PackerでChef適用済みAMIをサクッと作成する(chef-solo provisionerの活用)
ども、大瀧です。Amazon EC2のテンプレートであるAMI(Amazon Machine Image)の作成が設定ファイルとコマンドラインで簡単にできる、Packerというツールを以前ご紹介しました。
その記事の後半で触れていたchef-solo provisioner(Chef連携機能)が、3日前にようやくmasterにマージされたので試してみました。
chef-solo provisionerとは
Packerは、AWS環境だとEC2インスタンスを作成し(下図1)、設定ファイル(Template)を元に一定の構成を行い(下図2)、そこから新たなAMIを作成できます(下図3)。
chef-solo provisionerは、下図2のEC2インスタンスの構成としてChefのインストールとchef-soloによるcookbooks/recipeを実行する機能を持ちます。Packerおよびchef-solo provisionerは、ChefでEC2を管理するときの従来の懸念事項だった以下が解消できる画期的ソリューションになります！
- Chefの1回目の実行が遅い(ソフトウェアのインストール/ビルドが行われるため)
- あらかじめChefを1回実行したAMIを作ると、AMIの管理が煩雑になる(AMIは1つに統一したい、AMIのバージョンアップに追随したい)
1. ソースからPackerをビルドする
ビルド済みパッケージがリリースされました(バージョン0.3.5)！ダウンロードページからダウンロードし、通常のセットアップで導入できるようになりました。以下のビルド作業は不要です。
本日(2013/08/26)時点では、ビルド済みのリリースパッケージにはまだ含まれていないため、githubのソースから自分でビルドする必要があります。Packerのビルド手順はREADMEのDeveloping Packerを参照してください。GoとMercurialを事前にインストールしておく必要があります。
$ packer -v Packer v0.3.5.dev (99dd3ccec5cf84659fced53f5c7b6a304263e03f) $
2. Cookbookの準備
適用するChefのCookbookを準備します。といっても、Packer向けの特別な設定は必要ありません。今回はBerkshelfでnginxのCommunity Cookbookを用意しました。
$ ls cookbooks/nginx/ Berksfile Gemfile.lock TESTING.md definitions/ metadata.rb CHANGELOG.md LICENSE attributes/ files/ recipes/ CONTRIBUTING.md README.md chefignore metadata.json templates/ $ cat cookbooks/nginx/README.md | head -n 20 Description =========== Installs nginx from package OR source code and sets up configuration handling similar to Debian's Apache2 scripts. (略) $
3. Templateの作成
では、chef-soloをProvisinerとして実行するためのPackerのTemplateを以下のように作成します。今回は、Amazon Linux 2013.03 64bit公式AMI(ami-39b23d38)を使用します。
packer.json
{
"builders": [{
"type": "amazon-ebs",
"access_key": "XXXXXXXXXXXXXXXX",
"secret_key": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
"region": "ap-northeast-1",
"source_ami": "ami-39b23d38",
"instance_type": "t1.micro",
"ssh_username": "ec2-user",
"ssh_timeout": "5m",
"ami_name": "packer-example {{timestamp}}"
}],
"provisioners": [{
"type": "chef-solo",
"cookbooks_paths": ["./cookbooks"],
"recipes": ["nginx"],
"json": {},
"prevent_sudo": false,
"skip_install": false
}]
}
以下補足です。
- 11行目の{{timestamp}}は、前回の記事で{{.CreateTime}}と記述していた箇所です。書き方が変わりました。
- 14行目のtypeアトリビュートにchef-soloと記述し、chef-soloの設定を続けていきます。まだドキュメント化されていない部分なので、なんとなく読み取ってください(苦笑)。
4. Packerの実行
Templateができたら、いよいよPackerを実行します。EC2インスタンスの作成ログからchef-soloの実行結果、AMIの作成ログまで順に出力されていきます。
$ packer build packer.json

--> amazon-ebs: AMIs were created:
ap-northeast-1: ami-XXXXXXXX
作成されたAMIを元にEC2インスタンスを起動し、SSHで接続してみます。
$ ssh ec2-user@ec2-XX-XX-XX-XX.ap-northeast-1.compute.amazonaws.com [ec2-user@ip-XX-XX-XX-XX ~]$ rpm -q nginx nginx-1.2.9-1.11.amzn1.x86_64 [ec2-user@ip-XX-XX-XX-XX ~]$ rpm -q chef chef-11.6.0-1.el6.x86_64 [ec2-user@ip-XX-XX-XX-XX ~]$
nginxとchefがちゃんとインストールされていますね!!
まとめ
というわけで、Packerで簡単にChefのインストール&実行したAMIを作成できることをご紹介しました。
Packerの開発は相変わらず非常に活発で、chroot環境のEC2で並列実行するBuilderというユニークな仕組みも追加されています。こちらも試して、またブログで紹介したいです。
皆さんもPackerを活用して楽にAMIを管理しましょう!!
