在使用Windows主机时如何安装Docker卷？ [英] How to mount a docker volume while using a windows host?

问题描述

目前，我得到了一个在Windows主机下安装Docker卷，对我来说是一个巨大的痛苦，我无法让它工作。以下简单的Dockerfile：

  FROM php：5-apache 
 RUN apt-get update 
  

当我从中构建一个图像，并启动一个容器

  docker build -t phisch：dev。 
 docker运行phisch：dev 
  

容器正常启动。

但是当我试图安装一个卷时：

  docker run -v / c / Users / phisch / dev / htdocs：/ var / www phisch：dev 
  

将显示以下消息：

  C：\Users\phisch\dev> docker run -v / c / Users / phisch / dev / htdocs ：/ var / www phisch：dev 
没有这样的文件或目录
 docker：来自守护进程的错误响应：未找到或不存在的容器命令
  / pre> 
 
 
容器中存在 / var / www 目录，尝试其他目录不会更改结果。为主机端目录预设斜线也不会有帮助。 （ // c / Users / phisch / dev / htdocs ）
 
 
 
如何挂载例如 / var / www  to  C：/ Users / phisch / dev / htdocs ？

  out，容器端目录 / var / www 需要为空，因为它有一个子目录 www 码头工作者无法使用它作为安装点。
解决方案
可能 / 被CMD Windows shell解释为一个选项。
 
 
 
首先尝试一个docker-machine ssh default，以便打开你的虚拟机中的ssh会话。从那里尝试docker再次运行： docker run -v / c / Users / phisch / dev / htdocs：/ var / www phisch：dev  
 
 
 
正如 thaJeztah 在 issue 18290 ：
 
 
您可以考虑使用 docker-compose ; docker-compose允许您相对于 docker-compose.yml 文件的位置来定义绑定的卷。
 
使用 docker-compose 文件允许您指定在单个文件中运行容器所需的所有选项，这使其成为团队成员之间共享的理想选择（即，只需运行 docker -   code code code code code 
 
 $ p $ href =https://github.com/docker/docker/issues/18290#issuecomment-175191098 =nofollow>这个评论提到了一个& dding第二个/：
  docker run -v // c / Users / phisch / dev / htdocs：`/ var / www` phisch：dev 
  
即使在docker工具箱的msys shell会话中也有问题（比如问题282 ）
 
 
 
 
 
 
经过漫长的讨论，问题是 / var / www 有一个fo 
 
 
 
将 / c / Users / phisch / dev / htdoc 挂载到空文件夹中，但是可能不会给出预期的结果，因为默认的CMD  apache2-foreground 可能仍然基于 / var / www （如果 htdocs 被安装到另一个文件夹上），则不会有 htdocs 内容。
 
Mounting a docker volume while being under a windows host, has been a huge pain for me, and i could not get it to work.

Currently i got the following simple Dockerfile:
FROM php:5-apache
RUN apt-get update
When i build an image from it, and start a container
docker build -t phisch:dev .
docker run phisch:dev
the container starts properly.

But when i am trying to mount a volume:
docker run -v /c/Users/phisch/dev/htdocs:/var/www phisch:dev
the following message will be displayed:
C:\Users\phisch\dev>docker run -v /c/Users/phisch/dev/htdocs:/var/www phisch:dev
no such file or directory
docker: Error response from daemon: Container command not found or does not exist..
The /var/www directory definetely exists in the container, trying other directorys does not change the result. Prepending a trailing slash to the host-side directory does not help either. (//c/Users/phisch/dev/htdocs)

How to mount for example /var/www to C:/Users/phisch/dev/htdocs?

Turns out, the container-side directory /var/www needs to be empty, since it had a sub-directory www, docker was not able to use it as a mounting point.
解决方案
It is possible the / is interpreted as an option by the CMD Windows shell.

Try first a docker-machine ssh default, in order to open an ssh session in your VM. From there try the docker run again: docker run -v /c/Users/phisch/dev/htdocs:/var/www phisch:dev

As commented by thaJeztah in issue 18290:

  
You could consider using docker-compose; docker-compose allows you to define bind-mounted volumes relative to the location of the docker-compose.yml file.

  Using a docker-compose file allows you to specify all options needed to run your containers in a single file, which makes it ideal for sharing between team members (ie, just run docker-compose up -d will start all containers for the project with the right options).
This comment mentions a&dding a second /:
docker run -v //c/Users/phisch/dev/htdocs:`/var/www` phisch:dev
Even in the docker toolbox msys shell session, there are issues (like issue 282)



After lengthy discussion, the issue was that /var/www had a folder in it.

Mounting  /c/Users/phisch/dev/htdoc onto an empty folder does work, but might not give the expected result, as the default CMD apache2-foreground might still serve its content based on /var/www (which would not have htdocs content if that htdocs is mounted onto another folder).
