Docker - list images by tag

Docker docs give:

docker image ls [OPTIONS] [REPOSITORY[:TAG]]

but this assumes you'll specify a repo.

How do you list local images just by tag?

Nice question! I was playing with docker image ls and have found that you do not have to specify repository. The following actually work:

# displays images with tag: latest
docker image ls *:latest

# displays all images but not those with: <none>
docker image ls *:*

edit:

docker image ls *:latest has some inconsistencies. I noticed that some images are not displayed whereas docker image ls | grep latest shows them. I'll get back if I find out why...

Update by Santhosh V: It looks like a special character needs to be specified in the filter like docker image ls *\*:* for considering a \ in the image name

The following works on Docker version 20.10.6, build 370c289

docker images --filter=reference='*:sometag'

The official documentation can help you with more such filters.

You will use the Docker API, see the doc

https://docs.docker.com/registry/spec/api/#listing-image-tags

see also

https://gist.github.com/kizbitz/175be06d0fbbb39bc9bfa6c0cb0d4721

If the Docker API is on

http://myregistry.com

on the port 2375, then you will do something like

curl http://myregistry.com:2375/images/json

you will find in /images/json the same info as

docker images

will show

You can't just with the docker CLI on it's own. The CLI only supports listing all images (including or excluding intermediate layers), images matching a repo, or images matching a repo:tag.

In a shell then you can pipe to grep as has been mentioned in comments, otherwise you will have to parse the output of whichever method you use to list images.
