我想制作简单的restful API。我正在使用docker来做到这一点。这里是我的Dockerfile：docker尝试连接到mongodb时出错
FROM mongo:3.2
EXPOSE 3000
RUN apt-get update; apt-get install curl -y
RUN curl -sL https://deb.nodesource.com/setup_6.x | bash -
RUN apt-get install -y nodejs
ADD . .
CMD node app.js
我docker-compose.yml看起来是这样的：
version: '2'
services:
db:
build: ../images/mongodb
ports:
- "27017:27017"
- "3000:3000"
我app.js文件看起来像这样：
var express = require('express')
var app = express()
var mongoose = require('mongoose');
mongoose.Promise = global.Promise;
mongoose.connect('mongodb://127.0.0.1:27017/sample');
app.get('/', function (req, res) {
res.send('Hello World!')
})
app.listen(3000, function() {
console.log('Example app listening on port 3000!')
})
在运行时docker-compose up --build，我有错：
db_1 | Example app listening on port 3000!
db_1 |
db_1 | events.js:160
db_1 | throw er; // Unhandled 'error' event
db_1 | ^
db_1 | MongoError: failed to connect to server [127.0.0.1:27017] on first connect [MongoError: connect ECONNREFUSED 127.0.0.1:27017]

我曾尝试在泊坞窗机一起去docker run -it mongo:3.2 /bin/bash

有人可以帮我解决这个问题？
感谢您的回答，如何设置路径为我Dockerfiles数据库和应用程序 – dmx
改变了我的答案@dmx让我知道，如果这是你的意思 –
