Is RKE (from Rancher) production ready?

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?

• High availability? Can be achived
• (Enterprise) Customer Support? Can be requested

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
