Mastering Python Networking - Third Edition

By: Eric Chou

Overview of this book

Networks in your infrastructure set the foundation for how your application can be deployed, maintained, and serviced. Python is the ideal language for network engineers to explore tools that were previously available to systems engineers and application developers. In Mastering Python Networking, Third edition, you’ll embark on a Python-based journey to transition from traditional network engineers to network developers ready for the next-generation of networks. This new edition is completely revised and updated to work with Python 3. In addition to new chapters on network data analysis with ELK stack (Elasticsearch, Logstash, Kibana, and Beats) and Azure Cloud Networking, it includes updates on using newer libraries such as pyATS and Nornir, as well as Ansible 2.8. Each chapter is updated with the latest libraries with working examples to ensure compatibility and understanding of the concepts. Starting with a basic overview of Python, the book teaches you how it can interact with both legacy and API-enabled network devices. You will learn to leverage high-level Python packages and frameworks to perform network automation tasks, monitoring, management, and enhanced network security followed by Azure and AWS Cloud networking. Finally, you will use Jenkins for continuous integration as well as testing tools to verify your network.

Installing Jenkins

For the examples we will use in this chapter, we can install Jenkins on the management host or a separate machine. As indicated in previous chapters, my personal preference is to install it on a separate virtual machine. The virtual machine will have a similar network set up as the management host up to this point, with one interface for the internet connection and another interface for the VMNet2 connection to the VIRL management network.

The Jenkins image and installation instructions per operating system can be found at and

The following are the instructions I used to install Jenkins on the Ubuntu host. Jenkins does not require a lot of hardware power; a single vCPU and 2 GB of RAM is what I have used in the lab. It also requires either Java 8 or 11 to be installed. We will use OpenJDK-11 for our server:

$ sudo apt install openjdk-11-jre-headless
$ java --version
openjdk 11.0.4 2019...
