RKE / Rancher

Rancher 1.6 to 2.0 was the goto bare metal or VM supported kubernetes distribution in the 2017-2019 timeframe around Kubernetes 1.7. The rancher product was integrated into SUSE and continues to support RKE 1 (original) and RKE 2 (FedRAMP compliant). K3s is the edge version of the RKE distribution as a CNCF project.
