Overview
You can share your private images with other tenants. The tenants who accept the shared images can use the images to create ECSs of the same specifications.
HUAWEI CLOUD is not responsible for the integrity and security of shared images. When you use a shared image, ensure that the image is from a trusted sharer.
Constraints
- You can share only private images that have not been published in Marketplace.
- You can share images only within the region where they reside. To share an image across regions, replicate the image to the target region and then share it.
- A system disk image or data disk image can be shared with a maximum of 128 tenants, and a full-ECS image can be shared with a maximum of 10 tenants.
- Encrypted images cannot be shared.
- A full-ECS image is shareable only when it is created from a CBR backup or from an ECS that has never had a CSBS backup.
Use a Shared Image
- Assume that A wants to share an image with B. The process is as follows:

If B is a DeC or multi-project user, B also needs to provide the project name to A.

- To share the same image with D, A can add D as the tenant who can use the image.

- When B has deployed services on the instances created from the shared image and does not need the image any longer, B can reject the shared image.
