Getting Started with Terraform for Google Cloud (GSTGC)

Module 1: Introduction to Terraform for Google Cloud

This is an introductory module that covers the business need for Terraform. We’ll start with the basics by providing an overview of infrastructure as code (IaC), which is the basic concept for Terraform. We will explore how Terraform can be used as an IaC tool on Google Cloud and also cover its features and benefits. We’ll then look at how Terraform transforms lines of code into real infrastructure on Google Cloud.

Lessons:

• Infrastructure as Code
• Terraform Overview
• Using Terraform

Module 2: Terms and Concepts

In this module, we introduce you to HashiCorp Language and discuss the terms and concepts involved in authoring a Terraform configuration. We also explore some of the important Terraform commands involved in managing the terraform configuration. Upon completion of this module, you will be able to interpret what each code block means, create basic configuration files within Terraform and be able to explain the purpose of a few few important terraform commands and we will also explore what a Validator tool is.

Lessons:

• Terraform Configurations and the HashiCorp Language
• Author Phase Terms and Concepts
• Terraform Commands
• The Terraform Validator
• Demo - Terraform Workflow
• Lab: Infrastructure as Code with Terraform

Module 3: Writing Infrastructure Code for Google Cloud

In this module, you will explore more about resources, variables, and output resources. We will begin by exploring how to create infrastructure components using resources and then explore how Terraform handles dependencies within resources. While we have been covering resource creation by using hard-code resource arguments, we will explore how you can parameterize a given configuration using variables. We will explore the syntax to declare, define and use them within your configuration. We will then discuss how you can export resource attributes outside the resource declaration using output values. We will then wrap up the module by discovering how you can simplify code authoring using Terraform registry, and Cloud Foundation Toolkit.

Lessons:

• Introduction to Resources
• Meta-arguments for Resources
• Resource Dependencies
• Variables
• Variables Best Practices
• Output Values
• Terraform Registry and Cloud Foundation Toolkit
• Lab: Creating Resource Dependencies with Terraform

Module 4: Organizing and Reusing Configuration with Terraform Modules

You will explore what modules are, how to use them from a public registry, how to use modules to reuse configurations, and parameterize configurations using input variables. You will also explore how to use output values to access resource attributes outside of the module.

Lessons:

• Introduction to Terraform Modules
• Modules use cases and benefits
• Reuse Configurations with Modules
• Variables and Outputs
• Best Practices and a Real Time Scenario
• Lab: Automating the Deployment of Infrastructure Using Terraform

Module 5: Introduction to Terraform State

The module starts with an introduction to Terraform state. You’ll then learn about the different ways to store Terraform state. Later in the module you’ll explore the benefits of storing the state file in a remote location. While there are many remote locations in which you can store the state file, this module describes how to store it in a Google Cloud Storage Bucket. You’ll wrap up the module by learning best practices for working with state files.

Lessons:

• Introduction to Terraform State
• Storing State Files
• Terraform State Best Practices
• Lab: Creating a Remote Backend
