Prerequisites
A custom image is created. For more information, see Create a custom image.
Background information
Before you use a custom image to create simple application servers, take note of the
following items:
- The custom image can be used to create simple application servers only within the same region.
- When you use a custom image to create simple application servers, the system disk size specified for the simple application servers cannot be smaller than the size of system disk data contained in the custom image. If the custom image contains data of a data disk, the data disk size specified for the simple application servers cannot be smaller than the size of data disk data contained in the custom image.
- Before simple application servers are created from a custom image, do not perform
the following operations. Otherwise, the servers fail to be created.
- Delete the custom image.
- Delete the snapshot from which the custom image was created.
- Reset the operating system or replace the image of the simple application server from which the custom image is derived.
- Release the simple application server from which the custom image is derived.
- The created simple application servers cannot be reset after the custom image is released or deleted.
You can use one of the following methods to create simple application servers:
