Knife To Ruby

A Chef Knife plugin to print Chef objects (Role/Environment) in ruby code,

$ knife role toruby role_name
name "role_name"

description "my description"

default_attributes({
  "a" => "b"
})

override_attributes({
  "a" => "b"
})

run_list("recipe[cookbook_a]", "recipe[cookbook_b]")

Should be equivalent to knife show role -Fj but for ruby.

Installation

/opt/chef/embedded/gem install knife-toruby

How to Use

knife role toruby [ROLE]
knife environment toruby [ENVIRONMENT]

Chef Objects Supported

• Role
• Environment

Transform .json file to .rb locally

If you want to transform your .json role/environment files locally without uploading them to the chef-server you can do that using this script,

require 'chef/ruby_compat'
require 'chef/knife'
require 'chef/knife/core/object_loader'
require 'json'

loader = ::Chef::Knife::Core::ObjectLoader.new(Chef::Role, nil)
role = loader.load_from("roles", 'MY_ROLE.json')

puts Chef::RubyCompat.to_ruby(role)

Update this script with your file name and if you are using an environment instead of a role. Save this file as something like transform.rb, make sure to have knife-toruby installed in knife and then run the command,

knife exec transform.rb
