我有以下 Cloudformation 配置，它执行以下操作：

  • 创建和 Elasticbeanstalk 应用程序
  • 将域名链接到其负载均衡器

我需要能够访问 FTP 服务器，但它们只允许列入白名单的 IP 地址。

如果我多次运行此 Cloudformation，我将如何在配置中创建静态（弹性？）IP，通过它路由流量，并让 IP 保持不变？

通过 CloudFormation 使用弹性 IP 资源关联。

创建弹性 IP 资源：

Type: "AWS::EC2::EIP"
Properties:
   InstanceId: String
   Domain: String

将弹性 IP 资源与您的 EC2 实例资源相关联：

Type: "AWS::EC2::EIPAssociation"
Properties:
  AllocationId: String
  EIP: String
  InstanceId: String
  NetworkInterfaceId: String
  PrivateIpAddress: String

不要忘记加入这两个使用!Ref ，最后，这里有一个关于如何做到这一点的官方示例。 使用 AWS::EC2::EIP Snippet 分配 Amazon EC2 弹性 IP
