Overview
supports multiple Kubernetes versions across different releases. Understanding the supported versions is essential for:
- Creating clusters – Determine which Kubernetes versions can be used when provisioning new clusters
- Upgrading – Ensure all workload clusters meet compatibility requirements before upgrading the global cluster
- Managing third-party clusters – Verify that public cloud or CNCF-compliant Kubernetes clusters are within the supported version range
Version Support Matrix
The following table shows the Kubernetes version support for each release.
The table lists minor versions and does not distinguish between patch versions. Patch versions only include bug fixes and security updates, so the Kubernetes minor versions remain consistent across all patch versions within the same minor release.
Starting from 4.1, each release supports only one Kubernetes version for cluster creation. This ensures consistency and simplifies the upgrade path for new clusters.
Upgrade Requirements
For 4.2 and earlier, all workload clusters must be upgraded to the latest Kubernetes version in the compatible versions list before upgrading the global cluster.
In future releases, workload clusters will only need to be within the compatible versions range to upgrade the global cluster.
