添加独立master、client

功能介绍

由于集群数据面业务的增长或者不确定性,很难在一开始就能够把集群的规模形态想明白,该接口能够在非独立master和client的集群上面添加独立master、client角色。

调用方法

请参见如何调用API

URI

POST /v1.0/{project_id}/clusters/{cluster_id}/type/{type}/independent

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

指定需要独立master或client的集群ID。

type

String

指定待新增独立节点类型。

  • ess-master:Master节点。

  • ess-client:Client节点。

请求参数

表2 请求Body参数

参数

是否必选

参数类型

描述

type

IndependentTypeReq object

独立master或client请求体参数。

is_auto_pay

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 IndependentTypeReq

参数

是否必选

参数类型

描述

flavor_ref

String

规格id,该参数通过获取实例规格列表接口获取,根据集群版本选择所需要的规格id

node_size

Integer

要独立节点个数。

  • 如果路径参数type取值为“ess-master”即新增独立master节点,节点个数必须为大于等于三且小于等于10的奇数。

  • 如果路径参数type取值为“ess-client”即新增独立client节点,节点个数要求大于等于1小于等于32。

volume_type

String

节点存储类型:取值为ULTRAHIGH,COMMON,HIGH。

响应参数

状态码: 200

表4 响应Body参数

参数

参数类型

描述

id

String

集群ID。

请求示例

添加独立master、client。

POST /v1.0/6204a5bd270343b5885144cf9c8c158d/clusters/ea244205-d641-45d9-9dcb-ab2236bcd07e/type/ess-client/independent

{
  "type" : {
    "flavor_ref" : "d9dc06ae-b9c4-4ef4-acd8-953ef4205e27",
    "node_size" : 3,
    "volume_type" : "COMMON"
  }
}

响应示例

状态码: 200

请求已成功。

{
  "id" : "320afa24-ff2a-4f44-8460-6ba95e512ad4"
}
