Cloudformation验证错误：堆栈（堆栈名称）处于CREATE_COMPLETE状态，无法发出信号。

aws-cloudformation
7

我已经创建了一个AWS CloudFormation脚本，它已经启动，但是当我查看日志时，显示以下错误：

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

我查看了其他帖子的内容，这些帖子提到此错误可能是由于实例ID来自第一个实例或自动缩放组没有设置所需容量，但这些都不适用于我。

这是我的CloudFormation模板：

注意：为了防止stackoverflow反馈文件过大，CF设计器代码已被排除在外。 有什么想法是什么原因导致了这个问题？
你正在使用的脚本中有什么内容？ - kichik
这是失败的脚本 "# Signal the status from cfn-init\n", "/opt/aws/bin/cfn-signal -e $? "," --stack ", { "Ref": "AWS::StackName" }, " --resource WebServerFleet ", " --region ", { "Ref": "AWS::Region" }, "\n" - SamBremner
如果您尝试多次发出信号，也可能会出现此错误。 - Levi

看起来你没有等待自动扩展组，因此堆栈创建在ASG有任何工作实例之前完成。当实例启动并执行时，堆栈已经完成。
尝试添加： https://aws.amazon.com/blogs/devops/use-a-creationpolicy-to-wait-for-on-instance-configurations/ 和/或： https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-updatepolicy.html 根据你的情况，尝试像下面这样的方式：
"WebServerFleet": {
  "CreationPolicy": {
    "ResourceSignal": {
      "Timeout": "PT15M",
      "Count": "1"
    }
  },
  "UpdatePolicy": {
    "AutoScalingScheduledAction": {
      "IgnoreUnmodifiedGroupSizeProperties": "true"
    },
    "AutoScalingRollingUpdate": {
      "MinInstancesInService": "1",
      "MaxBatchSize": "2",
      "WaitOnResourceSignals": "true",
      "PauseTime": "PT15M"
    }
  }
}

如果您的设置时间较长或较短，您可能需要调整超时时间。批处理大小也是需要考虑的因素。

这真是太好了，正是我所需要的。我还遇到另一个问题，我的负载均衡器在实例设置完成之前就开始ping它，因此无法获得200响应代码，并将其标记为不可用状态。有没有办法在ping实例之前等待它们准备好？ - SamBremner
错误也可能发生在您尝试多次发出信号的情况下。 - Levi

我遇到了同样的问题，CF堆栈已经达到了CREATE_COMPLETE状态，因此cfn-signal无法使用。将CreationPolicy附加到EC2资源上，告诉CloudFormation在5分钟内等待1个成功信号，然后继续堆栈创建并将其标记为CREATE_COMPLETE。因此，使用cfn-signal和CreationPolicy解决了该问题。以下是堆栈模板
