Add docker compose

[RCM7]

Basically I added the docker-compose I usually use to spin up my game server.

This way all the mounts, port mapping, environment variables and build step is handled by docker-compose and specified in this file, reducing the size of the commands to something like:

docker-compose up -d
docker-compose down
docker-compose build

Any doubts just ask, but don't skip a look at the docker-compose documentation if you don't understand something.

Cheers

@zopanix The Travis-CI build is failing because the environment variables haven't been configured in travis. Can you set that up please?

[zopanix]

Hey, the env vars are set, it should work now

[RCM7]

I don't believe using Travis CI is the best tool to build images automatically and put them in Docker Hub since Docker Hub themselves support github integration and automatic builds of images...

So unless Travis CI is running some tests on the image, I don't think it should be used at all.

[bkuhl]

The value Travis-CI adds over Dockerhub is that it can tag the images in accordance with the GitHub release version number. Dockerhub isn't capable of this kind of integration.

[RCM7]

Beg to disagree. It is possible and they even show you how with examples in the page where you set it up

EDIT:

[bkuhl]

You're totally right, I don't remember seeing this. This could replace the travis integration. The full docs are here: https://docs.docker.com/docker-hub/github/

@RCM7 @bkuhl : I already tried using docker build tools but it didn't work that well. I don't have as many options as you show on your screenshot and, while everything is configured correctly, I've never seen an automated build starting on its own. That's why I've chosen travis ci to manage this.
It might I don't get how it works :p

[RCM7]

@zopanix I understand that. I tried to reproduce the steps in a dummy project, and while some may seem confusing, it all checked out and it works. If you'd give it a try I'm glad to help with anything :)

[RCM7]

Ping 😄

[bkuhl]

Upgrading this would be on @zopanix unless he wants to give me access to the Dockerhub repo as well.

[zopanix]

Hey, sorry I've been inactive bud I'm getting installed in my new home. I moved to canada from France it will take me a week or two to be completely operationnal :)

I suggest to remove the default network and overridden environment variables.

[psykzz]

No need to specify a network as one is automatically created with bridge type.

[psykzz]

Defaults for the environment are already provided in the Dockerfile, is there a need to redefine them?

[RCM7]

Sorry for the delay, I was out in vacation and then too occupied catching up with work 😄
