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

# 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

# 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

# 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

/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:

# 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:

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

# 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

# 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

# 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

# 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
