Kubegres is a Kubernetes operator that allows to deployment one or many clusters of PostgreSQL pods with data replication and failover enabled out-of-the-box. It brings simplicity when using PostgreSQL considering how complex managing a stateful-set's life cycle and data replication could be with Kubernetes. Kubegres is fully integrated with Kubernetes' lifecycle as it runs as an operator written in Go. It is minimalist in terms of codebase compared to other open-source Postgres operators. It has the minimal and yet robust required features to manage a cluster of PostgreSql on Kubernetes. We aim keeping this project small and simple.
Features
- It can manage one or many clusters of Postgres instances
- It creates a cluster of PostgreSql servers with Streaming Replication enabled
- Each cluster of Postgres instances is created using a YAML of "kind: Kubegres". Each cluster is self-contained and is identified by its unique name and namespace
- It creates a Primary PostgreSql pod and a number of Replica PostgreSql pods and replicates primary's database in real-time to Replica pods.
- Documentation available
- 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
