上示例中，指定在本地创建了两个存储桶：

volumes:
  mariadb_data:
    driver: local
  prestashop_data:
    driver: local

可以通过以下命令来查询已创建的volume

docker volume ls

如果想要查看存储的位置

docker volume inspect ps8_prestashop_data

指定存储路径

volumes:
  mariadb_data:
    driver: local
    driver_opts:
      type: none
      device: /path/on/host
      o: bind
  prestashop_data:
    driver: local
    driver_opts:
      type: none
      device: /path/on/host
      o: bind
