Setting up a dev environment

It is possible to test the project locally without installing TLJH. Instead we use the jupyterhub Python package.

Requirements

Docker is used as a Spawner to start the user servers, and is then required to run the project locally.

Check out the official Docker documentation to know how to install Docker on your machine: https://docs.docker.com/install/linux/docker-ce/ubuntu/

Create a virtual environment

Using conda:

conda create -n plasma -c conda-forge python nodejs
conda activate plasma

Alternatively, with Python’s built in venv module, you can create a virtual environment with:

python3 -m venv .
source bin/activate

Install the development requirements

pip install -r dev-requirements.txt

# dev install of the plasma package
pip install -e tljh-plasma

# Install (https://github.com/jupyterhub/configurable-http-proxy)
npm -g install configurable-http-proxy

Pull the repo2docker Docker image

User environments are built with repo2docker running in a Docker container. To pull the Docker image:

docker pull jupyter/repo2docker

Run

Finally, start jupyterhub with the config in debug mode:

python3 -m jupyterhub -f jupyterhub_config.py --debug
