Question

我正在尝试在kubernetes集群中部署nginx普罗米修斯导出器（https://github.com/nginxinc/nginx-prometheus-exporter），但是如果在args标记中使用参数“ -nginx.scrape-uri”，它将失败。如果我将其删除，则可以使用，但使用默认值“ 127.0.0.1:8080”

我应该如何传递此参数？

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

这里是它引发的错误

  -nginx.scrape-uri string
        A URI or unix domain socket path for scraping NGINX or NGINX Plus metrics.
        For NGINX, the stub_status page must be available through the URI. For NGINX Plus -- the API. The default value can be overwritten by SCRAPE_URI environment variable. (default "http://127.0.0.1:8080/stub_status")

尝试一下：

    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"

提供的标志，但未在nginx prometheus导出器中定义
