通过远程访问API访问Docker for Mac [英] Accessing Docker for Mac via Remote Access API

问题描述

最近我一直在尝试使用Docker，我希望能够从一个容器内访问Docker，以便运行更多的容器。当我正在尝试平台时，我在Mac上本地运行它，而且我不确定如何启用Docker守护进程从容器内部访问。

为了在本地访问守护程序，我使用UNIX套接字 /var/run/docker.sock ，但UNIX套接字无法联网，所以我发现一篇文章解释了如何在Ubuntu上启用Docker Remote Access REST API（ http://www.virtuallyghetto.com/2014/07/quick-tip-how-to-enable-docker-remote-api.html ）。它解释了我需要如何将 DOCKER_OPTS =' - H tcp：//0.0.0.0：4243 -H unix：///var/run/docker.sock'文件 /etc/init/docker.conf ，但是我无法在我的Mac上找到这个文件。

任何帮助或指示将不胜感激，

干杯

p>您需要设置一个 DOCKER_HOST 环境变量：

  export DOCKER_HOST =' -  H unix： ///var/run/docker.sock -H tcp：// localhost：2376'
  

你可以在〜/ Library / LaunchAgents / 中在系统启动时创建一个 environment.plist 文件：

 <？xml version =1.0encoding =UTF-8？> 
<！DOCTYPE plist PUBLIC -  // Apple // DTD PLIST 1.0 // ENhttp://www.apple.com/DTDs/PropertyList-1.0.dtd\"> 
< plist version =1.0> 
< dict> 
< key> Label< / key> 
< string> my.startup< / string> 
< key> ProgramArguments< / key> 
< array> 
< string> sh< / string> 
< string> -c< / string> 
< string> 
 launchctl setenv DOCKER_HOST -H unix：///var/run/docker.sock -H tcp：// localhost：2376 
< / string> 
< / array> 
< key> RunAtLoad< / key> 
< true /> 
< / dict> 
< / plist> 
  

I've been recently experimenting with Docker and I would like to be able to access Docker from within a container in order to run more containers. As I'm experimenting with the platform, I'm running it locally on my Mac, and I am unsure how I would enable the Docker Daemon to be accessed from inside a container.

In order to access the daemon locally, I use the UNIX socket /var/run/docker.sock, however UNIX sockets are not able to be networked, and so I found an article explaining how to enable the Docker Remote Access REST API on Ubuntu (http://www.virtuallyghetto.com/2014/07/quick-tip-how-to-enable-docker-remote-api.html). It explained how I needed to append DOCKER_OPTS='-H tcp://0.0.0.0:4243 -H unix:///var/run/docker.sock' to the file /etc/init/docker.conf, however I have been unable to find this file on my Mac.

Any help or directions would be greatly appreciated,

Cheers

You need to set a DOCKER_HOST environment variable:

export DOCKER_HOST='-H unix:///var/run/docker.sock -H tcp://localhost:2376'

You can create a environment.plist file in ~/Library/LaunchAgents/ to do that at system startup:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>my.startup</string>
  <key>ProgramArguments</key>
  <array>
    <string>sh</string>
    <string>-c</string>
    <string>
launchctl setenv DOCKER_HOST -H unix:///var/run/docker.sock -H tcp://localhost:2376
    </string>
  </array>
  <key>RunAtLoad</key>
  <true/>
</dict>
</plist>
