在Docker容器中运行的Python UDP服务器

在继续开发之前，我想在Docker中测试一个简单的UDP服务器。我以前从未与Docker合作过，所以我认为这应该是初学者的错误

我目前有什么？

服务器

import threading
import socketserver



class ThreadedUDPRequestHandler(socketserver.BaseRequestHandler):

    def handle(self):
        data = self.request[0].strip()
        current_thread = threading.current_thread()
        print("Thread: {} client: {}, wrote: {}".format(current_thread.name, self.client_address, data))
        Split = threading.Thread(target=ParseIncomingData,args=(data,))
        Split.start()



class ThreadedUDPServer(socketserver.ThreadingMixIn, socketserver.UDPServer):
    pass

def publish_messages(data):
    """Publishes multiple messages to a Pub/Sub topic."""
    print('Published {} .'.format(data))

def ParseIncomingData(message):
    sender = threading.Thread(target=publish_messages, args=(message,))
    sender.start()


if __name__ == "__main__":
    HOST, PORT = "0.0.0.0", 6071
    try:
        serverUDP = ThreadedUDPServer((HOST, PORT), ThreadedUDPRequestHandler)
        server_thread_UDP = threading.Thread(target=serverUDP.serve_forever)
        server_thread_UDP.daemon = True
        server_thread_UDP.start()
        serverUDP.serve_forever()
    except (KeyboardInterrupt, SystemExit):
        serverUDP.shutdown()
        serverUDP.server_close()
        exit()

docker文件

# Use an official Python runtime as a base image
FROM python:3.7.2-slim

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
ADD . /app

# Make port 6071 available outside this container
EXPOSE 6071/udp

# Run app.py when the container launches
CMD ["python", "app.py"]

我如何执行容器？

docker run --rm -p 6071:6071/udp listener

我已经尝试过几种有关端口使用情况的组合，但是运行它时却看不到任何东西（Windows）

要测试服务器，我正在使用大力神发送USP数据：
