# Install Glance (dashboard) di VPS Hariri — satu perintah:

# Yang dilakukan script ini:
#   1. Cek internet keluar + Docker
#   2. Unduh glance.yml ke /opt/glance
#   3. Jalankan container Glance (port 8080, --network host)
#   4. Verifikasi Glance menjawab di :8080
# Perintah ini boleh diulang kapan saja (container lama diganti).
