summary

Rook is a Kubernetes operator that runs Ceph to provide block, shared filesystem and S3 object storage and claims production scale with examples: a reported cluster of 250 nodes, 1,800 OSDs, ~5.2 PB and Ceph public telemetry reaching exabytes; tuned setups hitting 1 TB/s reported throughput. Releases add features: 1.16 (Dec 2024) adds namespace mirroring, S3 storage-class/audit logs and multi-network; CSI supports RBD, CephFS, NFS with snapshots, PVC encryption, replication and planned CSI operator default + 1.17 (Apr 2025). Topology-aware PDBs and documented recovery steps exist after full-node imaging.
