How to pass arguments to Shell Script through docker run

I am new to the docker world. I have to invoke a shell script that takes command line arguments through a docker container.
Ex: My shell script looks like:

#!bin/bash
echo $1

Dockerfile looks like this:

FROM ubuntu:14.04
COPY ./file.sh /
CMD /bin/bash file.sh

I am not sure how to pass the arguments while running the container
