Rancher
What it is
Rancher is a Kubernetes management platform for operating multiple clusters and containerized workloads. It provides cluster provisioning and version management, as well as visibility, diagnostics, monitoring, alerting, and centralized audit. Supported Kubernetes distributions include EKS, AKS, GKE, RKE, and K3s. Teams can apply consistent access and security policies across managed clusters and connect external authentication providers such as Active Directory, GitHub, Azure AD, Okta, Google OAuth, and generic OIDC. Rancher can run kube-bench compliance scans that report test results and remediation steps for failed checks. Its documented integrations include Harvester, Longhorn, NeuVector, Kubewarden, Elemental, Fleet, SUSE Observability, and Rancher Desktop. The free edition is open source and includes community support; Rancher Prime editions include enterprise support. Prime editions also include professional services and a trusted private container registry. Quick-start installation calls for a Linux host with at least 4 GB of memory and a supported Docker version. Rancher began in 2014 and became part of SUSE in 2020.
