hello world
    pod "dummy" deleted
    ```

    As you observe, sending _world_ on a TCP connection to the server results in
    the server prepending _hello_ and echoing back with _hello world_.

1. To clean up, execute the following command:

    ```console
    $ kubectl delete -f tcp-echo.yaml
    service "tcp-echo" deleted
