Multiple pod operations

  • Using xargs.
    • Note: xargs
      • The -t option prints each command that will be executed to the terminal.
      • The -p command will print the command to be executed and prompt the user to run it.
      • -I flag. This replaces occurrences of the argument with the argument passed to xargs e.g. -I % 'echo %;echo %'
      • -n 1 , number of parameters to group on command line 
    • kubectl get pods | grep etl | awk -F' ' '{print $1}' | xargs -t kubectl get pod
