Not sure about sharing port numbers - you can do something like:

  docker -d -p 80:8000 repo/container

isn't this good enough? Can you give more detailed example?

How does that help? All this does is establish a local PAT; you can still only bind one application to port 80 on on the host. If you have more than one service that needs to listen to port 80 and be reached by clients, you're still out of luck.

This is a pretty easy solve...haproxy + consul + consul-template allows you to spin up a new container, register it with consul and have the consul-template watcher regenerate the haproxy config to route to the new port.

It's a little overkill if you're running it on a single machine, but in a real production environment, it's a pretty lightweight solution.

Easy in theory, but in practice, you have to configure and monitor it all. Adding components and orchestration logic is not cost-free.

Well it's not so hard. If there is good document steps for it. It's really abut getting consul working right.
