Before we get any further, we really need to get deeply familiar with the conceptual Docker container connectivity, which is, unsurprisingly, in some ways very similar to building high-availability services with servers in a non-containerized world. Because of this, covering this topic in some depth will not only expand your understanding of Docker networking, but also help in generally building out resilient services.

A recap of Docker networking
In the previous chapter, we covered a bit of the Docker networking layout, so we will cover the main points here:
- By default, Docker containers run on an isolated virtual network on the host
- Each container has its own network address in that network
- By...
