POC Nifi (cluster) and Zookeeper integration with Docker

This POC is using Docker image from nifi-docker-cluster.

Target

• Run Apche Nifi clustering mode (Zookeeper as discovery service) with docker/docker-compose.

Requirements

• Docker version 1.12.3
• Docker Compose version 1.8.1

Basic docker up

1. Up docker-compose

   $ docker-compose up -d
   

2. Browse Web UI for components:

• Apache Nifi: http://localhost:8080/nifi/

3. Template

• pull-from-twitter-farden-hose.xml: this flow demonstrates how to config twitter streaming.
• simple-httpget-route.xml: this flow demonstrates how to crawl a web server and save result to file.

Known Issues

• Cannot use docker-compose scale for nifi-nodes, assuming can solve this issue when deploy to multiple host.
