Synced, But Not: ArgoCD Differencing Configuration
Some of the charts in my Loki/Grafana/Tempo/Mimir stack have an odd habit of not updating correctly in ArgoCD. I finally got tired of it and fixed it… I’m just not 100% sure how. Ignoring Differences At some point in the past, I had customized a few of my Application objects with ignoreDifferences settings. It was…

Proxy Down!
A simple package updates seems to have adversely affected the network on my Banana Pi proxy server. I wish this was a post on how I solved it, but, alas, I haven’t solved it. It was a simple upgrade… That statement has been uttered prior to massive outages a time or two. I logged in…

More GitOps Fun!
I have been curating some scripts that help me manage version updates in my GitOps repositories… It’s about time they get shared with the world. What’s Going On? I manage the applications in my Kubernetes clusters using Argo CD and a number of Git repositories. Most of the ops- repositories act as “desired state” repositories.…

Do the Right Thing
My home lab clusters have been running fairly stable, but there are still some hiccups every now and again. As usual, a little investigation lead to a pretty substantial change. Cluster on Fire My production and non-production clusters, which mostly host my own projects, have always been pretty stable. Both clusters are set up with…

Git Out! Migrating to GitHub
Git is Git. Wherever it’s hosted, the basics are the same. But the features and community around tools has driven me to make a change. Starting Out My first interactions with Git happened around 2010, when we decided to move away from Visual SourceSafe and Subversion and onto Git. At the time, some of the…

A little maintenance task
As I mentioned in my previous post, I ran into what I believe are some GPU issues with my Dell 7510. So, like any self-respecting nerd (is that an oxymoron?), I ordered a replacement part from parts-people.com and got to work. Prep Work As with most things these days, you can almost always find some…

Tech Tip – Interacting with ETCD in Rancher Kubernetes Engine 2
Since cycling my cluster nodes is a “fire script and wait” operation, I kicked one off today. I ended up running into an issue that required me to dig a bit into ETCD in RKE2, and could not find direct help, so this is as much my own reference as it is a guide for…

What’s in a home lab?
A colleague asked today about my home lab configuration, and I came to the realization that I have never published a good inventory of the different software and hardware that I run as part of my home lab / home automation setup. While I have documented bits and pieces, I never pushed a full update.…

Tech Tip – You should probably lock that up…
I have been running in to some odd issues with ArgoCD not updating some of my charts, despite the Git repository having an updated chart version. As it turns out, my configuration and lack of Chart.lock files seems to have been contributing to this inconsistency. My GitOps Setup I have a few repositories that I…
