Full App Lifecycle with Compose

Live The Dream!
Single set of Compose files for:
- Local docker-compose up development environment
- Remote docker-compose up CI environment
- Remote docker stack deploy production environment
Note: docker-compose -f a.yml -f b.yml config mostly works
- Currently there is a bug with secrets
Note: Compose extends: doesn't work yet in Stacks

Production Config

When we have split config into multiple files we can generate prod config like:

~> docker-compose -f docker-compose.yml -f docker-compose.prod.yml config
secrets:
  psql-pw:
    external: true
services:
  drupal:
    image: bretfisher/custom-drupal:latest
    ports:
    - 80:80/tcp
    volumes:
    - drupal-modules:/var/www/html/modules:rw
    - drupal-profiles:/var/www/html/profiles:rw
    - drupal-sites:/var/www/html/sites:rw
    - drupal-themes:/var/www/html/themes:rw
  postgres:
    environment:
      POSTGRES_PASSWORD_FILE: /run/secrets/psql-pw
    image: postgres:9.6
    secrets:
    - source: psql-pw
    volumes:
    - drupal-data:/var/lib/postgresql/data:rw
version: '3.1'
volumes:
  drupal-data: {}
  drupal-modules: {}
  drupal-profiles: {}
  drupal-sites: {}
  drupal-themes: {}

~> docker-compose -f docker-compose.yml -f docker-compose.prod.yml config > output.yml
