Originally published on DevToolHub, where I keep this guide updated as CloudNativePG evolves.
Running PostgreSQL in Kubernetes used to be a bad idea. StatefulSets were tricky, persistent volumes were unreliable, and failover meant data loss. Most teams defaulted to managed cloud databases and called it done.
That calculus has changed. CloudNativePG — the CNCF-listed PostgreSQL operator — handles high availability, automated failover, Point-in-Time Recovery, connection pooling, and streaming replication out of the box. In 2026 it's the production-grade way to run PostgreSQL on Kubernetes, and the gap between "self-hosted on K8s" and "managed cloud database" has narrowed significantly.
This guide walks through a complete CloudNativePG setup — from operator install to production-ready cluster.
