cachix-push

A flake app that can push all buildable flake outputs (determined via devour-flake) to cachix.

Usage

This is a flake-parts module that you can import in your flake.nix and use:

{
  imports = [
    inputs.cachix-push.flakeModule
  ];
  perSystem = { ... }: {
    cachix-push = {
      cacheName = "mycache";
    };
  };
}

Then, run:

nix run .#cachix-push

Tips

• If you use Apple silicon, but want to push the Intel binaries to cache, run: nix run .#cachix-push -- --option system x86_64-darwin.

But why?

While pushing to a Nix cache is best done automatically by CI, there are situations where you want to manually do this. Notably, Github Actions CI doesn't support ARM macOS yet - so to provide a macOS cache to your team, you need to manually push to cachix (or use a different CI service).
