Nodejs 应用简单的访问Mongodb 部署至Docker

 

1.

本地简单的写能运行起来的一个nodejs (demo可写的更简单 一个post一个get即可)

schemas  user.js

var mongoose = require(‘mongoose‘)var UserSchema = new mongoose.Schema({	name:{		unique:true,		type:String	},	password:{		type:String	},	//0  1  2  3  4	role:{		type:Number,		default:5	}})UserSchema.statics = {	fetch:function(cb){		return this.find({})		.exec(cb)	},	findById:function(id,cb){		return this.findOne({_id:id}).exec(cb)	}}module.exports = UserSchema

model user.js　　

var mongoose = require(‘mongoose‘)var UserSchema = require(‘../schemas/user‘)var User = mongoose.model(‘User‘,UserSchema);module.exports = User;

controller user.js

var User = require(‘../model/user‘)exports.list = function(req,res){	User.fetch(function(err,users){		if(err) {console.log(err)}		res.send(users);	})}exports.save = function(req,res){	console.log(req.query.name);	var name = req.query.name || ‘noname‘;	var password = ‘abcdefg‘;	var user = new User({"name":name,"password":"123456"})		user.save(function(err){		if(err)		{			console.log(‘false‘);			res.send("fails");			return;		}		res.redirect(‘/‘);	})}

 

app.js

var express = require(‘express‘);var router = express.Router();var mongoose = require(‘mongoose‘)//var dbURL = ‘mongodb://localhost:27017/imooc‘;var dbURL = ‘mongodb://mongodb/imooc‘;//mongodb这个名字是 在--link=aaa:bbb时的名字 即bbbmongoose.connect(dbURL);var app = express();app.listen(3000,function(){	console.log("server start. Listen port:3000");});require(‘./router/router‘)(app)

　　router.js

var User = require(‘../app/controller/user‘)var _ = require(‘underscore‘)module.exports = function(app){	app.get(‘/‘,User.list)	app.get(‘/user‘,User.save);}

　　确保本地能够正常运行。

2.在app.js文件目录编写dockerfile

FROM nodeCOPY . /home/srcRUN cd /home/src; npm installEXPOSE 3000CMD ["node","/home/src/app.js"]

　

4.docker pull mongo 

5.docker run -it --name mongodb mongo /bin/bash  进入终端

cd /homemkdir dbmongod --dbpath=‘/home/db‘启动mongodb服务

 

6.docker build -t nodejsdemo ./　

docker run -it -p 3000:3000 --name nodejsdemo --link=mongodb:mongodb modejsdemo

此时控制台可以看到 server start Listen port:3000

 

浏览器访问 192.168.99.100:3000
