Stolon Helm Chart

Modified by GmodStore

Modified by GmodStore due to the superuserPassword and replicationPassword secrets not being read from Rancher answers, based on the official helm chart for stolon.

---

• Installs Stolon (HA PostgreSQL cluster)
• Based on lwolf/stolon-chart and stolon examples

TL;DR;

$ helm install stable/stolon

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/stolon

Backend

Kubernetes is the default store backend. consul, etcdv2 or etcdv3 can also be used as the store backend.
