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.

Daniel Hertzberg

Daniel is a Senior Technical Marketing Engineer at Arista Networks. He’s been working within this field for double-digit years and has always had one foot in the door of networking and one foot in the door of automation/programmability. He writes Go on Visual Studio Code multiple times per week because of his success with network automation, cloud-native technologies, and OpenConfig.

I started off my automation not with network devices but with network overlays and network security with VMware NSX. NSX provides way too many options to click on to break the system. The same way that a network person could make a mistake and fat-finger a switch made it really easy for me to enter the same OSPF router ID within the same network... whoops! This was a REST API built with XML as an encoding and used Python requests to talk to it. At the time, most were using PowerShell to make this work, so even Python in this community was way outside the barriers of normalcy...
