How to use docker-compose on ovh hosting

Question

I'm still not able to properly run docker-compose in my OVH VPS.

I'm developing a small nodeJS application using mongodb. My configuration works on my PC (Windows 7), but when I push it on my VPS the result is not as expected.

My docker-compose.yml

db:
  image: mongo
  ports:
    - "27017:27017"
  command: "--smallfiles --logpath=/dev/null"
web:
  build: .
  volumes:
    - .:/app
  ports:
    - "3000:3000"
  links:
    - db
  environment:
    PORT: 3000

My Dockerfile (for the nodeJS part)

FROM node:onbuild

WORKDIR /app

ADD package.json /app/package.json
RUN npm install && npm ls
RUN mv /app/node_modules /node_modules

EXPOSE 3000

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

My nodeJS server

var mongoose = require('mongoose'); 
var express = require('express');

var MONGO_DB;
var DOCKER_DB = process.env.DB_PORT;
if ( DOCKER_DB ) {
  MONGO_DB = DOCKER_DB.replace( 'tcp', 'mongodb' ) + '/app';
} else {
  MONGO_DB = process.env.MONGODB;
}
var retry = 0;

mongoose.connect(MONGO_DB);



const app = express();

app.get('/', function (req, res) {
  res.send('Hello world\n');
});

app.listen(process.env.PORT || 3000);

The docker version on my server (Ubuntu 14.04)

Client:
 Version:      1.11.1
 API version:  1.23
 Go version:   go1.5.4
 Git commit:   5604cbe
 Built:        Tue Apr 26 23:30:23 2016
 OS/Arch:      linux/amd64

Server:
 Version:      1.11.1
 API version:  1.23
 Go version:   go1.5.4
 Git commit:   5604cbe
 Built:        Tue Apr 26 23:30:23 2016
 OS/Arch:      linux/amd64

When I run:

docker-compose up -d --build

All works fine, but at the end only the mongo container is running and the NodeJS is stopped.

Anyone has an idea?

I found a solution ! MyDockerfile looks like this

FROM node:onbuild

# Create app directory
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# Install app dependencies
COPY package.json /usr/src/app/
RUN npm install

# Bundle app source
COPY . /usr/src/app

EXPOSE 3000
CMD [ "node", "server.js" ]

And the docker-compose.yml

db:
  image: mongo
  ports:
    - "27017:27017"
web:
  build: .
  volumes:
    - .:/app
  ports:
    - "3000:3000"
  links:
    - db

All works fine right now :)
