Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Why is it so hard to find a 5 port PoE switch where all 5 ports are PoE?
https://www.pidramble.com - but you do need to power the router. 5th port is an uplink

Heatsinks for Raspberry Pi cluster with PoE
Don't bother. Just put them on an open stack and blow a quiet Noctua fan sideways through the stack. I used to have a four-pi4 cluster ala https://www.pidramble.com and one fan blowing back to front was easily good enough. I also removed the fans from the official PoE HATs since they sounded like rocket engines no matter what I did.

How would I power multiple RPI's?
There's no rack, it's simply on the corner of my desk. I haven't made photos of it but it looks pretty much like Jeff Geerling's Dramble: https://www.pidramble.com/

Considering building a NUC k8s cluster, looking for inspiration
Had a pi 'dramble' just like this one and it worked fine. I ran k3s at the time on it. Since it was a lab experimentation thing, I didn't throw more hardware at it, but I could have likely gotten similar results with a bunch of Vagrant/VirtualBox VMs on one NUC.
- Pi k8s! This is my pi4-8gb powered hosted platform. 8 pi4s for kubeadm k8s cluster, and one for a not so 'nas' share. I use gitlab runners with helmfile to manage my applications. Running over a year and finally passed the CKA with most of my practice on this plus work clusters. AMA welcome!

A quick write-up of my current setup with a Raspberry Pi 4
How is latency and stuff? Any slowness that you wouldn't expect from the software that may come from running it on a rpi4? I've been thinking of setting up a few services, but I kinda want to do something like the Pi Dramble, wasn't even aware that a single pi would have the power to run all of these services. Though I'm not actually surprised it does.

Creating a modular pi cluster?
A couple years ago when I thought I'd have to get into kubernetes for a living, I built a 4x4GB pi4 cluster with the exact parts list from Jeff Geerling's "dramble" setup (link) and did a bunch of experimentation with k3s as a lightweight cluster solution. Worked pretty amazingly for things like "spin me up 10 more of those things" and for moving things around to upgrade the SD card on the 3rd pi while keeping the services running on the other pi. But I don't need to do kubernetes for a living so the cluster is just sitting here collecting dust powered-down basically.

Kubernetes 20 Pi cluster
I see this kind of question asked a lot when people are posting their Kubernetes Pi clusters. The rpi 4 quad core with 4-8GB RAM gives a lot of potential for the price in a kuberenetes setup I feel. I found the pi dramble project interesting, and even more the turing pi using rpi compute modules. Are NUCs really a cheaper alternative for a kubernetes cluster, every time I start try to come up with something I end up with a far more expensive setup and fewer cores. Any hints on viable setups, e.g. replacing 4x POE powered RPI 4's.?

My PoE Pi Cluster.
My setup is exactly the same as the top photo on https://www.pidramble.com just with the stack'o'pi zip-tied to the switch so I can move it around without the things sliding around.

Kubernetes CI/CD Pipelines
Applying Kubernetes manifests individually is problematic because files can get overlooked. Packaging your applications as Helm charts lets you version your manifests and easily repeat deployments into different environments. Helm tracks the state of each deployment as a "release" in your cluster.

How to take down production with a single Helm command
Explanation here: https://github.com/helm/helm/issues/12681#issuecomment-19593...
Looks like it's a bug in Helm, but actually isn't Helm's fault, the issue was introduced by Fedora Linux.

The 2024 Web Hosting Report
It’s also well understood that having a k8s cluster is not enough to make developers able to host their services - you need a devops team to work with them, using tools like delivery pipelines, Helm, kustomize, infra as code, service mesh, ingress, secrets management, key management - the list goes on! Developer Portals like Backstage, Port and Cortex have started to emerge to help manage some of this complexity.

Deploying a Web Service on a Cloud VPS Using Kubernetes MicroK8s: A Comprehensive Guide
Kubernetes orchestrates deployments and manages resources through yaml configuration files. While Kubernetes supports a wide array of resources and configurations, our aim in this tutorial is to maintain simplicity. For the sake of clarity and ease of understanding, we will use yaml configurations with hardcoded values. This method simplifies the learning process but isn’t ideal for production environments due to the need for manual updates with each new deployment. Although there are methods to streamline and automate this process, such as using Helm charts or bash scripts, we’ll not delve into those techniques to keep the tutorial manageable and avoid fatigue — you might be quite tired by that point!

Deploy Kubernetes in Minutes: Effortless Infrastructure Creation and Application Deployment with Cluster.dev and Helm Charts
Helm is a package manager that automates Kubernetes applications' creation, packaging, configuration, and deployment by combining your configuration files into a single reusable package. This eliminates the requirement to create the mentioned Kubernetes resources by ourselves since they have been implemented within the Helm chart. All we need to do is configure it as needed to match our requirements. From the public Helm chart repository, we can get the charts for common software packages like Consul, Jenkins SonarQube, etc. We can also create our own Helm charts for our custom applications so that we don’t need to repeat ourselves and simplify deployments.

Introduction to Helm: Comparison to its less-scary cousin APT
Generally I felt as if I was diving in the deepest of waters without the correct equipement and that was horrifying. Unfortunately to me, I had to dive even deeper before getting equiped with tools like ArgoCD, and k8slens. I had to start working with... HELM.
