boot2docker和VirtualBox来宾添加如何将/Users装入boot2docker

https://medium.com/boot2docker-lightweight-linux-for-docker/boot2docker-together-with-virtualbox-guest-additions-da1e3ab2465c

tl；dr使用VirtualBox Guest构建自己的自定义boot2docker.iso添加（参见链接）或下载http://static.dockerfiles.io/boot2docker-v1.0.1-virtualbox-guest-additions-v4.3.12.iso并将其保存到~/.boot2docker/boot2docker.iso。

我也需要从容器装载主机目录，我使用了volumemount命令。但在测试过程中注意到，它也在容器内创建文件，但经过一些挖掘发现，它们只是符号链接和主机使用的实际文件系统。

我只是在尝试让我的SailsJS应用程序在Docker容器中运行，以保持我的物理机器清洁。

我正在使用以下命令在/app下装载我的SailsJS/NodeJS应用程序：

cd my_source_code_folder
docker run -it -p 1337:1337 -v $(pwd):/app my_docker/image_with_nodejs_etc

下面是一个Windows路径示例：

docker run -P -it --name organizr --mount src="/c/Users/MyUserName/AppData/Roaming/DockerConfigs/Organizr",dst=/config,type=bind organizrtools/organizr-v2:latest

顺便说一句，在所有这些拉扯头发的过程中，我不得不一次又一次地计算和重新键入路径，我决定编写一个小的AutoHotkey脚本，将Windows路径转换为“Docker Windows”格式的路径。这样，我所要做的就是将任何我想用作装载点的Windows路径复制到剪贴板，按下键盘上的“应用程序键”，它就会将其格式化为Docker喜欢的路径格式。

例如：

将此复制到剪贴板：

C： \Users\My PC\AppData\Roaming\DockerConfigs\Organizr

当光标位于命令行上的所需位置时，按下Apps键，它会将其粘贴在那里：

“/c/Users/My PC/AppData/Roaming/DockerConfigs/Organizr”

为我节省了很多时间。这是给其他可能觉得有用的人的。

; Docker Utility: Convert a Windows Formatted Path to a Docker Formatter Path
;                   Useful for (example) when mounting Windows volumes via the command-line.
;
; By:       J. Scott Elblein
; Version:  1.0
; Date:     2/5/2019
;
; Usage:    Cut or Copy the Windows formatted path to the clipboard, press the AppsKey on your keyboard
;           (usually right next to the Windows Key), it'll format it into a 'docker path' and enter it
;           into the active window. Easy example usage would be to copy your intended volume path via
;           Explorer, place the cursor after the "-v" in your Docker command, press the Apps Key and
;           then it'll place the formatted path onto the line for you.
;
; TODO::    I may or may not add anything to this depending on needs. Some ideas are:
;           
;           - Add a tray menu with the ability to do some things, like just replace the unformatted path
;               on the clipboard with the formatted one rather than enter it automatically.
;           - Add 'smarter' handling so the it first confirms that the clipboard text is even a path in
;               the first place. (would need to be able to handle Win + Mac + Linux)
;           - Add command-line handling so the script doesn't need to always be in the tray, you could
;               just pass the Windows path to the script, have it format it, then paste and close.
;               Also, could have it just check for a path on the clipboard upon script startup, if found
;               do it's job, then exit the script.
;           - Add an 'all-in-one' action, to copy the selected Windows path, and then output the result.
;           - Whatever else comes to mind.
;

#NoEnv
SendMode Input
SetWorkingDir %A_ScriptDir%

AppsKey::

    ; Create a new var, store the current clipboard contents (should be a Windows path)
    NewStr := Clipboard

    ; Rip out the first 2 chars (should be a drive letter and colon) & convert the letter to lowercase
    ; NOTE: I could probably replace the following 3 lines with a regexreplace, but atm I'm lazy and in a rush.
    tmpVar := SubStr(NewStr, 1, 2)
    StringLower, tmpVar, tmpVar

    ; Replace the uppercase drive letter and colon with the lowercase drive letter and colon
    NewStr := StrReplace(NewStr, SubStr(NewStr, 1, 2), tmpVar)

    ; Replace backslashes with forward slashes
    NewStr := StrReplace(NewStr,  "\", "/")

    ; Replace all colons with nothing
    NewStr := StrReplace(NewStr, ":", "")

    ; Remove the last char if it's a trailing forward slash
    NewStr :=  RegExReplace(NewStr, "/$")

    ; Append a leading forward slash if not already there
    if RegExMatch(NewStr, "^/") == 0
        NewStr :=  "/" . NewStr

    ; If there are any spaces in the path ... wrap in double quotes
    if RegExMatch(NewStr, " ") > 0
        NewStr :=  """" . NewStr . """"

    ; Send the result to the active window
    SendInput % NewStr 

[更新]截至2017年6月，Docker for Mac解决了其中所有令人讨厌的部分，您必须使用VirtualBox。它允许您使用/private前缀基本上映射本地主机上的所有内容。更多信息请点击此处。[/UPDATE]

目前所有的答案都是关于Boot2docker的。由于现在不赞成使用docker机器，这适用于docker机器：

首先，ssh到docker机器vm中，并创建要映射到的文件夹：

docker-machine ssh $MACHINE_NAME "sudo mkdir -p \"$VOL_DIR\""

现在将文件夹共享到VirtualBox：

WORKDIR=$(basename "$VOL_DIR")
vboxmanage sharedfolder add "$MACHINE_NAME" --name "$WORKDIR" --hostpath "$VOL_DIR" --transient

最后，再次ssh到docker机器中，并装载刚才共享的文件夹：

docker-machine ssh $MACHINE_NAME "sudo mount -t vboxsf -o uid=\"$U\",gid=\"$G\" \"$WORKDIR\" \"$VOL_DIR\""

注意：对于UID和GID，基本上可以使用任何整数，只要它们还没有使用。

这在OS X El Capitan上从docker机器0.4.1和docker 1.8.3开始测试。

docker run -v /host/directory:/container/directory -t IMAGE-NAME /bin/bash

docker run -v /root/shareData:/home/shareData -t kylemanna/openvpn /bin/bash

在我的系统中，我已经纠正了nhjk的答案，当你添加-t标志时，它就完美无瑕了。
