我的网站只有添加端口3000才能访问

Question

当我最后将端口 3000 添加到映射到 namecheap 上托管的域名的弹性 Ip 地址时，我只能访问托管在 ec2 实例上的网站。

我的泊坞窗包含；前端、后端、nginx 和 certbot。

当我构建 docker 项目时，一切看起来都正常，没有任何警告。

这是我的 docker compose yml 文件和 .env 文件的视图：

1-docker 撰写 yml:

  version: '3'
     services:
   # Client container
  client:
    build:
      context: frontend
      dockerfile: Dockerfile
    container_name: client
    ports:
      - "80:3000"
    volumes:
      - ./frontend:/var/www/frontend

  #Laravel App
  app:
    build:
      context: backend
      dockerfile: Dockerfile
    image: hakase-labs/laravel
    container_name: app
    restart: unless-stopped
    tty: true
    ports:
      - "80:9000"
    environment:
      SERVICE_NAME: app
      SERVICE_TAGS: dev
    working_dir: /var/www/backend
    volumes:
      - ./backend/php/local.ini:/usr/local/etc/php/conf.d/local.ini
      - ./backend:/var/www/backend
    depends_on:
      - db

  #SSL
  certbot:
    image: certbot/certbot:latest
    container_name: certbot
    volumes:
      - ./certbot/www/:/var/www/certbot/:rw
      - ./certbot/conf/:/etc/letsencrypt/:rw

  #Nginx Service
  nginx:
    image: nginx:alpine
    container_name: nginx
    restart: unless-stopped
    tty: true
    ports:
      # Nuxt port
      - "80:80"
      # Laravel port
      - "81:81"
      - "443:443"
    volumes:
      - ./:/var/www
      - ./certbot/www:/var/www/certbot/:ro
      - ./certbot/conf:/etc/letsencrypt/:ro
      - ./nginx/config/default.conf:/etc/nginx/conf.d/default.conf
      - ./nginx/config/nginx.conf:/etc/nginx/nginx.conf
    depends_on:
      - app
      - client

  #MySQL Service
  db:
    image: mysql:5.7
    container_name: db
    restart: unless-stopped
    tty: true
    ports:
      - "3306:3306"
    environment:
      MYSQL_DATABASE: *******
      MYSQL_USER: **************
      MYSQL_PASSWORD: **************
      MYSQL_ROOT_PASSWORD: *************
    volumes:
      - mysqldata:/var/lib/mysql/
#Docker Networks
# networks:
  # mynet:
    # driver: bridge
#Volumes
volumes:
  mysqldata:
    driver: local

2-nginx 默认配置文件：

PS；我的 ec2 实例的安全组内允许使用端口 80 和 443。 我在入站规则中添加了 3000 端口作为 TCP，当我将此 3000 端口添加到我的网站时，我可以访问它。

我想要的是使用默认的http端口80访问我的网站。

谢谢

我尝试将 docker compose yml 文件中的端口更改为 80，但是当我构建 docker 映像时，它说端口 80 已分配

您可以执行一次 docker ps 并检查您的 docker 容器所遵循的实际端口映射是什么吗？这将有助于排除故障。
