Overview of this book

Go is the go-to language for DevOps libraries and services, and without it, achieving fast and safe automation is a challenge. With the help of Go for DevOps, you'll learn how to deliver services with ease and safety, becoming a better DevOps engineer in the process. Some of the key things this book will teach you are how to write Go software to automate configuration management, update remote machines, author custom automation in GitHub Actions, and interact with Kubernetes. As you advance through the chapters, you'll explore how to automate the cloud using software development kits (SDKs), extend HashiCorp's Terraform and Packer using Go, develop your own DevOps services with gRPC and REST, design system agents, and build robust workflow systems. By the end of this Go for DevOps book, you'll understand how to apply development principles to automate operations and provide operational insights using Go, which will allow you to react quickly to resolve system failures before your customers realize something has gone wrong.

Summary

In this chapter, you have learned the essential parts of the Go language. This has included handling errors, using Go concurrency, taking advantage of Go's testing framework, and an introduction to Go's newest feature, generics. The skills acquired in this chapter are essential for all future chapters.

You should now possess the ability to read Go code contained in the rest of the book. In addition, this chapter has given you the necessary skills to write your own Go code. We will use these skills to manipulate files in the filesystem, execute commands on remote machines, and build RPC services that can do a myriad of tasks. You will build chatbots in order to do chat-based operations (ChatOps) and write software to extend Kubernetes. The learnings here are truly foundational.

Next, we will look at how to setup your Go environment to compile code locally on your machine. Let’s get started!
