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.

The cloud platform is not responsible for the integrity or security of shared images. When you use a shared image, ensure that the image is from a trusted sharer.

Constraints

You cannot share private images that have been published in Marketplace.
You can share images only within the region where they reside. To share an image across regions, you need to replicate the image to the target region first.
A system disk image or data disk image can be shared with up to 128 tenants, projects, or organizations, and a full-ECS image can be shared with up to 10 tenants, projects, or organizations.

Currently, image sharing with an account or organization is available only in certain regions.
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.

Procedure

If you want to share a private image with another tenant, the procedure is as follows:

You obtain the project ID, account ID, or organization URN from the tenant.

For details about how to obtain a project ID or an account ID, see Obtaining Account, IAM User, Group, Project, Region, and Agency Information. For details about how to obtain an organization URN, see Viewing Details About an Organization.
You share an image with the tenant.
The tenant accepts the shared image.
After accepting the image, the tenant can use it to create ECSs.

If the image is shared with an account or organization, the tenant can skip this step.
