This draft turns a raw build note into a practical cluster setup guide: wipe the storage disks carefully, prepare the network, deploy Kubernetes with DeepOps, add MetalLB, and leave the cluster in a state where Ceph and monitoring can be layered on cleanly.
This draft walks through the practical flow for connecting an existing Ceph cluster to Kubernetes with Rook: collect the monitor data and FSID, generate external-cluster resources, import them into the target cluster, install the Rook operator, and verify that the external Ceph connection is healthy.
This draft keeps the preparation side of a Ceph build intact: identify the right storage nodes, inspect the disk inventory carefully, wipe only the intended devices, and make sure the nodes have the network path they need before the actual Ceph deployment begins.
