# ============================================================
# Docker Compose - S3 to Local Mirror + Web Dashboard
# ============================================================
# Servizio che sincronizza un bucket S3-compatibile (RustFS, MinIO, etc.)
# verso una cartella locale montata come volume.
# Include una dashboard web in tempo reale (stile Syncthing).
#
# Uso:
#   1. Configurare il file .env con i parametri del bucket
#   2. docker compose up -d
#   3. Aprire http://localhost:8080 per la dashboard
#   4. I file appariranno nella cartella definita da LOCAL_SYNC_PATH
# ============================================================
