无法访问Docker Windows容器内的Internet [英] Not able to access internet inside docker windows container

问题描述

我正在尝试使用docker windows容器构建映像.这是我的dockerfile

I am trying to build an image using docker windows container. Here is my dockerfile

FROM mcr.microsoft.com/windows/servercore:ltsc2019 as installer
RUN Invoke-WebRequest -URI 'www.google.com'

当我运行它时，它无法连接到google.com

When I run this it is failing to connect to google.com

Invoke-WebRequest : The remote name could not be resolved: 'www.google.com'
At line:1 char:73

我在公司网络上工作，我尝试使用设置代理 RUN netsh winhttp set proxy proxy-server="http://proxy.com:80" bypass-list="*.xyz.com" 并导入了注册表HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

I am working on a corporate network and I tried setting proxy using RUN netsh winhttp set proxy proxy-server="http://proxy.com:80" bypass-list="*.xyz.com" and also imported the registry HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

我的容器中的ipconfig/all给出以下结果

ipconfig /all inside my container gives below result

我怀疑存在一些dns/防火墙问题或未正确设置代理.有人可以帮助我确定根本原因并解决此问题.

I suspect there is some dns/firewall issue or not setting proxy in a correct way. Can someone help me in identifying the root cause and fixing this issue.

推荐答案

我遇到了同样的问题，并且能够通过设置DNS来解决它.

I have had the same problem and was able to resolve it setting the DNS.

如果在构建期间进行呼叫，则可以在docker守护进程中进行设置. 在Docker Desktop中，转到设置">"Docker Engine"，然后将以下内容添加到JSON配置中:

If you are making the call during build time you can set it in your docker daemon. In Docker Desktop go to "Settings" > "Docker Engine" and add the following to the JSON config:

"dns": ["1.1.1.1"]

https://docs.docker.com/引擎/参考/命令行/dockerd/#daemon-dns-options

如果在运行时遇到问题，则可以添加dns参数

If you are experiencing the problem during run time you can add the dns argument

--dns 1.1.1.1
