This is not a perfect Dockerfile, but is a perfect base for anyone willing to run PrivateBin
inside a container. There are a lot of ways to improve it, first being "having configuration
in environment variables".
Anyway, this Dockerfile is great as a basis, and it is possible to "fork" the image and add
our own config file into it.
Another improvement might be "adding a docker-compose.yml full stack, with mysql+bin".
Feel free to do it \o/
