今天豆子尝试着使用Cloudformation Designer来创建一个Template 文件。Designer对于初学者还是很有帮助的，一方面可以通过可视界面拖动Resource，另外可以按住Ctrl+Space 来提示对应的Property里面可以配置哪些东西。还可以直接拖动线条来实现依赖关系。当然最重要的一点是可以帮忙进行语法检测。
下面是一个小例子。
平常豆子需要经常创建S3的bucket进行备份，对于每个Bucket需要配置lifecycle rule，创建对应的user policy，attach到一个新的User，然后配置这个新用户的Secretkey，最后在客户端写个小脚本定期备份。
现在把AWS的这一部分都改成用Cloudformation实现。
基本的resource就这4个部分。双击rerouce可以进行编辑对应的内容，在空格处随便单击一下 就可以编辑Parameter等section
编辑过程中，可以从对应的Resource里面点开他的帮助文档，这个是一个很方便的功能
提交之前，记得检查语法。

}下面是stack创建的过程，因为我设置了依赖关系，所以顺序是S3 Bucket, User, UserPolicy和UserKey
最后输出我的AccessID和SecretKey，这样我在客户端才能调用
