Currently, my Kubernetes cluster is running on Ubuntu 20.04 and my upgrade path to the latest LTS 22.04 is dicey. So I figured it's time to look into immutable OSes. There are a few to pick from, Talos, K3OS, Kairos are popular ones. Talos seems to be the most popular, and K3OS is used prett...

Background

I recently decided to try out Ubiquiti after hearing many of my friends and people on social media (Discord especially) speak highly of their experience. On a previous project for replacing my NAS, I did all my own research, bought an Asustor NAS, ended up making a lot of mistakes and...
