Kubegres is a Kubernetes operator allowing to deploy clusters
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....
Postgres streaming replication cluster for any docker environment
PostgreSQL cluster with High Availability and Self Healing features for any cloud and docker environment (Amazon, Google Cloud, Kubernetes, Docker Compose, Docker Swarm, Apache Mesos)
These are 2 OS definitions and a scheduler script that are designed for the full virtualization of linux and windows systems on Ganeti.
They works good on my KVM-based production environment and provides all that you need in order to create, backup and restore instances.
Note: I was told that it works pretty good even under XEN hypervisor.
