          TargetType: instance

          VpcId: !Ref vpc-******

收到错误模板无效:模板格式错误:未解析的资源依赖项 [子网-、sg-、子网- , vpc-*] 在模板的资源 block

请帮我添加

Answer 1

如果vpc-*****、subnet-******、sg-********* * 是您现有 VPC、子网和安全组的实际 ID，那么您不需要 !Ref 来引用它们。

只需提供它们，无需 !Ref，例如

SecurityGroups:
  - sg-**********
Subnets:
  - subnet-******
  - subnet-*******

VpcId: vpc-******

新模板版本:

AWSTemplateFormatVersion: 2010-09-09
Resources:
  MyLoadBalancer:
    Type: 'AWS::ElasticLoadBalancingV2::LoadBalancer'
    Properties:
      IpAddressType: ipv4
      Name: mytestingELB
      Scheme: internet-facing
      Type: application
      SecurityGroups:
        - !Ref sg-**********
      Subnets:
        - !Ref subnet-******
        - !Ref subnet-*******

  MyTargetGroup
      'AWS::ElasticLoadBalancingV2::TargetGroup':
        Properties:
          HealthCheckIntervalSeconds: '30'
          HealthCheckPath: /
          HealthCheckProtocol: HTTP
          HealthCheckTimeoutSeconds: '5'
          HealthyThresholdCount: '5'
          Matcher:
            HttpCode: '200'
          Name: testingtargetgroup
          Port: '80'
          Protocol: HTTP
          TargetType: instance
          UnhealthyThresholdCount: '2'
          VpcId: !Ref vpc-******

添加了

MyTargetGroup 并删除了 AvailabilityZones 和 Metadata。
