Container

In my previous post I showed how to build a .NET 5 library inside a docker image and deploy it to an AWS Lambda. This post is a small extension on that. I’m going to build a .NET 5 Web API application, turn it into a docker image, deploy it to an AWS Lambda, and connect an API Gateway to the Lambda to call the controller inside the application, inside the container, inside the Lambda!

A few months ago AWS released a feature allowing Lambdas to run container images, for larger applications this is easier to work with than a zip file or set of layers, it also lets you move your already containerized apps to Lambda with a small effort. This post shows how to get .NET 5 “Hello World” application running in this manner.
