Overview of this book

Terraform is a tool used to efficiently build, configure, and improve the production infrastructure. It can manage the existing infrastructure as well as create custom in-house solutions. This book shows you when and how to implement infrastructure as a code practices with Terraform. It covers everything necessary to set up the complete management of infrastructure with Terraform, starting with the basics of using providers and resources. It is a comprehensive guide that begins with very small infrastructure templates and takes you all the way to managing complex systems, all using concrete examples that evolve over the course of the book. The book ends with the complete workflow of managing a production infrastructure as code—this is achieved with the help of version control and continuous integration. The readers will also learn how to combine multiple providers in a single template and manage different code bases with many complex modules. It focuses on how to set up continuous integration for the infrastructure code. The readers will be able to use Terraform to build, change, and combine infrastructure safely and efficiently.

Version control with Git 101


Feel free to skip this part if you are already familiar with version control and Git specifically.

Version Control System (VCS) simplifies work with constantly changing information, such as code. It allows us to store multiple versions of the same file, easily switch between them, and check who is responsible for which change. The most popular VCS today is Git, initially created to support Linux kernel development.

A VCS such as Git has many benefits:

  • You have access to all versions of all files in the Git repository at any time; it's almost impossible to lose any part of a piece of code or a previous state of the code.
  • Multiple developers can work on one project at the same time without interfering with each other's code and without fear of losing any changes made by colleagues. In Git, the possibilities of collaborative work are unlimited.

To create a repository, you've got to run git init in the project folder. To add files in it, first use git add file_name...
