Homelab Infrastructure

A peek under the hood of my homelab. Proxmox, Synology, Docker, and how everything is wired together.

{% include "card-grid.njk" %}

The setup at a glance

The infrastructure runs on three physical machines: a Beelink S12 Pro running Proxmox as the primary host, a second Beelink running Proxmox as a test host, and a Synology DS918+ NAS for storage and Docker services. Development runs in a Xubuntu VM on the Proxmox hosts. An OpenWrt router handles multi-WAN failover with WiFi and Powerline backhaul, and four Zyxel GS1200-8HP managed switches distribute the network across the flat.

The whole stack is monitored via Prometheus and Grafana, with node exporters on every machine, cAdvisor for container metrics, and SNMP exporters for network hardware. Backups follow a layered strategy: local snapshots, NAS copies, offsite sync to a Raspberry Pi in a different room, and cloud archive for worst-case scenarios.

Why Proxmox

Proxmox VE was chosen over alternatives like ESXi or plain Docker for several reasons. The open-source model means no licensing headaches. LXC containers provide near-native performance for lightweight services without the overhead of full VMs. The web UI makes it easy to manage snapshots, backups, and migrations. And the ZFS support on the underlying Debian system gives us reliable snapshots and send/receive for the backup chain.

How services are organized

The general rule: stateful services (databases, media archives, monitoring data) run on the Synology NAS where they benefit from the integrated backup and snapshot system. Stateless services and compute-heavy workloads run on the Proxmox Docker VM. LXC containers handle lightweight always-on services like Pi-hole and MariaDB. This separation makes it easy to tear down and recreate Docker containers without worrying about data loss.
