Zero Downtime Seltzer

March 8, 2023

I was recently gifted a dual pressure gas regulator, so it’s time to upgrade my kegerator. For this project, I have a pair of upgrades in mind: add a second gas line to make use of the new regulator and install some sensors to monitor how much liquid is left in each keg.

In this article, we’ll cover adding a second gas line as well as cutting a utility hole for powering the sensors. A following article will cover installing the sensors and monitoring keg state.

Creating a Prometheus Exporter for Pihole

February 14, 2021

Pihole is a self-hosted DNS forwarder and filter for blocking ad domains. I run pihole on my network and have found it to be great fodder for testing devops / SRE concepts. Previously, I took a stab at running pihole on kubernetes. Since then, I’ve started running prometheus and grafana to collect and display metrics. What better way to play with those platforms than with metrics from pihole!

I’m a big fan of running absolutely everything in docker, so I previously had a pi-hole container on my network, but it’s time to up my game.

Kubernetes on Raspberry Pi

If you have a few raspberry pis lying around and you’re looking for an interesting way to get started with kubernetes, this is the tutorial for you! Below, I’ve outlined a fairly straight forward method for getting a stripped down install of kubernetes (k3s) installed across a pair of raspberry pis.
