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
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
Pushing 1 paths (0 are already present) using zstd to cache pub-solar ⏳
