今天主要分享下，在 k8s 集群下，微服务的各种状态指标情况的监控，我们都知道Prometheus是做数据监控的，但说白点，其独特格式的数据，其实都是靠一些源来的，那么这些源有哪些呢？已经有了cadvisor、heapster、metric-server，几乎容器运行的所有指标都能拿到，但是下面这种情况却无能为力：

调度了N个replicas？现在可用的有 N 个？
N 个 Pod 是 running/stopped/terminated 状态？
Pod 重启了N次？
我有 N 个job在运行中

而这些则是 kube-state-metrics 提供的内容，它基于client-go开发，轮询Kubernetes API，并将Kubernetes的结构化信息转换为metrics。kube-state-metrics是kubernetes开源的一个插件。


废话不多说，直接上教程。。。

部署教程

下载
  1. 在官网 kube-state-metrics 下载相应的源码以及部署脚本，本次使用release1.9.7，即v1.9.7版本的 kube-state-metrics

  1. 执行 cd /kube-state-metrics/examples/standard，可以看到几个文件：

3
4

6
cluster-role-binding.yaml
cluster-role.yaml
deployment.yaml
prometheus-configmap.yaml
service-account.yaml
service.yaml

如果Prometheus已经部署，且部署在kube-system空间下，则源码中的namespace不需更改，否则可自定义为monitoring。

更新
  1. 首先修改 service.yaml

apiVersion: v1
kind: Service
metadata:
  annotations:
    prometheus.io/scrape: "true"
  labels:
    app.kubernetes.io/name: kube-state-metrics
    app.kubernetes.io/version: v1.9.7
  name: kube-state-metrics
  namespace: kube-system
spec:
  clusterIP: None
  ports:
  - name: http-metrics
    port: 8080
    targetPort: http-metrics
  - name: telemetry
    port: 8081
    targetPort: telemetry
  selector:
    app.kubernetes.io/name: kube-state-metrics

很简单，增加了注解方便后面使用


坑：源码中的角色授权绑定的是其写的kind为ClusterRole的资源，但后来发现部署kube-state-metrics服务时，其无法成功访问k8s的api-server，故需要修改，弃用其ClusterRole，使用k8s系统最高权限cluster-admin。


  1. 更改访问权限

vi cluster-role-binding.yaml

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  labels:
    app.kubernetes.io/name: kube-state-metrics
    app.kubernetes.io/version: v1.9.7
  name: kube-state-metrics
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin #kube-state-metrics
subjects:
- kind: ServiceAccount
  name: kube-state-metrics
  namespace: kube-system

部署

cd /kube-state-metrics/examples/standard
kubectl create -f .

此时还需要更新Prometheus的挂载的configMap，因为前面说了只抓取带有prometheus.io/scrape: “true”注解的endpoint


vi prometheus-configmap.yaml

更新 configmap 后，需要重启 Prometheus 使其生效，如果没部署，则创建 configmap 后执行脚本部署即可。
