Building Microservices with Go

Creating custom bridge networks

Implementing a custom overlay network is beyond the scope of this book, however, understanding how you can create custom bridge networks is something that we should look at as Docker-Compose, which we are going to introduce later in this chapter, utilizes these concepts.

Like many of the Docker tools, creating a bridge network is quite straightforward. To see the currently running networks on your Docker engine, we can execute the following command:

$ docker network ls  

The output should be something like the following:

NETWORK ID          NAME                DRIVER              SCOPE8e8c0cc84f66        bridge              bridge              local               0c2ecf158a3e        host                host                local               951b3fde8001        none                null                local       

You will find that there are three networks created by default, which ...
