high-availability RKE cluster

Three Linux nodes, typically virtual machines, in an infrastructure provider such as Amazon’s EC2, Google Compute Engine, or vSphere.

These nodes must be in the same region/data center. You may place these servers in separate availability zones.

Rancher server data is stored on etcd database that runs on all three nodes.

etcd is a distributed reliable key-value store for the most critical data of a distributed system, with a focus: Simple, Secure, Fast & Reliable.

etcd database requires an odd number of nodes so that it can always elect a leader with a majority of the etcd cluster.

general installation requirements for OS, container runtime, hardware, and networking.

Deployment Size	Clusters	Nodes	vCPUs	RAM
Small	Up to 150	Up to 1500	2	8 GB
Medium	Up to 300	Up to 3000	4	16 GB
Large	Up to 500	Up to 5000	8	32 GB
X-Large	Up to 1000	Up to 10,000	16	64 GB
XX-Large	Up to 2000	Up to 20,000	32	128 GB

Contact Rancher for more than 2000 clusters and/or 20,000 nodes.

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.
