master节点导入prometheus软件包
[root@k8s-master ~]# mkdir prometheus
[root@k8s-master ~]# cd prometheus/
[root@k8s-master prometheus]# ls
kube-prometheus-0.13.0.zip解压
[root@k8s-master prometheus]# unzip kube-prometheus-0.13.0.zip

node节点
node节点导入镜像
[root@k8s-node1 ~]# mkdir prometheus
[root@k8s-node1 ~]# cd prometheus/
[root@k8s-node1 prometheus]# rz
rz waiting to receive.**[root@k8s-node1 prometheus]# ls
prometheus.zip解压
[root@k8s-node1 prometheus]# unzip prometheus.zip
Archive: prometheus.zip
inflating: prometheus.tar 从tar包中加载镜像
[root@k8s-node1 prometheus]# ls

[root@k8s-node1 prometheus]# docker load -i prometheus.tar 
部署 prometheus
修改映射端口
[root@k8s-master manifests]# vim prometheus-service.yaml
[root@k8s-master manifests]# vim grafana-service.yaml
[root@k8s-master manifests]# vim alertmanager-service.yaml 以上配置文件分别增加如下配置：
spec:
type: NodePort
提交
kubectl create -f ./setup
kubectl create -f ./查看pod
pod和svc正常启动

prometheus就是通过内部端口9090进行访问的
如何设置告警信息呢？
如下操作：
进到prometheus-k8s-0 容器里
[root@k8s-master manifests]# kubectl -n monitoring get po

[root@k8s-master manifests]# kubectl -n monitoring exec -it prometheus-k8s-0 -- sh
/prometheus $
/prometheus $ cd 
主要文件：prometheus.yml
告警规则：rules
打开 # - alertmanager:9093
