在k8s中部署Prometheus--更新中

下载kubernetes中的Prometheus文件相关源码

https://github.com/kubernetes/kubernetes.git
cp -rf kubernetes/cluster/addons/prometheus/ /root/
cd prometheus/

（1）先部署promethethus配置文件

kubectl create -f prometheus-rbac.yaml
kubectl create -f prometheus-rules.yaml
kubectl create -f prometheus-configmap.yaml
kubectl get storageclass # 确定有配置storageclass 
vi prometheus-statefulset.yaml
kubectl create -f prometheus-statefulset.yaml
kubectl create -f prometheus-service.yaml

（需添加的内容：配置动态存储方式）

此处使用pvc动态存储方式，修改 prometheus-statefulset.yaml为

storageClassName: managed-nfs-storage

kubectl get svc -n kube-system

wget https://github.com/prometheus/node_exporter/releases/download/v0.17.0/node_exporter-0.17.0.linux-amd64.tar.gz

tar zxf node_exporter-0.17.0.linux-amd64.tar.gz
mv node_exporter-0.17.0.linux-amd64 /usr/local/node_exporter

kubectl exec -it prometheus-0 sh -c prometheus-server -n kube-system
