attic-action

Cache Nix derivations with Attic.

Usage

Configure your Attic instance with an endpoint, a cache, and a token that can read from and write to the cache. Then, add this step to a workflow job after Nix is installed:

- name: Setup Attic cache
  uses: ryanccn/attic-action@v0
  with:
    endpoint: ${{ secrets.ATTIC_ENDPOINT }}
    cache: ${{ secrets.ATTIC_CACHE }}
    token: ${{ secrets.ATTIC_TOKEN }}

Inputs

endpoint

The Attic endpoint. This is the URL without the cache name.

cache

The name of the Attic cache.

token

The authorization token to provide to Attic (optional).

inputs-from

Path to get the Nixpkgs flake input from instead of github:NixOS/nixpkgs/nixpkgs-unstable when installing Attic (optional).

push-args

Additional command-line arguments to pass to attic push (optional).

skip-push

Disable pushing new derivations to the cache automatically at the end of the job (default is false).

This requires you to invoke attic push <cache> with the paths you want to push to the cache manually.

priority

Nix substituter priority for the Attic cache (optional). When set, the substituter URL in nix.conf will have ?priority=N appended so Nix prefers or deprioritizes this cache relative to others. For example, priority: "30" results in a substituter URL like https://attic.example.com/cache?priority=30.

Outputs

None
