SCM-Manager: Old love never dies!

Almost ten years after being an active team member on the open source project at #Cloudogu, I recently had the honor of contributing again.

Almost ten years later, maintaining a fully open sovereign alternative to the widespread closed or open core platforms seems more important then ever.

Cascading deletion of Argo CD apps using GitOps

I learned to consider always setting the finalizer (resources-finalizer.argocd.argoproj.io) with all Argo CD apps a good practice.
Edit: Exception: root app of apps.

💡 This way, users won't be surprised to find that the resources they wanted to delete keep on running but are no longer tracked in Git or by Argo CD (AKA orphaned).

#Kubernetes Gateway API: a sobering look

My biggest pain with ingresses are regex redirects.
So many of us relied on the notorious #nginx annotations or even deployed separate nginx instances for more complex redirects.

With #GatewayAPI we have HttpRoutes with RequestRedirect filters but they don't have a path type regex.

How to migrate nginx annotations?
The go-to solutions seem proprietary CRDs like #traefik middleware.

So, no Gateway API, then?

Please tell me that I'm missing something!

Is kubectl krew (plugin manager) a supply chain risk?

It makes it really easy to install and execute binaries on your machine that have access to your k8s clusters.

* Be careful what you install
* Keep up to date: k krew upgrade or using topgrade
* clean up regularly! A lot of plugins on the index are deprecated.

Some helpful and famous plugins have not been updated for years. Remember rbac-view? Last commit was 8 years ago.

Today is the best day for
k krew upgrade
k krew list
k krew rm

> For years, you’ve sat in front of a rectangle, moving tinier rectangles, only to learn that AI can now move those rectangles 10x better. As someone outside the equity class, you begin to wonder what your role is in this new paradigm. And whether rectangles were ever your ticket to happiness in the first place.

Heads-up: new #Grafana #Helm charts repo coming in Jan '26.

To improve governance, the repo will move from Grafana to a community home.

From: grafana/helm-charts
To: grafana-community/helm-charts

For us users, this means that likely by the end of Jan, we need to update our Helm repo URLs, but the charts stay compatible.

This is a great effort to shorten the PR queue in accordance with Grafana the company.
I like the analogy to prometheus-community/helm-charts. This could become a pattern 👍️
