Support for Docker

Released: Feb 19, 2024

Kubernetes community has removed dockershim from clusters 1.24, in which the Docker container engine is no longer supported. Clusters from v1.27.1-r0 to v1.27.5-r0 and v1.28.1-r0 to v1.28.3-r0 do not allow the creation of nodes using the Docker container engine. However, since there are still users who rely on Docker, CCE will continue to support the creation of nodes that use Docker. In the event that the Docker container engine goes offline, a notification will be sent.

The more lightweight, secure containerd container engine is recommended. If you have containers that use the Docker container engine, you can migrate their container engines to containerd. For details, see Migrating Nodes from Docker to containerd.

For details about the differences between containerd and Docker, see Container Engine.
