On this episode we have the amazing AWS Serverless Hero AJ Stuyvenberg and his dog Taco to dive deep into the world of Serverless Containers.
AJ showed us how its easy to use AWS Lambda Web Adapter, an open source tool, to run web application on AWS Lambda with docker containers and how you can quickly deploy an application using AWS App Runner.
Here are the
app.js and dockerfile files we used for today's deployment:app.js1
