Is it possible to query GitLab registry for all tags and digests like on Docker Hub?

Hi,

I’m looking for ways to efficiently query all tags and digests of a gitlab registry, like it is done against Docker Hub.

curl --silent ‘https://registry.hub.docker.com/v2/repositories/library/bash/tags/?page=1&page_size=100

Trying the same against the Gitlab registry;

This works;

curl --silent -H ‘Authorization: Bearer xxx’ https://gitlab.registry/v2/group/project/tags/list

Bit this results in 404’s;

curl --silent -H ‘Authorization: Bearer xxx’ ‘https://gitlab.registry/v2/group/project/tags/?page_size=100
or
curl --silent -H ‘Authorization: Bearer xxx’ ‘https://gitlab.registry/v2/group/project/tags/?page=1&page_size=100

Am I missing something?

Gr, J
