How to share images between projects

Overview

You may require the ability to use multiple projects, but may want to use custom images across those projects. Sharing images between projects enables you to create master images in a single project, and then share them into multiple other projects.

This article provides examples of how to share images between OpenStack projects in the same region.

Intended audience

This article is intended for anyone responsible for the design and implementation of applications and services deployed on UKCloud's OpenStack service. Users should be familiar with using the OpenStack dashboard and API or CLI.

Sharing images between projects

Note

You will require a RC file for both the source project and the destination project.

1. Source the source project RC file.

2. Locate the destination project:

   openstack project list

3. Locate the image you want to share:

   openstack image list

4. Set the image as shareable:

   openstack image set --shared image-id

5. Share the image with the destination project:

   glance member-create image-id dest-project-id

6. Source the destination RC file.

7. Check that the image share is pending:

   openstack image member list image-id

8. Accept the image share:

   openstack image set --accept image-id
