How do I list images and tags in google container registry

Question

Looking for a way to use the gcloud commandline to get the tags of container engine registry images.

this command cloud docker search gcr.io/PROJECT/myimage returns NAME DESCRIPTION STARS OFFICIAL AUTOMATED PROJECT/myimage 0 but i want to see the tags used so far like the gcloud web console shows.

the machine I run this command on pulls images from docker hub, tags them, then pushes them to google container engine with gcloud docker push...

I suspect I may be asking how to make the local docker client do commands against both google repo and docker hub repo so I can get docker images listings

****** UPDATE: see https://stackoverflow.com/a/38061253/201911 for this capability in the latest release.

Answer 1

Let me tell you hack to relieve your pain:

ZONE=eu
PROJECT_ID=testproject
PROJECT_URL=gs://${ZONE}.artifacts.${PROJECT_ID}.appspot.com/containers/repositories/library

# this generates images list
gsutil ls $PROJECT_URL | sed -e 's#/$##' -e 's#.*/##' 

IMAGE_URL=gs://${ZONE}.artifacts.${PROJECT_ID}.appspot.com/containers/repositories/library/${IMAGE_NAME}/

# this generates tags list for specified image
gsutil ls $IMAGE_URL | sed -n '/\/tag_/ { s#.*/tag_##p }'

This will serve you in most of the cases. You will need read permissions to list files in that specific storage bucket in GCE.

gcloud container images list-tags gcr.io/PROJECT/myimage https://cloud.google.com/sdk/gcloud/reference/container/images/list-tags

Answer 3

This is not currently possible with gcloud. gcloud docker is just a wrapper around the docker command line tool, which doesn't easily expose the information you'd like for remote repositories.

At some point in the future, gcloud may support this feature.
