Question

我正在使用google kubenretes引擎。我的群集节点版本是1.7。由于Google云无法支持该版本创建新群集，因此我需要使用1.8或1.9。我在新版本的集群中遇到了我的nginx-ingress-controller yaml文件的问题，但我一直收到这个错误：

     Using build: https://github.com/bprashanth/contrib.git - git-92b2bac when using gcr.io/google_containers/nginx-ingress-controller:0.8.3

使用quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.9.0时出现此错误

     It seems the cluster it is running with Authorization enabled (like RBAC) and there is no permissions for the ingress controller. Please check the configuration

这是我的nginx-ingress-controller文件

在GKE（Google Kubernetes Engine）上运行时，在创建其中一些资源时可能会遇到“权限被拒绝”错误。这是GKE处理RBAC和IAM权限的方式的细微差别，因此，在运行上述命令之前，应将自己的特权“提升”为“集群管理员”的特权。如果您已经运行了上述命令，则应在提升权限后再次运行它们。

kubectl create clusterrolebinding cluster-admin-binding \
    --clusterrole=cluster-admin \
    --user=$(gcloud config get-value core/account)

尝试点击此命令，然后应用文件
