从Docker容器发送udp广播

本文介绍了从Docker容器发送udp广播的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有几个Docker容器（使用 docker-compose 和一个网络-network-sol）

I'm having a few docker containers (Using docker-compose and a single network - network-sol)

其中一个容器是 Spring Boot应用程序，该应用程序将UDP广播发送到本地网络。 255.255.255.255失败，因为它是 network-sol

One of the containers is a Spring Boot application that sends UDP broadcast to the local network. 255.255.255.255 fails because It's the local broadcast address of network-sol

的本地广播地址如何广播UDP消息，例如顶级本地网络会得到那些数据包？我是否必须使用定向广播地址？

How can I broadcast UDP messages such as the "top local network" Will get those packets? Do i have to use directed broadcast address for that?

PS

如果应用程序部署在docker（本地网络的一部分）之外，则广播工作>

broadcast works if the application is deployed outside of docker (part of the local network

推荐答案

您应该运行 docker-compose.yml 文件中定义的服务使用 network_mode：主机。

You should either run the service defined in your docker-compose.yml file with network_mode: host.

或者，您可以通过发布要与之通信的容器的端口来发布它使用以下配置。请注意，< / udp 是UDP通信正常工作所必需的。

Alternatively you can publish the port of the container you intended to communicate with by publishing it using the following configuration. Note that the /udp is required for UDP communication to work.

service: ports: - "8080:8080/udp"
