Tomcat not running on docker image

I installed tomcat7 on the image using Dockerfile through the command :

MAINTAINER Abc Xyz <abc@xyz.com>
RUN apt-get -qq update
RUN apt-get -y install openjdk-7-jre
RUN apt-get -y install tomcat7 
EXPOSE 8080

When I build the image and try to run the following command :

sudo docker run -d -P abcxyz/tomcat service tomcat7 start

I don't get to see the tomcat page on the port to which it is mapped (say 49153)... And when I run as a bash in the image and I try :

service tomcat7 start

Then also it fails to start the tomcat7 server. I think that the problem is that image is unable to start the tomcat7 server. And I heard that docker images can't run any upstart services though I am not sure.

Anybody has any idea how to solve it? Thanks.

Solution

It's not working, because the container will work for as long as the program you specified is running. The service tomcat7 start command finishes immediately.
