Terraform Quickstart: The Beginner's Guide to Infrastructure as Code

Why Learn Terraform?

Terraform is one of the top IaC tools used by companies building and scaling infrastructure in multi-cloud and hybrid cloud environments.

It works with major platforms like AWS, Azure, Google Cloud, and many other providers. It uses its own domain language, (HCL) which is human-readable and simple to learn.

Terraform helps you:

• Automate the setup of cloud services
• Version control your infrastructure
• Eliminate manual steps and human error
• Save time and money by avoiding repetitive tasks
• Reuse infrastructure code across teams and projects

Learning Terraform makes you a more valuable DevOps or Cloud Engineer.

What’s Inside This Book?

This beginner-friendly guide takes you through Terraform basics and prepares you to build real projects.

You'll learn how to:

• Understand what Infrastructure as Code means and why it's used to manage modern infrastructure.
• Install and configure Terraform CLI and use HCL syntax to write configuration files.
• Structure Terraform projects with .tf files for providers, variables, resources, and outputs.
• Split and reuse code using Terraform modules.
• Set up providers like GitHub, and create resources such as repositories with code.
• Connect Terraform to GitHub Actions for CI/CD automation of your deployments.
• Work with Terraform state files, and understand how local vs remote state works for collaboration and versioning.
• Import existing infrastructure (e.g., GitHub repos) and start managing it with Terraform.
• Use Terraform workspaces to separate environments like dev and prod.
• Test Terraform code using validation, static analysis, and Terratest.
• Understand common Terraform errors and debug them with built-in tools and troubleshooting techniques.
• Provision a managed PostgreSQL database on Render using open-source tools only.
