使用Windows主机时如何挂载Docker卷?
在Windows主机下安装Docker卷对我来说是一个巨大的痛苦,而且我无法使其正常工作。
目前,我得到了以下简单的Dockerfile:
FROM php:5-apacheRUN apt-get update
当我从中构建图像并启动容器时
docker build -t phisch:dev .docker run phisch:dev
容器正常启动。
但是当我尝试装载一个卷时,
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:devno such file or directory
docker: Error response from daemon: Container command not found or does not exist..
该/var/www
目录肯定存在于容器中,尝试其他目录不会更改结果。在主机端目录前添加斜杠也无济于事。(//c/Users/phisch/dev/htdocs
)
例如/var/www
,如何安装到C:/Users/phisch/dev/htdocs
?
phisch@DESKTOP-UC1LB9J MINGW64 ~/dev (master)$ docker inspect phisch:dev

CMD Windows shell 可能会将其解释为选项。
首先尝试使用docker-machine ssh默认设置,以便在VM中打开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在第18290期中所评论的:
您可以考虑使用docker-compose;docker-
compose允许您定义相对于
docker-compose.yml
文件位置的绑定安装卷。使用
docker-
compose文件可让您在单个文件中指定运行容器所需的所有选项,这使其非常适合在团队成员之间共享(即,只要运行即可
docker-compose up
-d使用正确的选项启动项目的所有容器)。
此评论提到了第二个/:
docker run -v //c/Users/phisch/dev/htdocs:`/var/www` phisch:dev
即使在docker toolbox msys
shell会话中,也存在问题(例如问题282)
经过长时间的讨论,问题在于其中/var/www
有一个文件夹。
挂载 /c/Users/phisch/dev/htdoc
到空文件夹确实可以,但是可能无法获得预期的结果,因为默认CMD
apache2-foreground
可能仍根据其内容提供内容/var/www
(htdocs
如果将htdocs
其安装到另一个文件夹中则不会包含任何内容)。
