1、部署准备
说明：所有的容器组都运行在monitoring 命名空间
本文参考https://github.com/coreos/kube-prometheus
由于官方维护的版本在现有的部署环境出现问题所以下面做了一些修改及变更不影响整体效果
prometheus yaml 会做一些小的更改，grafana 不使用官方yaml 2、prometheus 服务相关yaml 准备
2.1、下载官方yaml
mkdir kube-prometheus
cd kube-prometheus
git clone https://github.com/coreos/kube-prometheus
cd kube-prometheus/manifests
mkdir prometheus-prometheus
mv prometheus-clusterRoleBinding.yaml prometheus-prometheus
mv prometheus-clusterRole.yaml prometheus-prometheus
mv prometheus-prometheus.yaml prometheus-prometheus
mv prometheus-roleBindingConfig.yaml prometheus-prometheus
mv prometheus-roleBindingSpecificNamespaces.yaml prometheus-prometheus
mv prometheus-roleConfig.yaml prometheus-prometheus
mv prometheus-roleSpecificNamespaces.yaml prometheus-prometheus
mv prometheus-rules.yaml prometheus-prometheus
mv prometheus-serviceAccount.yaml prometheus-prometheus
mv prometheus-serviceMonitor.yaml prometheus-prometheus
mv prometheus-service.yaml prometheus-prometheus
mkdir prometheus-monitor # 以后所有系统业务的监控yaml 放到此文件夹
mv prometheus-serviceMonitorApiserver.yaml prometheus-monitor
mv prometheus-serviceMonitorCoreDNS.yaml prometheus-monitor
mv prometheus-serviceMonitorKubeControllerManager.yaml prometheus-monitor
mv prometheus-serviceMonitorKubelet.yaml prometheus-monitor
mv prometheus-serviceMonitorKubeScheduler.yaml prometheus-monitor2.2、创建监控etcd secret
etcd 监控要用到证书同时需要修改prometheus-prometheus.yaml 不如先创建修改好，以后就不用那么麻烦了
cd /apps/work/k8s/cfssl/pki/etcd/
监控etcd 生成配置etcd-certs
kubectl -n monitoring create secret generic etcd-certs --from-file=etcd-ca.pem --from-file=etcd_client-key.pem --from-file=etcd_client.pem2.3、修改prometheus-prometheus.yaml
cd /apps/work/k8s/kube-prometheus/manifests/prometheus-prometheus

kubectl apply -f .3.7 查看 grafana 状态
[root@jenkins prometheus-monitor]# kubectl get service -n monitoring -o wide | grep grafana
grafana NodePort 10.64.76.72 <none> 3000:30091/TCP 53d app=grafana,component=core

http://10.64.76.72:3000

或者Node ip 加端口30091 访问
配置 grafana heapster 监控访问数据 InfluxDB

4、导入grafana dashboards 文件
mkdir dashboards
cd dashboards
下载json 文件到此文件夹
我收集的一些
https://github.com/qist/kubernetes-monitor/tree/master/prometheus/grafana/dashboards
kubectl create configmap "grafana-import-dashboards" --from-file=dashboards/ --namespace=monitoring创建导入dashboards job

configMap:

kubectl apply -f grafana-job.yaml等待job 执行完成
打开grafana
查看Prometheus 数据库是否配置成功
界面是否有dashboards 
如果有这样的数据证明就上传成功
Kubernetes 有些展示可能还有一些问题 state-metrics 还没 部署完成下一篇部署完成展示就会正常
