Sharing Custom Images

Last updated: 2022-12-08 11:09:05

    Overview

    A shared image is a custom image that a user shared to other users. With a shared image, you can get the necessary components from other users and add your custom contents.

    Note

    Tencent Cloud does not guarantee the integrity or security of shared images. Please only use shared images from trusted sources.

    Limits

    • Each image can be shared with a maximum of 50 Tencent Cloud accounts.
    • You can not change the name and description of the images shared from others. They can only be used to create or reinstall CVM instances.
    • When you share an image to others, the shared replicas do not count against your image quota.
    • If you need to delete a custom image that is shared with others, you need to cancel all the sharing relations first. For more information, see Cancelling Image Sharing. You can not delete an image shared from others.
    • Custom images can only be shared with accounts in the same region as the source account. To share an image with users in another region, you need to copy it to the target region before sharing.
    • The shared images that you obtain from others cannot be re-shared.
