Developer News

The second New Contributor Orientations will take place on October 15th. Please recommend them to the aspiring new contributor in your life.

Due to dependency changes in Debian LTS images, SIG-Release is proposing to stop building artifacts for some architectures. Discussions continue in SIG-Release.

Aldo Culquicondor has stepped down from WG Batch chair, and has nominated Kevin Hannon to take his place.

The NA Contributor Summit schedule is live. Remember to register, and if you’re going consider volunteering to help run the Summit.

Release Schedule

Next Deadline: Enhancements Freeze, October 10

We’re in the final week for Enhancement Opt-In. Please check your features on the project board and make sure their status is correct; if not, get in touch with your SIG lead ASAP.

Speaking of deadlines, patch release cherry picks for the October patches are due Friday.

KEP of the Week

KEP-3973: Consider Terminating Pods in Deployments

This KEP updates how the Deployment controller behaves when reporting Pod count when Pods are in terminating state. Currently Deployments have inconsistent behaviour in how the terminating Pods are handled based on the rollout strategy. This KEP introduces a new .spec.podReplacementPolicy with which users can configure this behaviour. This is similar to the spec.podReplacementPolicy in the Job spec and allows users to define if the Deployment should wait for its Pods to terminate before creating new Pods or if it should create them immediately.

This KEP is tracked for alpha in the ongoing v1.32 release.

Other Merges

The NestedNumberAsFloat64 method converts int64 values to float64 when accessing numbers in unstructured objects

Assert the flag behavior on kube-proxy using unit test

API impact verification: Added a new -b flag for explicitly requesting build checks

DRA Scheduler: mock workqueue for controller unit test

Prevent a race condition from causing erroneous volume unmounts for flex volume plugins on kubelet restart

Use generics for Workqueue metrics

kubectl apply --server-side now supports --subresource

In TestCoreResourceEnqueue, verify whether Pods are requeued to the activeQ after specific cluster events are triggered

Fixed: TestPersistentVolumeProvisionMultiPVCs

MVP cleanup #2

New Tests: dra helper function, TestGenerateLinuxContainerResources, VolumeGroupSnapshot

The scheduler adds QueueingHint in the VolumeBinding plugin’s CSIDriver event

system-reserved-compressible and kube-reserved-compressible to set only compressible (e.g. CPU) type resources on system and kube reserved slice respectively

Reduce memory usage/allocations during wait for volume attachment

Version Updates

After increasing golang versions to 1.23.1 and 1.22.7, revert back to 1.23.0 until the question of alternate architectures is resolved.

GPUs in Kubernetes for AI Workloads

Today we dive into running AI models on Kubernetes with GPU support. Learn how to manage GPUs in Kubernetes clusters, create GPU nodes, and optimize resource usage without breaking the bank. We'll walk you through setting up a Google Cloud Kubernetes cluster (the same logic should apply to other Cloud providers), deploying AI models like Ollama's Llama2, and handling GPU partitioning. Watch now to master GPU-based AI workloads in Kubernetes!

KEP of the Week

KEP-4815: DRA: Add support for partitionable devices

One of the original use cases of DRA was to dynamically create and allocate partitions of a full GPU device on demand. As DRA evolved into “structured parameters” this ability to dynamically partition devices has been lost. This KEP proposes introducing the ability for “structured parameters” DRA to allocate both full devices and fixed-size partitions of full devices (across multiple dimensions). This is planned to be done by introducing a new type called PartitionableDevice which would have all the same fields as BasicDevice plus two new fields Includes and ConsumesCapacityFrom. With these new fields, the scheduler has everything it needs to support the dynamic allocation of both full devices and their fixed-size partitions.

This KEP is aiming for alpha in the ongoing v1.32 release cycle.
