Question

我在我的应用中添加了端点/metrics 这是我为prometheus编写的配置文件

kind: ConfigMap
metadata:
  name: prometheus-config
apiVersion: v1
data:
  prometheus.yml: |-
    global:
      scrape_interval: 5s
      evaluation_interval: 5s
    scrape_configs:
    - job_name: 'goserver'
      scheme: http
      tls_config:
        ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
      bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
      kubernetes_sd_configs:
      - api_server: https://kubernets.default.svc
        role: pod
      relabel_configs:
      - source_labels: [__meta_kubernetes_pod_label_app]
        regex: goserver
        action: keep
      - source_labels: [__meta_kubernetes_pod_name]
        target_label: k8s_pod
        action: replace

以下是部署文件

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: prometheus-deployment
spec:
  replicas: 1
  template:
  metadata:
    labels:
      app: prometheus-server
  spec:
    containers:
    - name: prometheus
      image: prom/prometheus:latest
      args:
        - "-config.file=/etc/prometheus/conf/prometheus.yml"
        # Metrics are stored in an emptyDir volume which
        # exists as long as the Pod is running on that Node.
        # The data in an emptyDir volume is safe across container crashes.
        - "-storage.local.path=/prometheus"
      ports:
        - containerPort: 9090
      volumeMounts:
        - name: prometheus-server-volume
          mountPath: /etc/prometheus/conf
        - name: prometheus-storage-volume
          mountPath: /prometheus
  volumes:
    - name: prometheus-server-volume
      configMap:
        name: prometheus-config
    - name: prometheus-storage-volume
      emptyDir: {} # containers in the Pod can all read and write the same files here.

这是应用程序的部署文件

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: server-deployment
  namespace: default
spec:
  replicas: 1
  template:
    metadata:
      labels:
         app: goserver
    spec:
      containers:
      - name: goserver
        imagePullPolicy: Always
        image: utkarshmani1997/goserver:v1.4
        ports:
        - containerPort: 8080

我已经在NodePort类型的端口32514和32520上创建了prometheus和goserver的服务。这与minikube一起正常工作，并从我的应用程序中删除指标但不使用虚拟框中的kubeadm设置（多节点集群）。为了获得kubernetes的指标，我必须做出哪些改变。我尝试在rbac-setup.yaml和prometheus-kubernetes.yaml中进行一些更改，但它无效。

我正在通过群集外部的ssh -NL 1234：localhost：32514访问浏览器，因为vagrant box没有ubuntu桌面ui。

Answer 1

我发现了这个问题，实际上这个问题与rbac有关。我没有在部署文件中添加serviceAccountName。现在它正在顺利进行新的改变。

prometheus并没有从kubernetes上部署的应用程序中删除指标
