Entering the bash/sh shell in an Kubernetes container can look like this:

kubectl exec -it my-pod --container main-app -- /bin/bash

Or.. You can keep it simple with Kubeshell

> kubeshell
 Pick your pod:
    NAME                                                              READY   STATUS             RESTARTS   AGE
