Announcements

  • No new clusters can be created with Azure AD Integration (legacy). Existing AKS clusters with Azure Active Directory integration will keep working. All Azure AD Integration (legacy) AKS clusters will be migrated to AKS-managed Azure AD automatically starting from 1st Dec. 2023. We recommend updating your cluster with AKS-managed Azure AD before 1 Dec 2023. This way you can manage the API server downtime during non-business hours.
  • Please review the following CVEs that impact all Windows node pools in AKS clusters - CVE-2023-3676, CVE-2023-3955, and CVE-2023-3893. Please update your Windows nodes to the VHD version 230809 as mentioned in these issues.
  • To avoid disruptions stemming from unmanaged Canonical nightly security updates, AKS will disable unmanaged Canonical nightly updates by 2 September 2023
    on clusters that haven’t specified an update option explicitly, mapping to the option None in the node OS upgrade channel feature. AKS strongly recommends proactively moving to auto-upgrade node-image or node OS upgrade channel - Security Patch; you can set maintenance windows for these channels.

Release notes

  • Behavioral changes

    • Previously AKS returned only 1 random node's failure even if multiple nodes had drain failures, in the error response. Now all the node drain failures are appended to the error response and returned for easier troubleshooting.

  • Bug Fixes

    • Customers using Azure Monitor Managed Prometheus Service for AKS Clusters may have experienced issues with metrics add-on being disabled, missing metrics and alerts, in case both Container Insights log and Managed Prometheus are enabled on the clusters. These hotfixes fix that issue.
    • A bug was fixed that prevented clusters using Azure CNI Powered by Cilium from starting after being stopped.

  • Component Updates
