Prometheus（普罗米修斯）是一套开源的监控系统.由SoundCloud公司开发。Docker、Mesos、Kubernetes环境常用Prometheus来监控，下图为Prometheus的架构图
k8s部署好后，就可以进行Prometheus部署，这里采用k8s进行部署
以下均在master节点执行
一 安装好git后，执行git clone
git clone https://github.com/coreos/kube-prometheus.git
二 由于各种原因，我们从阿里云上下载镜像，并重新tag,以下master,worker节点均执行

三，在master 上创建pod
kubectl create -f manifests/setup
kubectl create -f manifests/
kubectl get all -n monitoring
四，配置外部访问
kubectl edit -n monitoring service prometheus-k8s
kubectl edit -n monitoring service grafana
kubectl edit -n monitoring service alertmanager-main
三个配置文件中要修改下面的端口和类型
nodePort: 10021
type: NodePort
kubectl get svc -n monitoring进行验证
四 访问web
访问 Prometheus http://master:10021
访问 Grafana http://master:10022 需要数据源绑定
访问 Alert Manager http://master:10022
kuPrometheus 卸载
bectl delete --ignore-not-found=true -f manifests/ -f manifests/setup
