Deploy PostgreSQL on Kubernetes using the CloudNativePG operator, which automates cluster provisioning, failover, and management. Install the operator, apply a Cluster manifest specifying instance count and storage, then monitor readiness with kubectl. This approach handles automated failover and reduces manual HA configuration.

CloudNativePG is a Kubernetes operator that manages PostgreSQL clusters natively within Kubernetes. It simplifies deployment, automates failover, enforces connection secret management, and handles backup configuration—eliminating manual provisioning complexity for production and development environments.

Yes. CloudNativePG operator provides built-in backup and recovery workflows. Configure automated backups through the Cluster manifest, then restore from snapshots using kubectl commands. This supports both production workloads and local development scenarios.

No. CloudNativePG operator automates failover within your Kubernetes cluster. When a PostgreSQL instance fails, the operator detects the outage and promotes a replica automatically, eliminating manual intervention for high-availability deployments.

You need a running Kubernetes cluster, kubectl access, and sufficient storage resources. The operator installation is enforced as part of the deployment process. No additional PostgreSQL client tools are required—all management occurs through Kubernetes manifests and kubectl.

Yes. CloudNativePG supports local Kubernetes development environments. Spin up a single or multi-node PostgreSQL cluster locally with the same operator and manifests used in production, enabling consistent testing and development workflows.
