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

    EOF
    
    systemctl daemon-reload
    systemctl enable node_exporter
    systemctl restart node_exporter

kubectl exec -it prometheus-0 sh -c prometheus-server -n kube-system
    # 进入promethues的pod中
    /prometheus $ more /etc/config/prometheus.yml

kubectl create -f kube-state-metrics-rbac.yaml
    kubectl create -f kube-state-metrics-deployment.yaml
    kubectl create -f kube-state-metrics-service.yaml
    kubectl get pods -n kube-system

kubectl create -f alertmanager-configmap.yaml
    kubectl create -f alertmanager-pvc.yaml
    kubectl create -f alertmanager-deployment.yaml
    kubectl create -f alertmanager-service.yaml

kubectl create -f grafana.yaml
