Run multiple Bokeh servers

I have multiple Python scripts to create Bokeh apps on different ports.

Currently, I start each server individually from command line using bokeh serve

What is the easiest way to run multiple Bokeh servers on different ports ideally by running a single Python script?

Is it possible to set the permitted clients individually for each server?

A bash solution would be simpler, but if you really need a Python one then here it is:

import shlex
from multiprocessing import Process

from bokeh.command.bootstrap import main

argss = ['--port 57878 --allow-websocket-origin localhost:57878 test.py',
         '--port 58989 --allow-websocket-origin localhost:58989 test.py']

processes = [Process(target=main, args=(['python', 'serve'] + shlex.split(args),)) for args in argss]
for p in processes:
    p.start()
for p in processes:
    p.join()

Just adapt the argss list to your needs.

Note that bokeh.command.boostrap is not a public API - it may easily change in any future version. To prevent breakage, you can use the subprocess module to instead start proper bokeh serve commands.
