Cachix usage

URL: https://pub-solar.cachix.org

Requirements:

Install cachix
Optional: To push to the cache, you need to set CACHIX_AUTH_TOKEN in your environment. To generate one for you, follow the Getting Started docs and login with your GitHub account.
Add our binary cache to your nix config. To add the pub-solar cache, run:

cachix use pub-solar

Example to build and push a custom package of a host in this flake (e.g. after creating an overlay):

nix build --json -f . '.#nixosConfigurations.nachtigall.pkgs.keycloak^*' \
  | jq -r '.[].outputs | to_entries[].value' \
  | cachix push pub-solar

Example to build and push a package in the nixpkgs repo:

cd nixpkgs
nix build --json -f . 'pkgs.lix^*' \
  | jq -r '.[].outputs | to_entries[].value' \
  | cachix push pub-solar

Checking if a package has been correctly pushed to the cache:

❯ nix build --json '/nix/store/f76xi83z4xk9sn6pbh38rh97yvqhb5m0-noto-fonts-color-emoji-png-2.042.drv^*' | jq -r '.[].outputs | to_entries[].value'  | cachix push pub-solar
