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.

    Try to develop on a system that just has node16 3 different projects at the same time that each require different node versions. Nix rocks.

        And now these need different GCC compilers. And building should be easy and reproducible.

          If your app behaves differently based on the GCC version the same node version has been compiled, there’s a fuck-up in there.

            No, I mean my app has a node and an C part, just AS an example. Could also be Java vor PHP.

              ahh, I see. I guess you had to do a bit more work to ensure everything builds with the same versions.
