[FEATURE REQUEST] Docker container install

I wish there was a docker container that i could just pull and run the Server. This would also allow múltiple Server instantes a long with making backup and restore and migrations way easier.

Agreed. Used to maintain some.

I have no interest in creating a Docker install, but if anybody wants to pull request to add a Dockerfile, feel free to do so and I will review it and add it.
