Cherrypy - Running natively in OS3

[jfmatth]

I have tried unsuccessfully to run CherrPy natively in OS3, as it's own server (i.e. no gunicorn or WSGI server).

Any help is appreciated

app.py

import cherrypy

class Root(object):
    @cherrypy.expose
    def index(self):
        return "Hello World!"
if __name__ == '__main__':
    from cherrypy._cpnative_server import CPHTTPServer
    cherrypy.server.httpserver = CPHTTPServer(cherrypy.server)
    cherrypy.server.socket_host = "0.0.0.0"
    cherrypy.quickstart(Root(), '/')

@GrahamDumpleton any experience here?

I think it will be caused by docker's handling sockets and cherrypy no happy about that way. Since when I exec into the container, it works:

# docker exec -ti `docker ps -q` bash
$> curl 127.0.0.1:8080
Hello World!

But on the host I also see:

curl: (56) Recv failure: Connection reset by peer

Example at:

• https://gitlab.com/osevg/python-cherrypy-engine

works fine.

It may be related to whatever:

    from cherrypy._cpnative_server import CPHTTPServer
    cherrypy.server.httpserver = CPHTTPServer(cherrypy.server)

is doing, which basic examples of using CherryPy do not use.
