2.9. Managing jobs and workloads


Red Hat build of Kueue does not directly manipulate jobs that are created by users. Instead, Kueue manages Workload objects that represent the resource requirements of a job. Red Hat build of Kueue automatically creates a workload for each job, and syncs any decisions and statuses between the two objects.

The Red Hat build of Kueue Operator uses an opt-in webhook mechanism to ensure that policies are only enforced for the jobs and namespaces that it is expected to target.

You must label the namespaces where you want Red Hat build of Kueue to manage jobs with the kueue.openshift.io/managed=true label.

Prerequisites

  • You have cluster administrator permissions.
  • The Red Hat build of Kueue Operator is installed on your cluster, and you have created a Kueue custom resource (CR).
  • You have installed the OpenShift CLI (oc).

Procedure

  • Add the kueue.openshift.io/managed=true label to a namespace by running the following command:

    $ oc label namespace <namespace> kueue.openshift.io/managed=true

When you add this label, you instruct the Red Hat build of Kueue Operator that the namespace is managed by its webhook admission controllers. As a result, any Red Hat build of Kueue resources within that namespace are properly validated and mutated.
