AWS CloudFormation堆栈失败，错误收到0 SUCCESS信号（1）

我的AWS CloudFormation模板失败并显示错误：

  

收到0个SUCCESS信号1.无法满足100％   MinSuccessfulInstancesPercent要求

AWS Coudformation stack events

我认为我的WaitConditionHandles设置不正确（或者EC2实例可能没有发送），但不知道如何解决这个问题。

所有内容（ASG，EC2实例）似乎都在AWS中正确创建。

我正在使用以下CloudFormation模板：

<强> TLDR

这是EC2无法向ASG发送成功信号时发生的一般性错误。可能出现这种情况的原因有很多种，但很可能无论您使用哪种健康检查都无法按预期工作。

使用下面的userData应该对运行状况检查进行硬编码，这是开始测试应用程序和Cloud Formation模板的好方法。

的所有引用

我的AWS::CloudFormation::WaitCondition脚本存在问题：

  • 脚本需要执行UserData个标记
  • 命令没有正确的参数
  • 未正确注入变量（例如<script>）

结果是：

${AWS::StackName}

您错过了IAM角色- cloudformation:SignalResource中的PolicyDocument操作。发送信号需要此权限。
