SRE for a betting company for money and having fun with my raspberry's homelab cluster for fun

A Raspberry Cluster Upgrade

Monitoring I had k8s running for a while and when a had issues with something It was not easy to troubleshoot. So I started looking into adding logging and monitoring to the cluster. It happens that prometheus + grafana + fluentd was way too heavy for 2 raspberry with my application running in it. I mean, just my application was using like 60-70% of the RAM resources… No way I could add prometheus to it…

Control the Raspberry Fan

Raspberries can be really loud (20th September 2019) When you have a raspberry near you with the little fan connected to the 5v you will notice that it can be really annoying. I was already loosing my mind with it so I had to fix it. I was searching the web, and found that controlling the fan speed based on the temp. was not that hard. Besides I have never had any experience with electronics so this sound really fun 😄

My Raspberry PI Cluster

My k8s adventure Intro The story starts in the middle of 2018 when I’m hearing about sports betting (football) often at that time. It was my first contact with the betting world and I was curious so I sign-up in some russian betting websites that someone advised. Later I found my self having some difficulties so I started following some facebook groups and started thinking that I could improve my chances, or at least make my life easier, if I automate some stuff.
