githubのプルリク

どうしたもんかと解決策を探していたところ、プルリクにありましたのでまとめたものです。

Vagrantfile,Berksfileの内容

centos6.5 - 64bitを使用しています。

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|
  # 個人で好きなように
  config.vm.box = "vm_centos_6.5"
  config.vm.box_url = "http://developer.nrel.gov/downloads/vagrant-boxes/CentOS-6.5-x86_64-v20140504.box"

  # Chef
  config.vm.provision "chef_solo" do |chef|

    chef.run_list = [
      "ruby_build",
      "rbenv::system"
    ]

    chef.json = {
      "rbenv" => {
        "global" => "2.2.1",
        "rubies" => [ "2.2.1" ],
        "gems" => {
          "2.2.1" => [
            { "name" => "bundler" }
          ]
        }
      }
    }
  end

end

source "https://api.berkshelf.com"

cookbook 'ruby_build'
cookbook 'rbenv', :git => 'https://github.com/muskox/chef-rbenv'

こんな感じの設定でvagrant upするとエラーが発生します。
chefのバージョンアップにより発生しているようです。

A.cookbookのrbenvを修正する

cookbooks/rbenv/libraries/chef_provider_package_rbenvrubygems.rb

### 追記
require 'etc'
###

class Chef
  module Rbenv
  ...
  end

  class Provider
    class Package
      class RbenvRubygems < Chef::Provider::Package::Rubygems
      
        ...
        
        def install_package(name, version)
          # super
          ### 元の呼び出しをコメント化して、追記
          run_as_user(rbenv_user) { super }
          ###
          rehash
          true
        end

        def remove_package(name, version)
          # super
          ### 元の呼び出しをコメント化して、追記
          run_as_user(rbenv_user) { super }
          ###
          rehash
          true
        end
        
        ...

        # def rehash
        #   rbenv_rehash new_resource do
        #     root_path rbenv_root
        #     user rbenv_user if rbenv_user
        #     action :nothing
        #   end.run_action(:run)
        # end
        
        ### 元のメソッドをコメント化して、追記
        def rehash
          e = ::Chef::Resource::RbenvRehash.new(new_resource.name, @run_context)
          e.root_path rbenv_root
          e.user rbenv_user if rbenv_user
          e.action :nothing
          e.run_action(:run)
        end
        ###
        
      end
    end
  end
end

cookbooks/rbenv/libraries/chef_rbenv_script_helpers.rb

class Chef
  module Rbenv
    module ScriptHelpers
    
      ...

      ### 追記
      def run_as_user(username, &block)
        if username
          user = Etc.getpwnam(username)
          Process.fork do
            Process.uid = user.uid
            block.call
          end
          Process.wait
        else
          block.call
        end
      end
      ###
      
    end
  end
end

B.chefのバージョンを下げる

# config.omnibus.chef_version = :latest
config.omnibus.chef_version = "11.18.6"
