i have a running docker container, the image its derived from does not have the vnc configured.

I want to configure the vnc on this container and want to access it from my window machine. Is it possible.

I have already gone through so many links but no one really have the details. I do not want to use the images from docker hub since i am creating my own docker image. But i am stuck with vnc as don't know how to proceed with that. Before configuring the vnc in docker file, i want to check it on a running container.

If someone can describe the steps to run the vnc on running container and way to access it from my local window machine using vnc viewer , that will be awesome.
