terraform-aws-ecs-web-app

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

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: The master branch is used in source just as an example. In your code, do not pin to master because there may be breaking changes between releases. Instead pin to the release tag (e.g. ?ref=tags/x.y.z) of one of our latest releases.

Module usage examples:

without authentication - complete example without authentication
with Google OIDC authentication - complete example with Google OIDC authentication
with Cognito authentication - complete example with Cognito authentication
