如何安装kube-state-metrics

Question

我想收集K8s中POD的指标。kube-state-metrics看起来不错。我无法按照README进行操作。我追了make container。有没有简单的方法来部署kube-state-metrics。

冉kubectl apply -f kubernetes。摆脱错误。我认为版本不匹配。任何想法如何克服？

你近了

同一页面上有一个Kubernetes Deployment部分。

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

克隆github存储库后，即可简单运行：

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

如果您运行的是K8s的较旧版本，但仍使用部署版本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:
