+   - Console: 127.0.0.1:9001
+   - API: 127.0.0.1:9000
+   - Volume: minio-data

+   - Volume: test-data
+   - For volume verification
+
+**Volumes (3 total):**
+- minio-data - MinIO object storage
+- db-data - PostgreSQL data
+- test-data - Test container data
+
+## Technical Implementation
+
+### Storage Parallels
+- Docker named volumes → AWS EBS volumes
+- MinIO → AWS S3 (100% API compatible)
+- Volume lifecycle management
+
+### INF-04 Compliance
+- All data stored in named volumes
+- Data persists across container restart
+- Data persists across container removal (with -v flag)
+- Verified with persistence tests
+
+### MinIO Configuration
+- S3-compatible API (ports 9000/9001)
+- Default credentials for testing
+- Console UI for management
+- mc (MinIO Client) for CLI operations
+
+### Combined RED/GREEN Approach
+- Tests created first (RED phase)
+- Infrastructure implemented immediately (GREEN phase)
+- Documentation created during implementation
+- More efficient than separate phases
+
+## Requirements Covered
+
+- **LAB-04:** Docker volumes and MinIO S3-compatible storage
+- **INF-04:** Data persists across container lifecycle
+- **DOCT-01:** Tutorial with step-by-step guide
+- **DOCT-02:** How-to guide for volume management
+- **DOCT-03:** Reference documentation for syntax
+- **DOCT-04:** Explanation with storage↔S3 parallels
+- **PARA-01:** Docker volumes mapped to EBS, MinIO to S3
+
+## Deviations from Plan
+
+**Combined Approach:**
+- Plan specified combined RED/GREEN for efficiency
+- Successfully executed tests + implementation together
+- More efficient than separate phases
+- Documentation created during implementation
+
+**Dockerfile Not Created:**
+- MinIO and PostgreSQL use official images
+- No custom Dockerfile needed
+- Deviation accepted for efficiency
+
+## Issues Encountered
+
+None - combined approach executed successfully without issues.
+
+## Next Phase Readiness
+
+- Lab 04 complete and ready for student use
+- Storage concepts established with clear cloud parallels
+- Foundation laid for Lab 05 (Database & RDS)
+- Named volumes and persistence patterns established
+
+The implementation successfully demonstrates Docker volumes as a local simulation of cloud storage concepts, with MinIO providing S3-compatible object storage and clear educational value for students learning cloud storage.

+- Verify network isolation
+
+## 2. Security Compliance (02-security-compliance-test.sh)

+- INF-03: All containers have resource limits (Lab 03, 05)
+- INF-04: Data persists in named volumes (Lab 04, 05)
+
+## 3. Architecture Validation (03-architecture-validation-test.sh)
+- Multi-tier architecture: web → app → db → storage
+- Proper network segmentation
+- Resource allocation per tier
+- Data flow verification
+
+## 4. Final Integration (99-final-integration-test.sh)

+# Troubleshooting - Guida Risoluzione Problemi
+
+Questo documento copre i problemi più comuni che possono verificarsi durante i laboratori.
+
+## Problemi Generali Docker
+
+### Container non parte
+
+**Sintomo:** `docker compose up` fallisce con errori
+
+**Soluzioni:**
+```bash
+# Verifica Docker sia in esecuzione
+docker ps
+
+# Verifica logs del container
+docker logs <container-name>
+
+# Verifica non ci siano conflitti di porte
+docker ps
+netstat -tuln | grep <porta>
+```
+
+### Permesso negato
+
+**Sintomo:** `permission denied` o `Got permission denied`
+
+**Soluzioni:**
+```bash
+# Aggiungi utente al gruppo docker
+sudo usermod -aG docker $USER
+
+# Logout e login, oppure:
+newgrp docker
+
+# Verifica appartenenza al gruppo
+groups $USER
+```
+
+### Porta già in uso
+
+**Sintomo:** `port is already allocated`
+
+**Soluzioni:**
+```bash
+# Trova processo usando la porta
+sudo lsof -i :<porta>
+sudo netstat -tulpn | grep <porta>
+
+# Ferma il servizio che usa la porta
+sudo systemctl stop <servizio>
+
+# Oppure cambia porta nel docker-compose.yml
+ports:
+  - "127.0.0.1:8081:80"  # Usa porta diversa
+```
+
+## Lab-Specifici
+
+### Lab 01 - IAM & Sicurezza
+
+#### Container gira come root
+
+**Verifica:**
+```bash
+docker exec lab01-<container> whoami
+```
+
+**Soluzione:** Il Dockerfile deve creare un utente non-root.
+
+#### Utente non può accedere a Docker
+
+**Sintomo:** `permission denied while trying to connect`
+
+**Verifica:**
+```bash
+groups <utente>
+```
+
+**Soluzione:**
+```bash
+sudo usermod -aG docker <utente>
+newgrp docker
+```
+
+### Lab 02 - Network & VPC
+
+#### Container non possono comunicare
+
+**Verifica:**
+```bash
+docker network inspect lab02-vpc-private
+docker network inspect lab02-vpc-public
+```
+
+**Soluzione:** Assicurati che i container siano nella stessa rete.
+
+#### Ping fallisce tra reti
+
+**Sintomo:** `ping: bad address` o `Network is unreachable`
+
+**Verifica:**
+```bash
+# Verifica IP assegnati
+docker inspect <container> | grep IPAddress
+```
+
+**Soluzione:** Le reti sono isolate per design. Usa container multi-homed per testare.
+
+### Lab 03 - Compute & EC2
+
+#### Healthcheck sempre unhealthy
+
+**Verifica:**
+```bash
+docker inspect <container> --format '{{.State.Health}}'
+```
+
+**Soluzione:** Verifica il comando healthcheck e la configurazione del servizio.
+
+#### Resource limits non applicati
+
+**Verifica:**
+```bash
+docker stats
+docker inspect <container> --format '{{.HostConfig.Memory}}'
+```
+
+**Soluzione:** Assicurati che `deploy.resources` sia configurato in docker-compose.yml.
+
+### Lab 04 - Storage & S3
+
+#### Dati persi dopo riavvio
+
+**Verifica:**
+```bash
+docker volume ls
+docker volume inspect <volume>
+```
+
+**Soluzione:** Assicurati di usare volumi nominativi, non bind mount anonimi.
+
+#### MinIO non accessibile
+
+**Verifica:**
+```bash
+curl http://localhost:9000/minio/health/live
+```
+
+**Soluzione:** Verifica che MinIO sia in esecuzione e che le porte siano corrette.
+
+### Lab 05 - Database & RDS
+
+#### Database non accessibile
+
+**Verifica:**
+```bash
+docker exec lab05-db pg_isready -U lab05_user
+```
+
+**Soluzione:** Il database è in rete privata. Usa container app per connetterti:
+```bash
+docker exec lab05-app psql -h db -U lab05_user -d lab05_db
+```
+
+#### Connessione dal host fallisce
+
+**Sintomo:** `connection refused`
+
+**Soluzione:** CORRETTO! Il database non deve essere accessibile dall'host (INF-02).
+
+## Comandi Utili
+
+### Pulizia completa
+
+```bash
+# Ferma tutti i container
+docker compose down
+
+# Rimuovi volumi (ATTENZIONE: perdita dati!)
+docker compose down -v
+
+# Rimuovi reti non usate
+docker network prune
+
+# Rimuovi container stopped
+docker container prune
+
+# Reset completo
+./scripts/reset-env.sh
+```
+
+### Diagnostica
+
+```bash
+# Verifica risorse
+docker stats
+
+# Verifica eventi
+docker events
+
+# Ispeziona container
+docker inspect <container>
+
+# Verifica reti
+docker network ls
+docker network inspect <network>
+
+# Verifica volumi
+docker volume ls
+docker volume inspect <volume>
+```
+
+## Quando Chiedere Aiuto
+
+Prima di chiedere:
+
+1. ✅ Cerca nei tutorial del lab
+2. ✅ Controlla troubleshooting del lab specifico
+3. ✅ Esegui i test per identificare il problema
+4. ✅ Verifica i log dei container
+
+Se il problema persiste:
+
+- Apri una issue su GitHub
+- Includi: errore completo, passi per riprodurre, ambiente
+- Specifica: OS, Docker version, lab specifico
+
+---
+
+**Nota:** La maggior parte dei problemi sono risolvibili verificando i log e assicurandosi che i prerequisiti siano soddisfatti.
