At work, we are using classical RKE Rancher with Kubernetes with Docker and k3s Rancher with Kubernetes with containerd. So I have experience with both. The problem is, that in our case it often seemed like containerd, at least the way it is used with Kubernetes, is not that stable and reliable. It showed us a lot of bugs and issues, which the legacy Kubernetes never had shown.
So I'm asking myself, how can they suddenly guarantee that all this new stuff is even production ready, when we had not too many but quite substantial issues with it?
(Perhaps the issue was mainly to be found in the whole Rancher thing, but we cannot confirm this.)
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
Just adding my 2 cents from my own experience.
