Situation:
So I have installed Jupyter-Lab inside a Docker container in a VM on my network. I've then done a commit (I know this isnt the correct way to do things, I should use a Docker file). I then go into the container bash and run jupyter-lab this then output to STDOut the urls to conenct to the WebGUI:

  http://localhost:8888/
  or http://127.0.0.1:8888/

Below is a diagram of my setup:

Problem:
I can't seem to connect to the Jupyter WebGui. I have tried the following commmands:

 sudo docker run -it --rm -p 8888:8888 -v $(realpath ~/notebooks):/tf/notebooks 
 sudo docker run -it --rm -p 8888:8888 --expose 8888 -v $(realpath ~/notebooks):/tf/notebooks 
 sudo docker run -it --rm -p 127.0.0.1:8888:8888 -v $(realpath ~/notebooks):/tf/notebooks 
 sudo docker run -it --rm -p 8888:8888 --ip 0.0.0.0 -v $(realpath ~/notebooks):/tf/notebooks

And I cant seem to connect from my 192.168.10.50 machine to the Jupyter instance. I have run netstat -tulnp which clearly shows that port 8888 is exposed:

docker_machine@instance:~$ netstat -tulpn

This shows that it is listening for any address to conenct so I don't understand.

Question
Why I cant get the Jupyter web interface when I point my browser to 192.168.10.223:8888?

The output of your jupyter-lab suggests that jupyter is only listening on the loopback interface inside the container. To enable access from outside the container you need to bind it to the external interface of the container (or all interfaces).

jupyter-lab --ip="0.0.0.0"
