You can run the container without the "--rm" parameter and then it won't be lost.

If you're not used to docker, to get inside your container again once you exit it.

$ docker ps -a
and you'll see the docker instances that are not running, then just

$ docker start ID_FROM_PS_FIRST_COLUMN
$ docker attach ID_FROM_PS_FIRST_COLUMN

and you're back inside the docker container again.
