404 returned on v2/_ping for docker registry

[devshorts]

I am trying to run a docker registry local and used the quickstart to execute:

docker run -d -p 5000:5000 registry:2 

and if I do a curl on the ping I get a 404 not found.

root@dom-docker akropp]# curl localhost:5000/v2/_ping
404 page not found
[root@dom-docker akropp]# curl localhost:5000/v2/
[root@dom-docker akropp]# docker exec docker-registry registry --version
registry github.com/docker/distribution v2.1.1

Any ideas? Seems like this should just work out of the box right?

I should mention that the registry seems to be working...

[root@dom-docker akropp]# docker push localhost:5000/centos
The push refers to a repository [localhost:5000/centos] (len: 1)

The ping endpoint for the registry is /v2/ not /v2/_ping
