title: I run the docker images which start tomcat8 server but it don't start
body: <p>I have docker image which I create from my docker file. When I run the image it has able to run the tomcat server then the command prompt come back. That mean the process is terminated and I think the container stops. So when I  see <a href="http://localhost:8080" rel="nofollow noreferrer">http://localhost:8080</a> no tomcat page is appear. So I am not able find actual what is the problem. I am actually trying to to build custom java8, tomcat8 and maven as environment and I want to deploy my maven project in that tomcat server.
  Bellow is the Dockerfile to create image</p>
  
  <pre><code>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"]
  </code></pre>
  
  <p>I put 3 folder of java, tomcat, maven near Docker file so those are added.</p>
  
  <p>Now when I build the image and run the image the bellow log appear.</p>
  
  <pre><code>root@dhavalbhoot:/home/veni/Documents/dhaval_bhoot/docker_images/tomcat1#
    docker run -it -p 8080:8080 dhaval/tomcat:8.0.38
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>Using CATALINA_BASE:   /opt/tomcat8
  Using CATALINA_HOME:   /opt/tomcat8
  Using CATALINA_TMPDIR: /opt/tomcat8/temp
  Using JRE_HOME:        /opt/java8
  Using CLASSPATH:       
    \#/opt/tomcat8/bin/bootstrap.jar:/opt/tomcat8/bin/tomcat-juli.jar
  Tomcat started.
  
  root@dhavalbhoot:/home/veni/Documents/dhaval_bhoot/docker_images/tomcat1#
