Terraform: Getting Started

How to Install, Setup and Use Terraform

Sean Kane

  • Are there parts of your infrastructure that you still have to stand up manually or via a collection of scripts?
  • Do you struggle to keep documentation about that setup process current?
  • Do you dread the day when you need to spin up a new region for the business?

Terraform is a tool that makes it possible to document and automate the creation, modification, and destruction of almost anything that can be managed by an API. This means that it is finally conceivable to automate the management of everything that your software stacks needs to actually run in any environment, including cloud resources, DNS entries, CDN configuration, and much more.

This class will introduce you to Hashicorp’s open source and free Terraform tool and teach you everything that you need to know to get started using it to standardize and simplify the way that you define and manage all of your infrastructure resources.

What you'll learn-and how you can apply it

By the end of this live, hands-on, online course, you’ll understand: - How to use Terraform to simplify your ability to repeatedly setup, manage, and teardown complex infrastructure environments.

And you’ll be able to:

  • Write typical Terraform configuration files
  • Use Terraform to stand-up, modify, and delete infrastructure components.
  • Utilize remote state and additional data sources

This training course is for you because...

  • You need to understand how to simplify infrastructure management for engineers.

Prerequisites

  • Basic comfort with the Unix command line is helpful.
  • Basic comfort using REST APIs

Recommended preparation:

  • A modern computer and OS
  • Recent Linux, OS X, or Windows 10
  • Reliable and fast internet connectivity
  • Download and run the Hashicorp Terraform installer for your OS
