Rook: Cloud-Native Storage Orchestration

by Shriira Press

Rook is a storage operator that turns Ceph — powerful but complex distributed storage — into something Kubernetes manages automatically, so you can run production-grade block, file, and object storage inside your cluster, declaratively, without becoming a storage expert. This free book teaches it from the ground up: distributed-storage fundamentals and the three storage types, Ceph's architecture (OSDs, monitors, managers, MDS, RGW), the operator pattern and Rook's architecture, deploying a Ceph cluster, block storage for databases, shared file (CephFS) and S3 object storage, consuming storage via CSI and PVCs, data protection and self-healing recovery, and operating Rook/Ceph in production (capacity, monitoring, upgrades). Ten focused chapters with clear diagrams that show how to bring automated, self-healing, cloud-independent storage into Kubernetes.
