## 部署 Heapster 插件

官方github下载地址需要新版可以去下

创建所需yaml文件

cd /data/src
wget https://github.com/kubernetes/heapster/archive/v1.4.3.tar.gz
tar zxvf v1.4.3.tar.gz

cd heapster-1.4.3/deploy/kube-config/influxdb

[root@node influxdb]# pwd
/data/src/heapster-1.4.3/deploy/kube-config/influxdb
ls 
grafana.yaml  heapster.yaml  influxdb.yaml

get一下svc看一下端口

[root@node influxdb]# kubectl get svc --all-namespaces  
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE  
kube-system heapster ClusterIP 10.0.0.51  80/TCP 4h7m  
kube-system kube-dns ClusterIP 10.0.0.2  53/UDP,53/TCP 4h32m  
kube-system kubernetes-dashboard ClusterIP 10.0.0.233  443/TCP 5d23h  
kube-system monitoring-grafana NodePort 10.0.0.111  80:44137/TCP 4h7m  
kube-system monitoring-influxdb ClusterIP 10.0.0.132  8086/TCP 4h7m  

可以看到端口是44137 我们可以单独访问grafana https://10.167.130.205:44137
