Install Kubernetes on Red Hat Linux (RHEL 7)
kubeadm is the way to go for installing kubernetes on RHEL. Though in alpha, it works for most of the use cases.
You can find the installation instructions on the kubeadm installation page and steps to use it on the using kubeadm page.
Best and easy is in the eye of the beholder, but maybe you want to review the install options I tried to describe and categorize in the post Kubernetes: A Little Guide to Install Options against your requirements?
