You can use a custom image to quickly create multiple cloud computers with identical settings, eliminating the need to repeat creation tasks. This topic describes how to create a custom image.
Background information
Images are region-bound resources. You cannot use images to create cloud computers across regions. When you create a custom image, make sure that the image and the cloud computer that you want to create from the image belong to the same region. For example, if you want to create a cloud computer in the China (Hangzhou) region, you must use a custom image from the China (Hangzhou) region.
You can create a custom image based on a cloud computer or snapshot. You can also import an image from your on-premises device to the Elastic Desktop Service (EDS) Enterprise console and use the imported image to generate a custom image.
You cannot delete an image that is being created.
The time that is required to create an image varies based on the size of data on the cloud computer that is used to create the image.
Avoid shutting down or restarting the cloud computer during custom image creation, as it will cause the process to fail.
Prerequisites
If you want to use a cloud computer or a cloud computer pool to create an image, make sure that the cloud computer or cloud computer pool is created. For more information, see Create cloud computers or Create and manage a cloud computer pool.
If you want to use a snapshot to create an image, make sure that the system disk snapshot is created. For more information, see Use snapshots (public preview).
Create an image by using a cloud computer
You can create an image by using a cloud computer to save and replicate its operating system or data. This image can then be used to create additional cloud computers with identical settings.
Log on to the EDS Enterprise console.
Select one of the following methods to create an image:
Create on the Images page
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Images page, click Create Image.
Create on the Cloud Computers page
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Cloud Computers page, find the cloud computer based on which you want to create an image and click the ⋮ icon in the Actions column. Then, click Create Image.
Create on the Cloud Computer Pools page
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Cloud Computer Pools page, find the cloud computer pool based on which you want to create an image and click its ID.
On the Cloud Computer Information tab, find the cloud computer that you want to use to create an image, click the ⋮ icon in the Actions column, and then click Create Image.
In the Create Image panel, configure the following parameters and click Create.
Parameter
Description
Image Name
Enter a name for the image. Make sure that the name meets the naming conventions.
NoteThe name must be 2 to 128 characters in length, and can contain letters, digits, colons (.), underscores (_), and hyphens (-). It must start with a letter but cannot start with
http://orhttps://.Clean Personal Residual Data
Specify whether to clean personal data. By default, Clean Personal Residual Data is turned on to prevent personal data and logon information from being retained in the image.
NoteIf you use an encrypted cloud computer, this parameter is unavailable.
Before you enable or disable this feature, take note of the following items:
Turn on Clean Personal Residual Data
The system clears user personal data, which may extend image creation time by approximately 20 minutes.
The following data is cleared:
Linux cloud computers
The cleanup only impacts generated image files. It will remove data from regular users and directories under the
/homepath, but will not affect root user data or system-installed applications.Windows cloud computers
The cleanup only impacts generated image files. It will remove user files and data, except for those in
C:\Users\AdministratorandC:\Users\Public. Data in these two directories, as well as installed applications and system data, will remain unaffected.
Turn off Clean Personal Residual Data
The system does not remove personal data. The data of the generated image is identical to the data on the cloud computer, potentially exposing personal information.Clean Personal Residual Data
Scope
Valid values:
System Disk and Data Disk: The image contains data from the system and data disks of the source cloud computer. Cloud computers created from this image will have the same data on their system and data disks as the source cloud computer.
System Disk Only: The image you create contains only data from the system disk of the source cloud computer. Cloud computers created from the image will have identical system disk data as the source cloud computer, but their data disks will be empty.
ImportantIf you create a custom image based on a Linux cloud computer and set Scope to System Disk and Data Disk, the Clean Personal Residual Data feature is unavailable.
Description
Enter a description for the image based on your business requirements. By default, if you do not specify this parameter, the image name is used as the image description.
Select Cloud Computers
Select a cloud computer as needed. This parameter is required if you create an image on the Images page.
Create an image by using a snapshot
A snapshot captures the data on a disk at a specific moment, enabling data backup and restoration. A snapshot allows you to create a custom image that captures the operating system and data of a cloud computer. This custom image can then be used to create additional cloud computers with identical settings.
Note that only the system disk of a cloud computer can be used to create a custom image.
Use one of the following methods to create a custom image:
Create on the Snapshots tab
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Cloud Computers page, find the cloud computer whose system disk snapshot you want to use and click its ID.
On the Snapshots tab, find the system disk snapshot that you want to use to create an image and click Create Image in the Actions column.
Create on the Snapshots page
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Snapshots tab, find the system disk snapshot that you want to use to create an image and click Create Image in the Actions column.
In the Create Image panel, configure the Image Name and Description parameters and click Create.
Create an image by using an imported image
You can create an image on your on-premises computer and import the image to the EDS Enterprise console to generate a custom image. For more information, see Import an image.
View and manage custom images
In the left-side navigation pane, choose . On the Custom Image tab, you can view the status and creation progress of images.
If an image is created, the state of the image changes from Creating to Available, and the creation progress of the image changes to 100%.
If an image fails to be created, the state of the image changes from Creating to Failed. In this case, you can click Delete in the Actions column to delete the image and try to create an image again.
What to do next
After you create a custom image, you can perform the following operations:
Create a cloud computer template based on the custom image. For more information, see Create and manage custom templates.
Use a cloud computer template that contains the custom image to create cloud computers or cloud computer pools. For more information, see Create cloud computers or Create and manage a cloud computer pool.
