调用 ModifyInstanceSpec 修改指定实例的规格。

使用说明

如果您发现实例规格不能满足或者超出应用需求时，可以先参考支持变更的实例规格，查看实例支持的变配情况，然后再更改实例规格（包括vCPU和内存），支持升配和降配。

更改实例规格的注意事项和使用限制，请参见更改实例规格。

请求参数

下方仅列出该接口特有的请求参数和部分公共参数。更多信息请见公共参数。

Action string 必选示例值：ModifyInstanceSpec

要执行的操作，取值：ModifyInstanceSpec。

Version string 必选示例值：2020-04-01

API的版本，取值：2020-04-01。

ClientToken string 可选示例值：333456899ff****

保证请求幂等性。由客户端自动生成一个参数值，确保不同请求间该参数值唯一，避免当调用API超时或服务器内部错误时，客户端多次重试导致重复性操作。

取值：仅支持ASCII字符，且不能超过64个字符。

DryRun boolean 可选示例值：false

是否只预检此次请求。取值：

true：发送检查请求，不会修改实例规格。检查项包括是否填写了必需参数、请求格式、业务限制和ECS库存。如果检查不通过，则返回对应错误。如果检查通过，则返回错误码DryRunOperation。

false（默认）：发送正常请求，通过检查后直接修改实例规格。

InstanceId string 必选示例值：i-3thhlu8byl4bwbha****

实例ID。

InstanceTypeId string 必选示例值：ecs.g2i.large

修改后实例的规格。

支持修改的实例规格族请参见修改实例规格。

返回参数

下方仅列出本接口特有的返回参数。更多信息请参见返回结构。

InstanceId string 示例值：i-ybo349sxoncm9t******

操作的实例ID。

OrderId string 示例值：Order7021038849342******

订单号。
