Homelab

The lab lives in two places: a rack at home and a rack in a datacenter. It is where I try things before they reach production anywhere else, and it runs this site.

Hardware

Five Proxmox VE nodes, each with one job. The full story is in How I set up Proxmox in my homelab.

The front of the rack at home — The rack at home: the PoE switch on top and three of the nodes under it. More photos in the Proxmox post.

Network

Where	Device	Ports
Rack, core	Omada 24-port 2.5GBASE-T L2+	24x 2.5G, 4x SFP+ 10G
Rack, PoE	Omada 8-port 2.5GBASE-T L2+ PoE+	8x 2.5G PoE+, 2x SFP+ 10G
Cabinet	MikroTik CRS305-1G-4S+IN	4x SFP+ 10G, 1x 1G
Every floor	Ubiquiti U7 Lite, 3 in total	Wi-Fi 7, PoE

Platform

Talos Linux managed with Omni: three control planes, four workers, running as VMs on the Proxmox compute nodes.
Cilium as CNI and load balancer, with L2 announcements for the ingress VIP.
Longhorn for persistent storage.
BunkerWeb as the public ingress and web application firewall, with Let’s Encrypt handled centrally.
Traefik for internal .local services.
Argo CD in an app-of-apps layout. Every component is one Application in Git, and nothing is applied by hand after bootstrap.
Prometheus, Alertmanager and Grafana via kube-prometheus-stack.

Tooling around it

GitLab self-hosted for source, CI and the container registry.
Terraform for provisioning and Ansible (with AWX) for configuration.
Coder for cloud development workspaces, which is where this post was written.
