Upgrading a Container Cluster

Whenever a new cluster version is available, the CCE console prompts you to upgrade your container cluster. After a container cluster is upgraded, the Docker version and cluster software of the container cluster are also upgraded, and applications in the container cluster can use new features of CCE.


Your choice of not upgrading container clusters does not affect the existing cluster functions.


All nodes in the container cluster to be upgraded are in the Available state.


  1. On the tab page of the container cluster you will upgrade, choose Operation > Upgrade. Click Click here to upgrade.
