Setup Project

We will use Java Language in this project.

mkdir <DIR_NAME> && cd <DIR_NAME>
cdk init app --language java

There is a simple way to get a starter template for your project i.e. Bootstrapping

You need your account id and your region where CloudFormation will setup it's stack

aws --profile <PROFILE_NAME> --region <REGION_NAME> sts get-caller-identity
cdk bootstrap aws://<ACCOUNT_ID>/<REGION_NAME>

Welcome to your CDK Java project!

You should explore the contents of this project. It demonstrates a CDK app with an instance of a stack (AwsCdkStack) which contains an Amazon SQS queue that is subscribed to an Amazon SNS topic.

The cdk.json file tells the CDK Toolkit how to execute your app.

It is a Maven based project, so you can open this project with any Maven compatible Java IDE to build and run tests.

Useful commands

• 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!
