The custom image is a Baidu Cloud Compute system disk-based snapshot at a certain moment. In fact, it is a private image which is saved from the running Baidu Cloud Compute system disk, and can be viewed only by the user itself.

You can consider to create a custom image in the following scenarios. For example, redeploying a complicated initialization system, deploying a server with the same configuration for multiple times, or performing rapid deployment for large tests or software developed by software developers.

1. Enter the dedicated instance list, select a dedicated instance on which you want to create an image, and then click “More Operations” > “Create a Custom Image”.

2. Enter the image name in the pop-up dialog and then click "Ok" to complete the custom image creation.
3. After the custom image has been created, click the "Image" tab on the right navbar to view the image that has been created.

After the custom image has been created, you can “Create an Instance” on the custom image tab. When you create an instance through the custom image, the system regards the instance image as this custom image by default. Or you can select a public image or other service integrated-images according to your needs.
