scaleSetPriority is 'Spot'. If not specified, the default is 'Delete'.
properties.scaleSetPriority

The Virtual Machine Scale Set priority. If not specified, the default is 'Regular'.
properties.spotMaxPrice
  • number

The max price (in US Dollars) you are willing to pay for spot instances. Possible values are any decimal value greater than zero or -1 which indicates default price to be up-to on-demand.
Possible values are any decimal value greater than zero or -1 which indicates the willingness to pay any on-demand price. For more details on spot pricing, see spot VMs pricing
properties.tags
  • object

The tags to be persisted on the agent pool virtual machine scale set.
properties.type

The type of Agent Pool.
properties.upgradeSettings

Settings for upgrading the agentpool
properties.vmSize
  • string

The size of the agent pool VMs.
VM size availability varies by region. If a node contains insufficient compute resources (memory, cpu, etc) pods might fail to run correctly. For more details on restricted VM sizes, see: https://docs.microsoft.com/azure/aks/quotas-skus-regions
properties.vnetSubnetID
  • string

The ID of the subnet which agent pool nodes and optionally pods will join on startup.
If this is not specified, a VNET and subnet will be generated and used. If no podSubnetID is specified, this applies to nodes and pods, otherwise it applies to just nodes. This is of the form: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/virtualNetworks/{virtualNetworkName}/subnets/{subnetName}
properties.workloadRuntime

Determines the type of workload a node can run.

Updating the cluster with the same <major.minor> once it has been created (e.g. 1.14.x -> 1.14) will not trigger an upgrade, even if a newer patch version is available. As a best practice, you should upgrade all node pools in an AKS cluster to the same Kubernetes version. The node pool version must have the same major version as the control plane.
