k8s 1.21 prometheus监控 ingress-nginx

1. k8s 部署 ingress-nginx

# 关键代码 controller-service.yaml
metadata:
  annotations:
    # 添加如下两行代码
    prometheus.io/port: "10254"
    prometheus.io/scrape: "true"

spec:
  type: NodePort
  ports:
    # 添加如下三行代码
    - name: prometheus
      port: 10254
      targetPort: prometheus
      

# controller-deployment.yaml 我采用 DaemonSet里面的
apiVersion: apps/v1
kind: DaemonSet

# 在 ports 添加 - name: prometheus  containerPort: 10254
ports:
  - name: prometheus 
    containerPort: 10254

完整的ingress-nginx, 最好在某node 节点 添加标签， app: ingress ，这样就会部署到指定的节点，这样就能用节点的ip，不然当你重新部署 ingress-nginx 后，不知又落在哪个节点上
