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.

There are only 12 binaries in Talos Linux
Super cool. I always enjoy reading about systems that challenge, well, "ossified" assumptions. An OS not providing a shell, for example? Madness! ... or is it genius, if the OS has a specific purpose...? It's thought-provoking, if nothing else.
I'm a bit skeptical of parts. For instance, the "init" binary being less than 400 lines of golang - wow! And sure, main.go [1] is less than 400 lines and very readable. Then you squint at the list of imported packages, or look to the left at the directory list and realize main.go isn't nearly the entire init binary.
That `talosctl list` invocation [2] didn't escape my notice either. Sure, the base OS may have only a handful of binaries - how many of those traditional utilities have been stuffed into the API server? Not that I disagree with the approach! I think every company eventually replaces direct shell access with a daemon like this. It's just that "binary footprint" can get a bit funny if you have a really sophisticated API server sitting somewhere.

Show HN: Workout Tracker – self-hosted, single binary web application
Where `kube.cue` sets reasonable defaults (e.g. image is /). The "cluster" runs on a mini PC in my basement, and I have a small Digital Ocean VM with a static IP acting as an ingress (networking via Tailscale). Backups to cloud storage with restic, alerting/monitoring with Prometheus/Grafana, Caddy/Tailscale for local ingress.

Gokrazy – Go Appliances
Talos Linux basically implements their entire userspace in Go and its similar to BottleRocketOS, because it is designed to host Kubernetes.

K3s – Lightweight Kubernetes
I've been using a 3 nuc (actually Ryzen devices) k3s on SuSE MicroOS https://microos.opensuse.org/ for my homelab for a while, and I really like it. They made some really nice decisions on which parts of k8s to trim down and which Networking / LB / Ingress to use.
The option to use sqlite in place of etcd on an even lighter single node setup makes it super interesting for even lighter weight homelab container environment setups.
I even use it with Longhorn https://longhorn.io/ for shared block storage on the mini cluster.
If anyone uses it with MicroOS, just make sure you switch to kured https://kured.dev/ for the transactional-updates reboot method.
I'd love to compare it against Talos https://www.talos.dev/ but their lack of support for a persistent storage partition (only separate storage device) really hurts most small home / office usage I'd want to try.

Bottlerocket – Minimal, immutable Linux OS with verified boot
If you’re interested in something not AWS check out Talos https://www.talos.dev/
It’s been around longer than Bottlerocket

What kubernetes platforms do you use in your production environment?
Can't talk about work, but my homelab is Azure and Oracle managed k8s (AKS/OKE), with onprem Talos soon (Turing Pi 2). My Flux monorepo has the details. OKE performs noticably worse (update cycle, features, control plane performance), but it provides 4 ARM cores and 24GB RAM free so I can't complain

Upgrading Hundreds of Kubernetes Clusters
When it came to deployment, I had several options, and I chose the hard way: deploying Kubernetes on bare metal nodes using KubeSpray. Troubleshooting bare metal Kubernetes deployments honed my skills in pinpointing issues. This hands-on experience provided a deep understanding of how each component, like the Control Plane, kubelet, Container Runtime, and scheduler, interacts to orchestrate containers.

How many of you are running kubernetes on prem?
About 1yr ago I ran k8s with 300 nodes using kube spray https://github.com/kubernetes-sigs/kubespray . Never had any real issue with it. We did finally move to the cloud though.

Building your own Kubernetes distribution
We build our own distro called Compliant Kubernetes, and we use (a fork of) kubespray to install the base Kubernetes layer. Our distro is entirely open source, so you can use it as a reference, if you want.
