Micronaut application launched as an AWS Lambda

• Micronaut
• Java 17
• Native image
• Maven
• AWS Lambda
• AWS API Gateway
• Docker

What works:

• GET requests
• GET requests with query params
• POST requests

Resources

Localstack https://localstack.cloud/

Micronaut https://guides.micronaut.io/latest/mn-application-aws-lambda-graalvm-maven-java.html

How to

Build a lambda function

./mvnw package -Dpackaging=docker-native -Dmicronaut.runtime=lambda -Pgraalvm

Launch Localstack (docker)

docker-compose up

Configure a function

./setup.sh

As a result, all AWS artifacts will be created (a lambda function, API resources and so on). At the end of the script a GET and POST requests are executed.
