The command line environment had a sanctuary where I found peace and happiness away from the world of browser-based tools.

Let’s have a look at two popular ways of opening remote shells: the good ol’ ssh and its modern counterpart, kubectl exec. Below, I will only look at the “kubectl exec” subcommand and its friends. kubectl itself is a swiss-army knife for all things Kubernetes.
