title: Docker container running tomcat - could not access the server using the host IP address
body: <p>I am trying to build a docker container running tomcat from a docker file. Please find below the Dockerfile content:</p>
  
  <pre><code>FROM ubuntu:trusty
  MAINTAINER karthik.jayaraman
  VOLUME ["/tomcat/files"]
  ADD /files/tar/apache-tomcat-7.0.47.tar.gz /usr/local/tomcat
  ADD /files/scripts/. /tmp/tomcat_temp
  RUN ls /tmp/tomcat_temp
  RUN cp  -a /tmp/tomcat_temp/. /etc/init.d
  RUN chmod 755 /etc/init.d/tomcat
  RUN chkconfig --add tomcat &amp;&amp; chkconfig --level 234 tomcat on
  ADD /files/config   /usr/local/tomcat/apache-tomcat-7.0.47/conf/
  ADD /files/lib  /usr/local/tomcat/apache-tomcat-7.0.47/lib/
  ENV CATALINA_HOME /usr/local/tomcat/apache-tomcat-7.0.47
  ENV PATH $PATH:$CATALINA_HOME/bin
  EXPOSE 8080
  CMD ["service","tomcat","start"]
  </code></pre>
  
  <p>When i create the image and run a bash in the container, with the command "Service tomcat start", the server is started. I checked the catalina.out file and ensured that its running. But when i try the host IP on which docker is installed and access the port using the port number 8080, i could connect to tomcat page. But when i specify the internal IP address of the container - 172.24.0.7:8080, i could view the tomcat page. I guess the port forwarding is not properly. Can someone tell me the error i am making here.  </p>
