Because Kubectl Version Skew https://kubernetes.io/docs/setup/version-skew-policy/
If you work with two clusters with at least 2 minor versions apart then there will be functionalities that will be missing. You need to switch your version.
Kubectl-Switch to the rescue
git clone [email protected]:kenichi-shibata/kubectl-switch
go build .
./kubectl-switch
kubectl-switch download # get the latest stable version
kubectl-switch download -k v.1.11.9 # switch to verison v1.11.9
# list available versions
ls ~/.kube/kubectl/
This creates a config file at ~/.kube/kubectl/config if its not created already. Otherwise it will read these values
{
"url_prefix": "https://storage.googleapis.com/kubernetes-release/release",
"version": "v1.14.3"
}
The binares will created in ~/.kube/kubectl/ and the main symlink will be in ~/.kube/kubectl/kubectl which will be symlinked to the active version.
