I’ve been writing code professionally for 24 years, 15 of which has been Python and 9 years of that with Docker. I got tired of running into the same complications every time I started a new job, so I wrote this. Maybe you’ll find it useful, or it could even start a conversation, but this post has been a long time coming.
Update: I had a few requests for a demo repo as a companion to this post, so I wrote one today. It includes a very small Django demo user Docker, Compose, and GitLab CI.
Nice. You should check out devcontainers if you haven’t already. Maybe it deviates a little from the dev/prod parity idea, but you can use it with a compose file like you described. It’s saved my current team quite a bit of headache in maintaining local dev environments and keeping everyone in sync as the project evolves.
