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

我也遇到了同样的问题,我试图在docker上装载C:\Users\folder这是我如何在Docker工具箱命令行中执行的

 $ docker run -it --name <containername> -v /c/Users:/myVolData <imagename>

其他回答

您可以从cli中使用-v选项,该工具无法通过Dockerfile使用

docker运行-t-i-v<host_dir>:<container_dir>ubuntu/bin/bash

其中host_dir是要装载的主机目录。如果容器的目录不存在,您不必担心,docker会创建它。

如果您从主机(在root权限下)对host_dir进行任何更改,则容器将看到它,反之亦然。

有几种方法可以做到这一点。最简单的方法是使用dockerfile ADD命令,如下所示:

ADD . /path/inside/docker/container

但是,在构建dockerfile之后,在主机上对该目录所做的任何更改都不会显示在容器中。这是因为在构建容器时,docker将目录压缩为.tar,并将该上下文永久上传到容器中。

第二种方法是尝试装载卷。由于尽可能地可移植,您无法将主机目录映射到dockerfile中的docker容器目录,因为主机目录可能会根据您正在运行的计算机而改变。要将主机目录映像到docker容器,您需要在使用dockerrun时使用-v标志,例如:

# Run a container using the `alpine` image, mount the `/tmp`
# directory from your host into the `/container/directory`
# directory in your container, and run the `ls` command to
# show the contents of that directory.
docker run \
    -v /tmp:/container/directory \
    alpine \
    ls /container/directory

使用命令行:

docker run -it --name <WHATEVER> -p <LOCAL_PORT>:<CONTAINER_PORT> -v <LOCAL_PATH>:<CONTAINER_PATH> -d <IMAGE>:<TAG>

使用docker-compose.yaml:

version: '2'
  services:
    cms:
       image: <IMAGE>:<TAG>
       ports:
       - <LOCAL_PORT>:<CONTAINER_PORT>
       volumes:
       - <LOCAL_PATH>:<CONTAINER_PATH>

假设:

图片:k3_s3标签:最新本地端口:8080容器端口:8080LOCAL_PATH:/要装载的卷容器路径:/mnt

示例:

首先创建要装载的/卷。(如果存在,则跳过)

$ mkdir -p /volume-to-mount

docker compose-f docker-compose.yaml up-d

version: '2'
  services:
    cms:
       image: ghost-cms:latest
       ports:
       - 8080:8080
       volumes:
       - /volume-to-mount:/mnt

验证容器:

docker exec -it CONTAINER_ID ls -la /mnt

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.
;

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 

从官方网站引用:

确保之前没有运行任何入门容器。从应用程序目录运行以下命令。

解释:

注意,这是Dockerfile sh-c“yarn install&&yarn run dev”命令中应用程序的基本映像。

我们正在使用sh(alpine没有bash)启动一个shell,并运行yarn install来安装所有依赖项,然后运行yarn run dev。如果我们查看package.json,我们将看到dev脚本正在启动nodemon。
