Create an AWS Fargate service that puts to DynamoDB
This project contains a sample AWS Cloud Development Kit (AWS CDK) template for deploying an AWS Fargate service running on an Amazon Elastic Container Service (ECS) cluster with an Application Load Balancer in-front.
The AWS Fargate service makes puts to a DynamoDB table. This template uses a custom image without having to pre-push the image to Amazon Elastic Container Registry (ECR) or another container library. This makes use of the in-built ecs.ContainerImage.fromAsset method.
The custom image has a base route / for health checks and /additem for adding items. Environment variables like the DynamoDB table name and AWS region are passed to the image to enable it to put items to the DynamoDB table.
