kubernetes nginx入口控制器错误

Question

我使用的是google kubenretes引擎。我的集群节点版本是1.7。由于Google cloud不再支持该版本来创建新集群，因此我需要使用1.8或1.9。我在新的版本集群上实现我的nginx-ingress controller yaml文件时遇到了问题，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

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

     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

下面是我的nginx-ingress controller文件

在GKE (Google Kubernetes Engine)上运行时，您可能会在创建其中一些资源时遇到“权限被拒绝”错误。这与GKE处理RBAC和IAM权限的方式有细微差别，因此在运行上述命令之前，您应该将自己的权限“提升”为“cluster-admin”权限。如果您已经运行过上述命令，则应在提升权限后重新运行它们。

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
