I am running docker images that start the tomcat8 server, but it does not start

Question

I have a docker image that I create from my docker file. When I run the image, it can start the tomcat server, then the command line is returned. This means the process is ending, and I think the container is stopping. Therefore, when I see http: // localhost: 8080 , the tomcat page does not appear. Therefore, I can not find the actual problem. I'm actually trying to create custom java8, tomcat8 and maven as an environment, and I want to deploy my maven project on this tomcat server. Bellow is a Docker image creation file.

FROM scratch
FROM ubuntu:16.04

RUN mkdir /opt/java8
RUN mkdir /opt/tomcat8
RUN mkdir /opt/maven3

ENV JAVA_HOME /opt/java8
ENV CATALINA_HOME /opt/tomcat8
ENV M2_HOME /opt/maven3

ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/bin:$M2_HOME/bin

ADD jdk1.8.0_112 /opt/java8
ADD apache-tomcat-8.0.38 /opt/tomcat8
ADD apache-maven-3.3.9 /opt/maven3

EXPOSE 8080

CMD ["startup.sh", "run"]

I put 3 java, tomcat, maven folders near the Docker file so that they are added.
