networking - 云形成: Referencing a NAT gateway from a route gives Invalid id: "nat-0ad5d1c106dd74175"

Question

我有以下 Cloud Formation 配置，其中包括子网、路由表/路由、nat 网关和弹性 IP:

  lambdaPointToIgwStaging:
    Type: 'AWS::EC2::Subnet'
    Properties:
      VpcId: !Ref mainVpc
      CidrBlock: '210.12.172.0/20'
      AvailabilityZone: eu-west-1b
  lambdaEipStaging:
    Type: 'AWS::EC2::EIP'
    Properties:
    Domain: 'vpc'
  lambdaNatGatewayStaging:
    Type: 'AWS::EC2::NatGateway'
    Properties:
      AllocationId: !GetAtt lambdaEipStaging.AllocationId
      SubnetId: !Ref lambdaPointToIgwStaging
  lambdaNatRoute:
    Type: 'AWS::EC2::Route'
    Properties:
      DestinationCidrBlock: '0.0.0.0/0'
      InstanceId: !Ref lambdaNatGatewayStaging
      RouteTableId: !Ref lambdaToNatStaging
    DependsOn: lambdaNatGatewayStaging
  lambdaToNatStaging:
    Type: 'AWS::EC2::RouteTable'
    Properties:
      VpcId: !Ref mainVpc

创建lambdaNatRoute时失败，并出现错误Invalid id: "nat-0ad5d1c106dd74175"，这是一个完全无用的错误。我尝试了各种dependsOn配置，但似乎都没有帮助。有什么想法吗？

Answer 1

最终通过了 AWS 支持，答案是在我的路由定义中使用 NatGatewayId 而不是 InstanceId:

  lambdaNatRoute:
   Type: 'AWS::EC2::Route'
   Properties:
     DestinationCidrBlock: '0.0.0.0/0'
     NatGatewayId: !Ref lambdaNatGatewayStaging
     RouteTableId: !Ref lambdaToNatStaging
