<p>I just upgraded kubernetes cluster, but kubectl is very inconsistent in showing me the version. How can I verify this. Any source of truth?</p>

<pre><code>[iahmad@web-prod-ijaz001 k8s-test]$ kubectl  version
Client Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.3", GitCommit:"5e53fd6bc17c0dec8434817e69b04a25d8ae0ff0", GitTreeState:"clean", BuildDate:"2019-06-06T01:44:30Z", GoVersion:"go1.12.5", Compiler:"gc", Platform:"linux/amd64"}

<p>IIRC: <code>kubectl version</code> is telling you what version the APIServer is at (1.14.3). <code>kubectl get nodes</code> is telling you what version the <code>kubelet</code> is on those nodes.</p>
