Docker/Boot2Docker:为 OS X 上的 docker 设置 HTTP/HTTPS 代理 [英] Docker/Boot2Docker: Set HTTP/HTTPS proxies for docker on OS X

问题描述

简而言之:如何在 Mac OS X 上为 Docker 设置 HTTP/HTTPS 代理?

In short: How can I set the HTTP/HTTPS proxies for Docker on Mac OS X?

详细:

我在 Mac OS X 上通过代理运行 Docker (1.12).我按照安装说明安装了boot2docker.如果我从我的网络内部 Docker 注册表中提取，这工作正常.

I run Docker (1.12) on Mac OS X behind a proxy. I followed the installation instructions and installed boot2docker. This is working fine if I pull from my network-internal Docker registry.

但是，从 docker.io 拉取时出现以下错误:

However, I get the following error when pulling from docker.io:

machine:~ me$ docker run ubuntu echo hello world
Unable to find image 'ubuntu' locally
Pulling repository ubuntu
2014/06/30 13:23:26 Get https://index.docker.io/v1/repositories/ubuntu/images:
dial tcp: lookup index.docker.io: no such host

注意 1:DOCKER_HOST、http_proxy 和 https_proxy 在环境中可用(运行 env 显示所有三个).

Note 1: DOCKER_HOST, http_proxy and https_proxy are available in the environment (running env displays all three).

注意 2:我在其他帖子中读到此错误发生在守护程序未正常运行时.但是，docker version 没有显示任何问题.此外，我可以从我的网络内部 Docker 注册表中拉取和运行映像.

Note 2: I read in other posts that this error occurs when the daemon is not running properly. However, docker version doesn't show any problems. Moreover, I can pull and run images pulled from my network-internal Docker registry.

注意 3:我能够在 Red Hat Linux<上设置 Docker/a> (RHEL).我必须将代理信息添加到 /etc/sysconfig/docker.我读到 Ubuntu 上有一个类似的文件(/etc/init/docker.conf).但是，我在 Mac OS X 上找不到 Docker(或 boot2docker?)的文件.

Note 3: I was able to set up Docker on Red Hat Linux (RHEL). I had to add the proxy information to /etc/sysconfig/docker. I read that there is a similar file on Ubuntu (/etc/init/docker.conf). However, I could not find that file for Docker (or boot2docker?) on Mac OS X.

推荐答案

您需要修改的配置文件不会在您的 OS X 文件系统上，它们将附加到 Tiny Core Linux VM 上，作为您的本地 Docker 服务器.

The config files you need to modify won't be on your OS X file system, they'll be attached to the Tiny Core Linux VM which acts as your local Docker server.

要为此配置代理，首先从应用程序启动 Boot2docker.启动后，获取一个终端窗口并通过 ssh 进入 VM:

To configure the proxy for that, first start Boot2docker from Applications. Once it's started, get a terminal window and ssh into the VM:

bash-3.2$ boot2docker ssh
Warning: Permanently added '[localhost]:2022' (RSA) to the list of known hosts.
                        ##        .
                  ## ## ##       ==
               ## ## ## ##      ===
           /""""""""""""""""\___/ ===
      ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ /  ===- ~~~
           \______ o          __/
                         __/

boot2docker: 1.0.1
             master : cad5ece - Fri Jun 20 02:03:40 UTC 2014
docker@boot2docker:~$

现在创建/修改/var/lib/boot2docker/profile 来设置代理信息:

Now create/modify /var/lib/boot2docker/profile to set proxy info:

docker@boot2docker:~$ sudo vi /var/lib/boot2docker/profile 

Tinycore 需要代理信息如下:protocol://ip:port
为安全起见，我为 HTTP 和 HTTPS 设置了代理.

Tinycore needs the proxy info as follows: protocol://ip:port
To be safe I set proxies for both HTTP and HTTPS.

export HTTP_PROXY=http://your.proxy.name:8080
export HTTPS_PROXY=http://your.proxy.name:8080

现在您可以重新启动 VM docker 服务并退出 VM.

Now you can restart the VM docker service and exit the VM.

docker@boot2docker:~$ sudo /etc/init.d/docker restart
docker@boot2docker:~$ exit
Connection to localhost closed.

您现在应该能够针对 VM 实例运行客户端.

You should be able to run the client against the VM instance now.

bash-3.2$ docker search ubuntu
NAME                                             DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED
ubuntu                                           Official Ubuntu base image                      356

此更改通过 VM 重新启动保持不变.你应该只需要做一次.

This change is persisted through VM restarts. You should only need to do it once.

作为记录，VirtualBox 有一个全局的代理首选项设置，但我在那里尝试的任何方法都不起作用.

For the record, VirtualBox has a global preference setting for proxies but nothing I tried there would work.
