kubernetes - 即使我是所有者和管理员，也无法在 GKE 中创建集群角色

Question

创建新的 GKE 集群后，创建集群角色失败并显示以下错误:

Error from server (Forbidden): error when creating "./role.yaml":
clusterroles.rbac.authorization.k8s.io "secret-reader" is forbidden: 
attempt to grant extra privileges: [PolicyRule{Resources:["secrets"], 
APIGroups:[""], Verbs:["get"]} PolicyRule{Resources:["secrets"], 
APIGroups:[""], Verbs:["watch"]} PolicyRule{Resources:["secrets"], 
APIGroups:[""], Verbs:["list"]}] user=&{XXX@gmail.com  
[system:authenticated] map[authenticator:[GKE]]} ownerrules= . 
[PolicyRule{Resources:["selfsubjectaccessreviews" 
"selfsubjectrulesreviews"], APIGroups:["authorization.k8s.io"], Verbs: 
["create"]} PolicyRule{NonResourceURLs:["/api" "/api/*" "/apis" 
"/apis/*" "/healthz" "/swagger-2.0.0.pb-v1" "/swagger.json" 
"/swaggerapi" "/swaggerapi/*" "/version"], Verbs:["get"]}] 
ruleResolutionErrors=[]

我的账户在 IAM 中具有以下权限:

Kubernetes Engine Admin

Kubernetes Engine Cluster Admin

Owner

这是我的 role.yaml (来自 Kubernetes docs) :

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: secret-reader
rules:
- apiGroups: [""]
  resources: ["secrets"]
  verbs: ["get", "watch", "list"]

根据RBAC docs of GCloud ，我需要

create a RoleBinding that gives your Google identity a cluster-admin role before attempting to create additional Role or ClusterRole permissions.

所以我尝试了 this :

export GCP_USER=$(gcloud config get-value account | head -n 1)
kubectl create clusterrolebinding cluster-admin-binding
--clusterrole=cluster-admin --user=$GCP_USER

成功了，但在创建集群角色时我仍然遇到相同的错误。
任何想法我可能做错了什么？

Answer 1

根据 Google Container Engine docs您必须首先创建一个 RoleBinding，它授予您要创建的角色中包含的所有权限。

获取当前的谷歌身份

$ gcloud info | grep Account

Account: [myname@example.org]

将 cluster-admin 授予您当前的身份

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

Clusterrolebinding "myname-cluster-admin-binding" created

现在您可以毫无问题地创建您的 ClusterRole。
