Why is the Jupyter Lab container not working?#
Jupyter Lab starts as a web server in the container which listens on port 8805.
This port needs to be mapped to a port on the local computer; per default also port 8805 is used.
Mapping fails if the port is used by another service.
To solve this, map to another port when starting the container, e.g.
-p 8806:8805 to map from 8805 in the container to 8806.
