Homelab - How I managed to kill my K3S with SQLite

How it started

One day I have tried to use my plex instance and it was unreachable. I started digging into it.

There were couple of containers that wouldn’t start and also inspection using k9s CLI was taking ages.

Started digging

I have started looking into logs, I saw couple of issues related to SQL - like slow queries.

Then I remembered that K3S is using SQLite as default database, which may not be ideal, for long living clusters.

Homelab - My Kubernetes Journey

Before It Started…

When I began working as a DevOps engineer at Košík.cz, I started using Kubernetes daily for the first time. I quickly realized I had basically no clue how it worked or how to properly manage it. After reading many blogs and exploring Kubernetes for about a year, I noticed much of the setup had been done by my colleagues.

I decided to buy a Raspberry Pi 5 8GB and start my own homelab where I would set up an entire Kubernetes cluster myself. My goal was to gain fundamental knowledge about core components of cloud computing.
