You can create clusters of two latest versions on the CCE console. To learn which cluster versions are available, log in to the CCE console, create a cluster, and check the Cluster Version parameter. 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.

platformVersion

String

CCE cluster platform version, indicating the internal version under the cluster version (version). Platform versions are used to trace iterations in a major cluster version. They are unique within a major cluster version and recounted when the major cluster version changes. This parameter cannot be customized. 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.
  • Y: patch version of an internal feature version. It is used only for software package update after the feature version is brought online. No other modification is involved. The value starts from 0 and increases monotonically.
