JupyterHub for Docker container course

This JupyterHub setup provides access to a web-based interactive docker terminal environment for use in e.g. Docker course settings. Issues around getting Docker to work on every participant's end device during the class are mitigated, and "bring your own working (!) Docker environment" is not anymore a requirement for taking part in the course. The setup ensures that teachers can focus solely on helping out with the course contents.

This setup is based on the "The Littlest JupyterHub" and leverages "Docker rootless" as provided by Docker Inc. to prevent issues around (1) privilege escalation (for sudo and docker-group Docker usage approaches) and (2) Docker daemon isolation. With this setup, every participant gets their own "safe to use" Docker container working environment, which also (mostly) resembles the Docker environment that would be presented on a local machine.

The setup was tested successfully with Ubuntu 22.04 and Ubuntu 24.04 releases.

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	#!/bin/bash
	# version 2 thanks to @dhx-mike-palandra
