Comment 3 for bug 1721975

If you could help update this, it would be really awesome - I appreciate it xiaods! The code is correct and the doc is out of date.

We could just update the glance example to describe "default" vs "public" port. However maybe a different example than glance would illustrate the point better now that image_registry has been split out as a different service?

oslo_messaging has different ports for "amqp" (5672) and "http" (15672)-- perhaps that would be a better example?
