Dynamic Workloads need Dynamic Storage - using rook-ceph with k8s
summary
Demonstrates building a container‑native Ceph cluster using the Rook operator and rook‑ceph on Kubernetes/OpenShift, provisioning multi‑AZ EBS volumes and creating storage classes that return block, file and object. Dynamic provisioning finishes in seconds versus native EBS 3–5 minutes, reclaiming storage when pods die, and enabling RWX mounts so three replicas share one filesystem. Uses the CSI driver as the default, supports external Ceph, and the demo boots, switches storage classes and serves files successfully.
