This book is the fastest way to get up and running with Terraform, an open source tool that allows you to define your infrastructure as code and to deploy and manage that infrastructure across a variety of public cloud providers (e.g., AWS, Azure, Google Cloud, DigitalOcean) and private cloud and virtualization platforms (e.g. OpenStack, VMWare).
This is a hands-on-tutorial that not only teaches you DevOps principles, but also walks you through code examples that you can try at home. You'll go from deploying a basic "Hello, World" Terraform example all the way up to running a full tech stack (server cluster, load balancer, database) that can support a large amount of traffic and a large team of developers—all in the span of just a few chapters.
By the time you're done, you'll be ready to use Terraform in the real world.
This book is for Sysadmins, Operations Engineers, Release Engineers, Site Reliability Engineers, DevOps Engineers, Infrastructure Developers, Full Stack Developers, Engineering Managers, CTOs, and anyone else responsible for the code after it has been written. If you're the one managing infrastructure, deploying code, configuring servers, scaling clusters, backing up data, monitoring apps, and responding to alerts at 3AM, then this book is for you.
How DevOps is transforming the way we run software; an overview of infrastructure as code tools, including configuration management, orchestration, and server templating; the benefits of infrastructure as code; a comparison of Terraform, Chef, Puppet, Ansible, Salt Stack, and CloudFormation.
Installing Terraform; an overview of Terraform syntax; an overview of the Terraform CLI tool; how to deploy a single server; how to deploy a web server; how to deploy a cluster of web servers; how to deploy a load balancer; how to clean up resources you've created.
What is Terraform state; how to store state so multiple team members can access it; how to lock state files to prevent concurrency issues; how to isolate state files to limit the damage from errors; a best-practices file and folder layout for Terraform projects; how to use read-only state.
What are modules; how to create a basic module; how to make a module configurable; versioned modules; module tips and tricks; using modules to define reusable, configurable pieces of infrastructure.
Advanced Terraform syntax; loops; if-statements; if-else statements; interpolation functions; zero-downtime, rolling deployment; common Terraform gotchas and pitfalls.
Version control; the golden rule of Terraform; coding guidelines; Terraform style; automated testing for Terraform; documentation; a workflow for teams; automation with Terraform.
