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?

is your server.js file on the same directory as the Dockerfile? I think the problem is that server.js has to also be in WORKDIR. And also I think you're copying your code to the container on this one, use CP instead of RUN mv. Try this:

FROM node:onbuild

WORKDIR /app

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

ADD server.js /app/server.js # add this line

EXPOSE 3000

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

updated it: I incorrectly wrote CP instead of the correct COPY, Sorry :(

I tried your solution, but the result is still the same. The "CP" command was not found, so I kept the older line. – chrisonstack May 05 '16 at 18:29
sorry, its supposed to be COPY not CP, I updated my answer, my bad – paolord May 05 '16 at 18:33
I tried with COPY and it fails too. Basically docker-compose is not installed on OVH's VPS. Even if it's possible to install it, maybe we can't use it... furthermore I found some tutorials provided by OVH and it explains How to set up three containers without docker-compose. – chrisonstack May 06 '16 at 17:04
oh, I thought you ran docker-compose on ovh, – paolord May 07 '16 at 06:17

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 :)

That help, has same problem.... It looks like problem with path `- .:/app` — Vladimir, Apr 09 '17 at 12:26
