Bokeh Server not showing up in jupyterlab in a docker container

Community Supportserver

I am trying to get a bokeh server to run in a jupyter notebook in jupyter lab (I’m specifically interested in using python callbacks in the notebook, so if there is another way to do that, feel free to chime in), which is running in a docker container on os X.

When I try and use the example ‘notebook_embed.ipynb’, I get no output after running the notebook, other than the ‘BokehJS 2.3.1 successfully loaded.’ text when running ‘output_notebook’.

I have changed the show command to: show(bkapp, notebook_url="http://localhost:52947"), which is the port and host that my jupyter notebook is accessed at. I have also tried show(bkapp, notebook_url="http://localhost:8888") which is the internal port that jupyterlab is hosting it at.

I’m not sure how to debug this… anyone have any ideas?

Ok, Some more information:

In the Javascript console, I’m getting this error when I run the cell that has the show(bkapp, notebook_url="http://localhost:8888/"):

Which is showing a bunch of random ports on localhost that are being tried in order to connect. If I understand this correctly, the cell is trying to call out to a bokeh server on the docker container, but it can’t reach because the correct port isn’t being forwarded.

How do I get the bokeh server to choose a single port? (I can then open up that port on the docker container to make this work).

@spott You should be able to pass a port keyword argument to show to fix the port that the Bokeh server instance listens on. By default it uses port=0 which picks a random open port. Note that fixing a port means that running the show a second time will certainly fail (the port will still be in use).

I apologize, I missed that I got responses here.

I tried the port thing, but I’m getting these errors now:
