AWS Autoscaled EC2 instance failing to launch with cloudformation
问题
我正在尝试从CloudFormation启动自动扩展的EC2实例，以下是我的CloudFormation模板。我收到了以下错误：
> 收到 0 个成功信号中的 1 个。无法满足 100% MinSuccessfulInstancesPercent 要求。
一旦出现这个错误，堆栈就会回滚并删除所有资源。

自动扩展组（ASG）已配置为要求成功信号。这个错误意味着ASG启动的实例在超时之前（因为这是初始堆栈创建时的5分钟）没有将这些消息发送回CFN。
尝试增加超时时间。还请确保实例具有互联网访问权限，以便能够发送信号。
<details>
<summary>英文:</summary>
The ASG is configured to require success signals. This error means that the instances the ASG launched didn't send those messages back to CFN before the timeout (5 minutes since this was the initial stack creation)
Try increasing the timeout. Also make sure the instances have internet access to be able to send the signal out
