ODF & Metro-DR: Multi-Cluster RPO=0 Resilience and Synchronous Storage on OpenShift
OpenShift Data Foundation Metro-DR architecture: synchronous Rook-Ceph RBD mirroring, RamenDR and RHACM declarative orchestration for RPO=0 resilience on stateful and AI workloads.
OpenShift Data Foundation: Rook-Ceph, CSI and Per-Tenant Encryption
ANALYSIS — OpenShift Data Foundation (Rook-Ceph): operator + Ceph daemons + CSI drivers, ceph-rbd / cephfs StorageClasses, cluster-wide or per-StorageClass encryption with HashiCorp Vault as KMS, and namespace-level multi-tenant isolation.
Container Security: Why Your Non-Root Container Drops Its Capabilities (SCC, CRI-O, Kernel)
ANALYSIS — Why CAP_NET_RAW is missing in a non-root container: the SCC → CRI-O → kernel pipeline, the five capability sets (Bnd/Prm/Eff/Inh/Amb), the UID 0 → non-root transition and the real fixes (file capabilities, KEP 2763 ambient capabilities).
