I. News

1.1 Recent Version Releases:

The current version of this repository is v1.32.3

1.2 Version Information:

The Kubernetes version released on March 11, 2025, introduces key updates detailed in the official CHANGELOG, with additional binary downloads available. For comprehensive information on new features and changes, users are encouraged to refer to the Kubernetes announce forum and the linked CHANGELOG.

II. Issues

2.1 Top 5 Active Issues:

We consider active issues to be issues that that have been commented on most frequently within the last week. Bot comments are omitted.

1. Support multiple CPU core groups in kubelet config: This issue requests the addition of support in kubelet configuration for allocating CPU resources based on multiple CPU core groups such as isolated cores, non-isolated cores, and reserved cores, allowing users to specify CPU allocation preferences through annotations or other mechanisms. The motivation behind this feature is to better meet application requirements by segregating CPU resources according to these core groupings, which is currently not supported in kubelet.

   • The comments discuss whether this request should be triaged as a feature enhancement or a formal KEP (Kubernetes Enhancement Proposal), noting that the concept of multiple CPU resource pools has been debated for years without consensus. It is acknowledged as a complex change requiring a KEP and a lengthy process, with suggestions to possibly extend or repurpose existing features like QOSReserved to address the problem.
   • Number of comments this week: 8

2. Why doesn't ResourceQuota support cluster-level configuration?: This issue addresses the lack of cluster-level configuration support in the ResourceQuota feature of Kubernetes, which currently only enforces resource limits at the namespace level. The user is seeking a way to limit the total number of resources across the entire cluster to prevent issues caused by excessive resource creation.

   • The comments clarify that ResourceQuota is intentionally designed for namespace-level control and does not guard cluster-scoped resources. Alternatives such as using extensible admission controllers and monitoring API server metrics are suggested as potential ways to implement cluster-wide resource limits, though no built-in solution currently exists. The user expresses appreciation and intends to continue following the discussion.
   • Number of comments this week: 6

3. Inability for Kubelet to clean a large number of containers during GC cycle: This issue describes a problem where kubelet fails to clean up a large number of exited containers during its garbage collection (GC) cycle due to a gRPC message size limit being exceeded, causing nodes to become "NotReady" in environments with many short-lived pods. The user reports that after the removal of the --maximum-dead-containers option, there is no way to force kubelet to trigger GC early, resulting in persistent GC failures when container counts reach around 18,500 on containerd.

   • The discussion highlights that the container GC runs every minute but appears ineffective or blocked, with logs showing repeated gRPC resource exhaustion errors when listing containers. Suggestions include adding debug logs to the GC function and checking metrics to confirm GC activity, while participants note the lack of clear tuning options for GC and recommend gathering more detailed kubelet logs and goroutine profiles to diagnose potential blocking or inefficiencies in the GC process.
   • Number of comments this week: 6

4. Make sig-node CI test coverage adhere to defined guidance: This issue addresses the need to ensure that the sig-node continuous integration (CI) test coverage aligns with the established guidance documented for sig-node tests. It involves auditing existing test job names and lanes for compliance, deciding on the usefulness of unspecified jobs or lanes, and updating both tests and documentation to remove obsolete guidance such as references to cgroupsv1.

   • The comments include labeling the issue with relevant SIG tags, assigning responsibility, discussing the need to verify if recent testing guidance affects previous plans, incorporating that information into the issue body for clarity, and marking the issue as triaged and accepted.
   • Number of comments this week: 5

5. Audit the code in the noderesources and dynamicresources scheduler plugins added for extended resource support by DRA: This issue requests an audit of the code within the noderesources and dynamicresources scheduler plugins that are protected by the DRAExtendedResource feature gate, aiming to improve readability and verify correctness before promoting the feature to beta. The author highlights difficulties in understanding the code as it currently stands and suggests adding more comments and clarifications during the review process.

   • The comments include a request to involve specific contributors for assistance, an offer from one contributor to help and be assigned the task, and the subsequent assignment of the issue to that contributor, indicating a collaborative approach to addressing the audit.
   • Number of comments this week: 4

2.2 Top 5 Stale Issues:

We consider stale issues to be issues that has had no activity within the last 30 days. The team should work together to get these issues resolved and closed as soon as possible.

1. Zone-aware down scaling behavior: This issue describes a problem with the horizontal pod autoscaler's scale-in behavior causing an uneven distribution of pods across availability zones, despite using topology spread constraints with a maxSkew of 1. Specifically, during scale-in events, one zone ends up with significantly fewer pods than expected, leading to high CPU usage on the lone pod in that zone and violating the intended balanced pod spread across zones.
2. apimachinery's unstructured converter panics if the destination struct contains private fields: This issue describes a panic occurring in the apimachinery's DefaultUnstructuredConverter when it attempts to convert an unstructured object into a destination struct that contains private (non-exported) fields. The reporter expects the converter to safely ignore these private fields instead of panicking, as this problem arises particularly with protobuf-generated gRPC structs that include private fields for internal state.
3. Integration tests for kubelet image credential provider: This issue proposes adding integration tests for the kubelet image credential provider, similar to the existing tests for client-go credential plugins. It suggests that since there are already integration tests for pod certificate functionality, implementing tests for the kubelet credential plugins would be a logical and beneficial extension.
4. conversion-gen generates code that leads to panics when fields are accessed after conversion: This issue describes a bug in the conversion-gen tool where it generates incorrect conversion code for structs that have changed field types between API versions, specifically causing unsafe pointer conversions instead of properly calling the conversion functions. As a result, accessing certain fields like ExclusiveMaximum after conversion leads to runtime panics, highlighting the need for conversion-gen to produce safe and correct code to prevent such crashes.
5. Failure cluster [ff7a6495...] TestProgressNotify fails when etcd in k/k upgraded to 3.6.2: This issue describes a failure in the TestProgressNotify test that occurs when the etcd component in the Kubernetes project is upgraded to version 3.6.2. The test times out after 30 seconds waiting on a result channel, with error logs indicating that the embedded etcd server fails to set up serving due to closed network connections and server shutdowns.

2.3 Open Issues

This section lists, groups, and then summarizes issues that were created within the last week in the repository.

Issues Opened This Week: 28

Summarized Issues:

• Resource Quota and Scheduling Limitations: Several issues highlight limitations in resource management and scheduling in Kubernetes. There is no support for cluster-level ResourceQuota, only namespace-level, which restricts controlling total cluster-wide resources and can lead to resource exhaustion. Additionally, scheduling problems include pods timing out due to load and external binding events failing to wake up waiting pods, causing unschedulable conditions.
• [issues/134720, issues/134859, issues/134878]

• Test Failures and Flakes: Multiple test-related issues report unexpected failures and flakes in Kubernetes tests. These include a failing TestWatchStreamSeparation due to incorrect bookmark checks, a flake in TestVolumeBinding where PVCs remain Pending, and audit requests to improve sig-node CI test coverage for consistency and compliance.
• [issues/134771, issues/134815, issues/134862]

• Command and Feature Parity Requests: There are requests to enhance kubectl and kubelet features for better usability and parity. This includes adding --udp and --sctp flags to kubectl create service for protocol support and enabling kubelet CPU allocation based on multiple core groups to improve resource segregation.
• [issues/134732, issues/134772]

• Dynamic Resource Allocation (DRA) Improvements: Several issues focus on improving DRA functionality and developer experience. Problems include incorrect resource kind pluralization causing List() failures, lack of request origin indication in ResourceClaim device configs, and proposals for a shared webhook package to simplify validating webhooks and reduce boilerplate.
• [issues/134751, issues/134789, issues/134792]

• Kubernetes Upgrade and API Behavior Changes: Upgrading Kubernetes versions can cause unintended side effects and validation errors. For example, upgrading from 1.33 to 1.34 triggers StatefulSet pod rollouts due to metadata field removal, and applying MutatingAdmissionPolicy in v1.33.4 causes validation errors on first attempts that do not occur in v1.34.0.
• [issues/134773, issues/134808]

• Security and Key Management Enhancements: There is a proposal to add a configurable Data Encryption Key (DEK) cache timeout in KMS v2 to improve security by automatically clearing cached keys after a set duration, enhancing control over key lifecycle management.
• [issues/134774]

• Scheduler Performance and Resource Management: Improvements to scheduler efficiency and resource management are proposed, including implementing sync.Pool to reduce garbage collection pressure and adding a kubelet oomwatcher that uses cgroups v2 instead of kernel logs to detect OOM kills in rootless environments.
• [issues/134813, issues/134832]

• API Server Watch and Event Handling Issues: Problems with the Kubernetes API server's watch streams and client event handling have been reported. The sendInitialEvents feature returns unexpected MODIFIED or DELETED events before the initial BOOKMARK event, and watch streams in large clusters end prematurely, causing "TOO OLD" errors and negating feature benefits.
• [issues/134831, issues/134837]

• Code Quality and Refactoring Requests: There are requests to audit and improve code quality in scheduler plugins protected by feature gates and to reconsider moving REST-related code between packages due to potential import path breakages and versioning concerns.
• [issues/134783, issues/134817]

• Concurrency and Panic Handling Issues: Issues have been raised about inappropriate use of fatal calls within goroutines in test files, which do not terminate the main process and may cause unexpected panics. Additionally, a potential data race in cert_rotation.go suggests improving thread safety by better handling of clientCert variable access.
• [issues/134728, issues/134877, issues/134876]

• Device Request Optimization for Init Containers: A proposal suggests that non-sidecar init containers should create a single device request reflecting the maximum quantity needed per DRA extended resource to avoid redundant multiple requests and improve efficiency during initialization.
• [issues/134880]

• Kubelet Garbage Collection and Proxy Bugs: Kubelet fails to garbage collect large numbers of short-lived containers due to gRPC message size limits after removal of a configuration option, causing nodes to become NotReady. Additionally, kube-proxy in IPVS mode has a bug where it fails to maintain necessary ipset entries for hairpin SNAT traffic, breaking Pod-to-Service connections on the same node.
• [issues/134750, issues/134884]

• Probe Testing Enhancements: There is a request to add an end-to-end test verifying that probes continue to function correctly when using ContainerRestartRules, following up on previous related changes to ensure stability.
• [issues/134799]

2.4 Closed Issues

This section lists, groups, and then summarizes issues that were closed within the last week in the repository. This section also links the associated pull requests if applicable.

Issues Closed This Week: 7

Summarized Issues:

• HostnameOverride Test Failures: Multiple issues report failing Kubernetes tests related to the HostnameOverride feature, where pods do not correctly set or report their hostname. These failures are linked to an upstream musl libc bug affecting IPv6-only environments and address availability errors in specific CI jobs, suggesting the problem is external to Kubernetes itself.
• issues/134737, issues/134804

• Dynamic Resource Allocation (DRA) Test Flakiness: A failing kubetest2.Test in the ci-node-e2e-containerd-1-7-dra job is caused by permission denied errors when killing containers, likely due to the dra.sock plugin socket not starting properly. This results in flaky test behavior that has persisted since early October 2025.
• issues/134819

• Data Race in Admission Plugin Tests: The TestPluginNotReady unit test intermittently fails due to a detected data race condition during concurrent access in the policy validating package. This flakiness affects the Kubernetes admission plugin's reliability in testing.
• issues/134828

• Security Vulnerability from Malformed YAML: A security issue was identified where a malformed YAML file can cause a denial-of-service attack by consuming excessive resources and crashing the system. This vulnerability requires immediate attention to prevent potential exploitation.
• issues/134843

• Flaky pull-kubernetes-cmd Test Investigation: The pull-kubernetes-cmd test showed flakiness over several weeks, particularly in run_pods_tests, but investigations revealed that failures were due to changes in pull requests rather than inherent test instability. Consequently, the issue was closed as not a true flake.
• issues/134853

• Critique of Cloud-Native Development Practices: A satirical issue highlights common pitfalls and anti-patterns in Kubernetes controller and webhook design, using humor to emphasize pragmatic and reality-based approaches over idealistic or overly complex solutions. This discussion serves as a cautionary perspective on best practices.
