前提：

k8s中部署容器日志采集系统。

各组件介绍请查看以前文件：https://www.jianshu.com/writer#/notebooks/29770203/notes/41804428/preview

这次我们使用的环境如下：
k8s v1.15.3
helm 2.14.3
efk： v6.8.4
动态存储： Storageckass

下载好官方的elastic，选择版本，
elastic的helm仓库的github：https://github.com/elastic/helm-charts

一部署ES

更改配置项：增加storageclass，对ES的数据持久化

cd helm-charts/elasticsearch
vim value.yaml  #更改配置
helm install  . --name=elasticsearch  --namespace=kube-public #部署ES
