kubectl exec --help

Execute a command in a container.

Examples:
  # Get output from running the 'date' command from pod mypod, using the first container by default
  kubectl exec mypod -- date

  # Get output from running the 'date' command in ruby-container from pod mypod
  kubectl exec mypod -c ruby-container -- date

  # Switch to raw terminal mode; sends stdin to 'bash' in ruby-container from pod mypod
  # and sends stdout/stderr from 'bash' back to the client
  kubectl exec mypod -c ruby-container -i -t -- bash -il

  # List contents of /usr from the first container of pod mypod and sort by modification time
  # If the command you want to execute in the pod has any flags in common (e.g. -i),
  # you must use two dashes (--) to separate your command's flags/arguments
  # Also note, do not surround your command and its flags/arguments with quotes
  # unless that is how you would execute it normally (i.e., do ls -t /usr, not "ls -t /usr")
  kubectl exec mypod -i -t -- ls -t /usr

  # Get output from running 'date' command from the first pod of the deployment mydeployment, using
the first container by default
  kubectl exec deploy/mydeployment -- date

  # Get output from running 'date' command from the first pod of the service myservice, using the
first container by default
  kubectl exec svc/myservice -- date

    --pod-running-timeout=1m0s:
