If you want a custom image to include the latest software and configurations, you can use CloudOps Orchestration Service (OOS) to update the image.
Background information
OOS provides the ACS-ECS-UpdateImage public template, which can be executed to update custom images. You only need to specify a source image, an instance type, and a Cloud Assistant script in the template. Then, an execution is automatically created for the template and runs to update the specified image and generate a new image.
The custom image update process involves the automatic creation of a temporary pay-as-you-go ECS instance. Make sure that you have sufficient account balance to pay for temporary resources.
The ACS-ECS-UpdateImage public template performs the following tasks in sequence to update the specified image:
Check the image name. Check whether the name of the new custom image is unique and complies with the naming conventions.
Prepare resources. Use parameters, such as the instance type and security groups, to create a temporary ECS instance from the image that you want to update, and then install Cloud Assistant Agent on the instance.
Update the environment. Call a Cloud Assistant-related API operation to run a custom shell, batch, or PowerShell script to update the application environment of the temporary ECS instance.
Create a custom image. Stop the temporary ECS instance and create a custom image from it.
Release resources. Release the temporary ECS instance to prevent unnecessary costs.
Procedure
Go to ECS console - Images.
In the top navigation bar, select the region and resource group of the resource that you want to manage.
On the Images page, click the Custom Images tab.
Find the custom image that you want to update. In the Actions column, choose

Complete the settings in the General Settings section.
