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?
Define production lol. I've used it for a CI cluster for a few years. Have had to recreate it a few times due to database corruption (despite using etcd across 3 nodes).
Honestly Rancher management is more of a pain than manually managing via ansible or something. And swapping to CRI-O backend instead of containerd js a huge pain for Rancher/RKE2, but pretty easy with k3s.
