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 Kubernetes at work and a simpler docker-compose driven setup at home. I find that it’s a tidier way to build infra, but it does have its limits. Abstracting from bare-metal has its ups and downs, but I find the positives outweigh the negatives.

And keep it that way! We need people on both sides to further spur progress. Plus I’m jealous cause I still don’t have a firm grasp on docker.
Fair!
Python, and its need for virtual environments, is what really drove me to master Docker.
