Kubernetes Monitoring Stack

Kompletní monitoring pro Kubernetes. Prometheus, Grafana, alerting.

Stack

Standard: Prometheus (metriky) + Grafana (vizualizace) + Alertmanager (alerty).

Instalace

# kube-prometheus-stack Helm chart
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm install monitoring prometheus-community/kube-prometheus-stack \
  --namespace monitoring --create-namespace \
  --set grafana.adminPassword=admin

ServiceMonitor

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: myapp
spec:
  selector:
    matchLabels: {app: myapp}
  endpoints:
    - port: metrics
      path: /metrics
      interval: 15s

Shrnutí

kube-prometheus-stack = one-click monitoring. Přidejte /metrics endpoint do aplikací a ServiceMonitor pro scraping.
