Cloudformation ValidationError：堆栈（堆栈名称）处于CREATE_COMPLETE状态，无法发出信号

Question

我创建了一个aws Cloudformation脚本，它启动了，但是当我查看日志时，它显示以下错误：

ValidationError：堆栈stackarn处于CREATE_COMPLETE状态，无法发出信号

我查看了有关此错误的其他帖子，这些帖子表明问题出在实例ID是从第一个实例或自动伸缩组派生的，而该ID没有设置所需的容量，这对我都不适用。

这是我的云形成模板

似乎您没有在等待自动伸缩组，因此在ASG具有任何工作实例之前，堆栈创建已完成。在实例启动并执行时cfn-signal，堆栈已完成。

尝试添加CreationPolicy：

https://aws.amazon.com/blogs/devops/use-a-creationpolicy-to-wait-for-on-instance-configurations/

和/或UpdatePolicy：

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-updatepolicy.html

根据您的情况的具体情况，如下所示：

"WebServerFleet": {
  "CreationPolicy": {
    "ResourceSignal": {
      "Timeout": "PT15M",
      "Count": "1"
    }
  },
  "UpdatePolicy": {
    "AutoScalingScheduledAction": {
      "IgnoreUnmodifiedGroupSizeProperties": "true"
    },
    "AutoScalingRollingUpdate": {
      "MinInstancesInService": "1",
      "MaxBatchSize": "2",
      "WaitOnResourceSignals": "true",
      "PauseTime": "PT15M"
    }
  }
}

如果您的设置更长或更短，则可能需要调整超时。批次大小也是要考虑的因素。
