模板格式错误：未解决的资源依赖关系[SUBNET-057BA3DF40F87DA4E]在模板的资源块中 我正在尝试使用CloudFormation在VPC中创建EC2实例，当我运行以下内容时： AWS CloudFormation create-create-stack - stack-name stack -region us-east-1-template-body file：//file.yml ...

Question

An error occurred (ValidationError) when calling the CreateStack operation:
Template format error: Unresolved resource dependencies [subnet-057ba3df40f87da4e] 
in the Resources block of the template

知道这是我用来创建此堆栈的文件：

Resources:

  accessSecurityGroup:
    Type: AWS::EC2::SecurityGroup
    Properties: 
      GroupDescription: "new EC2 security group for HTTP and SHH ports"
      SecurityGroupIngress: 
        - IpProtocol: tcp
          FromPort: 80
          ToPort: 80
          CidrIp: 0.0.0.0/0
      SecurityGroupEgress:
        - IpProtocol: -1
          FromPort: -1
          ToPort: -1
          CidrIp: 0.0.0.0/0
      VpcId: "vpc-09495a820716bff3b"
  
  EC2Instance:
    Type: AWS::EC2::Instance
    Properties:
      ImageId: "ami-0022f774911c1d690"
      InstanceType: t3.micro
      NetworkInterfaces: 
        - AssociatePublicIpAddress: "true"
          DeviceIndex: "0"
          GroupSet: 
            - Ref: "accessSecurityGroup"
          SubnetId: 
            Ref: "subnet-057ba3df40f87da4e"
      UserData:
        Fn::Base64: 
          !Sub |
            #!/bin/bash
            sudo yum update -y
            sudo yum install -y httpd
            sudo systemctl start httpd
            sudo systemctl enable httpd 
      SecurityGroupIds:
        - !Ref accessSecurityGroup

我对上述

VpcId

存在，我不确定问题是什么。

SubnetId

ref

The intrinsic function

滴

 returns the value of the specified parameter or resource.

由于它不是指参数或资源，并且该值是硬编码
