k8s 1.21 prometheus监控 ingress-nginx
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
