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.

3 Getting Started with Go

In this chapter, we dive into Go basics, the characteristics that make it comparable to a dynamically typed language, but with the efficiency and safety of a statically typed, compiled language.

We also explore different Go packages to manipulate data in different formats and how to scale programs with Go's concurrency model. Being able to manipulate data effectively and to take advantage of all the resources of systems running multi-core processors are key elements to keep in mind when automating networks.

During this chapter, we cover the following key topics:

  • Go variable types
  • Go's arithmetic, comparison and logical operators
  • Control flow
  • Functions in Go
  • Interfaces in Go
  • Input and output operations
  • Decoding and encoding with Go
  • Concurrency
