k8s上部署redis哨兵记录

- k8s界面使用kuboard
- 部署使用1主1备1哨兵
- 使用思路为master节点部署后，slave节点使用master的serviceip与master节点进行互通，哨兵进程与master、slave使用service ip互通
- 参考链接  [bitnami/redis-sentinel - Docker Image | Docker Hub](https://hub.docker.com/r/bitnami/redis-sentinel)
- 连接中是有docker-compose启动的配置文件，未指明在k8s上如何使用，因此写了本操作指导【yaml文件内容在kuboard界面生成】
