What is Azure Hybrid Benefit for Azure Kubernetes Service?

Azure Hybrid Benefit is a program that enables you to significantly reduce the costs of running workloads in the cloud. With Azure Hybrid Benefit for Azure Kubernetes Service (AKS), you can maximize the value of your on-premises licenses and modernize your applications at no extra cost. Azure Hybrid Benefit enables you to use your on-premises licenses that also have either active Software Assurance (SA) or a qualifying subscription to get Windows virtual machines (VMs) on Azure at a reduced cost.

Enable Azure Hybrid Benefit for Azure Kubernetes Service

Azure Hybrid Benefit for Azure Kubernetes Service can be enabled at cluster creation or on an existing AKS cluster. You can enable and disable Azure Hybrid Benefit using either the Azure CLI or Azure PowerShell. In the following examples, be sure to replace the variable definitions with values matching your own cluster.

Use Azure CLI to manage Azure Hybrid Benefit for AKS

To create a new AKS cluster with Azure Hybrid Benefit enabled:

PASSWORD='tempPassword1234$'
RG_NAME='myResourceGroup'
CLUSTER='myAKSCluster'

az aks create --resource-group $RG_NAME --name $CLUSTER --load-balancer-sku Standard --network-plugin azure --windows-admin-username azure --windows-admin-password $PASSWORD --enable-ahub

To enable Azure Hybrid Benefit on an existing AKS cluster:

RG_NAME='myResourceGroup'
CLUSTER='myAKSCluster'

az aks update --resouce-group $RG_NAME --name $CLUSTER--enable-ahub

To disable Azure Hybrid Benefit for an AKS cluster:

RG_NAME='myResourceGroup'
CLUSTER='myAKSCluster'

az aks update --resource-group $RG_NAME --name $CLUSTER --disable-ahub

Use Azure PowerShell to manage Azure Hybrid Benefit for AKS

To create a new AKS cluster with Azure Hybrid Benefit enabled:

$password= ConvertTo-SecureString -AsPlainText "Password!!123" -Force
$rg_name = "myResourceGroup"
$cluster = "myAKSCluster"

New-AzAksCluster -ResourceGroupName $rg_name -Name $cluster -WindowsProfileAdminUserName azureuser -WindowsProfileAdminUserPassword $cred -NetworkPlugin azure -NodeVmSetType VirtualMachineScaleSets --EnableAHUB

To enable Azure Hybrid Benefit on an existing AKS cluster:

$rg_name = "myResourceGroup"
$cluster = "myAKSCluster"

Get-AzAksCluster -ResourceGroupName $rg_name -Name $cluster | Set-AzAksCluster -EnableAHUB
