Python waitress windows service

waitress_server.py

# Example class to start a Waitress server as a windows service
# the specific use case is running Waitress as a windows server using pywin32
# The Waitress docs only show how to use waitress-serve, but since waitress-serve is blocking
# you don't get a return value, which makes it impossible to gracefully stop the Waitress server
# from a windows service
# However, looking at the waitress-serve code, it's easy to write a custom class

# example pywin32 windows service: https://gist.github.com/drmalex07/10554232

from waitress.server import create_server
#import your flask app

class WaitressServer:

	def __init__(self, host, port):
		self.server = create_server(flask.app, host=host, port=port)

    # call this method from your service to start the Waitress server
	def run(self):
		self.server.run()

    # call this method from the services stop method
	def stop_service(self):
		self.server.close()
