Querying the Target ECS Flavors to Which a Flavor Can Be Changed
Function
An ECS flavor cannot be changed to certain flavors. This API is used to query the target flavors to which a specified ECS flavor can be changed.
URI
GET /v1/{project_id}/cloudservers/resize_flavors?instance_uuid={instance_uuid}&source_flavor_id={source_flavor_id}&source_flavor_name={source_flavor_name}
Parameter |
Mandatory |
Description |
---|---|---|
project_id |
Yes |
Specifies the project ID. For details about how to obtain the ID, see Obtaining a Project ID. |
One of the instance_uuid, source_flavor_id, and source_flavor_name parameters must be configured. If multiple parameters are configured, the system processes the instance_uuid, source_flavor_id, and source_flavor_name parameters in descending order by default.
If instance_uuid is used to query the flavors that can be changed to, only the flavors supporting the image based on which the target ECS is created are returned. The reason is as follows: Images rely on flavors. If an ECS is created using a public image, the API filters the flavors supported by the image.
Table 2 describes the request parameters.
