kuboard如何部署redis？

在K8S上部署redis

如 在K8S上部署mysql 所述，auth-server、user-center、api-gateway 都需要使用 redis 服务，本文描述如何使用 Kuboard 在 Kubernetes 上部署 redis。

本文将使用 redis官方镜像 进行部署。

部署redis

在 Kuboard 界面进入名称空间 （自己的命令空间），点击 创建工作负载 按钮，并填写表单，如下图所示：

基本信息

容器信息

• 容器启动检查探针

• 容器存活检查探针

存储挂载

• 配置字典

dir /data #数目录
port 6379 #指定端口
bind 0.0.0.0 #允许外部访问
appendonly yes  #开启持久化
protected-mode no
requirepass 123qwe## #密码

高级设置

服务/应用路由

最后点击保存。

命令行配置文件如下
