This topic describes how to create a custom image to store the data of a simple application server. The custom image can be shared to Elastic Compute Service (ECS) or used to create simple application servers that have the same configurations.
Prerequisites
A system disk snapshot of a simple application server is created. For more information,
see Manage snapshots.
Note If you need the data on the data disks of a simple application server when you create
a custom image, create a snapshot for the data disk first.
Background information
When you create a custom image, take note of the following items:
- The custom image and the corresponding simple application server reside in the same region.
- The maximum number of custom images that can be created is three times the number of simple application servers that you have, but cannot exceed 15.
- You can directly create a custom image only from the system disk snapshot of a simple application server. If you want a custom image to contain the data on the data disks of the simple application server, you must select data disk snapshots when you create the custom image.
- If a simple application server is released when it expires or a refund is performed for the server, the snapshots and custom images of the server are also released.
- If you reset or replace the operating system of a simple application server, the disk data, snapshots, and custom images of the server are all deleted. Back up your data before you reset or replace the operating system of your simple application server.
Procedure
What to do next
You can perform the following operations after the custom image is created:
