kube-apiserver and kube-proxy

For kube-apiserver and kube-proxy, skew rule is kube-proxy may be up to three minor versions older than kube-apiserver; max skew (minor versions) is 3; may the second component be newer? is no - kube-proxy must not be newer than kube-apiserver; exception for older versions is kube-proxy < 1.25 may only be up to two minor versions older than kube-apiserver; worked example is kube-apiserver is at 1.37 kube-proxy is supported at 1.37, 1.36, 1.35, and 1.34, recorded from its source on 2026-09-01; source re-checked 2026-09-16.

Where each value comes from

This source states these in separate places, so each value is shown with the passage that states it.

Worked example

Example: kube-apiserver is at 1.37 kube-proxy is supported at 1.37, 1.36, 1.35, and 1.34

Newest release when captured

The Kubernetes project maintains release branches for the most recent three minor releases (1.37, 1.36, 1.35).

HA cluster caveat

Note: If version skew exists between kube-apiserver instances in an HA cluster, this narrows the allowed kube-proxy versions.

Upgrade prerequisite

kube-proxy Pre-requisites: The kube-apiserver instances kube-proxy communicates with are at 1.37
