# Prometheus + Grafana Monitoring Stack - LIVE DEPLOYMENT
# =============================================================================
# This is the actual running compose at /home/homelab/docker/monitoring/
# Deployed directly with docker compose, NOT via Portainer.
#
# Config files are bind-mounted from the same directory:
#   ./prometheus/prometheus.yml   - scrape config + alerting rules reference
#   ./prometheus/alert-rules.yml  - alerting rules
#   ./grafana/provisioning/       - datasources + dashboard provisioning
#
# To redeploy: docker compose -f this file up -d  (from /home/homelab/docker/monitoring/)
# To reload Prometheus config without restart: curl -X POST http://localhost:9090/-/reload
#
# See monitoring.yaml for the self-contained Portainer GitOps version (embedded configs).
# =============================================================================
