The purpose of /bin/sh in the kubectl exec command is to specify the shell that should be used to execute the command inside the container. When you run a command like:
kubectl exec mypod -- /bin/sh -c "your_command_here"
It tells Kubernetes to start a new shell session in the specified pod and execute the command within that shell. This is useful for running complex commands or scripts that require shell features, such as piping or command substitution.
