PGO, the Postgres Operator from Crunchy Data, gives you a declarative, GitOps-friendly way to run production PostgreSQL on Kubernetes. Within minutes you can have a fully operational cluster with high availability, automated backups, TLS encryption, and connection pooling — all managed through a single Kubernetes custom resource.

Quickstart

Deploy your first PostgreSQL cluster in under five minutes using Kustomize.

Architecture

Understand how PGO components work together to deliver production Postgres.

Create a Cluster

Learn all the options for provisioning and customizing a PostgresCluster.

Custom Resource Reference

Full reference for the PostgresCluster, PGUpgrade, and PGAdmin CRDs.

​
Why PGO?

PGO automates the operational complexity of running PostgreSQL at scale on Kubernetes, so you focus on your application instead of your database infrastructure.

High Availability

Automatic failover via Patroni with distributed consensus. Standby clusters across multiple Kubernetes environments.

Disaster Recovery

Full, incremental, and differential backups via pgBackRest. Store to S3, GCS, Azure, or local volumes.

Connection Pooling

Built-in pgBouncer integration to efficiently manage thousands of application connections.

Monitoring

Out-of-the-box Prometheus metrics, Grafana dashboards, and Alertmanager rules via pgMonitor.

TLS Everywhere

All connections are encrypted by default. Bring your own certificates or use PGO-managed PKI.

Major Version Upgrades

Perform in-place major Postgres version upgrades with the PGUpgrade custom resource.

​
Get started

1

Install PGO

Deploy the operator to your Kubernetes cluster using Kustomize or Helm.
2

Create your first cluster

Apply a PostgresCluster manifest to provision a production-ready Postgres cluster.
3

Connect your application

Retrieve the connection credentials from the automatically generated secret and connect your application.

​
Supported platforms

PGO runs on any CNCF-conformant Kubernetes distribution, including Amazon EKS, Google GKE, Microsoft AKS, Red Hat OpenShift, Rancher, and VMware Tanzu.
PGO requires Kubernetes 1.19 or later. See the supported platforms reference for the full compatibility matrix.
