helm-charts VS pihole-kubernetes

The go to solution for a k8s monitoring setup is https://github.com/prometheus-community/helm-charts/tree/mai...

That's why Kube-Prometheus-Stack was created. It installs a collection of Kubernetes manifests, Grafana dashboards, and Prometheus rules, providing an easy-to-operate, end-to-end Kubernetes cluster monitoring solution with Prometheus using the Prometheus Operator.

Step 1: Installing Kube-prometheus-stack

Installation example for prometheus:

Prometheus can be deployed using the Prometheus Helm Chart. This helm chart contains a lot of features such as the already mentioned Push Gateway, Alert Manager and so on. For simplicity reasons of this tutorial I will not show all the Helm chart configuration but you can see a real example used by me here.

Building upon Bartłomiej Płotka's insightful blog on Prometheus and its passthrough agent mode, this post dives into implementing multi-cluster Prometheus support. Notably, the official inclusion of support in the widely-used kube-prometheus-stack came with the release in July 2023, making it easier to extend Prometheus monitoring across clusters.

The first thing you'll need, of course, is at least one backend to store metrics. So install Prometheus now:

I'm running 2 instances of pihole on my k8s(k0s) cluster. I was feeling like a slacker so I started using this helm chart here to deploy them instead of writing my own https://github.com/MoJo2600/pihole-kubernetes. The problem is, they use a Deployment and not a Stateful Set. This means if I can't raise the deployment count unless I stop using persistent storage.

The only thing I've really got is PiHole for k8s (https://github.com/MoJo2600/pihole-kubernetes/tree/master/charts/pihole).
