Docker image and docker-compose.yml

Would be nice to have a Docker image and docker-compose.yml file.

There are dozens of packaging systems now and I simply don't have the time to learn them all (or indeed, any of them). If anyone with the right skills wants to create a new packager, I would be happy to add it to the semi-official list. I would also be happy to add a docker-compose.yml file to the source code, if someone succeeds in creating one. (Looks like some limited progress was made a couple of years ago.)
