Supported Kubernetes Versions

Linkerd supports all versions of Kubernetes that were supported at the time that a given Linkerd version ships. For example, at the time that Linkerd stable-2.14.0 shipped, Kubernetes versions 1.26, 1.27, and 1.28 were supported, so Linkerd stable-2.14.0 supports all of those Kubernetes versions. (In many cases, as you’ll see below, Linkerd versions will also support older Kubernetes versions.)

Obviously, Linkerd stable-2.14.0 has no knowledge of what changes will come after Kubernetes 1.28. In some cases, later versions of Kubernetes end up making changes that cause older versions of Linkerd to not work: we will update the chart below as these situations arise.

Notes:

1. Linkerd will almost never change the supported Kubernetes version in a minor release, which is why the table above only lists major versions. One known exception: Linkerd 2.11.0 supported Kubernetes 1.16, but 2.11.1 and later required Kubernetes 1.17 as shown in the table above.
