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 consult 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. unit-master-golang-tip broke spectaularly!: This issue reports a breakage in the Kubernetes unit tests caused by a recent commit to the Go language repository, specifically related to protobuf handling that results in a gzip checksum panic. The discussion investigates the root cause, comparing good and bad Go commits, considering hardware differences like CPU instruction sets, and ultimately identifies a specific Go commit that introduced the failure, with a linked upstream Go issue filed for resolution.

   • The comments analyze the failure by comparing Go and Kubernetes commit diffs, discuss inability to reproduce locally possibly due to CPU architecture differences, identify a Go commit involving hashing as the culprit, confirm the breakage with multiple test logs, and link to related Go issues while suggesting testing with the latest Go release candidate.
   • Number of comments this week: 12

2. List available endpoints for kube-controller-manager's /statusz : This issue requests the addition of a list of available endpoints for the kube-controller-manager's /statusz path, including "/livez", "/readyz", "/healthz", and "/metrics". It is a sub-issue related to a larger Kubernetes project and is tagged for the instrumentation special interest group (SIG).

   • The comments show the issue was triaged and accepted, with multiple suggestions to label it as a good first issue and offers of help, followed by repeated assignment commands indicating attempts to take ownership of the task.
   • Number of comments this week: 7

3. Failed to destroy network for pod from CNI network after reboot: This issue describes a problem where a DaemonSet pod fails to be properly terminated and removed from the Cilium CNI network after a node reboot, causing the pod to get stuck in a terminating state and preventing new pods from starting on that node. The error occurs because the network namespace (netns) associated with the pod cannot be found during the CNI DEL operation, leading to a failure in destroying the pod’s network sandbox.

   • The comments identify this as a complex and known challenge related to node reboots and CNI lifecycle handling, particularly with Cilium and device plugins like Nvidia’s. Contributors suggest the problem likely stems from lost network namespace context after reboot, recommend investigating kubelet and CRI-O logs for more insight, and note that this issue is not unique to Nvidia but also reproducible with other images; the discussion concludes with sharing logs and a suggestion to follow up in the Cilium project since Kubernetes itself has limited control over CNI plugin internals.
   • Number of comments this week: 6

4. After getting UserNamespaces configured and setting idsPerPod, the uid/gid maps inside containers are not seeing the settings propagate: This issue describes a problem where configuring UserNamespaces with a higher idsPerPod value in the kubelet does not propagate correctly to containers, which remain limited to the default 65536 UID/GID mappings despite the configuration showing as updated on the node. The user is seeking clarification on how these settings should propagate to containers, whether the limit applies per pod or per container, and what might be missing from the documentation to achieve the expected behavior of expanded UID/GID ranges inside pods.

   • The comments discuss whether the idsPerPod setting is applied or ignored, confirming that containers in a pod should share the same user namespace and UID range. It is acknowledged that the observed behavior is likely a bug, with debug logs showing the kubelet still using the default 65536 value instead of the configured 1048576, indicating the configuration is not being properly read or applied.
   • Number of comments this week: 6

5. Deprecated Usage of strings.Title in ServiceCheck.Name(): This issue addresses the deprecated usage of the strings.Title function in the ServiceCheck.Name() method within the Kubernetes codebase, recommending its replacement with the Unicode- and locale-aware cases.Title from the golang.org/x/text/cases package. It highlights the correctness and future-proofing benefits of this change despite some performance overhead, and proposes auditing the codebase for similar deprecated usages and adding relevant test coverage.

   • The comments discuss the scope of strings.Title usage across multiple files, noting that some occurrences are in vendor directories and can be ignored, while others require replacement grouped by SIG ownership. Contributors seek guidance on triage and PR organization, emphasizing the need to coordinate changes across different SIGs and consider benchmarking for certain replacements.
   • Number of comments this week: 6

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. apimachinery resource.Quantity primitive values should be public for recursive hashing: This issue addresses the problem that the primitive values within the API Machinery resource.Quantity struct are private, which prevents recursive hashing libraries from accurately detecting changes in these quantities when hashing custom resource definitions (CRDs). The requester highlights that this limitation complicates change detection in scenarios like spec-drift detection for resource reservations, and suggests making these values public or providing a public representation to improve native support for such workflows.
2. APF borrowing by exempt does not match KEP: This issue highlights a discrepancy between the Kubernetes Enhancement Proposal (KEP) and the actual implementation regarding how the exempt priority level calculates its borrowing of concurrency limits in the API Priority and Fairness (APF) system. Specifically, the implementation does not apply the special borrowing rules for exempt priorities described in the KEP, resulting in the exempt priority level receiving a minimum concurrency limit of zero, which deviates from the intended behavior outlined in the design document.
3. 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 notably with protobuf-generated gRPC structs that include private fields for internal state, causing the conversion to fail even when only public fields are present in the unstructured data.
4. Jsonpath impl does not support left match regex: This issue requests the addition of support for the =~ operator in jsonpath filter expressions, enabling regex matching based on Golang regular expressions within jsonpath queries. The user highlights that this feature would simplify locating specific resources among many by allowing case-insensitive and pattern-based filtering, and they have expressed willingness to contribute an implementation. Since there were fewer than 5 open issues, all of the open issues have been listed above.

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: 34

Summarized Issues:

• Container Lifecycle Hook Testing Issues: The current end-to-end tests for Container Lifecycle Hook and Restartable Init Container Lifecycle Hook rely on an unusual scenario where lifecycle hooks perform HTTP/TCP requests to a different pod. This approach conflicts with upcoming security changes restricting the .host field to localhost and raises concerns about the practical use cases and reliability of these tests.
• issues/133091

• Pod Preemption and Eviction Problems: Using PriorityClass for pod preemption can cause immediate eviction of multiple lower-priority pods without respecting rolling update strategies or PodDisruptionBudgets. This behavior leads to potential downtime instead of a graceful, one-at-a-time eviction process.
• issues/133102

• Test Server Parallel Start Flakiness: The kubeapiserverapptesting.StartTestServer function currently cannot handle parallel starts without causing test flakiness. Fixing this issue may require significant refactoring due to dependencies on global state.
• issues/133106

• Security Vulnerability in Image Builder: Kubernetes Image Builder versions up to v0.1.44 have a high-severity security vulnerability (CVE-2025-7342) where Windows VM images built with Nutanix or OVA providers use default administrator credentials if not overridden. This flaw potentially allows unauthorized root access to affected nodes.
• issues/133115

• Device Resource Allocator Health Timeout Configuration: The timeout duration for marking a Device Resource Allocator (DRA) device's health status as "Unknown" is currently hardcoded to 30 seconds. There is a request to make this timeout configurable per plugin to accommodate varying hardware health-reporting characteristics, as introduced by KEP-4680.
• issues/133118

• Pod Scheduling with Multiple Storage Volumes: Pods with multiple storage volumes can remain pending if one volume binds successfully but another fails due to insufficient disk space. This issue suggests exploring more precise scheduling based on available storage to prevent such failures.
• issues/133121

• Preferred Storage Version Updates: There are proposals to update the preferred storage version to v1 in Kubernetes 1.35 for more objects in etcd and specifically for the VolumeAttributesClass. These updates follow the introduction of resource.k8s.io/v1 in version 1.34.
• issues/133131, issues/133160

• Kubelet Shutdown Race Condition: A race condition exists where systemd-logind configuration reload does not complete before the kubelet shutdown manager updates InhibitDelayMaxSec. This causes the shutdown inhibitor to fail to register properly, preventing the shutdown manager from functioning as intended.
• issues/133133

• User Namespace ID Mapping Bug: Despite configuring the kubelet with a higher idsPerPod value, UID/GID mappings inside containers remain limited to the default 65,536 IDs. This indicates the updated setting is not propagating correctly, suggesting a potential bug in kubelet or CRI-O.
• issues/133144

• Stateful Workload Testing Enhancement: A proposal exists to add a stateful workload simulating a toy database with strict upgrade and readiness conditions. This aims to enhance testing of StatefulSet behaviors and ensure robustness during upgrades.
• issues/133151

• Deprecated Function Replacement: The deprecated strings.Title function used in ServiceCheck.Name() should be replaced with cases.Title from golang.org/x/text/cases for correct Unicode and locale-aware title casing. A codebase audit for similar deprecated usages and performance considerations is also proposed.
• issues/133154

• Autoscaler Contract and API Stability: Requests include moving the AllocatedState type to the framework package and formally defining the scheduler/autoscaler contract for DRA consumable capacity. These changes aim to improve visibility, stability, and review processes to prevent unnoticed breaking changes affecting Cluster Autoscaler and kube-scheduler integration.
• issues/133161, issues/133162

• Dynamic Load Balancer Membership Trigger: There is a request to trigger the "EnsureLoadBalancer" method whenever Kubernetes node labels are updated. This enables dynamic load balancer pool membership based on node label selectors, improving traffic routing and health checks, especially for OpenStack Octavia LBaaS.
• issues/133165

• Core Dump Location Issue: Coredump files sometimes appear on the host's /var/crash directory instead of the intended persistent volume path inside the container, despite a softlink redirecting core dumps to the mounted persistent volume.
• issues/133169

• Deprecated ErrWaitTimeout Replacement: The deprecated ErrWaitTimeout method should be replaced with the recommended alternative across multiple packages beyond client-go and kubectl to ensure consistent code updates.
• issues/133175

• Null Pointer Dereference Risk: A potential null pointer dereference exists in csi_attacher.go where spec.PersistentVolume is dereferenced without a nil check, leading to a DEREF_AFTER_NULL error detected by static analysis.
• issues/133177

• Statusz Endpoint Enhancements: Requests have been made to add lists of available endpoints such as /livez, /readyz, /healthz, and /metrics to the /statusz paths of kube-controller-manager, kubelet, and kube-proxy. These are sub-issues linked to a larger Kubernetes project discussion.
• issues/133182, issues/133184, issues/133185

• Kubelet CSI Attachment Stress Test: A new stress test is proposed to verify kubelet behavior when the CSI attachment limit is exceeded, required for graduating the MutableCSINodeAllocatableCount feature to Beta by default.
• issues/133188

• API Ownership and Approval Process: Expanding ownership coverage and refactoring files involved in API changes is proposed to ensure mechanical and auto-generated modifications receive appropriate API approver permissions, improving the approval process for API promotions.
• issues/133189

• PodLevelResources and DRA Interaction Clarification: Clarification and definition of interaction and precedence rules between PodLevelResources API and Device Resource Allocation (DRA) system are requested. This addresses handling pod specs with both pod-level and container-level resource claims to ensure smooth PodLevelResources beta transition and GA.
• issues/133194

• Kubectl Pod Labeling Feature: A feature request proposes allowing users to label pods directly when creating deployments imperatively with kubectl, improving usability by enabling commands like kubectl create deployment deployment-1 --image=nginx --pod-labels=app=frontend,version=v1.
• issues/133196

• DRA Health API Enhancement: There is a proposal to add a detailed, human-readable message field to the Pod Resource Health Status in the DRA Health gRPC API. This would provide specific context about device health, improving troubleshooting and user experience beyond the existing HealthStatus enum.
• issues/133202

• DRA End-to-End Test Flakiness: The "supports reusing resources" DRA end-to-end test flakes due to timeouts caused by scheduling many pods after removing concurrent user limits on claims. This leads to unpredictable performance and suggests the test may need disabling or modification.
• issues/133209

• Probe Timeout Override Failure: Kubernetes end-to-end tests fail because the probing container does not correctly override timeoutGracePeriodSeconds when LivenessProbe or StartupProbe fields are set. This results in unexpected container restart counts during node conformance testing.
• issues/133216

• DRA Resource Health Test Failures: Persistent failures occur in DRA Resource Health status end-to-end node tests, where device health changes are not reflected correctly and tests time out waiting for "Healthy" status. This indicates problems with the ResourceHealthStatus feature gate handling in the test environment.
• issues/133219

• Windows CI DRA Flaky Test: A recurring flaky test in Windows CI related to DRA causes kubelet to fail resource allocation due to a CEL selector runtime error "no such key: healthy." This intermittently blocks pull requests on Windows nodes.
• issues/133223

• Go Language Breaking Change Impact: A recent Go language commit introduced a breaking change causing Kubernetes unit test failures due to a panic from an invalid gzip checksum in protobuf handling. This issue appears linked to new CPU instruction sets and cannot be easily reproduced locally.
• issues/133224

• Downward API Pod-Level Resource Test Failure: Downward API tests for pod-level resources fail to provide correct default CPU and memory limits, causing mismatches in expected and actual MEMORY_LIMIT values after merging PR #132605.
• issues/133232

• Kube-apiserver High Memory Usage: The kube-apiserver consumes an unusually high amount of memory (20GB) which significantly drops after container restart. This raises concerns about whether it is failing to release memory timely under heavy cluster load.
• issues/133233
