Clusternet: Multi-Cluster Kubernetes

by Shriira Press

A practical, in-depth guide to Clusternet, the open-source multi-cluster management platform for Kubernetes. Learn how Clusternet manages many clusters as one: the multi-cluster problem (cluster sprawl, fragmented management), the hub-and-spoke architecture (parent and child clusters, hub/scheduler/agent), cluster registration (the agent and the pull model), the API and resources (ManagedCluster, Subscription, Localization/Globalization), cross-cluster scheduling (label-based, dynamic placement), deploying applications (propagation, Helm, lifecycle), cross-cluster access and multi-tenancy (the parent as a secure gateway, RBAC), operations and best practices, and Clusternet in practice.
