rm -rf /var/cache/apk/*

RUN mkdir /app
ADD ${APP_JAR_NAME}.jar /app/

EXPOSE 8080
ENTRYPOINT ["/bin/bash","-c"]

Answer 1

Just change version (FROM) to adoptopenjdk/openjdk11, from the Overview:

FROM adoptopenjdk/openjdk11:latest
RUN mkdir /opt/app
COPY japp.jar /opt/app
CMD ["java", "-jar", "/opt/app/japp.jar"]
