Deployment Architecture

DocuPulse is designed for containerized deployment using Docker and Docker Compose, providing a scalable, production-ready infrastructure. The system supports both single-instance deployments and multi-tenant orchestration with automated provisioning and health monitoring.

Docker Architecture
Web Application
  • • Flask application container
  • • Gunicorn WSGI server
  • • Health check endpoints
  • • Resource limits & monitoring
  • • Volume mounts for uploads
  • • Environment configuration
Database
  • • PostgreSQL 13 container
  • • Persistent volume storage
  • • Connection pooling
  • • Health monitoring
  • • Automated backups
  • • Performance optimization
Docker Compose Configuration
Services Configuration
Web Service
  • • Image: Custom Flask application
  • • Port: 5000 (internal) / ${PORT} (external)
  • • Environment: Production settings
  • • Volumes: Upload storage
  • • Dependencies: Database service
  • • Health checks: HTTP endpoint
Database Service
  • • Image: postgres:13
  • • Port: 5432 (internal only)
  • • Environment: Database credentials
  • • Volumes: Persistent data storage
  • • Health checks: pg_isready
  • • Restart policy: unless-stopped
Multi-Tenant Deployment
Master Instance
  • • Central orchestration hub
  • • Instance management dashboard
  • • Automated deployment via API
  • • Health monitoring & alerts
  • • Resource allocation tracking
  • • Backup & recovery management
Tenant Instances
  • • Isolated Docker networks
  • • Separate database instances
  • • Unique port assignments
  • • Independent volume storage
  • • Custom domain routing
  • • Scalable resource limits
Deployment Process
Single Instance Deployment

Deployment Steps
  1. Clone repository
  2. Configure environment
  3. Run database migrations
  4. Start Docker services
  5. Verify health checks
  6. Configure reverse proxy
Multi-Tenant Deployment
Infrastructure Requirements
  • • Portainer for container management
  • • NGINX Proxy Manager
  • • Git repository access
  • • SSL certificate provider
  • • Monitoring & logging
Automated Process
