Managing Secrets With Terraform and AWS Secrets Manager

Secret management is a critical component of any infrastructure. Secrets are sensitive pieces of information that should be protected from unauthorized access. These can include database credentials, API keys, or private IP addresses.

Terraform provides several ways to manage secrets, including environment variables, remote state, and integrations with secret stores like AWS Secrets Manager. As teams develop their infrastructure, they will need to consider how to manage secrets in a secure and scalable way.

In this lab, you will configure an Amazon RDS instance to use credentials stored in AWS Secrets Manager. You will also configure a remote state backend to store the .tfstate file in an Amazon S3 bucket and mask the values of sensitive environment variables.
