无法访问此站点localhost拒绝连接

问题描述

我正在尝试将此应用程序转换为 docker 但我无法访问此站点 localhost 拒绝连接.. 即使我尝试使用 docker-compose 这是我的 express.js 文件

const express = require("express");
const app = express();
const portNumber = 3000;
const sourceDir = "dist";
const expressstaticGzip = require("express-static-gzip");
app.use(
  "/",expressstaticGzip(sourceDir,{
    enablebrotli: true,orderPreference: ["br","gz"],setHeaders: function(res,path) {
      res.setHeader("Cache-Control","public,max-age=31536000");
    }
  })
);

app.listen(portNumber,"0.0.0.0",() => {
  console.log(`Express web server started: http://0.0.0.0:${portNumber}`);
  console.log(`Serving content from /${sourceDir}/`);
});

这是我的 package.json

给。 dockerfile

FROM node:14

workdir /app

ENV PATH /app/node_modules/.bin:$PATH

copY package.json ./
copY package-lock.json ./
RUN npm install

copY . ./

CMD [ "node","express.js" ]

给。 docker-compose.yml 文件

version: '3.7'

services:

  place-app:
    container_name: place-app
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - '.:/app'
      - '/app/node_modules'
    ports:
      - 3001:3000
    environment:
      - CHOKIDAR_USEPOLLING=true

docker build 成功创建，图像标记成功，容器构建成功，但是当我尝试在本地主机上连接时，它说无法访问该站点本地主机拒绝连接感谢帮助。
