Container Service for Kubernetes OS image release notes-Container Service for Kubernetes(ACK)-阿里云帮助中心

Covers OS image versions and kernel updates for Container Service for Kubernetes cluster nodes.

Supported operating systems

See Operating systems for the OS images supported by Container Service for Kubernetes.

Important

If an OS version reaches end of life (EOL), Alibaba Cloud no longer provides technical support for ECS instances running that version. Alibaba Cloud Linux 2 reached EOL at 00:00:00 on March 31, 2024, and CentOS at 00:00:00 on June 30, 2024. For continued support, we recommend migrating to Alibaba Cloud Linux 3 or ContainerOS. See [Product change] Announcement on ending maintenance for Alibaba Cloud Linux 2 and CentOS 7.
