amazon-web-services - 如果 InstanceSecurityGroup 的 VPCID 为 String，如何导入堆栈

Question

MySecurityGroup: 
    Type: AWS::EC2::SecurityGroup
    Properties: 
      GroupDescription: Allow http to client host
      SecurityGroupIngress:
          - IpProtocol: tcp
            FromPort: 80
            ToPort: 80
            CidrIp: !Ref SSHLocation 
      SecurityGroupIngress:
          - IpProtocol: tcp
            FromPort: 443
            ToPort: 443
            CidrIp: !Ref SSHLocation
      SecurityGroupIngress:
          - IpProtocol: tcp
            FromPort: 22
            ToPort: 22
            CidrIp: !Ref SSHLocation
      VpcId: 
          - Fn::ImportValue: !Sub ${ExportVPCStack}-VPC 

我收到一条错误消息，指出实例安全组的 VPCId 为字符串。

我怎样才能避免出现错误？

Answer 1

由于 -，您正在将 VpcId 创建为列表。应该是:

      VpcId: 
         Fn::ImportValue: !Sub ${ExportVPCStack}-VPC
