3. Default UI and add users

Change default UI to JupyterLab

I followed the instruction here https://tljh.jupyter.org/en/latest/howto/env/notebook-interfaces.html To change the default to be JupyterLab UI versus the classic Jupyter notebook UI. Open a terminal and run.

sudo tljh-config set user_environment.default_app jupyterlab

Then I had to reboot the instance from the AWS dashboard.

Add some users

Follow these instruction to add users. It describes adding admin users, but just uncheck the admin box to add regular users. https://tljh.jupyter.org/en/latest/howto/admin/admin-users.html Basically go to the JupyterHub main menu and look for the Admin tab. Click that and you'll see an option to add users.
