azure - 在aks中部署nginx-ingress，没有rbac问题

Question

我是 Kubernetes 新手，正在尝试使用 Helm 在 Aks 集群中部署 nginx-ingress。

使用 az-cli 创建集群后，尝试使用以下命令部署 nginx-ingress:

helm install stable/nginx-ingress -n nginx-ingress --namespace kube-system --set rbac.create=false

但是我在命令行中遇到以下错误:

Error: release nginx-ingress failed: clusterroles.rbac.authorization.k8s.io "nginx-ingress" is forbidden: attempt to grant extra privileges: [PolicyRule{Resources:["configmaps"], APIGroups:[""], Verbs:["list"]} PolicyRule{Resources:["configmaps"], APIGroups:[""], Verbs:["watch"]} PolicyRule{Resources:["endpoints"], APIGroups:[""], Verbs:["list"]} PolicyRule{Resources:["endpoints"], APIGroups:[""], Verbs:["watch"]} PolicyRule{Resources:["nodes"], APIGroups:[""], Verbs:["list"]} PolicyRule{Resources:["nodes"], APIGroups:[""], Verbs:["watch"]} PolicyRule{Resources:["pods"], APIGroups:[""], Verbs:["list"]} PolicyRule{Resources:["pods"], APIGroups:[""], Verbs:["watch"]} PolicyRule{Resources:["secrets"], APIGroups:[""], Verbs:["list"]} PolicyRule{Resources:["secrets"], APIGroups:[""], Verbs:["watch"]} PolicyRule{Resources:["nodes"], APIGroups:[""], Verbs:["get"]} PolicyRule{Resources:["services"], APIGroups:[""], Verbs:["get"]} PolicyRule{Resources:["services"], APIGroups:[""], Verbs:["list"]} PolicyRule{Resources:["services"], APIGroups:[""], Verbs:["update"]} PolicyRule{Resources:["services"], APIGroups:[""], Verbs:["watch"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["get"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["list"]} PolicyRule{Resources:["ingresses"], APIGroups:["extensions"], Verbs:["watch"]} PolicyRule{Resources:["events"], APIGroups:[""], Verbs:["create"]} PolicyRule{Resources:["events"], APIGroups:[""], Verbs:["patch"]} PolicyRule{Resources:["ingresses/status"], APIGroups:["extensions"], Verbs:["update"]}] user=&{system:serviceaccount:kube-system:default 5ddc4e18-5607-11e8-b434-0a58ac1f0fc5 [system:serviceaccounts system:serviceaccounts:kube-system system:authenticated] map[]} ownerrules=[] ruleResolutionErrors=[]

我使用的是最新的 az cli、Helm 和 Ubuntu 16.04 (Xenial Xerus)。

我刚刚克服了这个问题。在我看来，现在可以在 AKS 上启用 RBAC，但只是部分启用？我刚刚于 2018 年 5 月 11 日创建了集群。
