Build with
./gradlew jibDockerBuild
This will produce the image bentsolheim/distroless-java11-fontfail
Run with
docker run -it -p 8080:8080 bentsolheim/distroless-java11-fontfail
This should blow up on startup with an error.
If you adjust jib.from.image in build.gradle to something like openjdk:11.0.2-jdk-slim-stretch
the application will start up successfully and you should be able to download the generated xls-file with
curl http://localhost:8080 -O -J
The example will probably run fine in your local ide.
