##Overview

The kafka module for managing the installation and configuration of Apache Kafka

Puppet Forge Build Status

##Module Description

The Kafka module for managing the installation and configuration of Apache Kafka: it's brokers, producers and consumers.

##Setup

###What kafka affects

Installs the Kafka package and creates a new service.

###Beginning with Kafka

To successfully install Kafka using this module you need to have Apache Zookeeper already running at localhost:2181. You can specify another Zookeeper host:port configuration using the config hash of the kafka:broker class.

The default configuration installs Kafka 0.8.2.1 binaries with Scala 2.10

  class { 'kafka': }

If you want a Kafka broker server that connects to zookeeper listenting on port 2181:

	class { 'kafka::broker':
	  config => { 'broker.id' => '0', 'zookeeper.connect' => 'localhost:2181' }
	} 

##Usage

You can specify different Kafka binaries packages versions to install. Please take a look at the different Scala and Kafka versions combinations at the Apache Kafka Website

Installing Kafka version 0.8.2.2 with scala 2.10

We first install the binary package with:

	class { 'kafka':
		version => '0.8.2.2',
		scala_version => '2.10'
	}

Then we set a minimal Kafka broker configuration with:

	class { 'kafka::broker':
	  config => { 'broker.id' => '0', 'zookeeper.connect' => 'localhost:2181' }
	}
