Rebuilding my homelab

A month or so ago I started with building a homelab for running Kubernetes. I choose Raspberry Pi’s to run my workloads on. I started with the use of kubeadm to deploy Kubernetes and chose the blog of Alex Ellis as my starting point. I ran into some problems in my attempts to get it working but finally I succeeded to get it working. Soon after that Rancher Labs, released K3S which was targeted at edge and iot solutions and perfect for running on Raspberry Pi’s.
