Windows 10代理上的Docker无法传播到容器 [英] Docker at Windows 10 proxy propagation to containers not working

问题描述

我落后于合作代理并在Windows 10上运行docker。我已经根据

我能够提取图像，但是这些代理设置没有传播到容器，例如当我运行alpine env时，它不显示proxy conf。下面是我的输出

 λdocker run alpine env 
 PATH = / usr / local / sbin：/ usr / local / bin：/ usr / sbin：/ usr / bin：/ sbin：/ bin 
 HOSTNAME = 14fca5bee12f 
 HOME = / root 
  

以下是根据文档所述的预期输出。

在构建以下docker文件时，我从高山容器中收到连接错误

Docker版本

  Docker版本17.12.0-ce，构建c97c6d6 
  

DockerFile

  FROM alpine：latest 
添加HelloWorld.class HelloWorld.class 
 RUN apk --update add openjdk8-jre 
 ENTRYPOI NT [ java， -Djava.security.egd = file：/ dev /./ urandom， HelloWorld] 
  

错误

将代理作为build-arg传递

我尝试了以下命令，它起作用了。还有其他方法可以自动传播代理文档中所述的代理设置（请参见上面的链接）

  docker build --tag docker-hello-world：latest。 --build-arg http_proxy = http：//< username>：<密码> @proxy_address：proxy_port / --build-arg https_proxy = http：//< username>：<密码> @proxy_address：proxy_port / --build-arg no_proxy = localhost，127.0.0.1 
  

解决方案

我有同样的问题。拉取映像有效，但置备容器无效。在这种情况下，解决方案是为Docker提供名为〜/ .docker / config.json 的配置文件，其中包含以下内容。

  {
代理：
 {
默认：
 {
 httpProxy： http：//proxy.server....com：8080，
 httpsProxy： https：//proxy.server.....com：8080 
} 
 } 
} 
  

我希望这可以解决您的问题。

I am behind cooperate proxy and running docker on windows 10. I have setup the proxy on docker as per the documentation here.

I am able to pull images but these proxy settings are not propagating to containers e.g. when I run alpine env, it does not show proxy conf. Below is my output

λ docker run alpine env                                          
  PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
  HOSTNAME=14fca5bee12f                                            
  HOME=/root                                                       

Following is the expected output as per the documentation.

On building following docker file, I get connection errors from alpine container

Docker Version

The command '/bin/sh -c apk --update add openjdk8-jre' returned a non-zero code: 1                                

Passing Proxy as build-arg

I tried the following command and it worked. Is there any other way to automatically propagate the proxy settings as mentioned in documentation (see link above)

docker build --tag "docker-hello-world:latest" . --build-arg http_proxy=http://<username>:<password>@proxy_address:proxy_port/ --build-arg https_proxy=http://<username>:<password>@proxy_address:proxy_port/ --build-arg no_proxy=localhost,127.0.0.1

解决方案

I had the same problem. Pulling images was working but provisioning a container was not working. In this case the solution was to provide Docker with a configuration file named ~/.docker/config.json with the following contents.

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://proxy.server....com:8080",
     "httpsProxy": "https://proxy.server.....com:8080"
   }
 }
}

I hope this will solve your problem.
