Simple Application Server:CreateCustomImage

A custom image is created based on a snapshot of a simple application server. You can use a custom image to create multiple simple application servers that have the same configurations. You can also share custom images to ECS and use the shared images to create ECS instances or replace the OSs of existing ECS instances. For more information about custom images, see Overview of custom images.

You must create a system disk snapshot of a simple application server before you create a custom image based on the snapshot. For more information, see CreateSnapshot .

Before you create a custom image, take note of the following items:

• The custom image and the corresponding simple application server must reside in the same region.
• The maximum number of custom images that can be maintained in an Alibaba Cloud account is triple the number of simple application servers in the account. The value cannot be greater than 15.
• You can directly create a custom image only based on the system disk snapshot of a simple application server. If you want a custom image to contain the data on the data disk of the simple application server, you must select a data disk snapshot when you create the custom image.
• If a simple application server is released due to expiration or refunds, the custom images that are created based on a snapshot of the server are also released.
• If you reset a simple application server by changing the application system or OS of the server or replacing the image of the server, the disk data on the server is cleared. Back up the disk data as needed.
