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

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: endpointsrelabel_configs:- action: keepregex: ingress-nginx;ingress-nginx-controller;metricssource_labels:- __meta_kubernetes_namespace- __meta_kubernetes_service_name- __meta_kubernetes_endpoint_port_namescheme: http

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

apiVersion: v1
kind: Service
...
spec:ports:- appProtocol: httpname: httpport: 80protocol: TCPtargetPort: http- appProtocol: httpsname: httpsport: 443protocol: TCPtargetPort: https- name: metricsport: 10254targetPort: 10254...

然后重新apply一下使其ingress-controller生效

完成开启10254端口后就可以在prometheus上看到监控的ingress-nginx目标了

三、grafana添加ingress-nginx controller的监控模版
