- Implement complete Vaultwarden deployment using Podman Quadlet
- PostgreSQL backend via Unix socket with 777 permissions
- Caddy reverse proxy with WebSocket support for live sync
- Control-node admin token hashing using argon2 (OWASP preset)
- Idempotent token hashing with deterministic salt generation
- Full Authentik SSO integration following official guide
- SMTP email configuration support (optional)
- Invitation-only user registration by default
- Comprehensive documentation with setup and troubleshooting guides
Technical Details:
- Container: vaultwarden/server:latest from Docker Hub
- Database: PostgreSQL via /var/run/postgresql socket
- Port: 8080 (localhost only, proxied by Caddy)
- Domain: vault.jnss.me
- Admin token: Hashed on control node with argon2id
- SSO: OpenID Connect with offline_access scope support
Role includes automatic argon2 installation on control node if needed.
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.
