Re-configuring Grafana Secrets
I recently fixed some synchronization issues that had been silently plaguing some of the monitoring applications I had installed, including my Loki/Grafana/Tempo/Mimir stack. Now that the applications are being updated, I ran into an issue with the latest Helm chart’s handling of secrets. Sync Error? After I made the change to fix synchronization of the…

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…

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?

Did I do it? Yes. Is there room for improvement? Of course, its a software project. The Problem With RKE1, I…

Nothing says “Friday Night Fun” like crashing an RKE Cluster!
Yes… I crashed my RKE clusters in a big way yesterday evening, and I spent a lot of time getting them back. I learned a few things in the process, and may have gotten the kickstart I need to investigate new Kubernetes flavors. It all started with an upgrade… All I wanted to do was…

What’s in a (Release) Name?
With Rancher gone, one of my clusters was dedicated to running Argo and my standard cluster tools. Another cluster has now become home for a majority of the monitoring tools, including the Grafana/Loki/Mimir/Tempo stack. That second cluster was running a little hot in terms of memory and CPU. I had 6 machines running what 4-5…
