Overview of this book

Docker is an open source software platform that helps you with creating, deploying, and running your applications using containers. This book is your ideal introduction to Docker and containerization. You will learn how to set up a Docker development environment on a Linux, Mac, or Windows workstation, and learn your way around all the commands to run and manage your Docker images and containers. You will explore the Dockerfile and learn how to build your own enterprise-grade Docker images. Then you will learn about Docker networks, Docker swarm, and Docker volumes, and how to use these features with Docker stacks in order to define, deploy, and maintain highly-scalable, fault-tolerant multi-container applications. Finally, you will learn how to leverage Docker with Jenkins to automate the building of Docker images and the deployment of Docker containers. By the end of this book, you will be well prepared when it comes to using Docker for your next project.

Creating Docker networks

OK, you now know a lot about both the local and the remote network drivers, and you have seen how several of them are created for you when you install Docker and/or initialize swarm mode (or install a remote driver). But, what if you want to create your own networks using some of these drivers? It is really pretty simple. Let's take a look. The built-in help for the network create command looks like this:

# Docker network create command syntax
# Usage: docker network create [OPTIONS] NETWORK

Examining this, we see there are essentially two parts of this command we need to handle, the OPTIONS followed by the NETWORK name to make the network we wish to create. What are our options? Well, there are quite a lot, but let's pick out a few to get you going quickly.

Probably the most important option is the --driver option. This is how we tell Docker...
