The image starts Jetty, which runs in the background, and then keeps the container on, even if the Rails server (the CMD for the image) stops.
Done when
As a programmer
When running the container in an interactive terminal window, e.g. -it option
And when the Rails server stops
The container also stops
And does not continue to run because jetty is running
So that it can easily be restarted without having to issue an extra docker stop command on the container.
