Authentication

Choose one of the authentication method sections to follow.

OAuth

• Create sample identity file

  htpasswd -c -B -b ./non_admin_user.htpasswd <non-admin-user> <password>

• Create secret from the previously created identity file in your cluster

  oc create secret generic non-admin-user --from-file=htpasswd=./non_admin_user.htpasswd -n openshift-config

• Add new entry to spec.identityProviders field from OAuth cluster (oc get OAuth cluster)

  ...
  spec:
    identityProviders:
    - name: # non-admin-user
      mappingMethod: claim
      type: HTPasswd
      htpasswd:
        fileData:
          name: # non-admin-user

• Apply permissions to your non admin user

Permissions

• Create non admin user namespace

  oc create namespace <non-admin-user-namespace>

• Ensure non admin user have appropriate permissions in its namespace, i.e., non admin user have editor roles for the following objects

  • nonadminbackups.oadp.openshift.io
  • nonadminrestores.nac.oadp.openshift.io

  For example

    # config/rbac/nonadminbackup_editor_role.yaml
    - apiGroups:
        - oadp.openshift.io
      resources:
        - nonadminbackups
      verbs:
        - create
        - delete
        - get
        - list
        - patch
        - update
        - watch
    - apiGroups:
        - oadp.openshift.io
      resources:
        - nonadminbackups/status
      verbs:
        - get
    # config/rbac/nonadminrestore_editor_role.yaml
    - apiGroups:
      - oadp.openshift.io
      resources:
      - nonadminrestores
      verbs:
      - create
      - delete
      - get
      - list
      - patch
      - update
      - watch
    - apiGroups:
      - oadp.openshift.io
      resources:
      - nonadminrestores/status
      verbs:
      - get

  For example, make non admin user have admin ClusterRole permissions on its namespace

  oc create rolebinding <non-admin-user>-namespace-admin --clusterrole=admin --user=<non-admin-user> --namespace=<non-admin-user-namespace>
