码头名为卷定位Mac

Question

我使用DockerforMac1.12.1，并拥有一个启动WordPress和MySQL服务的Docker文件

组合文件

version: '2'
services:
  db:
    container_name: mysql_db
    image: mysql:5.7
    volumes:
      - "./.data/db:/var/lib/mysql"
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: wordpress
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: wordpress

  wordpress:
    container_name: wordpress
    depends_on:
      - db
    image: wordpress:latest
    links:
      - db
    ports:
      - "8000:80"
    restart: always
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_PASSWORD: wordpress
    volumes:
      - wordpress/:/var/www/html/

volumes:
    wordpress:

但是，在成功地启动所有内容之后，我无法找到命名卷在我的Mac上的位置。

MacBookAir:wordpress carlwainwright$ docker volume inspect wordpress_wordpress
[
    {
        "Name": "wordpress_wordpress",
        "Driver": "local",
        "Mountpoint": "/var/lib/docker/volumes/wordpress_wordpress/_data",
        "Labels": null,
        "Scope": "local"
    }
]
MacBookAir:wordpress carlwainwright$ ls -l /var/lib/docker/volumes/wordpress_wordpress/_data/
ls: /var/lib/docker/volumes/wordpress_wordpress/_data/: No such file or directory

有什么想法吗？

请记住，在Linux中运行一个坞引擎，而不是在Mac中运行，所以在Mac文件系统中找不到卷的挂载点。卷文件应该存在于Linux的文件系统中。

但是，您可以通过屏幕登录Mac的VM的Docker：

$ screen ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty  
#user: root
#password: xxxxxx

然后您可以查看码头的卷：

$ ls -ltrh /var/lib/docker/volumes
total 148
drwxr-xr-x    3 root     root          4096 May 16 13:20 04576d248c19b1210d47e94c8211493428cd3c3aa71dfe3fa0f4214589a6f875
drwxr-xr-x    3 root     root          4096 May 16 13:20 31af0f01492d8f7b832dad75e731b754302e84fbecfa7c654d7de10465bec204
etc.
