Terraform - Up and Running: Writing Infrastructure as Code

Product Information

This book is the fastest way to get up and running with Terraform, an open source tool that allows you to define The rapid evolution of the DevOps industry, though still in its infancy, poses an interesting question. The myriad of tools associated with Terraform has set a precedent, and one can only wonder where the trajectory will take us. Given the ever-evolving nature of technology, this book presents an effective foundation for those wanting to stay ahead of the curve. Yevgeniy Brikman's "Terraform: Up and Running" is a stellar guide to one of the most game-changing tools in the DevOps landscape. The book, deserving of its 5 stars, delves deep into practical examples and offers invaluable tips for creating production-grade code. This ensures that readers not only understand the theory behind Terraform but can also implement best practices with confidence.

I have been using Terraform at work for a couple of weeks. The setup was created by co-workers and I wanted to dive into this book to learn a bit more about TF on top of what I've already learned via d2d work. through code examples that you can try at home. You'll go from deploying a basic "Hello, World" Terraform The author describes why and how should one use Terraform, the importance of the Infrastructure as Code in the first chapter. And step by step, chapter by chapter, the author gives the most of best practices of terraform, how to organize your infrastructure code and main problems you may encounter. The chapters explaining terraform are heavily on AWS, some may consider that a thumbsdown for the book, but as the author explained the reason for that, all those examples can be tested on a free tier AWS account, unless it is stated otherwise.Cloud native: With this approach, the idea is to try to use each cloud independently, leveraging its unique services as much as possible. There's also an open-source effort at https://github.com/brikis98/terraform... to port for GCP and Azure (at the time of writing this). this is not a book that'll teach you devops best practices which is a plus in terms of book length. To deploy into multiple clouds, you create multiple copies of different providers. Readers of the first two editions of this book often asked for examples of how to work with multiple clouds (e.g., AWS, Azure, GCP), but I struggled to find an example where it was practical to do this in a single module. Here’s why:

All the code is in the code folder. The code examples are organized first by the tool or language and thenTransparent portability: With this approach, the idea is to try to use all the clouds as one unified computing platform, abstracting away all the differences between cloud providers to make it easier to migrate a workload from one cloud to the other. Therefore, except for a few niche cases, I recommend the cloud native approach. This is also the approach that Terraform is designed for: you can use Terraform with multiple clouds, but you have to write separate code for each cloud, using the providers and resources native to that cloud. Therefore, even for multi-cloud deployments, it’s unusual to build a single Terraform module that deploys into multiple clouds (that is, uses multiple different providers in one module); it’s much more common to keep the code for each cloud in separate modules. This book helped me understanding how Terraform works and what are the strengths / weaknnesses (immutable, declarative, agentless and so on) providers (e.g., AWS, Azure, Google Cloud, DigitalOcean) and private cloud and virtualization platforms I’m excited to announce that the early release of Terraform: Up & Running, 3rd edition, is now available! The 2nd edition came out in 2019 and it is remarkable how much has changed since then: Terraform went through six major releases (0.13, 0.14, 0.15, 1.0, 1.1, and 1.2), most Terraform providers went through several major upgrades of their own (e.g., the AWS provider went from 2.0 to 3.0 and 4.0), and the Terraform community has continued to grow at a frantic pace, which has led to the emergence of many new best practices, tools, and modules.

Update, September 28, 2022: The final version of Terraform: Up & Running, 3rd edition has been published! Grab your copy now! It's a pretty good book to get you started with Terraform. It provides great best practices for using Terraform in your company you couldn't find in one place anywhere else. There are several ingredients to setting up a secure CI / CD pipeline for Terraform. The first ingredient is to handle credentials on your CI server securely. The 3rd edition of the book adds examples of using environment variables, IAM roles, and arguably the most secure option of all, OpenID Connect (OIDC). Chapter 6 includes an example of using OIDC with GitHub Actions to authenticate to AWS, via an IAM role, without having to manage any credentials at all: # Authenticate to AWS using OIDCIf you want an other provider, you'll have to manage yourself and probably won't benefit **that much** from the book. I really enjoyed the whole read. Apart from Appendix A, Recommended Reading section, which includes quite good resources too, the conclusion part of each chapter summarizes the aspects mentioned in that chapter, and explains the related footnotes in the chapter. Some of those footnotes were eminently interesting, some of them I already knew.

Inclusion of problems. I’d love to have an “Extra for Experts” of challenges for readers to solve to solidify their knowledge. The second ingredient is to strictly limit what the CI server can do once it has authenticated: for example, in the OIDC snippet above, you’ll want to severely limit the permissions in that IAM role. But then how do you handle the admin permissions you need to deploy arbitrary Terraform changes?

Table of contents

Terraform: Up & Running is now on its 3rd edition; all the code in master is for this edition. If you're looking This hands-on-tutorial, now in its 3rd edition, not only teaches you DevOps principles, but also walks you Terraform has become a key player in the DevOps world for defining, launching, and managing infrastructure as code (IaC) across a variety of cloud and virtualization platforms, including AWS, Google Cloud, Azure, and more. This hands-on second edition, expanded and thoroughly updated for Terraform version 0.12 and beyond, shows you the fastest way to get up and running. Well structured - We start with a “Hello World” example to get the reader up and running, then move onto more complex topics (shared state management, testing, modularization). The book finishes with a discussion of the very important subject of people management with Terraform - how do we introduce Terraform to a team and convince management to adopt this new technology? You built a module and you want to use it several times—in a loop, essentially—without having to copy and paste the code. However, Terraform 0.12 and below didn’t support count or for_each on module. The solution
