如何安装 kube-state-metrics

Question

我想在 K8s 中收集 PODs 的指标。 kube-state-metrics 看起来不错。我无法关注 README。我在 make container 之后击中了。有什么简单的方法可以部署kube-state-metrics。

运行kubectl apply -f kubernetes。出现以下错误。我认为，版本不匹配。知道如何克服吗？

serviceaccount "kube-state-metrics" configured
service "kube-state-metrics" configured
Error from server (BadRequest): error when creating "kubernetes/kube-state-metrics-cluster-role-binding.yaml": ClusterRoleBinding in version "v1" cannot be handled as a ClusterRoleBinding: no kind "ClusterRoleBinding" is registered for version "rbac.authorization.k8s.io/v1"

你很接近。

同一页面有一个 Kubernetes Deployment 部分。

https://github.com/kubernetes/kube-state-metrics#kubernetes-deployment

克隆 github 存储库后，您只需运行:

kubectl apply -f kubernetes

您可以在此处仔细查看部署文件：

https://github.com/kubernetes/kube-state-metrics/tree/master/kubernetes

---更新---

如果您运行使用旧版本的 K8s，它仍然使用部署版本 v1beta1 并且没有 RBAC，请尝试以下（yaml 文件）示例：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: kube-state-metrics-deployment
spec:
  replicas: 1
  template:
    metadata:
      labels:
        k8s-app: kube-state-metrics
        version: "v0.4.1"
    spec:
      containers:
      - name: kube-state-metrics
        image: gcr.io/google_containers/kube-state-metrics:v0.4.1
        ports:
        - containerPort: 8080
---
apiVersion: v1
kind: Service
metadata:
  annotations:
    prometheus.io/scrape: 'true'
  name: kube-state-metrics
  labels:
    k8s-app: kube-state-metrics
spec:
  ports:
  - name: http-metrics
    port: 8080
    protocol: TCP
  selector:
    k8s-app: kube-state-metrics

对于 UPDATE1 中的那些错误（在我的问题中），我在那个 repo 中使用了以前版本的 yaml 文件。你可以在这里看到变化 --> https://github.com/kubernetes/kube-state-metrics/commit/24ab2b6e6d7d97690538cabc977c4afc3dcdc822
