The Zalando Postgres Operator enables easy deployment of high‑availability PostgreSQL clusters on Kubernetes using Patroni, managed entirely through CRDs, supporting rolling updates, sidecar monitoring, and seamless CI/CD integration without direct API calls.
This guide walks you through prerequisites, configuration, and deployment options (manual, Kustomize, Helm) for the Zalando Postgres Operator on a local Kubernetes environment, then shows how to verify the operator, deploy its UI, create and connect to a Postgres cluster, and safely delete it.
The Crunchy Data Postgres Operator (PGO) extends Kubernetes to provide a cloud‑native, highly available PostgreSQL platform with features such as automated provisioning, disaster recovery, TLS encryption, monitoring, user management, upgrade handling, advanced replication, cloning, connection pooling, affinity, scheduled backups to S3/GCS, multi‑namespace support, and extensive customizability across major Kubernetes distributions.
