Docker Image Not Loading on Localhost. Network, etc - docker

Question

I have been having really hard time figuring out the problem with my docker image not loading on localhost. I am using Docker for Windows 7. Following is some information regarding my docker image, network, etc, if it can be any helpful in proposing solutions.
I have EXPOSE 80 in my docker file. and listen 8080 in my shinyserver.conf file. I run my image by typing docker run -p 80:8080 imagename. It goes back to command line. Then I check http://localhost or http://localhost:8080, or http://172.17.0.1 or http://172.17.0.1:8080 or http://192.168.99.100 and no image shows up.
When I run docker ps there is no running container (makes sense, since image is not running anyway on localhost). All exited containers show with docker ps -a. There some containers that I haven't even created by show (i guess it comes with creating images).
I run docker inspect to find the IP address and here is what I get (there is no IP on fitfarmz which is my imagename)
$ docker inspect -f '{{.Name}} - {{.NetworkSettings.IPAddress }}' $(docker ps -aq)

I also got info on docker network:
$ docker network inspect bridge

Here is the dockerfile:
FROM r-base:3.5.0

# Copy configuration files into the Docker image
COPY shiny-server.conf /etc/shiny-server/shiny-server.conf
COPY /app /srv/shiny-server/
# Make the ShinyApp available at port 80
EXPOSE 80
# Copy further configuration files into the Docker image
COPY shiny-server.sh /usr/bin/shiny-server.sh
CMD ["/usr/bin/shiny-server.sh"]
And shinyserver.conf:
# Define the user we should use when spawning R Shiny processes
run_as shiny;
# Define a top-level server which will listen on a port
server {
# Instruct this server to listen on port 80. The app at dokku-alt need expose PORT 80, or 500 e etc. See the docs
listen 8080;
# Define the location available at the base URL
location / {
# Run this location in 'site_dir' mode, which hosts the entire directory
# tree at '/srv/shiny-server'
site_dir /srv/shiny-server;
# Define where we should put the log files for this location
log_dir /var/log/shiny-server;
# Should we list the contents of a (non-Shiny-App) directory when the user
# visits the corresponding URL?
directory_index on;
}
}
Here is the shiny-server.sh file:
mkdir -p /var/log/shiny-server
chown shiny.shiny /var/log/shiny-server
exec shiny-server >> /var/log/shiny-server.log 2>&1
Any ideas what is going wrong? I use the command: docker run -p 80:8080 fitfarmz to run the image.
