Environment data

Build of Visual Studio Code - Insiders: 1.62.0-insider Build of python-insider: v2021.12.1409662628-dev Build of jupyter-release: v2021.10.1001408933 Build of pylance-release: v2021.10.3 Build of jupyter Keymap-release: v1.0.0 Build of jupyter Notebook Renderers-release: v1.0.3

Expected behaviour

  1. Windows install instructions a. Install Docker Desktop onto a machine b. Create a folder with a file ‘Dockerfile’ in it. c. Mark the file to look like so:
ARG BASE_CONTAINER=jupyterhub/jupyterhub
FROM $BASE_CONTAINER

USER root

USER $NB_UID

a. From a command prompt (in the same folder as the Dockerfile), run docker build -t jupyterhubcontainer:1.0 .
b. Run docker container create --name jupyterhub jupyterhubcontainer:1.0 jupyterhub
c. From the docker desktop app, start the jupyterhub container.
d. From the docker desktop app, run the CLI
  1. From the new command prompt, run adduser testuser
  2. Follow the series of prompts to add a password for this user
  3. Open VS code
  4. Open a folder with a python file in it.
  5. Run the Python: Specify local or remote Jupyter server for connections command.
  6. Pick ‘Existing’
  7. Enter http://localhost:8000 (assuming the jupyter hub container was successful in launching)
  8. Reload VS code and reopen this folder. Run a cell in a python file.

Actual behavior

An error pops up when run cell image image
