postgres和mysql挂载被拒绝docker

Question

我刚接触docker，在命令行中运行此脚本后遇到错误：

docker-compose up postgres-95 mysql-57

为了给你提供更多的背景信息，我正在尝试为Sequelize做贡献，我遵循了https://github.com/sequelize/sequelize/blob/master/CONTRIBUTING.md#coding-guidelines的指示

ERROR: for mysql-57  Cannot start service mysql-57: Mounts denied:
The path /mnt/sequelize-mysql-ramdisk
is not shared from OS X and is not known to Docker.
You can configure shared paths from Docker -> Preferences... -> File Sharing.
See https://docs.docker.com/docker-for-mac/osxfs/#namespaces for more info.

Starting postgres-95 ... error
ERROR: for postgres-95  Cannot start service postgres-95: Mounts denied:

任何帮助都将不胜感激！

编辑:不知道这是否有帮助，但这里是docker-compose.yml：

# PostgreSQL
  postgres-95:
    image: sushantdhiman/postgres:9.5
    environment:
      POSTGRES_USER: sequelize_test
      POSTGRES_PASSWORD: sequelize_test
      POSTGRES_DB: sequelize_test
    volumes:
      - /mnt/sequelize-postgres-ramdisk:/var/lib/postgresql/data
    ports:
      - "8998:5432"
    container_name: postgres-95

  # MySQL
  mysql-57:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: lollerskates
      MYSQL_DATABASE: sequelize_test
      MYSQL_USER: sequelize_test
      MYSQL_PASSWORD: sequelize_test
    volumes:
      - /mnt/sequelize-mysql-ramdisk:/var/lib/mysql
    ports:
      - "8999:3306"
    container_name: mysql-57

Answer 1

嘿，我遇到了同样的问题，似乎是由于权限问题。https://docs.docker.com/docker-for-mac/osxfs/#access-contro我是这样解决的：

1. 通过在consle sudo /mnt中写入来创建一个mnt目录(在我的例子中，我试图安装postgres，所以我必须运行sudo /mnt/postgres/data)。确保您是在根路径中创建它。
2. 转到Docker ->首选项->文件共享并添加您只需将其创建的/mnt目录！。

希望它能工作！:)

通过在根目录中创建mnt目录解决了我的问题。
