How to use arguments in DockerConfiguration Class to map ports during container run

I have a need to map ports of my Azure ML compute(instance or cluster) to a corresponding open port inside the Docker container. Essentially I want to be able to add the -p hostport:containerport option in my docker configuration. I am guessing I can use the arguments option of the DockerConfiguration class. Sadly, there is no illustration/documentation of how this can be done. Could you please help with a solution?
