Php 将mysql数据库与docker容器连接时出现问题

我正在尝试为laravel、nginx和mariadb设置一个容器。容器正在运行，但我的laravel应用程序无法访问db容器

SQLSTATE[HY000] [1045] Access denied for user 'root'@'app.app-network' (using password: NO) (SQL: select * from information_schema.tables where table_schema = appdb and table_name = migrations and table_type = 'BASE TABLE')

这是我的docker-compose.yml

version: "3.7"

services:
  app-db:
    image: mariadb:10.5.6
    container_name: app-db
    restart: unless-stopped
    tty: true
    ports: 
      - "3307:3306"
    environment: 
      MYSQL_ROOT_PASSWORD : root
      MYSQL_DATABASE: appdb
      MYSQL_USER: root
      MYSQL_PASSWORD: root
    volumes: 
      - mariadbdata:/var/lib/mysql
      - ./.dockerfile/mysql/my.cnf:/etc/mysql/my.cnf
    networks: 
      - app-network


  app-api:
    build: 
      context: .
      dockerfile: Dockerfile
    image: 'app-api'
    container_name: 'app-api'
    restart: unless-stopped
    tty: true
    working_dir: /var/www
    volumes:
      - .:/var/www
      - ./.dockerfile/php/local.ini:/usr/local/etc/php/conf.d/local.ini
    networks:
      - app-network
  
  webserver:
    image: nginx:alpine
    container_name: 'app-webserver'
    restart: unless-stopped
    tty: true
    ports: 
      - "8100:80"
      - "8143:443"
    volumes: 
      - ./:/var/www
      - ./.dockerfile/nginx/conf.d:/etc/nginx/conf.d/
    networks:
      - app-network

    
networks:
  app-network:
    driver: bridge

volumes:
  mariadbdata: 
    driver: local

我的Dockerfile

# Add user for laravel application

EXPOSE 9000
CMD ["php-fpm"]

我可以在

http://localhost:8100/

。但每次我尝试迁移时都会出现上述错误

我正在使用容器bash进行迁移

laravel的我的数据库环境

DB_CONNECTION=mysql
DB_HOST=app-db
DB_PORT=33060
DB_DATABASE=appdb
DB_USERNAME=root
DB_PASSWORD=password

---

DB_CONNECTION=mysql DB_HOST=app DB DB_PORT=33060 DB_DATABASE=appdb DB_USERNAME=root DB_PASSWORD=PASSWORD这是我的mysql配置它不是来自Laravel，它是mysql看到的你的主机名。您必须将

root@app.app network

作为有效用户添加到MySQLNo-luck@aynber，但仍然存在相同的错误。虽然我是docker新手，但我猜我的laravel容器没有访问我的db容器。我所有的配置都正确吗？
