Introduction

SUSE® Rancher Prime RKE2, also known as RKE Government, is Rancher’s next-generation Kubernetes distribution.

It is a fully conformant Kubernetes distribution that focuses on security and compliance within the U.S. Federal Government sector.

To meet these goals, SUSE® Rancher Prime RKE2 does the following:

How is this different from RKE or SUSE® Rancher Prime K3S?

SUSE® Rancher Prime RKE2 combines the best-of-both-worlds from the 1.x version of RKE (hereafter referred to as RKE1) and SUSE® Rancher Prime K3S.

From SUSE® Rancher Prime K3S, it inherits the usability, ease-of-operations, and deployment model.

From RKE1, it inherits close alignment with upstream Kubernetes. In places SUSE® Rancher Prime K3S has diverged from upstream Kubernetes in order to optimize for edge deployments, but RKE1 and RKE2 can stay closely aligned with upstream.

Importantly, SUSE® Rancher Prime RKE2 does not rely on Docker as RKE1 does. RKE1 leveraged Docker for deploying and managing the control plane components as well as the container runtime for Kubernetes. RKE2 launches control plane components as static pods, managed by the kubelet. The embedded container runtime is containerd.

Why two names?

It is known as SUSE® Rancher Prime RKE2 as it is the next iteration of the Rancher Kubernetes Engine for datacenter use cases. The distribution runs standalone or integrated into Rancher. Automated provisioning of new SUSE® Rancher Prime RKE2 clusters is available in Rancher v2.6+.

It is also known as RKE Government in order to convey another use case and sector it currently targets.
