ExportImage

Export your custom image to the OSS Bucket in the same region as the custom image.

Description

Exporting custom images created using system disk snapshots of market images is not supported.

Supports exporting custom images that include data disk snapshot information. The number of data disks cannot exceed 4, and the maximum capacity of a single data disk cannot exceed 500 GB.

You need to submit a work order and contact Alibaba Cloud to enable the export image function for you.

You need to authorize the cloud server ECS official service account to write OSS permissions through RAM:

Create role: AliyunECSImageExportDefaultRole (any other role name is invalid), set the following role policy for this role:

 {
   "Statement": [
     {
       "Action": "sts:AssumeRole",
       "Effect": "Allow",
       "Principal": {
         "Service": [
           "ecs.aliyuncs.com"
         ]
       }
     }
   ],
   "Version": "1"
 }

Add the default system permission policy: AliyunECSImageExportRolePolicy under the role AliyunECSImageExportDefaultRole. This policy is the default policy for exporting images provided by cloud server ECS. Users can also create custom policies. The permissions need to include:

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