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"
- ingresses.extensions is forbidden: User "system:serviceaccount:default:default" cannot list ingresses.extensions 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"
- events is forbidden: User "system:serviceaccount:default:default" cannot list events in the namespace "default"
- deployments.apps is forbidden: User "system:serviceaccount:default:default" cannot list deployments.apps in the namespace "default"
- replicasets.apps is forbidden: User "system:serviceaccount:default:default" cannot list replicasets.apps in the namespace "default"
- jobs.batch is forbidden: User "system:serviceaccount:default:default" cannot list jobs.batch in the namespace "default"
- cronjobs.batch is forbidden: User "system:serviceaccount:default:default" cannot list cronjobs.batch in the namespace "default"
- replicationcontrollers is forbidden: User "system:serviceaccount:default:default" cannot list replicationcontrollers 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(代理工作,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。我应该如何去调试呢?

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

似乎可以解决问题-不过,我欢迎您做出解释。(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?)

仪表板 pod 使用默认服务帐户运行,并且该帐户默认没有权限,您可以在仪表板 pod 中看到默认服务帐户的令牌:

kubectl exec -it <dashboard-pod> bash
ls -al /var/run/secrets/kubernetes.io/serviceaccount

您在 answer 中运行的命令为仪表板 pod 使用的默认服务帐户设置所需的权限。
