[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 ./

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
