Earlier this month I mentioned on Mastodon that I was replacing a Docker-based local development environment at my day job with a Nix-based one, orchestrated with overmind and a justfile.
There was quite a lot of interest in particular in how overmind and just could be used to replace a container / compose-based local development.
While I can’t share the details of the significantly more complex migration I did at my day job (yet!
Some folks on the internet were interested in how I had managed to ditch Docker for local development. This is a slightly overdue write up on how I typically do things now with Nix, Overmind and Just.
I use a similar approach, but I went further by creating a system that compose like docker-compose would. The trick was to write my own nix function mergeShells.

For now, I am pretty happy with it. Also, I put the init script inside nix-shell and not in external files and use exit signal to cleanup the state.
Thanks for sharing this! Added to my weekend inspiration/reading pile. 🙏
