Docker外部文件访问不在OSX中的/ Users /中 [英] Docker External File Access Not in /Users/ on OSX

问题描述

所以，尽管 Docker 1.3现在允许通过boot2docker轻松访问OSX上的外部存储，用于/ Users / 中的文件，我仍然需要访问不在/ Users /中的文件。我有一个设置文件在/ etc / settings /我想让我的容器访问。另外，我的容器中的CMD将日志写入容器中的/ var / log，我宁愿把它写入主机上的/ var / log。我一直在玩 VOLUME ，并在运行时传递东西与 -v ，但我没有得到任何地方。谷歌没有太多的帮助。有人可以帮助吗？

So, despite Docker 1.3 now allowing easy access to external storage on OSX through boot2docker for files in /Users/, I still need to access files not in /Users/. I have a settings file in /etc/settings/ that I'd like my container to have access to. Also, the CMD in my container writes logs to /var/log in the container, which I'd rather have it write to /var/log on the host. I've been playing around with VOLUME and passing stuff in with -v at run, but I'm not getting anywhere. Googling hasn't been much help. Can someone who has this working provide help?

推荐答案

如boot2docker现在包括VirtualBox Guest添加，现在可以使用客户机操作系统（boot2docker-vm）在主机（OSX）上共享文件夹。 / Users /自动挂载，但您可以挂载/共享自定义文件夹。在您的主机控制台（OSX）中：

As boot2docker now includes VirtualBox Guest Additions, you can now share folders on the host computer (OSX) with guest operating systems (boot2docker-vm). /Users/ is automatically mounted but you can mount/share custom folders. In your host console (OSX) :

 $ vboxmanage sharedfolder add "boot2docker-vm" --name settings-share --hostpath  /etc/settings --automount

启动boot2docker和ssh（ $ boot2docker up / $ boot2docker ssh ）。
选择要在boot2docker VM中安装settings-share（/ etc / settings）的位置：

Start boot2docker and ssh into it ($boot2docker up / $boot2docker ssh). Choose where you want to mount the "settings-share" (/etc/settings) in the boot2docker VM :

$ sudo mkdir /settings-share-on-guest
$ sudo mount -t vboxsf settings-share /settings-share-on-guest

根据 / settings 是在docker容器中声明的卷add -v / settings-share -on-guest：/ settings 到docker运行命令到挂载主机目录设置 - 作为数据卷共享。

According that /settings is the volume declared in the docker container add -v /settings-share-on-guest:/settings to the docker run command to mount the host directory settings-share-on-guest as a data volume.

适用于Windows ，没有在OSX上测试但应该工作。

Works on Windows, not tested on OSX but should work.
