所有 Kubernetes 代理目标关闭 - Prometheus Operator

Question

我在openstack中部署了一个k8s集群。我已经为它部署了 Prometheus operator 来监控集群。但是我收到了所有节点的 Kubernetes 代理关闭警报。

我想了解 Prometheus 算子如何抓取 Kubernetes 代理的基础知识？还想知道需要做哪些配置来修复它。

我可以看到 kube 代理在 10249 端口的所有节点中都是运行。

错误：

Get http://10.8.10.11:10249/metrics: dial tcp 10.8.10.11:10249: connect: connection refused

HELM 值配置

kubeProxy:
  enabled: true

  ## If your kube proxy is not deployed as a pod, specify IPs it can be found on
  ##
  endpoints: []
  # - 10.141.4.22
  # - 10.141.4.23
  # - 10.141.4.24

  service:
    port: 10249
    targetPort: 10249
    # selector:
    #   k8s-app: kube-proxy

  serviceMonitor:
    ## Scrape interval. If not set, the Prometheus default scrape interval is used.
    ##
    interval: ""

    ## Enable scraping kube-proxy over https.
    ## Requires proper certs (not self-signed) and delegated authentication/authorization checks
    ##
    https: false

Answer 1

为 metric-bind-address 设置 kube-proxy 参数

$ kubectl edit cm/kube-proxy -n kube-system

...
kind: KubeProxyConfiguration
metricsBindAddress: 0.0.0.0:10249
...

$ kubectl delete pod -l k8s-app=kube-proxy -n kube-system
