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。

目前我得到了以下简单的 Dockerfile:

FROM php:5-apache
RUN apt-get update

当我从它构建一个图像并启动一个容器时

docker build -t phisch:dev .
docker run phisch:dev

容器正常启动。

但是当我尝试挂载一个卷时，

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
no such file or directory
docker: Error response from daemon: Container command not found or does not exist..

容器中肯定存在/var/www目录，尝试其他目录并不会改变结果。在主机端目录前添加一个斜杠也无济于事。 (//c/Users/phisch/dev/htdocs)

如何将例如 /var/www 挂载到 C:/Users/phisch/dev/htdocs？

原来容器端目录 /var/www 需要为空，因为它有一个子目录 www。 Docker 无法将其用作安装点。

最佳答案

/ 可能被 CMD Windows shell 解释为一个选项。

首先尝试使用 docker-machine ssh 默认值，以便在您的 VM 中打开 ssh session 。从那里再次尝试 docker run:docker run -v/c/Users/phisch/dev/htdocs:/var/www phisch:dev

正如 thaJeztah 所评论的那样在 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提到和添加第二个/:

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

即使在 docker 工具箱 msys shell session 中，也存在问题(如 issue 282)

Pyetro the comments 中的注释:

In Windows, a double slash is needed at the beginning of the path to indicate the working directory.
Just to work with short path use like this:

docker run -v //$(PWD)/folder:/folder ...

经过长时间的讨论，问题是 /var/www 中有一个文件夹。

将 /c/Users/phisch/dev/htdoc 安装到空文件夹上确实有效，但可能不会给出预期的结果，因为默认 CMD apache2-foreground可能仍会基于 /var/www 提供其内容(如果 htdocs 安装到另一个文件夹，则不会有 htdocs 内容)。
