The docs still described Cloudflare as DNS + CDN in front of helsinki-a, but that was dropped in #90 - pez.sh lives on Hetzner DNS via Terraform now and records point straight at the origin. Updated README, architecture, networking, getting-started and the nuremberg-a host doc to match, and noted that pez.solutions still resolves via Cloudflare outside Terraform. Also fixed while I was in there: - terraform/README: PagerDuty provider is ~> 3.32 (table said ~> 2.2), and the B2 secret keys are backblaze_keyID/backblaze_applicationKey - secrets docs: group_vars secrets file is .enc.yaml, dropped the FreeBSD install steps, the long-gone .sops.yaml placeholder note and the ANSIBLE_VAULT_PASS migration note, swapped the cloudflare_record example for hcloud - getting-started referenced ansible/scripts/sops-setup.sh which doesn't exist - added naveen.pez.sh to the subdomain tables and a note about the DNS-only records (mail, minecraft, wow, public)

helsinki-a
Public-facing traffic gateway. Everything exposed to the internet goes through this box.
Overview
| Location | Hetzner Cloud (Helsinki) |
| OS | Debian 13 (Trixie) |
| Tailscale IP | 100.67.6.27 |
| Role | Reverse proxy, SSO, Bitwarden, Forgejo |
| Provider | Hetzner Cloud VPS |
What it does
This is the front door. All public subdomains under pez.sh and pez.solutions terminate here via Caddy, which proxies traffic to the appropriate backend over Tailscale.
It also runs the auth stack — Authelia for SSO and LLDAP as Authelia's user backend. Having auth on the same box as the proxy keeps latency low for the forward_auth check.
Bitwarden (Vaultwarden) and Forgejo also live here. Both expose their own login and don't go through Authelia. Bitwarden is on helsinki-a for availability — password management needs to be reachable even if the London servers are having a moment. Forgejo is colocated for the same reason and to keep Git access independent of home internet.
Services
| Service | Port | Deployment | Notes |
|---|---|---|---|
| Caddy | 80, 443 | Native (apt + systemd) | Reverse proxy + TLS termination. Config at /etc/caddy/Caddyfile |
| Authelia | 9091 | Docker | SSO, accessible at auth.pez.sh |
| Authelia MariaDB | (internal) | Docker | Authelia session/state |
| LLDAP | 3890, 17170 | Docker | User directory for Authelia (UI at ldap.pez.sh) |
| Bitwarden (Vaultwarden) | 8443, 8080 | Docker | bitwarden.pez.sh, own auth |
| Bitwarden MariaDB | (internal) | Docker | Backing DB |
| Forgejo | 3000 (HTTP), 2222 (SSH) | Docker | git.pez.sh, own auth; SSH on git.pez.sh:2222 |
Caddy is the only service installed natively — it needs to bind 80/443 directly and there's no benefit to wrapping it in Docker on a single-purpose proxy host. Everything else runs as Docker Compose stacks under /opt/docker/<service>/ (managed by the docker_services Ansible role from ansible/services/<service>/docker-compose.yml).
Static sites
Caddy also serves static content from /srv/:

naveen.pez.sh | — |
Why Hetzner Cloud
Public-facing services need a stable public IP and good uptime. Residential IPs are dynamic and unreliable for this purpose. Hetzner Cloud is cheap, reliable, and has good European connectivity.
