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!

You did WHAT with Ansible?! Automate the Uncommon (my AnsibleFest 2021 Presentation)
Automate the Pi Dramble website I run in my basement with Drupal Pi.

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.

Deploy IRIS Application to Azure Using CircleCI
What we’re going to install into the newly created AKS cluster is located in the helm directory. The descriptive Helmfile approach enables us to define applications and their settings in the helmfile.yaml file.

[2022] [Updated] Alternative to Helmfile
Is there any alternative to https://github.com/roboll/helmfile you are currently using in your company.

Projectsveltos: Manage Kubernetes addons in multiple clusters
Interesting, I have approached this problem using Helmfile (https://github.com/roboll/helmfile) to define a “platform release package.”

How are you handling ILM on kubernetes?
To make managing the Helm deployments a little easier I used helmfile (https://github.com/roboll/helmfile).

Helm Charts Microservices
But in general it's always easier to keep things quite separated. Meaning in separate helm releases. If you want to be able to manage things "together" at will, then you can use helmfile ( https://github.com/roboll/helmfile )

How to Build Software Like an SRE
I agree; helm is too declarative.
Whenever I can, I use helmfile[0] for storing variables for helm since it does add a declarative layer on top of helm.

helmfile sync vs helmfile apply
I went through the Helmfile repo Readme to figure out the difference between helmfile sync and helmfile apply. It seems like unlike the apply command, the sync command doesn't do a diff and helm upgrades the hell out of all releases 😃. But from the word sync, you'd expect the command to apply those releases that have been changed. There is also mention of the potential application of helmfile apply to periodically syncing of releases. Why not use helmfile sync for this purpose? Overall, the difference didn't become crystal clear, and I though there could probably be more to it. So, I'm asking.

Managing multiple repos
helmfile is something i’ve used in the past for this https://github.com/roboll/helmfile

Helm is both "package manager" and "templating engine" - probably the best package manager but horrible template engine
I always felt like dependencies in helm are for very simple non-coupled packages. I many times use Helmfile (https://github.com/roboll/helmfile) to manage dependencies instead of banging my head with vanilla Helm.

So I've installed grafana, loki, and prometheus on the personal Kubernetes cluster via Terraform. Now what?
Once you do that, learn to create dynamic helm charts that use go templating and conditionals: https://github.com/roboll/helmfile
