NAME                        	CHART VERSION	APP VERSION	DESCRIPTION

先将loki 拉取下来
#helm pull grafana/loki-stack
# tar xf loki-stack-2.10.2.tgz && cd loki-stack
使用制备器创建pv
#cat loki-values.yaml 
loki:
  enabled: true
  persistence:
    enabled: true
    storageClassName: managed-nfs-storage 
    accessModes:
      - ReadWriteOnce
    size: 1Gi

promtail:
  enabled: true

grafana:
  enabled: true
  adminPassword: admin  # 修改为你自己的密码
  service:
    type: NodePort       # 如果是外部访问，可以使用 NodePort
    port: 80
  persistence:
    enabled: true
    storageClassName: managed-nfs-storage
    accessModes:
      - ReadWriteOnce
    size: 1Gi

  
  
# helm install loki ./loki-stack -n loki -f ./loki-stack/loki-values.yaml
