A local Kubernetes cluster is installed in the single Docker container, and Rancher is installed on the local cluster. Docker Install įor test and demonstration purposes, Rancher can be installed with Docker on a single node. In the future, you can add nodes to the cluster to get a high-availability Rancher server. However, this option is useful if you want to save resources by using a single node in the short term, while preserving a high-availability migration path. In this case, the Rancher server doesn't have high availability, which is important for running Rancher in production. Rancher can be installed on a single-node Kubernetes cluster. The EKS cluster deployed is production-ready and follows AWS best practices. Rancher can be installed on to Amazon Elastic Kubernetes Service (EKS) through the AWS Marketplace. Rancher on EKS Install with the AWS Marketplace 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. Note the restrictedAdmin Helm chart option available for the Rancher Server. 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.The Rancher management server can be installed on any Kubernetes cluster, including hosted clusters, such as Amazon EKS clusters. 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.
