Personal homelab K3s cluster project

This project automatically builds a K3s cluster on a Turing Pi 2 using Ansible.

Currently a work in progress, so don't expect this to run out of the box. Since this is a personal project, it's heavily configured towards my own hardware and I don't have any plans to change this for the foreseeable future. I'm using this project to learn about self-hosting, IaaC, DevOps, etc. -- be careful about taking inspiration from anything you see here.
