Module: Awsborn::Chef::Rake

Defined in:
lib/awsborn/rake.rb

Overview

Just add a ‘Rakefile` in the same directory as your server definition file.

require 'awsborn'
include Awsborn::Chef::Rake
require './servers'

You are now able to run ‘rake` to start all servers and run Chef on each of them. Other rake tasks include:

  • ‘rake chef` - Run chef on all servers, or the ones specified with `host=name1,name2`.

  • ‘rake chef:debug` - Ditto, but with chef’s log level set to ‘debug`.

  • ‘rake start` - Start all servers (or host=name1,name2) but don’t run ‘chef`.

You can use ‘server=name1,name2` as a synonym for `host=…`
