invoking knife in a ruby class

Question

I\'d like to create a nice wrapper class around knife to allow a program to run knife commands in a readable manner. I\'m currently trying to use the knife.rb file in the chef

You could refer to following solution: http://lists.opscode.com/sympa/arc/chef/2011-08/msg00014.html

    require 'rubygems'
    require "chef"
    require "chef/knife/core/bootstrap_context"
    require 'chef/knife'
    require 'chef/knife/ssh'
    require 'net/ssh'
    require 'net/ssh/multi'
    require 'chef/knife/bootstrap'

    Chef::Config.from_file(File.expand_path('~/.chef/knife.rb'))
    kb = Chef::Knife::Bootstrap.new
    kb.name_args = "some.host"
    kb.config[:ssh_user] = "ubuntu"
    kb.config[:run_list] = "role[test]"
    kb.config[:use_sudo] = true
    kb.run
