Docker Compose

Docker Compose

Dockerfile provides a declaritive way of building images

Write a Dockerfile

version: '2'
services:
  db:
    image: mongo:latest
    container_name: db
    networks:
      - appnet
  web:
   build: ../.
   networks:
     - appnet
   ports:
    - "3000"
networks:
  appnet:
     driver: bridge

Specifically in this example there is no port defined for the localhost in order to be able to scale the web application
