redirect location to docker registry port

Question

I setup a Docker registry in my Nexus with https connector on port 8123. I can successfully login to it:

docker login nexus.myserver.com:8123

But my goal is to use custom paths instead of port numbers, for example:

docker login nexus.myserver.com/myregistry1

So I tried to configure my apache conf like this:

Redirect /myregistry1 http://127.0.0.1:8123
ProxyPass /myregistry1 http://127.0.0.1:8123
ProxyPassReverse /myregistry1 http://127.0.0.1:8123

But when I try to login (docker login nexus.myserver.com/myregistry1), I get:

Error response from daemon: login attempt to http://nexus.myserver.com/v2/ failed with status: 404 Not Found

I'm not very familiar with apache, so any idea would be appreciated.
