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.

In this chapter, we covered a lot of ground. Building from our previous knowledge of Ansible, we expanded into more advanced topics such as conditionals, loops, and templates. We looked at how to make our playbook more scalable with host variables, group variables, include statements, and roles. We also looked at how to secure our playbook with the Ansible Vault. Finally, we used Python to make our own custom modules.

Ansible is a very flexible Python framework that can be used for network automation. It provides another abstraction layer separated from the likes of the Pexpect and API-based scripts. It is declarative in nature in that it is more expressive in terms of matching our intent. Depending on your needs and network environment, it might be the ideal framework that you can use to save time and energy.

In Chapter 6, Network Security with Python, we will look at network security with Python.
