k8s_v1beta1_cluster_role_binding: role_ref_name is overwritten by object name

[echupriyanov]

Hi, I'm trying to create ClusterRoleBinding, using ansible-kubernetes-modules via following ansible specification:

- name: Grant permissions to GitLab Runner SA
    k8s_v1beta1_cluster_role_binding:
      state: present
      name: gitlab-runner2
      role_ref_api_group: rbac.authorization.k8s.io
      role_ref_kind: ClusterRole
      role_ref_name: cluster-admin
      subjects:
        - kind: ServiceAccount
          name: gitlab-runner
          namespace: "{{gitlab_ns}}"

As a result, I expect ServiceAccount gitlab-runner to be bound to ClusterRole cluster-admin
But, instead, I'm getting:

apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  creationTimestamp: 2017-11-05T12:02:14Z
  name: gitlab-runner2
  resourceVersion: "2589558"
  selfLink: /apis/rbac.authorization.k8s.io/v1beta1/clusterrolebindings/gitlab-runner2
  uid: 29a5405b-c221-11e7-acf9-0ea794e93120
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: gitlab-runner2
subjects:
- kind: ServiceAccount
  name: gitlab-runner
  namespace: default

I suspect this happens, because role_ref_name has alias name, and there is overwritten by top-level name field

Also, is I use resource_definition to specify ClusterRoleBinding like this:

  - name: Grant permissions to GitLab Runner SA
    k8s_v1beta1_cluster_role_binding:
      state: present
      name: gitlab-runner2
      resource_definition:
        apiVersion: rbac.authorization.k8s.io/v1beta1
        kind: ClusterRoleBinding
        metadata:
          name: gitlab-runner2
        roleRef:
          apiGroup: rbac.authorization.k8s.io
          kind: ClusterRole
          name: cluster-admin
        subjects:
        - kind: ServiceAccount
          name: gitlab-runner
          namespace: default

I'm getting the following error:
