如果我将文件放在相对于 docker-compose up 命令的子目录 (myconfig) 中,我将无法挂载文件。 $PWD 是 /home/username/temp/ 并且从那里运行 docker-compose up。
这不起作用:
version: '3'
services:
proxy:
container_name: proxy
image: nginx
ports:
- "80:80"
volumes:
- $PWD/myconfig/nginx.conf:/etc/nginx/conf.d/default.conf
但是如果我将 nginx.conf 复制到 $PWD 目录,这会起作用:
version: '3'
services:
proxy:
container_name: proxy
image: nginx
ports:
- "80:80"
volumes:
- $PWD/nginx.conf:/etc/nginx/conf.d/default.conf
所以这些都不起作用:
$PWD/myconfig/nginx.conf
./myconfig/nginx.conf
/home/username/temp/myconfig/nginx.conf
但是这些工作,如果我将 $PWD/myconfig/nginx.conf 复制到 $PWD/config.conf:
./nginx.conf
$PWD/nginx.conf
日志:
Creating network "temp_default" with the default driver
Creating proxy ... error
ERROR: for proxy Cannot create container for service proxy: not a directory
ERROR: for proxy Cannot create container for service proxy: not a directory
ERROR: Encountered errors while bringing up the project.
但是,当我使用长语法时,它正在使用子目录:
version: '3'
services:
proxy:
container_name: proxy
image: nginx
ports:
- "80:80"
volumes:
- type: bind
source: $PWD/myconfig/nginx.conf
target: /etc/nginx/conf.d/default.conf
这里有什么我想念的吗,或者这是一个错误或缺乏文档?

你的例子对我来说很好。
# docker-compose --version
docker-compose version 1.25.0, build unknown
既然您提到即使使用显式路径它也不起作用,但它在您的主文件夹中工作时,我建议检查 myconfig
文件夹的权限。确保所有用户都被允许访问和阅读('x' 和 'r')
# ls -ltr
total 8
drwxr-xr-x 2 root root 4096 Feb 23 06:03 myconfig
-rw-r--r-- 1 root root 182 Feb 23 06:05 docker-compose.yml
如果权限不正确,用chmod a+xr myconfig/
和chmod a+r myconfig/nginx.conf
设置
