AWS CDK Examples

This repository contains a set of example projects for the AWS Cloud Development Kit. Some examples are only available in TypeScript, there is a guide on how to read TypeScript code and translate it to Python here.

Table of Contents

  1. TypeScript examples
  2. Java examples
  3. Python examples
  4. JavaScript examples
  5. .NET examples

TypeScript examples

To run a TypeScript example, say my-widget-service:

$ npm install -g aws-cdk
$ cd typescript/my-widget-service
$ npm install
$ npm run build
$ cdk deploy  // Deploys the CloudFormation template

# Afterwards
$ cdk destroy
Example Description
api-cors-lambda-crud-dynamodb Creating a single API with CORS, and five Lambdas doing CRUD operations over a single DynamoDB
application-load-balancer Using an AutoScalingGroup with an Application Load Balancer
appsync-graphql-dynamodb Creating a single GraphQL API with an API Key, and four Resolvers doing CRUD operations over a single DynamoDB
classic-load-balancer Using an AutoScalingGroup with a Classic Load Balancer
custom-resource Shows adding a Custom Resource to your CDK app
elasticbeanstalk Elastic Beanstalk example using L1 with a Blue/Green pipeline (community contributed)

Java examples

To run the Java examples:

$ npm install -g aws-cdk
$ cd java/my-widget-service
$ mvn compile
$ cdk deploy

# Afterwards
$ cdk destroy
Example Description
fargate-load-balanced-service Starting a container fronted by a load balancer on Fargate
hello-world A demo application that uses the CDK in Java

static-site A static site using CloudFront
api-cors-lambda-crud-dynamodb Creating a single API with CORS, and five Lambdas doing CRUD operations over a single DynamoDB
classic-load-balancer Using an AutoScalingGroup with a Classic Load Balancer

Python examples

To run a Python example, say my-widget-service:

$ npm install -g aws-cdk
$ cd python/my-widget-service
$ pip install -r requirements.txt    # Best to do this in a virtualenv
$ cdk deploy                         # Deploys the CloudFormation template

# Afterwards
$ cdk destroy

JavaScript examples

Select the following link to see how to install and run the example.

Example Description
aws-cdk-changelogs-demo A full serverless Node.js application stack deployed using CDK. It uses AWS Lambda, AWS Fargate, DynamoDB, Elasticache, S3, and CloudFront.

.NET examples

Example Description
my-widget-service Use Lambda to serve up widgets
random-writer This sample application demonstrates some essential mechanisms of the AWS CDK for .NET. It uses AWS Lambda, DynamoDB, CloudWatch.

To run a .NET example, say my-widget-service:

$ npm install -g aws-cdk
$ cd csharp/my-widget-service
$ dotnet build src
$ cdk deploy  // Deploys the CloudFormation template

# Afterwards
$ cdk destroy
