Kubernetes Version Policy

CCE provides highly scalable, high-performance, enterprise-class Kubernetes clusters. As the Kubernetes community periodically releases Kubernetes versions, CCE will release cluster Open Beta Test (OBT) and commercially used versions accordingly. This section describes the Kubernetes version policy of CCE clusters.

The CCE console supports clusters of the latest two commercially used versions:

  • a: Clusters created using the console or APIs
  • b: Clusters created only using APIs

Phases of CCE Cluster Versions

  • OBT: You can experience the latest features of this cluster version. However, the stability of clusters of this version has not been completely verified, and the Service Level Agreement (SLA) of CCE is not valid for such clusters.
  • In commercial use: The cluster version has been fully verified and is stable and reliable. You can use clusters of this version in the production environment, and the CCE SLA is valid for such clusters.
  • EOS: After the cluster version EOS, CCE does not support the creation of new clusters or provide technical support including new feature updates, vulnerability or issue fixes, new patches, work order guidance, and online checks for the EOS cluster version. The CCE SLA is not valid for such clusters.

CCE Cluster Versions

CCE clusters are updated according to the versions available in the Kubernetes community. This means that a CCE cluster version is made up of both the Kubernetes community version number and the CCE patch version number. The CCE cluster version is in the format of vX.Y.Z-rN, such as v1.28.2-r0.

Cluster Upgrade

Periodically upgrade CCE clusters for better user experience. Using an EOS version, you cannot obtain technical support and CCE SLA assurance. Upgrade CCE clusters in a timely manner.

On the CCE console, you can easily upgrade clusters in a visualized manner, improving the stability and reliability of clusters.
