Helm chart to install Stolon (HA PostgreSQL cluster)

About this fork

❗ I am trying to use the stolon chart on minikube, and this fork is about documenting my experiments. So, this is work in progress !

The following sections show the original README.md

Introduction

Stolon is a cloud native PostgreSQL manager for PostgreSQL high availability. It's cloud native because it'll let you keep an high available PostgreSQL inside your containers (kubernetes integration) but also on every other kind of infrastructure (cloud IaaS, old style infrastructures etc...)

Chart is partially based on the statefullset example from the stolon repo

Currently only etcd backend is supported. Etcd is based on chart from incubator with updates to support 1.5 statefulset (PR pending). After it will be merged, etcd will be removed from the source.

Requirements

• Kubernetes 1.5 (for StatefulSets support)
• PV support on the underlying infrastructure
• Helm 2.2.0 (for conditions and flags support)

TODO:

• automate initial stolon cluster creating
• Managed and standalone mode for etcd
• Try to integrate etcd operator
• Add support for consul backend
• Conditional dependencies to be able to use either etcd or consul

Known issues

• etcd from the incubator(and the copy here) has problems with scale down and re-joining fallen pods. #685
