Kubegres is an open-source Kubernetes operator allowing to deploy a cluster of PostgreSql instances with data replication enabled out-of-the box. It brings simplicity when using PostgreSql considering how complex managing stateful-set's life-cycle and data replication could be with Kubernetes.

Kubegres has the following features:

  • It creates a cluster of PostgreSql servers with data replication enabled: it creates a Primary PostgreSql pod and a number of Replica PostgreSql pods and replicates primary's database in real-time to Replica pods.

  • It manages fail-over: if a Primary PostgreSql crashes, it automatically promotes a Replica PostgreSql as a Primary.

  • It has a data backup option allowing to dump PostgreSql data regularly in a given volume.

  • It provides a very simple YAML with properties specialised for PostgreSql.

  • It is resilient, has over 55 automatized tests cases and has been running in production.

  • It works with the PostgreSql containers created by the Docker Official Images team: it does not ship nor require a custom Docker image to work.

It is Open-Source and available on GitHub: https://github.com/reactive-tech/kubegres
