无法使用 RBAC 列出部署资源

Question

我在 Kubernetes 中为用户使用 x509 身份验证，效果很好。然而，虽然提供对部署的访问似乎并没有正常工作，如下所示：

角色：

# kubectl get rolebindings devops-rb -n demo -o yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  creationTimestamp: 2018-03-26T13:43:49Z
  name: devops-rb
  namespace: demo
  resourceVersion: "2530329"
  selfLink: /apis/rbac.authorization.k8s.io/v1/namespaces/demo/rolebindings/devops-rb
  uid: b6c17e28-30fb-11e8-b530-000d3a11bb2f
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: Role
  name: devops-role
subjects:
- apiGroup: rbac.authorization.k8s.io
  kind: Group
  name: devops

角色绑定：

# kubectl get roles devops-role -n demo -o yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  creationTimestamp: 2018-03-26T13:43:49Z
  name: devops-role
  namespace: demo
  resourceVersion: "2538402"
  selfLink: /apis/rbac.authorization.k8s.io/v1/namespaces/demo/roles/devops-role
  uid: b6bee0fb-30fb-11e8-b530-000d3a11bb2f
rules:
- apiGroups:
  - ""
  resources:
  - pods
  - secrets
  - services
  - replicasets
  - persistentvolumeclaims
  - deployments
  verbs:
  - get
  - list
  - watch

正在尝试使用用户配置列出部署：

# kubectl --kubeconfig /root/.kube/config-tesla get deploy -n demo
Error from server (Forbidden): deployments.extensions is forbidden: User "tesla" cannot list deployments.extensions in the namespace "demo"

正在尝试使用管理员配置列出部署：

# kubectl  get deploy -n demo
NAME              DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
wordpress         1         1         1            1           13d
wordpress-mysql   1         1         1            1           13d

正在尝试列出 pods 使用用户配置：

# kubectl --kubeconfig /root/.kube/config-tesla get po -n demo
NAME                               READY     STATUS    RESTARTS   AGE
ncp-centos-pod                     1/1       Running   0          12d
wordpress-77d578745-vdgr9          1/1       Running   0          13d
wordpress-mysql-58cf8dc9f9-pzvbs   1/1       Running   0          13d

正在尝试使用管理员配置列出 pods：

# kubectl  get pods -n demo
NAME                               READY     STATUS    RESTARTS   AGE
ncp-centos-pod                     1/1       Running   0          12d
wordpress-77d578745-vdgr9          1/1       Running   0          13d
wordpress-mysql-58cf8dc9f9-pzvbs   1/1       Running   0          13d

Answer 1

副本集和部署存在于 "extensions" 和 "apps" API 组中，而不存在于旧版“”组中

尝试：

rules:
- apiGroups:
  - ""
  resources:
  - pods
  - secrets
  - services
  - persistentvolumeclaims
  verbs:
  - get
  - list
  - watch
- apiGroups:
  - extensions
  - apps
  resources:
  - deployments
  - replicasets
  verbs:
  - get
  - list
  - watch

Answer 2

如果我没理解错的话..

检查：

kubectl describe clusterrole |grep devops-role
kubectl describe clusterrole |grep devops-rb
kubectl describe clusterrole | less

无法使用 RBAC 列出部署资源

Unable to list deployments resources using RBAC
