这是我的 docker-compose

version: "3.7"
services:

  web:
    image: nginx:latest
    container_name: nginx-container
    ports:
      - "8080:80"
    volumes:
      - ./:/var/www/firstweb
      - ./default.conf:/etc/nginx/conf.d/
    links:
      - php

  php:
    image: php:7-fpm
    container_name: php-container
  db:
    image: mysql
    container_name: mysql-container
    command: --default-authentication-plugin=mysql_native_password
    volumes:
      - ./mysql-data:/var/lib/mysql
    expose:
      - 3306
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: rootpass

和 my default.conf
