OAuthenticator

Example of running JupyterHub with GitHub OAuth for authentication.

By default, this image uses oauthenticator.GitHub, but you can use a different class by setting OAUTH_CLASS in your environment. Other configuration parameters, including specific values for your oauth class, can be configured via environment variables. For convenience, we include instructions for GITLAB and GITHUB below.

This image uses DockerSpawner to launch user servers. The result is that each user gets their own isolated container in the server, using the docker image specified in the config. For other options (e.g. Kubernetes or local), check out: https://github.com/jupyterhub/jupyterhub#spawners

Variables

General variables

ADMINS=balkian,oaraque
OAUTH_CALLBACK_URL=http://hub.cluster.gsi.dit.upm.es/hub/oauth_callback
HOST_HOMEDIR=/mnt/home/{username} # {username} will be replaced by the actual OAuth user

Git lab variables:

GITLAB_HOST=https://lab.cluster.gsi.dit.upm.es/
GITLAB_CLIENT_ID=TheMaxiID
GITLAB_CLIENT_SECRET=TheMaxiSecret
OAUTH_CLASS=oauthenticator.gitlab.GitLabOAuthenticator 
DATASETS_DIR=/home/datasets # READ ONLY
COMMON_DIR=/home/common # To share files between users

GitHub variables:

GITHUB_CLIENT_ID=GHId
GITHUB_CLIENT_SECRET=GHSecret
OAUTH_CLASS=oauthenticator.github.GitHubOAuthenticator 

Docker-compose

This repository includes a docker-compose file to automate building and running the image. To use it, save your environment variables to .env.

Then, just build the image and run an instance with a single command:

docker-compose run --build

Docker-swarm

DockerSpawner works with the old docker-swarm standalone mode, just by mounting your swarm socket to /var/run/docker.sock. e.g.:

-v "/var/run/swarm.sock:/var/run/docker.sock"

If you are using the new swarm mode in docker, you might want to check out this issue: https://github.com/jupyterhub/dockerspawner/issues/215

Manual instructions

Build

Build the container with:

make build

Alternatively:

docker build -t gsiupm/jupyter-oauth:testing .

Run

Add your oauth client id, client secret, and callback URL to your env file (i.e. .env). Once you have built the container, you can run it with:

make run

Alternatively:

docker run -it -p 8000:8000 --env-file=env gsiupm/jupyter-oauth:testing

Which will run the Jupyter server.

SSL

To run the server on HTTPS, put your ssl key and cert in ssl/ssl.key and ssl/ssl.cert.

Useful tweaks

You can add resource limits, e.g.:

c.Spawner.mem_limit = '10G'

Known issues

If you recreate the jupyterhub image, the token for the jupyterhub server will change, and it may have trouble connecting to user containers. We've tried setting the token manually in the config, but it did not work.

As a workaround, you could remove the containers and access them again:

docker ps -a | grep 'jupyter-' | cut -d' ' -f1 | xargs docker rm

Unfortunately, all unsaved work will be lost
