Shares or unshares a custom image.


You can share a custom image to ECS. When the configurations of your simple application server cannot meet your business requirements, or you want to use ECS instances to deploy your business, you can share your custom image to ECS to transfer your business from Simple Application Server to ECS.

Note The region in which the shared image resides in ECS is the same as the region in which the custom image resides in Simple Application Server.

You can unshare a custom image based on your business requirements or when you want to delete the custom image.

Take note of the following items:

  • After you unshare a custom image, you cannot query or use the custom image in the ECS console or by calling ECS API operations.
  • After you unshare a custom image, the system disks of the ECS instances that were created from the shared image cannot be re-initialized.

QPS limits

The queries per second (QPS) limit for a single user for the API operation is 10 calls per minute. If the number of calls to the API operation per minute exceeds the limit, throttling is triggered. As a result, your business may be affected. We recommend that you take note of the limit when you call this operation. For more information, see QPS limit.
