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 examined the traditional change management process and why it is not a good fit for today's rapidly changing environment. The network needs to evolve with the business to become more agile and adapt to change quickly and reliably.

We looked at the concept of continuous integration, in particular, the open source Jenkins system. Jenkins is a full-featured, expandable, continuous integration system that is widely used in software development. We installed and used Jenkins to execute our Python script based on Paramiko at periodic intervals with email notifications. We also saw how we can install plugins for Jenkins to expand its features.

We looked at how we can use Jenkins to integrate with our GitHub repository and trigger builds based on code-checking. By integrating Jenkins with GitHub, we can utilize the GitHub process of collaboration.

In Chapter 15, Test-Driven Development for Networks, we will look at test-driven development with...
