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.

A quick Ansible example

As with other automation tools, Ansible started out by managing servers before expanding its ability to manage networking equipment. For the most part, the modules and what Ansible refers to as the 'playbooks' are similar between server modules and network modules, with subtle differences. In this chapter, we will look at a server task example first and draw comparisons later on with network modules.

The control node installation

First, let's clarify the terminology we will use in the context of Ansible. We will refer to the virtual machine with Ansible installed as the control machine or control node, and the machines being managed as the target machines or managed nodes. Ansible can be installed on most of the Unix systems, with the only dependency of Python 2.7 or Python 3.5+. Currently, the Windows operating system is not officially supported as the control machine. Windows hosts can still be managed by Ansible; they are just not supported...
