more nitpicky pedantry regarding docker on fedora 22 ... if i read
the man page for "docker-pull" on my f22 system, i see:
"This command pulls down an image or a repository from a registry. If
there is more than one image for a repository (e.g., fedora) then all
images for that repository name are pulled down including any tags."
note the reference to "all images" being pulled down. and the
example given seems to reinforce the notion that, if you specify
simply a repository, you'll get all corresponding tagged images:
docker pull fedora
Pulling repository fedora

docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
fedora rawhide ad57ef8d78d7 5 days ago 359.3 MB
fedora 20 105182bb5e8b 5 days ago 372.7 MB
fedora heisenbug 105182bb5e8b 5 days ago 372.7 MB
fedora latest 105182bb5e8b 5 days ago 372.7 MB
*however*, the explanation of the "-a" option seems to disagree with
that:
OPTIONS
-a, --all-tags=true|false
Download all tagged images in the repository. The default is false.
which suggests that, by default, you *don't* get all tagged images
unless you specify "-a".
and a quick test shows that, if i run "docker pull fedora", all i
appear to get is:
# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
docker.io/fedora latest ded7cd95e059 7 weeks ago 186.5 MB
#
so ... what am i misreading here? the man page seems just a touch
confusing and contradictory.
