我有一个创建EC2实例的CF模板，我正在元数据中进行一些引导以安装httpd并在/var/www/html/index.html中创建一个简单的index.html并启动httpd。 / p>
我还配置了cfn-hup helper，以便在更新堆栈时再次运行并执行UserData。创建堆栈后，我通过更改index.html文件中的内容来更新了堆栈，我等待了15分钟以上才能看到更改。但是似乎cfn-hup没有执行更改。这是我的模板，不确定我错过了什么。

答案 0 :(得分：0)
不应该...
“ action = / opt / aws / bin / cfn-init -s”，{“ Ref”：“ AWS :: StackId”}，“ -r WebServerInstance”，
是
“ action = / opt / aws / bin / cfn-init -s”，{“ Ref”：“ AWS :: StackId”}，“ -r EC2Instance”，
答案 1 :(得分：0)
所以有两个错误，一个是specifying the wrong resource in /etc/cfn/hooks.d/cfn-auto-reloader.conf's action，另一个是missing the mode,owner and group properties for /etc/cfn/hooks.d/cfn-auto-reloader.conf
这是有效的cf模板
