By: Kirill Shirinkin

Overview of this book

Terraform is a tool used to efficiently build, configure, and improve production infrastructure. It can manage 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 complete management of infrastructure with Terraform, starting with the basics of using providers and resources. This book 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. It finishes with the complete workflow of managing a production infrastructure as code – this is achieved with the help of version control and continuous integration. At the end of this book, you will be familiar with advanced techniques such as multi-provider support and multiple remote modules.

Moving infrastructure updates to the CI pipeline

Remember how we started this book with a discussion of Infrastructure as Code concepts? Well, if we want to go further treating infrastructure as a real code, then we could (and even should) apply all the same best practices currently existing in software development, and Continuous Integration is a big part of it. The idea behind CI (in case you missed all the buzz about it a few years ago) is to be able to test, build, and deploy your code regularly and automatically. The way it works is by using special software that takes care of all the tasks of making your software ready for production. You only need to define which tasks exactly are part of your CI and how to execute them.

Do you remember that we chose GitLab over GitHub for some features that GitHub lacks? The most important feature that GitLab has completely integrated into all development workflows and that GitHub doesn't have at all is GitLab CI. Yes, you can use Travis CI or Jenkins...
