Example docker-compose.yml + Explanations

[bioluks]

Hi,

Title says it all. It can be hard for many newbies to self-host their containers. A basic ready to launch docker-compose could increase the general usage of mumble. Tried to be neutral as possible in the compose file.

Thanks for your PR and sorry for the super late response. We already have https://github.com/mumble-voip/mumble-docker/wiki/docker_example_mumble_mumo_postgres and I think any improvements to that and/or further usage documentation should go into the wiki as well.

The wiki should have this as well, but wouldn't it be also good to additionally keep the file called as docker-compose.example.yml in the git root? I can make changes there also, it seems pretty outdated.

I would say it should be either or. Otherwise we only have code duplication that will lead to the versions becoming out of sync. But maybe the wiki could be advertised more prominently in the README?
