+# Cloudflare DDNS Updater con UI
+
+Sistema automatico per aggiornare i record DNS di Cloudflare con il tuo IP pubblico dinamico, completo di interfaccia web per monitoraggio.
+
+## Caratteristiche
+
+- ✅ Aggiornamento automatico DNS tramite container `oznu/cloudflare-ddns`
+- ✅ Interfaccia web Flask per monitoraggio in tempo reale
+- ✅ Auto-refresh AJAX senza ricaricare la pagina
+- ✅ Visualizzazione stato di sincronizzazione IP
+- ✅ Cache intelligente per ridurre chiamate API
+- ✅ Health check e logging strutturato
+- ✅ Design responsive dark mode
+
+## Requisiti
+
+- Docker e Docker Compose
+- Token API Cloudflare con permessi DNS edit
+- Zona DNS configurata su Cloudflare
+
+## Configurazione
+
+1. Crea il file `.env` nella root del progetto:
+
+```env
+# Cloudflare
+CF_API_TOKEN=your_cloudflare_api_token
+CF_ZONE=tuodomain.it
+CF_SUBDOMAIN=subdomain
+CF_PROXIED=false
+CF_TTL=120
+
+# Frequenza controllo IP (cron syntax)
+CF_CRON=*/5 * * * *
+
+# Configurazione Container
+DATA_VOLUME=./data
+RESTART_POLICY=unless-stopped
+
+# UI Settings
+UI_REFRESH_SECONDS=60
+UI_PORT=8088
+```
+
+2. Avvia i container:
+
+```bash
+docker-compose up -d
+```
+
+3. Accedi all'interfaccia web:
+
+```
+http://localhost:8088
+```
+
+## Struttura Progetto
+
+```
+.
+├── docker-compose.yml      # Configurazione Docker
+├── .env                    # Variabili ambiente (gitignored)
+├── ui/
+│   ├── app.py             # Server Flask
+│   ├── cloudflare.py      # API Cloudflare
+│   ├── requirements.txt   # Dipendenze Python
+│   └── templates/
+│       └── index.html     # UI web
+└── data/                  # Dati persistenti (gitignored)
+```
+
+## API Endpoints
+
+- `GET /` - Interfaccia web
+- `GET /api/records` - JSON con stato record DNS
+- `GET /health` - Health check
+
+## Monitoraggio
+
+L'interfaccia mostra per ogni record:
+- Nome FQDN
+- IP configurato nel DNS
+- IP pubblico attuale
+- Stato Proxy Cloudflare
+- Stato sincronizzazione (OK/MISMATCH/ERROR)
+- Ultimo aggiornamento
+
+## Ottimizzazioni
+
+- ✅ Cache Zone ID per evitare chiamate ripetute
+- ✅ Timeout su tutte le richieste HTTP
+- ✅ Validazione configurazione all'avvio
+- ✅ CORS abilitato per integrazioni esterne
+- ✅ Auto-refresh AJAX senza refresh completo
+- ✅ Gestione errori e logging strutturato
+
+## Troubleshooting
+
+Verifica i log dei container:
+
+```bash
+docker-compose logs cloudflare-ddns
+docker-compose logs cloudflare-ddns-ui
+```
+
+Verifica l'health status:
+
+```bash
+curl http://localhost:8088/health
+```
+

+
+MIT
