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

2015年7月更新-boot2docker现在支持直接安装。您可以在Mac提示符下直接使用-v/var/logs/on/host:/var/logs/in/container,而无需双重安装

其他回答

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

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。

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 

这个问题的用户使用的是Docker版本0.9.1,构建867b2a9,我将为您提供Docker版本>=17.06的答案。

您所希望的,保持本地目录在容器目录中同步,是通过使用类型bind装载卷来实现的。这将绑定源(您的系统)和目标(docker容器)目录。这几乎与在linux上安装目录相同。

根据Docker文档,现在适当的mount命令是mount而不是-v。以下是其文档:

--mount:由多个键值对组成,用逗号分隔。每个键/值对采用<key>=<value>元组的形式。--mount语法比-v或--volume更详细,但键的顺序并不重要,标志的值更容易理解。装载的类型,可以是bind、volume或tmpfs。(我们将使用bind)装载源。对于绑定装载,这是Docker守护程序主机上文件或目录的路径。可以指定为source或src。目标将文件或目录装入容器的路径作为其值。可以指定为destination、dst或target。

因此,要使用/test_container(目标)装载当前目录(源),我们将使用:

    docker run -it --mount src="$(pwd)",target=/test_container,type=bind k3_s3

如果这些装载参数有空格,则必须在它们周围加引号。当我知道他们不知道时,我会用“pwd”代替:

    docker run -it --mount src=`pwd`,target=/test_container,type=bind k3_s3

您还需要处理文件权限,请参阅本文。

我也有同样的问题。我的命令行如下所示:

docker run --rm -i --name $NAME -v `pwd`:/sources:z $NAME

问题出在“pwd”上。所以我把它改成了$(pwd):

docker run --rm -i --name $NAME -v $(pwd):/sources:z $NAME
