Welcome to a private-cloud demonstration of hosting a bare-metal Kubernetes cluster using the cheap and humble Raspberry Pi computer.
This private cloud hosts all the usual stuff like Prometheus, Grafana, Home Assistant, Ubiquiti UniFi Controller, PiHole, etc. More interesting though are the solar-powered ESP WiFi devices transmitting tons of metrics and alerts from the surrounding countryside.
All source code and firmware is free and available on GitHub , however if you would like a demo of the following services, use contact page to request a login.
