# CI with Gitea Actions

This document covers the Gitea Actions CI workflow for Familienarchiv, including the full workflow YAML, differences from GitHub Actions, and self-hosted runner provisioning.

---

## Self-Hosted Runner Provisioning

Gitea Actions requires self-hosted runners. GitHub Actions provides `ubuntu-latest` for free; on Gitea you run the runner yourself.

```bash
# On the VPS — register a Gitea Actions runner
docker run -d --name gitea-runner --restart unless-stopped -v /var/run/docker.sock:/var/run/docker.sock -v gitea-runner-data:/data -e GITEA_INSTANCE_URL=https://gitea.example.com -e GITEA_RUNNER_REGISTRATION_TOKEN=<token-from-gitea-settings> -e GITEA_RUNNER_NAME=vps-runner-1 -e GITEA_RUNNER_LABELS=ubuntu-latest:docker://node:20-bullseye gitea/act_runner:latest
```

The runner label `ubuntu-latest` maps to the Docker image it uses -- this is how `runs-on: ubuntu-latest` in the workflow YAML continues to work unchanged.

## Gitea vs GitHub Actions Differences

### Context Variable Names

| GitHub Actions | Gitea Actions |
|---|---|
| `github.sha` | `gitea.sha` |
| `github.actor` | `gitea.actor` |
| `github.repository` | `gitea.repository` |
| `github.ref_name` | `gitea.ref_name` |
| `secrets.GITHUB_TOKEN` | `secrets.GITEA_TOKEN` (must be created manually) |

### Token Name Difference

```yaml
# GitHub Actions
password: ${{ secrets.GITHUB_TOKEN }}

# Gitea Actions — use a Gitea access token stored as a secret
password: ${{ secrets.GITEA_TOKEN }}
```

### Container Registry

```yaml
# GitHub Actions — GHCR
registry: ghcr.io
username: ${{ github.actor }}
password: ${{ secrets.GITHUB_TOKEN }}
tags: ghcr.io/${{ github.repository }}/app:${{ github.sha }}

# Gitea Actions — Gitea Package Registry
registry: gitea.example.com
username: ${{ gitea.actor }}
password: ${{ secrets.GITEA_TOKEN }}
tags: gitea.example.com/${{ gitea.repository }}/app:${{ gitea.sha }}
```

## What Works Identically Between GitHub and Gitea Actions

- `uses: actions/checkout@v4` -- works unchanged
- `uses: actions/setup-java@v4` -- works unchanged
- `uses: actions/setup-node@v4` -- works unchanged
- `uses: actions/cache@v4` -- works unchanged
- `uses: docker/build-push-action@v5` -- works unchanged
- `container:` key for running jobs inside a Docker image -- works unchanged
- Secrets syntax `${{ secrets.MY_SECRET }}` -- works unchanged
