Developer News
VM images built with Kubernetes Image Builder older than v0.1.37 have a security hole that may allow remote login. This includes Proxmox, Nutanix, OVA, QEMU, and raw providers. Upgrade to v0.1.38 or later, and rebuild your VM images.
SIG-Release is planning to phase out artifacts for some architectures by 1.33. In 1.32, the updated cross-build images for ppc64le and s390x will not be released, because of broken dependencies.
Release Schedule
Next Deadline: Docs placeholder PRs deadline, October 24
The enhancements freeze was last week and we have a total of 60 KEPs tracked for v1.32. 9 enhancements did not make the cut for the enhancements freeze and 9 were deferred. Coming up next is the deadline for getting your docs placeholder PRs open, on 24th of October. If your KEP is tracked for v1.32 and if you have updates to the docs, don’t forget to open your PRs in time!
The patch releases planned for October have been moved to Tuesday, October 22, 2024.
Featured PRs
This PR updates the scheduler scoring process to consider the resource requests of existing sidecar containers when scheduling Pods. As per the sidecar containers KEP, resources calculations for scheduling pods with sidecars is supposed to be: Max(Max( each InitContainerUse ), Sum(Sidecar Containers) + Sum(Containers)), but existing scheduler logic was using Max(RegularContainers, InitContainers) to calculate resources instead. This PR updates this logic.
KEP of the Week
KEP 3104: Introduce kuberc
This KEP proposes to introduce a new kuberc file that can be used to separate cluster credentials and server configuration from user preferences. This new and entirely opt-in kuberc file would allow users to configure aliases and default flags and also aims to deprecate the kubeconfig Preferences field. While in alpha, this feature can be enabled by setting the KUBECTL_KUBERC environment variable to true. The file will default to being located in ~/.kube/kuberc. A flag will allow overriding this default location with a path i.e. kubectl –kuberc /var/kube/rc.
This KEP is tracked for alpha release in the ongoing v1.32 cycle.

Declarative configuration and the Kubernetes Resource Model, with Brian Grant
This episode offers a rare glimpse into the design decisions that shaped the world's most popular container orchestration platform.
Brian Grant, CTO of ConfigHub and former tech lead on Google's Borg team, discusses the Kubernetes Resource Model (KRM) and its profound impact on the Kubernetes ecosystem.
He explains how KRM's resource-centric API patterns enable Kubernetes' flexibility and extensibility and how they have influenced the entire cloud native landscape.
You will learn:
How the Kubernetes API evolved from inconsistency to a uniform structure, enabling support for thousands of resource types.
Why Kubernetes' self-describing resources and Server-side Apply simplify client implementations and configuration management.
The evolution of Kubernetes configuration tools like Helm, Kustomize, and GitOps solutions.
Current trends and future directions in Kubernetes configuration, including potential AI-driven enhancements.
