Managing Shared Image

Last updated: 2022-06-17 11:27:19

    Overview

    Tencent Cloud allows you to share custom images between Lighthouse and CVM. You can customize image sharing as needed to implement offline migration between them. You can also use a shared image to quickly create instances and then get the needed components from them or add custom content to them.

    Note
    • Shared images do not take up the quota of custom Lighthouse instance images.
    • A shared custom Lighthouse instance can be deleted only after sharing is canceled.

    Usage Limits

    • Custom images can be shared only between Lighthouse and CVM instances in the same region under the same account.
    • You cannot share the following custom images from CVM to Lighthouse:
    • Imported custom CVM instance images.
    • Custom images already shared from CVM to Lighthouse.
    • Custom images of entire CVM instances.
    • Custom images whose underlying operating system and version are not listed in Supported Operating Systems.
    • Custom images without Cloud-init installed.
