In this sample, you'll build a native GraalVM image for running web workloads in AWS Lambda.

To build the sample on macOS (Apple silicon arm64)

You first need to build the function, then you will deploy it to AWS Lambda.

Step 1 - Build the native image

Before starting the build, you must clone or download the code in function-sample-aws-native.

1. Change into the project directory: spring-cloud-function-samples/function-sample-aws-native

2. Run the following to build a Docker container image which will be used to create the Lambda function zip file.

   docker build -t "al2-graalvm21:native-function" .
   

3. Start the container

   docker run -dit -v `pwd`:`pwd` -w `pwd` -v ~/.m2:/root/.m2 al2-graalvm21:native-function
   

4. In Docker, open the image terminal.

   Your working directory should default to the project root. Verify by running ls to view the files.

5. From inside the container, build the Lambda function:

   ./mvnw clean -Pnative native:compile -DskipTests
   

After the build finishes, you need to deploy the function.
