kafka cookbook

Installs Kafka v0.8.0, and probably any newer versions.

Based on the Kafka cookbook released by WebTrends (thanks!), but with a few notable differences:

• supports both source and binary releases (>= v0.8.0).
• does not depend on runit cookbook.
• does not depend on zookeeper cookbook, thus it will not search for nodes with a specific role or such, that is left up to you to decide.
• only tested on Vagrant boxes.
• intended to be used by wrapper cookbooks.

Requirements

This cookbook does not depend on any specific cookbooks, but it requires that java is installed on the system, thus the java cookbook is recommended.

Ruby 1.9.3+ and Chef 11.6.0+.

Platform

• CentOS 6.5
• Debian 7.4
• Fedora 20
• Ubuntu 14.04

Might work on other platforms / versions, but these are the ones that are included in .kitchen.yml, so YMMV.

Attributes

In order to keep the README in some kind of manageable state (and thus in sync with attributes), attributes are documented inline (in the attribute files that is).

Attributes concerning configuring of a Kafka broker are to be set under the broker namespace, and one can choose which ever syntax they prefer the most, the following are all valid ways to define broker configuration:

node.default.broker[:log_dirs] = %w[/tmp/kafka-logs]
node.default.broker['log.dirs'] = %w[/tmp/kafka-logs]
node.default.broker.log.dirs = %w[/tmp/kafka-logs]
node.default[:broker][:log][:dirs] = %w[/tmp/kafka-logs]

A warning regarding the "dotted" notation, it doesn't play very well when setting attributes like default.replication.factor or fetch.purgatory.purge.interval.requests due to fairly obvious reasons (default and fetch are also methods).

Refer to the official documentation for the version of Kafka that you're installing.

Recipes

This section describes the different recipes that exists, and how to use them.

default

Includes either source or binary recipe depending on what node.kafka.install_method is set to (:source, :binary).

source

Downloads, compiles and installs Kafka from the official source releases. Defaults to installing v0.8.1.1 of Kafka.

binary

Downloads and installs Kafka from the official binary releases. Defaults to installing v0.8.1.1 of Kafka.
