CI Actions

Reusable Forgejo/Gitea actions for toph's infrastructure.

Available Actions

deploy-nix-site (Recommended)

Deploy a static site built with Nix flake to S3 and Nomad. Provides proper isolation and reproducibility.

Requirements:

• Repository must have a flake.nix with a default package output
• Runner label: nix (uses docker://nixos/nix:latest)

Usage:

name: Deploy
on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: nix
    steps:
      - uses: actions/checkout@v4

      - uses: https://git.toph.so/toph/ci-actions/deploy-nix-site@main
        with:
          site-name: mysite
          traefik-rule: Host(`mysite.example.com`)
        env:
          S3_ACCESS_KEY: ${{ secrets.S3_ACCESS_KEY }}
          S3_SECRET_KEY: ${{ secrets.S3_SECRET_KEY }}

Inputs:

• site-name (required): Site identifier
• traefik-rule (required): Traefik routing rule
• flake-output (optional): Nix flake output, defaults to .#
• s3-endpoint (optional): S3 endpoint, defaults to https://s3.toph.so

Example flake.nix:

{
  description = "My static site";

  inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

  outputs = { self, nixpkgs }:
    let
      system = "x86_64-linux";
      pkgs = nixpkgs.legacyPackages.${system};
    in {
      packages.${system}.default = pkgs.stdenv.mkDerivation {
        name = "my-site";
        src = ./.;

        buildInputs = [ pkgs.nodejs_20 ];

        buildPhase = ''
          npm ci
          npm run build
        '';

        installPhase = ''
          cp -r dist $out
        '';
      };

      devShells.${system}.default = pkgs.mkShell {
        packages = [ pkgs.nodejs_20 pkgs.vite ];
        shellHook = "echo 'Run: vite'";
      };
    };
}

deploy-site

Deploy a static site to production via S3 and Nomad (non-Nix).

Usage:

name: Deploy
on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: self-hosted
    steps:
      - uses: actions/checkout@v4

      - name: Build site (if needed)
        run: npm run build

      - name: Deploy
        uses: https://git.toph.so/toph/ci-actions/deploy-site@main
        with:
          site-name: mysite
          traefik-rule: Host(`mysite.example.com`)
          source-dir: dist  # optional, defaults to current dir
        env:
          S3_ACCESS_KEY: ${{ secrets.S3_ACCESS_KEY }}
          S3_SECRET_KEY: ${{ secrets.S3_SECRET_KEY }}

Inputs:

• site-name (required): Site identifier used as Nomad service name
• traefik-rule (required): Traefik routing rule (see examples below)
• source-dir (optional): Directory with built files, defaults to .
• s3-endpoint (optional): S3 endpoint, defaults to https://s3.toph.so

Environment variables:

• S3_ACCESS_KEY: S3 access key (set via Forgejo secrets)
• S3_SECRET_KEY: S3 secret key (set via Forgejo secrets)

What it does:

1. Packages the site directory as a tarball
2. Uploads to S3 at s3://artifacts/<commit-sha>.tar.gz
3. Sets public-read ACL on the artifact
4. Dispatches Nomad job to deploy the site
5. Site becomes available via the specified Traefik rule with Let's Encrypt SSL

Infrastructure handles:

• Docker containers (static-web-server)
• Resource limits (100 CPU, 64MB RAM)
• Traefik routing & Let's Encrypt SSL
• Automatic restarts

Traefik Rule Examples

Single domain:

traefik-rule: Host(`example.com`)

Multiple domains (with www):

traefik-rule: Host(`example.com`) || Host(`www.example.com`)

Subdomain:

traefik-rule: Host(`blog.example.com`)

toph.so domain:

traefik-rule: Host(`mysite.toph.so`)

Path-based routing:

traefik-rule: Host(`example.com`) && PathPrefix(`/docs`)

Setup

1. Deploy S3 service (SeaweedFS)

cd /srv/infra
nix run .#bosun -- run s3

2. Create artifacts bucket

# Configure AWS CLI
export AWS_ACCESS_KEY_ID=<your-access-key>
export AWS_SECRET_ACCESS_KEY=<your-secret-key>
export AWS_ENDPOINT_URL=https://s3.toph.so
export AWS_EC2_METADATA_DISABLED=true

# Create bucket
aws s3 mb s3://artifacts

# Set public-read policy for the bucket
aws s3api put-bucket-acl --bucket artifacts --acl public-read

3. Add Forgejo secrets

In your repository settings (or organization settings for global secrets):

• S3_ACCESS_KEY: The access key from S3 credentials
• S3_SECRET_KEY: The secret key from S3 credentials

That's it! The action will automatically create individual Nomad service jobs for each site.

S3 Access

• API endpoint: https://s3.toph.so
• Console: https://s3-console.toph.so (restricted to Tailscale)
• Credentials: Stored in Nomad variables at nomad/jobs/s3
• Backend: SeaweedFS (S3-compatible)

Troubleshooting

AWS CLI not found

The action automatically installs AWS CLI if not present on the runner.

Access denied during upload

Check that:

1. S3_ACCESS_KEY and S3_SECRET_KEY are set in Forgejo secrets
2. The credentials match those in the S3 Nomad job config
3. S3 service is running: nomad job status s3

Site not accessible

Check:

1. Nomad allocation is running: nomad job status static-site
2. Traefik has picked up the service: check Traefik dashboard
3. DNS resolves: dig <site-name>.toph.so
4. Certificate is valid: curl -v https://<site-name>.toph.so

Development

To add a new action:

mkdir -p new-action
cd new-action
vim action.yaml

Then commit and push to main.
