| # GitHub Actions workflow to automate updating the Nix flake.lock file | |
| # Triggered manually or every 4 hours via cron schedule | |
| # Steps: | |
| # 1. **SSH Agent Setup**: Uses `webfactory/ssh-agent` to set up SSH access with deploy keys (ensure the deploy key is added to the repository settings) | |
| # 2. **Checkout Repository**: Checks out the repository using `actions/checkout` | |
| # 3. **Install Nix**: Installs Nix with `DeterminateSystems/nix-installer-action` | |
| # 4. **Update flake.lock**: Updates the `flake.lock` file using `DeterminateSystems/update-flake-lock`, creating or updating a pull request with specified commit message, PR body, title, and labels | |
| # 5. **Create Compare URLs**: If a pull request is created or updated, runs a script using `actions/github-script` to add a comment with compare URLs | |
| # Notes: | |
| # - Secrets (`secrets.GH_ACTIONS` and `secrets.TESTING`) are used for authentication | |
| # - `nix-options` includes the GitHub token for accessing private repositories | |
