SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Provision CNPG Postgres clusters on Kubernetes using GitOps to achieve repeatable, auditable deployments.

Core Features & Use Cases

GitOps-powered CNPG deployments: declarative cluster creation, upgrades, backups, and PITR.
Cross-environment support: managed cloud (GKE + Workload Identity) and self-hosted (K3s/bare-metal) with vector extension and network-policy guidance.
Use Case: clone prod to dev, enable pgvector, wire backups, and enforce default-deny policies with structured references.

Quick Start

Create a new CNPG cluster by applying the manifests in this skill to your Kubernetes cluster.

FAQPage Schema

How do I deploy a Postgres cluster on Kubernetes using GitOps?▼

You can deploy a Postgres cluster on Kubernetes using GitOps by applying declarative manifests through Flux and Kustomize. This approach enables repeatable, auditable cluster provisioning, upgrades, and backups without manual kubectl commands.

Can I use CloudNativePG (CNPG) with managed Kubernetes like GKE?▼

Yes, CloudNativePG works with managed Kubernetes environments like GKE using Workload Identity, as well as self-hosted clusters like K3s. It supports configuring backups, Point-in-Time Recovery (PITR), and pgvector across these different infrastructure platforms.

What do I need to set up before provisioning a CNPG Postgres cluster?▼

Before provisioning a CNPG Postgres cluster, you need Flux and Kustomize for GitOps deployment, SOPS-encrypted secrets for sensitive data, and proper storage configurations. These prerequisites ensure secure, declarative cluster creation and management.

Does CNPG support pgvector and network policies on Kubernetes?▼

Yes, CNPG supports enabling the pgvector extension for vector operations and provides NetworkPolicy guidance to enforce default-deny security policies. This ensures your Postgres cluster is both AI-ready and secure within your Kubernetes environment.

How do I clone a production Postgres cluster to a dev environment?▼

You can clone a production Postgres cluster to a dev environment using declarative GitOps manifests. This process is supported by CloudNativePG configurations, allowing you to replicate data while managing backups and Point-in-Time Recovery (PITR) settings.

What is the best way to configure backups and PITR for Postgres on Kubernetes?▼

The best way to configure backups and PITR for Postgres on Kubernetes is through CloudNativePG's GitOps manifests. It supports both inline and plugin-based backup configurations, ensuring reliable data recovery and auditable deployment across managed or self-hosted clusters.
