Parallelization in Chef Recipes

Chef presently runs the resources in a recipe serially, one after the next. In this proposal, user-selected groups of resources will run their actions in parallel.

MVP (Minimum Viable Product) Features

in_parallel

To run a group of resources in parallel, you write it this way:

# I'm sure this can all be replaced with a one liner, buried deep in chef somewhere.
# Actually, probably Chef::Client.

require 'json'
require 'chef'
require 'chef/application/solo'
require 'chef/knife/deps'

def setup_node(environment, name, node_config_path)
  Chef::Config[:config_file] = ".chef/knife.rb"

Setup

• Drop the kitchen.local.yml into $HOME/.kitchen/config.yml
• Install polipo (with Mac: brew install polipo, with Ubuntu: apt-get install polipo)
• Drop polipo-start and polipo-console somewhere useful (perhaps $HOME/bin?)
