Question

我正在使用terraform在下面创建一个AWS报警

resource "aws_cloudwatch_metric_alarm" "terraform-product-monitoring-dynamoDB-UserErrors" {
  alarm_name                = "terraform-product-monitoring-dynamoDB-UserErrors"
  comparison_operator       = "GreaterThanOrEqualToThreshold"
  evaluation_periods        = "2"
  metric_name               = "UserErrors"
  namespace                 = "AWS/DynamoDB"
  period                    = "120"
  statistic                 = "Sum"
  threshold                 = "1"
  alarm_description         = "This metric monitors the UserErrors for DynamoDB"
  alarm_actions             = ["${module.admin_sns_email_topic.arn}"]
  insufficient_data_actions = []
}

我想得到报警的arn，但是

"${aws_cloudwatch_metric_alarm.terraform-product-monitoring-dynamoDB-UserErrors.arn}"

给出错误

Resource 'aws_cloudwatch_metric_alarm.terraform-product-monitoring-dynamoDB-UserErrors' does not have attribute 'arn' for variable 'aws_cloudwatch_metric_alarm.terraform-product-monitoring-dynamoDB-UserErrors.arn'

有什么想法吗？

干杯

并非所有资源都有ARN。如果您需要获取资源aws_cloudwatch_metric_alarm的名称，请使用id

参考：

https://www.terraform.io/docs/providers/aws/r/cloudwatch_metric_alarm.html#id

如何在Terraform中获取AWS警报的ARN值
