如何使用docker在nginx web服务器上部署我的express web应用程序？

# 使用Node.js作为基础镜像
FROM node:latest

# 设置工作目录
WORKDIR /app

# 复制package.json和package-lock.json到工作目录
COPY package*.json ./

# 安装应用程序的依赖
RUN npm install

# 复制应用程序代码到工作目录
COPY . .

# 暴露应用程序使用的端口
EXPOSE 3000

# 启动应用程序
CMD [ "npm", "start" ]

version: '3'
services:
  web:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "80:3000"
    depends_on:
      - nginx
  nginx:
    image: nginx:latest
    ports:
      - "80:80"
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf:ro

events {}

http {
  server {
    listen 80;
    server_name localhost;

    location / {
      proxy_pass http://web:3000;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection 'upgrade';
      proxy_set_header Host $host;
      proxy_cache_bypass $http_upgrade;
    }
  }
}

docker-compose up --build
