How to give the input for the kubectl command?

Actually I am trying to make the following command in one command

kubectl get pods| grep -oP 'mag[^\s]+'

output
mag121111

After that I will run the following command

kubectl exec -itmag121111 bash

Now I am trying as following 

 kubectl get pods| grep -oP 'mag[^\s]+' | kubectl exec -it bash

This works for me

kubectl exec -it $(kubectl get pods| grep -oP 'mag[^\s]+') --container magname -- /bin/bash

here magname is actual pod name

kubectl exec -it $(kubectl get pods| grep -oP 'mag[^\s]+') --/bin/bash

OR

kubectl exec -it $(kubectl get pods| grep -oP 'mag[^\s]+') --bash

You can use kube-fzf. It makes exec into a pod(container) and portforward super easy.

Refer this for execpod
