Usage

Task run using resolver:

apiVersion: tekton.dev/v1
kind: TaskRun
metadata:
    generateName: modify-data-object-taskrun-resolver-
spec:
    params:
    -   name: waitForSuccess
        value: 'true'
    -   name: manifest
        value: <DV or DS manifest>
    taskRef:
        params:
        -   name: catalog
            value: kubevirt-tekton-tasks
        -   name: type
            value: artifact
        -   name: kind
            value: task
        -   name: name
            value: modify-data-object
        -   name: version
            value: v0.22.0
        resolver: hub

As an example for manifest parameter, you can use this DV definition:

apiVersion: cdi.kubevirt.io/v1beta1
kind: DataVolume
metadata:
    generateName: example-dv-
spec:
    pvc:
        accessModes:
        - ReadWriteOnce
        resources:
            requests:
                storage: 100Mi
        volumeMode: Filesystem
    source:
        blank: {}

Usage in different namespaces

You can use task to do actions in different namespace. To do that, tasks requires special permissions. Apply these RBAC objects and permissions and update accordingly task run object with correct serviceAccount:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
    name: modify-data-object-task
rules:
-   apiGroups:
    - cdi.kubevirt.io
    resources:
    - datavolumes
    - datasources
    verbs:
    - get
    - create
    - delete
-   apiGroups:
    - ''
    resources:
    - pods
    verbs:
    - create
-   apiGroups:
    - ''
    resources:
    - persistentvolumeclaims
    verbs:
    - get
    - delete
