feat(docker): add pipeline and docker support

[Helias]

What the two gh workflows do?

• docker.yml: build a docker image through the Dockerfile and push the image as "package" in your profile/organization, example: https://github.com/Helias/www-aowow/pkgs/container/www-aowow
• e2e-test-setup.yml: runs the setup inside an ubuntu 24.04 container using github action and generate some screenshots of the applications, then these screenshots are attached as artifacts in the workflow results. Thanks to these screenshots anyone can check the output of the application example: https://github.com/Helias/www-aowow/actions/runs/14070787499

The e2e-test-setup is not a real e2e tests, because it does not make any assertion, it verifies partially the setup (specifically it runs php aowow --sql and php aowow --build). It's a fast way to verify the output of it, without building all the full application locally. I would like to ask you @Sarjuuk some feedback about which screenshots we could generate to verify the major AoWoW functionalities, in terms of NPCs, zones, objects and any entity we could select for this.

Note: as written in the README the wow images and mpqdata are not involved during the setup (only DBCs are), so all the images will not be present.

How to test docker

docker pull ghcr.io/helias/www-aowow:docker-setup
docker run --name aowo-docker -p 80:80 ghcr.io/helias/www-aowow:docker-setup

Could you please explain, why did you decided to put few services into one container ?
Is not better to separate them as independent to each other, and then join in docker-compose.yaml configuration ?

Dockerfile should contain configuration(-s) only for concrete service(-s) — in this case only for web-application (php); other containers (like web-server (nginx/apache-httpd) or database (mysql/mariadb/etc)) should be moved outside. Services should be connected through ports, common environment, etc.

For example, what if i want to run this web-application, but use existing database server, how i have to manage to do that ?

I agree, I should do one container per service.
This was more a PoC, can be surely improved
