amazon-ec2 - 使用路由 53 创建 RDS cloudformation

Question

我在 AWS 云形成方面遇到问题。我需要创建 cloudformation，它将使用 RHEL 安装和配置 RDS，并使用路由 53 和主用户配置 mariadb。我首先从基本的 config.yaml 开始，但我遇到了 vpc 错误，它说

No default VPC for this user (Service: AmazonEC2; Status Code: 400; Error Code: VPCIdNotSpecified; Request ID: 407bd74c-9b85-4cce-b5a7-b816fe7aea15)

我的config.yaml是这样的

Resources:
   Ec2Instance1:
      Type: 'AWS::EC2::Instance'
      Properties:
           SecurityGroups:
               - !Ref InstanceSecurityGroup
           KeyName: adivir
           ImageId: ami-07dfba995513840b5
           AvailabilityZone: eu-central-1
           InstanceType: t2.micro
           UserData:
              Fn::Base64: !Sub |
               #!/bin/bash -xe
               yum install -y httpd
               yum install -y git
               yum install -y php php-mysql
               git clone https://github.com/demoglot/php.git /var/www/html
               systemctl restart httpd
               systemctl enable httpd
   Ec2Instance2:
      Type: 'AWS::EC2::Instance'
      Properties:

               #!/bin/bash -xe
               yum install -y httpd
               yum install git -y
               git clone https://github.com/demoglot/php.git /var/www/html
               systemctl restart httpd
               systemctl enable httpd
   InstanceSecurityGroup:
    Type: 'AWS::EC2::SecurityGroup'
    Properties:

    Properties:

          DBSecurityGroupIngress:
            - CIDRIP: 0.0.0.0/0
   MyDB:
    Type: 'AWS::RDS::DBInstance'
    Properties:
        DBName: kk

        DBSecurityGroups:
            - !Ref DBSECURITYGROUP
        Tags:
           - Key: name
             Value: kk
    DeletionPolicy: Snapshot

我需要做什么才能解决 vpc 错误并成功创建 RDS，以及如何以及在何处在 yaml 文件中添加路由 53 创建？数据库也需要连接到其他实例上的java应用程序。我需要与制作应用程序的人分享什么才能让他连接到数据库？另外，是否可以有一个 shell 脚本来按顺序运行 cloudformations，创建堆栈然后退出，这样就不需要每个团队成员都需要运行自己的云编队了？谢谢

此问题的解决方案及其发生原因已在最近的 AWS 博客中记录和解释:

• How do I resolve the CloudFormer error “No default VPC found for this user” in AWS CloudFormation?

基本上，解决方案是创建新的默认 vpc。

我也同意@mokugo-devops。您提出了太多的子问题，这限制了您报告的主要问题和问题的焦点和准确性。
