Kueue v0.9.0-rc.1

Changes since v0.8.0:

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

• Changed the type of Pending events, emitted when a Workload can't be admitted, from Normal to Warning.

  Update tools that process this event if they depend on the event type. (#3264, @kebe7jun)

• Deprecated SingleInstanceInClusterQueue and FlavorIndependent status conditions.

the Admission check status conditions “FlavorIndependent” and “SingleInstanceInClusterQueue” are no longer supported by default.
If you were using any of these conditions for your external AdmissionCheck you need to enable the AdmissionCheckValidationRules feature gate.
For the future releases you will need to provide validation by an external controller. (#3254, @mszadkow)

• Promote MultiKueue API and feature gate to Beta. The MultiKueue feature gate is now beta and enabled by default.

The MultiKueue specific types are now part of the Kueue's v1beta1 API. v1alpha types are no longer supported. (#3230, @trasc)

• Promoted VisibilityOnDemand to Beta and enabled by default.

The v1alpha1 Visibility API is deprecated and will be removed in the next release. Please use v1beta1 instead. (#3008, @mbobrovskyi)

• Provides more details on the reasons for ClusterQueues being inactive.
  If you were watching for the reason CheckNotFoundOrInactive in the ClusterQueue condition, watch AdmissionCheckNotFound and AdmissionCheckInactive instead. (#3127, @trasc)
• The QueueVisibility feature and its corresponding API was deprecated.

The QueueVisibility feature and its corresponding API was deprecated and will be removed in the v1beta2. Please use VisibilityOnDemand (https://kueue.sigs.k8s.io/docs/tasks/manage/monitor_pending_workloads/pending_workloads_on_demand/) instead. (#3110, @mbobrovskyi)

Changes by Kind

Feature

• Add gauge metric admission_cycle_preemption_skips that reports the number of Workloads in a ClusterQueue
  that got preemptions candidates, but had to be skipped in the last cycle. (#2919, @alculquicondor)

• Add integration for Deployment, where each Pod is treated as a separate Workload. (#2813, @vladikkuzn)

• Add integration for StatefulSet where Pods are managed by the pod-group integration. (#3001, @vladikkuzn)

• Added FlowSchema and PriorityLevelConfiguration for Visibility API. (#3043, @mbobrovskyi)

• Added a new optional resource.transformations section to the Configuration API that enables limited customization
  of how the resource requirements of a Workload are computed from the resource requests and limits of a Job. (#3026, @dgrove-oss)

• Added a way to specify dependencies between job integrations. (#2768, @trasc)

• Best effort support for scenarios when the Job is created at the same time as prebuilt workload or momentarily before the workload. In that case an error is logged to indicate that creating a Job before prebuilt-workload is outside of the intended use. (#3255, @mbobrovskyi)

• CLI: Added EXEC TIME column on kueuectl list workload command. (#2977, @mbobrovskyi)

• CLI: Added list pods for a job command. (#2280, @Kavinraja-G)

• CLI: Use protobuf encoding for core K8s APIs in kueuectl. (#3077, @tosi3k)

This fixes a bug where a workload might not have the Flavors it was assigned in a previous scheduling cycle invalidated, when the resources in the Cohort had changed. This bug could occur when other ClusterQueues were deleted from the Cohort. (#2984, @gabesaba)

• Detect and enable support for job CRDs installed after Kueue starts. (#2574, @ChristianZaccaria)

• Exposed available ResourceFlavors from the ClusterQueue in the LocalQueue status. (#3143, @mbobrovskyi)

• Helm: Support the topologySpreadConstraints and PodDisruptionBudget (#3295, @woehrl01)

• Hierarchical Cohorts, introduced with the v1alpha1 Cohorts API, allow users to group resources in an arbitrary tree structure. Additionally, quotas and limits can now be defined directly at the Cohort level. See #79 for more details. (#2693, @gabesaba)

• Included visibility-api.yaml as a part of main.yaml (#3084, @mbobrovskyi)

• Introduce APIs for Topology Aware Scheduling. (#3235, @mimowo)

• Introduce the "kueue.x-k8s.io/pod-group-fast-admission" annotation to Plain Pod integration.

  If the PlainPod has the annotation and is part of the Plain PodGroup, the Kueue will admit the Plain Pod regardless of whether all PodGroup Pods are created. (#3189, @vladikkuzn)

• Introduce the new PodTemplate annotation kueue.x-k8s.io/workload, and label kueue.x-k8s.io/podset.
  The annotation and label are alpha-level and gated by the new TopologyAwareScheduling feature gate. (#3228, @mimowo)

Kueue v0.7.0

Changes since v0.6.0:

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

• Added CRD validation rules to AdmissionCheck.

  Requires Kubernetes 1.25 or newer (#1975, @IrvingMg)

• Added CRD validation rules to ClusterQueue.

  Requires Kubernetes 1.25 or newer (#1972, @IrvingMg)

• Added CRD validation rules to LocalQueue.

  Requires Kubernetes 1.25 or newer (#1938, @IrvingMg)

• Added CRD validation rules to ResourceFlavor.

  Requires Kubernetes 1.25 or newer (#1958, @IrvingMg)

• Added CRD validation rules to Workload.

  Requires Kubernetes 1.25 or newer (#2008, @IrvingMg)

• Increased the default value in the .waitForPodsReady.requeuingStrategy.backoffBaseSeconds to 60

  You can configure .waitForPodsReady.requeuingStrategy.backoffBaseSeconds as needed. (#2251, @mbobrovskyi)

• Upgrade RayJob API to v1

  If you use KubeRay older than v1.0.0, you'll have to upgrade your existing installation
  to KubeRay v1.0.0, or any more recent version, that supports KubeRay v1 APIs, for it to
  remain compatible with Kueue. (#1802, @astefanutti)

• When using admission checks, and they are not satisfied yet, the reason for the Admission condition with status=False is now
  UnsatisfiedChecks

  If you were watching for the reason NoChecks in the Admitted condition, use UnsatisfiedChecks instead. (#2150, @trasc)

API Change

• Make ClusterQueue queueingStrategy field mutable. The field can be mutated while there are pending workloads. (#1934, @mimowo)
• User can now pass parameters to ProvisioningRequest using job's annotations (#1869, @PBundyra)

Feature

• A new condition with type Preempted allows to distinguish different reasons for the preemption to happen (#1942, @mimowo)

• Add configuration to register Kinds as being managed by an external Kueue-compatible controller (#2059, @dgrove-oss)

• Add fair sharing when borrowing unused resources from other ClusterQueues in a cohort.

  Fair sharing is based on DRF for usage above nominal quotas.
  When fair sharing is enabled, Kueue prefers to admit workloads from ClusterQueues with the lowest share first.
  Administrators can enable and configure fair sharing preemption using a combination of two policies: LessThanOrEqualtoFinalShare, LessThanInitialShare.

  You can define a fair sharing weight for ClusterQueues. The weight determines how much of the unused resources each ClusterQueue can take in comparison to others. (#2070, @alculquicondor)

• Add metric evicted_workloads: the number of evicted workloads per 'cluster_queue' (#1955, @lowang-bh)

• Add recommended Kubernetes labels to uniquely identify Pods and other resources installed with Kueue.

• Helm: Allow configuration of custom annotations on Service and Deployment's Pod (#2030, @tozastation)

• Improve metrics related to workload's quota reservation and admission:

  • fix admission_wait_time_seconds - to measure the time to "Admitted" condition since creation time or last requeue (as opposed to the "QuotaReserved" condition as before)
  • add quota_reserved_wait_time_seconds - measures time to "QuotaReserved" condition since creation time, or last eviction time
  • add quota_reserved_workloads_total - counts the number of workloads that got admitted
  • admission_checks_wait_time_seconds - measures the time to admit a workload with admission checks since quota reservation
  • use longer buckets (up to 10240s) for histogram metrics: admission_wait_time_seconds, quota_reserved_wait_time_seconds, admission_checks_wait_time_seconds (#1977, @mbobrovskyi)

• Improve the kubectl output for workloads using admission checks. (#1991, @vladikkuzn)

• Make the PodsReady base delay for requeuing configurable (#2040, @mimowo)

• MuliKueue: Manage worker cluster unavailability (#1681, @trasc)

• MultiKueue: Add support for JobSet spec.managedBy field (#1870, @trasc)

• MultiKueue: Add the managedBy field to JobSets assigned to a ClusterQueue configured for MultiKueue (#2048, @vladikkuzn)

• MultiKueue: Add worker connection monitoring and reconnect (#1806, @trasc)

• Show fair share of a CQ in status and a metric (#2276, @mbobrovskyi)

• Updates in admission check messages are recorded as events for jobs/pods. (#2147, @pajakd)

• Workload finished reason replaced with succeeded and failed reasons (#2026, @vladikkuzn)

• You can configure Kueue to ignore container resources that match specified prefixes. (#2267, @pajakd)

• You can define AdmissionChecks per ResourceFlavor in the ClusterQueue API, using admissionChecksStrategy (#1960, @PBundyra)

Bug or Regression

• Avoid unnecessary preemptions when there are multiple candidates for preemption with the same admission timestamp (#1875, @alculquicondor)

• Change the default pprof port to 8083 to fix a bug that causes conflicting listening ports between pprof and the visibility server. (#2228, @amy)

• Check the containers limits for used resources in provisioning admission check controller and include them in the ProvisioningRequest as requests (#2286, @trasc)

• Do not default to suspending a job whose parent is already managed by Kueue (#1846, @astefanutti)

• Fix handling of eviction in StrictFIFO to ensure the evicted workload is in the head.
  Previously, in case of priority-based preemption, it was possible that the lower-priority
  workload might get admitted while the higher priority workload is being evicted. (#2061, @mimowo)

• Fix incorrect quota management when lendingLimit enabled in preemption (#1770, @kerthcet)

• Fix preemption algorithm to reduce the number of preemptions within a ClusterQueue when reclamation is not possible, and when using .preemption.borrowWithinCohort (#2110, @alculquicondor)

• Fix preemption algorithm to reduce the number of preemptions within a ClusterQueue when reclamation is not possible. (#1979, @mimowo)

• Fix preemption to reclaim quota that is blocked by an earlier pending Workload from another ClusterQueue in the same cohort. (#1866, @alculquicondor)

• Fix support for MPIJobs when using a ProvisioningRequest engine that applies updates only to worker templates. (#2265, @trasc)

• Fix the counter of pending workloads in cluster queue status.

  The counter would not count the head workload for StrictFIFO queues, if the workload cannot get admitted.

  This change also includes the blocked workload in the metrics and the visibility API for the list of pending workloads. (#1936, @mimowo)

• Fix the resource requests computation taking into account sidecar containers. (#2099, @IrvingMg)

• Helm: Fix a bug that prevented Kueue to work with the cert-manager. (#2087, @EladDolev)

• Helm: Fix a bug where the configuration for integrations.podOptions.namespaceSelector didn't have an effect due to indentation issues. (#2086, @EladDolev)

• Helm: Fix chart values configuration for the number of reconcilers for the Pod integration. (#2046, @alculquicondor)

• Kueue visibility API is no longer installed by default. Users can install it via helm or applying the visibility-api.yaml artifact. (#1746, @trasc)

• Make the defaults for PodsReadyTimeout backoff more practical, as for the original values
  the couple of first requeues made the impression as immediate on users (below 10s, which
  is negligible to the wait time spent waiting for PodsReady).

  The defaults values for the formula to determine the exponential back are changed as follows:

  • base 1s -> 10s
  • exponent:...

  Requires Kubernetes 1.25 or newer (#1975, @IrvingMg)

• Added CRD validation rules to ClusterQueue.

  Requires Kubernetes 1.25 or newer (#1972, @IrvingMg)

• Added CRD validation rules to LocalQueue.

  Requires Kubernetes 1.25 or newer (#1938, @IrvingMg)

• Added CRD validation rules to ResourceFlavor.

  Requires Kubernetes 1.25 or newer (#1958, @IrvingMg)

• Added CRD validation rules to Workload.

  Requires Kubernetes 1.25 or newer (#2008, @IrvingMg)

• Increased the default value in the .waitForPodsReady.requeuingStrategy.backoffBaseSeconds to 60

  You can configure .waitForPodsReady.requeuingStrategy.backoffBaseSeconds as needed. (#2251, @mbobrovskyi)

• Upgrade RayJob API to v1

  If you use KubeRay older than v1.0.0, you'll have to upgrade your existing installation
  to KubeRay v1.0.0, or any more recent version, that supports KubeRay v1 APIs, for it to
  remain compatible with Kueue. (#1802, @astefanutti)

• When using admission checks, and they are not satisfied yet, the reason for the Admission condition with status=False is now
  UnsatisfiedChecks

  If you were watching for the reason NoChecks in the Admitted condition, use UnsatisfiedChecks instead. (#2150, @trasc)

API Change

• Make ClusterQueue queueingStrategy field mutable. The field can be mutated while there are pending workloads. (#1934, @mimowo)
• User can now pass parameters to ProvisioningRequest using job's annotations (#1869, @PBundyra)

Feature

• A new condition with type Preempted allows to distinguish different reasons for the preemption to happen (#1942, @mimowo)

• Add configuration to register Kinds as being managed by an external Kueue-compatible controller (#2059, @dgrove-oss)

• Add fair sharing when borrowing unused resources from other ClusterQueues in a cohort.

  Fair sharing is based on DRF for usage above nominal quotas.
  When fair sharing is enabled, Kueue prefers to admit workloads from ClusterQueues with the lowest share first.
  Administrators can enable and configure fair sharing preemption using a combination of two policies: LessThanOrEqualtoFinalShare, LessThanInitialShare.

  You can define a fair sharing weight for ClusterQueues. The weight determines how much of the unused resources each ClusterQueue can take in comparison to others. (#2070, @alculquicondor)

• Add metric evicted_workloads: the number of evicted workloads per 'cluster_queue' (#1955, @lowang-bh)

• Add recommended Kubernetes labels to uniquely identify Pods and other resources installed with Kueue.
  The Deployment selector remains unchanged to allow for a seamless upgrade. (#1695, @astefanutti)

• Added validations for the ".internalCertManagement" in the Configuration. (#2169, @tenzen-y)

• Added validations for the "multiKueue.origin", ".multiKueue.gcInterval" and the "multiKueue.workerLostTimeout" in the Configuration. (#2129, @tenzen-y)

• Added validations for the "waitForPodsReady.timeout" in the Configuration. (#2214, @tenzen-y)

• Adds ObservedGeneration in conditions (#1939, @vladikkuzn)

• CLI: Added list workloads command. (#2195, @mbobrovskyi)

• CLI: Added pass-through commands support in kubectl-kueue for get, describe, edit, patch and delete. (#2181, @trasc)

• Helm: Allow configuration of ipFamilyPolicy for ipDualStack kubernetes cluster (#1933, @dongjiang1989)

• Helm: Allow configuration of custom annotations on Service and Deployment's Pod (#2030, @tozastation)

• Improve metrics related to workload's quota reservation and admission:

  • fix admission_wait_time_seconds - to measure the time to "Admitted" condition since creation time or last requeue (as opposed to the "QuotaReserved" condition as before)
  • add quota_reserved_wait_time_seconds - measures time to "QuotaReserved" condition since creation time, or last eviction time
  • add quota_reserved_workloads_total - counts the number of workloads that got admitted
  • admission_checks_wait_time_seconds - measures the time to admit a workload with admission checks since quota reservation
  • use longer buckets (up to 10240s) for histogram metrics: admission_wait_time_seconds, quota_reserved_wait_time_seconds, admission_checks_wait_time_seconds (#1977, @mbobrovskyi)

• Improve the kubectl output for workloads using admission checks. (#1991, @vladikkuzn)

• Make the PodsReady base delay for requeuing configurable (#2040, @mimowo)

• MuliKueue: Manage worker cluster unavailability (#1681, @trasc)

• MultiKueue: Add support for JobSet spec.managedBy field (#1870, @trasc)

• MultiKueue: Add the managedBy field to JobSets assigned to a ClusterQueue configured for MultiKueue (#2048, @vladikkuzn)

• MultiKueue: Add worker connection monitoring and reconnect (#1806, @trasc)

• Pod Integration: Add condition WaitingForReplacementPods to Workloads of pod groups with incomplete number of pods (#2234, @mbobrovskyi)

• Pod Integration: Improve performance (#1952, @gabesaba)

• Pod Integration: The reason for stopping a pod is now specified in the pod TerminationTarget condition (#2160, @pajakd)

• ProvisioningRequest: Graduated to Beta and enabled by default (#1968, @pajakd)

• ProvisioningRequest: Propagate the message for a ProvisioningRequest being provisioned (which might include an ETA, depending on the implementation) to the Workload status (#2007, @pajakd)

• Show fair share of a CQ in status and a metric (#2276, @mbobrovskyi)

• Updates in admission check messages are recorded as events for jobs/pods. (#2147, @pajakd)

• Workload finished reason replaced with succeeded and failed reasons (#2026, @vladikkuzn)

• You can configure Kueue to ignore container resources that match specified prefixes. (#2267, @pajakd)

• You can define AdmissionChecks per ResourceFlavor in the ClusterQueue API, using admissionChecksStrategy (#1960, @PBundyra)

Bug or Regression

• Avoid unnecessary preemptions when there are multiple candidates for preemption with the same admission timestamp (#1875, @alculquicondor)

• Change the default pprof port to 8083 to fix a bug that causes conflicting listening ports between pprof and the visibility server. (#2228, @amy)

• Check the containers limits for used resources in provisioning admission check controller and include them in the ProvisioningRequest as requests (#2286, @trasc)

• Do not default to suspending a job whose parent is already managed by Kueue (#1846, @astefanutti)

• Fix handling of eviction in StrictFIFO to ensure the evicted workload is in the head.
  Previously, in case of priority-based preemption, it was possible that the lower-priority
  workload might get admitted while the higher priority workload is being evicted. (#2061, @mimowo)

• Fix incorrect quota management when lendingLimit enabled in preemption (#1770, @kerthcet)

• Fix preemption algorithm to reduce the number of preemptions within a ClusterQueue when reclamation is not possible, and when using .preemption.borrowWithinCohort (#2110, @alculquicondor)

• Fix preemption algorithm to reduce the number of preemptions within a ClusterQueue when reclamation is not possible. (#1979, @mimowo)

• Fix preemption to reclaim quota that is blocked by an earlier pending Workload from another ClusterQueue in the same cohort. (#1866, @alculquicondor)

• Fix support for MPIJobs when using a ProvisioningRequest engine that applies updates only to worker templates. (#2265, @trasc)

• Fix the counter of pending workloads in cluster queue status.

  The counter would not count the head workload for StrictFIFO queues, if the workload cannot get admitted.

  This change also includes the blocked workload in the metrics and the visibility API for the list of pending workloads. (#1936, @mimowo)

• Fix the resource requests computation taking into account sidecar containers. (#2099, @IrvingMg)

• Helm: Fix a bug that prevented Kueue to work with the cert-manager. (#2087, @EladDolev)

• Helm: Fix a bug where the configuration for integrations.podOptions.namespaceSelector didn't have an effect due to indentation issues. (#2086, @EladDolev)

• Helm: Fix chart values configuration for the number of reconcilers for the Pod integration. (#2046, @alculquicondor)

• Kueue visibility API is no longer installed by default. Users can install it via helm or applying the visibility-api.yaml artifact. (#1746, @trasc)

• Make the defaults for PodsReadyTimeout backoff more practical, as for the original values
  the couple of first requeues made the impression as immediate on users (below 10s, which
  is negligible to the wait time spent waiting for PodsReady).

  The defaults values for the formula to determine the exponential back are changed as follows:

  • base 1s -> 10s
  • exponent: 1.41284738 -> 2
    So, now the consecutive times to requeue a workload are...
