问题描述

使用以下 yaml 时出现错误.我已经检查了代码，但我认为没有任何问题.我的结构计划有一个具有 2 个公共子网和 2 个私有子网的 VPC.一个 Web 服务器实例将放置在公共子网 2 中.我认为问题可能与实例创建有关，因为在实例创建过程中出现错误.

I get error by using the following yaml. I have checked the code but I dont think there's any problem. My structure is planned to have a VPC with 2 public subnet and 2 private subnet. One web server instance will be placed in public subnet 2. I think the problem maybe related to instance creation, coz the error appear during the instance creation process.

推荐答案

SecurityGroups 仅适用于默认 VPC 或 EC2-classic:

SecurityGroups is only for default VPC or EC2-classic:

对于非默认 VPC，您必须改用安全组 ID.

For a nondefault VPC, you must use security group IDs instead.

因此最好使用 SecurityGroupIds.

      SecurityGroupIds:
        - !GetAtt WebServerSecurityGroup.GroupId

您的 WebServerSecurityGroup 也属于默认 VPC，但您的实例位于自定义 VPC 中.您需要 VpcId 用于您的安全组:

Also your WebServerSecurityGroup belongs to default VPC, but your instance is in a custom VPC. You need VpcId for your security group:

  WebServerSecurityGroup:
    Type: AWS::EC2::SecurityGroup
    Properties:
      GroupDescription: Enable HTTP access via port 80 and SSH access via port 22
      SecurityGroupIngress:
      - IpProtocol: tcp
        FromPort: '80'
        ToPort: '80'
        CidrIp: 0.0.0.0/0
      - IpProtocol: tcp
        FromPort: '22'
        ToPort: '22'
        CidrIp: !Ref SSHLocation
      VpcId: !Ref VPC

您的 cfn-signal 应该是(错误的 --resource):

Your cfn-signal should be (wrong --resource):

/opt/aws/bin/cfn-signal -e $? --stack ${AWS::StackId} --resource WebServerInstance --region ${AWS::Region}
