Mysql Docker集装箱（MariaDb、AspNet）可以'；不能在网络上通信

我已经设置了一个Docker Compose文件，它创建了一个mariadb数据库和一个aspnet后端（这两个文件都来自我编写的Docker文件）。如果我在compose之外公开端口并运行容器（使用localhost），或者在docker compose文件中设置network_模式：“host”，那么应用程序将按预期进行交互。但是，使用compose在容器之间生成任何命令的默认网桥网络似乎超时

我尝试运行连接到同一网络的网络容器（nicolaka/netshoot），并通过DNS名称ping相关容器。名称解析为IP地址，然后ping挂起。我还运行并连接了一个mysql容器，并尝试连接到mariadb容器，结果导致超时

这一切看起来都是我的设置中的一些网络问题。下面列出的配置，任何帮助都将不胜感激

再次感谢您的帮助

所以我似乎已经解决了这个问题。原来是操作系统（Arch Linux）而不是docker的问题，我通过在Windows系统上运行相同的文件发现了这一点

对于任何arch用户，我已在
