部署 Redis（7.2.3）
部署说明：通过 nodeSelector 固定到 worker3 节点上。并使用 worker3 上的原生文件系统目录 /.data
部署文件说明
- 通过 config 定制
redis.conf的配置， 比如 密码 - 有使用 LoadBalancer 类型的 Service， 通过
externalIPs指定外部 IP - 通过 hostPath 挂载宿主机的目录， 用于持久化数据提升IO性能
- 部署于
middleware命名空间 - 镜像使用
registry.cn-hongkong.aliyuncs.com/jansora/redis:7.2.3， 拷贝自官方镜像，无改动
