I tried to keep this course "programming language agnostic", meaning that the things you learn would be just as useful with Java as with PHP or Python. But I do get lots of requests for how best to setup a docker project in language X.

Here's some resources for PHP developers.

First, I have my "good defaults" template project here: https://github.com/BretFisher/php-docker-good-defaults

If you're a Laravel developer, they have Laradock, which tries to solve all the docker and docker-compose complexities for PHP developers. The one complaint I get about it, is that it has become quite complex under the hood, but people use it, so give it a shot.
