Hi Folks, Rancher desktop is using set my Kubectl version to latest 1.26. But currently most of my K8s clusters are running in 1.19 and its giving few warning while running Kubectl command with old cluster.

-> kubectx
I0413 15:29:59.844450   64080 versioner.go:56] Remote kubernetes server unreachable
I0413 15:30:05.131215   64088 versioner.go:56] Remote kubernetes server unreachable

how can I set my kubectl version to 1.21 or similar

ls -la /usr/local/bin/kubectl
lrwxr-xr-x  1 root  admin  55 Nov 11 11:08 /usr/local/bin/kubectl -> /Applications/Docker.app/Contents/Resources/bin/kubectl

Hi @better-wolf-9235! Thank you for re-posting your message here 🙂 Just to be sure I understand your question correctly. Do you want to downgrade your configured kubectl version in Rancher Desktop?

Nope I want to stop warning messages we are getting while access or switching to any of my in house clusters

The warning message you are referring to is

Remote kubernetes server unreachable

, right?

Hi @better-wolf-9235, could check if you have multiple contexts inside

~/.kube/config

file?

kubectl config get-contexts

@clever-mouse-42560 Yes I have around 12 K8s clusters in my config file and all are accessible.

Ok, did you switch to the right context when you use the other clusters?

kubectl config use-context your-context

Ye we are using

kubectx

to switch between clusters

ok

one more thing in Rancher desktop I haven't enable Kubernetes settings. its uncheck along with enable Traefik

@better-wolf-9235 Did you ever enable Kubernetes in Rancher Desktop? Is there a version listed in the drop down? I haven't experienced this particular problem, but I don't have clusters running on that old a version of k8s.

you need to select a kubernetes version within the version skew policy https://kubernetes.io/releases/version-skew-policy/ (that shows latest version numbers, but same concept applies)
