JupyterHub Apps Launcher
JupyterHub Apps Launcher is a generalized server launcher. The goal of this project is to support launching anything like say a Flask Server, FastAPI server or a Panel Dashboard via a user supplied command. Currently, the following frameworks are supported:
- Panel
- Bokeh
- Streamlit
- Plotly Dash
- Voila
- Gradio
- JupyterLab
- Generic Python Command
Installation
pip install jhub-apps
or via conda
conda install -c conda-forge jhub-apps
Development Installation
Install Dependencies
conda env create -f environment-dev.yml
pip install -e .
Starting JupyterHub
Set the following environment variable:
export JHUB_APP_JWT_SECRET_KEY=$(openssl rand -hex 32)
jupyterhub -f jupyterhub_config.py
Now go to http://127.0.0.1:8000/services/japps/ to access JHub Apps Launcher
API Endpoints
The Hub service is exposed via FastAPI endpoints. The documentation for the same can be accessed at: http://127.0.0.1:8000/services/japps/docs
To try out authenticated endpoints click on the Authorize button on the top right of
the above url and chose OAuth2AuthorizationCodeBearer and click on Authorize.
Running Tests
Unit Tests
pytest jhub_apps/tests
E2E Tests
pytest jhub_apps/tests_e2e -vvv -s --headed
Usage
JHub Apps has been tested with local JupyterHub using SimpleLocalProcessSpawner and with
The Littlest JupyterHub using SystemdSpawner.
- Install JHub Apps
pip install git+https://github.com/nebari-dev/jhub-apps.git
- Add the following in The Littlest JupyterHub's
jupyterhub_config.py
from tljh.user_creating_spawner import UserCreatingSpawner
from jhub_apps.configuration import install_jhub_apps
c.JupyterHub.bind_url = "<YOUR_JUPYTERHUB_URL>"
c.SystemdSpawner.unit_name_template = 'jupyter-{USERNAME}{JHUBSERVERNAME}'
c.JAppsConfig.apps_auth_type = "oauth" # or none (if you don't want authentication on apps)
c.JAppsConfig.python_exec = "python3"
# Pass in the path to jupyterhub config
c.JAppsConfig.jupyterhub_config_path = "jupyterhub_config.py"
# Either a static list of conda environments to show in the
# create panel apps form or a callable to fetch conda enviornments
# dynamically, e.g. from conda-store API
c.JAppsConfig.conda_envs = []
c = install_jhub_apps(c, UserCreatingSpawner)
