Beanstalk Deploy Codebuild

This is an aws-cdk project where you can deploy your Node application on Elastic Beanstalk via Codebuild.

I have created a blog post on understanding how this works here.

Note: This configuration is for GitHub only. For Bitbucket, you can edit the source accordingly.

Prerequisites

Setup your access and secret keys via the aws-cli and with the profile name of your choice (the default profile is named default). The credentials generated should have access to creation of all resources mentioned else it won't work.

Steps

Rename the .example.env file to .env and replace all the values with your predefined values for your stack.

Note: All the variables are mandatory! Without that, the stack wouldn't work.

Run npm install
Run npm run deploy -- --profile profileName to deploy the stack to your specified region. You can omit the profile parameter if the profile name is default.
You can start the build from the console in Codebuild and your Node application works the Beanstalk provided URL!

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

In the cdk.json the platform parameter is passed to use the environment for Node 10. You can replace that with any environent of your choice.

You can get the list of platforms using aws elasticbeanstalk list-platform-versions.

Commands

npm run build compile typescript to js
npm run deploy deploy this stack to your AWS account/region specified in the .env
npm run watch watch for changes and compile
npm run test perform the jest unit tests
cdk diff compare deployed stack with current state
cdk synth emits the synthesized CloudFormation template
