Our verdict on Open Cluster Management
Open Cluster Management (OCM) is an open-source, community-driven project for managing multiple Kubernetes clusters across multicluster and multicloud environments. Its hub-and-spoke architecture registers clusters, maintains inventory, distributes Kubernetes resources, places workloads and policies, and extends management capabilities through optional add-ons. It is suited to platform teams that want centralized governance while retaining control of the management plane.
OCM’s strongest area is declarative fleet coordination. The ManifestWork API distributes Kubernetes resources, while dynamic placement assigns workloads and content across clusters. Policy distribution, governance, auditing, and remediation support a consistent operating model across the fleet. Application lifecycle management is available through add-ons, and FleetConfig Controller provides declarative hub and spoke lifecycle management. Cluster API integration adds support for cluster lifecycle workflows, making OCM a fit for teams that want management functions exposed through Kubernetes-oriented APIs.
The project also fits into a broad cloud-native ecosystem, with integrations including Argo CD, Argo CD Agent, Argo Workflows, Helm, Istio, KubeVela, Kueue, OpenTelemetry, and Submariner. The tradeoff is operational ownership: OCM is self-hosted rather than a vendor-hosted SaaS product, so teams manage the control plane themselves. Its supported environments include Vanilla Kubernetes, Amazon EKS, and Google GKE; Azure AKS support is on the roadmap. Choose OCM for governed hub-and-spoke fleet management and extensible, API-driven workflows. Consider an alternative if you need a hosted service or broader verified environment coverage.
