DockerSpawner

Enables JupyterHub to spawn user servers in docker containers.

Setting up the spawner

Install dependencies:

pip install -r requirements.txt

Install to the system:

python setup.py install

DockerSpawner

Tell JupyterHub to use DockerSpawner by adding the following line to your jupyterhub_config.py:

c.JupyterHub.spawner_class = 'dockerspawner.DockerSpawner'

There is a complete example in examples/oauth for using GitHub OAuth to authenticate users, and spawn containers with docker.

SystemUserSpawner

If you want to spawn notebook servers for users that correspond to system users, you can use the SystemUserSpawner instead. Add the following to your jupyterhub_config.py:

c.JupyterHub.spawner_class = 'dockerspawner.SystemUserSpawner'

The SystemUserSpawner will also need to know where the user home directories are on the host. By default, it expects them to be in /home/<username>, but if you want to change this, you'll need to further modify the jupyterhub_config.py. For example, the following will look for a user's home directory on the host system at /volumes/user/<username>:

c.SystemUserSpawner.host_homedir_format_string = '/volumes/user/{username}'

For a full example of how SystemUserSpawner is used, see the compmodels-jupyterhub repository (this additionally runs the JupyterHub server within a docker container, and authenticates users using GitHub OAuth).

Using Docker Swarm

Both DockerSpawner and SystemUserSpawner are compatible with Docker Swarm. Simply add to your jupyterhub_config.py file:

c.DockerSpawner.container_ip = "0.0.0.0"

which will tell DockerSpawner/SystemUserSpawner to get the container IP address and port number from docker port.

Building the docker images

Single user notebook server

Build the jupyterhub/singleuser container with:

docker build -t jupyterhub/singleuser singleuser

or use docker pull jupyterhub/singleuser to download it from Docker Hub.

System user notebook server

Or the jupyterhub/systemuser container with:

docker build -t jupyterhub/systemuser systemuser

or use docker pull jupyterhub/systemuser to download it from Docker Hub.
