在GKE上安装Istio失败,出现“clusterroles.rbac.authorization.k8s.io”禁止“Istio pilot”:尝试授予额外权限

正在尝试安装 istio 0.1.6 在GKE(谷歌容器引擎)上。

$ kubectl api-versions | grep rbac
rbac.authorization.k8s.io/v1beta1

它显示测试版,所以我运行:

$ kubectl apply -f istio-0.1.6/install/kubernetes/istio-rbac-beta.yaml
Error from server (Forbidden): error when creating "istio-0.1.6/install/kubernetes/istio-rbac-beta.yaml": clusterroles.rbac.authorization.k8s.io "istio-pilot" is forbidden: attempt to grant extra privileges:...

群集角色绑定创建没有帮助:

$ kubectl create clusterrolebinding myname-cluster-admin-binding --clusterrole=cluster-admin --user=myname@example.org

知道怎么解决吗?

$ kubectl version
