kubespray 仪表板警告禁止弹出窗口

Question

我正在尝试使用 kubespray 在一台机器上设置一个新的 kubernetes 集群（提交 7e84de2ae116f624b570eadc28022e924bd273bc）。

运行剧本后（在新的 ubuntu 16.04 上），我打开仪表板并看到那些警告弹出窗口：

- configmaps is forbidden: User "system:serviceaccount:default:default" cannot list configmaps in the namespace "default"
- persistentvolumeclaims is forbidden: User "system:serviceaccount:default:default" cannot list persistentvolumeclaims in the namespace "default"
- secrets is forbidden: User "system:serviceaccount:default:default" cannot list secrets in the namespace "default"
- services is forbidden: User "system:serviceaccount:default:default" cannot list services in the namespace "default"

- daemonsets.apps is forbidden: User "system:serviceaccount:default:default" cannot list daemonsets.apps in the namespace "default"
- pods is forbidden: User "system:serviceaccount:default:default" cannot list pods in the namespace "default"

- statefulsets.apps is forbidden: User "system:serviceaccount:default:default" cannot list statefulsets.apps in the namespace "default"

kubectl 命令看起来不错（代理有效，列出 Pod 等。没有返回错误，/api可以访问），但是仪表板似乎无法获取任何有用的信息。我应该如何调试呢？

Answer 1

kubectl create clusterrolebinding default-admin --clusterrole cluster-admin --serviceaccount=default:default

似乎可以解决问题 - 不过我欢迎一个解释。（这是kubespray的疏忽吗？我需要在那里设置一个变量？它与RBAC有关吗？）
