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.

Building a pet store Terraform provider

Even though the Terraform provider registry (https://registry.terraform.io/) has almost every provider you can think of, there is a chance that a provider you need does not yet exist. Perhaps you want to use Terraform to interact with resources of a proprietary API internal to your company. If you want to manage resources that don't yet exist in the Terraform provider ecosystem, you will need to write a provider for that API. The good news is that writing a Terraform provider is relatively simple. The thoughtful folks at HashiCorp provide great documentation, SDKs, and tools to make building a provider a breeze.

In the previous sections, we learned the basics of Terraform and how to use providers to interact with resources in both local and external systems. We were able to build cloud resources to deploy a Linux web application running in a container.

In this section, we will build upon the previous sections and learn how to build...
