ALIYUN::VPC::EIPAssociation用于为云产品实例绑定弹性公网IP（EIP）。

语法

{
  "Type": "ALIYUN::VPC::EIPAssociation",
  "Properties": {
    "AllocationId": String,
    "InstanceId": String,
    "PrivateIpAddress": String,
    "Mode": String
  }
}

属性

属性名称 类型 必须 允许更新 描述 约束
AllocationId String 是 是 弹性公网IP的ID。 无
InstanceId String 是 是 云产品实例的ID。 支持以下云产品实例类型：
  • VPC类型的ECS实例。
  • VPC类型的SLB实例。
  • NAT网关。
  • 高可用虚拟IP（HaVip）。
  • 弹性网卡。
PrivateIpAddress String 否 是 交换机网段内的一个私网IP地址。 如果不指定该参数，系统将根据VPC ID和交换机ID自动分配一个私网IP地址。
Mode String 否 是 绑定模式。 取值：
  • NAT（默认值）：NAT模式（普通模式）。
  • MULTI_BINDED：多EIP网卡可见模式。
  • BINDED：EIP网卡可见模式。

返回值

Fn::GetAtt

  • EipAddress：弹性公网IP的地址。
  • AllocationId：弹性公网IP的ID。
