Add Docker config option under Deployment about megaboilerplate

[MikeMichel]

argh, just finished the second blog post about the "old" hackathon-starter. however, megaboilerplate looks awesome. The dev docker-compose.yml i created still works with the express+mongodb+jade combi.

version: '2'
services:

  web:
    image: node:6.1
    volumes:
      - ./:/usr/src/app
    working_dir: /usr/src/app
    command: sh -c 'npm install; npm install -g nodemon ; nodemon -e js,jade app.js'
    ports:
      - "80:3000"
    depends_on:
      - mongo
    networks:
      - all
    environment:
      MONGODB: "mongodb://mongo:27017/hackathon"

  mongo:
    image: mongo:3
    command: mongod --smallfiles
    networks:
      - all

networks:
  all:

same for the Dockerfile:

FROM node:6.1.0

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

COPY . /usr/src/app/
RUN npm install

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

What do you have in mind? Generating only buildfiles regarding the choosed frameworks or docker-compose.yml files too?

btw. in hackathon-starter you switched from MONGODB to MONGODB_URI

cheers,

Hey Mike, having not used Docker or Docker Compose I have a little difficulty understanding of where these tools fit in the workflow and the difference between Docker and Docker Compose. From the docs:

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application’s services.

But that still doesn't tell me much.

I think I understand the purpose behind Docker - it's to specify all system dependencies like Node.js, MongoDB, PostgreSQL, configure a database, install build tools, and finally run the app. So, with a single command you can start an app without having to install all those prerequisites on your machine. That's Dockerfile. Something like that could be a checkbox option under Platform or Framework selection.

Now where does Docker Compose fit in this picture?

Hey @sahat

Docker Compose allows you to specify multiple containers per project (eg. one for database, another for web) Each can have different Docker images fit for purpose, which may connect to different code bases within your project tree, etc.

I'm thinking Docker would be a nice way to support several hosting platforms (DigitalOcean has one-click Docker instances, for example) Would be easy enough to incorporate deployment scripts for each.
Thoughts?

Keep up the great work, I'm excited!
