通过终端获取Docker for Mac代理变量 [英] Getting Docker for mac proxy variables through terminal

问题描述

我在代理后面使用Docker for mac。我在Docker GUI的代理->手动代理配置下设置了代理配置。这样一来，我就可以从代理后面的存储库中下载Docker映像。

I am using Docker for mac behind a proxy. I set up the proxy configuration in the Docker GUI under "Proxies" -> "Manual proxy configuration". This lets me download Docker images from the repository behind the proxy.

接下来，我设置 http_proxy 和 https_proxy 环境变量，我在docker-compose.yml中使用它们将它们传递给构建：

Next, I set the http_proxy and https_proxy environment variables and I use them in my docker-compose.yml to pass them to the build:

services:
  app:
    build:
      context: .
      args:
        http_proxy: $http_proxy
        https_proxy: $https_proxy

如何获取通过终端中的Docker GUI设置的变量，而不必两次设置？我可以使用任何特定于Docker的环境变量吗？

How can I get the variables that I set through the Docker GUI in the terminal so I don't have to set them twice? Are there any Docker-specific environment variables that I can use?

推荐答案

如果我正确理解了您想要的，那么您只需要读取 docker info 给出的内容：

If I understood correctly want you want, then you just need to read what's given by docker info:

❯ docker info | grep Proxy
Http Proxy: http://localhost:3128
Https Proxy: http://localhost:3128

如果在GUI中设置了这两个，它们将出现在输出的结尾附近。如果未设置，则不会，在我的情况下，没有代理：* .local，169.254 / 16 将会出现。

If these two are set in the GUI, they will appear near the end of the output. If they are not set, they won't, and in my case, No Proxy: *.local, 169.254/16 will appear instead.
