Import custom image

Importing local physical image files into ECS is suitable for scenarios where business is deployed on the cloud. The imported custom image will appear in your custom image list in the corresponding region. You can use this image to create ECS instances and replace system disks.

Description

Importing a custom image is a relatively time-consuming task. The completion time depends on the size of the image file and the current number of concurrent import tasks, so you need to wait patiently.

When importing a custom image, the system will automatically generate a snapshot, and you can see the snapshot information in the snapshot list. Before the import image task is completed, the status of the snapshot will be displayed as failed. After the task is completed, the status is automatically updated to Available. The capacity of this snapshot is the size of the imported custom image file, and has nothing to do with the system disk size set when importing the custom image. Currently, snapshot capacity has been charged. For more details, please refer to the Snapshot Commercialization FAQ.
