使用terraform创建Cloud watch警报并在警报命中时发送通知

Question

  

使用Terraform创建云观察警报但遇到错误   解析错误在1:20：预期“}”，但发现无效序列“$”，    如何在维度和范围内传递多个变量？ alarm_actions

variable "sfn_name"         { }
variable "sns_topic"        { }

resource "aws_cloudwatch_metric_alarm" "checkQueueLength" {
  alarm_name = "MonitorQueueLength"
  comparison_operator = "GreaterThanThreshold"
  evaluation_periods = "1"
  metric_name = "ExecutionsStarted"
  namespace = "AWS/States"
  period = "2"
  statistic = "Sum"
  threshold = "1"
  dimensions {
    StateMachineArn = "${aws_sfn_activity.${var.sfn_name}.arn}"
    alarm_description = "checkStatesQueueLength"
    actions_enabled = "true"
  }
  alarm_actions = ["${aws_sns_topic.${var.sns_topic}.arn}"]
}

Answer 1

你不会。相反，你会传入aws_sfn_activity和sns主题arn。

variable "sfn_arn"         { }
variable "sns_topic_arn"        { }

resource "aws_cloudwatch_metric_alarm" "checkQueueLength" {
  alarm_name = "MonitorQueueLength"
  comparison_operator = "GreaterThanThreshold"
  evaluation_periods = "1"
  metric_name = "ExecutionsStarted"
  namespace = "AWS/States"
  period = "2"
  statistic = "Sum"
  threshold = "1"
  dimensions {
    StateMachineArn = "${var.sfn_arn}"
    alarm_description = "checkStatesQueueLength"
    actions_enabled = "true"
  }
  alarm_actions = ["${var.sns_topic_arn}"]
}
