Red Hat Bugzilla – Bug 1258332
"man docker-pull" doesn't mention optional "digest" value
Last modified: 2015-09-28 14:59:10 EDT
Over at https://docs.docker.com/userguide/dockerimages/#image-digests, there is a short explanation of image digests and how they can be incorporated into a "docker pull" command -- there is no mention in "man docker-pull" of this feature.
I'm assuming this is some kind of checksum feature for reliability.
Please report this to docker. Not something we control.
