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

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

KubeletConfig

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

KubeletDiskType

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

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

AgentPoolMode

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.networkProfile

AgentPoolNetworkProfile

Network-related settings of an agent pool.
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

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

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

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

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

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

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}
