README.md

This component provisions an AWS Redshift cluster and seeds relevant database information (hostnames, username, password, etc.) into AWS SSM Parameter Store.

Tip

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.

Watch demo of using Atmos with Terraform

Example of running atmos to manage infrastructure from our Quick Start tutorial.

Running Terraform Tests

We use Atmos to streamline how Terraform tests are run. It centralizes configuration and wraps common test workflows with easy-to-use commands.

All tests are located in the test/ folder.

Under the hood, tests are powered by Terratest together with our internal Test Helpers library, providing robust infrastructure validation.

Setup dependencies:

• Install Atmos (installation guide)
• Install Go 1.24+ or newer
• Install Terraform or OpenTofu

To run tests:

• Run all tests:

  atmos test run
  

• Clean up test artifacts:

  atmos test clean
  

• Explore additional test options:

  atmos test --help
  

The configuration for test commands is centrally managed. To review what's being imported, see the atmos.yaml file.

Learn more about our automated testing in our documentation or implementing custom commands with atmos.
