Announcements
- With AKS Components Breaking Changes by Version, you can note version changes for components, addons and any breaking changes to be aware of before upgrading versions.
- Kubernetes 1.24 is the last version of Kubernetes supported by AKS Engine. Kubernetes 1.24 goes end-of-life in July, at which point Upstream will stop releasing patches for AKS Engine and archive the project. Please consider using Azure Kubernetes Service (AKS) for managed Kubernetes or Cluster API Provider Azure for self-managed Kubernetes.
- Because of Ubuntu 22.04 FIPS certification status, we'll switch AKS FIPS nodes from 18.04 to 20.04 from 1.27 preview onwards.
- After May 31, 2023, Ubuntu 18.04 will reach end of life. AKS will continue to update the host OS from Canonical into the Kubernetes 1.24 VHD images. Customers will not receive daily security updates from Canonical past the end of May, but will be able to consume those through a node image update only.
- SecurityPatch OS Servicing channel is not supported on Azure Linux when running on NVIDIA GPU enabled VM sizes.
- Windows2019 will be retired in Kubernetes v1.33 and above (ETA March 2026). Customers should upgrade to Windows2022.
- The support policy for clusters in a deleted subscription has been updated. To align with Azure data retention policies, all clusters in a deleted subscription will be deleted immediately. See support policy for more details.
