NATS Streaming Server on Kubernetes

This project uses official nats-streaming image and a Helm chart to run NATS Streaming Server in the Kubernetes cluster. The NATS Streaming Server can run in either fault tolerance or high availability mode. See the config below. See https://github.com/nats-io/nats-streaming-server for details.

The project is forked from https://github.com/canhnt/k8s-nats-streaming to use with dynamic provisioning volumes.

Requirements

• GKE with Kubernetes v1.8.0 or later.
