Enabling user permissions to clone data volumes across namespaces

The isolating nature of namespaces means that users cannot by default clone resources between namespaces.

To enable a user to clone a virtual machine to another namespace, a user with the cluster-admin role must create a new cluster role. Bind this cluster role to a user to enable them to clone virtual machines to the destination namespace.

Creating RBAC resources for cloning data volumes

Create a new cluster role that enables permissions for all actions for the datavolumes resource.

Prerequisites

  • You must have cluster admin privileges.

Procedure

  1. Create a ClusterRole manifest:

    apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: <datavolume-cloner> (1)
rules:
- apiGroups: ["cdi.kubevirt.io"]
  resources: ["datavolumes/source"]
  verbs: ["*"]
    1 Unique name for the cluster role.

  2. Create the cluster role in the cluster:

    $ oc create -f <datavolume-cloner.yaml> (1)
    1 The file name of the ClusterRole manifest created in the previous step.

  3. Create a RoleBinding manifest that applies to both the source and destination namespaces and references the cluster role created in the previous step.

    apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: <allow-clone-to-user> (1)
  namespace: <Source namespace> (2)
subjects:
- kind: ServiceAccount
  name: default
  namespace: <Destination namespace> (3)
roleRef:
  kind: ClusterRole
  name: datavolume-cloner (4)
  apiGroup: rbac.authorization.k8s.io
    1 Unique name for the role binding.
    2 The namespace for the source data volume.
    3 The namespace to which the data volume is cloned.
    4 The name of the cluster role created in the previous step.

  4. Create the role binding in the cluster:

    $ oc create -f <datavolume-cloner.yaml> (1)
    1 The file name of the RoleBinding manifest created in the previous step.
