java-lambda-test

A small project to experiment with deploying Java applications to AWS Lambda with Docker.

Overview

The project is built with:

• Docker
• Java 11
• Gradle
  • shadow plugin

The project will build and deploy a fat/uber JAR to the Lambda Docker container.

Usage

Included are a pair of basic shell scripts, build.sh and run.sh which will build and start the container locally:

1. Build the Docker image:
   • docker build -t java-lambda-test:latest -f Dockerfile .
   • Use Dockerfile.dev to just copy the locally built jar into the image for faster testing.
2. Run the Docker image:
   • docker run -p 9000:8080 java-lambda-test:latest
3. Use an API client or curl to invoke the Lambda:
   • curl -XPOST "http://localhost:9000/2015-03-31/functions/function/invocations" -d '{"name":"afwolfe", "id":1}'
