# scala-graalvm-docker | ||
|
||
This project provides a collection of docker images to facilitate the usage of GraalVM by Scala projects, guaranteeing a consistent and reproducible environment where native images can be produced in an automated fashion. | ||
|
||
> "Make development more productive and run programs faster anywhere." - GraalVM | ||
|
||
## Goal | ||
|
||
Accelerate GraalVM's adoption during develop, test, and release phases of Scala projects. | ||
|
||
|
||
## Available | ||
|
||
Scala: 2.11.8 and 2.12.6 | ||
|
||
SBT: From 0.13.15 until 1.1.5 | ||
|
||
GraalVM: 1.0.0-RC1 | ||
|
||
List of tags: [scalaops/scala-graalvm:{tags}](https://hub.docker.com/r/scalaops/scala-graalvm/tags/) | ||
|
||
|
||
## How to use | ||
|
||
|
||
Automating the development, testing, and release process will vary based on the needs of a project, but the following example could fit all cases. This repo contains a `docker-compose-example.yml` as an example of how to use an image. | ||
|
||
|
||
```docker-compose | ||
version: '3' | ||
services: | ||
app: | ||
image: scalaops/scala-graalvm:scala-2.12.6-sbt-1.1.5-graalvm-1.0.0-rc1 | ||
command: ./generate-native-image-example.sh | ||
volumes: | ||
- .:/app | ||
- ~/.ivy2:/root/.ivy2 | ||
- ~/.sbt:/root/.sbt | ||
- ~/.coursier:/root/.coursier | ||
``` | ||
|
||
|
||
By opening the console and running `docker-compose run app`; the docker-compose file must be in the project's root level, docker-compose will pull the version `scala-2.12.6-sbt-1.1.5-graalvm-1.0.0-rc1` and we execute the `./generate-native-image-example.sh` when the container boots up. Also, notice that the we share the current directory and known artifact folders with the container to avoid having the container's SBT loading all artificats everytime. | ||
|
||
|
||
The `generate-native-image-example.sh`: | ||
|
||
```shell | ||
# Set distribution folder from first argument, otherwise default to `native` | ||
NATIVE_IMAGE_FOLDER=native-image | ||
if [ $# -gt 0 ]; then | ||
NATIVE_IMAGE_FOLDER=$1 | ||
fi | ||
|
||
# Create native-image folder if it doesn't exist, and clear the contents | ||
mkdir -p ${NATIVE_IMAGE_FOLDER} | ||
rm -rf ${NATIVE_IMAGE_FOLDER}/* | ||
|
||
# Create an .jar using sbt-assembly | ||
sbt -mem 2048 clean assembly | ||
|
||
# Move .jar to native-image folder | ||
find "." -name '*.jar' | while read APP_JAR; do | ||
mv $APP_JAR $NATIVE_IMAGE_FOLDER | ||
done | ||
|
||
# Go to native-image folder and generate the executables for each .jar | ||
cd $NATIVE_IMAGE_FOLDER | ||
|
||
find "." -name '*.jar' | while read APP_JAR; do | ||
echo "Processing .jar '$APP_JAR' on $NATIVE_IMAGE_FOLDER folder" | ||
native-image -J-Xmx2G -J-Xms2G --no-server -H:+ReportUnsupportedElementsAtRuntime -jar ${APP_JAR} | ||
done | ||
``` | ||
|
||
|
||
Creates a `native-image` folder in the project folder, triggers SBT's task `sbt assembly`, moves the created `.jar` to `native-image` folder, and at last but not least, generates the native image using GRAALVM `native-image` command. | ||
|
||
|
||
Once the executable is ready in the `native-image` folder, we can run it inside the very same container, by changing the `command` in the `docker-compose` to point to `./native-image/{GENERATED-EXECUTABLE-FILE}`, or ship it to S3, or create a new docker image and publish to AWS ECR, etc... what to do with the executable is matter of creativity. | ||
|
||
|
||
Note that we presume that the current Scala project is using [sbt-assembly](https://github.com/sbt/sbt-assembly) plugin, but any other plugin could be used, like [sbt-pack](https://github.com/xerial/sbt-pack), [sbt-native-packager](https://www.scala-sbt.org/sbt-native-packager/), [sbt-onejar](https://github.com/sbt/sbt-onejar), and [sbt-proguard](https://github.com/sbt/sbt-proguard). | ||
|
||
|
||
## Spark Job example | ||
|
||
|
||
The folder `spark-job-graalvm-example` contains an example where it uses the docker-compose and shell above. | ||
