Question

我在Windows 10 pc中运行一个docker容器（运行一个我无法修改网络设置的cloudera映像），我想使用分配的IP（即172.17.0.2）从浏览器连接到它）而不是localhost。有办法吗？怎么样？

（我发现this post，并尝试使用--net = host选项，但分配的docker0 IP仍为172.17.0.1。）

在“ ifconfig”输出下面：

我想您对docker网络有些误解。

Docker使用veth pair作为默认的桥接技术，在主机和容器之间进行通信，请参见下图：

因此，172.17.0.1只是主机的网卡和容器的网卡之间的桥梁，您不能直接使用它。同时，您不应使用主机浏览器中的容器ip来访问它，因为它位于docker设置的专用网络中，您可以使用-p将内部网络服务发布到外部。

而且，当您访问localhost时，它实际上只是访问主机的网络，而docker使用iptables通过docker0网桥将您的网络流量传递到容器的端口。因此，对于您的情况，如果您不想使用localhost，则可以使用主机的IP，在您的情况下为192.168.65.3。

使用IP而不是localhost连接到docker
