The past year or so, I’ve been contributing to the OKD Working Group. OKD is the community-supported upstream of Red Hat OpenShift. Kubernetes is now being used for everything from High Performance Computing to classroom learning, and OKD/OpenShift is the most polished implementation. Ultimately, I think that polish makes it more accessible to System Administrators/DevOps and users alike.
OKD allows users to install clusters on a variety of platforms including Amazon Web Services, Google Compute Platform, vSphere, and more. There is even a bare metal installation.
