Running with Docker

You can Dockerize your app with just a few changes.

Step 1

Create a Dockerfile in the root directory:

FROM node
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY package.json /usr/src/app/
RUN npm install
COPY . /usr/src/app
EXPOSE 8000
CMD [ "npm", "start" ]

Step 2

Create a docker-compose.yml in the root directory:

version: '2'
services:
  app:
    build: .
    ports:
      - "8000:8000"
    environment:
      - MONGODB_URI_DEFAULT=mongodb://db:27017/aqua
    links:
      - db
  db:
    image: mongo
    ports:
      - "27017:27017"

Step 3

Change config.js to accept the MongoDB URI via environment variables:

            uri: {
                 $filter: 'env',
                 production: process.env.MONGODB_URI,
-                test: 'mongodb://localhost:27017/aqua-test',
-                $default: 'mongodb://localhost:27017/aqua'
+                test: process.env.MONGODB_URI_TEST,
+                $default: process.env.MONGODB_URI_DEFAULT
             }
         },
         autoIndex: true

Run it

Now to run the app simply:

$ docker-compose up

That's it
