This article describes how to launch Apache NiFi 1.0.0 on docker. To launch Apache NiFi 1.1.0 on docker go here.
During my development of the Json2CSV processor here, I quickly found a need for an environment to test my processor. I don't want to build and install NiFi from my laptop since I need all my applications isolated from each other for ease of maintenance. Docker to the rescue! Similar to how I launch a PyCharm IDE from a docker image here which will rerender back to my laptop. Isolation! I like to keep it simply. Put everything in a Dockerfile and allow myself to quickly launch a NiFi Docker image. Here are the steps to get you up and running
Prerequisites
- Download latest virtualbox from here.
- To run docker containers or build images a docker machine is required. Download docker machine from here.
First pull the prebuilt and complied docker image (https://hub.docker.com/r/sunileman/dockernifi/) by running this command:
docker pull sunileman/dockernifi
Now you have the docker image simply run it
docker run -it --rm -p 8080-8081:8080-8081 sunileman/dockernifi
Here you are exposing ports 8080 and 8081 and mapping to your local ports 8080 and 8081 respectively.
During my development of this docker image I found sometimes virtualbox will not create port-forwarding rules even though I have created them during my docker run.
To simplify this process grab portforward shell script from here.
- Name it portforward.sh
- Verify you can execute script by issuing chmod on it
- then run this command
- ./portforward.sh 8080
- ./portforward.sh 8081
If you do not want to download and execute the script, simply go to virtualbox and create a port forwarding rules for the 8080 and 8081 ports
Your done. Go to localhost:8080/nifi/
To shut down nifi simply hit control+c and nifi will shut down gracefully. That is too easy. Now go build some cool stuff!
