feat: docker image

The new Dockerfile is based on a smaller image (httpd instead of php) and is more secure due to a smaller attack surface. It also comes with a docker-compose configuration and offers some options.

The Dockerfile is using a multi-stage build, and it using the brand new apaxy install script. It is also running as non root so the image can run in a secured container cluster.

+If you want to share files at the root level of your docker container, you'll have to edit the Dockerfile.
