node.js-节点Docker运行,但看不到该应用程序

看来我的Hapi应用正在Docker容器中运行,但无法在浏览器中找到它.我以为docker run -d -p 8080：3000可以做到,但我想没有.我正在引导至docker,并且http：// localhost：8080 / hello或http://192.168.99.100:8080/hello都无法正常工作.

我也尝试过很多变化.

这是我在运行docker inspect< container id>时看到的内容：

Server running at: http://localhost:8080

这是我的Hapi.js服务器：

'use strict';

const Hapi = require('hapi');

// Create a server with a host and port
const server = Hapi.server({
    host: 'localhost',port: 3000
});

// Add the route
server.route({
    method: 'GET',path:'/hello',handler: function (request,h) {
        return 'hello world';
    }
});

async function start() {

    try {
        await server.start();
    }
    catch (err) {
        console.log(err);
        process.exit(1);
    }

    console.log(`App running at: ${server.info.uri}/hello`);
}

start();

这是我的Dockerfile：

FROM node:8.9.3

MAINTAINER My Name <email@email.com>

ENV NODE_ENV=production
ENV PORT=3000
ENV user node

WORKDIR /var/www
COPY package.json yarn.lock ./

RUN cd /var/www && yarn

COPY . .

EXPOSE $PORT

ENTRYPOINT ["yarn","start"]

这是我的package.json：
