Microsoft has simply introduced the supply of Azure Linux 3.0 for Azure Kubernetes Service (AKS), which is now to be had as a preview on AKS model 1.31. Azure Linux 3.0 used to be made usually to be had a couple of months in the past on GitHub; you’ll see the complete free up notes right here.

Azure Linux 3.0 comes 3 years after Azure Linux 2.0 (referred to as Mariner) and contains a number of upgrades to primary parts. For instance, the Linux Kernel has jumped from model 5.15 to six.6, Containerd has jumped from 1.6.26 to at least one.7.13 (2.0 can be to be had when in a position), SystemD has been upgraded from model 250 to 255, and OpenSSL has long past from model 1.1.1k to a few.3.0.

If you wish to have to make use of the Azure Linux 3.0 preview in AKS 1.31, you want to sign in the characteristic flag to your Azure subscription; you’ll do this with the next command:

• az characteristic sign in --namespace Microsoft.ContainerService --name AzureLinuxV3Preview

You can then test the registration standing with the next command. It will take a couple of mins for the standing to turn as Registered:

• az characteristic display --namespace Microsoft.ContainerService --name AzureLinuxV3Preview

When you create new clusters or node swimming pools with the ‘–os-sku=AzureLinux’ possibility, it’s going to default to the usage of the brand new Azure Linux 3.0. Microsoft says you’ll deploy clusters or node swimming pools the usage of a lot of strategies, together with:

• CLI
• PowerShell
• Terraform
• ARM

Microsoft stated there are 3 issues that folks want to remember about this preview:

• Please be aware that Azure Linux 3.0 Preview is best supported on AKS model 1.31, and therefore now not supported on AKS variations 1.30 and underneath. If you sign in the Azure Linux 3.0 preview characteristic flag on AKS variations 1.30 and underneath new AKS clusters and node swimming pools will default to the usage of Azure Linux 2.0.
• Further, all through preview present clusters or node swimming pools operating Azure Linux 2.0 can’t be upgraded to a few.0. New node swimming pools or clusters want to be created for Azure Linux 3.0 Preview.
• Finally, Azure Linux 3.0 toughen is in preview as a part of the v20241025 free up. Visit the AKS Release Tracker for the most recent on which areas are in this free up.

Going ahead, Microsoft says it’s going to incorporate comments from the preview duration to arrange the overall availability of Azure Linux 3.0 on AKS model 1.32.
