无法在同一 cloudformation 堆栈中使用死信队列创建 FIFO 队列

Question

我有一个 cloudformation 堆栈，其中包含一个 FIFO 队列及其关联的死信队列。以前这不是 FIFO 队列，它部署得很好，首先建立死信队列依赖，然后 "source queue"。改成FIFO后就不行了。我收到此错误：

"Template error: SQSQueue https://sqs.us-east-1.amazonaws.com/1234/dev-assignments-dlq doesn't exist",

看来死信队列不再先创建了。

 AWSTemplateFormatVersion: "2010-09-09"
    Resources:
      SourceQueue:
        Type: AWS::SQS::Queue
        Properties:
          FifoQueue: true
          QueueName: 'dev-push-notifications.fifo'
          RedrivePolicy:
            deadLetterTargetArn:
              Fn::GetAtt:
                - 'DeadLetterQueue'
                - 'Arn'
            maxReceiveCount: 5
          VisibilityTimeout: 30
      DeadLetterQueue:
        Type: AWS::SQS::Queue
        Properties:
          QueueName: 'dev-push-notifications-dlq'

Answer 1

这很奇怪，因为 Cloudformation 应该检测到 GetAtt 的依赖关系。您可以尝试使用 DependsOn 属性显式声明它：

AWSTemplateFormatVersion: "2010-09-09"
  Resources:
    SourceQueue:
      Type: AWS::SQS::Queue
      DependsOn: DeadLetterQueue
      Properties:
        # ...

Answer 2

事实证明，死信队列必须与其来源的类型相同。

将 cloudformation 堆栈更改为此有效：

AWSTemplateFormatVersion: "2010-09-09"
Resources:
  SourceQueue:
    Type: AWS::SQS::Queue
    Properties:
      FifoQueue: true
      QueueName: 'dev-push-notifications.fifo'
      RedrivePolicy:
        deadLetterTargetArn:
          Fn::GetAtt:
            - 'DeadLetterQueue'
            - 'Arn'
        maxReceiveCount: 5
      VisibilityTimeout: 30
  DeadLetterQueue:
    Type: AWS::SQS::Queue
    Properties:
      FifoQueue: true
      QueueName: 'dev-push-notifications-dlq.fifo'
