How to share a mounted folder in Docker with its host?

Hi guys,
i was able to get an ubuntu version runnung in docker. Its is the tutum/ubuntu container. I was able to mount acd with FUSE via acd_cli successfully. My plan is now to share those mounted file with its host, where i am running plex. What is the best way to do so? Share it via SFTP or SMB. Or is there an even easier way`?

Best regards,
Tom
