terraform-aws-ecs-web-app

A Terraform module which implements a web app on ECS and supporting AWS resources.

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.

Usage

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest (which test and deploy the example on AWS), see test.

Other examples:

• without authentication - without authentication
• with Google OIDC authentication - with Google OIDC authentication
• with Cognito authentication - with Cognito authentication

Important

In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.
