Supported Kubernetes Versions¶

In DCE 5.0, the integrated clusters and created clusters have different version support mechanisms.

This page focuses on the version support mechanism for created clusters.

The Kubernetes community supports three version ranges: 1.26, 1.27, and 1.28. When a new version is released by the community, the supported version range is incremented. For example, if the latest version released by the community is 1.27, the supported version range by the community will be 1.27, 1.28, and 1.29.

To ensure the security and stability of the clusters, when creating clusters in DCE 5.0, the supported version range will always be one version lower than the community's version.

For instance, if the Kubernetes community supports v1.25, v1.26, and v1.27, then the version range for creating worker clusters in DCE 5.0 will be v1.24, v1.25, and v1.26. Additionally, a stable version, such as 1.24.7, will be recommended to users.

Furthermore, the version range for creating worker clusters in DCE 5.0 will remain highly synchronized with the community. When the community version increases incrementally, the version range for creating worker clusters in DCE 5.0 will also increase by one version.
