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.
homelab
- My homelab setup's re-usable Ansible role for Dynamic DNS from a gateway/router to AWS Route53 (in case anyone is interested)
-
On-Prem Deployments - How are you doing it?
At home in my Homelab I use PXE to provision bare metal nodes, and Ansible to deploy k8s on them. I know this setup isn't really used for anything yet, but I'm kinda proud of it. I can reprovision nodes at will by simply issuing one command, no monitor needed, no keyboard needed. That's the same level of comfort as a hypervisor, but it's bare metal.
-
What's your private cluster environment for Kubernetes-related dev
This is my new repo for my homelab and it includes a k8s.yml file, which is much cleaner and uses more Ansible roles to keep various tasks separated. So you can easily break off k8s.yml and all the k8s roles into your own repo if you want to steal it. I'm not completely done with this setup though, I'm testing FluxCD right now because I might want to ditch ArgoCD.

Bare Metal Solutions
I ended up writing my own, twice actually. Just re-wrote my entire k8s setup for my new homelab. It's published here on gitlab.com. It's not very well documented since it's for personal use but I think it emphasizes how easy it is to setup kubeadm and why there is little reason to make it more complicated than it needs to be.

- Fastest way to set up an k8s environment ?
-
How do you archive your side hobby projects?
I recommend learning docker first, then pick a vps host from vpsbenchmarks, then use k3sup to deploy a kubernetes cluster on that, then follow a getting-started kubernetes tutorial from there. You'll also want to buy a domain name with tld-list and then provision a TLS certificate with cert-manager and letsencrypt (skip steps 1-4 because Google Cloud is overpriced).
-
What do you use as a kubernetes base?
I just installed k3s yesterday using k3sup on 6 VMs (3 masters, 3 workers) each with 2GB RAM ( limited by the actual RAM on hardware, for now ) with Ubuntu 22.04 as the base OS.

What's a cheap way to setup your own Kubernetes cluster locally or remote?
k3s installed with k3sup, longhorn for storage, kube-vip for API VIP, and MetalLB for service load balancer using local subnet, and of course Rancher.

Easiest way to provision and configure ephemeral cluster locally
Yeah, this is the answer, but I would use this with K3S: https://github.com/alexellis/k3sup
