Can t list the deployment resources using RBAC

0 votes

I've given the x509 authentication for a user in kubernetes, but deployments access doesn't seem to be working fine.

Roles:

# 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

Role Bindings:

# 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

Trying to list deployments using user config:

# 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"

Trying to list deployments using the admin config:

# 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

Trying to list pods using user config:

# kubectl --kubeconfig /root/.kube/config-tesla get po -n demo
NAME                               READY     STATUS    RESTARTS   AGE

wordpress-mysql-58cf8dc9f9-pzvbs   1/1       Running   0          13d

Trying to list pods using admin config:

# kubectl  get pods -n demo

"extensions" and "apps" API groups cover replicasets and deployments.

try this:

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