    Description

      Per the documentation,

      In order for Quay to get the list of tags in the remote repository, one of the following requirements must be met:

      An image with the "latest" tag must exist in the remote repository OR
      At least one explicit tag, without pattern matching, must exist in the list of tags that you specify

      When trying to mirror GCP images which don't have a "latest" tag, I indeed get the following.

      Now the enhancement request is to switch from 

      skopeo inspect ... snip ... docker://eu.gcr.io/k8s-artifacts-prod/autoscaling/cluster-autoscaler

       
      to

      skopeo list-tags docker://eu.gcr.io/k8s-artifacts-prod/autoscaling/cluster-autoscaler

      which does correctly give the tags. See also https://github.com/containers/skopeo/blob/main/docs/skopeo-list-tags.1.md .
