copenhagen-a

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

Overview

Location	Copenhagen
OS	Ubuntu 22.04 LTS
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

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

Services

Minecraft

Image	itzg/minecraft-server
Port	25565
Deployment	Docker

Not proxied through Caddy — accessed directly via Tailscale or the host's public 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
• The mariadb Ansible role manages package + secrets; the systemd_services role drops the unit files (ansible/services/mangos-realmd/, ansible/services/mangos-world/)

Other

Service	Port	Deployment	Notes
smartctl_exporter	9633	Docker	Disk SMART metrics scraped by Alloy
node_exporter	9100	Native	Host metrics
systemd_exporter	—	Native	systemd unit metrics
Alloy	—	Native	Ships everything to Grafana Cloud
Tailscale	—	Native	Mesh networking

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 public IP, which is needed for game servers that require direct client connections (WoW realm list, Minecraft server list). The reboot playbook (ansible/playbooks/reboot.yml) does a netplan pre-flight check before rebooting to make sure the static IP config will come back up cleanly.
