# Node Exporter - Prometheus metrics exporter for hardware/OS metrics
# Exposes metrics on port 9101 (changed from 9100 due to host conflict)
# Used by: Grafana/Prometheus monitoring stack
# Note: Using bridge network with port mapping instead of host network
#       to avoid conflict with host-installed node_exporter
