LocalStack Demo: ECS Container App

Simple demo application illustrating ECS applications running locally using LocalStack. The application image is built using Docker and pushed to a local ECR registry.

Prerequisites

• LocalStack
• Docker
• make
• awslocal

Installing

To install the dependencies:

make install

App Details

Please refer to the templates/ folder for details about the CloudFormation templates for the ECS service.

Running

Make sure that LocalStack is started:

LOCALSTACK_AUTH_TOKEN=... DEBUG=1 localstack start

The following command builds and deploys the app locally via CloudFormation:

make deploy

Specifically, the script above runs the following steps:

1. Create a new ECR registry locally
2. Build the application Docker image (from the nginx base image)
3. Push the image to the ECR registry
4. Create the ECS cluster and infrastructure
5. Create and deploy the ECS application, which starts the container in you local Docker environment

You should see some logs and a success output in the terminal:

...
Sample app (nginx) successfully deployed.

Finally, the test app (nginx) should be accessible under the URL http://localhost:45139/ .
