Karmada: Multi-Cluster Kubernetes Orchestration

by Shriira Press

Karmada (Kubernetes Armada) is a multi-cluster and multi-cloud Kubernetes orchestration system — manage many clusters as one fleet, deploying and orchestrating applications across clusters from a single control plane. This free book teaches it from the ground up: the multi-cluster problem and what Karmada is, why organizations run many clusters and the management challenges, Karmada's architecture (the Kubernetes-compatible control plane and member clusters), registering clusters (Push vs Pull), propagation (distributing workloads with PropagationPolicy), cross-cluster scheduling (placement, spread constraints), overrides (per-cluster customization), multi-cluster services and networking (cross-cluster communication), failover and high availability (surviving cluster/region/cloud failures, disaster recovery), and operating Karmada in practice. Ten focused chapters with clear diagrams that demystify multi-cluster orchestration — turning many Kubernetes clusters into one resilient, globally-distributed, orchestrated fleet.
