What Hacker News says
3 sourcesKubegres version 1.1 is available
We are pleased to announce the availability of Kubegres version 1.1 with the following features based on the feedback of the community:
- Kubegres will only apply "pod anti-affinity" if there are sufficient nodes on a Kubernetes cluster. Otherwise, it will will deploy some PostgfeSql instances on the same node(s).
- In Kubegres yaml, add the field 'imagePullSecrets' so that we can pull images from a private repo
A big thanks to the community for their kind feedback.

2 points · Open discussionKubegres is a Kubernetes operator for PostgreSQL
Kubegres, https://www.kubegres.io , 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 official PostgreSql docker image: it does not ship nor require an additional Docker image to work. Just install the Kubernetes controller once and deploy as many PostgreSql clusters as you need by simply deploying the official container of the PostgreSql community.
Kubegres was developed by Reactive Tech Limited, https://www.reactive-tech.io/ and Alex Arica as the lead developer.
It is Open-Source and available on GitHub: https://github.com/reactive-tech/kubegres
