![]() Rancher and Amazon Web Services collaborated on a quick start guide for deploying Rancher on an EKS Kubernetes cluster following AWS best practices. Automated Quickstart to Deploy Rancher on Amazon EKS When you upgrade the RancherD binary, both the Kubernetes cluster and the Rancher Helm chart are upgraded. In both the RancherD install and the Helm CLI install, Rancher is installed as a Helm chart on a Kubernetes cluster.Ĭonfiguration and upgrading are also simplified with RancherD. RancherD is a single binary that first launches an RKE2 Kubernetes cluster, then installs the Rancher server Helm chart on the cluster. Note: RancherD was an experimental feature available as part of Rancher v2.5.4 through v2.5.10 but is now deprecated and not available for recent releases. High-availability Kubernetes Install with RancherD For K3s clusters, only two nodes are required. ![]() For RKE clusters, three nodes are required to achieve a high-availability cluster. We recommend using Helm, a Kubernetes package manager, to install Rancher on multiple nodes on a dedicated Kubernetes cluster. Rancher can be installed on these main architectures: High-availability Kubernetes Install with the Helm CLI For more information, see the section about the restricted-admin role. When this option is set to true, the initial Rancher user has restricted access to the local Kubernetes cluster to prevent privilege escalation. The restrictedAdmin Helm chart option was added. In Rancher v2.5, the Rancher management server can be installed on any Kubernetes cluster, including hosted clusters, such as Amazon EKS clusters.įor Docker installations, a local Kubernetes cluster is installed in the single Docker container, and Rancher is installed on the local cluster. It was available as part of Rancher v2.5.4 through v2.5.10 but is now deprecated and not available for recent releases. ![]() RancherD was an experimental tool for installing Rancher a single binary that first launched an RKE2 Kubernetes cluster, then installed the Rancher server Helm chart on the cluster.RKE2 is a fully conformant Kubernetes distribution that focuses on security and compliance within the U.S.It is newer than RKE, easier to use, and more lightweight, with a binary size of less than 100 MB. K3s (Lightweight Kubernetes) is also a fully compliant Kubernetes distribution.RKE (Rancher Kubernetes Engine) is a certified Kubernetes distribution and CLI/library which creates and manages a Kubernetes cluster.You can interact with downstream Kubernetes clusters through the Rancher server’s user interface. The Rancher server manages and provisions Kubernetes clusters.This section provides an overview of the architecture options of installing Rancher, describing advantages of each option.
