Volumes for nginx container can be mounted from the environment file

[kneerunjun]

services:
  nginx:
    build: ./nginx
    ports:
      - "80:80"
    volumes: 
      # for local development the volume mapping changes
      # - "/home/niranjan/repos/eensymachines.in/luminapi/nginx/luminapp:/var/www/luminapp"
      - "/root/repos/eensymachines.in/luminapi/nginx/luminapp:/var/www/luminapp"

Its counter productive to change the volume definition everytime. need to pick this from environment file
