在 nginx prometheus 导出器中提供但未定义的标志

Question

我正在尝试在 kubernetes 集群中部署一个 nginx prometheus 导出器 (https://github.com/nginxinc/nginx-prometheus-exporter)，但是如果我在 args 标记中使用参数“-nginx.scrape-uri”，它会失败。如果我删除它，那么它可以工作，但使用默认值“127.0.0.1:8080”

我应该如何传递这个参数？

这是我的 deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-prometheus-exporter
  namespace: monitoring
  labels:
    k8s-app: nginx-prometheus-exporter
spec:
  selector:
    matchLabels:
      k8s-app: nginx-prometheus-exporter
  template:
    metadata:
      labels:
        k8s-app: nginx-prometheus-exporter
      annotations:
        prometheus.io/path: "/metrics"
        prometheus.io/port: "9113"
        prometheus.io/scrape: "true"
    spec:
      containers:
      - name: nginx-prometheus-exporter
        image: infra-harbor-paas.attmx-ne.local/matrixx_lab01/nginx/nginx-prometheus-exporter:0.8.0
        args: ["-nginx.scrape-uri http://10.150.152.206:8080/stub_status"]
        ports:
        - containerPort: 9113
          name: http
      imagePullSecrets:
        - name: regcred

这里是它抛出的错误

试试这个：

    spec:
      containers:
      - name: nginx-prometheus-exporter
        image: infra-harbor-paas.attmx-ne.local/matrixx_lab01/nginx/nginx-prometheus-exporter:0.8.0
        args: 
        - "-nginx.scrape-uri=http://10.150.152.206:8080/stub_status"
