[Terraform] Cloudwatch Alarmを特定リージョンに作成しようとして失敗した件

この記事について

以下のようなTerraformコードを作成して、CloudWatch Alarmをバージニアリージョンに作成しようとした。

resource "aws_cloudwatch_metric_alarm" "for_topic" {
  provider            = aws.virginia

  alarm_name          = local.alert.name
  comparison_operator = "LessThanThreshold"
  evaluation_periods  = "1"
  metric_name         = "HealthCheckStatus"
  namespace           = "AWS/Route53"
  period              = "60"
  statistic           = "Minimum"
  threshold           = "1"
  alarm_actions       = [aws_sns_topic.topic_route53.arn]

  dimensions = {
    HealthCheckId     = aws_route53_health_check.hoge.id
  }

  depends_on          = [aws_route53_health_check.hoge]
}

resource "aws_sns_topic" "topic_route53" {

  name = local.sns.topic_name
  tags = {
    Name = local.sns.topic_name
  }
}

resource "aws_sns_topic_subscription" "subscription_firehose" {
  topic_arn             = aws_sns_topic.topic_route53.arn
  protocol              = "firehose"
  endpoint              = aws_kinesis_firehose_delivery_stream.firehose_newrelic.arn
  subscription_role_arn = aws_iam_role.subscription-firehose.arn
}
