Docker无法连接到MySQL运行Docker compose up

我正在使用此Docker配置: https://github.com/romaricp/kit-starter-symfony-4-docker

我使用以下方法启动环境:

docker合成生成

docker组合-d

一切运行正常,但MySQL服务有问题。我得到一个Symfony错误:

“驱动程序中发生异常:找不到驱动程序”

mysqli_real_connect():php_network_getaddresses:getaddrinfo失败:

你知道我该怎么做吗?

docker-compose.yml文件:

version: '3'
services:
apache:
    build: .docker/apache
    container_name: sf4_apache
    ports:
      - 80:80
    volumes:
      - .docker/config/vhosts:/etc/apache2/sites-enabled
      - .:/home/wwwroot/sf4
    depends_on:
      - php

mysql:
    image: mysql
    container_name: sf4_mysql
    volumes:
        - .docker/data/db:/var/lib/mysql
    environment:
        MYSQL_ROOT_PASSWORD: root
        MYSQL_DATABASE: sf4
        MYSQL_USER: sf4
        MYSQL_PASSWORD: sf4

php:
    build: .docker/php
    container_name: sf4_php
    volumes:
      - .:/home/wwwroot/sf4
    environment:
      - maildev_host=sf4_maildev
    depends_on:
      - maildev
      - mysql

phpmyadmin:
    image: phpmyadmin/phpmyadmin
    container_name: sf4_phpmyadmin
    ports:
        - 8080:80
    links:
        - mysql

maildev:
    image: djfarrelly/maildev
    container_name: sf4_maildev
    ports:
      - 8001:80

我还打开了mysql日志,看到了以下内容:

可能是端口错误,所以我无法连接?
