chef 概念 / y用語

Chef server: Chefサーバーでは送られてきたcookbookを元に、複数あるnodeサーバーに対して一気に指示を送り、cookbook通りの構成が瞬時に整う
Node
Workstation:「インフラの構成をこうしたい」というコードが書かれた「cookbook」を用意

chef-repo > site-cookbooks > hello > recipes > default.rb

template "index.html" do 
	path "/var/www/html/index.html"
	source "index.html.erb"
	mode 0644
end

chef-repo > site-cookbooks > hello > templates > default > index.html.erb

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>Document</title>
</head>
<body>
	hello
</body>
</html>

mysys-opensshとmsys-rsyncをインストールし、windowsの環境変数に、C:\MinGW\bin;C:\MinGW\msys\1.0\binを追加。C:\MinGW\msys\1.0\etc\fstabにc: /cygdrive/cを追加して、再度\chef\chef-repo> knife solo cook 192.168.33.10 –ssh-user vagrantを実行。

Chefはインフラをコードで記述する技術で、workstationからchef serverにcookbookを送って、nodeの管理を行います。
Chef

workstationにchefのインストール

gem install chef
gem install knife-solo

knife-configureで設定していきます。

knife configure

1. Chefのリポジトリ(cookbook)を作成…workstation
2. Nodeをchefに対応する
3. cookbookを作る
4. cookbookをnodeに反映

リポジトリ作成

> knife solo init chef-repo
> cd chef-repo

nodeをchef対応にする

> knife solo prepare 192.168.33.10 --ssh-user vagrant
Bootstrapping Chef...
vagrant@192.168.33.10's password:
Thank you for installing Chef!
Generating node config 'nodes/192.168.33.10.json'...

workstationよりcookbookの作成

\chef-repo> knife cookbook create hello -o site-cookbooks

chef-repo > site-cookbooks > hello > recipes > default.rb
