JupyterHub: A multi-user server for Jupyter notebooks

Questions, comments? Visit our Google Group:

JupyterHub is a multi-user server that manages and proxies multiple instances of the single-user ~~IPython~~ Jupyter notebook server.

Three actors:

multi-user Hub (tornado process)
configurable http proxy (node-http-proxy)
multiple single-user IPython notebook servers (Python/IPython/tornado)

Basic principles:

Hub spawns proxy
Proxy forwards ~all requests to hub by default
Hub handles login, and spawns single-user servers on demand
Hub configures proxy to forward url prefixes to single-user servers

Dependencies

JupyterHub requires IPython >= 3.0 (current master) and Python >= 3.3.

You will need nodejs/npm, which you can get from your package manager:

sudo apt-get install npm nodejs-legacy

(The nodejs-legacy package installs the node executable, which is required for npm to work on Debian/Ubuntu at this point)

Then install javascript dependencies:

sudo npm install -g configurable-http-proxy

Optional

Notes on pip command used in the below installation sections:
- sudo may be needed for pip install, depending on filesystem permissions.
- JupyterHub requires Python >= 3.3, so it may be required on some machines to use pip3 instead of pip (especially when you have both Python 2 and Python 3 installed on your machine). If pip3 is not found on your machine, you can get it by doing:
```
sudo apt-get install python3-pip
```

Installation

JupyterHub can be installed with pip:

pip3 install jupyterhub

If the pip3 install . command fails and complains about lessc being unavailable, you may need to explicitly install some additional javascript dependencies:

npm install

If you plan to run notebook servers locally, you may also need to install the IPython notebook:

pip3 install "ipython[notebook]"

This will fetch client-side javascript dependencies and compile CSS, and install these files to sys.prefix/share/jupyter, as well as install any Python dependencies.

Development install

For a development install, clone the repository and then install from source:

git clone https://github.com/jupyter/jupyterhub
cd jupyterhub
pip3 install -r dev-requirements.txt -e .

In which case you may need to manually update javascript and css after some updates, with:

python3 setup.py js    # fetch updated client-side js (changes rarely)
python3 setup.py css   # recompile CSS from LESS sources

Running the server

To start the server, run the command:

jupyterhub

and then visit http://localhost:8000, and sign in with your unix credentials.

If you want multiple users to be able to sign into the server, you will need to run the jupyterhub command as a privileged user, such as root. The wiki describes how to run the server as a less privileged user, which requires more configuration of the system.

Getting started

see the getting started doc for some of the basics of configuring your JupyterHub deployment.

Some examples

generate a default config file:

jupyterhub --generate-config

spawn the server on 10.0.1.2:443 with https:

jupyterhub --ip 10.0.1.2 --port 443 --ssl-key my_ssl.key --ssl-cert my_ssl.cert

The authentication and process spawning mechanisms can be replaced, which should allow plugging into a variety of authentication or process control environments. Some examples, meant as illustration and testing of this concept:

Using GitHub OAuth instead of PAM with OAuthenticator
Spawning single-user servers with docker, using the DockerSpawner
