Integrating Posit Workbench with Jupyter Notebooks, Launcher, and Kubernetes#


These steps describe how to set up Posit Workbench installed outside a Kubernetes cluster to launch Jupyter Notebook and JupyterLab sessions into a Kubernetes cluster.


The architecture described on this page is not our recommended way of integrating Workbench and Kubernetes. We recommend using our Workbench helm charts to run both Workbench and the associated Jupyter Notebook and JupyterLab sessions entirely in a Kubernetes cluster.


This integration is intended to be performed on top of an installation of Workbench that has already been configured with Launcher and Kubernetes.

Step 1. Configure Launcher with Jupyter Notebooks#

  • Add the following lines to the Launcher Jupyter configuration file:

    File: /etc/rstudio/jupyter.conf
    The specification of default-session-container-image is optional as it allows for a particular image to be used by Jupyter sessions, otherwise the default-container-image setting in /etc/rstudio/launcher.kubernetes.profiles.conf will be used.

Step 2. Restart Workbench and Launcher Services#

  • Restart the services:

    $ sudo rstudio-server restart
    $ sudo rstudio-launcher restart

Step 3. Test Workbench with Launcher and Jupyter Notebooks#

  • From your browser, navigate to the Workbench interface and log in.
  • Select New Session and do the following:
  1. Give your session a name.
  2. In the **Editor** field, select either Jupyter Notebooks or JupyterLab as the IDE.
  3. Click Start Session.

Now, you can use the Jupyter Notebooks or JupyterLab interfaces.


Some local Jupyter configurations may prevent the JupyterLab session from correctly launching in Workbench. For example, setting a password in the files ~/.jupyter/jupyter-server-config.json or ~/jupyter/, will cause the JupyterLab session to start but not load through the Workbench interface. Commenting out the configuration in question is sufficient to restore expected functionality.

(Optional) Configure multiple Python versions or environments#

The Python integration steps described above result in a single Python environment that contains both core packages for Jupyter Notebooks as well as Python packages for end users.

While this is a simple approach, this setup can result in issues if end users want to use different versions of the same package or if some packages conflict with core packages for Jupyter Notebooks.

If you would like to use multiple versions of Python or different Python environments, or if you want to install Jupyter Notebook in a separate environment from Python packages for end users, then you can refer to the documentation for using multiple Python versions and environments with Jupyter.
