配置prometheus从docker化的nodejs pod收集自定义指标。

Question

我已经建立了 prom-client（prometheus 的非官方客户端库）来收集我所需要的自定义指标。eks设置指南. 现在，我试图编辑默认的configmap来收集我的应用程序指标，但得到的错误。

parsing YAML file /etc/config/prometheus.yml: yaml: unmarshal errors:\n line 22: field cluster_ip not found in type kubernetes.plain\n line 25: cannot unmarshal !!str默认into []string

这是我根据docsprometheus.yaml配置图文件所做的。

apiVersion: v1
data:
  alerting_rules.yml: |
    {}
  alerts: |
    {}
  prometheus.yml: |
    global:
      evaluation_interval: 1m
      scrape_interval: 1m
      scrape_timeout: 10s
    rule_files:
    - /etc/config/recording_rules.yml
    - /etc/config/alerting_rules.yml
    - /etc/config/rules
    - /etc/config/alerts
    scrape_configs:
    ...DEFAULT CONFIGS...
    - job_name: my_metrics
      scrape_interval: 5m
      scrape_timeout: 10s
      honor_labels: true
      metrics_path: /api/metrics
      kubernetes_sd_configs:
        - role: service
          cluster_ip: 10.100.200.92
          namespaces:
            names:
              default
  recording_rules.yml: |
    {}
  rules: |
    {}
kind: ConfigMap
metadata:
  creationTimestamp: "2020-06-08T09:26:38Z"
  labels:
    app: prometheus
    chart: prometheus-11.3.0
    component: server

    release: prometheus

  namespace: prometheus
  uid: 8fadb17a-f5c5-4f9d-a931-fa1f77684847

这里的 clusterIP 是为我的服务分配的 IP，用于暴露部署。

我的deployment.yaml文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
spec:
  replicas: 2
  strategy:
    type: RollingUpdate
  selector:
    matchLabels:
      name: myapp
  template:
    metadata:
      labels:
        name: myapp
    spec:
      containers:
        - image: IMAGE_URL:BUILD_NUMBER
          name: myapp
          resources:
              limits:
                cpu: "1000m"
                memory: "2400Mi"
              requests:
                cpu: "500m"
                memory: "2000Mi"
          imagePullPolicy: IfNotPresent
          ports:
              - containerPort: 5000
                name: myapp

我的service.yaml文件暴露了部署的情况。

apiVersion: v1
kind: Service
metadata:
  name: myapp
spec:
  selector:
    deploy: staging
    name: myapp
  type: ClusterIP
  ports:
    - port: 80
      targetPort: 5000
      protocol: TCP

有没有一些不同的有效方法来针对我的应用进行指标收集，请告诉我。谅谅
