tmpnb, the temporary notebook service

Launches "temporary" Jupyter notebook servers.

WARNING: tmpnb is no longer actively maintained.

We recommend you switch to using JupyterHub.

Configuration option 1:

JupyterHub with tmpauthenticator

Configuration option 2:

BinderHub

tmpnb launches a docker container for each user that requests one. In practice, this gets used to provide temporary notebooks, demo the IPython notebook as part of a Nature article, or even provide Jupyter kernels for publications.

People have used it at user groups, meetups, and workshops to provide temporary access to a full system without any installation whatsoever.

Quick start

Get Docker, then:

docker pull jupyter/minimal-notebook
export TOKEN=$( head -c 30 /dev/urandom | xxd -p )
docker run --net=host -d -e CONFIGPROXY_AUTH_TOKEN=$TOKEN --name=proxy jupyter/configurable-http-proxy --default-target http://127.0.0.1:9999
docker run --net=host -d -e CONFIGPROXY_AUTH_TOKEN=$TOKEN --name=tmpnb -v /var/run/docker.sock:/docker.sock jupyter/tmpnb python orchestrate.py --container-user=jovyan --command='jupyter notebook --no-browser --port {port} --ip=0.0.0.0 --NotebookApp.base_url={base_path} --NotebookApp.port_retries=0 --NotebookApp.token="" --NotebookApp.disable_check_xsrf=True'

NOTE! This will disable Jupyter Notebook's token security. The option for container-user assures that the notebook will not run as a privileged user. You can set --NotebookApp.token to a string if you want to add a minimal layer of security.

BAM! Visit your Docker host on port 8000 and you have a working tmpnb setup. The -v /var/run/docker.sock:/docker.sock bit causes the orchestrator container to mount the docker client, which allows the orchestrator container to spawn docker containers on the host (see this article for more information).

If you are running docker using docker-machine, as is now the standard, get the IP address of your Docker host by running docker-machine ls. If you are using boot2docker, then you can find your docker host's ip address by running the following command in your console: boot2docker ip

If it didn't come up, try running docker ps -a and docker logs tmpnb to help diagnose issues.

Alternatively, you can choose to setup a docker-compose.yml file:

httpproxy:
  image: jupyter/configurable-http-proxy
  environment:
    CONFIGPROXY_AUTH_TOKEN: 716238957362948752139417234
  container_name:  tmpnb-proxy
  net: "host"
  command: --default-target http://127.0.0.1:9999
  ports:
    - 8000:8000

tmpnb_orchestrate:
  image: jupyter/tmpnb
  net: "host"
  container_name: tmpnb_orchestrate
  environment:
    CONFIGPROXY_AUTH_TOKEN: 716238957362948752139417234
  volumes:
    - /var/run/docker.sock:/docker.sock
  command: python orchestrate.py --command='jupyter notebook --no-browser --port {port} --ip=0.0.0.0 --NotebookApp.base_url={base_path} --NotebookApp.port_retries=0 --NotebookApp.token="" --NotebookApp.disable_check_xsrf=True'

Then, you can launch the container with docker-compose up, no building is required since they pull directly from images.

Advanced configuration

If you need to set the docker-version or other options, they can be passed to jupyter/tmpnb directly:

docker run --net=host -d -e CONFIGPROXY_AUTH_TOKEN=$TOKEN -v /var/run/docker.sock:/docker.sock jupyter/tmpnb python orchestrate.py --cull-timeout=60 --docker-version="1.13" --command="jupyter notebook --NotebookApp.base_url={base_path} --ip=0.0.0.0 --port {port}"

Note that if you do not pass a value to docker-version, tmpnb will automatically use the Docker API version provided by the server.

The tmpnb server has two APIs: a public one that receives HTTP requests under the / proxy route and an administrative one available only on the private, localhost interface by default. You can configure the interfaces (--ip, --admin_ip) and ports (--port, --admin_port) of both APIs using command line arguments.

If you decide to expose the admin API on a public interface, you can protect it by specifying a secret token in the environment variable ADMIN_AUTH_TOKEN when starting the tmpnb container. Thereafter, all requests made to the admin API must include it in an HTTP header like so:

Authorization: token <admin secret token here>

Likewise, if you only want to allow programmatic access to your tmpnb cluster by select clients, you can specify a separate secret token in the environment variable API_AUTH_TOKEN when starting the tmpnb container. All requests made to the public API must include it in an HTTP header in the same manner as depicted for the admin token above. Note that when this token is set, only the /api/* resources of the tmpnb server are available. All human-facing paths are disabled.

If you want to see the resources available in both the admin and user APIs, look at the handler paths registered in the orchestrate.py file. You should consider both APIs to be unstable.

Launching with your own Docker images

tmpnb can run any Docker container provided by the --image option, so long as the --command option tells where the {base_path} and {port}. Those are literal strings, complete with curly braces that tmpnb will replace with an assigned base_path and port.

docker run --net=host -d -e CONFIGPROXY_AUTH_TOKEN=$TOKEN \
           -v /var/run/docker.sock:/docker.sock \
           jupyter/tmpnb python orchestrate.py --image='jupyter/demo' --command="jupyter notebook --NotebookApp.base_url={base_path} --ip=0.0.0.0 --port {port}"

Using jupyter/docker-stacks images

When using the latest jupyter/docker-stacks images with tmpnb, you can use the start-notebook.sh script or invoke the jupyter notebook command directly to run your notebook servers as user jovyan. Substitute your desired docker-stacks image name in the command below.

docker run -d \
    --net=host \
    -e CONFIGPROXY_AUTH_TOKEN=$TOKEN \
    -v /var/run/docker.sock:/docker.sock \
    jupyter/tmpnb \
    python orchestrate.py --image='jupyter/minimal-notebook' \
        --command='start-notebook.sh \
            "--NotebookApp.base_url={base_path} \
            --ip=0.0.0.0 \
            --port={port} \
            --NotebookApp.trust_xheaders=True"'

Development

WARNING The Makefile used in the commands below assume your containers can be deleted. Please work on an isolated machine and read the cleanup target in the Makefile prior to executing.

git clone https://github.com/jupyter/tmpnb.git
cd tmpnb

# Kick off the proxy and run the server.
# Runs on all interfaces on port 8000 by default.
# NOTE: stops and deletes all containers
make dev

Troubleshooting

If you are receiving 500 errors after changing the proxy port, make sure that you are using the correct internal port (proxy port+1 unless you specify it otherwise).
