Instructions and Navigations

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

packer {
 required_plugins {
 amazon = {
 version = ">= 0.0.1"

Following is what you need for this book: This book is for Ops and DevOps engineers who would like to use Go to develop their own DevOps tooling or integrate custom features with DevOps tools such as Kubernetes, GitHub Actions, HashiCorp Packer, and Terraform. Experience with some type of programming language, but not necessarily Go, is necessary to get started with this book.

With the following software and hardware list you can run all code files present in the book (Chapter 1-16).
