Thanks for this, I’m only just getting started, and am planning to run a few containers side by side, hopefully with several of them running traffic through a container running a VPN, and while I had read documentation around this, I was having trouble understanding just by reading it (I have trouble understanding some concepts unless I’ve drawn out a diagram or list or something to demonstrate what I’m trying to understand) so having a few diagrams helps.
I have a question around docker-networking scenario and adding it here due to context. I am setting up 2 instances (AWS ec2) with each running 3 containers of Prometheus/grafana/AlertManager. One of the 3 services needs peering with the other service on different host and I am using docker-compose (not swarm) to set these services up. From what I understood this is not possible with default docker-bridge network that compose brings up to tie this services? I tried exposing the ports but it still tries to refer to the docker ip subnet?

Useful info, thanks for posting, but needs some serious proofreading.

Good info provided in this article, however linking containers is deprecated. [User-defined networks](https://docs.docker.com/v17.09/engine/userguide/networking/#user-defined-networks) should be used instead.
