Kubernetes can't get bash prompt when exec into pod

Question

I am using Kubernetes to exec into a pod like this:

kubectl exec myPod  bash -i

which works fine, except I don't get a prompt. So then I do:

export PS1="myPrompt "

Which I would expect to give me a prompt, but doesn't. Is there some workaround for this?

Answer 1

Trying to exec into pod in interactive way requires specifying -ti option.

Where -i passes stdin to the container and -t connects your terminal to this stdin.

Take a look at the following example:

kubectl exec -it myPod -- bash
