Source-backed version compatibility
Kubernetes Version Skew Kubelet version compatibility. Kubelet must not be newer than kube-apiserver and may be up to three minor versions older.
Quick answer
Supported and tested versions have compatibility evidence. Recommended and bundled versions describe upstream choices without establishing compatibility. Versions outside the documented coverage are unknown, not necessarily incompatible.
Supported Kubelet versions
Kubelet must not be newer than kube-apiserver and may be up to three minor versions older.
In HA clusters, this component must satisfy the skew policy for every API server it communicates with; mixed API server versions narrow the allowed range.
