docker machine（virtualbox vm）将容器端口导出到主机失败

Question

我正在使用 docker 工具箱进行设置：

1. Windows 10 中的虚拟机默认虚拟机
2. 在 virtualbox vm 中运行的容器

问题是我无法访问容器中的 Web 服务。

这是我使用的一些命令：

# start up the web service
docker run -p 8000:8000 -p 9000:9000 -t -i xxx/myweb /bin/bash -l -c '/root/myweb/demos/web/start-servers.sh'

# terminal print after above cmd
Starting the HTTP TLS server on port 8000
and the Secure WebSocket server on port 9000.

Access the demo through the HTTP server in your browser.
If you're running on the same computer outside of Docker, use https://localhost:8000
If you're running on the same computer with Docker, find the IP
address of the Docker container and use https://<docker-ip>:8000.
If you're running on a remote computer, find the IP address
and use https://<remote-ip>:8000.

WebSocket Server: Logging to '/tmp/openface.websocket.log'

2017-05-27 15:10:13+0000 [-] Log opened.
2017-05-27 15:10:13+0000 [-] WebSocketServerFactory (TLS) starting on 9000
2017-05-27 15:10:13+0000 [-] Starting factory <autobahn.twisted.websocket.WebSocketServerFactory object at 0x7f00ef9f5c90>

现在我尝试使用以下地址访问，但都无法加载网页：

1. 本地主机：8000
2. 192.168.99.100:8000（virtualbox vm的ip）
3. 172.17.0.2:8000（容器的ip）

以下是我使用的一些命令及其结果：

$ docker-machine config
--tlsverify
--tlscacert="C:\\Users\\AIT\\.docker\\machine\\machines\\default\\ca.pem"
--tlscert="C:\\Users\\AIT\\.docker\\machine\\machines\\default\\cert.pem"
--tlskey="C:\\Users\\AIT\\.docker\\machine\\machines\\default\\key.pem"
-H=tcp://192.168.99.100:2376

docker 工具箱也有“默认”虚拟机网络设置的默认配置：

1：NAT

2：仅主机适配器（Virtualbox Host-Only Ethernet Adapter #2）。

我是 docker 工具箱的新手，我应该怎么做才能访问容器中的网页？你能帮我诊断一下我的问题吗？

Answer 1

如果 VM（Docker 主机）正在运行 Linux，请尝试 iptables -F 和 iptables -t nat -F，然后从 Windows 的 Host-Only 或桥接模式网络重试，例如，如果 VM 的 Host Only 接口 IP 为 192.168.56.101，从 Windows 物理主机尝试 IP:8080。

Answer 2

我假设您是在询问有关从运行 Virtualbox 的主机访问 Web 服务的问题。

如您所知，您可以使用 localhost: 或 : 从 boot2docker Linux 机器访问 web 服务。

要从您的主机访问 Web 服务，您可以使用 Virtualbox 提供的端口转发功能。您可以在boot2docker机器的NAT适配器下进入settings->Network->Port forwarding，在boot2docker主机端口和windows机器端口之间添加端口转发。 对于您的示例，您可以说 (hostip=127.0.0.1, host port=8000, guest port=8000)。之后，您可以使用 localhost:8000 或 127.0.0.1.8000 从您的主机访问网络服务器。

希望这会有所帮助。
