部署prometheus operator
git clone https://github.com/coreos/prometheus-operator
cd contrib/kube-prometheus/manifests/
kubectl apply -f .
出現問題：
NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE
daemonset.apps/prometheus-node-exporter 0 0 0 0 0 <none> 1h
原因：
在kube-system中有一個node-exporter ds， 其pod也是9100端口，導致端口衝突，這回阻止node exporter daemonset正確的部署pod。
解決方法：
刪掉kube-system中的node-exporter ds或者過修改node-exporter-daemonset.yaml中的端口 --upstream=http://127.0.0.1:9100/ ->--upstream=http://127.0.0.1:9102/
