AWS CloudFormation：默认 VPC“vpc”中不存在安全组“sg-”

问题描述

我有这个模板代码，我正试图在我的 ElasticBeanStalk 应用程序中实现它，但它引用了我的默认 vpc，我找不到如何引用我自己的 VPC 而不是默认 VPC。 这是我的YAML 代码：（我只需要知道如何引用我的 VpcID）

我尝试添加我在 aws 资源中找到的一些行，但它们不起作用：（每个单独的我没有一起使用它们）

Type: 'AWS::EC2::VPC::Id'

VpcId: String

       Vpc:
        Default: "vpc-"
        Type: String
      VpcCidr:
       Default: "10.0.0.0/16"
        Type: String

这是我的原始代码：

  MyCacheSecurityGroup:
    Type: 'AWS::EC2::SecurityGroup'
    Properties:
      GroupDescription: "Lock cache down to webserver access only"

解决方法

您必须使用 VpcId 属性将您的安全组放在您的 VPC 中：

  MyCacheSecurityGroup:
    Type: 'AWS::EC2::SecurityGroup'
    Properties:
      GroupDescription: "Lock cache down to webserver access only"
      VpcId: !Ref VpcId
      SecurityGroupIngress:
        - IpProtocol: tcp
          FromPort:
            Fn::GetOptionSetting:
              OptionName: CachePort
              DefaultValue: 11211
          ToPort:
            Fn::GetOptionSetting:
              OptionName: CachePort
              DefaultValue: 11211
          SourceSecurityGroupName:
            Ref: AWSEBSecurityGroup

我只是重写了整件事，在一个文件中使用这个：

Resources:
  MyElastiCache:
    Type: "AWS::ElastiCache::CacheCluster"
    Properties:
      CacheNodeType:
        Fn::GetOptionSetting:
          OptionName : "CacheNodeType"
          DefaultValue : "cache.t2.micro"
      NumCacheNodes:
        Fn::GetOptionSetting:
          OptionName : "NumCacheNodes"
          DefaultValue : "1"
      Engine:
        Fn::GetOptionSetting:
          OptionName : "Engine"
          DefaultValue : "memcached"
      CacheSubnetGroupName:
        Ref: "MyCacheSubnets"
      VpcSecurityGroupIds:
        - Ref: "MemcachedSecurityGroup"
  MemcachedSecurityGroup:
    Type: "AWS::EC2::SecurityGroup"
    Properties:
      GroupDescription: "Lock cache down to webserver access only"
      VpcId:
        Fn::GetOptionSetting:
          OptionName : "VpcId"
      SecurityGroupIngress :
        - IpProtocol : "tcp"
          FromPort :
            Fn::GetOptionSetting:
              OptionName : "CachePort"
              DefaultValue: "11211"
          ToPort :
            Fn::GetOptionSetting:
              OptionName : "CachePort"
              DefaultValue: "11211"
          SourceSecurityGroupId:
            Ref: "AWSEBSecurityGroup"
  MyCacheSubnets:
    Type: "AWS::ElastiCache::SubnetGroup"
    Properties:
      Description: "Subnets for ElastiCache"
      SubnetIds:
        Fn::GetOptionSetting:
          OptionName : "CacheSubnets"
Outputs:
  ElastiCache:
    Description : "ID of ElastiCache Cache Cluster with Memcached"
    Value :
      Ref : "MyElastiCache"

在另一个 .config 文件中使用这个：

option_settings:
  "aws:elasticbeanstalk:customoption":
    CacheNodeType : cache.t2.micro
    NumCacheNodes : 1
    Engine : memcached
    CachePort : 11211
    CacheSubnets:
      - subnet-
      - subnet-
      - subnet-
    VpcId: vpc-
