You can call APIs to create clusters of other versions. However, these cluster versions will be gradually terminated. For details about the support policy, see the CCE announcement.

NOTE:

  • If not specified, a cluster of the latest version will be created.

  • If a baseline cluster version is specified but the R version is not specified, a cluster of the latest R version will be created by default. It is a good practice not to specify the R version.

When you create a cluster, the latest corresponding platform version is automatically selected.

The format of platformVersion is cce.X.Y.

  • X: internal feature version, indicating changes in features, patches, or OS support in the cluster version. The value starts from 1 and increases monotonically.
