DIY Terraform Basic Exercise

This exercise will help you learn basic Terraform concepts including modularization and variable management.

Exercise Overview

In this exercise, you'll start with a basic Terraform configuration that creates an S3 bucket with a lifecycle policy. The initial code contains hardcoded values. Your task will be to transform this code into a reusable module.

Starting Point

The initial code creates an AWS S3 bucket with the following characteristics:

• A bucket with a specific name
• A lifecycle rule that moves objects to Glacier storage after 90 days
• Object expiration after 365 days

Exercise Tasks

1. Review the initial code in main.tf

2. Create a module from the existing code:

   • Move the S3 bucket configuration into a folder of your own choosing
   • Replace hardcoded values with variables
   • Define appropriate outputs

3. Implement the following improvements:

   • Make the bucket name configurable
   • Make the lifecycle rule days configurable
   • Make the storage class transition configurable

Have fun!
