By default only admin users can pull images into a cluster managed by UCP.
Images are a shared resource, as such they are always in the swarm
collection. To allow users access to pull images, you need to grant them
the image load
permission for the swarm
collection.
As an admin user, go to the UCP web UI, navigate to the Roles
page, and create a new role named Pull images
.
Then go to the Grants page, and create a new grant with:
swarm
collection.Once you click Create the user is able to pull images from the UCP web UI or the CLI.
