CDK fundamentals

To begin with CDK, we need to understand the following fundamentals:

  • The main sub-commands of CDK toolkit (aka AWS CDK CLI or cdk):

    • cdk init: Create a new AWS CDK TypeScript project
    • cdk bootstrap: Deploys the CDK toolkit stack into an AWS environment
    • cdk synth: Synthesizes and prints the CloudFormation template for this stack
    • cdk deploy: Deploys the CDK stack(s) into your AWS account

  • The two main components of a CDK project:

    • The bin directory: contains the CDK code for the CDK app.
    • The lib directory: contains the CDK code for the stacks and used constructs.

  • The main workflow when you works with a CDK project:

    You update CDK code -> You run cdk deploy -> cdk synth is run -> CloudFormation template is “synthesized” -> Resources are deployed to AWS.

Next, we will deploy an example CDK project to understand how everything works.
