1. Prometheus setup (in cluster)

[ksobrenat32]

Helm install (baseline):

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update
helm install monitoring prometheus-community/kube-prometheus-stack \
  -n monitoring --create-namespace

This gives you:

• Prometheus (scraper + alerting rules engine)
• Alertmanager (sends notifications)
• Grafana (dashboards)
• node_exporter, kube-state-metrics (cluster baseline metrics)

👉 Research:

• Helm values for kube-prometheus-stack (so you can customize scrape configs, retention, resources).
• ServiceMonitor & PodMonitor CRDs (how they define scrape targets in Kubernetes).
• RBAC for Prometheus (to safely scrape external targets).
