Modifying the Specifications of an ECS (V1.1)

Function

This API is used to modify ECS specifications.

This API is an asynchronous API. After the specifications modification request is successfully delivered, a job ID is returned. This does not mean the modification is complete. You need to call the API by referring to Querying Task Execution Status to query the job status. The SUCCESS status indicates that the modification is successful.

Constraints

  • You can modify the ECS specifications only when the ECS is stopped.
  • The flavor (memory and vCPUs) after the modification cannot be lower than that before the modification.

URI

POST /v1.1/{project_id}/cloudservers/{server_id}/resize
