Simple "Hello World" POC with :
- Spark Java (http://sparkjava.com/)
- Kotlin
- Gradle with Kotlin-dsl
- Docker with GraalVM (https://hub.docker.com/r/oracle/graalvm-ce/) for generating native-image
Just run :
./gradlew clean build
./gradlew docker
And after :
docker run
-p 4567:4567
--name graalvm-poc
com.tetragramato/graalvm-spark-kotlin:latest
Finally on your navigator :
http://localhost:4567/hello
Et voilà !!! You run a GraalVM native-image, with a simple service responding "Hello World".
The native-image is running in the same Docker container than GraalVM -> Need to run the native-image on another "clean" Docker Container.
