Deploy a Micronaut application to AWS Lambda as an ARM64 native-image

[msailes]

I'd like to be able to build and deploy my Micronaut application to the ARM architecture on AWS Lambda.

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

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

gives me to following error on my MacBook Pro M1

I believe this is because https://github.com/micronaut-projects/micronaut-maven-plugin/blob/master/src/main/resources/dockerfiles/DockerfileAwsCustomRuntime specifically targets the x86 version of GraalVM.

We need to make OS and architecture variables as we do with Java version etc.

In the meantime, the workaround is to run:

./mvnw mn:dockerfile -Dpackaging=docker-native -Dmicronaut.runtime=lambda

To generate the Dockerfile, then copy it to the project's root and make the change yourself.
