Creating the Cookbook

/Users/vimtaku/vm/myface% berks cookbook myface --foodcritic
      create  myface/files/default
      create  myface/templates/default
      create  myface/attributes
      create  myface/definitions
      create  myface/libraries
      create  myface/providers
      create  myface/recipes
      create  myface/resources
      create  myface/recipes/default.rb
      create  myface/metadata.rb
      create  myface/LICENSE
      create  myface/README.md
      create  myface/Berksfile
      create  myface/Thorfile
      create  myface/chefignore
      create  myface/.gitignore
         run  git init from "./myface"
      create  myface/Gemfile
      create  myface/Vagrantfile

クックブックのスケルトンテンプレートを、 myface っていう名前で作成した。

Prepare your virtual environment
- vendor/bundle にインストールする設定をやってなかったらやっておいたほうが良いかも
  - http://qiita.com/toshiwo/items/4e7c82852f3e14bf5a1d
- bundle install
Starting your virtual machine
- とりあえず言われたとおりにやってみろってことなのでやってみる

   the box yourself. Otherwise Vagrant will attempt to download the

実行されているのは Vagrantfile の中に含まれていた run_list のところのリストだった
cent os とか書いているところは自分の好きな感じで設定できるよとのこと
このへんは知ってるけど不安定とかになったら vagrant destroy とかで消せるよとのこと
Deploying with Artifact Deploy
- myface っていうスーパークールな sns アプリ作ってやろうぜとのこと
  - Artifact Deploy は LWRP を deploy するためのもの!
    - LWRP はこちらを参照 -> http://sssslide.com/speakerdeck.com/kentaro/chef-lwrp
- vim で編集.

/Users/vimtaku/vm/myface/myface% vim recipes/default.rb

artifact_deploy "myface" do
  version "1.0.0"
  artifact_location "http://dl.dropbox.com/u/31081437/myface-1.0.0.tar.gz"
  deploy_to "/srv/myface"
  owner "myface"
  group "myface"
  action :deploy
end

provision command でもう一回 chef の provision を実行する。
berkshelf vagrant plugin の魔法によって依存関係を勝手に解決してくれる!

期待通りにエラッた
- 俺らは全然 artifact_deploy はいらない
- chef client が必要としているだけ
- 俺らは LWRP が必要だっていうのを俺らの cookbook に教えていないから教えてやる
Working with cookbook metadata
- metadata.rb に教えてやる必要がある。
  - このファイルは結構初心者が見落としがちなんだけど結構大事なんだぜ
  - metadata.rb は Rubygems で言う gemspec みたいなやつで依存関係を記述する奴で
    - name attribute で名前とか
    - version attribute でバージョンとか
    - depends 定義で依存する cookbooks の記述とか
    - conflict 定義で conflict する奴とか
    - maintainer attribute でメンテナとか
    - maintainer email とか
    - license 情報とか
    - long_description を使って description とかをかける!
- 全部の属性は必要ない
- けど attribute を空にするのはやめておけとのこと
追記してbundle exec vagrant provision を実行
ユーザ追記とかして
Using Berkshelf to gather dependencies
どっから dependencies を解決しているのか
metadata.rb をみていろいろやる
capistrano っぽいディレクトリ構成で deploy
Refactoring into attributes
- attributes/default.rb に記入

default[:myface][:user] = "myface"
default[:myface][:group] = "myface"

group "#{node['myface']['group']}"

user "#{node['myface']['group']}" do
  group "#{node['myface']['group']}"
  system true
  shell "/bin/bash"
end

artifact_deploy "#{node['myface']['group']}" do
  version "1.0.0"
  artifact_location "/tmp/myface-1.0.0.tar.gz"
  deploy_to "/srv/myface"
  owner "#{node['myface']['user']}"
  group "#{node['myface']['group']}"
  action :deploy
end

artifact_location に /tmp 指定してるのは回線事情があって wget したやつをおいておいた.
うまく行った。書き方をちゃんとしないと validation で引っかかるので注意。
Idempotent recipes
- レシピの冪とう性について書かれている
- not_if とかないと
Configuring the application server
- depends “tomcat”, “~> 0.11.0” を metadata.rb に追加する
- include_recipe “tomcat” を recipes/default.rb に追加する
- provision
include_recipe versus a Role with a run_list
- スパイダーマンより、大いなる力には、大いなる責任が伴う
- ポートフォワーディングの設定
  - config.vm.network :forwarded_port, guest: 8080, host: 9090
Configuring Tomcat users
- したがってやったらできた。
- /myapp はなぜか動かない
- まぁでもとりあえず受けれるところまで行ければおkなのでここまでとする
その下は
- もっと attribute で可変にするところとか
- database の LWRP を使う例とかi が書いてある
これが便利

require 'json'

file "/tmp/dna.json" do
  content JSON.pretty_generate(node)
end
