This topic describes the release notes for the OS images supported by Container Service for Kubernetes.
Usage notes
If an operating system version is announced the end of life (EOL), Alibaba Cloud stops technical support for Elastic Compute Service (ECS) instances that run on the operating system version. Alibaba Cloud Linux 2 is discontinued since 0:00:00 on March 31, 2024. CentOS will be discontinued from 0:00:00 on June 30, 2024. To quickly obtain technical support and ensure business continuity and stability, we commend that you use Alibaba Cloud Linux 3 or ContainerOS. For more information about the changes and solutions, see [Product Changes] Alibaba Cloud Linux 2 and CentOS 7 are discontinued.
Container Service for Kubernetes allows you to create nodes that run Alibaba Cloud Linux 3.
