I've used the nixos/nix image from Docker Hub[1] to run some CI scripts using Nix to build my projects.

As far as I understand it, it's basically Alpine Linux with the Nix package manager and tools preinstalled, but it worked pretty well for me.

This is the sort of thing I was looking for. There may not be much too it, (and as another comment mentioned, the package management tools can output containers) but having a blessed starting point shows a clear signal to potential user that it's not just an afterthought.
