计算预占IP数

功能介绍

计算以下几种场景的预占用IP数量:

  • 计算创建LB所需IP数量:

    传入字段availability_zone_id,及可选字段l7_flavor_id、ip_target_enable、ip_version,不能传loadbalancer_id。

  • 计算创建LB的第一个七层监听器后新增占用IP数量:

    传入loadbalancer_id,其他字段不传。

  • 计算LB变更(规格变更或特性开启)新增占用IP数量:

    传入字段loadbalancer_id,及l7_flavor_id不为空或ip_target_enable为true。可以同时传入多个字段,表示同时进行多种变更所需要新增的占用IP数量。

  • 计算共享型ELB升级为独享型ELB所需占用IP数量:

    传入sence、loadbalancer_id,其他字段不传。

  • 计算ELB实例开启NAT64特性所需占用IP数量:

    传入nat64_enable、loadbalancer_id,其他字段不传。

说明:

  • 计算出来的预占IP数大于等于最终实际占用的IP数。

  • 新增占用IP数量,不包含已占用的IP数。

调用方法

请参见如何调用API

URI

GET /v3/{project_id}/elb/preoccupy-ip-num

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

所属项目id。

表2 Query参数

参数

是否必选

参数类型

描述

l7_flavor_id

String

负载均衡器七层规格的ID。传入该字段表示计算创建该规格的LB的预占IP数量,或变更LB的原七层规格到该规格所需要的新增预占IP数量。

适用场景:创建负LB,变更LB规格。

ip_target_enable

Boolean

跨VPC后端转发开关。

取值true表示计算创建开启跨VPC后端转发的LB的预占IP数量,或开启LB跨VPC后端转发所需要的新增预占IP数量。

取值false表示计算创建不开启跨VPC后端转发的LB的预占IP。

不传等价false。

适用场景:创建LB,LB开启跨VPC后端转发。

ip_version

Integer

负载均衡器IP地址类型,取值4,6 。

取值4表示计算创建支持IPv4地址的LB的预占IP。

取值6表示计算创建支持IPv6地址的LB的预占IP。

适用场景:创建LB。

loadbalancer_id

String

负载均衡器ID。计算LB变更或创建LB中的第一个七层监听器的新增预占IP。

适用场景:变更LB规格,开启跨VPC后端转发,开启/不开启地址族转换功能,创建LB中的第一个七层监听器。

availability_zone_id

Array of strings

计算创建AZ列表为availability_zone_id的负载均衡器实例的预占IP。

适用场景:创建LB。

使用说明:传入loadbalancer_id时,该参数无效。

scene

String

参数解释:计算共享型升级为独享型ELB负载均衡器实例的所需预占IP。

约束限制:必须同时传入loadbalancer_id。

取值范围:UPGRADE - 共享型升级为独享型ELB场景。

nat64_enable

Boolean

参数解释:

开启地址族转换。传入该字段表示计算创建LB及该LB下开启/不开启地址族转换特性的监听器所需要的预占IP,或者指定LB创建开启/不开启地址族转换特性的监听器所需要的新增预占IP。

取值范围:

true:开启地址族转换特性。

false:不开启地址族转换特性。

默认取值:

false
