Description

https://docs.mirantis.com/docker-enterprise/v2.1/dockeree-products/dtr/dtr-user/manage-images/prevent-tags-from-being-overwritten.html Prevent tags from being overwritten

By default, users with read and write access to a repository can push the same tag multiple times to that repository. For example, when user A pushes an image to library/wordpress:latest, there is no preventing user B from pushing an image with the same name but a completely different functionality. This can make it difficult to trace the image back to the build that generated it.

To prevent tags from being overwritten, you can configure a repository to be immutable. Once configured,it will not be possible for anyone else to push another image tag with the same name.
