When installed in a Kubernetes cluster, Rancher will integrate with the cluster's etcd database and take advantage of Kubernetes scheduling for high-availability. -This procedure walks you through setting up a 3-node cluster with RKE and installing the Rancher chart with the Helm package manager. +This procedure walks you through setting up a 3-node cluster with Rancher Kubernetes Engine (RKE) and installing the Rancher chart with the Helm package manager. -> **Important:** It is not supported, nor generally a good idea, to run Rancher on top of hosted Kubernetes solutions such as Amazon's EKS, or Google's GKE. These hosted Kubernetes solutions do not expose etcd to a degree that is manageable for Rancher, and their customizations can interfere with Rancher operations. It is strongly recommended to use hosted infrastructure such as EC2 or GCE instead. +> **Important:** Rancher Management Server can only be run on an RKE managed Kubernetes cluster. Use of Rancher on hosted Kubernetes or other providers is not supported. -> **Important:** For the best performance, we recommend this Kubernetes cluster to be dedicated only to run Rancher.
