I. News

1.1 Recent Version Releases:

The current version of this repository is v1.32.3

1.2 Version Information:

The Kubernetes 1.32 release, announced on March 11, 2025, introduces several key updates and improvements detailed in the official CHANGELOG, with additional binary downloads available. This version continues to enhance Kubernetes' functionality and stability, reflecting ongoing development trends in the platform.

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. [KIND/BUG] [SIG/NETWORK] [NEEDS-TRIAGE] [AREA/IPVS] The externalTrafficPolicy configuration is invalid.: This issue reports that when using Kubernetes with externalTrafficPolicy set to Local, traffic sent to a node that does not have the pod deployed is unexpectedly accepted instead of being rejected as documented. The user is specifically encountering this behavior on a cluster using IPVS mode and Flannel CNI, and suspects that CNI or cloud provider masquerading rules may be interfering with the expected traffic handling.

   • Commenters confirmed the issue can be reproduced under certain conditions and noted that IPVS proxier is deprecated and unmaintained, recommending switching to nftables; they also discussed how CNI plugins and cloud provider iptables rules can alter expected behavior, and that the external load balancer should ideally not send traffic to nodes without endpoints, though this can happen during reconfiguration.
   • Number of comments this week: 18

2. [KIND/BUG] [NEEDS-SIG] [NEEDS-TRIAGE] [SIG/NODE] [KIND/REGRESSION] Container fail to create when env var contains $ followed by non-ASCII character (invalid UTF-8 gRPC error): This issue describes a regression introduced in Kubernetes v1.34.x where containers fail to create on nodes running v1.34.2 if an environment variable contains a dollar sign followed immediately by a non-ASCII character, resulting in a gRPC marshaling error due to invalid UTF-8. The problem did not occur in v1.33.5 and was traced to a change in serialization from gogo-protobuf to standard proto serialization, which enforces stricter UTF-8 validation on environment variable strings passed to the container runtime interface.

   • The comments detail investigation steps including bisecting the codebase to identify the commit that introduced the regression, adding unit tests to reproduce the invalid UTF-8 serialization error, and confirming that a recent pull request fixing this issue should be backported to affected Kubernetes versions to resolve the problem.
   • Number of comments this week: 10

3. [KIND/BUG] [NEEDS-TRIAGE] [WG/DEVICE-MANAGEMENT] DRA: Non-pod references in ReservedFor prevents removal of pod references: This issue describes a problem where the status.reservedFor field in the ResourceClaim resource can contain non-pod references that prevent the resourceclaim controller from removing pod references when pods terminate, leading to stale pod references remaining. The expected behavior is that pod references should be removed upon pod termination while non-pod references remain, but currently, the presence of any non-pod reference blocks this cleanup, causing resource claims to stay allocated incorrectly.

   • The comments include multiple users expressing interest in addressing the issue, discussion of the controller’s current behavior and potential code changes, and agreement that cleaning up pod references upon pod termination is a reasonable interim solution; a PR has been created and is under review with contributors coordinating on next steps.
   • Number of comments this week: 9

4. [KIND/BUG] [NEEDS-SIG] [NEEDS-TRIAGE] [SIG/NETWORK] kube-apiserver fails to start because start-service-ip-repair-controllers PostStartHook fails: This issue describes a problem where the kube-apiserver fails to start during an upgrade from Kubernetes v1.32 to v1.33 because the start-service-ip-repair-controllers PostStartHook encounters errors when the ipaddresses.networking.k8s.io API is not ready, likely due to a race condition involving the MultiCIDRServiceAllocator feature being enabled by default. The root cause is that the repair controller attempts to create missing IPAddress objects before the Namespace informer and admission webhooks are fully synced, causing admission errors and preventing the API server from becoming ready, especially in clusters with many namespaces.

   • The comments discuss analysis of the root cause, confirming that the admission webhook depends on the Namespace informer being synced, and propose a fix to wait for the Namespace informer before running the repair logic. A patch is developed to add this wait and retain retry logic, with further suggestions to decouple the PostStartHook from blocking on the repair operation. The discussion also clarifies that the error is due to admission webhooks not being ready, affecting IPAddress and other resource creations, and the fix aims to improve startup reliability in large clusters.
   • Number of comments this week: 8

5. [KIND/BUG] [NEEDS-SIG] [NEEDS-TRIAGE] fake.NewClientset fails to perform Apply/Patch for custom resources (rather than deprecated NewSimpleClientset works) in tests: This issue describes a problem where the fake.NewClientset generated client fails to perform the Apply method for custom Kubernetes resources in tests after migrating to Kubernetes 1.35, while the deprecated fake.NewSimpleClientset continues to work as expected. The failure appears related to the managed fields tracking during server-side apply operations for custom resources, causing errors that do not occur with default Kubernetes resources or in actual API servers.

   • The comments clarify that the root cause is the lack of generated OpenAPI needed for server-side apply in the fake client, not the Apply method itself; users confirm the issue only arises in tests using fake.NewClientset and suggest keeping NewSimpleClientset available to avoid breaking test setups, with references to related pull requests and potential duplicates.
   • Number of comments this week: 8

2.2 Top 5 Stale Issues:

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: 35

Summarized Issues:

• Kube-apiserver startup failure due to informer sync race condition: The kube-apiserver fails to start during an upgrade from v1.32 to v1.33 because the start-service-ip-repair-controllers PostStartHook encounters a race condition where the IPAddresses API is not ready. This is caused by required informers, especially the Namespace informer, not being synced, leading to admission webhook errors and preventing readiness.
• issues/136288

• Permission denied errors during code generation: After upgrading Kubernetes dependencies to version 0.35.0, code generation fails with permission denied errors because the generator tries to write generated files into read-only Go module cache directories. This prevents successful code generation and blocks development workflows.
• issues/136295

• Graduation of various Kubernetes metrics to BETA: Multiple issues track the promotion of different Kubernetes metrics from alpha or experimental states to BETA status, covering apiserver, etcd, network endpoint slice, job_controller, resourceclaim, storage, scheduler, component-base, and serviceaccount metrics. These efforts focus on improving observability and instrumentation by completing implementation and integration tasks for each metric set.
• issues/136304, issues/136305, issues/136306, issues/136307, issues/136308, issues/136310, issues/136311, issues/136312, issues/136313

• Cloud-provider service controller reconciliation issue: The cloud-provider service controller does not trigger reconciliation when a LoadBalancer Service's status is cleared by external controllers like GitOps tools. This causes the Service to remain in a pending state indefinitely despite the cloud load balancer functioning correctly.
• issues/136316

• Container creation failure due to environment variable encoding regression: In Kubernetes v1.34.2, containers fail to create on upgraded nodes if an environment variable contains a dollar sign followed immediately by a non-ASCII character. This causes a gRPC marshaling error due to invalid UTF-8, whereas the same configuration works on v1.33.5 nodes.
• issues/136323

• Immutable selector.matchLabels field in Deployments causes update difficulties: The immutable selector.matchLabels field in Kubernetes Deployments creates user difficulties and risks when updating label values and managing parent/child resource relationships. This immutability complicates resource updates and may lead to unexpected behavior.
• issues/136324

• Fake clientset Apply/Patch failures for custom resources in testing: The fake.NewClientset in Kubernetes 1.35 fails to perform Apply or Patch methods for custom resources during testing, causing errors related to managed field tracking and schema conversion. The deprecated fake.NewSimpleClientset continues to work as expected, highlighting regression in the newer clientset.
• issues/136327

• Containerd serial test failures on reboot due to user namespace mismatch: Containerd serial tests fail on reboot primarily on Container-Optimized OS (COS) because kubelet cannot restart due to a mismatch in user namespace lengths when reconstructing pod mappings. This issue causes all related tests to fail since mid-January 2026.
• issues/136331

• Kubernetes emits zero-value Kubelet PSI metrics when PSI is disabled: Kubernetes 1.34 reports zero-value Pressure Stall Information (PSI) metrics even when the underlying OS does not enable PSI. This causes confusion by visually implying PSI is active in monitoring tools like Grafana despite being inactive.
• issues/136333

• ExternalTrafficPolicy=Local NodePort service accepts traffic on nodes without local pods: The externalTrafficPolicy set to Local in a NodePort service does not reject traffic on nodes without local pods as expected. This likely results from interactions with IPVS mode and CNI plugins such as Flannel, causing unexpected traffic acceptance.
• issues/136338

• Duplicate container ports with different protocols cause port removal on update: Adding duplicate container ports with different protocols (TCP and UDP) to a Deployment results in one port being removed after updating the pod spec. This occurs because the merge key only considers the containerPort number, ignoring protocol differences.
• issues/136340

• Flaky test failures in kubelet volumemanager and GPUDevicePlugin: Several tests intermittently fail, including the volumemanager's TestWaitForAllPodsUnmount, GPUDevicePlugin's GPU detection tests, and scheduler plugin integration tests. These flakes affect multiple CI jobs and cause pod phase mismatches and error events.
• issues/136376, issues/136378, issues/136382

• ClusterLoaderV2 access-tokens test exceeds latency thresholds: The ClusterLoaderV2 access-tokens overall test consistently reports API responsiveness exceeding the expected 30-second 99th percentile latency threshold across multiple runs since January 7, 2026. This indicates performance regressions in API responsiveness.
• issues/136384

• ResourceClaim status.reservedFor does not remove pod references on pod termination: The status.reservedFor field in ResourceClaim fails to remove pod references when a pod terminates if non-pod references are also present. This causes pod references to persist incorrectly, potentially leading to resource reservation inconsistencies.
• issues/136406

• Replacement of deprecated google/btree dependency with k8s/utils btree: The deprecated and archived google/btree dependency is being replaced with the implemented btree in k8s/utils across the codebase, focusing initially on the single instance in the apiserver. This update modernizes dependencies and reduces reliance on archived projects.
• issues/136415

• Post-quantum cryptography readiness research and recommendations: Research-based observations and recommendations aim to improve Kubernetes' readiness for post-quantum cryptography transitions by enhancing visibility, governance, and migration planning aligned with NIST guidance. This prepares Kubernetes for future cryptographic standards.
• issues/136417

• Proposal to export validateAffinity() for external reuse: The private validateAffinity() function is proposed to be exported as ValidateAffinity() to allow external projects to reuse Kubernetes' internal affinity validation logic. This reduces code duplication, maintenance burden, and ensures consistent validation behavior across client and server.
• issues/136422

• NewClientset options ignored causing TypeMeta equality check failures: The NewClientset function in client-go testing ignores options passed to create, patch, or delete functions, causing discrepancies in TypeMeta handling and failures in equality checks when switching from NewSimpleClientset. This leads to test failures and inconsistent behavior.
• issues/136427

• NUMANodeAffinity hint in topology manager does not prefer majority device NUMA node: The best-effort topology manager's NUMANodeAffinity hint fails to properly account for device distribution across NUMA nodes, resulting in suboptimal scheduling that does not prefer the NUMA node containing the majority of requested GPUs. This affects pod placement on multi-NUMA node servers.
• issues/136431

• Audit log rotation not disabled when --audit-log-maxsize=0 is set: Setting --audit-log-maxsize to 0 in kube-apiserver does not disable audit log rotation as documented; instead, logs rotate at 100MB due to the lumberjack library defaulting zero to 100MB. This causes unexpected log rotation and potential disk exhaustion.
• issues/136448

• Lack of basic tests for several kubectl resource describers: Several kubectl resource describers lack basic tests to verify output formatting and prevent regressions, including ReplicaSet, CronJob, Role, ClusterRole, RoleBinding, ClusterRoleBinding, and CertificateSigningRequest. Adding tests improves reliability and maintainability.
• issues/136460

• Plugin manager registers plugins despite failure to add to Actual State of the World: The plugin manager continues to register a plugin even after failing to add it to the Actual State of the World (ASW), which should instead cause the registration to fail. This leads to inconsistent plugin states and potential errors.
• issues/136462

• Kubelet static pod initialization misses API server defaulting and strategy methods: Kubelet's static pod initialization does not fully replicate API server defaulting and strategy methods, missing fields set by podStrategy#PrepareForCreate. This may cause inconsistencies in pod handling between static pods and API server-created pods.
• issues/136471

• Panic in kube-controller-manager due to nil pointer in ValidatingAdmissionPolicy: A nil pointer dereference panic occurs in kube-controller-manager when using a ValidatingAdmissionPolicy, likely caused by common.SchemaDeclType() returning nil without proper checks. This leads to controller crashes and instability.
• issues/136472

• Proposal to extend DRA performance tests to include implicit resources: Current DRA performance tests cover only explicit extended resources; the proposal is to extend testing to implicit resources to measure and compare performance results for both types. This would provide more comprehensive performance insights.
• issues/136473

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: 10

Summarized Issues:

• Service Output and Debugging Issues: The appProtocol field, available since Kubernetes v1.20, is not shown in kubectl describe service output, complicating debugging for Service Mesh or Gateway API configurations. Adding this field to the port section would improve consistency and usability for users.
• issues/135741

• ResourceClaim Handling Errors: The kubelet fails to correctly handle multiple ResourceClaims when a second pod references both a previously prepared claim and an additional one, causing internal errors during container creation despite successful scheduling. This issue affects pod lifecycle management and resource allocation reliability.
• issues/135901

• Windows kube-proxy DualStack Load Balancer Bugs: Services with ipFamilyPolicy: RequireDualStack on Windows kube-proxy intermittently program incorrect load balancers, mismatching IPv4 and IPv6 endpoints with virtual IPs. This results in traffic blackholing, connection failures, and inconsistent load balancer flags, especially during endpoint or service updates and rapid pod churn.
• issues/136240

• End-to-End SSH Connectivity Test Failures: The SSH connectivity test to all nodes consistently fails due to errors indicating a missing port in the address when dialing a non-existent host during pull-kubernetes-e2e-gce test runs. This failure impacts the reliability of node connectivity validation in CI.
• issues/136260

• Pod Scheduling Feedback Enhancements: There is a request to add a Pod condition in kube-scheduler that clearly indicates when a Pod fails the PreEnqueue stage, providing reasons, messages, and timestamps. This would help users understand why Pods are not considered for scheduling, improving transparency and debugging.
• issues/136335

• Post-Quantum Cryptography Readiness: Research highlights Kubernetes' lack of centralized cryptographic inventory, migration frameworks, and governance visibility for post-quantum cryptography transitions. Early awareness and community discussion are advocated to ensure future-proof security aligned with NIST guidance.
• issues/136346

• CI Build Failures Due to Missing Files: A post-merge continuous integration job fails because a required Python script file is missing during the build process, causing a non-zero exit status. This interrupts the automated build pipeline and requires fixing missing dependencies.
• issues/136347

• Image Build Failures from Missing Debian Stretch Files: The image build process fails due to missing Release files and 404 errors when fetching Debian Stretch package repositories during apt-get update and install steps. This breaks the build and necessitates repository or base image updates.
• issues/136350

• Outdated Debian Jessie Base Image Causing Build Failures: Using the deprecated Debian Jessie base image in the Dockerfile leads to 404 errors during package updates because its repositories have been moved or removed. Updating to a supported base image or repository configuration is required to fix the build.
• issues/136357

• Spam Issue Report: An issue titled only "U" with no description was flagged as likely spam and recommended for closure due to lack of information. This helps maintain issue tracker quality by removing non-informative reports.
• issues/136418
