我正在尝试将主机目录装载到Docker容器中,以便在主机上完成的任何更新都反映到Docker集装箱中。

我哪里做错了什么。以下是我所做的:

kishore$ cat Dockerfile

FROM ubuntu:trusty
RUN apt-get update
RUN apt-get -y install git curl vim
CMD ["/bin/bash"]
WORKDIR /test_container
VOLUME ["/test_container"]

kishore$树.├── Dockerfile文件└── 主文件夹├── tfile1.text├── tfile2.txt文件├── tfile3.txt文件└── tfile4.txt文件

1个目录,5个文件基肖尔$pwd/用户/kishore/tdockkishore$docker build--tag=k3_s3:最新。

我不知道如何检查boot2docker版本

问题和面临的问题:

如何将main_folder链接到docker容器中的test_container文件夹?我需要自动完成。如何在不真正使用run-d-v命令的情况下做到这一点?如果boot2docker崩溃会发生什么?Docker文件存储在哪里(除了Dockerfile)?


当前回答

从Docker 18-CE开始,您可以使用Docker run-v/src/path:/container/path来进行主机文件夹的双向绑定。

不过,如果您使用的是Windows 10/WSL,并将Docker CE for Windows作为主机,然后在WSL中使用Docker CE客户端工具,那么这里有一个主要的陷阱。WSL知道整个/文件系统,而Windows主机只知道驱动器。在WSL中,您可以使用/mnt/c/projectpath,但是如果您尝试停靠运行-v${PWD}:/projectpath时,您会在主机中发现/projectpath/为空,因为在主机上/mnt意味着什么。

如果您从/c/projectpath工作,然后运行docker-v${PWD}:/projectpath,您会发现在容器中,/projectpath将实时反映/c/projectpath。除了在您的客户机中看到空装载外,没有任何错误或任何其他方法可以检测此问题。

您还必须确保在Docker for Windows设置中“共享驱动器”。

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。

您是否可以通过boot2docker或类似方式在OS X上使用docker。

我也有过同样的经历——命令是正确的,但无论如何,容器中没有装入任何(合理的)内容。

事实证明,docker文档中已经对此进行了解释。当您键入docker run-v/var/logs/on/host:/var/logs/in/container。。。那么/var/logs/on/host实际上是从boot2docker VM映像映射的,而不是从Mac映射的。

您必须通过虚拟机将共享文件夹传输到实际主机(在我的情况下是Mac)。

对于Windows 10用户,将装载点放在C:\users/目录中很重要。我花了好几个小时才把它弄好。这篇文章有所帮助,但最初并不明显,因为Windows 10的解决方案是对公认答案的评论。我是这样做的:

docker run -it -p 12001:80 -v //c/Users/C/Desktop/dockerStorage:/root/sketches \
<your-image-here> /bin/bash

然后要测试它,可以在图像中执行echo test>hostTest.txt。您应该能够在位于C:\Users/C/Desktop/dockerStorage/的本地主机文件夹中看到此新文件。

为了在Windows 10中实现这一点,我必须从系统托盘中打开Docker设置窗口,然后转到共享驱动器部分。

然后,我选中了C旁边的复选框。Docker要求我的桌面凭据以获得写入我的用户文件夹的授权。

然后,我按照上面的示例以及设置页面上的示例运行docker容器,将其附加到容器中的/data。

docker run -v c:/Users/<user.name>/Desktop/dockerStorage:/data -other -options

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.
