vagrant

 # vagrant my setting
VAGRANTFILE_API_VERSION = "2"
box_name = "centos64"
box_url  = "https://s3.amazonaws.com/itmat-public/centos-6.3-chef-10.14.2.box"
ip       = "192.168.33.10"
ram      = "1024"
hostname = "v_dev"
owner    = "vagrant"
group    = ""

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.box     = box_name
  config.vm.box_url = box_url
  # config.vm.host_name = hostname + '.' + domain
  config.vm.network :private_network, ip: ip

  config.vm.provider :virtualbox do |vb|
    vb.customize [
      "modifyvm", :id,
      '--name'  , hostname,
      '--memory', ram
    ]
	# IPv6とDNSでのネットワーク遅延対策で追記
    vb.customize ["modifyvm", :id, "--natdnsproxy1", "off"]
    vb.customize ["modifyvm", :id, "--natdnshostresolver1", "off"]
  end

  config.vm.synced_folder "./", "/var/www",
    :nfs   => false,
    :owner => owner,
    :group => group,
    :mount_options => ["dmode=775,fmode=775"]

 # chef installed check plugin exsist
 # config.omnibus.chef_version = :latest
 # config.berkshelf.enabled = true

 # chef solo run
  config.vm.provision :chef_solo do |chef|
    chef.run_list = ["cookbook_name"]
  end

chef solo (自分自身にのみ実行する)

用語

• knife (実行者)
• CookBook (gemみたいなライブラリ集)
• Recipe (実行コマンド集)
• Brekshelf

Chef にはいくつかの抽象化するための要素があり、構築手順の汎用性を高めることができます。つまり1つの Cookbook をいろいろな OS、いろいろな設定に使いまわすことができるのです。

そこで、いろんな人が作った Cookbook を使いまわすために RubyGems に対する Bundler のような Cookbook 管理ツールがあります。それが Berkshelf です。

作法

cookbooks

汎用的なcookbooksを配置する場所

site-cookbooks

対象環境固有のcookbookを配置する場所
