如何从 Windows 10 上的容器连接到 docker 主机(Docker for Windows) [英] How to connect to docker host from container on Windows 10 (Docker for Windows)

问题描述

docker 容器可以通过哪个 IP 地址连接到 Docker for Windows 上的主机(在 Windows 10 上)?你如何找到这个IP地址?

At which IP address can a docker container connect to its host on Docker for Windows (on Windows 10)? How do you find this IP address?

示例:您在 Windows 10 计算机上的端口 1234 上运行了一项服务.容器内的程序必须访问此服务.程序应该使用什么 IP 地址连接到主机?

Example: you have a service running at port 1234 on your Windows 10 machine. A program inside your container must access this service. What IP address should the program use to connect to the host?

推荐答案

简短回答:在大多数情况下，您需要 10.0.75.1.

Short answer: in most cases, you'll need 10.0.75.1 .

在 Docker for Windows 中，容器通过称为 DockerNAT 的 vEthernet 适配器进行通信.要查找其详细信息，请打开命令提示符并键入

In Docker for Windows, the container communicates through a vEthernet adapter called DockerNAT. To find its details, open Command Prompt and type

ipconfig

查找类似于

Ethernet adapter vEthernet (DockerNAT):

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::fd29:297:4583:3ad4%4
   IPv4 Address. . . . . . . . . . . : 10.0.75.1
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . :

IPv4 Address右边的IP地址就是你需要的.

The IP address to the right of IPv4 Address is the one you need.

注意:确保服务允许来自主机外部的连接.就该服务而言，您的 docker 容器是一台不同的机器.还要确保 Windows 防火墙允许与服务进行通信.

Note: make sure the service allows connections from outside your host. As far as that service is concerned, your docker container is a different machine. Also make sure Windows Firewall allows communication to and from the service.
