Major Changes:
- Add dual SSH mode system (passthrough default, dedicated fallback)
- Refactor domain configuration to use direct specification pattern
- Fix critical fail2ban security gap in dedicated mode
- Separate HTTP and SSH domains for cleaner Git URLs
- Restructure security playbook with modular nftables loader
- Base rules loaded first, service rules second, drop rule last
- Add Gitea self-contained firewall management (port 2222)
- Add fail2ban protection for Gitea SSH brute force attacks
- Update documentation with new firewall architecture
- Create comprehensive Gitea deployment and testing guide
This enables self-contained service roles to manage their own firewall
rules without modifying the central security playbook. Each service
deploys rules to /etc/nftables.d/ which are loaded before the final
drop rule, maintaining the defense-in-depth security model.
- Implements complete Gitea Git service following rick-infra self-contained architecture
- Uses PostgreSQL infrastructure role as dependency and manages own database/user
- Native Arch Linux installation via pacman packages
- Automatic database setup (gitea database and user creation)
- SystemD service with security hardening and proper dependency management
- Caddy reverse proxy integration deployed to sites-enabled directory
- SSH server on port 2222 with automatic host key generation
- Production-ready with LFS support, security headers, and HTTPS via Caddy
- Follows simplified configuration approach with essential variables only
- Self-contained pattern: service manages complete setup independently
