Over the past few months I’ve been building a self-hosted Kubernetes cluster using Raspberry Pis, SSDs, PoE, and various open source tools like Tailscale, Helm, and Longhorn.
I launched a site — SubnetSavy.com — to document everything I’ve learned. It’s written for engineers who want to run real infrastructure at home instead of in the cloud.
Some of the things I cover:
Building a multi-node K8s cluster with Pi 4/5 and SSDs
Automating app deployments with Helm and Terraform
Using Tailscale to create zero-trust access to internal services
Setting up monitoring with Grafana + Prometheus
Storage strategies using Longhorn and local SSDs
Networking with MetalLB, ExternalDNS, Ingress, and Pi-hole

Hands-on gear reviews (SSD, switches, USB-SATA adapters, etc.)
Everything is tested in my own home lab. No affiliate fluff, no generic “Kubernetes 101” content — just real guides for running infra at home.
If you’re into homelab setups, DevOps, or just like building things outside of AWS/GCP, I’d love your feedback: https://subnetsavy.com
