--set grafana.persistence.storageClassName=local-storage

helm install kube-prometheus-stack \
  --create-namespace \
  --namespace kube-prometheus-stack \
  prometheus-community/kube-prometheus-stack \
  --set prometheus.prometheusSpec.storageSpec.volumeClaimTemplate.spec.resources.requests.storage=4Gi \
  --set grafana.persistence.enabled=true \
  --set grafana.persistence.type=pvc \
  --set grafana.persistence.size=2Gi \
  --set "grafana.adminPassword=kube#1234"

metadata:
  name: grafana-kube
spec:
  parentRefs:
