All API calls to crane will follow the docker registry v1 protocol[1],
not the pulp API. The ping command is a valid API call to the docker
registry.

This is a Pulp call. Crane only serves docker registry API calls so
this is an expected failure. Try a registry call like...

curl http://localhost:5000/v1/repositories/<IMAGE/NAME>/images

or...

curl http://localhost:5000/v1/repositories/<IMAGE/NAME>/tags
