Minecraft on Raspberry Pi cluster with metrics

Ever wanted to put your Rapsberry Pi cluster to great use? Our team is working remotely, so we started to play Minecraft. I decided I would host the Minecraft server on my Raspberry Pi cluster. This gist will guide you through the steps I took to get a k3s cluster up with k3sup and later installed Minecraft as well as metrics exporter and Prometheus Operator

Raspberry Pi 2/3B/B+/4B Wireless Bridge using Ubuntu Server 18.04 ARM Image and Netplan

The initial goal of this project is to use the raspberry pi in place of my Wireless Range Extender and then going from 3 wireless networks (2.4ghz, 2.4ghz extended, 5ghz) at home to only one (5ghz). This way I'm reducing the exposition to radio waves for the whole familly at home.

Let's go technical

Ok, enough drama for now, let's go technical. 😁
