Nerd Humor
Easter eggs in software are not a new thing. And I will always appreciate a good pop culture reference when I find it. As I was cycling my Kubernetes clusters, I had an issue with some resource contention. Things were not coming up as expected, so I started looking at the Rancher Kubernetes Engine 2…

Centralized Authentication: My Hotel California
When I left my previous role, I figured I would have some time before the idea of a centralized identity server popped back up. As the song goes, “You can checkout any time you like, but you can never leave…” The Short Short Version This is going to sound like the start of a very…

Tech Tip – Formatting External Secrets in Helm
This has tripped me up a lot, so I figure it is worth a quick note. The Problem I use Helm charts to define the state of my cluster in a Git repository, and ArgoCD to deploy those charts. This allows a lot of flexibility in my deployments and configuration. For secrets management, I use…

Using Git Hooks on heterogenous repositories

Running a linter on staged changes before the code is committed and verifying that tests run before the code is pushed makes it easier for developers to write clean code. Doing this with heterogenous repositories, or repos which…

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…
