kubernetes - 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 ，然后创建 ClusterRole kube-lego 失败。

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=[]

我尝试过 1.8.6-gke.0、1.8.7-gke.0 和 1.9.2-gke.0。

谢谢。

正如kube-lego issue 225中评论的那样:

Turns out the error I was receiving in an known issue with GKE 1.6. I resolved by following this article:

get current google identity

$ gcloud info | grep Account
Account: [myname@example.org]

grant cluster-admin to your current identity

$ 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 issue 99

指的是Adds official RBAC rules ，它应用正确的设置:

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