+# http4k/amazonlinux-java-graal-ce-lambda-runtime
+
+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:
+1. UBERJAR_PATH = path the UberJar. This is loaded from inside the container at source/<UBERJAR_PATH>
+2. OUTPUT_ZIP_PATH (optional) = path to the output Zipfile. Defaults to source/function.zip
+
+```shell
+./gradlew shadowJar
+docker run -v $(pwd):/source \
+http4k/amazonlinux-java-graal-ce-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-image` to create a native binary, and creates the function.zip package. 
+
+Images are hosted in [DockerHub](https://hub.docker.com/r/http4k)
