copenhagen-a: document all live services in host_vars and docs (#30 )

Audit of copenhagen-a found several running services not captured in
host_vars: cloudflared, node_exporter (systemd), and MariaDB. Also
found postgresql and redis running with no active consumers.

Updated host_vars to list all services and added undocumented_services
for the potentially unused ones. Updated docs with cloudflare tunnel,
monitoring, and notes about stale Docker images to clean up.

Closes PESO-100

Raw Blame History

copenhagen-a

Game servers. Located at my dad's place in Copenhagen as an off-site location.

Overview


Location	Copenhagen
OS	Ubuntu 22.04
Tailscale IP	100.89.206.60
Role	Gaming servers (Minecraft, WoW)
Form factor	Lenovo "tiny" desktop (lunchbox-sized)

Hardware

Component	Spec
CPU	Intel i5-4570T (4 threads)
Memory	16 GB
Boot disk	500 GB (26% used)

Compact Lenovo desktop — powered by a standard ThinkPad charging brick. Small, quiet, and draws minimal power.

Services

Minecraft


Image	`marctv/minecraft-papermc-server`
Port	25565
Deployment	Docker

PaperMC for better performance than vanilla. Not proxied through Caddy — accessed directly via Tailscale or the host's IP.

World of Warcraft (MaNGOS Zero)

WoW 1.12 (Vanilla) private server using the MaNGOS Zero emulator. Runs natively — not in Docker.

Service	Port	Managed by
mangos-realmd	3724	systemd
mangos-world	8085	systemd
MariaDB	3306	systemd (apt-managed)

Runs as the mangos user
Install path: /home/mangos/mangos/zero/
MariaDB hosts the character, world, and auth databases locally

Both mangos-realmd and mangos-world start automatically on boot via systemd.

Cloudflare Tunnel


Binary	`/usr/bin/cloudflared`
Managed by	systemd
Unit file	`ansible/services/systemd/copenhagen-a/cloudflared.service`

Provides Cloudflare Tunnel access to the host. Token-based authentication configured directly in the systemd unit.

Monitoring

Service	Port	Managed by
node_exporter	9100	systemd (Ansible-managed)

Prometheus Node Exporter for host metrics. Installed and managed via the Ansible node_exporter role. Scraped by Prometheus on london-a via Tailscale.

Note: Stale Docker images for prom/node-exporter and quay.io/prometheus/node-exporter exist on the host from a previous Docker-based deployment. These should be cleaned up — the systemd service is the active one.

Potentially Unused Services

The following services are running but have no known active consumers:

Service	Notes
PostgreSQL 14	Only default databases (template0, template1, postgres). Likely leftover.
Redis 6.0	Running but no known application depends on it.

These are candidates for removal or investigation.

Networking

Connected directly to the ISP router's built-in switch. Symmetrical 500 Mbit connection — more than enough for game servers.

Notes

Copenhagen-a has a static IP, which is needed for game servers that require direct client connections (WoW realm list, Minecraft server list).
