cli: docker images --digest image does not display digest

Description

The image digest is <none> if you specify the image.

Steps to reproduce the issue:

C:\Users\camer\tmp> docker images --digests
REPOSITORY          TAG                 DIGEST                                                                    IMAGE ID            CREATED             SIZE
mono                latest              sha256:55ce025f24578afe68cdf579dd3a42b9af7e4c729eadefa1f0a236d6387a8eb2   61351f52f2f9        3 weeks ago         531MB

C:\Users\camer\tmp> docker images --digests mono:slim
REPOSITORY          TAG                 DIGEST              IMAGE ID            CREATED             SIZE

This is another way to do it

$ docker image inspect <image_name_or_id> -f '{{.RepoDigests}}'

It looks like no one wants to fix the “show digest” command to actually show digests!

Ah the image has to be pushed before digest is calculated - see https://github.com/moby/moby/issues/32016

I can still reproduce (MacOS 13.2.1, docker 20.10.17) :

$ docker images --digests alpine

I encountered the same issue. RepoDigests returned from the daemon was empty. Is there any workaround?

FYI @shhsu

EDIT

I found the daemon wouldn’t return digest for local build images until I pushed the images.
