装入卷时无法运行mariadb

使用以下docker-compose.yml文件

version: '2' services: wordpress: image: wordpress ports: - 8080:80 environment: WORDPRESS_DB_NAME: my_db WORDPRESS_DB_USER: root WORDPRESS_DB_PASSWORD: password volumes: - ./src:/var/www/html mysql: image: mariadb environment: MYSQL_ROOT_PASSWORD: password volumes: - ./data_dir:/var/lib/mysql 

当运行docker-compose up commande时，它给我下面的错误

但如果我从MySQL映像中删除卷，那么它工作正常！ 如何安装卷，因为我需要持久化数据。
