## v0.6.0 | ||
|
||
Changes since `v0.5.0`: | ||
|
||
### API Change | ||
|
||
- A `stopPolicy` field in the ClusterQueue allows to hold or drain a ClusterQueue (#1299, @trasc) | ||
- Add a lendingLimit field in ClusterQueue's quotas, to allow restricting how much of the unused resources by the ClusterQueue can be borrowed by other ClusterQueues in the cohort. | ||
In other words, this allows a quota equal to `nominal-lendingLimit` to be exclusively used by the ClusterQueue. (#1385, @B1F030) | ||
- Add validation for clusterQueue: when cohort is empty, borrowingLimit must be nil. (#1525, @B1F030) | ||
- Allow decrease reclaimable pods to 0 for suspended job (#1277, @yaroslava-serdiuk) | ||
- MultiKueue: Add Path location type for cluster KubeConfigs. (#1640, @trasc) | ||
- MultiKueue: Add garbage collection of deleted Workloads. (#1643, @trasc) | ||
- MultiKueue: Multi cluster job dispatching for k8s Job. This doesn't include support for live status updates. (#1313, @trasc) | ||
- Support for a mechanism to suspend a running Job without requeueing (#1252, @vicentefb) | ||
- Support for preemption while borrowing (#1397, @mimowo) | ||
- The leaderElection field in the Configuration API is now defaulted. | ||
Leader election is now enabled by default. (#1598, @astefanutti) | ||
- Visibility API: Add an endpoint that allows a user to fetch information about pending workloads and their position in LocalQueue. (#1365, @PBundyra) | ||
- Visibility API: Introduce an on-demand API endpoint for fetching pending workloads in a ClusterQueue. (#1251, @PBundyra) | ||
- Visibility API: extend the information returned for the pending workloads in a ClusterQueue, including the workload position in the queue. (#1362, @PBundyra) | ||
- WaitForPodsReady: Add a config field to allow admins to configure the timestamp used when sorting workloads that were evicted due to their Pods not becoming ready on time. (#1542, @nstogner) | ||
- WaitForPodsReady: Support a backoff re-queueing mechanism with configurable limit. (#1709, @tenzen-y) | ||
|
||
### Feature | ||
|
||
- Add Prebuilt Workload support for JobSets. (#1575, @trasc) | ||
- Add events for transitions of the provisioning AdmissionCheck (#1271, @stuton) | ||
- Add prebuilt workload support for batch/job. (#1358, @trasc) | ||
- Add support for groups of plain Pods. (#1319, @achernevskii) | ||
- Allow configuring featureGates on helm charts. (#1314, @B1F030) | ||
- At log level 6, the usage of ClusterQueues and cohorts is included in logs. | ||
|
||
The status of the internal cache and queues is also logged on demand when a SIGUSR2 is sent to kueue, regardless of the log level. (#1528, @alculquicondor) | ||
- Changing tolerations in an inadmissible job triggers an admission retry with the updated tolerations. (#1304, @stuton) | ||
- Increase the default number of reconcilers for Pod and Workload objects to 5, each. (#1589, @alculquicondor) | ||
- Jobs preserve their position in the queue if the number of pods change before being admitted (#1223, @yaroslava-serdiuk) | ||
- Make the image build setting CGO_ENABLED configurable (#1391, @anishasthana) | ||
- MultiKueue: Add live status updates for multikueue JobSets (#1668, @trasc) | ||
- MultiKueue: Support for JobSets. (#1606, @trasc) | ||
- Support RayCluster as a queue-able workload in Kueue (#1520, @vicentefb) | ||
- Support for retry of provisioning request. | ||
|
||
When `ProvisioningACC` is enabled, and there are existing ProvisioningRequests, they are going to be recreated. | ||
This may cause job evictions for some long-running jobs which were using the ProvisioningRequests. (#1351, @mimowo) | ||
- The image gcr.io/k8s-staging-kueue/debug:main, along with the script ./hack/dump_cache.sh can be used to trigger a dump of the internal cache into the logs. (#1541, @alculquicondor) | ||
- The priority sorting within the cohort could be disabled by setting the feature gate PrioritySortingWithinCohort to false (#1406, @yaroslava-serdiuk) | ||
- Visibility API: Add HA support. (#1554, @astefanutti) | ||
|
||
### Bug or Regression | ||
|
||
- Add Missing RBAC on finalizer sub-resources for job integrations. (#1486, @astefanutti) | ||
- Add Mutating WebhookConfigurations for the AdmissionCheck, RayJob, and JobSet to helm charts (#1567, @B1F030) | ||
- Add Validating/Mutating WebhookConfigurations for the KubeflowJobs like PyTorchJob (#1460, @tenzen-y) | ||
- Added event for QuotaReserved and fixed event for Admitted to trigger when admission checks complete (#1436, @trasc) | ||
- Avoid finished Workloads from blocking quota after a Kueue restart (#1689, @trasc) | ||
- Avoid recreating a Workload for a finished Job and finalize a job when the workload is declared finished. (#1383, @achernevskii) | ||
- Do not (re)create ProvReq if the state of admission check is Ready (#1617, @mimowo) | ||
- Fix Kueue crashing at the log level 6 when re-admitting workloads (#1644, @mimowo) | ||
- Fix a bug in the pod integration that unexpected errors will occur when the pod isn't found (#1512, @achernevskii) | ||
- Fix a bug that plain pods managed by kueue will remain in a terminating state, due to a finalizer (#1342, @tenzen-y) | ||
- Fix client-go libraries bug that can not operate clusterScoped resources like ClusterQueue and ResourceFlavor. (#1294, @tenzen-y) | ||
- Fix fungibility policy `Preempt` where it was not able to utilize the next flavor if preemption was not possible. (#1366, @alculquicondor) | ||
- Fix handling of preemption within a cohort when there is no borrowingLimit. In that case, | ||
during preemption, the permitted resources to borrow were calculated as if borrowingLimit=0, instead of unlimited. | ||
|
||
As a consequence, when using `reclaimWithinCohort`, it was possible that a workload, scheduled to ClusterQueue with no borrowingLimit, would preempt more workloads than needed, even though it could fit by borrowing. (#1561, @mimowo) | ||
- Fix the synchronization of the admission check state based on recreated ProvisioningRequest (#1585, @mimowo) | ||
- Fixed fungibility policy `whenCanPreempt: Preempt`. The admission should happen in the flavor for which preemptions were issued. (#1332, @alculquicondor) | ||
- Kueue replicas are advertised as Ready only once the webhooks are functional. | ||
|
||
This allows users to wait with the first requests until the Kueue deployment is available, so that the | ||
early requests don't fail. (#1676, @mimowo) | ||
- Pending workload from StrictFIFO ClusterQueue doesn't block borrowing from other ClusterQueues (#1399, @yaroslava-serdiuk) | ||
- Remove deleted pending workloads from the cache (#1679, @astefanutti) | ||
- Remove finalizer from Workloads that are orphaned (have no owners). (#1523, @achernevskii) | ||
- Trigger an eviction for an admitted Job after an admission check changed state to Rejected. (#1562, @trasc) | ||
- Webhooks are served in non-leading replicas (#1509, @astefanutti) | ||
|
||
### Other (Cleanup or Flake) | ||
|
||
- Expose utilization functions to setup jobframework reconcilers and webhooks (#1630, @tenzen-y) |
