Core APIs for open cluster management

Open Cluster Management API

The api repository defines relevant concepts and types for problem domains related to managing 0..* Kubernetes clusters.

Purpose

This library is the canonical location of the Open Cluster Management API definition.

• API for cluster registration independent of cluster CRUD lifecycle.
• API for work distribution across multiple clusters.
• API for dynamic placement of content and behavior across multiple clusters.
• API for building addon/extension based on the foundation components for the purpose of working with multiple clusters.

Consumers

Various projects under Open Cluster Management leverage this api library.

• registration: implements ManagedCluster, ManagedClusterSet,ClusterClaim for cluster registration and lifecycling.
• work: implements Manifestwork for native kubernetes resource distribution to multiple clusters.
• addon-framework: implements ClusterManagementAddOn, ManagedClusterAddOn for addon management.
• placement: implements Placement for cluster selection with various policies to deploy workloads.
• registration-operator: implements ClusterManager, Klusterlet as an operator to deploy registration, work and placement.

Use case

With the Open Cluster Management API and components, you can use the clusteradm CLI to bootstrap a control plane for multicluster management. The following diagram illustrates the deployment architecture for the Open Cluster Management.
