Deploy PostgreSQL on Kubernetes with high availability using the CloudNativePG operator, which automates cluster provisioning, failover, and backup configuration. Install the operator via Helm, apply a Cluster manifest, and the system manages replication and failover automatically.

CloudNativePG is a Kubernetes operator that manages production-grade PostgreSQL clusters natively. It provides automated failover, high availability, secret management, and backup configuration without requiring external tools, making PostgreSQL cloud-native on Kubernetes.

Yes, CloudNativePG v1.28+ supports production deployments with automated failover, high availability, connection secret management, and backup configuration. It works across production, development, and test Kubernetes environments.

After deploying a PostgreSQL cluster with CloudNativePG, configure backup policies and connection secrets through the Cluster manifest. The operator manages secret creation and backup scheduling automatically within your Kubernetes environment.

Helm is supported but not required. You can deploy CloudNativePG using YAML Cluster manifests directly via kubectl. Both methods work with Kubernetes access to install the operator and provision PostgreSQL clusters.

CloudNativePG automates failover when a node fails. The operator detects the failure, promotes a standby replica, and restores the cluster to full availability automatically, eliminating manual intervention.
