Docker Compose

Standard compose file with environment variables:


services:
  app:
    image: my-app
    build:
      context: ../..
      dockerfile: Dockerfile.app
    ports:
      - "${APP_PORT}:3000"
    environment:
      DB_PASSWORD: ${DB_PASSWORD}
      ENV: ${ENV}
    networks:
      - app-network
 
networks:
  app-network:

All files in .deployment/docker/ are automatically processed with Jinja2 templating.

Environment Isolation (Automatic)

By default, ${ENV} and ${VERSION} are automatically added to:

Image names
Container names

This ensures complete isolation between different environments (production, staging, etc.).

Volumes and networks are automatically prefixed with the stack name by Docker Swarm (e.g., myapp-production_volname), so they don’t need additional environment suffixes.
