我试图在一台使用kubespray的计算机上建立一个新的kubernetes集群(提交7e84de2ae116f624b570eadc28022e924bd273bc)。
在运行剧本之后(在新的ubuntu 16.04上),我打开仪表板并看到那些警告弹出窗口:

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

kubectl命令看起来不错(代理工作,列出pod等。不返回错误,/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?
答案 0 :(得分:1)
仪表板容器正在使用默认服务帐户运行,并且该帐户默认情况下没有权限,您可以在仪表板容器内部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
您在答案中运行的命令为仪表板窗格使用的默认服务帐户设置所需的权限。
答案 1 :(得分:0)
kubectl create clusterrolebinding default-admin --clusterrole cluster-admin --serviceaccount=default:default
似乎可以解决问题-不过,我欢迎您提供解释。 (这是对kubespray的监督吗?我需要在其中设置一个变量吗?与RBAC有关吗?)
