A step-by-step guide for automating Ceph RGW (RADOS Gateway) user management on OpenShift using a GitOps approach. The workflow uses the rook-ceph operator to translate Kubernetes CRDs into actual S3 user accounts and quotas on an external Ceph cluster, with OpenShift GitOps (ArgoCD) as the declarative engine and the External Secrets Operator (ESO) to securely propagate S3 credentials into developer namespaces. The guide covers connecting rook-ceph to an external Ceph cluster, structuring a Git repository with CephObjectStoreUser manifests, configuring ArgoCD permissions, setting up cross-namespace secret delivery via ESO, and validating quota enforcement with a Python-based bucket filler test. A key finding is that Ceph RGW quota enforcement is a soft limit, not a hard stop.
