Attic build GitHub Action

[Svenum]

Hi,
I like to let you know that I am currently working on an GitHub Action to bild a hole Flake (Packages and nixosConfigurations) to push them to you own Attic instance.

So that you can periodically or on every push build your config and cache the result in your Attic Cache.
As I have not much experience with GitHub Actions I appreciate every help form you guys. 😄

Hi, I have build something similar with https://github.com/jzbor/nix-flake-workflow. Although this is currently mostly for my personal use and may change over time. But feel free to use it as inspiration or with a pinned commit.

my personal approach:

env:
  ATTIC_SERVER: "https://my.attic.com/"
  ATTIC_CACHE: "default"

jobs:
  myjob:
   steps:
    - name: Install Attic and nix-fast-build
      shell: bash
      run: |
        nix profile install nixpkgs#attic-client github:Mic92/nix-fast-build/8e7c9d7

    - name: Configure Attic
      shell: bash
      run: |
        attic login --set-default central "$ATTIC_SERVER" "$ATTIC_TOKEN"
        attic use "$ATTIC_CACHE"

      env:
        ATTIC_TOKEN: ${{ secrets.ATTIC_TOKEN }}

    - name: Build
      shell: bash
      run: |
        nix-fast-build --eval-workers 1 --skip-cached --no-nom --attic-cache=$ATTIC_CACHE \
            -f .#myPackage

        # OR, ALTERNATIVELY:
        
        nix build .#myPackage
        attic push $ATTIC_CACHE result
   

You can package this as a composite action (my example here)

My builder has now reached version 2. with a Docker that can periodically pull an GitHub repo, to build and push the content. https://github.com/Svenum/attic-builder
