Support for AI Platform Notebooks

[gogasca]

AI Platform Notebooks are accessible via Inverse Proxy.

Inverse Proxy only support backend on JupyterLab port 8080.
This plugin is launching a new web server in a random port, hence when we install it, and try to display GPU information just a blank screen is displayed, as Proxy cant route back the requests on this new web server.

Questions:

1. Can you support rendering the details inside JupyterLab without launching a new webserver?
2. If ImportError for README instructions #1 is not possible, can you add support for a URL can be used which will be used to render the contents.
3. I'm able to start ngrok on this random port and access the local URL. I would like to be able to provide this URL to extension and when I click in extension content is rendered.

ngrok generates a public URL: https://9d4232d76b1b.ngrok.io/

Flow:

• Extension will allow me to configure a public URL: https://9d4232d76b1b.ngrok.io
• When I click on GPU-memory it will render: and it will just access URL + resource. Example: https://9d4232d76b1b.ngrok.io/GPU-Memory, etc.

Thanks for raising this.

This extension uses the jupyter-server-proxy library to reverse proxy traffic via Jupyter Lab. So it shouldn't matter what port the extension is running on behind the scenes because everything is exposed via the Jupyter port.

If the dashboard is not displaying correctly this could be an issue with the way the URL is being constructed.

Could you please share a minimal reproducible example so we can check this out?

Hi Jacob, thanks for responding,

These are the steps to reproduce:

1. Create an AI Platform Notebooks in Google Cloud.
2. Install NVIDIA plugin

Login via SSH to Notebooks and enter the following commands:

pip install jupyterlab-nvdashboard
jupyter labextension install jupyterlab-nvdashboard
jupyter lab build
service jupyter restart (or reboot)

3. Restart Jupyter
4. Access JupyterLab URL. (URL that Notebooks generate is something like this: https://XXXXXXXXXXX-dot-us-west1.notebooks.googleusercontent.com/lab) this URL provides access to VM and its behind an Inverse Proxy
   Browser <----> [Google Cloud Inverse Proxy] <------> [ Proxy Agent <-----> JupyterLab ]

• Google Cloud Inverse Proxy sits inside Google infrastructure
• Proxy Agent is a docker container running inside the Notebook

5. Access GPU Dashboards (Buttons are displayed but when I clicked on them I get a blank page)
6. Logs

[jacobtomlinson]

Many thanks @gogasca.

Its appears that the websocket connection is successful, but Bokeh isn't happy about something.

bokeh.protocol.exceptions.ProtocolError: Subprotocol header is not 'bokeh'

I expect some critical header is being rewritten somewhere during the multiple layers of proxies.

It appears this issue came up once in the jupyter-server-proxy and was fixed by correctly proxying subprotocols. I wonder if those subprotocols are not being proxied by Google Cloud Inverse Proxy.

Is this something you are able to investigate?

[gogasca]

Yes, I should be able to run a local proxy version and test. Proxy do not support websockets but it does have a shim to enable support. https://github.com/google/inverting-proxy/blob/a121408eb881af9e75b10064b46258c4ab12c47f/agent/websockets/shim.go#L41

I will test and get back to you. Thanks

[eriknil-onehot]

@gogasca did you have any luck with this? I'm experiencing the same issue myself.
