Description (last modified by Tom Forbes)

As per a discussion on the developers mailing list, I would like to propose adding docker-compose support to Django.

Right now running the test suite across different databases is annoying at best, and is a pain point for new developers wishing to join the project. With a relatively small number of changes we can add a docker-compose definition to the Django project itself which will allow anyone to quickly run tests across any supported Python/database version.

One option is to add this to runtests.py, i.e runtests.py --docker. I do not think this is a good approach as there are a large ecosystem of tools that already work with docker, including editors, CLI tools and shells, which will not work with runtests.py.

I've already done most of the work for this in django-docker-box. We would need to copy the docker-compose.yml file as well as the Dockerfile, and add documentation.

Getting this to work with Oracle would require more work and I believe it can be done as a future ticket.

In django-docker-box I've had to create specific settings files for each backend. I can't see a way around not including this in core as well, perhaps under a tests/settings/docker/ subdirectory?

Accepting on the basis that I've used Tom's django-docker-box extensively since I learned about it and it greatly simplified my testing setup.

I assume it would help speeding up initial contributor setup as well.

I'm marking this Patch needs improvement since there are comments/issues on the PR and in the django-docker-box repo.

There's an ongoing discussion thread on django-docker-box which seems to be home to the conversation currently.

FYI, there is an official Docker image for Oracle now. I added it to the wiki too, seealso: https://code.djangoproject.com/wiki/OracleTestSetup
