As a self-hosted enthusiast and a person who cares about green tech, I have recently started a journey to self host more and more of the services I use frequently.
At the last Open Source Summit Japan, I discovered PostmarketOS, a real Linux distribution for phones, which made me start experimenting with the possibilities reused hardware could bring to a more sustainable future.
In this talk, I strive to describe the process and approach I had to setup a reliable, resilient Kubernetes cluster using only old phones with PostmarketOS and k3s, as well as giving tips to find more sustainable uses for said technologies.
The idea is to have a talk discussing how I set up the cluster and some tips and tricks to manage said clusters without them getting out of control. I have experience with kubernetes and would love to share different possibilities for PostmarketOS that could be applied for sustainability purposes.
