ansible-role-k3s VS talos

There is another very good ansible role for k3s, actually better than mine

if you have experience with ansible you can use https://github.com/PyratLabs/ansible-role-k3s

Not OP but there's an excellent galaxy ansible role for k3s and it's idempotent, so if you want to upgrade to a newer version of k3s or tweak settings, or add a node it's supported.

Take it to the next level and let git be the source of truth for k8s using Flux! My home cluster repo is exactly that plus I'm using the ansible-k3s-role Galaxy role. It's based on this k8s at home template.

If you are comfortable with ansible there's a nice Galaxy role that I use.

Experience has been good so far but this is the first I saw of KubeEdge. I’m going to give it an evaluation. I used Ansible https://github.com/PyratLabs/ansible-role-k3s to set up the cluster with some minor adaptions and cleanup scripts.

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.

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.

Looks somewhat similar to the talos Linux project[1]

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

You might be surprised to find that Talos os (linux distro for kubernetes) mostly uses Go: https://github.com/siderolabs/talos

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.

If you’re interested in something not AWS check out Talos https://www.talos.dev/

It’s been around longer than Bottlerocket

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
