Il database è in rete privata. Devi connetterti da container nella stessa rete:
```bash
# Prima entra in un container
docker exec -it lab05-app sh
# Poi connettiti
psql -h db -U lab05_user -d lab05_db
# Client temporaneo nella rete privata
docker run --rm -it --network lab05-vpc-private \
-e PGPASSWORD=lab05_password \
postgres:16-alpine \
psql -h db -U lab05_user -d lab05_db
```
Nota: il servizio `lab05-app` usa `nginx:alpine` e non include `psql`.
