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

Answer 1

So I was able to solve this problem. It does indeed want a hash, but it wants it to be a subset of the Mixlib::CLI class. So, this is the code needed to create a client via knife programmatically:

    class MyCLI
      include Mixlib::CLI
    end

    #Add the option for disable editing. If you look in knife help, it's --disable-editing
    MyCLI.option(:disable_editing, :long => "--disable-editing", :boolean => true)

    #instantiate knife object and add the disable-editing flag to it
    knife = Chef::Knife.new
    knife.options=MyCLI.options

    #set up client creation arguments and run
    args = ['client', 'create',  'new_client', '--disable-editing' ]  
    new_client = Chef::Knife.run(args, MyCLI.options)

It's not the most elegant solution, but it does use knife via the command line and saves someone from have to use a system call to use it.
