【问题描述】：

我有这个资源是由 terraform 创建的。如何在下一个资源创建中引用 arn？

resource \"aws_cloudformation_stack\" \"datadog_forwarder\" {
  name         = \"datadog-forwarder\"
  capabilities = [\"CAPABILITY_IAM\", \"CAPABILITY_NAMED_IAM\", \"CAPABILITY_AUTO_EXPAND\"]
  parameters = {
    DdApiKeySecretArn = \"secret_arn\",
    DdSite            = \"datadoghq.com\",
    FunctionName      = \"datadog-forwarder\"
    DdTags            = \"env:dev\"
  }
  template_url = \"https://datadog-cloudformation-template.s3.amazonaws.com/aws/forwarder/latest.yaml\"
}

我需要在这里引用它：

resource \"aws_cloudwatch_log_subscription_filter\" \"datadog_log_subscription_navblue-dd-agent\" {
  name            = \"datadog_log_subscription_filter\"
  log_group_name  = \"/\"
  destination_arn = ARN_GOES_HERE
  filter_pattern  = \"\"
}

【解决方案1】：

ID 是资源的 arn。用这个：

resource "aws_cloudwatch_log_subscription_filter" "datadog_log_subscription_navblue-dd-agent" {
  name            = "datadog_log_subscription_filter"
  log_group_name  = "/"
  destination_arn = aws_cloudformation_stack.datadog_forwarder.id
  filter_pattern  = ""
}
