Jupyter Positron Server

Run Positron Server inside your Jupyter environment using jupyter-server-proxy.

Requirements

• Python >= 3.9
• positron-server installed and available in your PATH
• A valid Positron license key file and signing key

Configuration

Setup includes installing a proxy for running Positron and a verifier service to check license validity. The setup flow looks like:

1. Email academic-licenses@posit.co to request a signing key (signing-key.pem) and license file (license.lic). Free for currently enrolled students using Positron for coursework — see the Positron Education License Rider for eligibility.
2. Download the Positron Server binary and extract it to /opt/positron-server in the single-user image, then place license.lic at resources/activation/linux/<arch>/license.lic (chmod 600, root-only).
3. Install jupyter-positron-server in the single-user image.
4. Install jupyter-positron-verifier in the Hub's Python environment, and store signing-key.pem at /etc/positron/signing-key.pem (root-only).
5. Register jupyter-positron-verifier as a JupyterHub service in jupyterhub_config.py, and point c.Spawner.environment at its minting endpoint.
6. Restart JupyterHub, then click the "Positron" icon in the JupyterLab launcher.
