- 获取密码

[root@master ~]# kubectl get secret op-grafana -n kube-monitor -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
prom-operator

NodPort 方式暴露

# Gafana 暴露
[root@master ~]# kubectl edit svc op-grafana -n kube-monitor
service/op-grafana edited
[root@master ~]# kubectl get svc op-grafana -n kube-monitor -o yaml |grep -i nodeport
    nodePort: 30300     # 自定义暴露端口,默认随机
  type: NodePort        # 类型模式

# Prometheus 暴露
[root@master ~]# kubectl edit svc op-kube-prometheus-stack-prometheus -n kube-monitor
service/op-kube-prometheus-stack-prometheus edited
[root@master ~]# kubectl get svc op-kube-prometheus-stack-prometheus -n kube-monitor -o yaml |grep -i nodeport
    nodePort: 30301
    nodePort: 31177
  type: NodePort

Ingress-nginx 方式

• 略

使用local pv持久化存储数据

参考: Helm 安装prometheus-stack 使用local pv持久化存储数据-CSDN博客

多节点存储持久化

• 去除节点亲和性即可

其他方式

• influxdb存储prometheus数据

• mysql存储grafana数据
