Lambda DynamoDB APIGW solution with integration test

Overview

• IaC in AWS CDK
• DevOps tooling and makefile configuration
• Solution deploys to LocalStack and includes an integration test
• Solution deploys to AWS using the same IaC

LocalStack Requirements

• LocalStack Pro subscription

Deploy to LocalStack

Deploy with AWS CDK to LocalStack

Bootstrap AWS CDK Stacks on LocalStack

You need to do this once.

make local-awscdk-bootstrap

Deploy App Stack on LocalStack

This will deploy the resources.

make local-awscdk-deploy

Curl APIGW Url

make local-awscdk-invoke

Run test

This will run the integration test asserting the Lambda AppConfig and DynamoDB integrations work.

make local-awscdk-test

Deploy and Test in Integration Environment

To deploy and test in an integration environment, change all of the local-<command> commands above to integ-<command>.

Cleanup and restart LocalStack

make local-awscdk-clean restart-ls

Deploy to AWS

We use the same IaC pipelines to deploy to AWS! This is a very important point that LocalStack enables teams to test their IaC pipelines locally before ever deploying them to a live AWS environment.

Do this from your host machine. Not inside the GDC.

Install AWS cdk

npm install -g aws-cdk

Set Live AWS Credentials

However you set your credentials in your terminal, do it now.

Deploy the AWS CDK IaC App Stack

Bootstrap the account. Only need to do this once per account/region.

make sbx-awscdk-bootstrap

This will deploy the resources.

make sbx-awscdk-deploy

Invoke the Lambda in AWS

make sbx-awscdk-invoke

Destroy the CDK Stack in AWS

make sbx-awscdk-destroy
