推荐答案

如果您想在指定的stop UserGuide / aws-properties-cw-alarm.html rel = nofollow noreferrer> AWS :: CloudWatch :: Alarm 将资源转换为 ALARM 状态，您可以使用arn：aws：automate：region：ec2：stop ARN完成此操作 http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cw-alarm.html#cfn-cloudwatch-alarms-alarmaction rel = nofollow noreferrer> Al的AlarmActions 属性

If you want to change the EC2 instance state to stop when a specified AWS::CloudWatch::Alarm Resouce transitions into ALARM state, you can accomplish this using the special arn:aws:automate:region:ec2:stop ARN in the AlarmActions property for the alarm.

但是请注意，在此之前，您需要使用Amazon EC2或CloudWatch控制台手动创建至少一个停止，终止或重新启动警报，以创建警报。 EC2ActionsAccess IAM角色。创建此IAM角色后，您可以直接使用CloudFormation资源创建停止，终止或重新启动警报。请参阅 PutMetricAlarm 文档以获取更多详细信息。

Note however that before this will work, you need to manually create at least one stop, terminate, or reboot alarm using the Amazon EC2 or CloudWatch console to create the EC2ActionsAccess IAM role. After this IAM role is created, you can create stop, terminate, or reboot alarms using the CloudFormation resource directly. See the PutMetricAlarm documentation for more details.
