Mount Cifs shares in Jupyter Notebook/Lab JupyterHub environment

[Bernhard Jungwirth]

Hi,

I would like to mount a windows network share in my jupyter notebook. 

I have a setup with Jupyterhub and Jupyter Notebooks in Docker. 

In my notebook docker images cifs-utils  are installed: 

RUN apt-get install cifs-utils keyutils -y

I connect to the JupyterHub  server and start a notebook and in JupyterLab I opened the terminal and I executed a mount command: 

mount.cifs -o user=Domainuser,domain=DOMAIN,rw,noauto, //domain.com/home /home/joyvan/nethome

But this command ends with the message: 

Unable to apply new capability set. 

I have to add the following options to  the docker run command in JupyterHub setup:

–cap-add SYS_ADMIN --cap-add DAC_READ_SEARCH

How can i do this, nothing I have tried worked: 

I have tried it as extra_create_kwargs, c.DockerSpawner.environment and client_kwargs:

c.DockerSpawner.extra_create_kwargs.update({ 'command': spawn_cmd })

c.DockerSpawner.client_kwargs =  {'privileged': '' }

c.DockerSpawner.client_kwargs = {

    '--cap-add': 'SYS_ADMIN',

    '--cap-add': 'DAC_READ_SEARCH',

}

Thanks, 

Bernhard
