Rancher

Rancher is a complete software stack for teams adopting containers. It addresses the operational and security challenges of managing multiple Kubernetes clusters.

When to Use

• Multi-Cluster: Manage EKS, AKS, GKE, and on-prem RKE2 clusters from a single pane of glass.
• User Management: Unified Auth (SSO) across all clusters.
• Edge: Manage thousands of small K3s clusters (retail/IoT).

Core Concepts

RKE2

Rancher's Government-grade Kubernetes distribution. Secure by default, FIPS compliant.

Fleet
