Highlights

One major change completed in this release is #485 which migrates from typed client to generic controller-runtime client.

• Impact to end-users: N/A
• Impact to developers:
  • for CR object's manipulation, new plugin's development should stick to current codebase convention to use controller-runtime's client or informer
  • for core API object's manipulation, esp. Pods and Nodes, it's still recommended to read/watch from frameworkHandle's sharedInformerFactory; for other core API objects, it's up to plugin developers to choose which client to use
  • ⚠️ generated typed client/informer under pkg/generated will be removed after 3 releases (v0.30.x). External repos that vendor this repo's typed generation code should either generate typed client/informer themselves or start migrating to generic controller-runtime client. Updated: generated typed client/informer libs will still be maintained rather than removal due to demands from external community like kubeflow.

Documentation

• Init github page support (#616, @zwpaper).
• 📖 An experimental website is live at https://scheduler-plugins.sigs.k8s.io/

Bug or Regression

• Fix findSuitableCombination calculation logic for selecting a combination when it contains NUMA nodes without memory modules (#627, @283713406)
• Fix incorrect score calculation for NodeResourceTopology LeastNUMANodes scoring strategy when NUMA nodes ids are not sorted. (#623, @PiotrProkop)

Other (Cleanup or Flake)

• Bump go version to 1.20 and k8s deps to 1.27 (#608, @Huang-Wei)
• Fixing minor bugs:
  • correctly printing the value of a variable instead of the type of the value of a variable
  • removing unnecessary intermediate variable assignment (#612, @knarayan)
• Migrate coscheduling to use controller-runtime client (#652, @Huang-Wei)
• Migrate appGroup and networkTopology client to ctrl runtime (#522, @zwpaper)
• Migrate noderesourcetopology to ctrl runtime client (#655, @zwpaper)
• Migrate elasticquota/capacityscheduling to controller-runtime (#665, @Huang-Wei)

Uncategorized

• Add a new coscheduling plugin argument podGroupBackoffSeconds to configure backoff timer for failed PodGroup. User needs to explicitly specify a positive integer to enable this feature. (#559, @KunWuLuan)
• Bump builder image to go1.20 (#611, @zwpaper)
• Bump k8s deps to 1.27.6 (#639, @zwpaper)

v0.25.7

🌷 scheduler-plugins v0.25.7 images are available at registry.k8s.io:

• registry.k8s.io/scheduler-plugins/kube-scheduler:v0.25.7
• registry.k8s.io/scheduler-plugins/controller:v0.25.7

Highlighted below are the changes made since the previous release (v0.24.9):

⚠️ BREAKING CHANGES

• The API Group of CRD PodGroup and ElasticQuota is migrated to scheduling.x-k8s.io. The brand new installations don't need to do anything. Users migrating to this release need to do the following steps:
  • use kubectl replace -f <crds> to ensure new CRDs function well
  • migrate the labels - new label is using a style of *.scheduling.x-k8s.io/<label-name>, e.g., scheduling.x-k8s.io/pod-group
• Helm chart now leverages --namespace scheduler-plugins --create-namespace to consolidate both Helm release meta info and chart artifacts in the same namespace. Moreover, it enables users to customize the installation namespace.

⭐ Major changes:

• new ScoringStrategy LeastNUMANodes for NodeResourceTopologyMatch plugin that will score nodes based on how many NUMA nodes are required to satisfy resource requirements of given pod
• refactoring in NodeResourceTopologyMatch plugin
• support scheduler component config v1
• PodGroup and ElasticQuota now serve /status as a standard subresrouce
• (WIP) migrate to controller-runtime to replace typed clientset
• bumped the Kubernetes dependency to v1.25.7
