Docker组合不使用指定位置的版本2卷

我无法弄清楚docker撰写的版本2。 一切正常版本1，但现在似乎忽略了数据库的volumes_from，每当我启动它，重build后，数据库已经有一个在不同的容器中的数据库，不运行，所以它不是'使用下面的sql-data中指定的卷位置？

version: '2' services: apache: container_name: "quotationspro_fix_apache_1" build: ./images/apache/ ports: - "80:80" - "443:443" volumes_from: - application php-fpm: container_name: "quotationspro_fix_phpfpm_1" build: ./images/php-fpm-7.0/ expose: - 9000 volumes_from: - application sql-server: container_name: "quotationspro_fix_sql_1" image: mariadb:10.1 environment: MYSQL_ROOT_PASSWORD: MYSQL_DATABASE: MYSQL_USER: MYSQL_PASSWORD: volumes_from: - sql-data ports: - "3306:3306" expose: - 3306 sql-data: container_name: "quotationspro_fix_sqldata_1" image: mariadb:10.1 volumes: - ./database/fix:/var/lib/mysql/data application: container_name: "quotationspro_fix_app_1" image: php:7.0-fpm volumes: - ../www:/var/www/html - ./images/app/fix-settings.inc.php:/var/www/html/config/settings.inc.php command: "true" phpmyadmin: container_name: "quotationspro_fix_phpmyadmin_1" image: phpmyadmin/phpmyadmin ports: - "8080:80" environment: PMA_HOST: "sql-server" PMA_POST: "3306"
