[Emeka000]

Description:

This PR introduces a complete Docker-based deployment setup for the hospital management system, focused on security, reliability, and observability.

Key Changes:

✅ Created a multi-stage Dockerfile to optimize image size and security for the medical system.

⚙️ Configured docker-compose to orchestrate:

    The medical application

    PostgreSQL with data encryption (at rest and in transit)

    Redis for session management

    Backup and recovery containers

    Monitoring stack (e.g., Prometheus, Grafana, Alertmanager)

🔐 Enabled PostgreSQL encryption using SSL and data-at-rest encryption mechanisms.

🔁 Set up automated backup & recovery containers with test validation.

📈 Integrated monitoring tools with custom alerts tailored for medical-grade system reliability.

Acceptance Criteria Met:

✅ Hospital system runs reliably in Docker

✅ All medical data is encrypted at rest and in transit

✅ Backup systems are automated and tested

✅ Monitoring stack provides medical-grade alerting
