新规格实例的规格变更

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规格变更。

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
project_id	是	String	项目ID，获取方式请参见获取项目ID。
instance_id	是	String	实例ID。
engine	是	String	消息引擎的类型。支持的类型为rabbitmq。缺省值：rabbitmq

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	是	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	否	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_product_id	否	String	规格，例如c6.8u16g.cluster，当oper_type类型是vertical时，该参数才有效且必填。
new_broker_num	否	Integer	当oper_type参数为horizontal时，该参数有效。
new_spec_code	否	String	老规格，例如dms.instance.rabbitmq.cluster.c3.8u16g，当oper_type类型horizontal时，为dms.instance.rabbitmq.cluster.c3.8u16g.5，最后的数字5为代理数

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（老规格按需实例）。new_spec_code的值为原规格参数。

POST https://{endpoint}/{engine}/v2/{project_id}/instances/{instance_id}/extend

{
  "new_storage_space" : 600,
  "oper_type" : "storage",
  "new_spec_code" : "dms.instance.rabbitmq.cluster.c3.2u4g.3"
}

扩容代理数量（老规格按需实例）。new_storage_space填原存储大小，new_spec_code的值dms.instance.rabbitmq.cluster.c3.2u4g.5，最后数字5为代理个数。

POST https://{endpoint}/{engine}/v2/{project_id}/instances/{instance_id}/extend

{
  "new_storage_space" : 600,
  "oper_type" : "horizontal",
  "new_spec_code" : "dms.instance.rabbitmq.cluster.c3.2u4g.5"
}

扩容代理规格（老规格按需实例）。new_spec_code需要改成对应规格，例如2u4g改成4u8g。

POST https://{endpoint}/{engine}/v2/{project_id}/instances/{instance_id}/extend

{
  "new_storage_space" : 600,
  "oper_type" : "vertical",
  "new_spec_code" : "dms.instance.rabbitmq.cluster.c3.2u4g.5"
}

扩容存储空间（按需实例）。

POST https://{endpoint}/{engine}/v2/{project_id}/instances/{instance_id}/extend

{
  "new_storage_space" : 600,
  "oper_type" : "storage"
}

扩容代理数量（按需实例）。

POST https://{endpoint}/{engine}/v2/{project_id}/instances/{instance_id}/extend

{
  "oper_type" : "horizontal",
  "new_storage_space" : 500,
  "new_broker_num" : 5
}

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

实例规格变更成功。

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