CreateCustomImage - Simple Application Server - Alibaba Cloud Documentation Center

Creates a custom image based on a snapshot of a simple application server.

Operation description

A custom image is created from 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.

Note

If you need the data on the data disk of a simple application server when you create a custom image, create a snapshot for the data disk first.

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 you can create is 3 times the number of simple application servers that you have, but cannot exceed 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 in addition to a system 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 the server are also released.
Resetting the system or changing the image of a simple application server clears the disk data on the server. Back up the data as needed.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
