本节重点介绍 :

检查，kube-system ns

[root@prome-master01 prometheus]# kubectl get pod -n kube-system
NAME READY STATUS RESTARTS AGE
coredns-7d75679df-7f7tx 1/1 Running 0 88m
coredns-7d75679df-qmzbg 1/1 Running 0 88m
etcd-prome-master01 1/1 Running 0 88m
kube-apiserver-prome-master01 1/1 Running 0 88m
kube-controller-manager-prome-master01 1/1 Running 0 88m
kube-proxy-48dwz 1/1 Running 0 87m
kube-proxy-gmvvn 1/1 Running 0 88m
kube-scheduler-prome-master01 1/1 Running 0 88m
kube-state-metrics-647444dd74-h4tfk 1/1 Running 0 3m6s
prometheus-0 2/2 Running 0 87s

## 6. 使用node的ip:8091即可访问prometheus服务

```shell
curl localhost:8091

7. 排查问题

• 容器基础资源和node kubelet metrics采集报403错误，现象如下
• 
• 解决方案 rbac.yaml resource添加 node/metrics即可
• kube-scheduler和kube-controller-manager 采集报错，如下
• 
• 原因是因为 上述两个服务bind的地址是127.0.0.1 ,修改成0.0.0.0即可

• vim /etc/kubernetes/manifests/kube-scheduler.yaml
  vim /etc/kubernetes/manifests/kube-controller-manager.yaml 
  -bind-address=0.0.0.0 
  
  

最终的效果图

本节重点总结 :

• 准备好这些yaml文件
• 部署ksm
• 部署prometheus
