kubernetes（k8s）安装 Prometheus + Grafana

组件说明

====

MetricServer：是kubernetes集群资源使用情况的聚合器，收集数据给kubernetes集群内使用，如 kubectl,hpa,scheduler等。

PrometheusOperator：是一个系统监测和警报工具箱，用来存储监控数据。

NodeExporter：用于各node的关键度量指标状态数据。

KubeStateMetrics：收集kubernetes集群内资源对象数据，制定告警规则。

Prometheus：采用pull方式收集apiserver，scheduler，controller-manager，kubelet组件数据，通过http协议传输。

Grafana：是可视化数据统计和监控平台。

进入目录修改镜像地址

==========

若访问Google畅通无阻即可无需修改，跳过即可
