[FIXED] Why is there not a "global" link showing when starting a jupyter notebook inside a docker container

Issue

I want to use acces a jupter notebook which is running in a debian server using docker containers thru my local machine. The problem I face is that I expect a link with a token which I can insert in my browser on my local machine, but unfortunately this isn't the case.

When I start the jupyter notebook with the configs:

CMD ["python", "-m", "jupyterlab", "--port=8888", "--no-browser", "--ip=0.0.0.0", "--allow-root", "-NotebookApp.token=''", "--NotebookApp.password=''", "examples/notebooks"] 

A link like this comes out http://<ip_adress>/lab, but I expect something like this http://<ip_adress>/lab/?token=

Does anyone know how to fix this?

P.S. I've read and tried all the answers from this thread Access Jupyter notebook running on Docker container

Solution

You're not seeing a token because you've set -NotebookApp.token=''.

In combination with -NotebookApp.password='' you have completely disabled security (see the docs). These means you can access JupyterLab at http://localhost:8888 without requiring any password or token.

If this is not the behavior you want, don't explicitly disable the security features.
