Rook: Intro and Deep Dive with Ce...
summary
Rook is an operator that deploys and manages Ceph inside Kubernetes, packaging Ceph Quincy v17 with the Ceph CSI 3.6 stack to give block (RBD), file (CephFS), and S3 object via OBCs plus NFS provisioning and wire encryption/compression. Demo uses OpenShift on AWS with GP2 PVCs: starts with three OSDs (3×10 GB = 30 GB), expands to 3×100 GB = 300 GB and then to six OSDs for ~600 GB; operations complete in minutes and upgrades and external Ceph connections are supported.
