Docker Apache NiFi -

This is an unofficial Apache NiFi Docker image

Base image

Apache NiFi requires a Java runtime. Starting with the 0.4.0 release, I am producing multiple images that each use a different base Java images.

Both the 0.3.0 and 0.2.1 versions use java/8 as their base image.

Latest release and image

The latest version of NiFi is the 0.4.0 release (December 11th 2015). The release notes can be found here.

The latest image is the same as the 0.4.0-openjdk-8 image.

Docker Hub

This image is available on Docker Hub at mkobit/nifi.

Testing out NiFi

To run this image and play around with NiFi:

Pull latest image
```
docker pull mkobit/nifi
```

Run image and expose default ports to host.

# --rm : remove container on exit
# -i : interactive
# -t : allocate TTY
# -p : publish each container port to host port. format: ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort | containerPort
docker run -it --rm -p 8080-8081:8080-8081 mkobit/nifi

Go to default local NiFi endpoint in browser - http://localhost:8080/nifi/

Extending

This can easily be used as a base image to create NiFi applications. One way would be to build a NAR with extensions built upon the framework and including it in your own image. I recommend reading the Developer's Guide if you want to head down this route.

Volumes

These are the default locations as specified by the Apache NiFi properties. You can find more information about each of these repositories on the System Administration Guide

$NIFI_HOME/database_repository - user access and flow controller history
$NIFI_HOME/flowfile_repository - FlowFile attributes and current state in the system
$NIFI_HOME/content_repository - content for all the FlowFiles in the system
$NIFI_HOME/provenance_repository - information related to Data Provenance

ListenHTTP Processor

The standard library has a built-in processor for an HTTP endpoint listener. That processor is named ListenHTTP. You should set the Listening Port to 8081 if you follow the instructions above to run this image.

Usage

This image can either be used as a base image for building on top of NiFi or just to experiment with the tool.
