Overview

Here is an example shared configuration for knife. You can drop this off in your chef-repo/.chef/ directory, and multiple developers can use the same knife configuration to interact with more than one Chef server, or the Opscode platform.

By using Bash functions and environment variables we can change the chef server, which knife is configured to use, on the fly.

NOTE: knife will probably ignore your ~/.chef/knife.rb once you begin using a shared knife.rb in your chef-repo directory.

# 
#  Need to move your initial ~/.chef to ~/.chef-ENV 
# 
alias prod="rm ~/.chef; ln -sf ~/.chef-prod ~/.chef; export CHEF_ENV=prod"
alias dev="rm ~/.chef; ln -sf ~/.chef-dev  ~/.chef; export CHEF_ENV=dev"

function knife_env {
  if [ -e ~/.chef ] ; then
    # gls on osx/homebrew assumes you have installed gnu fileutils. change to ls on linux 
    echo `gls -dl  --indicator-style=none ~/.chef | awk -F- '{print $5}'`

# Knife Configuration File.
#
# This is a Ruby DSL to set configuration parameters for Knife's
# general options. The default location for this file is
# ~/.chef/knife.rb. If multiple Chef repositories are used,
# per-repository configuration files can be created. A per repository
# configuration file must be .chef/knife.rb in the base directory of
# the Chef repository. For example,
#
#     ~/Development/chef-repo/.chef/knife.rb

#
# 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/

# To make this work properly with RVM, you should create a wrapper for the app's gemset unicorn.
