All is in the title: Is RKE (from Rancher) production ready?
I tried to google it without success.
And is there any best practices to set up a production cluster with it?
Thanks for your help.
This question is rather hard to answer without knowing your acceptance criteria. What is production readiness from your point of view?
Are you concerned about the conformance of the k8s deployment through rke? Check https://www.cncf.io/certification/software-conformance/ - Rancher is listed there. Maybe give https://github.com/heptio/sonobuoy a try.
Cheers
