Knife config for Multiple Chef Environments

multi_env_knife_config

#
# This is an example of a knife.rb configuration that uses yml and a 
# simple env var (CHEF_ENV) to manage multiple hosted Chef environments.
#
# Example usage:
# export CHEF_ENV=evnironment_01
# knife status
# 
# Based on: http://blog.blankpad.net/2010/09/28/multiple-knife-environments---the-return/
#
# The directory structure will look something like this:
# .chef/
# ├── environment_01
# │   ├── checksums
# │   ├── config.yml
# │   ├── environment_01-validator.pem
# │   └── user.pem
# ├── environment_02
# |   ├── checksums
# │   ├── config.yml
# │   ├── environment_02-validator.pem
# │   └── user.pem
# └── knife.rb


# Example environment_01 config.yml:

node_name: "user"
server: "https://api.opscode.com/organizations/environment_01"
validator: "environment_01-validator"


# Example knife.rb file parses the config.yml based on the value of CHEF_ENV:

require 'yaml'

CHEF_ENV = ENV['CHEF_ENV'] || "your_environment"
current_dir = File.dirname(__FILE__)
env_config = YAML.load_file("#{current_dir}/#{CHEF_ENV}/config.yml")

log_level                :info
log_location             STDOUT
node_name                env_config["node_name"]
client_key               "#{current_dir}/#{CHEF_ENV}/#{env_config["node_name"]}.pem"
validation_client_name   env_config["validator"] || "chef-validator"
validation_key           "#{current_dir}/#{env_config["validator"]}.pem"
chef_server_url          env_config["server"]
cache_type               'BasicFile'
cache_options( :path => "#{current_dir}/#{CHEF_ENV}/checksums" )
cookbook_path            ["#{current_dir}/../chef-repo/cookbooks", "#{current_dir}/../chef-repo/site-cookbooks"]

Thanks, exactly what I was looking for.
