Question

我只是没有足够的网络知识来理解这一点。

在笔记本电脑上，我同时运行Docker和多个无用的VM。

我想从docker容器中连接到其中一个无用的VM，但是ping仍然挂起或吐出“ Destination Host Unreachable”。我可以从主机（例如，在容器外部）对无用的VM进行ping操作。

您能指出正确的方向吗？我基本上想在无业游民的VM上安装Nginx，但在Docker中有一些负载均衡器。

这意味着docker容器需要能够“查看”无业游民的VM。

我需要一个路由表条目吗？我需要特殊的网络适配器吗？我需要建立一座桥梁吗？我只是不够了解，不胜感激朝着正确的方向前进。

以下是容器中的详细信息：

这是来自无业游民的VM的一些东西：

当我从docker容器ping 172.17.8.101（我要ping的无用VM的IP）时，它只是挂起。如何从一个Docker容器访问其中一个VM？

如何在Docker容器中调试``无主机路由''
