Rename Containerfile, add docker-compose.yml sample

[CovertDuck]

I renamed Containerfile to Dockerfile as it seems to be the standard for Docker.
I also added a basic build_image.sh script as well as a docker-compose.yml sample to get potential new contributors started a little faster.

While Dockerfile is the standard for Docker not everyone runs things through Docker. I prefer Containerfile which is understood by more tooling than just Docker. You can pass -f to Docker to build with a custom file.

The docker-compose.yml is supposed to be called compose.yml and with that change I'd like it in here :)

What is the build_image.sh thing?

Oh! I legitimately did not know that about the Containerfiles/Dockerfiles. Thanks :)

I can rename the docker-compose.yml.

What is the build_image.sh thing?

As for the build script, I usually create one whenever dealing with a Docker container as to not forget some flags. In this simple build_image.sh I simply make sure that our outgoing image is correctly named and version (tagged). I will often use it to inject (into the Containerfile) versionning that can be seen in-app. A Containerfile cannot do that by itself AFAIK.

But this is my way of things, and not necessarily this team's. I will let you decide between nuking it or keeping it and adding to the script as the project grows. :p

I'm fine with those changes as they are now. Thanks! :)

Doesn't the build script require a -f Containerfile flag? It does not work for me without it.

I am not in a place to test that right now but if it doesn't work please open an issue so I can track it :)
