docker - 使用 Cisco VPN AnyConnect 时无法让 docker-machine 与 virtualbox 一起使用

Question

当我使用 Cisco VPN Anyconnect 加入我的公司网络时，我无法让 docker-machine 连接到我的 virtualbox 虚拟机。这与 Cisco Anyconnect 接管所有 192.168.. 路由有关。我还尝试使用完全不同的 cidr 范围(25.0.1.100/24)，但仍然无法让 docker-machine 与 VM 对话。当我检查路由表时，路由被添加到 utun0 而不是 vboxnet0。我假设 utun0 是 VPN 的主机网络接口(interface)。这里是 docker-machine 输出:

docker-machine create -d virtualbox dev

WARNING >>> 
This machine has been allocated an IP address, but Docker Machine could not
reach it successfully.

SSH for the machine should still work, but connecting to exposed ports, such as
the Docker daemon port (usually <ip>:2376), may not work properly.

You may need to add the route manually, or use another related workaround.

This could be due to a VPN, proxy, or host file configuration issue.

You also might want to clear any VirtualBox host only interfaces you are not using.
To see how to connect Docker to this machine, run: docker-machine env dev

我在 192.168.x.x 上遇到了类似的 IP 冲突问题，我通过更改 VirtualBox 仅主机网络的子网解决了它。

1) 运行 docker-machine rm dev

2) 进入 VirtualBox 首选项并删除仅主机网络

3) 运行 docker-machine create --driver virtualbox --virtualbox-hostonly-cidr "25.0.1.100/24"dev
