Prerequisites

This guide assumes familiarity with Terragrunt units, stacks, and HCL configuration. If you’re new to Terragrunt, the Quick Start, Overview and Terralith to Terragrunt guide are good places to start.

You will need:

• An AWS account with permissions to create IAM roles, S3 buckets, Lambda functions, DynamoDB tables, and an OIDC provider.
• A GitHub account.
• Git installed locally.

If you don’t have these prerequisites, you can sign-up or install them for free at the following links:

• AWS account sign-up
• GitHub account sign-up
• Git installation

Caution

When you first create an AWS account, you will be logged in as the root user of the AWS account. Never use this account for provisioning workloads. Create a separate administrator account using it, then log into that one to follow this guide.

Read the documentation on root users from Amazon for more information.
