Deployment Strategy

Docker Organization

docker/
├── nginx/                  # Nginx configuration
│   ├── nginx.conf         # Main Nginx config
│   └── conf.d/           # Additional configs
├── postgres/             # PostgreSQL configs (optional)
└── volumes/              # Persistent data (git-ignored)
    ├── postgres/        # Database files
    ├── redis/          # Cache data
    ├── pgadmin/        # pgAdmin settings
    └── uploads/        # User uploads

Container Architecture

  • Runtime-only configuration: No build configs in docker-compose.yml
  • Pre-built images: Build images separately before deployment
  • Bind mount volumes: Easy backup and data management
  • Service orchestration: All services managed through Docker Compose
  • Nginx reverse proxy: Routes traffic to appropriate services

Development Workflow

  1. Build Docker images for frontend and backend
  2. Use docker-compose.yml for runtime orchestration
  3. All persistent data stored in docker/volumes/
  4. Volume backups handled through tar archives
  5. Easy restoration from backup files
