Quickstart: Enable Azure Linux 3.0 for Azure Kubernetes Service (AKS) clusters and node pools

Starting with AKS version 1.32, Azure Linux 3.0 is the default Azure Linux node OS for AKS clusters and node pools.

Limitations

• Azure Linux 3.0 is not supported on Kubernetes version 1.30 and below. Azure Linux 3.0 Preview is supported on Kubernetes version 1.31.
• Use the az-aks-get-versions command to accurately capture if Kubernetes version 1.32 is available in your region.

Create new Azure Linux 3.0 clusters and node pools

Any new AKS clusters or node pools created using the --os-sku=AzureLinux flag and that run AKS version 1.32 default to Azure Linux 3.0. You can deploy clusters or node pools using the method of your choice to use Azure Linux 3.0 as the node OS:

• Quickstart with CLI
• Quickstart with PowerShell
• Quickstart with Terraform
• Quickstart with Azure Resource Manager (ARM)

Upgrade existing Azure Linux 2.0 clusters and node pools to Azure Linux 3.0

To upgrade existing Azure Linux 2.0 clusters and node pools to Azure Linux 3.0, you can upgrade them to AKS version 1.32. For more information about AKS cluster upgrades, see Upgrade an AKS cluster.
