一、prometheus中添加ingress-nginx的服务发现配置
二、ingress-nginx controller的service添加端口暴露监控指标
三、grafana添加ingress-nginx controller的监控模版

ingress-nginx默认是没有开启监控指标的，需要我们在ingress-nginx controller的svc里面开启10254端口来暴露监控指标然后进行抓取
在这里插入图片描述
ps：kubeadm方式和二进制方式部署的k8s集群都可以用此配置监控Ingress-Ningx Controller

一、prometheus中添加ingress-nginx的服务发现配置

prometheus部署链接：https://blog.csdn.net/qq_44930876/article/details/138163947

    - job_name: 'kubernetes-ingress-controller'
      kubernetes_sd_configs:
      - role: endpoints
      relabel_configs:
      - action: keep
        regex: ingress-nginx;ingress-nginx-controller;metrics
        source_labels:
        - __meta_kubernetes_namespace
        - __meta_kubernetes_service_name
        - __meta_kubernetes_endpoint_port_name
      scheme: http

二、ingress-nginx controller的service添加端口暴露监控指标

apiVersion: v1
kind: Service
...
spec:
  ports:
  - appProtocol: http
    name: http
    port: 80
    protocol: TCP
    targetPort: http
  - appProtocol: https
    name: https
    port: 443
    protocol: TCP
    targetPort: https
  - name: metrics
    port: 10254
    targetPort: 10254
    ...
