I installed K3s for some hobby projects over the weekend and, so far, I have been very impressed with it.
This got me thinking, that it could be a nice cheap alternative to setting up an EKS cluster on AWS – something I found to be both expensive and painful for the availability that we needed.
Is anybody using K3s in production? Is it OK under load? How have upgrades and compatibility been?
I’ve used truenas scale (comes with k3s preinstalled) and I ended up fucking up the cluster on accident a couple of times (mostly because of power outages), I’ve since moved over to Debian and a manual kubeadm install. Will make upgrading the cluster a bit more painful, but so far it’s stable (ish, I have had issues with the Nvidia containerd backend)
