#+title: Clojure CDK Example

This is an example project for CDK development with Clojure.

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

** Stack

This example systhesises an SQS Queue and an SNS Topic and adds a

subscription for the topic

** Useful commands

 * `clj -M:test`     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

** Multi-Stack deployment

 * `cdk deploy StorageStack` deploy the storage stack

 * `cdk deploy TopicStack`   deploy the topic stack

 * `cdk deploy --all`        deploy all stacks

** How it works

[[https://github.com/weavejester/integrant][Integrant]] is the main tool behind this setup, it manages the dependencies

between resources and stacks, by using a simple configuration map {}

CDK Java depends on =software.amazon.awscdk.App= instance and related

=software.amazon.awscdk.Stack= instances

Integrant  is used to manage the dependencies between them. The following

is the configuration used by the integrant system.

#+begin_src clojure

  (def config

    {:app/instance   {}

     :stacks/topic   {:app      (ig/ref :app/instance)

                      :stack-id "TopicStack"}

     :stacks/storage {:app      (ig/ref :app/instance)

                      :stack-id "StorageStack"}

     :app/synth      {:app    (ig/ref :app/instance)

                      :stacks [(ig/ref :stacks/topic)

                               (ig/ref :stacks/storage)]}})

#+end_src

You can define more stacks and add them to the =:stacks= vector in =:app/synth=

Refer [[https://docs.aws.amazon.com/cdk/v2/guide/work-with-cdk-java.html#java-running][CDK Java documentation]] for more.

Enjoy!
