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.
Nix is indeed cool. I just see it as less practical than maintaining a toolchain for devs to use. Seems like reinventing the wheel, instead of airing-up the tires. I could well be absolutely wrong there - my experience is mainly enterprise software and not every process or tool there is used because it is the best one.
I see it as less practical mainly due to the extant tooling and age/maturity of the project.
The ways that I’m most familiar with are use of software like Artifactory - basically a multi-repo. Using such a tool, any package or artifact can be readily retained for future use. Then, for builds, one only needs to ensure that it is used as the package source, regardless of type (PyPy, Docker image, binary, RPM, etc).
Alternatively, one can use individual repos for any relevant package type but that’s a bit more overhead to manage.
@nickwitha_k@uthredii I’d like to think a better analogy would be that nix is like using a 3D model of a wheel instead of a compass and a straightedge to make wheels hehe 🙃

There are definately some things preventing Nix adoption. What are the reasons you see it as less practical than the alternatives?
What are alternative ways of maintaining a toolchain that achieves the same thing?

I quite like the sound of Nix, every time I touch on it but haven’t really dug in yet. You’re making me really want to though.
