kubernetes - 受限制的 Kubernetes 仪表板？

Question

是否可以有一个受限的 Kubernetes 仪表板？这个想法是让一个 pod 在集群中运行 kubectl proxy(受基本 HTTP 身份验证保护)以快速了解状态:

• pod 的日志输出
• 运行服务和 pod
• 当前 CPU/内存使用情况

但是，我不希望用户能够执行“特权”操作，例如创建新 pod、删除 pod 或访问 secret 。

是否有一些选项可以使用指定用户或受限权限启动仪表板？

根据 lwolf 的回答，我使用了 the kubernetes-dashboard.yaml并将其更改为在默认命名空间中的从站上运行。

重要的变化是 kind: ClusterRole, name: view 部分，它将 view 角色分配给仪表板用户。
