无法在同一 cloudformation 堆栈中创建带有死信队列的 FIFO 队列

Question

我有一个包含 FIFO 队列及其关联的死信队列的 cloudformation 堆栈。以前这不是一个 FIFO 队列，并且部署得很好，首先建立了死信队列依赖关系，然后是“源队列”。切换到 FIFO 后就不再起作用了。我收到此错误：

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

所以看起来死信队列不再是首先创建的。

 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

事实证明，死信队列必须与其源具有相同的类型。

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'
