docker-compose 掛載單個文件帶目錄

[英]docker-compose mount single file with directory

如果我將文件放在相對於 docker-compose up 命令的子目錄 (myconfig) 中,則無法掛載文件。 $PWD 是 /home/username/temp/ 和 docker-compose 從那里運行。

這不起作用:

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,如果我將 nginx.conf 復制到 $PWD 目錄,則此方法有效:

version: '3'
services: 
  proxy:
    container_name: proxy
    image: nginx
    ports:
      - "80:80"
    volumes:
      - $PWD/nginx.conf:/etc/nginx/conf.d/default.conf

所以這些都不起作用:

$PWD/myconfig/nginx.conf
./myconfig/nginx.conf
/home/username/temp/myconfig/nginx.conf

但是這些工作,如果我將 $PWD/myconfig/nginx.conf 復制到 $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,當我使用長語法時,它正在使用子目錄:

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

這是我想念的東西,還是這是一個錯誤或缺乏文檔?

你的例子對我來說很好。

# docker-compose --version
docker-compose version 1.25.0, build unknown

由於您提到即使使用顯式路徑它也不起作用,而它在您的主文件夾中工作時,我建議檢查myconfig文件夾的權限。 確保所有用戶都被允許訪問和讀取('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

如果權限不正確,請使用chmod a+xr myconfig/chmod a+r myconfig/nginx.conf設置
