This image builds a runtime ZIP file containing a Java GraalVM binary for Amazon Linux. It is designed to work with a ShadowJar containing an http4k AWS Lambda function and, given a tasteful selection of technologies, should not require any customisation of the GraalVM configuration.
Basic usage for an example project. Arguments to the docker run command:
- UBERJAR_PATH = path the UberJar. This is loaded from inside the container at source/<UBERJAR_PATH>
- OUTPUT_ZIP_PATH (optional) = path to the output Zipfile. Defaults to source/function.zip
./gradlew shadowJar
docker run -v $(pwd):/source \
http4k/amazonlinux-java-graal-community-lambda-runtime:latest <UBERJAR_PATH> <OUTPUT_ZIP_PATH?>The Docker image itself includes 2 script files loaded from this repo:
- bootstrap - the standard bootstrap file used by the Aws Lambda runner. Detects and passes the lambda memory settings to the JVM.
- packageZip - takes the input ShadowJar (renamed to function.jar), uses
native-imageto create a native binary, and creates the function.zip package.
