GKE 上的 Istio 安装失败，"clusterroles.rbac.authorization.k8s.io "istio-pilot" is forbidden: attempt to grant extra privileges"

Question

正在尝试在 GKE（Google 容器引擎）上安装 istio 0.1.6。

运行按照以下步骤检查集群是否启用了 RBAC（基于角色的访问控制）：

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

它显示'beta'版本，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:...

集群角色绑定创建没有帮助：

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

知道如何解决这个问题吗？

CLOUDSDK_CONTAINER_USE_CLIENT_CERTIFICATE=True gcloud container clusters get-credentials...

将 CLOUDSDK_CONTAINER_USE_CLIENT_CERTIFICATE=True 添加到 gcloud container clusters get-credentials 命令，该命令使用适当的凭据更新 kubeconfig 文件以将 kubectl 指向容器引擎集群，解决了问题:)

Answer 2

我运行喜欢这个。对我来说，解决方案是 --user 的电子邮件地址参数必须小写。这意味着 --user=foo.bar@example.com 而不是 --user=Foo.Bar@example.com
