在OSX上手动共享目录作为Docker卷安装点 [英] Manually sharing directory as docker volume mounting point on OSX

问题描述

根据这个从Docker网站的教程，当您启动一个容器时，它将自动共享您的 / Users / username 。

我当前的问题：

但在我的学校，我的 $ HOME 不在 / Users ，当我尝试直接在我的容器上装载这样的东西，如 docker run -d -P -v $ HOME / site：/ usr / share / nginx / html --name mysite nginx （像链接中的教程），我无法通过挂载的卷更改文件。所以我想我的 $ HOME 不会自动共享。

但是，如果我运行 docker stpect mysite 我得到：

 HostConfig：{
绑定 [
/ nfs / zfs-student-3 / users / vmonteco / site：/ usr / share / nginx / html
]，
  

和

 挂载：[
 { 
源：/ nfs / zfs-student-3 / users / vmonteco / site，
目的地：/ usr / share / nginx / html，
 ：，
RW：true，
传播：rprivate
} 
  

我的问题只是这样：

我如何手动共享虚拟机托管坞站（virtualbox here）到目录使用它作为音量安装点？

这是我在不推荐使用Boot2docker之前做的：

使用 boot2docker ，我可以运行如下：

  SHAREDIR = $ HOME / share 
＃创建共享文件夹。 
 mkdir $ SHAREDIR 
 
＃mount共享文件夹，同时重新启动boot2docker：
 boot2docker --vbox-share =$ SHAREDIR = shareup 
 echo创建和安装boot2docker VM中的\share\目录。 
 boot2docker sshsudo mkdir / share; sudo mount -t vboxsf share / share
 
＃运行容器：
 docker run -ti --rm -v / share： / share -v / Users：/ Users base / archlinux sh 
  

它工作正常。 >

但是现在， boot2docker 是已弃用，我没有找到如何使用虚拟机我现在必须使用它使用virtualbox）。

如果我理解的很好，它应该像boot2docker一样工作：

  1 2 
 [来自OSX的目录]< ===> [VM目录（VM替换Boot2docker）]< ===> [容器目录] 
  

如果我仍然很了解，现在唯一不起作用的是 [1] ，这是由我刚刚与boot2docker共享的小脚本的中间部分处理。

但是现在该怎么办？ / p>

总结：
开始docker 1.8可以通过vbox cli添加目录。

  VBoxManage共享文件夹添加<机器名/ id> --name< mount_name> --hostpath< host_dir> --automount 
  

According to this tutorial from docker website, When you start a container it automatically shares your /Users/username.

My current problem :

But in my school my $HOME isn't in /Users, and when I try to directly mount volumes on my container with something like docker run -d -P -v $HOME/site:/usr/share/nginx/html --name mysite nginx (like the tutorial from the link), I can't change files through the mounted volume. So I guess my $HOME isn't automatically shared.

But if I run docker instpect mysite I get :

"HostConfig": {
    "Binds": [
        "/nfs/zfs-student-3/users/vmonteco/site:/usr/share/nginx/html"
    ],

and

"Mounts": [
    {
        "Source": "/nfs/zfs-student-3/users/vmonteco/site",
        "Destination": "/usr/share/nginx/html",
        "Mode": "",
        "RW": true,
        "Propagation": "rprivate"
    } 

My question is simply this :

How could I manually share directories with the VM hosting docker (virtualbox here) to use it as volume mounting points?

This is how I did it with Boot2docker before it was deprecated :

With boot2docker I could have run something like :

SHAREDIR=$HOME/share
# creating share folder.
mkdir $SHAREDIR

# mount shared folder while relaunching boot2docker :
boot2docker --vbox-share="$SHAREDIR=share" up
echo "Creating and mounting \"share\" directory in boot2docker VM."
boot2docker ssh "sudo mkdir /share; sudo mount -t vboxsf share /share"

# running the container :
docker run  -ti --rm -v /share:/share -v /Users:/Users base/archlinux sh

And it worked fine.

But now boot2docker is deprecated and I didn't find how to do this with the VM I have to use now (it uses virtualbox).

If I understand well, it should work the same way as boot2docker worked :

                       1                                                  2
[directory from OSX] <===> [VM directory (the VM replaces Boot2docker)] <===> [container directory]

If I still understand well the only that doesn't work now is the point [1], this was handled by the middle part of the little script I just shared with boot2docker.

But how could I do now?

See this answer: https://stackoverflow.com/a/32030385/2434234

In summary: Starting in docker 1.8 you can add directories through the vbox cli.

VBoxManage sharedfolder add <machine name/id> --name <mount_name> --hostpath <host_dir> --automount
