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

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 <none> 80/TCP 4h7m
kube-system kube-dns ClusterIP 10.0.0.2 <none> 53/UDP,53/TCP 4h32m
kube-system kubernetes-dashboard ClusterIP 10.0.0.233 <none> 443/TCP 5d23h
kube-system monitoring-grafana NodePort 10.0.0.111 <none> 80:44137/TCP 4h7m
kube-system monitoring-influxdb ClusterIP 10.0.0.132 <none> 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
