Cloud Native PostGres (CNPG)

Overview

CloudNativePG is a Kubernetes-native PostgreSQL operator that enables robust and production-grade PostgreSQL database management. It simplifies the deployment and lifecycle management of PostgreSQL clusters using native Kubernetes resources.

In KubeDNA, CloudNativePG is the default component for PostgreSQL workloads — allowing users to run stateful database services inside their Kubernetes environment in a secure, scalable, and cloud-agnostic way.

✅ Current Implementation

In the current version of KubeDNA, users can install CloudNativePG via the Operator, which lays the foundation for managing PostgreSQL clusters.

Installation Path:
[Selected Cluster] > Components > CNPG

• Deploys the CloudNativePG Operator only (no database clusters by default).

• Users can manually define PostgreSQL clusters using Kubernetes CRDs (Cluster, Backup, etc.).

• Ideal for teams comfortable writing manifest files or using GitOps pipelines to define databases.

🔜 Upcoming Release – Full HA PostgreSQL Support

In the upcoming release, KubeDNA will introduce full High Availability (HA) PostgreSQL support powered by CloudNativePG, with a user-friendly rollout interface.

🚀 Key Features:

• HA PostgreSQL Clusters:

  • Multi-node PostgreSQL clusters with automated failover

  • Built-in replication using native streaming

  • PodDisruptionBudget and anti-affinity configured for resilience

• One-Click Database Provisioning:

  • Easily deploy and manage PostgreSQL clusters via the KubeDNA UI

  • Choose storage classes, replica counts, backup schedules

• Integrated Backup & Restore:

  • Scheduled backups with support for object storage (e.g., S3, MinIO)

  • Point-in-time recovery (PITR) capabilities

• Monitoring & Observability:

  • Integration with OpenTelemetry and Prometheus for performance metrics

  • Ready-to-use Grafana dashboards in the platform

• Multi-Tenant Ready:

  • Support for namespace-level isolation of databases

  • Optional integration with Vault or KubeDNA secrets for secure credential management

🎯 Use Cases

• Deploying internal application databases

• Self-hosting PostgreSQL for SaaS workloads

• Staging or test environments with real-time scaling

• Running data services in sovereign cloud or on-prem setups

📌 Notes

• The CloudNativePG operator will continue to be available for advanced use cases.

• Users can still use GitOps pipelines to define database clusters declaratively.

• Future releases will support database cloning, scheduled failover, and managed upgrades.
