更改访问方式

# kubectl edit -n monitoring service prometheus-k8s
# kubectl edit -n monitoring service grafana
# kubectl edit -n monitoring service alertmanager-main
分别修改service prometheus-k8s、grafana和alertmanager-main,service类型为NodePort,端口分别为30021、30022、30023。
比如,在port: 9090下新增一行nodePort: 30021,将type: 后面的值修改成NodePort
