ManagedClusterAgentPoolProfileProperties interface

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

AKS will associate the specified agent pool with the Capacity Reservation Group.

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.

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

If orchestratorVersion is a fully specified version <major.minor.patch>, this field will be exactly equal to it. If orchestratorVersion is <major.minor>, this field will contain the full <major.minor.patch> version being used. NOTE: This property will not be serialized. It can only be populated by the server.

Whether to enable auto-scaler

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

See Add a FIPS-enabled node pool for more details.

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.

Whether to enable UltraSSD

GPUInstanceProfile to be used to specify GPU MIG instance profile for supported GPU VM SKU.

This is of the form: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/hostGroups/{hostGroupName}. For more information see Azure dedicated hosts.

The Kubelet configuration on the agent pool nodes.

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

The OS configuration of Linux agent nodes.

The maximum number of nodes for auto-scaling

The maximum number of pods that can run on a node.

The minimum number of nodes for auto-scaling

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

Network-related settings of an agent pool.

The version of node image NOTE: This property will not be serialized. It can only be populated by the server.

The node labels to be persisted across all nodes in agent pool.

This is of the form: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/publicIPPrefixes/{publicIPPrefixName}

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

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.

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.

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.

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.

The operating system type. The default is Linux.

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}

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

The current deployment or provisioning state. NOTE: This property will not be serialized. It can only be populated by the server.

The ID for Proximity Placement Group.

This also effects the cluster autoscaler behavior. If not specified, it defaults to Delete.

This cannot be specified unless the scaleSetPriority is 'Spot'. If not specified, the default is 'Delete'.

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

The security settings of an agent pool.

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

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

The type of Agent Pool.

Settings for upgrading the agentpool

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

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}

The Windows agent pool's specific profile.

Determines the type of workload a node can run.
