Plans Introduction

In this lesson, we will learn what Terraform plans are, how they work, and how you can use them in your Terraform project.

Terraform plans

A plan is essentially Terraform showing you how it plans to change the world to fit the desired state specified in your code. Terraform plans provide you with the following details:

  • What Terraform will create,
  • What Terraform will destroy, and
  • What Terraform will update.

This gives you an idea of what Terraform will do before you ask Terraform to do it. Terraform summarises how many creates, updates, and destroys it will do at the bottom of the plan.
