Deploying a native executable Spring Boot application using GraalVM to AWS Lambda.

Overview

This project demonstrates deploying RESTful Spring Boot 3.2.2 application on AWS Lambda using two methods: deploying as a zip file and deploying as a docker image. It is based on the AWS sample repository.

Note for both ways of deployment, I manually uploaded the source code to seperate lambda functions. For the zip file deployment, the application is packaged locally using the script ./build-native-zip.sh and for docker image deployment, GitHub Actions workflow is used to deploy to Amazon ECR (Elastic Container Registry).

Dependencies

1. Java 21 (runtime)
2. Lombok

Prerequisite

If you would like to build and upload to lambda from your local system, Docker needs to be installed.

Docker Image Deployment

To deploy a docker image, execute cd ./backend and ./build-native-ecr.sh in your terminal. This script generates the docker image name server-graalvm21 tagged as native-web. You can view details about the image by running docker image ls in your CLI.

Zip File Deployment

To deploy a zip file, execute cd ./backend and ./build-native-zip.sh in your terminal. This script produces a zip file named server-0.0.1-SNAPSHOT-native-zip.zip in the root of project.
