Elastic Compute Service:ExportImage

Last Updated:Sep 29, 2024

Exports a custom image to an Object Storage Service (OSS) bucket in the same region.

Operation description

Usage notes

Before you export images, take note of the following items:

  • Make sure that you are familiar with the prerequisites and considerations. For more information, see Export a custom image.

  • The ImageFormat parameter is available only for the following regions: Japan (Tokyo), Australia (Sydney) Closing Down, Indonesia (Jakarta), Germany (Frankfurt), UAE (Dubai), US (Virginia), UK (London), Singapore, Malaysia (Kuala Lumpur), and US (Silicon Valley). Alibaba Cloud services will be discontinued in the India (Mumbai) region. By default, custom images are exported in the RAW format in regions where the ImageFormat parameter is unsupported.

  • Use Resource Access Management (RAM) to authorize Elastic Compute Service (ECS) to write data to OSS. To complete the authorization, perform the following operations:

    • Create a role named AliyunECSImageExportDefaultRole and attach the following policy to the role:

         {
           "Statement": [
             {
               "Action": "sts:AssumeRole",
               "Effect": "Allow",
               "Principal": {
                 "Service": [
                   "ecs.aliyuncs.com"
                 ]
               }
             }
           ],
           "Version": "1"
         }
      
    • Attach the AliyunECSImageExportRolePolicy system policy, which is the default policy that grants ECS the permissions to export images, to the AliyunECSImageExportDefaultRole role. For more information, go to the Cloud Resource Access Authorization page. You can also create a custom policy that contains the following content and attach the policy to the role:

           {
             "Version": "1",
             "Statement": [
               {
                 "Action": [
                   "oss:GetObject",
                   "oss:PutObject",
                   "oss:DeleteObject",
                   "oss:GetBucketLocation",
                   "oss:GetBucketInfo",
                   "oss:AbortMultipartUpload",
                   "oss:ListMultipartUploads",
                   "oss:ListParts"
                 ],
                 "Resource": "*",
                 "Effect": "Allow"
               }
             ]
           }
      

After you export the images, take note of the following items:

Each exported custom image is stored in the specified OSS bucket. You can download the custom image. For more information, see Download objects.
