Network Automation with Go

By: Nicolas Leiva, Michael Kashin

Overview of this book

Go’s built-in first-class concurrency mechanisms make it an ideal choice for long-lived low-bandwidth I/O operations, which are typical requirements of network automation and network operations applications. This book provides a quick overview of Go and hands-on examples within it to help you become proficient with Go for network automation. It’s a practical guide that will teach you how to automate common network operations and build systems using Go. The first part takes you through a general overview, use cases, strengths, and inherent weaknesses of Go to prepare you for a deeper dive into network automation, which is heavily reliant on understanding this programming language. You’ll explore the common network automation areas and challenges, what language features you can use in each of those areas, and the common software tools and packages. To help deepen your understanding, you’ll also work through real-world network automation problems and apply hands-on solutions to them. By the end of this book, you’ll be well-versed with Go and have a solid grasp on network automation.

Marcus Hines

Marcus has spent his career focused on network device testing, test framework development, test automation and generally asking why things can’t be done differently. He started his career as a Network Engineer and he now focuses on engineering productivity across his organization. He helps maintain most of the OpenConfig organization’s repositories.

In a nutshell

I have become a very strong proponent of Go for general development for several key aspects:

  • Ease of use of language-provided tooling
  • Ramp-up speed for engineers joining projects
  • Speed of compilation and multi-platform support
  • Strongly typed language for static analysis with great build-time validations

Reasoning about automation

  • Testing and automation are basically the same thing.

Testing and automation can be distilled down to an ordered set of operations and validations to transform an input state and intent into an expected output state.
