Rancher is a Kubernetes management solution designed to facilitate the deployment and operation of clusters across various environments and providers. It offers the flexibility to provision Kubernetes clusters from hosted providers, set up compute nodes, and install Kubernetes on them, or seamlessly integrate existing Kubernetes clusters regardless of their location.

Rancher enhances the Kubernetes experience by centralizing authentication and implementing role-based access control (RBAC) for all clusters. This centralized approach empowers global administrators to efficiently manage cluster access from a unified location.
