This configuration is no longer working and it's outdated.

I tried to run docker-compose but had problems (precisely it couldn't find xdebug, I didn't understand why). Looking at the docker-compose.yml I saw that no versions are specified in the images, so there might be a mismatch between the new versions and older configurations. It would be helpful to update the repository.
