CloudNativePG: Robust, Self-Healing PostgreSQL on Kubernetes

CloudNativePG is an open-source Kubernetes operator for PostgreSQL, which has officially been accepted into the Cloud Native Computing Foundation (CNCF) Sandbox.

CloudNativePG manages the full lifecycle of PostgreSQL clusters, configured with a primary/standby setup using native streaming replication for high availability. It is fully declarative and Kubernetes-native. The operator avoids StatefulSets, managing Pods and PersistentVolumeClaims directly. This gives it granular control over storage, instance lifecycle, and automated failover procedures.

We will cover its core design philosophy and key features—including automated deployment, self-healing, and integrated backup/recovery. We will also demonstrate how easy it is to spin up, manage, and scale robust PostgreSQL clusters using CloudNativePG.
