Run Jupyter Lab inside a container

1

I have a lot of containers operating for different services. Since I use Jupyter a lot for school, I’ve decided to build a container for it. Thus, I decided to use a OpenVPN container of my.
The main idea was to connect using VPN and can access Jupyter notebook with tun IP address. The problem is that I can’t access it either way.

Can connect using tun ip: 10.8.0.1, LAN ip: 192.168.0.200 or LXC IP: 10.175.94.11.

I’ve tried nmap and I get all ports closed.

Just follow this GitHub to build my OpenVPN https://gist.github.com/wastrachan/8d75ecf39db1fc25ae73c93989a8df11

$ lxc exec openvpn bash
jupyter-l 564 thales    4u  IPv4 108605      0t0  TCP 127.0.0.1:8888 (LISTEN)

Hi Thales!

Using Jupyter in a LXD container should be quite easy. Here is a tutorial on getting Julia on Jupyter in a LXD container, https://blog.simos.info/how-to-run-julia-on-jupyter-in-a-lxd-container/

The part that I do not understand is why would you need to setup OpenVPN in the container. If you are using a local installation of Jupyter on your desktop/laptop, then you can access easily using a proxy device. See my post above on how to do that. On the other hand, if the installation of Jupyter is at your school, then this is an OpenVPN question on how to setup OpenVPN in a container.

Hello Simos, I want to access it using my iPad, so I need to build a server for it. However, I also need a VPN connection for it. Thats why I’m building it inside the same container. My problem is really specific. I have my Jupiter server running, but I can’t access it.
Maybe there is some filter for my ports and I’m afraid to try and do something wrong with my VPN.

At my tutorial, I explain that Jupyter by default listens on localhost.
Shall I assume that you have looked into that?

edit: Documentation at Jupyter on this, https://jupyter-notebook.readthedocs.io/en/stable/public_server.html

Sorry, shame on me! I’ve carefully read the document. It’s very good by the way. However, I can’t connect connect using tun ip (10.8.0.1).

Using the line bellow:

$ lxc config device add julia port8888 proxy listen=tcp:0.0.0.0:8888 connect=tcp:localhost:8888

and at the host

sudo iptables -t nat -A PREROUTING -p tcp -i enp2s0 --dport 8888 -j DNAT --to-destination 10.175.94.11:8888

I could connect.

With that I can access using the host IP only.

I’m still confusing. Help me please.

To access the Jupyter installation remotely from an OpenVPN connection, you would need to look into OpenVPN routing. See for example, https://openvpn.net/community-resources/setting-up-routing/

At a later point I would suggest to run OpenVPN and Jupyter in separate containers.

I see. So it is better to build another machine for jupyter and access it using host ip? I will follow your suggestion.

One last question. I have a Nextcloud server. Is there a way to integrate it? Like Collabora Office?

EDIT: I’ve created another container.

I setup a service to start jupyter-lab during boot:

$ cat /etc/systemd/system/jupyter.service 
[Unit]
Description=Jupyter Lab

[Service]
Type=simple
PIDFile=/run/jupyter.pid
ExecStart=/usr/local/bin/jupyter-lab --config=/home/ubuntu/.jupyter/jupyter_notebook_config.py
User=ubuntu
Group=ubuntu
WorkingDirectory=/home/ubuntu
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target

However, during boot I have TERMSGN 15.

I feel that I’m missing something.
