Lambda / Container / Puppeteer

Example of how to deploy an AWS Lambda function as a container containing Puppeteer, with CRPM.

This example uses one Lambda function to asynchronously invoke multiple instances of another Lambda function, which takes a screenshot of a website. This enables you to take several screenshots in parallel and scale horizontally. The screenshots are stored in an S3 bucket.

Instructions

cd infra

# Install and build the CDK application

npm run build

cdk bootstrap aws://unknown-account/unknown-region

# Deploy the CloudFormation stack
cdk deploy puppeteer
