My Homelab

A few years ago I started building my homelab with a Raspberry Pi 4 and an HP G3 Mini I picked up on Vinted. Since then I kept adding pieces whenever I found a good deal on second-hand sites, and today, after more than 2 years, I think I've officially reached the end ( maybe ). This is my current setup. Everything is second-hand except the switch and the router . RACK - Fully 3D printed in PETG on a Bambu Lab X2D ( Design by Ilan Kushnir ) NODE PC: 3-node Proxmox VE - pve-01 : Ryzen 7 5700U (8C/16T), 62 GB RAM, 512 GB NVMe (ZFS) + 2 TB HDD (ZFS) + 256 GB SATA SSD - pve-02 : Core i7-6700T (4C/8T), 32 GB RAM, 256 GB NVMe (ZFS) + 2 TB HDD (ZFS) - pve-03 : Core i5-7500T (4C/4T), 32 GB RAM, 256 GB NVMe (ZFS) + 2 TB HDD (ZFS) NETWORK - UniFi Dream Router 7 : gateway, firewall, inter-VLAN routing - UniFi USW-Flex-2.5G-8-PoE, with an SFP+ DAC uplink to the UDR7 - VLANs: management, homelab infra, and a dedicated one for Kubernetes. Proxmox uses a single VLAN-aware bridge, so each VM just gets tagged. STORAGE - QNAP TS-431 with 16Tb OTHER - Raspberry Pi 4 driving 2 displays: - 7.84" front display showing Grafana dashboards - 0.91" OLED status display running a small Python script that shows IP, temperatures and CPU usage SOFTWARE I'm currently rebuilding everything from scratch, starting with pve-01, which now runs the Kubernetes cluster: - Kubernetes: Talos Linux (1 control plane + 4 workers as VMs), provisioned end-to-end with Terraform: VMs, Talos config, bootstrap and base components - Networking: Cilium with kube-proxy replacement and L2 LoadBalancer - Storage: OpenEBS LocalPV, with VM boot disks on NVMe and data volumes on HDD - GitOps: ArgoCD app-of-apps. Everything in the cluster lives in git - Secrets: OpenBao in an LXC (outside the cluster, so it survives rebuilds) + External Secrets Operator - Ingress: Nginx Proxy Manager (Let's Encrypt wildcard) -> Traefik - Monitoring & logs: kube-prometheus-stack (Prometheus, Grafana, Alertmanager), including the Talos control plane and etcd, plus Loki + Alloy for pod and node logs - Other stuff: Glance dashboard, Headlamp, VS Code server. pve-02 and pve-03 will be dedicated to other projects. Happy to answer questions, and any tips or suggestions for improvements are welcome!
