kubectl apply -f taosd-statefulset.yaml -n dev-rd2

4.（1-3）是前期主备，当然k8s环境事先要准备好，当前使用的是Harbor用来管理镜像

5.主要的操作流程

>安装Harbor

>安装K8s

>安装Docker Desktop

>docker pull tdengine/tdengine:3.3.6.9 下载镜像

>docker save -o tdengine-3.3.6.9.tar tdengine/tdengine:3.3.6.9 

>docker push registry.abcd.com/rd-lib/tdengine/tdengine:3.3.6.9

>部署 kubectl apply -f taosd-service.yaml -n dev-rd2和kubectl apply -f taosd-statefulset.yaml -n dev-rd2

>K8sweb配置服务外部访问IP

>K8s修改配置

>K8s重建副本

>测试tdengine是否正常
