/app/run.sh: line 7: java: command not found while running docker image

Question

I've created an image in docker and having /app/run.sh: line 7: java: command not found while trying to run this using sudo docker run com.project.question/question:1.0.0.Here's my run.sh

#!/bin/bash

SPRING_ACTIVE_PROFILE=${SPRING_ACTIVE_PROFILE:-"local-docker"}
GIT_BRANCH_LABEL=${GIT_BRANCH_LABEL:-"develop"}

java -jar -Djava.security.egd=file:/dev/urandom -    Dspring.profiles.active=${SPRING_ACTIVE_PROFILE} -    Dgit.config.active.branch=${GIT_BRANCH_LABEL} -Duser.timezone=Asia/Kolkata -XX:+PrintFlagsFinal $JAVA_OPTIONS -jar ${APP_JAR_NAME}.jar

Here's my DockerFile FROM openjdk:8u121-jdk-alpine FROM ubuntu:18.04

ENV APP_JAR_NAME question

RUN apt-get update
RUN apt-get install -y curl apt-utils wget unzip
RUN rm -rf /var/chache/apk/*
RUN mkdir /app

ADD ${APP_JAR_NAME}.jar /app/
COPY run.sh /app/
RUN chmod +x /app/run.sh

WORKDIR /app

EXPOSE 8080

ENTRYPOINT ["/bin/bash","-c"]
CMD ["/app/run.sh"]

I'm having following images in my docker I'm looking for the solution for hours but didn't find anything useful. Please help me figure this out. Thanks

The following doesn't merge images, it pulls 2 images and then continues the build based off the second image, Ubuntu, which doesn't include Java:

FROM openjdk:8u121-jdk-alpine
FROM ubuntu:18.04

You probably want the stretch based openjdk image, rather than Alpine, and then remove the second FROM line.

Thanks,do I need to install open-jdk using `DockerFile`? I'm a newbie in creating docker images – Jamshaid Sep 12 '19 at 18:11
would you please elaborate the difference between `stretch` based openjdk image and oracle jdk. Thanks – Jamshaid Sep 12 '19 at 18:15
Stretch is based on Debian, which Ubuntu is derived from. – BMitch Sep 12 '19 at 22:25
