We consider active issues to be issues that that have been commented on most frequently within the last week. Bot comments are omitted.
-
Does it make sense to use ServiceAccounts for custom resources?: This issue discusses the potential use of ServiceAccounts for custom resources in the context of CNCF Flux, specifically regarding the introduction of
spec.serviceAccountNamefields to issue JWTs through the TokenRequest API and exchange them for Access Tokens in cloud providers' Security Token Services. The author seeks clarification on whether this approach aligns with Kubernetes' intended use of ServiceAccounts, as they are traditionally associated with Pods, and whether this method could be considered an abuse of the system.- The comments explore the feasibility and implications of using ServiceAccounts for custom resources, with discussions on security concerns, potential attack vectors, and the alignment with Kubernetes' architecture. Participants provide insights into alternative methods, such as binding tokens to Secret objects, and discuss the broader ecosystem's direction regarding workload identity. The conversation also touches on the potential for Kubernetes to support more granular identity management for controllers and the need for cloud providers to accommodate such use cases without breaking existing integrations.

-
[Flaking Test] [sig-api-machinery] ResourceQuota should create a ResourceQuota and capture the life of a ResourceClaim [FeatureGate:DynamicResourceAllocation]: This issue is about a flaking test in the Kubernetes project, specifically within the sig-api-machinery group, where the ResourceQuota test is failing to create a ResourceQuota and capture the life of a ResourceClaim due to a context deadline exceeded error. The problem has been occurring since May 12th, and it appears to be related to how the resource quota controller reconciles, rather than the Dynamic Resource Allocation logic itself.
- The comments discuss the rarity and difficulty in reproducing the flake, with attempts to trigger it locally and in CI without success. It is noted that the flake is not specific to ResourceClaim, though it occurs more frequently with it. The test has been identified as the flakiest in the beta job, and there are plans to merge an enhanced test to gather more information. Despite active monitoring, the flake has not reappeared recently.
- Number of comments this week: 7
-
apimachinery/pkg/util/errors: deprecate MessageCountMap: This issue proposes the deprecation of the
MessageCountMapandCreateAggregateFromMessageCountMapfunctions from thek8s.io/apimachinery/pkg/util/errorspackage, as they are no longer used in the Kubernetes codebase and the functionality is now covered by theerrors.Joinfunction available since Go 1.20. The deprecation is suggested to encourage developers to transition away from the outdated package and adopt the newer, more efficient error handling methods.- The comments discuss assigning the issue to a contributor, with one person expressing interest in taking it up if no one else is working on it. There is a concern about whether the functions can be easily replaced by
errors.Joinand whether any subprojects are still using these methods. A search indicates that the functions are primarily used in vendor directories. - Number of comments this week: 6

-
kubelet device manager provides some useless hints: This issue highlights a problem with the kubelet device manager in Kubernetes, where it provides an excessive number of hints for GPU allocation, far exceeding the number of available GPUs, which significantly reduces the efficiency of computing the best hint. The user expected the device manager to generate hints that match the requested number of GPUs, as the current behavior results in a substantial decrease in performance, particularly when creating a 1-GPU pod on a node with multiple NUMA nodes.
- The comments discuss the inefficiency caused by the device manager generating excessive hints, leading to a lengthy pod admission time. The issue is acknowledged as a known scalability problem with the topology manager, and there is a suggestion to open a more generic issue to address the slow admission time, as the current behavior is considered expected but undesirable.
- Number of comments this week: 5
-
goroutines may stuck in method (*cacheWatcher).processInterval because of watch clients do not deal with watch event: This issue is about a potential bug in a Kubernetes cluster where goroutines may become stuck in the
(*cacheWatcher).processIntervalmethod because watch clients do not handle watch events properly. The problem arises when a test client in the cluster watches cluster resources but does not process the events, leading to concerns about whether these events can be garbage collected if the watch goroutine does not exit.- The comments discuss assigning the issue to a specific person and accepting it for triage. A suggestion is made to either kick watchers referencing outdated events or impose a limit, as the current behavior may prevent events from being garbage collected.
- 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.
- apimachinery resource.Quantity primitive values should be public for recursive hashing: This issue addresses the need for the primitive values within the
apimachinery resource.Quantitystruct to be made public to facilitate recursive hashing, which is currently hindered by their private status. The lack of public access to these values complicates the process of detecting changes in Custom Resource Definitions (CRDs) for projects likekubernetes-sigs/karpenter, which rely on hash comparisons to identify specification drifts, impacting resource allocation and necessitating cumbersome workarounds. - APF borrowing by exempt does not match KEP: This issue highlights a discrepancy between the Kubernetes Enhancement Proposal (KEP) and its implementation regarding how the exempt priority level borrows from other levels in the system. Specifically, the KEP outlines a distinct formula for calculating the minimum concurrency limit for exempt levels, which is not reflected in the current implementation, leading to potential inconsistencies in resource allocation.
- apimachinery's unstructured converter panics if the destination struct contains private fields: This issue describes a problem with the
DefaultUnstructuredConverterin the Kubernetesapimachinerypackage, where it panics when attempting to convert an unstructured object to a structured object if the destination struct contains private fields. The panic occurs because the converter tries to set values on non-exported fields, which is not allowed in Go, and the user expects the converter to ignore these private fields instead of causing a panic. - Jsonpath impl does not support left match regex: This issue is about the lack of support for the
=~operator in jsonpath filter expressions within a GitHub project, which prevents users from performing left match regex operations. The addition of this feature would allow users to efficiently locate resources by matching patterns, such as identifying items whose descriptions start with a specific string, thereby simplifying resource management in systems with numerous resources. 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: 29
Summarized Issues:
- Goroutine Stuck in processInterval: This issue describes a problem in a Kubernetes cluster where goroutines may become stuck in the
(*cacheWatcher).processIntervalmethod. This occurs because watch clients do not handle watch events, potentially preventing events from being garbage collected and causing the watch goroutine to not exit.
- Integration with Go 1.20's errors.Join: This issue involves updating the
k8s.io/apimachinery/pkg/util/errorspackage to integrate with Go 1.20'serrors.Join. It includes implementing theUnwrap() []errormethod for theaggregatetype and deprecating the currentErrors() []errormethod to align with standard library practices.
- Documentation for x-kubernetes Extensions: This issue is about adding documentation for the
x-kubernetes-list-type,x-kubernetes-map-key, andx-kubernetes-unionsfields. Theapi/openapi-spec/README.mdfile currently lacks information on these specificx-kubernetesextensions.
- Device Allocator Performance: This issue addresses the slow performance of the device allocator in Kubernetes. It struggles to efficiently find a suitable set of devices to satisfy
ResourceClaims, leading to significant delays and necessitating discussions on potential improvements and performance optimizations.
- Metric Discrepancy in kubelet_pod_start_sli_duration_seconds: This issue highlights a discrepancy between the expected behavior and the actual implementation of the
kubelet_pod_start_sli_duration_secondsmetric. The metric is supposed to exclude the runtime of init containers, but testing and code inspection suggest that this exclusion is not occurring.
- ServiceAccounts for Custom Resources in CNCF Flux: This issue discusses whether it is appropriate to use Kubernetes ServiceAccounts for custom resources in the context of CNCF Flux. It raises concerns about potential misuse, ecosystem compatibility, and future constraints related to Kubernetes' direction towards pod-bound workload identity.
- Failing Tests and Reconciliation Issues: This issue involves a failing test in the Kubernetes project, specifically the
Test_StorageVersionUpdatedWithAllEncodingVersionsEqualOnLeaseDeletion. It is encountering unexpected storage version objects and common encoding versions, leading to a runtime error due to an index out of range.
- Discrepancy in topologySpreadConstraints Handling: This issue highlights a discrepancy in the Kubernetes API Server's handling of
topologySpreadConstraintsbetweenStatefulSetsandDeployments. A missingwhenUnsatisfiablefield causesDeploymentsto be correctly rejected due to validation errors, whileStatefulSetsare incorrectly accepted but fail to schedule pods.
- kube-proxy Traffic Dropping in nftables Mode: This issue describes a problem where using kube-proxy in nftables mode with a LoadBalancer Service set to
externalTrafficPolicy:Localresults in traffic being dropped to the external IP. This prevents pods on the host from sending traffic to the LoadBalancer's external IP.
- CPU Manager Test Failures: This issue pertains to a failing test in the Kubernetes project related to the CPU Manager. Non-guaranteed pods are not able to access all online CPUs as expected due to a missing file or directory error, highlighting the need for test adjustments.
- Kubelet Reconnection to DRA Plugin: This issue involves measuring the reconnection time of the kubelet to the Device Resource Allocation (DRA) plugin during kubelet restarts and plugin crashes. It includes updating the documentation by consolidating notes and discussions from various documents and meetings.
- Network Connectivity Issues During StatefulSet Upgrades: This issue describes a problem during large-scale Kubernetes cluster upgrades where the garbage collector deletes old pods that are terminating during a StatefulSet rolling upgrade. This leads to network connectivity issues for new pods because the old pod's delayed network teardown inadvertently removes the new pod's network interface.
- Pod Stuck in ContainerCreating Status: This issue involves a Kubernetes pod stuck in the "ContainerCreating" status due to a kubelet error where the connection to the kubelet.sock is refused. It likely follows a firmware update on RHEL 8 and lacks clear reproduction steps or conditions for further diagnosis.
- cachingObject Skipping defaultOnRead Method: This issue describes a problem where the
cachingObjectskips thedefaultOnReadmethod when pushing events. This leads to a scenario where Service objects upgraded from a version older than 1.20 do not include theIPFamiliesfield in their events.
- kube-log-runner Log Splitting Issue: This issue addresses the problem of kube-log-runner splitting log streams without respecting log record boundaries when using log rotation. It proposes the use of Unix Domain sequential packet sockets to ensure complete log records are maintained in each log file.
- Standardizing Metric Reference Resources: This issue addresses the need to standardize the format of metric reference resources in a Kubernetes project. It proposes adopting a consistent labeling approach to reduce confusion, improve filtering, and facilitate metric aggregation.
- Migrating DeepCopy Functions to deepcopy-gen: This issue involves migrating manually written DeepCopy functions in the Kubernetes scheduler implementation to an automated solution using
deepcopy-gen. This is to improve maintainability and prevent issues like those referenced in a previous pull request.
- Resource Usage Calculation for DRAPrioritizedList: This issue addresses the need to update the resource usage calculation to support the DRAPrioritizedList feature in Kubernetes. Currently, users can bypass ResourceQuota checks when this feature is enabled, and this update is necessary before the feature can be promoted to beta.
- mTLS Authentication for ConversionWebhook: This issue is about adding an option for mutual TLS (mTLS) authentication for the ConversionWebhook in Kubernetes. The current setup causes TLS handshake errors when the kube-apiserver does not present a client certificate.
- Field-Level Deprecation Warnings in CRD Generation: This issue discusses the need for implementing field-level deprecation warnings in Custom Resource Definition (CRD) generation within the Kubernetes ecosystem. It proposes a mechanism to make deprecated fields more visible to end users by providing actionable warnings at runtime.
- ReplicationController Reconciliation with DeploymentReplicaSetTerminatingReplicas: This issue involves a problem where a ReplicationController cannot fully reconcile with the DeploymentReplicaSetTerminatingReplicas feature gate enabled. It results in extra synchronization logs in the Kubernetes Controller Manager (KCM).
- Validation of createNodeOp Function: This issue concerns the validation of the
createNodeOpfunction in the Kubernetes scheduler. It specifically addresses whether an error should be raised when the number of nodes is set to zero.
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: 12
Summarized Issues:
- Kubernetes CronJobs and Kubelet Cleanup Issues: The Kubernetes cluster experiences issues with a high number of CronJobs where the kubelet fails to clean up exited containers. This leads to IP address management congestion and eventual failure due to exceeding gRPC message size limits, despite configuration adjustments.
- Kubernetes Build and Certificate Verification Errors: A failure occurs in building the Busybox image for Windows due to a TLS certificate verification error. The error arises when attempting to download a curl binary from an unofficial source, suggesting a need to switch to a more reliable source or modify the build process.
- Kubelet Pod Removal and Cache Operation Errors: The Kubernetes kubelet faces issues where the
NodeUnprepareResourcesfunction does not block pod removal with a zeroterminationGracePeriod. This results in a failure to set up a container due to a locked cache operation error, suspected to be caused by a race condition.
- Kubernetes Scheduler Test Flakes: The Kubernetes scheduler integration test experiences a flake where a pod with node affinity is scheduled on the wrong node. This unexpected behavior is observed in the TestNodeAffinityScoring test, leading to incorrect test results.
- Kubernetes Scheduler Preemption Test Issues: In the Kubernetes scheduler preemption test, low-priority pods with finalizers are expected to remain undeleted until high-priority pods are scheduled. However, a synthetic delete event violates this assumption, causing premature scheduling of high-priority pods.
- Kubernetes Connectivity Test Failures: The "Connectivity Pod Lifecycle" test in Kubernetes fails to achieve zero downtime during a Blue-Green deployment due to a connectivity error. The system incorrectly connects to the "blue-pod" instead of the "green-pod," causing the test to fail.
- Persistent Volume State Update Issues: A potential problem arises when a Persistent Volume (PV) is updated to the "Released" state while still being detached. This can lead to a failed DeleteVolume operation and misleading error feedback due to the volume's attached state.
- Kubernetes API Server Memory Regression: A regression in memory usage for Kubernetes' API server is observed, where a performance improvement inadvertently increases memory consumption from 3 GB to 30 GB. This is potentially due to changes in JSON encoding for audit logs.
- Kubernetes Service Controller Reconciliation Failures: The Kubernetes service controller fails to retry service reconciliation when the UpdateLoadBalancer function returns an error. The error is overwritten by a subsequent successful call to GetLoadBalancer, resulting in incomplete backend node updates.
- Kubernetes Secrets Security Concerns: Concerns are raised about the security of Kubernetes secrets, criticizing the use of base64 encoding for passwords. The suggestion is to adopt Argon2 hashing to enhance security and prevent unauthorized access to original secret values.
- ResourceSlice CRD Field Selector Feature: A request is made to add
spec.nodeNameto the selectable fields of theResourceSliceCRD in Kubernetes. This would allow efficient server-side execution of field selector queries, but it was later discovered that this feature was already implemented.
- Kubernetes Descheduler Eviction Issues: The descheduler version 0.30 attempts to evict pods even when no suitable nodes are available for relocation. This occurs despite configuration settings intended to prevent such actions when no fit nodes are present.

This change aims to eliminate unnecessary log noise and potential confusion caused by the hardcoded version check.
- Dynamic Resource Allocation Plugin Registration: An end-to-end node test has been introduced to verify that the kubelet plugin manager correctly retries the plugin registration process after a failed
GetInfocall. This ensures that the plugin is successfully registered once theGetInfocall succeeds, improving the robustness of the Dynamic Resource Allocation (DRA) plugin registration process in failure scenarios.
- Pod Admission and Resize Logic Refactor: The Kubernetes codebase has been refactored by moving the pod admission and resize logic into the allocation manager. This effort is part of a cleanup process to untangle dependencies without altering the existing business logic, in preparation for future changes.
- Horizontal Pod Autoscaler Enhancement: A new feature allows the Horizontal Pod Autoscaler (HPA) to scale based on the current number of replicas when no matched Pods are ready. This addresses issue #130130 in the Kubernetes project.
- ReplicationController Bug Fix: A bug has been addressed by disabling the reconciliation of terminatingReplicas in the ReplicationController when the DeploymentReplicaSetTerminatingReplicas feature gate is enabled. This fixes issue #131821 in the Kubernetes project.
- ResourceQuota Test Flake Debugging: A pull request focuses on debugging a test flake related to the ResourceQuota in Kubernetes, where the test sometimes fails due to discrepancies in expected versus actual resource counts. Changes include making assertions more verbose to aid in understanding and resolving the issue, although it is not intended to be merged.
