Mounting folder on local host

Hi

This is hopefully a really easy fix… i am completely new to Ubuntu and DIGITS.

I have managed to run DIGITS in the Nvidia container, however i am now having trouble mounting a local folder on the host for the datasets.

I have entered the below syntax to load the server

nvidia-docker run --name digits -d -p 8888:5000 -v /home/mark/data:/data:ro -v /home/mark/digits-jobs:/workspace/jobs nvcr.io/nvidia/digits:18.05

I am trying to look in /home/mark/digits-jobs/ there are two folders in there for the two different classifications.

Can you help identify what very silly mistake i am doing.

Thanks

Mark
