I really liked the idea or RancherOS, but somehow it never quite lived up to its promise. In particular, the need to distinguish between root and non-root containers was surprisingly confusing in practice. It effectively broke the promise of “just worry about docker”. Has anyone here adopted it over the long term? What made it stick? Any ideas why SUSE would need/want this?
The enterprise K8S business is compelling, especially all the shops using metal/on-prem. I settled on using Rancher and RKE for production clusters just because it was the simplest way to get HA clusters up within minutes without a PhD in K8S.
But I think a lot of the work they are doing on the other parts of K8S are really interesting: K3S, for example, could become very popular for running on IoT and ARM. K3S really put a smile on my face. You just run it and boom, you have a K8S cluster.
