Mastering Python Networking - Second 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 this second edition of Mastering Python Networking, 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 book begins by reviewing the basics of Python and teaches you how Python can interact with both legacy and API-enabled network devices. As you make your way through the chapters, you will then learn to leverage high-level Python packages and frameworks to perform network engineering tasks for automation, monitoring, management, and enhanced security. In the concluding chapters, you will use Jenkins for continuous network integration as well as testing tools to verify your network. By the end of this book, you will be able to perform all networking tasks with ease using Python.

Introduction to continuous integration

Continuous Integration (CI) in software development is a way to publish small changes to the code base quickly, in the context of tests and validation built-in. The keys are to classify the changes to be CI-compatible, that is, not overly complex, and small enough to be applied that they can be backed out easily. The tests and validation process is built in an automated way to gain a baseline of confidence that it will be applied without breaking the whole system.

Before CI, changes to the software were often made in large batches and often required a long validation process. It can be months before developers see their changes in production, receive feedback loops, and correct any bugs. In short, the CI process aims to shorten the process from idea to change.

The general workflow typically involves the following steps:

  1. The first engineer...
