This topic provides the release notes for the operating system images that are available for Container Service for Kubernetes.
Supported operating systems
For information about the operating systems supported by Container Service for Kubernetes, see Operating systems.
If an operating system version reaches its end of life (EOL), Alibaba Cloud no longer provides technical support for ECS instances that use that version. Alibaba Cloud Linux 2 and CentOS will reach EOL at 00:00:00 on March 31, 2024, and 00:00:00 on June 30, 2024, respectively. To receive fast and efficient technical support and maintain business stability, use Alibaba Cloud Linux 3 or ContainerOS. For more information about the changes and solutions, see [Product Change] Announcement on the end of maintenance for Alibaba Cloud Linux 2 and CentOS 7.
