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 took a grand tour of the open source automation framework, Ansible. Unlike Pexpect-based and API-driven network automation scripts, Ansible provides a higher layer of abstraction called a playbook to automate our network devices.

Ansible was originally constructed to manage servers and was later extended to network devices; therefore, we took a look at a server example. Then, we compared and contrasted the differences when it came to network management playbooks. Later, we looked at the example playbooks for Cisco IOS, Juniper JUNOS, and Arista EOS devices. We also looked at the best practices recommended by Ansible if you are using the latest Ansible release, version 2.8.

In Chapter 5, The Python Automation Framework – Beyond Basics, we will leverage the knowledge we gained in this chapter and start to look at some of the more advanced features of Ansible, such as group variables, templates, and conditional statements.
