#5: In Kubegres yaml, we added the field 'imagePullSecrets' so that we can pull custom Postgres images from a private repo. The images have to be compatible with PostgreSql containers
A big thanks to the community for their kind feedback!
Version 1.1 is compatible with Kubegres version 1.0
To install and use it, please see: Getting started
Kubegres version 1.0 is open source and it provides the following features:
It creates a cluster of PostgreSql servers with Streaming 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. Kubegres uses the standard PostgreSql libraries to manage replication and failover and it does not require a custom Docker image with a set of third party libraries.
It is portable because compatible with any Docker images which derive from the PostgreSql containers
