My Very Own Ship of Theseus
A while back, I wrote a little about how the “Ship of Theseus” thought experiment has parallels to software design. What I did not realize is that I would end up running into a physical “Ship of Theseus” of my own. Just another day On a day where I woke up to stories of how…

Moving to Ubuntu 24.04
I have a small home lab running a few Kubernetes clusters, and a good bit of automation to deal with provisioning servers for the K8 clusters. All of my Linux VMs are based on Ubuntu 22.04. I prefer to stick with LTS for stability and compatibility. As April turns into July (missed some time there),…

Building a new home for my proxy server
With my BananaPi up and running again, it’s time to put it back in the server cabinet. But it’s a little bit of a mess down there, and I decided my new 3D modeling skills could help me build a new home for the proxy. Find the Model When creating a case for things, having…

Automating Grafana Backups
After a few data loss events, I took the time to automate my Grafana backups. A bit of instability It has been almost a year since I moved to a MySQL backend for Grafana. In that year, I’ve gotten a corrupted MySQL database twice now, forcing me to restore from a backup. I’m not sure…

My Introduction to Kubernetes NetworkPolicy
The Bitnami Redis Helm chart has thrown me a curve ball over the last week or so, and made me look at Kubernetes NetworkPolicy resources. Redis Chart Woes Bitnami seems to be updating their charts to include default NetworkPolicy resources. While I don’t mind this, a jaunt through their open issues suggests that it has…

Environment Woes
No, this is not a post on global warming. As it turns out, I have been provisioning my Azure DevOps build agents somewhat incorrectly, at least for certain toolsets. Sonar kicks it off It started with this error in my build pipeline: I provision my build agents using the Azure DevOps/GitHub Actions runner images repository,…

A Tale of Two Proxies
I am working on building a set of small reference applications to demonstrate some of the patterns and practices to help modernize cloud applications. In configuring all of this in my home lab, I spent at least 3 hours fighting a problem that turned out to be a configuration issue. Backend-for-Frontend Pattern I will get…
