Chapter 5. Managing non-versioned and versioned cluster tasks

Procedure

1. To delete all non-versioned cluster tasks and latest versioned cluster tasks, edit the TektonConfig custom resource definition (CRD) and set the clusterTasks parameter in spec.addon.params to false.

   Example TektonConfig CR

   apiVersion: operator.tekton.dev/v1alpha1
   kind: TektonConfig
   metadata:
     name: config
   spec:
     params:
     - name: createRbacResource
       value: "false"
     profile: all
     targetNamespace: openshift-pipelines
     addon:
       params:
       - name: clusterTasks
         value: "false"
   ...

   Copy to Clipboard Toggle word wrap

   When you disable cluster tasks, the Operator removes all the non-versioned cluster tasks and only the latest version of the versioned cluster tasks from the cluster.

   Note

   Re-enabling cluster tasks installs the non-versioned cluster tasks.

2. Optional: To delete earlier versions of the versioned cluster tasks, use any one of the following methods:

   1. To delete individual earlier versioned cluster tasks, use the oc delete clustertask command followed by the versioned cluster task name. For example:

      $ oc delete clustertask buildah-1-6-0

      Copy to Clipboard Toggle word wrap

   2. To delete all versioned cluster tasks created by an old version of the Operator, you can delete the corresponding installer set. For example:

      $ oc delete tektoninstallerset versioned-clustertask-1-6-k98as

      Copy to Clipboard Toggle word wrap
      Important

      If you delete an old versioned cluster task, you cannot restore it. You can only restore versioned and non-versioned cluster tasks that the current version of the Operator has created.
