无法在代理服务器后面下载Docker图像

问题描述：

我在ubuntu 13.10上安装了docker，当我输入我的控制台时：

I installed docker on my ubuntu 13.10 and when I type in my console:

sudo docker pull busybox

我收到以下错误：

Pulling repository busybox
2014/04/16 09:37:07 Get https://index.docker.io/v1/repositories/busybox/images: dial tcp: lookup index.docker.io on 127.0.1.1:53: no answer from server

Docker版本：

$ sudo docker version

Client version: 0.10.0
Client API version: 1.10
Go version (client): go1.2.1
Git commit (client): dc9c28f
Server version: 0.10.0
Server API version: 1.10
Git commit (server): dc9c28f
Go version (server): go1.2.1
Last stable version: 0.10.0

我没有身份验证的代理服务器，这是我的/etc/apt/apt.conf：

I am behind a proxy server with no authentication, this is my /etc/apt/apt.conf:

Acquire::http::proxy "http://192.168.1.1:3128/";
Acquire::https::proxy "https://192.168.1.1:3128/";
Acquire::ftp::proxy "ftp://192.168.1.1:3128/";
Acquire::socks::proxy "socks://192.168.1.1:3128/";

我做错了什么？

答

这是一个老主题，但是如果有人正在寻找建议，我会给我两分钱。

That's an old subject, but I'll give my two cents in case someone else is looking for advice.

这是一个链接到官方docker doc代理http：
https：// docs.docker.com/engine/admin/systemd/#http-proxy

Here is a link to the official docker doc for proxy http: https://docs.docker.com/engine/admin/systemd/#http-proxy

快速大纲：

首先，为docker服务创建一个systemd drop-in目录：

First, create a systemd drop-in directory for the docker service:

mkdir /etc/systemd/system/docker.service.d

现在创建一个名为 / etc / systemd / system / docker.service.d / http-proxy.conf 添加了 HTTP_PROXY 环境变量：

Now create a file called /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable:

[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/"

如果您需要联系内部Docker注册表没有代理，您可以通过 NO_PROXY 环境变量指定它们：

If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY environment variable:

Environment="HTTP_PROXY=http://proxy.example.com:80/"
Environment="NO_PROXY=localhost,127.0.0.0/8,docker-registry.somecorporation.com"

刷新更改：

$ sudo systemctl daemon-reload

验证配置是否已加载：

$ sudo systemctl show --property Environment docker
Environment=HTTP_PROXY=http://proxy.example.com:80/

重新启动Docker：

Restart Docker:

$ sudo systemctl restart docker
