Ratel是一个Kubernetes多集群资源管理平台，基于管理Kubernetes的资源开发，
可以管理Kubernetes的Deployment、DaemonSet、StatefulSet、Service、Ingress、Pods、Nodes、CronJob等。
也可以管理Kubernetes的Role、ClusterRole、Rolebinding、ClusterRoleBinding、Secret、ConfigMap、PV、PVC等。
立志于基于图形界面管理所有的Kubernetes的资源。
同时具备了一些常用的功能，比如跨集群资源复制、一键项目迁移、图形化资源编辑、资源一键回滚及更新、一键式用户权限管理等，
并且具备K8s不具备的功能，比如ConfigMap和Secret备份功能。
