Data On Kubernetes, Deploying And Running PostgreSQL And Patterns For Databases In a Kubernetes Cluster.
summary
Cloud Native PostgreSQL runs as a Kubernetes operator that directly manages PVCs instead of StatefulSets, pairs with a CSI-plugin for local NVMe and storage replication, and exposes commands like kubectl cnpg status and cnpg destroy for instance control. Demo on EKS (i3en NVMe) shows ~30k IOPS, storage-layer replication recovers a terminated node automatically while Postgres-level replication requires operator-driven resync, kube timers (~300s) affect RTO, and volume snapshots vs WAL archiving give different RPO/RTO tradeoffs.
