Nun noch folgenden Befehl ausführen um JupyterHub-Server zu starten.

docker compose up -d --build

Öffne `http://localhost:8000` in deinem Browser und melde dich an (oder registriere ein neuen Benutzernamen)

Es gibt verschiedene Methoden um ein JupyterHub Server zum laufen zu bekommen folgend die Notizen des ersten Versuchs.

Zur Server Subdomain würde als erstes die IP 80.147.0.159 mit hub.bergemann-hoehne.com gut passen. Falls noch eine zweite Subdomain möglich ist sozusagen als Meisterstückadresse wäre ibex.spielwiese.bergemann-hoehne.com super wobei spielwiese auch durch beliebige Domainnamensyntax variabel sein kann. Diese zweite geht auf die IP 185.89.38.58

the FirstUseAuthenticator is enabled by default in TLJH.

sudo tljh-config set auth.type firstuseauthenticator.FirstUseAuthenticator
sudo tljh-config reload

Users who are currently logged in will continue to be logged in. When they log out and try to log back in, they will be asked to provide a username and password. Users changing their own password

Users can change their password by first logging into their account and then visiting the url <your_server_ip>/hub/auth/change-password.

Allowing anyone to log in to your JupyterHub

By default, you need to manually create user accounts before they will be able to log in to your JupyterHub. If you wish to allow any user to access the JupyterHub, run the following command.

tljh-config set auth.FirstUseAuthenticator.create_users true
tljh-config reload

Do you wish to update your shell profile to automatically initialize conda?
This will activate conda on startup and change the command prompt when activated.
If you'd prefer that conda's base environment not be activated on startup,
   run the following command when conda is activated:

conda config --set auto_activate_base false

You can undo this by running `conda init --reverse $SHELL`? [yes|no]
[no] >>> 
You have chosen to not have conda modify your shell scripts at all.
To activate conda's base environment in your current shell session:

eval "$(/home/intrepid-ibex/miniconda3/bin/conda shell.YOUR_SHELL_NAME hook)" 

To install conda's shell functions for easier access, first activate, then:

conda init
