无法为kube-lego创建ClusterRole

Question

我做了这个例子https://github.com/jetstack/kube-lego/tree/master/examples/gce,然后无法创建ClusterRole kube-lego.

错误是:

Error from server (Forbidden): error when creating "k8s/kube-lego/hoge.yaml": clusterroles.rbac.authorization.k8s.io "kube-lego" is forbidden: attempt to grant extra privileges: [PolicyRule{Resources:["pods"], APIGroups:[""], Verbs:["get"]} PolicyRule{Resources:["pods"], APIGroups:[""], Verbs:["list"]} PolicyRule{Resources:["services"], APIGroups:[""], Verbs:["create"]} PolicyRule{Resources:["services"], APIGroups:[""], Verbs:["get"]} PolicyRule{Resources:["services"], APIGroups:[""], Verbs:["delete"]} PolicyRule{Resources:["services"], APIGroups:[""], Verbs:["update"]} PolicyRule{Resources:["endpoints"], APIGroups:[""], Verbs:["create"]} PolicyRule{Resources:["endpoints"], APIGroups:[""], Verbs:["get"]} PolicyRule{Resources:["endpoints"], APIGroups:[""], Verbs:["delete"]} PolicyRule{Resources:["endpoints"], APIGroups:[""], Verbs:["update"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["get"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["update"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["create"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["list"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["patch"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["delete"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["watch"]} PolicyRule{Resources:["endpoints"], APIGroups:[""], Verbs:["get"]} PolicyRule{Resources:["endpoints"], APIGroups:[""], Verbs:["create"]} PolicyRule{Resources:["endpoints"], APIGroups:[""], Verbs:["update"]} PolicyRule{Resources:["secrets"], APIGroups:[""], Verbs:["get"]} PolicyRule{Resources:["secrets"], APIGroups:[""], Verbs:["create"]} PolicyRule{Resources:["secrets"], APIGroups:[""], Verbs:["update"]}] user=&{myemail@gmail.com  [system:authenticated] map[]} 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=[]

我试过1.8.6-gke.0,1.8.7-gke.0和1.9.2-gke.0.

谢谢.

如kube-lego问题225所述:

原来我在GKE 1.6的已知问题中收到的错误.我通过以下文章解决了这个问题

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

有关要定义的实际RBAC,请参阅问题99

它指的是添加官方RBAC规则,它应用了正确的设置:

# RBAC objects
kubectl apply -f lego/service-account.yaml
kubectl apply -f lego/cluster-role.yaml
kubectl apply -f lego/cluster-role-binding.yaml
