Test all Kubeconfig Contexts

One day I woke up and had like 14 clusters in my Kubeconfig. I didn’t remember which ones did what or if the clusters even still existed.

kubectl config get-contexts -o name | xargs -I {} kubectl --context={} get nodes -o wide

So I cooked up this command to run through them all and make sure they actually responded. This works for me. If you have an alternative way please share in the comments.
