Auto-enable Local HTTP Caching in Test Kitchen

Note: total experiment and hack, looks nasty, could be awesome:

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?)

Run with HTTP Caching Proxy

Simply start up polipo in the foreground in a terminal/tmux/screen session with: ~/bin/polipo-start. In your Test Kitchen project verify that caching is enabled by running kitchen list --debug and look for the http_proxy and chef_omnibus_url config options.

kitchen.local.yml

require 'socket'

def local_ip
  @local_ip ||= begin
    # turn off reverse DNS resolution temporarily
    orig, Socket.do_not_reverse_lookup = Socket.do_not_reverse_lookup, true

    UDPSocket.open do |s|
      s.connect '64.233.187.99', 1
      s.addr.last
    end
  ensure
    Socket.do_not_reverse_lookup = orig
  end
end

def local_port ; 8123 ; end
def http_proxy_url ; "http://#{local_ip}:#{local_port}" ; end

def proxy_running?
  socket = TCPSocket.new(local_ip, local_port)
  true
rescue SocketError, Errno::ECONNREFUSED,
  Errno::EHOSTUNREACH, Errno::ENETUNREACH, IOError
  false
rescue Errno::EPERM, Errno::ETIMEDOUT
  false
ensure
  socket && socket.close
