Setup manageJobsWithoutQueueName

This page describes how to configure Kueue to ensure that all Workloads submitted in namespaces intended for use by batch users will be managed by Kueue even if they lack a kueue.x-k8s.io/queue-name label.

Before you begin

Learn how to install Kueue with a custom manager configuration.

Configuration

You will need to modify the manage configuration to set manageJobsWithoutQueueName to true.

If you also modify the default configuration to enable the Pod, Deployment or StatefulSet integrations, you may also need to override the default value of managedJobsNamespaceSelector to limit the scope of manageJobsWithoutQueueName to only apply to batch user namespaces.

The default value for managedJobsNamespaceSelector is

matchExpressions:
- key: kubernetes.io/metadata.name
  operator: NotIn
  values: [ kube-system, kueue-system ]

This dafault value exempts the kube-system and kueue-system namespaces from management; all other namespaces will be managed by Kueue when manageJobsWithoutQueueName is true.

Alternatively, the batch administrator can label namespaces that are intended for batch users and define a selector that matches only those namespaces. For example,

managedJobsNamespaceSelector:
  matchLabels:
    kueue.x-k8s.io/managed-namespace: true

Expected Behavior

In all namespaces that match the namespace selector, any Workloads submitted without a kueue.x-k8s.io/queue-name label will be suspended. These Workloads will not be considered for admission by Kueue until they are edited to have a kueue.x-k8s.io/queue-name label.
