Currently AFAIK there is no easy way to do this as this information should be stored by index which private registry doesn't have. But depending on how you started registry you have 2 options:
- if you started registry without -v to store data in separate host folder you can try with
docker diff with this you should get info about changes in container fs. All pushed images should be somewhere in /tmp/registry/repositories/
- if you started registry with -v just check content of mounted directory on host
If you used "centos" as name it should be in /tmp/registry/repositories/library/centos. This folder will contain text files which describes image structure. Actual data is in /tmp/registry/images/.
