Simplifying Storage in Kubernetes with Rook-Ceph
summary
Rook bundles Ceph into Kubernetes as a production-ready operator (Rook v1.19 released Jan 2026) that runs on K8s 1.30–1.35 and talks to Ceph 19+, supporting Block (RBD), File (CephFS), Object (RGW) and bucket claims for S3 access. Key specifics: experimental NVMe over Fabrics and multi-Ceph-per-operator support, CSI 3.16 integration, Rados OMAP checkpointing for CSI, change-block-tracking, encryption key rotation, volume-group replication and DR mirroring, and a kubectl rook plugin. Upstream runs ~250-node clusters with ~1,800 OSDs (~5.2 PB), showing it scales in production.
