实例规格变更
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
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
engine |
是 |
String |
消息引擎的类型。支持的类型为rocketmq。 |
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。 |
请求参数
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
oper_type |
是 |
String |
变更类型 取值范围:
|
new_storage_space |
否 |
Integer |
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。
|
new_product_id |
否 |
String |
当oper_type类型是vertical时,该参数才有效且必填。 |
new_broker_num |
否 |
Integer |
代理数量 当oper_type参数为horizontal时,该参数必填。 |
publicip_id |
否 |
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参数为horizontal且开启了公网访问时,此参数必填。 |
