cfn-modules: Fargate ALB to single container example

This example project demonstrates how an ALB can be placed in front of a single Docker container app running on Fargate. The following diagram illustrates the high-level architecture.

Prerequisites

1. Install Node.js 10.x
2. Create an S3 bucket where aws cloudformation package uploads the artifacts.
   1. Choose a unique bucket name, e.g. BucketName=cfn-modules-$Name-$Region
   2. Replace $Name with a unique name (e.g. your initials or company name)
   3. Replace $Region with your AWS default region (e.g. us-east-1)
   4. Create the bucket aws s3 mb s3://$BucketName

Usage

npm i
aws cloudformation package --template-file example.yml --s3-bucket $BucketName --output-template-file packaged.yml
aws cloudformation deploy --template-file packaged.yml --stack-name fargate-alb-single-container-example --capabilities CAPABILITY_IAM
aws cloudformation describe-stacks --stack-name fargate-alb-single-container-example --query "Stacks[0].Outputs[?OutputKey=='Url'].OutputValue" --output text

Open the URL in your web browser.

Don't forget to delete the stack once you are done with the demo:

aws cloudformation delete-stack --stack-name fargate-alb-single-container-example
