Terraform - Up and Running: Writing Infrastructure as Code

Product Information

On hindsight, without the proliferation of cloud, it would hard to see IaC taking hold as the languages would be so fragmented across each infra built out. 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. You’ve now had a small taste of just 5 of the problems that have been solved in the Terraform world in the last few years and are now covered by the 3rd edition of Terraform: Up & Running, including how to work with multiple regions, accounts, and clouds, how to control your provider versions, how to manage secrets securely with Terraform, how to set up a secure CI / CD pipeline, and how to do control logic with modules. Cloud native: With this approach, the idea is to try to use each cloud independently, leveraging its unique services as much as possible. Well written - Brikman is clearly an experienced writer and this practice shows. The book is enjoyable to read while presenting dense technical content.

Update the code to work with the current version of Terraform. Providers are now separated from the main repository and the way terraform init works has changed slightly. The code examples on Github are very clear, I found myself lost just following along in the book. I highly recommend that readers use the code examples while working through the book. Maturity. How Terraform has become more stable due to the Terraform 1.0 release, the growth of the community, and the HashiCorp IPO. This book is the fastest way to get up and running with Terraform, an open source tool that allows you to defineI 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. Terraform has emerged as 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, and Azure. This hands-on book is the fastest way to get up and running with Terraform. this is not a book that'll teach you devops best practices which is a plus in terms of book length. your infrastructure as code and to deploy and manage that infrastructure across a variety of public cloud Currently, this is the best introduction into Terraform that is on the market. It isn't perfect, but this book does a really good job at taking someone who has never installed Terraform or used it and getting them up to what I would call "intermediate" level of knowledge. I actually interviewed for several DevOps jobs that required Terraform experience by solely reading this book and following along with the tutorials. It covers all the main Terraform concepts and I was able to even impress my interviewers based off the knowledge from this book.

Inclusion of problems. I’d love to have an “Extra for Experts” of challenges for readers to solve to solidify their knowledge. 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 OIDC I've been using Terraform for almost two years right now, and I'd recommend this book to anyone who wants to increase their understanding on terraform and its best practices. What I would expect from the author to update in the next version of this book:The book does a very, very solid job of teaching you how to use terraform right and not mess with your state. However there is another approach presented on how to prevent state file concurrency issues by using a CI to apply server provisioning. Of course this is limited to good will and sanity of other team members still not running terraform apply by themselves since I am not aware of an option preventing terraform users of running apply at all. The entire book has also been updated to mark all input and output variables that could contain secrets with the new sensitive keyword, which was introduced in Terraform 0.14 and 0.15 to tell Terraform to never log these values, as they may contain sensitive data: variable "db_username" { through code examples that you can try at home. You'll go from deploying a basic "Hello, World" Terraform support a large amount of traffic and a large team of developers—all in the span of just a few chapters.

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.

Update, September 28, 2022: The final version of Terraform: Up & Running, 3rd edition has been published! Grab your copy now! To answer these questions, the 3rd edition of the book includes a brand new chapter: Chapter 7, Working with Multiple Providers. This chapter shows how to work with multiple Terraform providers to deploy to multiple regions, multiple accounts, and multiple clouds. 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?

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:This hands-on-tutorial, now in its 3rd edition, not only teaches you DevOps principles, but also walks you The biggest opportunity that I take away from the book is thinking more about the structure of the TF files. I think the template presented here is pretty good, scalable and at least easier to digest than what I'm currently working on. And we also came to the conclusion that TF state should be broken up into smaller, independent chunks. So that's cool. 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. Since this code comes from a book about Terraform, the vast majority of the code consists of Terraform examples in the
