Mount samba drives on linux from the command line

This document covers how to (un)mount and access data on a samba drive from Ubuntu, using the command line and have it accessible for read/write access within docker jupyter lab instance.

Using cifs

Requirements

For this route, you will need:

  • The cifs tools. If you do not have them, you can install them:

sudo apt-get install cifs-utils

  • The address of the samba server you’d like to mount. For this example we will use <server-url> for the address, <drive> for the folder you want to mount and <username>

  • sudo rights

Mount the drive

First create an empty folder where you will mount the drive:

mkdir <mount-point>

To mount the drive, you can:

sudo mount -t cifs <server-url>/<drive> <mount-point> -o domain=<domain>,sec=ntlm,vers=1.0,username=<samba_username>,password=<samba_password>

Note that sec=ntlm,vers=1.0 may not be needed for your server or it may use different settings.

The drive is now mounted under the <mount-point> path and you can read from there. To have it accessible within docker, the <mount-point> should be within your current working dierectory which you pass as a volume to a container:

docker run --rm -ti --user root -e GRANT_SUDO=yes -e NB_UID=$UID -e NB_GID=100 -p 8888:8888 -v ${PWD}:/home/jovyan/work darribas/gds_dev:5.0 start.sh

Container will open shell, from which you have to start Jupyter lab with sudo access:

sudo jupyter lab --allow-root

If you want to start Jupyter with custom environment variables (those passes during docker run will not work since we’re starting Jupyter as root):

sudo DB_PORT=0000 DB_USER=user jupyter lab --allow-root

Unmount the drive

Simply run:

sudo umount <mount-point>
