Assignment 2 For Cloud Development

By Lucian Svelic

Setup

The application is intended to be used with Java 21, but should work with pretty much any version. That can be downloaded here:

• https://docs.aws.amazon.com/corretto/latest/corretto-21-ug/downloads-list.html

Manually configure SDK

If you are not using a more powerful editor which automatically configures the correct JDK, or if you want to manually configure it, it can be done like this:

Unzip the SDK in a location like C:\jdk\jdk11.0.13_8

You will then have to configure the java path in the file gradle.properties

Linux/Mac OS specifics

The CDK is configured to run gradle with the gradle wrapper. This might cause issues on linux/mac operating systems. If such a problem does occur, try changing cdk.json to use ./gradlew and also by running sudo chmod +x gradlew first. It is also a possibility with problems due to different line endings on linux/mac and windows. That should be fixed with sed -i.bak 's/\r$//' gradlew

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

Useful commands

• gradle build 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
• cdk destroy Destroy all created stacks

Enjoy!
