在OSX上挂载到Docker映像的卷 [英] Mount volume to Docker image on OSX

问题描述

在Mac上，如何将一个卷挂载到Docker容器？

在我的linux框中，这很简单。所有我需要做的就是运行容器时的 -v / src / webapp：/ opt / webapp 。但Mac是不同的，因为我必须运行boot2docker在VirtualBox中运行一个虚拟机。我试过运行

  boot2docker init 
 boot2docker up 
 boot2docker ssh＃to poke around 
 boot2docker stop 
 VBoxManage sharedfolder添加boot2docker-vm--nameUsers--hostpath / Users 
 boot2docker up 
 boot2docker sshsudo modprobe vboxsf
  

但我得到

  modprobe ：module vboxsf在modules.dep中找不到
  

如果我忽略了，仍然尝试挂载在VM上像这样

  boot2docker sshsudo mkdir / test&&sudo mount -t vboxsf Users / test
  

我得到

  mount：mount用户在/ test失败：没有这样的设备
  

我觉得我错过了一些东西非常简单，但我不太清楚。任何帮助将不胜感激。

解决方案

好的，通过一个GitHub PR ，我能够找出一个方法来做到这一点。对于未来的读者来说，这个过程应该在即将发布的boot2docker中得到解决。

 ＃假设boot2docker和VirtualBox已安装
 wget http://static.dockerfiles.io/boot2docker-v1.2.0-virtualbox-guest-additions-v4.3.14.iso 
 mv boot2docker-v1.2.0-virtualbox-guest-added-v4 .3.14.iso〜/ .boot2docker / boot2docker.iso 
＃吹掉你的旧boot2docker-vm（如果存在）（boot2docker down&& boot2docker destroy）
 boot2docker init 
 boot2docker up 
＃根据指示设置DOCKER_HOST 
 boot2docker stop 
 VBoxManage sharedfolder添加boot2docker-vm --name / Users --hostpath / Users 
 boot2docker up 
＃如果你进入VM现在，你会注意到/用户存在，但是是空的;我不知道/关心为什么。 
 boot2docker sshsudo mount -t vboxsf -o uid = 1000，gid = 50 / Users / Users
＃done 
  

这对我有用，所以我希望它适用于其他人。在不久的将来，我希望这个问题可以通过boot2docker来解决，特别是因为我收到这些命令的PR被合并。

编辑：boot2docker 1.3.0支持此操作，无需进一步更改。更新后，我运行这些命令：

  boot2docker destroy＃start over 
 boot2docker download＃下载udpated ISO 
 boot2docker init 
 boot2docker up 
＃done 
  

On a Mac, how do you mount a volume to a Docker container?

On my linux box, this is easy. All I need to do is something like -v /src/webapp:/opt/webapp when running the container. But Mac is different since I have to run boot2docker to run a VM in VirtualBox. I've tried running

boot2docker init
boot2docker up
boot2docker ssh # to poke around
boot2docker stop
VBoxManage sharedfolder add "boot2docker-vm" --name "Users" --hostpath /Users
boot2docker up
boot2docker ssh "sudo modprobe vboxsf"

but I get

modprobe: module vboxsf not found in modules.dep

If I ignore that and still try to mount on the VM like so

boot2docker ssh "sudo mkdir /test && sudo mount -t vboxsf Users /test"

I get

mount: mounting Users on /test failed: No such device

I feel like I'm missing something extremely simple, but I can't quite figure it out. Any help would be greatly appreciated.

解决方案

Ok, after digging through a GitHub PR, I was able to figure out a way to do this. For the future readers out there, this process should be fixed in an upcoming release of boot2docker.

# assuming boot2docker and VirtualBox are installed
wget http://static.dockerfiles.io/boot2docker-v1.2.0-virtualbox-guest-additions-v4.3.14.iso
mv boot2docker-v1.2.0-virtualbox-guest-additions-v4.3.14.iso ~/.boot2docker/boot2docker.iso
# blow away your old boot2docker-vm if it exists (boot2docker down && boot2docker destroy)
boot2docker init
boot2docker up
# set DOCKER_HOST as instructed
boot2docker stop
VBoxManage sharedfolder add boot2docker-vm --name /Users --hostpath /Users
boot2docker up
# if you ssh into the VM now, you'll notice /Users is present, but empty; I don't know/care why.
boot2docker ssh "sudo mount -t vboxsf -o uid=1000,gid=50 /Users /Users"
# done

This worked for me so I hope it works for others. In the near future, I expect this issue to be solved by boot2docker, especially since the PR from which I got these commands was merged.

EDIT: boot2docker 1.3.0 supports this without any further changes. After updating, I ran these commands:

boot2docker destroy  # start over
boot2docker download # download the udpated ISO
boot2docker init
boot2docker up
# done
