Port for HTTP is 80. The rest, unless assigned by IANA, is fantasy. :-)

You can make all your (OpenStack) services run under
http://example.com/openstack, e.g. http://example.com/openstack/metric
for Gnocchi, if you want. So there's no good reason to assigne a port to
a service more than there is to assigne a hardcoded URL prefix.

So I think I'd agree with Haikel here. But ultimately, in the RDO case,
the packaging files should leverage a real WSGI Web server like uwsgi if
they want to start the service, rather than defaulting *all* packages to
the same pbr default. Which will conflict and is bad user experience.

Nobody asks what the default port of e.g. phpmyadmin. The same should go
with OpenStack services ultimately. Unfortunately, the bad habit has
spread from the early day of Nova and Swift using a port and not
providing a WSGI file.
