Rancher V2 is an application that manages applications within a Kubernettes environemnt based on AWS EC2 instances. The rancher documents are avaiable on the Rancher web site.

This repo is to setup Rancher V2.* within a Kubernettes high availability environment. The Kubernettes environment is setup on 3 AWS EC2 instances configured in 3 different availability zones. The environment must have 3 nodes for the failover to work correctly.

The Rancher V2.* application will replace the current Rancher V1.* application
