Creating a Migration Task

Scenarios

This section describes how to create a migration task by calling APIs. For details, see Calling APIs.

Involved APIs

• Obtaining a User Token Through Password Authentication: This API is used to obtain the user token for authentication.
• Creating a Migration Task: used to create a migration task using the source and destination AK/SK pairs
• Querying a Migration Task: used to query the task details based on the migration task ID to check whether the migration task has been created successfully

Prerequisites

• You have obtained the AK/SK pair of the source platform account.
• You have obtained AK/SK of the destination platform account. For details about how to obtain AKs and SKs, see Creating Access Keys (AK and SK).
• You have obtained the endpoints of IAM and OMS. For details, see Regions and Endpoints.
• You have obtained the region where the source bucket locates.
• The destination bucket has been created. For details, see Creating a Bucket.
• You have obtained the region where the destination bucket locates. For details, see Viewing Bucket Information.
• You have obtained the project ID. For details, see Obtaining a Project ID.

Procedure

1. Obtain the token of the IAM user.
   • API

     URI format: POST /v3/auth/tokens

     For details, see Obtaining a User Token Through Password Authentication.

   • Example request

     POST: https://{iam_endpoint}/v3/auth/tokens

     Obtain {endpoint} from Regions and Endpoints.

     Body:

     {
         "auth": {
             "identity": {
                 "methods": [
                     "password"
                 ],
                 "password": {
                     "user": {
                         "name": "username",
                         "domain": {
                             "name": "domainname"
                         },
                         "password": "******"
                     }
                 }
             },
             "scope": {
                 "project": {
                     "id": "0215ef11e49d4743be23dd97a1561e91"
                 }
             }
         }
     }

   In the response header, the value of X-Subject-Token is the token.

   X-Subject-Token:MIIDkgYJKoZIhvcNAQcCoIIDgzCCA38CAQExDTALBglghkgBZQMEAgEwgXXXXX...

2. Make a call to the API for creating a migration task to create a migration task.
   • API

     URI format: POST /v2/{project_id}/tasks

     For details, see Creating a Migration Task.

   • Example request

     POST: https://{oms_endpoint}/v2/{project_id}/tasks

     Obtain {endpoint} from Regions and Endpoints.

     Header:

     Content-Type: application/json
     X-Auth-Token: "Token"

     Body:

     {
     	"src_node" : {
     		"region" : "source_bucket_region",
     		"ak" : "source_ak",
     	"sk" : "source_sk",
     		"bucket" : "source_bucket",
     		"cloud_type" : "cloud_type",
     		"object_key" : ["01.png", "list.txt"]
     	},
     	"enable_kms" : false,
     	"description" : "",
     	"dst_node" : {
     		"region" : "destination_bucket_region",
     		"ak" : "destination_ak",
     		"sk" : "destination_sk",
     		"bucket" : "destination_bucket"
     	},
     	"enable_failed_object_recording" : true,
     	"enable_restore" : false,
     	"task_type" : "object"
     }

   • Example response

     {
             "id" : 200477729979132,
             "task_name" : "task_name"
     }

3. Make a call to the task viewing API to view the task status.
   • API

     URI format:

     GET /v2/{project_id}/tasks/{task_id}

     For details, see Querying a Migration Task.

   • Example request
