無法在Google Cloud Platform中啟動Kubernetes Federation

Question

我正在嘗試設置kubernetes聯盟。 當我運行以下命令時，我得到一個錯誤：

# Set the project and domain name
export PROJECT=abc-9102-1sf
export DNS_ZONE=echo.examplefed.com.

# Create the clusters
gcloud container clusters create west-cluster --zone us-west1-c --scopes "cloud-platform,storage-ro,logging-write,monitoring-write,service-control,service-management,https://www.googleapis.com/auth/ndev.clouddns.readwrite" --preemptible &
gcloud container clusters create east-cluster --zone us-east1-b --scopes "cloud-platform,storage-ro,logging-write,monitoring-write,service-control,service-management,https://www.googleapis.com/auth/ndev.clouddns.readwrite" --preemptible &

# Workaround for RBAC error
# https://github.com/kubernetes/kubernetes/issues/42559
gcloud config set container/use_client_certificate True
export CLOUDSDK_CONTAINER_USE_CLIENT_CERTIFICATE=True

# Get credentials
gcloud container clusters get-credentials west-cluster --zone=us-west1-c
gcloud container clusters get-credentials east-cluster --zone=us-east1-b

# Aliases
kubectl config set-context east --cluster=gke_${PROJECT}_us-east1-b_east-cluster --user=gke_${PROJECT}_us-east1-b_east-cluster
kubectl config set-context west --cluster=gke_${PROJECT}_us-west1-c_west-cluster --user=gke_${PROJECT}_us-west1-c_west-cluster

# Initiate Federation. After this step I get the error.
kubefed init kfed  --host-cluster-context=east  --dns-zone-name=${DNS_ZONE}  --dns-provider=google-clouddns

正在為聯邦系統組件創建名稱空間聯合系統...服務器錯誤（禁止）：名稱空間被禁止：用戶“客戶端”無法在集群范圍內創建名稱空間：未知用戶“客戶端”。

kubefed和kubectl的版本是1.8.8：

gcp@user:~$ kubectl version
Client Version: version.Info{Major:"1", Minor:"8", GitVersion:"v1.8.8", GitCommit:"2f73858c9e6ede659d6828fe5a1862a48034a0fd", GitTreeState:"clean", BuildDate:"2018-02-09T21:30:57Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}

在花了幾個小時之后，我設法使用以下命令對其進行了修復。 請注意，必須針對您擁有的每個上下文執行該操作：

kubectl create clusterrolebinding cluster-admin-binding \
--clusterrole cluster-admin --user $(gcloud config get-value account) --context east

kubectl create clusterrolebinding cluster-admin-binding \
--clusterrole cluster-admin --user $(gcloud config get-value account) --context west

並且不要運行此：

# Workaround for RBAC error
# https://github.com/kubernetes/kubernetes/issues/42559
gcloud config set container/use_client_certificate True
export CLOUDSDK_CONTAINER_USE_CLIENT_CERTIFICATE=True
