I'm surprised this is getting so much attention. I thought this just standard practice at this point? If you use things like Gitlab CI then you get this via the `services` in your pipeline. The CI job itself runs in a container too. I use a very similar thing via pytest-docker: https://github.com/avast/pytest-docker https://github.com/avast/pytest-docker The only difference seems to be you declare your containers via a docker-compose file which I prefer because it's a standard thing you can use elsewhere.
