I've been setting up Nginx Proxy Manager and am wondering, is there a reason the docker doesn't include a port mapping for port 3000 by default? Since it seems to be required for the admin interface to function correctly.
As it is I ran into some trouble because I had another service that happened to default to using port 3000. If the port was mapped then it would have detected the port was already allocated to another image and refused to start the service rather than requiring going into the logs to figure out why I was unable to login.
