title: Nvidia-docker add folder to container
body: <p>I'm pretty new to docker containers. I understand there are ADD and COPY operations so a container can see files. How does one give the container access to a given directory where I can put my datasets? </p>
  
  <p>Let's say I have a /home/username/dataset directory how do I make it at /dataset or something in the docker container so I can reference it?</p>
  
  <p>Is there a way for the container to reference a directory on the main system so you don't have to have duplicate files. Some of these datasets will be quite large and while I can delete the original after copying it over .. that's just annoying if I want to do something outside the docker container with the files.</p>
