Rancher is a Kubernetes management tool designed for deploying and managing clusters across various environments and providers. It offers the flexibility to provision Kubernetes clusters from hosted providers, manage the provisioning of compute nodes, and subsequently install Kubernetes on these nodes. Additionally, Rancher provides the capability to import and manage existing Kubernetes clusters, regardless of their location.

One of Rancher’s notable features is its ability to enhance Kubernetes functionality. It achieves this by centralizing authentication and implementing role-based access control (RBAC) for all clusters. This centralized approach empowers global administrators, enabling them to efficiently manage cluster access from a single, unified location.
