cloudnative-pg

Introduction

The cloudnative-pg controller is leveraged to deploy multiple PostgreSQL databases which are used for various services within the cluster.

It’s entirely declarative, and directly integrates with the Kubernetes API server to update the state of the cluster — for this reason, it does not require an external failover management tool. — https://cloudnative-pg.io
