实例扩容

功能介绍

实例规格变更。当前通过调用API,只支持按需实例进行实例扩容。

调用方法

请参见如何调用API

URI

POST /v2/{engine}/{project_id}/instances/{instance_id}/extend

表1 路径参数

参数

是否必选

参数类型

描述

engine

String

消息引擎。

project_id

String

项目ID,获取方式请参见获取项目ID

instance_id

String

实例ID。

请求参数

表2 请求Body参数

参数

是否必选

参数类型

描述

oper_type

String

变更类型。

取值范围:

  • storage:存储空间扩容,代理数量不变。

  • horizontal:代理数量扩容,每个broker的存储空间不变。

  • vertical:垂直扩容,broker的底层虚机规格变更,代理数量和存储空间不变。

new_storage_space

Integer

扩容后的存储空间。

当oper_type类型是storage或horizontal时,该参数有效且必填。

实例存储空间 = 代理数量 * 每个broker的存储空间。

当oper_type类型是storage时,代理数量不变,每个broker存储空间最少扩容100GB。

当oper_type类型是horizontal时,每个broker的存储空间不变。

new_broker_num

Integer

当oper_type参数为horizontal时,该参数有效。

取值范围:最多支持30个broker。

new_product_id

String

垂直扩容时的新产品ID。

当oper_type类型是vertical时,该参数才有效且必填。

产品ID可以从查询产品规格列表获取。

publicip_id

String

实例绑定的弹性IP地址的ID。

以英文逗号隔开多个弹性IP地址的ID。

当oper_type类型是horizontal时,该参数必填。

tenant_ips

Array of strings

指定的内网IP地址,仅支持指定IPv4。

指定的IP数量只能小于等于新增节点数量。

当指定IP小于节点数量时,未指定的节点随机分配内网IP地址。

second_tenant_subnet_id

String

实例扩容时新节点使用备用子网的id。

当实例扩容使用备用子网,则传入此值。

需要联系客服添加白名单才能传入此值。

响应参数

状态码: 200

表3 响应Body参数

参数

参数类型

描述

job_id

String

规格变更任务ID。

请求示例

  • 扩容存储空间(按需实例)。

    POST https://{endpoint}/v2/{engine}/{project_id}/instances/{instance_id}/extend
    
    {
      "oper_type" : "storage",
      "new_storage_space" : 600
    }
  • 扩容代理数量(按需实例)。

    POST https://{endpoint}/v2/{engine}/{project_id}/instances/{instance_id}/extend
    
    {
      "oper_type" : "horizontal",
      "new_storage_space" : 1600,
      "new_broker_num" : 4,
      "tenant_ips" : [ "127.xx.xx.x", "127.xx.xx.x", "127.xx.xx.x" ]
    }
  • 扩容代理规格(按需实例)。

    POST https://{endpoint}/v2/{engine}/{project_id}/instances/{instance_id}/extend
    
    {
      "oper_type" : "vertical",
      "new_product_id" : "c6.4u8g.cluster"
    }

响应示例

状态码: 200

实例扩容成功。

{
  "job_id" : "93b94287-728d-4bb1-a158-cb66cb0854e7"
}
