Description

docker images $IMAGE:latest doesn't show the digest of the latest image.

Steps to reproduce the issue:

1. Build an image

2. Tag it with:

   • registry.digitalocean.com/my-project/my-image:latest
   • registry.digitalocean.com/my-project/my-image:foobar

3. List all images:

   docker images registry.digitalocean.com/my-project/my-image --digests

4. This shows all the images, with their digests

   docker images --digests registry.digitalocean.com/my-project/my-image | head

5. Running the same command, for only the :latest image, the digest is not shown:

Describe the results you received:

docker images --digests registry.digitalocean.com/my-project/my-image:latest
REPOSITORY                                      TAG       DIGEST    IMAGE ID       CREATED          SIZE
registry.digitalocean.com/my-project/my-image   latest    <none>    60d6c85e5387   34 minutes ago   144MB

• Image with ID 60d6c85e5387 does have a digest in the full list, but not when queried by its tag
