Support for Docker

Released: Feb 19, 2024

Kubernetes community has removed dockershim from clusters v1.24, in which the Docker container runtimes are no longer supported. Clusters from v1.27.1-r0 to v1.27.5-r0 or v1.28.1-r0 to v1.28.3-r0 do not allow the creation of nodes using the Docker container runtimes. 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 runtimes go offline, a notification will be sent.

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

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