AKS - Release 2022-11-06

Published by CocoWang-wql almost 2 years ago

Release 2022-11-06

Monitor the release status by regions at AKS-Release-Tracker.

Announcements

  • AKS is retiring v1.22.x on December 4th 2022. Please upgrade your clusters to v1.23 and above.
  • On December 4th 2022, AKS is updating all patch's on supported Kubernetes versions. This means that the oldest patch version on a supported minor version will be deprecated. Read more about AKS versioning and our policy here.
  • Some AKS labels are being deprecated with the Kubernetes 1.26 release. Update your AKS labels to the recommended substitutions. See more information on label deprecations and how to update your labels in the Use labels in an AKS cluster documentation.
  • AKS begins pod security policy deprecation on 2022-11-01 API. The pod security policy will be removed completely on 2023-06-01 API with AKS 1.25 version or higher. You can migrate pod security policy to pod security admission controller before the deprecation deadline.
  • Azure NAT gateways do not support IPv6 and therefore cannot be used with dual-stack clusters as the cluster would not have a valid IPv6 outbound connection.
  • AKS clusters with Calico enabled should not upgrade to Kubernetes v1.25 preview.

AKS - Release 2022-10-30

Release 2022-10-30

Monitor the release status by regions at AKS-Release-Tracker.

Announcements

  • AKS is retiring v1.22.x on December 4th 2022. Please upgrade your clusters to v1.23 and above.
  • Some AKS labels are being deprecated with the Kubernetes 1.26 release. Update your AKS labels to the recommended substitutions. See more information on label deprecations and how to update your labels in the Use labels in an AKS cluster documentation. beta.kubernetes.io/arch= and beta.kubernetes.io/os= are still applied by kubelet in kubernetes code.
  • AKS will be enforcing the de-allocated clusters policy which specifies that manually de-allocating clusters renders the cluster out of support. Starting November 1, 2022 clusters with zero nodes will be stopped after 30 days.

Release notes

  • Preview Features
    • Kubernetes version 1.25 has been released in public preview for AKS and is rolling out to all region. We support Kubernetes 1.25.2.
      • Ubuntu 22.04 for AMD and ARM64 architectures will be the default host.
      • Windows Server 2022 will be the default Windows host. Important, old windows 2019 containers will not work on windows server 2022 hosts.
  • Bug Fixes
    • Updated the AKS WS2022 images with 2022.10C. This update addresses an issue that causes Host Network Service to stop working, creating traffic interruptions. This fix will also be included in the AKS Windows2019 images with 2022.11B. Please see the release notes in https://github.com/Azure/AgentBaker/pull/2380 .
  • Behavior Changes
    • AKS plans to disable "JobTrackingWithFinalizers" APISever feature for k8s version "1.23" in all regions. There is a bug in this feature. 1.23 by default turned on the feature and 1.24+ turned it off.
    • The fields Cloud, Environment, UnderlayClass, and UnderlayName will no longer be available in customers' log analytics workspaces.
    • The container runtime for Ubuntu VHDs now only depends on VHD version, not Kubernetes version. For supported Kubernetes versions < 1.24, this may imply an upgrade. The latest containerd version for all Ubuntu nodes will now be 1.6

Announcements

  • Starting with this release, the pod memory limit for Azure NPM has been increased from 300 MB to 1 GB for clusters with the uptime SLA enabled. Requests will stay at 300 MB.
  • Starting with Kubernetes 1.24, the following changes will be made default:
    • The default format of clusterUser credential for AAD enabled clusters will be ‘exec’, which requires kubelogin binary in the execution PATH. If you are using Azure CLI, it will prompt users to download kubelogin. There will be no behavior change for non-AAD clusters, or AAD clusters whose version is older than 1.24. Existing downloaded kubeconfig will still work. We provide an optional query parameter ‘format’ when getting clusterUser credential to overwrite the default behavior change, you can explicitly specify format to ‘azure’ to get old format kubeconfig.
    • The NodeRestriction Admission Controller will be enabled. This will allow users to enable/disable node restriction.
    • CoreDNS version 1.9.2 will be default version. With this new version of CoreDNS wildcard queries are no longer allowed.
