Developer News
Marko Mudrinic was nominated as TL of SIG K8s-Infra, and Mario Fahlandt to co-chair SIG-ContribEx.
Release Schedule
It’s 1.32 Release Week! Just to make sure you noticed the release team put out an extra Release Candidate (also to fix two release blocking issues). With that, here’s a little taste of the new/alpha features in 1.32 according to the Enhancements Board:
Mutating Admission Policies based on CEL
Allow splitting stdout and stderr in container log stream
Resource limits at the pod level
The Topology scheduler knows about shared L3 caches
Statusz page and Flagz page for all core components
Fine-grained Node API authorizations
Supporting external signers for service account tokens
Windows gets CPU and Memory affinity
CBOR data format as a JSON alternative
Of course, there are tons more enhancements, and 30 features are graduating to Beta or Stable. Find out more, and download and try, when Kubernetes 1.32 comes out tommorrow.
In the meantime, we have a bunch of patch releases; 1.29.12, 1.30.8, 1.31.4 are now available, mainly containing a golang update.
Shoutouts
See the 2024 Kuberentes Contributor Award Recipients.
SIG Node wants to shoutout people who contributed extra time and effort for the 1.32 release coordination. SIG Node is a leader on number of KEPs proposed and merged every release and we were addressing feedback from previous releases by introducing a new (currently informal) role - KEPs wranglers. Please join me in thanking the wranglers: @Adrian Reber, @fromani, @haircommander, @Kevin Hannon, @Sohan, @Sreeram Venkitesh. And the approvers: @dawnchen, @derekwaynecarr, @klueska, @mrunalp, @Sergey Kanzhelev, @tallclair, @yujuhong
Ben gives a heartfelt thank you to @neolit123 for all of your help and contributions over the years. #kubeadm, #kind and more owe you a great debt. Thank you!

Exploring multi-tenancy for my Kubernetes learning platform, with Stefan Roman
https://kube.fm/multi-tenancy-stefan
Stefan Roman shares his experience building Labs4Grabs, a platform that gives students root access to Kubernetes clusters. He discusses the journey from evaluating simple namespace-based isolation to implementing full VM-based isolation with KubeVirt.
You will learn:
Why namespace isolation isn't sufficient for untrusted users and the limitations of tools like vCluster when running privileged workloads.
How to use KubeVirt to achieve complete workload isolation and the trade-offs.
Practical approaches to implementing network security with NetworkPolicies and managing resource allocation across multiple student environments.
Follow Stefan's journey from simple to complex isolation strategies, focusing on the technical decisions and trade-offs he encountered.
