cd examples/interactive-shell $ docker-compose up
In another terminal, but in the same directory you can run one-of commands on the running container:
$ docker exec interactive-shell_one_1 hostname
You can also attach to it:
$ docker attach interactive-shell_one_1
However, when you exit, it will shut down the container.
