Getting Started

This section describes how to make API calls to create a private image from an ECS.

For details about how to call APIs, see Calling APIs.

  • Before using an ECS to create a private image, ensure that the ECS is stopped.
  • The token obtained from IAM is valid for only 24 hours. If you want to use a token for authentication, you can cache it to avoid frequently calling the IAM API.

Involved APIs

If you use a token for authentication, you must obtain the token and add X-Auth-Token to the request header of the IMS API when making an API call.

  • IAM API used to obtain the token
  • IMS API used to create a private image

Procedure

  1. Obtain the token by referring to Authentication.
  2. Send POST https://IMS endpoint/v2/cloudimages/action.
  3. Add X-Auth-Token to the request header.
  4. Specify the following parameters in the request body:

    {
    "name": "ims_test",  //Image name (a mandatory string)
    "description": "Image creation from an ECS",  //Image description (an optional string)
    "instance_id": "877a2cda-ba63-4e1e-b95f-e67e48b6129a",  //ECS ID (a mandatory string)
    "tags": [  
             "aaa.111",  
             "bbb.333",  
             "ccc.444"  
    ]  //Image tag list (optional, List<String>)
}

    If the request is successful, a job ID is returned.

    If the request fails, an error code and error information are returned. For details, see Error Codes.

  1. Query job details using the job ID by referring to Querying the Status of an Asynchronous Job.

    If the job status is SUCCESS, the private image is successfully created.

    For details about status codes for request exceptions, see Status Codes.

  2. Obtain the image ID from the body of the job and query, delete, and export the private image using the image ID.
