Last week I published an overview of how complex (networking-wise) Docker Swarm services can get. This time let’s focus on something that should have been way simpler: running container-based services on a single Linux host.

In the first part of this article I’m focusing on the basics, including exposed ports, and published ports. The behind-the-scenes details are coming in a week or so; in the meantime you can enjoy (most of them) in the Docker Networking Deep Dive webinar.
