扩容集群

功能介绍

该接口用于集群扩容实例(仅支持扩容elasticsearch实例)。只扩容普通节点,且只针对要扩容的集群实例不存在特殊节点(Master、Client、冷数据节点)的情况。集群扩容实例的数量和存储容量,请参考扩容实例的数量和存储容量

调用方法

请参见如何调用API

URI

POST /v1.0/{project_id}/clusters/{cluster_id}/extend

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID。获取方法请参见获取项目ID和名称

cluster_id

String

指定待扩容的集群ID。

请求参数

表2 请求Body参数

参数

是否必选

参数类型

描述

grow

ExtendClusterGrowReq object

集群扩容请求详细描述。

isAutoPay

Integer

是否自动支付。下单订购后,是否自动从客户的华为云账户中支付,而不需要客户手动去进行支付。该参数适用于包周期集群。

  • 1:是(会自动选择折扣和优惠券进行优惠,然后自动从客户华为云账户中支付),自动支付失败后会生成订单成功(该订单应付金额是优惠后金额)、但订单状态为“待支付”,等待客户手动支付(手动支付时,客户还可以修改系统自动选择的折扣和优惠券)。

  • 0:否(需要客户手动去支付,客户可以选择折扣和优惠券)。默认值为“0”。

表3 ExtendClusterGrowReq

参数

是否必选

参数类型

描述

modifySize

Integer

扩容实例个数。

集群已有实例个数和扩容实例个数总和不能超过32。

响应参数

请求示例

修改当前集群的实例个数。

POST /v1.0/6204a5bd270343b5885144cf9c8c158d/clusters/4f3deec3-efa8-4598-bf91-560aad1377a3/extend

{
  "grow" : {
    "modifySize" : 4
  },
  "isAutoPay" : 1
}
