## Backup

### What to Backup
1. **PostgreSQL database**: `gitea` database
2. **Repository data**: `/var/lib/gitea/data/gitea-repositories`
3. **Configuration**: `/etc/gitea/app.ini`
4. **Custom files**: `/var/lib/gitea/custom` (if any)

### Backup Commands
```bash
# Database dump
sudo -u postgres pg_dump gitea > gitea-backup-$(date +%Y%m%d).sql

# Full data directory
tar -czf gitea-data-$(date +%Y%m%d).tar.gz /var/lib/gitea

# Config only
cp /etc/gitea/app.ini gitea-app-$(date +%Y%m%d).ini
```

### Restore
```bash
# Restore database
sudo -u postgres psql -d gitea < gitea-backup.sql

# Restore data
tar -xzf gitea-data.tar.gz -C /
chown -R git:git /var/lib/gitea
```

## Upgrades

### Upgrade Gitea
```bash
# Stop service
systemctl stop gitea

# Backup current binary
cp /usr/local/bin/gitea /usr/local/bin/gitea.backup

# Download new version
wget -O /usr/local/bin/gitea https://dl.gitea.com/gitea/VERSION/gitea-VERSION-linux-amd64

# Set permissions
chmod +x /usr/local/bin/gitea

# Start service (will auto-migrate database)
systemctl start gitea

# Check logs
journalctl -u gitea -f
```

### Check Version
```bash
/usr/local/bin/gitea --version
```

## Setting Up CI/CD with Gitea Actions

Gitea Actions are enabled and ready to use. To set up a runner:

### Option 1: Docker Runner (Recommended)
Since the LXC has nesting enabled, you can run a Docker-based Actions runner:

```bash
# Install Docker in the LXC
curl -fsSL https://get.docker.com | sh

# Run Gitea Actions runner
docker run -d \
  --name gitea-runner \
  --restart unless-stopped \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -e GITEA_INSTANCE_URL=https://git.manticorum.com \
  -e GITEA_RUNNER_REGISTRATION_TOKEN=<token-from-gitea-admin> \
  gitea/act_runner:latest
```

### Option 2: Separate Runner LXC
Create a dedicated LXC for running Actions with more isolation.

### Using Actions
Create `.gitea/workflows/main.yml` in your repository:

```yaml
name: CI
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Run tests
        run: |
          npm install
          npm test          
```

## Adding Repositories

### Via Web UI
1. Go to https://git.manticorum.com
2. Click "+" → "New Repository"
3. Fill in details and create

### Via Command Line
```bash
# Add remote
git remote add homelab git@git.manticorum.com:cal/repo-name.git

# Or HTTPS
git remote add homelab https://git.manticorum.com/cal/repo-name.git

# Push
git push homelab main
```

### Migrate from GitHub
Gitea has built-in migration:
1. New Repository → "Migrate from GitHub"
2. Enter GitHub URL and token
3. Gitea will clone all commits, branches, tags

## Integration with NPM

Reverse proxy is configured on NPM (10.10.0.16):
- **Domain**: git.manticorum.com
- **Forward to**: 10.10.0.225:3000
- **SSL**: Let's Encrypt
- **Websockets**: Enabled

## Troubleshooting

### Gitea won't start
```bash
# Check logs
journalctl -u gitea -n 50

# Common issues:
# - Permission on /etc/gitea/app.ini (should be 640, root:git)
# - PostgreSQL not running
# - Port 3000 already in use
```

### Can't connect to database
```bash
# Check PostgreSQL is running
systemctl status postgresql

# Test connection
PGPASSWORD=gitea123 psql -U gitea -d gitea -h 127.0.0.1 -c "SELECT 1;"

# Check pg_hba.conf allows md5 auth
cat /etc/postgresql/12/main/pg_hba.conf | grep md5
```

### 502 Bad Gateway on web
```bash
# Check Gitea is listening
ss -tlnp | grep 3000

# Check NPM can reach container
curl http://10.10.0.225:3000

# Verify firewall rules (should allow from 10.10.0.0/24)
```

### Actions runner not working
- Ensure runner is registered in Gitea Admin → Actions → Runners
- Check runner logs: `docker logs gitea-runner`
- Verify GITEA_INSTANCE_URL is correct
- Ensure runner has network access to Gitea

## Security Notes

- Database password is stored in `/etc/gitea/app.ini` (secured with 640 permissions)
- SSH keys for Git access are stored per-user in Gitea database
- JWT secrets are auto-generated and stored in config
- LXC is unprivileged for better isolation
- PostgreSQL only listens on localhost
