Mastering Python Networking - Fourth 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, Fourth edition, you'll embark on a Python-based journey to transition from a traditional network engineer to a network developer ready for the next generation of networks. This new edition is completely revised and updated to work with the latest Python features and DevOps frameworks. In addition to new chapters on introducing Docker containers and Python 3 Async IO for network engineers, 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 AWS and Azure cloud networking. You will use Git for code management, GitLab for continuous integration, and Python-based testing tools to verify your network.

Installing GitLab

GitLab is a powerful, all-in-one tool to handle the end-to-end DevOps collaboration tool. As we will see in a minute, it hosts the code repository and handles the code testing, deployment, and verification. It is one of the most popular DevOps tools used in the field today.

The company behind the technology, GitLab Inc., had its successful initial public offering on NASDAQ (ticket GTLB) in late 2021, https://techcrunch.com/2021/09/17/inside-gitlabs-ipo-filing/. The company’s success shows the strength of and sustainability of the technology.

We will only need a small set of its features to get up and running with a test lab. The objective is to familiarize ourselves with the overall flow of the steps. I encourage you to look at the GitLab documentation at https://docs.gitlab.com/ to get a sense of its features.
