S3 通知配置定义不明确？

Question

我正在尝试使用 Terraform 将两个 AWS lambda 函数连接到 S3 事件。

我的配置如下：

resource "aws_s3_bucket_notification" "collection_write" {
  bucket = aws_s3_bucket.fruit.id

  lambda_function {
    lambda_function_arn = aws_lambda_function.apple.arn
    events              = [ "s3:ObjectCreated:*" ]
    filter_prefix       = "foo/"
  }

  lambda_function {
    lambda_function_arn = aws_lambda_function.banana.arn
    events              = [ "s3:ObjectCreated:*" ]
    filter_prefix       = "foo/"
  }
}

但是 AWS / Terraform 不喜欢这样：

Error: Error putting S3 notification configuration: InvalidArgument: Configuration is ambiguously defined. Cannot have overlapping suffixes in two rules if the prefixes are overlapping for the same event type.
    status code: 400

我应该如何在 Terraform 中编写这个？

Answer 1

您的 terraform 没有错，只是 s3 仅限于单个事件通知。最好将 s3 事件发送到 SNS 主题，然后触发 lambda 以实现相同的功能。

Answer 2

您还可以通过 AWS SQS 实现触发多个 Lambda 函数。对于此类用例，AWS SQS 功能强大且易于使用消息队列。
