WORKDIR application
ARG JAR_FILE=target/app-2.0.jar
COPY $JAR_FILE application.jar
RUN java -Djarmode=layertools -jar application.jar extract

FROM openjdk:8u272-jdk
WORKDIR application
COPY --from=builder application/dependencies/ ./
COPY --from=builder application/snapshot-dependencies/ ./
COPY --from=builder application/spring-boot-loader/ ./
COPY --from=builder application/application/ ./
COPY docker-entrypoint.sh ./
RUN chmod +x docker-entrypoint.sh
