+pod意外重启后，k8s不能保证pod的ip不发生变化，但是能保证域名不变，基于这一特性，doris开启fqdn时，能保证pod意外重启后，还能正常提供服务。
+
+k8s部署doris的方法请参考[K8s部署doris](../../../community/developer-guide/k8s-deploy.md)
+
+### 服务器切换网卡
+
+例如有一个be节点的服务器有两个网卡，对应的ip分别为192.192.192.2和10.10.10.3,目前用192.192.192.2对应的网卡，可以按照下述步骤操作：
+
+1. 在fe所在机器的etc/hosts文件增加一行 192.192.192.2 be1_fqdn

1. 在fe所在机器的`etc/hosts`文件增加一行 `192.192.192.2 be1_fqdn`

+# K8s部署doris
+
+</version>
+
+## 环境准备
+
+- 安装 k8s
+- 构建或下载doris镜像
+ - 构建镜像 [Doris Docker 快速搭建开发环境](./docker-dev)
+ - 下载镜像 https://hub.docker.com/r/apache/doris/tags
+- 创建或下载doris on k8s的yml文件
+ -
https://github.com/apache/doris/blob/master/docker/runtime/k8s/doris_follower.yml
+ -
https://github.com/apache/doris/blob/master/docker/runtime/k8s/doris_be.yml
+ -
https://github.com/apache/doris/blob/master/docker/runtime/k8s/doris_cn.yml
+
+## 启动集群
+启动follower： kubectl create -f doris_follower.yml
+
+启动backend： kubectl create -f doris_be.yml
+
+启动backend_cn： kubectl create -f doris_cn.yml
+
+## 扩缩容
+
+- fe_follower
+ - 目前不支持扩缩容，建议按需初始化1个或者3个节点
+- backend
+ - 命令：kubectl scale statefulset doris-be-cluster1 --replicas=4
+- backend_cn
+ - 命令：kubectl scale statefulset doris-cn-cluster1 --replicas=4
+
+## 验证
+
+使用 mysql-client 连接到 FE，执行 show backends，show frontends等操作查看各节点状态
