chef-nutcracker's Introduction

nutcracker Chef Cookbook

This cookbook installs twitter/twemproxy (nutcracker).

It just downloads source from Github, compiles and installs. You can set up custom configure flags or compiler environment variables via attributes if needed.

NOTE: The configuration of this has changed significantly from version 1.0 to version 1.1.
We are no longer using data_bags to configure instances, we're using attributes now.

Installation

Add a submodule dependency to your project, I'm assuming here that chef/cookbooks/ is the sub-directory where you want your cookbook dependencies installed. Whatever path you choose to check it out to, make sure that is in your cookbook search path.

$ git submodule add https://github.com/vube/chef-nutcracker chef/cookbooks/chef-nutcracker

In your metadata.rb

depends "chef-nutcracker"

In your recipe.rb

include_recipe "chef-nutcracker"

Configuration

To configure this you must configure the node['nutcracker']['instances'] attribute.

Examples

Single nutcracker instance

default['nutcracker']['instances']['my_instance'] = {
    'port' => 22122,
    'servers' => ['localhost:6375:1', 'localhost:6379:1']
}

Single nutcracker instance using memcache

default['nutcracker']['instances']['my_instance'] = {
    'port' => 22122,
    'redis' => false,
    'servers' => ['localhost:6375:1', 'localhost:6379:1']
}

Multiple nutcracker instances on different ports

default['nutcracker']['instances']['my_instance_1'] = {
    'port' => 22122,
    'status_port' => 8622,
    'servers' => ['localhost:6375:1', 'localhost:6379:1']
}
default['nutcracker']['instances']['my_instance_2'] = {
    'port' => 33233,
    'status_port' => 8623,
    'servers' => ['localhost:7486:1', 'localhost:7480:1']
}
