Rancher Requirements

RKE

high-availability RKE cluster

• Three Linux nodes, typically virtual machines, in an infrastructure provider such as Amazon’s EC2, Google Compute Engine, or vSphere.
• A load balancer to direct front-end traffic to the three nodes.
• A DNS record to map a URL to the load balancer. This will become the Rancher server URL, and downstream Kubernetes clusters will need to reach it.
