Distributed storage with Rook
summary
Rook runs Ceph inside Kubernetes via CRDs so storage is containerized and managed by an Rook operator + agent; demo provisions a 20GB PVC from a Ceph pool, mounts it into a BusyBox pod and survives pod restarts, scales a GitLab web tier from 1 to 5 replicas on CephFS, and provisions an Elasticsearch cluster on Rook block devices. Supports BlueStore and FileStore backends, NFS is in progress, and at least one small production deployment exists.
