Custom overrides, derivations, and other helpful nix expressions.

gh-pages: Where the nix cache is deployed to. Fronted by cloudflare and a cloudflare worker that proxies gitlfs assests.

cg-worker: The cloudflare worker code.

master: Custom overrides, derivations, and other helpful nix expressions.

add channel with raunco alias

nix-channel --add https://nixpkgs.raunco.co/ raunco
nix-channel --update

To enable the cache, the channel must be setup as a substituter. To add in user configuration Add the following to ~/.config/nix/nix.conf(create the file if it doesn't exist) See the nix manual for more information / options such as using extra-substituters

  substituters = https://cache.nixos.org https://nixpkgs.raunco.co/cache
  trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= nixpkgs.raunco.co:bb6Y8BB7fkbRlhaUFzbubClYT5OlHyqEmCG8uh9Kt2U=

If using nix-darwin custom caches can be added for all users via nix.binaryCachePublicKeys and nix.binaryCaches (There is also option nix.trustedBinaryCaches)

Example: darwin-configuration.nix

{ config, lib, pkgs, options, ... }:

# Adds to the list that already contains https://cache.nixos.org
{
  nix.binaryCaches = [
    https://nixpkgs.raunco.co/cache
  ];

  nix.binaryCachePublicKeys = [
    nixpkgs.raunco.co:bb6Y8BB7fkbRlhaUFzbubClYT5OlHyqEmCG8uh9Kt2U=
  ];
}

Using nix-env you can install a package from this channel by running something like nix-env -iA raunco.nodejs-8_x, or install using nix configuration. The example below, uses home-manager

{ ... }:

let
  raunco = import <raunco> {};
in
  {
    home.packages = [
      raunco.vaulted
      raunco.rapture
    ];
  }

You can see the github actions located in .github/workflows/nix.yml. This action should test, build and deploy the cache. Eventually I would like to setup the docker/vagrant local testing with nix expressions!

Tools needed:

• docker
• docker-compose
• vagrant(osx testing)
• virtualbox (used by vagrant)

For now, you can test via docker, docker-compose, and vagrant(for osx)

Example Docker:

# Get into a nix-ubuntu container where you can install / test building / test the channel etc
docker-compose run --rm nix-ubuntu /bin/bash

# Get into a nix container that is closer to nixos
docker-compose run --rm nix /bin/sh

Example Vagrant:

# Start osx machine
vagrant up
