link to images

[willkg]

With images hosted on Docker Hub, I can see a list of tags available. For example, here are all the tags for the testprovider image:

https://hub.docker.com/r/mozilla/oidc-testprovider/tags?name=testprovider

Is there a way to see all the tags for fakesentry and other images on us-docker.pkg.dev? If so, can we add links to the README? If not, is there a way to build an index somehow?

Not sure if the GAR is not treated as private registry only (or by default), I can e.g. list https://gcr.io/v2/google-containers/pause/tags/list but not https://gcr.io/v2/moz-fx-sumo-prod/sumo-prod/tags/list that looks empty for me.

(That's probably why most deployments push public images to dockerhub first, and only then pull, tag & promote them to GAR for deployments. Wasted space and bandwidth, but publicly visible.)

Given the IAM configured here for CI, guess some authenticated gcloud container images list-tags could log the data from automation.
