Learning AWS CDK

Prerequisites

• Install CDK toolkit (using npm):

npm install -g aws-cdk

• Check toolkit version:

cdk --version

---

Creating first CDK Project

• After creating a directory, we use cdk init to create a new cdk project:

cdk init sample-app --language typescript

Compiling typescript code

• Since TypeScript sources need to be compiled to JavaScript, every time we make a modification to our source files, we would want them to be compiled to .js.

• Open new terminal to start watching for changes:

cd cdk-workshop   

npm run watch

• This will start the TypeScript compiler (tsc) in “watch” mode, which will monitor your project directory and will automatically compile any changes to your .ts files to .js.

Project Structure

lib/cdk-workshop-stack.ts

..is where your CDK application’s main stack is defined.

bin/cdk-workshop.ts

..is the entrypoint of the CDK application. It will load the stack class defined in lib/cdk-workshop-stack.ts.

package.json

..is your npm module manifest.

cdk.json

..tells the toolkit how to run your app.

tsconfig.json .. is your project’s typescript configuration.

Synthesize a template

cdk synth

Bootstrap stack

cdk bootstrap

cdk app deploying

cdk deploy

• Note: if TTY is not enabled, use the command cdk deploy --require-approval never This works because the subcommand parameter is not quoted in the entrypoint script so the shell will split it on spaces.

---

cdk diff

• we can ask the toolkit to show us the difference between our cdk app and what's currently deployed

cdk diff
