ServiceAccount不能在名称空间中列出资源“ pods”，尽管它具有适当的资源角色

Question

我在自定义名称空间中具有以下定义：

apiVersion: v1
kind: ServiceAccount
metadata:
  name: test-sa
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: test
rules:
  - apiGroups: [""]
    resources: ["pods", "pods/exec"]
    verbs: ["get", "list", "delete", "patch", "create"]
  - apiGroups: ["extensions", "apps"]
    resources: ["deployments", "deployments/scale"]
    verbs: ["get", "list", "delete", "patch", "create"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: test
subjects:
  - kind: User
    name: test-sa
    apiGroup: rbac.authorization.k8s.io
roleRef:
  kind: Role
  name: test
  apiGroup: rbac.authorization.k8s.io

正在运行describe role test

Name:         test

  pods/exec                     []                 []              [get list delete patch create]
  pods                          []                 []              [get list delete patch create]
  deployments.apps/scale        []                 []              [get list delete patch create]
  deployments.apps              []                 []              [get list delete patch create]
  deployments.extensions/scale  []                 []              [get list delete patch create]
  deployments.extensions        []                 []              [get list delete patch create]

[当我尝试在使用此服务帐户的Pod中运行命令kubectl get pods时，出现以下错误：

来自服务器的错误（禁止）：禁止播客：用户“ system：serviceaccount：test-namespace：test-sa”无法列出资源API组“”中命名空间“ test-namespace”中的“ pods”

哪里配置错误？

问题出在subjects的RoleBinding。正确的定义是：

apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: test
subjects:
  - kind: ServiceAccount
    name: test-sa
roleRef:
  kind: Role
  name: test
  apiGroup: rbac.authorization.k8s.io
