Serving interactive bokeh figure on heroku

Question

I\'m trying to serve an interactive bokeh figure via heroku. The figure I\'m trying to have served is essentially equivalent to this one (example, code). I\'m

Answer 1

I'm just going to answer my own question since I was eventually able to get this to work and nobody else has answered it yet.

I ended up with a Procfile that looked like this:

web: bokeh serve --port=$PORT --host=myapp.herokuapp.com --host=* \
     --address=0.0.0.0 --use-xheaders myapp.py

a bit of background on what all of these arguments mean (as far as I can tell):

--port: specifies the port that the bokeh server will listen on, $PORT is set by heroku

--host=myapp.herokuapp.com and --host=*: specify the host name as myapp.heroku..., the wildcard is supposed to allow all hosts to be accepted. I'm not sure this in needed anymore.

--address=0.0.0.0: I think this tells bokeh to figure out on its own, which IP address it will be on.

--use-xheaders: causes bokeh to override the remote IP and URI scheme/protocol

I'm happy to make edits to this or accept a more knowledgeable users answer if there are issues with this approach.

Answer 2

The accepted answer didn't work for me as written (likely due to a bokeh version difference), but since this is still one of the top hits for this question, here is my minor modification that did work:

web: bokeh serve --port=$PORT --num-procs=0 --allow-websocket-origin=myapp.herokuapp.com --address=0.0.0.0 --use-xheaders myapp.py
