Deploying Stand-alone Ceph and Integrating with K8/OpenShift and OpenStack
summary
Shows how to build a standalone Ceph cluster with cephadm/ceph-ansible, bootstrap via preflight and registry.json, and integrate it successfully with OpenStack and OpenShift. Provides concrete numbers: minimum three monitors, default replica=3 and recommendation of 4 nodes for replica=3; separate public and backend networks to avoid replication overflow. Demonstrates creating RBD, RGW and erasure‑coded pools (multipart RGW pools must be replicated), using external-ceph.yaml plus `openstack overcloud deploy` and the OpenShift Data Foundation operator with the Python extractor — integration works.
