Using `waitress` to serve a Django app on multiple ports

Question

I'm using waitress to serve my Django app. I need it to serve the app on two ports simultaneously, in the same thread. (Can't be on a separate process because I need to be able to run it in my debugger in development.)

How can I do that?

Let your reverse proxy serve the content from a different port. — enthus1ast, Jun 03 '15 at 12:17

The latest version of waitress is now able to listen on multiple sockets, including IPv4 and IPv6.

Instead of passing in a host/port combination you now provide waitress with a space delineated list, and it will create as many sockets as required.

from waitress import serve
serve(wsgiapp, listen='0.0.0.0:8080 [::]:9090 *:6543')

If you use a configuration file, replace the "host" and "port" entries in [server:main] with "listen". – Georg Pfolz May 03 '20 at 05:04

I've never used waitress, but the latest documentation doesn't seem to mention using multiple ports. A quick clone and ack for 'port' and 'socket' through the code helped me find runner.py with documented command-line options, and the option --port=PORT doesn't seem to support multiple ports. That's not proof, but a good indication without digging too deep.

If I were to take a stab at adding this feature to waitress, then it sounds like select is what's needed.

Here's a StackOverflow example that uses select to bind a basic server to multiple ports.
