In the following the necessary steps are described how to setup a Jupyter Server on a Compute Cloud Instance that can be used for a course.

  • All accounts are temporary and only have access to this special instance.
  • The course instructor can set the password for the duration of the course and later on deactivate the accounts again.
  • The server is accessible from every client on the internet and the course instructor therefore should monitor the server for suspicious activity or change the password for access in case an account got compromized. However, the server is isolated from all other resources at LRZ like Linux Cluster or SuperMUC so that the amount of damage is small that can be performed by an attacker.

The course instructor should have some experience in setting up a linux OS on an empty machine and some basic understanding how linux works.

Basic Steps

Getting the Hardware

Setting up the Server

  • Start a new instance on the LRZ Compute Cloud where the number of cores should be the number of participants of the course. In general 20 cores should be fine. In doubt please send a ticket to
  • Choose Ubuntu for the OS.
  • You need a private/public key for login from your terminal/desktop
  • generate a floating IP for the internet and associate it with your server, either for the MWN or the whole internet.
  • Be aware that the system is accessible from the whole internet and can be an aim for hackers. Monitor the machine periodically and shelve it when it is not in use!

Installation of the software

  • Do not change the root password. By doing that root cannot be attacked from the outside
  • Use sudo for installation of the software
  • Download miniconda from conda as root and install it

bash history
$ sudo su

# make an installation folder for the jupyter installation
$ mkdir /opt/miniconda3
$ cd /opt/miniconda3

# get minicoda from the anaconda web site and extract it
$ wget
$ chmod +x ./
$ ./

# activate your installation and install jupyterhub
$ source /root/miniconda3/bin/activate
$ conda install jupyterhub

# start jupyterhub server
$ jupyterhub

Additional Information for the Installation

User administration

Provide user accounts as many as are needed for the course. Do not give them a login shell. By doing that, users can only use the jupyter hub interface to login.

bash history
# add participants of the course

$ useradd -m participant1
$ passwd participant1

add as many users you want. They can access jupyterhub with the username: participant1 and password. Change the names as you wish.

Tipps and tricks

These commands come in handy for setting user passwords and cleaning up user directories after the course:

bash history
$ python
>>> import os
# create 20 users (user0, user1, .., user19)
>>> [os.system(f"useradd -m user{i}") for i in range(20)]
>>> [os.system(f"echo user{i}:NEW_SECRET_PASSWORD | chpasswd") for i in range(20)]
# create an admin0 user
>>> os.system(f"useradd -m admin0")
>>> os.system(f"echo admin0:NEW_SECRET_PASSWORD | chpasswd")
# create a folder for course material for each user which is owned by admin0
>>> os.system("mkdir /home/admin0/course_material")
>>> [os.system(f"ln -s /home/admin0/course_material /home/user{i}/course_material1") for i in range(101)]
