Applicable scenarios

You can use a custom image you created or imported, or a shared image, to quickly purchase an ECS instance.

Description

Limits
Image type	Only custom images and shared images in the Available state support this feature.
Instance type	Currently, when creating an instance with a Windows image, you cannot select 3rd-generation instance types such as g3i, c3i, r3i that use the DPU architecture of the platform. For details of instance types, refer to Instance types.
Notes
After you create an instance with a Windows image, restart the new instance before logging in. When you create an instance of certain instance type with a Windows Server custom image, the platform automatically upgrades the Virtio driver. This improves the compatibility between the image and the instance and enhances system stability.

Procedure

Use the system volume image to purchase an instance

Use the whole image to purchase an instance

Click "Create Instances" in the "Actions" column to the right of the target image.

warning

The platform uses the selected image as the instance image, and you cannot change it on the instance creation page.

If the custom image belongs to a project, you need to use an account that has permission to operate the project to create instances from the image. The instances created from the image also belong to the project. For more information about how to authorize an account to operate a project, see Managing access to projects.

On the instance creation page, refer to Purchasing an ECS instance to create an instance.

tip

If you select a custom image created with an ESSD system volume for instance creation, the system volume type can only be specified as ESSD.

After you purchase an instance, refer to Subsequent operations to learn how to use ECS instances.
