This is a stable example. It should successfully build out of the box

This examples does is built on Construct Libraries marked "Stable" and does not have any infrastructure prerequisites to build.

The ALB is backed by an EC2 instance acting as frontend client and built-in ALB response rules that simulates mobile and application api

curl -H "Host: mobile.mydomain.com" [ALB-DNS-FQDN]/production

Resonse received

{"status":"succes","apiversion":"prod_mobile_v1"}

curl -H "Host: api.mydomain.com" [ALB-DNS-FQDN]/production

{"status":"succes","apiversion":"prod_api_v1"}

It is a Maven-based project, so you can open this directory with any Maven-compatible Java IDE, and you should be able to build and run tests from your IDE.

You should explore the contents of this template. It demonstrates a CDK app to create a multi-rule ALB, based on path and host headers.
More information on ALB and Path routing is available here https://docs.aws.amazon.com/elasticloadbalancing/latest/application/tutorial-load-balancer-routing.html

The cdk.json file tells the CDK Toolkit how to execute your app. This example relies on maven to do that.

• mvn package compile and run tests
• cdk ls list all stacks in the app
• cdk synth emits the synthesized CloudFormation template
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk docs open CDK documentation

Enjoy!
