You can use a custom image to create one or more simple application servers with the same or higher configurations.
Prerequisites
A custom image is created. For more information, see Create a custom image.
Usage notes
Before you proceed, note the following:
You can use a custom image to create simple application servers only in the same region.
When you create a server from a custom image, the sizes of the system disk and data disk cannot be smaller than the total disk capacity of the source image.
NoteIf you share a custom image that contains a data disk across accounts, the custom image received by the peer account does not contain the data disk.
Do not perform the following operations before the simple application server is created. Otherwise, the server creation will fail.
Delete the custom image.
Delete the source snapshot of the custom image.
Reset the system or replace the image of the source simple application server.
The Simple Application Server created from a custom image has been released.
After a custom image is released or deleted, you cannot reset the servers that were created from that image.
Procedure
You can use one of the following methods to create a simple application server.
Method 1: Create a server directly from an image
