Create project directory #
Create an empty directory on your system:
mkdir cdk-workshop && cd cdk-workshop
cdk init #
We will use cdk init to create a new Java CDK project:
cdk init sample-app --language java
Output should look like this (you can safely ignore warnings about initialization of a git repository, this probably means you don’t have git installed, which is fine for this workshop):
Applying project template sample-app for java
# 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 (`CdkWorkshopStack`)
which contains an Amazon SNS topic that is subscribed to an Amazon SQS queue.
The `cdk.json` file tells the CDK Toolkit how to execute your app.
It is a [Maven](https://maven.apache.org/) based project, so you can open this project with any Maven compatible Java IDE to build and run tests.
## Tutorial
See [this useful workshop](https://cdkworkshop.com/50-java.html) on working with the AWS CDK for Java projects.
## 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!
Initializing a new git repository...
Executing 'mvn package'
✅ All done!
As you can see, it shows us a bunch of useful commands to get us started.
