amazon-web-services - 如何从参数中指定 ELB 的子网列表？

Question

我正在尝试根据区域类型为 ELB 指定子网例如，这就是我的参数中的内容

PublicSubnetsEastRegion:
  Description: List of public subnets in us-west-2 region 
  Default: 'subnet-0bc21846adc3391fa,subnet-044a6f3e47331f209,subnet-0277131ad616e1b50'
  Type: 'List<String>'

这就是我在 ELB 中引用的方式

BastionELB:
    Type: AWS::ElasticLoadBalancing::LoadBalancer
    Properties: 

      ConnectionDrainingPolicy: 
        Enabled: !Ref ELBConfigConnectionDraining
        Timeout: !Ref ELBConfigConnectionDrainingTimeout

      SecurityGroups: 
        - !Ref BastionClientsdevELBIntuitSecurityGroup

      Subnets:
        - !If [ isRegionUS-WEST-2, !Ref PublicSubnetsWestRegion, !Ref PublicSubnetsEastRegion ]

但这不断抛出错误子网必须是列表类型。我如何根据条件(确定区域)在 ELB 中引用它们

Answer 1

您不需要-。应该是:

   Subnets:
      !If [ isRegionUS-WEST-2, !Ref PublicSubnetsWestRegion, !Ref PublicSubnetsEastRegion ]
