容器看不到注册的用户名和密码

Question

我决定将docker配置为与laravel一起使用，并遇到了问题。这是我的docker-compose.yml，除了mysql以外，一切似乎都可以正常工作。

这是我的docker-compose.yml文件。

version: '3.7'

services:
  #PHP Service
  app:
    build:
      context: .
      dockerfile: Dockerfile
    image: digitalocean.com/php
    container_name: app
    environment:
      - SERVICE_NAME=app
      - SERVICE_TAGS=dev
    working_dir: /var/www
    volumes:
      - ./:/var/www
      - ./php/local.ini:/usr/local/etc/php/conf.d/local.ini
    networks:
      - app-network

  #Nginx Service
  webserver:
    image: nginx:alpine
    container_name: webserver
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./:/var/www
      - ./nginx/conf.d/:/etc/nginx/conf.d/
    networks:
      - app-network

  #MySQL Service
  db:
    image: mysql:5.7.22
    container_name: db
    ports:
      - "3306:3306"
    environment:
      - MYSQL_ALLOW_EMPTY_PASSWORD=1
      - MYSQL_DATABASE=laravel
      - MYSQL_USER=service
      - MYSQL_PASSWORD=servicepass
    volumes:
      - dbdata:/var/lib/mysql/
      - ./mysql/my.cnf:/etc/mysql/my.cnf
    networks:
      - app-network

#Docker Networks
networks:
  app-network:
    driver: bridge
#Volumes
volumes:
  dbdata:
    driver: local

当我使用mysql进入容器并输入

 mysql -uroot -p 

或

mysql -uservice -pservicepass

我收到此错误-

ERROR 1045 (28000): Access denied for user 'service' @ 'localhost' (using password: YES).
