Mar 31, 2025 · 2 min read · apt gpg keyring legacy

In an effort to balance power efficiency with my tendency to hoard old hardware, I decided to move my overpowered Pi-hole setup from a Mac Mini to a Raspberry Pi 2. (Yes, the Pi 2! A true relic from the past, but still kicking.) Everything was going smoothly — static IP, hostname set, network configured — until I ran …

A few days ago, my wife decided that we - sorry, I — needed to rearrange our kid's room. This involved unplugging various things, including my IKEA VINDSTYRKA air quality sensor.

I feel pretty dumb right now. I used 2 ArgoCD applications for the same thing—one for my Helm chart, the other for flat manifest YAML files. Apparently, thinking isn’t my strong suit. I mean, I could barely remember where I put my coffee, let alone plan a proper ArgoCD setup! So, like any reasonable person, I had to …

Mar 14, 2025 · 3 min read · bitnami sealed-secrets security

I decided to push my Kubernetes manifests to GitHub because running Git locally on the same k3s cluster as ArgoCD seemed like asking for trouble. I mean, what happens if something goes wrong? Suddenly, you’re locked out of your repository, and your applications just sit there looking sad, like ‘Hey, I need a home!’ …
