amazon-web-services - CloudFormation 中的条件 Dynamo 全局表

Question

我试图弄清楚如何在条件成立的情况下拥有全局 Dynamo 表，否则拥有常规 Dynamo 表。然而，linter 提示其有效性:预期有一个 block ，但在属性处得到了...。这是我的代码:

Resources:
    ClientNameTable:
      !If
        - SingleEnv
        - Type: AWS::DynamoDB::GlobalTable
        - Type: AWS::DynamoDB:Table

      Properties:
        TableName: ClientNameTest
        AttributeDefinitions:
          - AttributeName: uuuuu
            AttributeType: S
          - AttributeName: xxxxx
            AttributeType: S
        BillingMode: PAY_PER_REQUEST
        KeySchema:
          - AttributeName: uuuuu
            KeyType: HASH
          - AttributeName: xxxxx
            KeyType: RANGE
        StreamSpecification:
          StreamViewType: NEW_IMAGE
        TimeToLiveSpecification:
            AttributeName: time_to_live
            Enabled: true
        Replicas:
          !If
            - SingleEnv
              - Region: us-east-1
              - Region: us-west-2
            - !Ref "AWS::NoValue"

你不能这样写 If 。相反，您必须拥有两个独立的资源。

Resources:
    ClientNameTable:
      Condition: SingleEnv  
      Properties:
        TableName: ClientNameTest
        AttributeDefinitions:
          - AttributeName: uuuuu
            AttributeType: S
          - AttributeName: xxxxx
            AttributeType: S
        BillingMode: PAY_PER_REQUEST
        KeySchema:
          - AttributeName: uuuuu
            KeyType: HASH
          - AttributeName: xxxxx
            KeyType: RANGE
        StreamSpecification:
          StreamViewType: NEW_IMAGE
        TimeToLiveSpecification:
            AttributeName: time_to_live
            Enabled: true
        Replicas:
          !If
            - SingleEnv
              - Region: us-east-1
              - Region: us-west-2
            - !Ref "AWS::NoValue"
            
            
    ClientNameTable:
      Condition: NotSingleEnv  
      Properties:
        TableName: ClientNameTest
        AttributeDefinitions:
          - AttributeName: uuuuu
            AttributeType: S
          - AttributeName: xxxxx
            AttributeType: S
        BillingMode: PAY_PER_REQUEST
        KeySchema:
          - AttributeName: uuuuu
            KeyType: HASH
          - AttributeName: xxxxx
            KeyType: RANGE
        StreamSpecification:
          StreamViewType: NEW_IMAGE
        TimeToLiveSpecification:
            AttributeName: time_to_live
            Enabled: true
        Replicas:
          !If
            - SingleEnv
              - Region: us-east-1
              - Region: us-west-2
            - !Ref "AWS::NoValue"            

您必须在Conditions中创建NotSingleEnv。
