设置每个命名空间的Helm RBAC

Question

Namespace="$1"

kubectl create namespace $Namespace
kubectl create serviceaccount "tiller-$Namespace" --namespace $Namespace
kubectl create role "tiller-role-$Namespace" /
    --namespace $Namespace /
    --verb=* /
    --resource=*.,*.apps,*.batch,*.extensions
kubectl create rolebinding "tiller-rolebinding-$Namespace" /
    --namespace $Namespace /
    --role="tiller-role-$Namespace" /
    --serviceaccount="$Namespace:tiller-$Namespace"
helm init /
    --service-account "tiller-$Namespace" /
    --tiller-namespace $Namespace
    --override "spec.template.spec.containers[0].command'='{/tiller,--storage=secret}"
    --upgrade
    --wait

官方文档中有bug吗？我看错了吗？

我不确定脚本中的--resource标志是否正确语法，这里是否允许星号符号“*”，看看GitHub上报道的这个问题。

$ kubectl create role "tiller-role-$Namespace" \
--namespace $Namespace \
--verb=* \
--resource=*.,*.apps,*.batch,*.extensions
the server doesn't have a resource type "*"

但您可以在集群中检查此角色对象：

Kubectl get role Tiller-role-$namespace-n$namespace-o yaml

kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: tiller-manager
  namespace: tiller-world
rules:
- apiGroups: ["", "batch", "extensions", "apps"]
  resources: ["*"]
  verbs: ["*"]

$ helm --tiller-namespace $Namespace version
Client: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"}
