KubeStellar: Multi-Cluster Configuration Management for Edge and Multi-Cloud

by Shriira Press

KubeStellar is a CNCF sandbox project that tackles a problem every growing platform team hits: once you have more than one Kubernetes cluster, deploying and configuring workloads across them stops being simple. KubeStellar keeps it simple by letting you author workloads in their native form in a control plane that behaves like an ordinary API server, then placing them onto chosen clusters with a small declarative rule called a BindingPolicy. This book builds the system from the ground up: the Workload Description Spaces where you author objects, the Inventory and Transport Space that knows your clusters and ships work via Open Cluster Management, BindingPolicies that link what to where, the controllers that carry objects to execution clusters, and the status machinery that gathers results back into one fleet-wide view.
