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.

    Docker is like, my favorite utility tool, for both deployment AND development (my replacement for Python virtual environments). I wanted to hear more of why I shouldn’t use it also.

      Right? If it’s about ease of insight into containers for debugging and troubleshooting, I can kinda see that. Although I’m so used to working with containers it isn’t a barrier really to me anymore.

        yup. it’s a breeze especially for interpreted langs. mount the source code, expose the ports and voila. need a db?
