Development in Docker

Overview

This page describes how to develop, build and test Ambari on Docker. 

In order to build Ambari, there are a quite few steps to execute. 

This is NOT meant for running production level Ambari in Docker (though you can run Ambari and deploy Hadoop in a single Docker container for testing purpose) 

(This is not only about Jenkins slaves but think it is your laptop)

First, we will make a Docker image that has all third party libraries Ambari requires. 

Second, prepare your code on Docker host machine. It can be trunk or a branch, or your developing code or with a patch applied. Note that your code does not reside inside of Docker container, but on the Docker host and we link it by Docker volume (like mount)

And you are ready to go!

Source code

This code has been migrated to Ambari trunk.

Requirements

There are a few system requirements if you want to play with this document.

• Docker https://docs.docker.com/#installation-guides

Create Docker Image

First thing first, we have to build an Docker image for this solution.

git clone https://github.com/apache/ambari.git
cd ambari
docker build -t ambari/build ./dev-support/docker/docker

Unit Test

For example our unit test Jenkins job on trunk runs on Docker.

Deploy Hadoop

Run only ambari-server

Run only ambari-server and ambari-agent
