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. Add new imagePullPolicy mode IfNewerNotPresent, that pulls image if image ID (ref/digest) on remote is not matching.: This issue proposes adding a new imagePullPolicy mode called IfNewerNotPresent that pulls a container image only if the image ID (reference or digest) on the remote registry does not match the local image, addressing scenarios where image tags are reused with backported fixes without changing the tag. This mode aims to combine the speed benefits of IfNotPresent with an integrity check against the remote registry, reducing unnecessary pulls and network load while ensuring pods do not run outdated or faulty images when tags are mutated.

   • The discussion centers on clarifying differences between existing policies IfNotPresent and Always, with contributors explaining that Always always checks the remote registry but reuses cached layers, while IfNotPresent skips remote checks if the image exists locally. The proposer argues that Always can cause performance and registry load issues at scale and does not handle registry outages gracefully, motivating the need for a middle ground policy. Others caution that mutating tags is discouraged best practice and that the proposal may introduce complexity and security concerns. Testing results shared show IfNewerNotPresent can reduce pull times by only verifying image digests remotely. The conversation also touches on naming semantics and the importance of handling network failures without blocking pod startups.
   • Number of comments this week: 18

2. [node] Missing conformance endpoints for podexec / portforward using POST (and namespaced) (2 operations): This issue addresses the absence of conformance test coverage for two specific POST operations related to pod exec and port forwarding in the Kubernetes API, which are connectCoreV1PostNamespacedPodExec and connectCoreV1PostNamespacedPodPortforward. The discussion highlights that these endpoints use the deprecated SPDY protocol, which has been largely replaced by websockets (using GET requests) in newer versions of kubectl, leading to these POST endpoints being untested and proposed to be marked as ineligible for conformance.

   • The comments clarify that the missing coverage is due to a protocol transition from SPDY POST to websocket GET, with SPDY being unreliable and deprecated but still in use internally; contributors agree to mark the SPDY POST endpoints as ineligible for conformance tests while continuing to test websocket GET endpoints, and they discuss the implications and timeline for deprecating SPDY without immediate removal.
   • Number of comments this week: 10

3. Pick predicatable device class when multiple device classes use the same extended resource name: This issue addresses the need to implement a predictable selection mechanism for device classes when multiple device classes share the same extended resource name, replacing the current random selection approach used in Alpha with a deterministic method as outlined in the Kubernetes Enhancement Proposal (KEP) for Beta. The goal is to improve user experience by ensuring that the device class chosen at scheduling time is either the one created later or, if created simultaneously, the one with the lexicographically first name, while also discussing the possibility of raising errors or adding priority fields for more granular control.

   • The comments discuss clarifications about the referenced KEP and its guidance, debate the merits of deterministic selection versus raising scheduling errors or random selection, and consider the lack of clear use cases for multiple device classes sharing the same resource name; ultimately, the consensus leans toward implementing deterministic selection for better UX while deferring more complex features like priority fields until a clear need arises.
   • Number of comments this week: 10

4. The pod in the host network will have the contents of the host's hosts file.: This issue addresses the problem where a pod running in the host network namespace inherits the host's /etc/hosts file contents, which can cause incorrect IP resolution due to conflicting domain entries. The user requests an option to control whether the pod should include the host's hosts file data, as this behavior is not always desirable and leads to resolution conflicts.

   • The discussion clarifies that pods in the host network share the host's network stack, so they naturally use the host's /etc/hosts file, and suggestions include using Pod.DNSConfig or mounting a custom /etc/hosts file to override defaults. Commenters ask for more details and reproduction steps to better understand the issue, while also providing links to relevant container runtime code and Kubernetes DNS policy options.
   • Number of comments this week: 8

5. ResourceQuota not updating due to the quota monitor not synced: This issue describes a problem where the Kubernetes ResourceQuota controller fails to update resource quotas because it gets stuck waiting for the quota monitor to sync, particularly after restarting kube-controller-manager instances. The root cause appears to be that newly introduced aggregated API resources from the spdx.softwarecomposition.kubescape.io/v1beta1 group do not properly support List/Watch operations with PartialObjectMetadata, causing the controller to block and preventing resource quota updates.

   • The comments confirm that the issue stems from incompatibilities in the aggregated API server’s implementation of the storage interface, which affects watch functionality and blocks the ResourceQuota controller. It was noted that the problem is fixed in a newer version of the kubescape storage release, and there is consensus that the ResourceQuota controller should be enhanced to tolerate such CRD resource failures without blocking, similar to improvements made in the garbage collector.
   • 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. Zone-aware down scaling behavior: This issue describes a problem with the zone-aware downscaling behavior of Kubernetes Horizontal Pod Autoscaler (HPA) workloads, where the scale-in process leads to an uneven distribution of pods across availability zones despite using topology spread constraints with maxSkew: 1. Specifically, during scale-in events, one zone ends up with significantly fewer pods than others, causing high CPU usage on the remaining pod in that zone and violating the expected balanced pod distribution 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 notably with protobuf-generated gRPC structs that include private fields for internal state, causing the conversion process to fail even when only public fields are present in the unstructured data.
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 proper recursive conversion calls. 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 conversion functions.
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 multiple errors 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: 29

Summarized Issues:

• Pod Networking and Host File Inheritance: Pods running in the host network namespace automatically include the host's /etc/hosts file contents, which can cause incorrect domain name resolution due to conflicting IP addresses. This issue requests an option to control whether the pod inherits the host's hosts file to avoid such conflicts.
• issues/133679

• Image Pull Policy Enhancement: A new imagePullPolicy mode called IfNewerNotPresent is proposed to pull container images only if the remote image ID differs from the locally cached one. This approach aims to combine the efficiency of IfNotPresent with an integrity check to avoid running outdated images while reducing unnecessary network traffic compared to the Always policy.
• issues/133680

• API Server and Etcd Call Optimization: The Kubernetes API server currently makes two separate Etcd calls—a Get after a failed OptimisticPut—which could be optimized by setting GetOnFailure = true in PutOptions. This change would reduce redundant Etcd API usage by receiving the current key value in a single gRPC call.
• issues/133683

• Code Refactoring for Pod QOS Computation: The ComputePodQOS function in the kubelet is proposed to be refactored by extracting resource-collection logic into a helper function. This would improve code readability and testability without changing the function's behavior.
• issues/133685

• Conformance Test Coverage for Deprecated Endpoints: There is a lack of conformance test coverage for deprecated SPDY POST endpoints in Kubernetes, raising the question of whether to mark these operations as ineligible for conformance due to the transition to websocket GET methods. This highlights the need to address testing gaps for legacy API endpoints.
• issues/133689

• Promotion of Untested Conformance Endpoints: Kubernetes version 1.34.0 includes 34 conformance endpoints that currently lack associated tests, emphasizing the need to implement comprehensive testing for these CRUD operations to ensure conformance compliance.
• issues/133691

• Deterministic Device Class Selection: A deterministic method is requested for selecting a device class when multiple classes share the same extended resource name. Following KEP guidance, the selection should avoid randomness by choosing the device class created later or, if simultaneous, the lexicographically first name to improve user experience.
• issues/133693

• Flaking Unit Test Failures in Watch Manager: The TestReflectorNotStoppedOnSlowInitialization unit test intermittently fails due to reflector initialization errors and dynamic resource plugin runtime errors related to a missing "healthy" key during Windows master CI runs. This flake causes instability in test results and requires investigation.
• issues/133698

• Flaky Scheduler Integration Test: The TestEndpointHandlers//readyz scheduler integration test intermittently returns HTTP 500 errors instead of 200 at the /readyz endpoint, causing instability in sig-release-master-blocking jobs since late August 2025. This flake affects the reliability of release blocking tests.
• issues/133700

• Insufficient Access for New Events API: The new events.events.k8s.io API is not included in the default Kubernetes view role, unlike the core events API, resulting in insufficient access permissions for users with the default view role. This discrepancy limits visibility into new event resources.
• issues/133701

• Kubelet Device Resource Allocation Sync Issue: After running a Device Resource Allocation end-to-end test, the kubelet logs errors indicating that unhealthyDevices and endpoints have become out of sync, which should not occur as these states are expected to remain synchronized. This points to a bug in resource state tracking.
• issues/133702

• CRD Status Sub-resource Metadata Loss: Writing to the status sub-resource of a CustomResourceDefinition using a different API version causes metadata.managedFields to be wiped out, removing spec fields that should remain unchanged. This bug affects the integrity of CRD metadata during status updates.
• issues/133704

• Scheduler Device Allocation Bug: The Kubernetes scheduler's device allocation logic for consumable capacity fails to allocate remaining devices if one requested device is already allocated. This flaw in the CmpRequestOverCapacity call causes pods to be stuck in a Pending state during testing with the dra-example-driver.
• issues/133705

• Feature Gate Validation Typo: A typo in the error message for the enableSystemLogQuery feature gate validation incorrectly references enableSystemLogHandler, causing confusion during kubelet configuration validation.
• issues/133713

• Dead Code Elimination Breakage by MethodByName: The use of MethodByName in Kubernetes breaks Go's dead code elimination, significantly increasing binary size for applications using API classes with many methods. A build tag is requested to avoid this call and reduce binary bloat.
• issues/133722

• CSI Plugin Registration Silent Failure: Failure in the handler.RegisterPlugin method does not trigger a retry, causing silent plugin registration failure because actualStateOfWorldUpdater.AddPlugin has already executed. This prevents subsequent registration attempts and leads to plugin registration issues.
• issues/133725

• Kubelet Admission Control Status Confusion: Pods rejected by kubelet admission control initially show clear failure statuses but transition to ContainerStatusUnknown after a kubelet restart, losing container status information. This degrades user experience and complicates distinguishing these from genuine container runtime issues.
• issues/133733

• ResourceQuota Controller Blocked by Aggregated API: The ResourceQuota controller fails to update quotas because it gets stuck waiting for the quota monitor to sync, blocked by aggregated API resources from spdx.softwarecomposition.kubescape.io/v1beta1 that do not support List/Watch properly. This causes the controller to be blocked by misconfigured CRD resources.
• issues/133737

• DRA Extended Resources Testing Requests: Performance, scalability, and monitoring testing are requested for Device Resource Allocation (DRA) extended resources to support their promotion to Beta, referencing related Kubernetes enhancement proposals.
• issues/133757, issues/133758

• CRD Validation FieldPath Inconsistency: The fieldPath rendering in CRD validation rules is inconsistent depending on schema depth, causing validation errors due to differing dot notation in reported paths. This inconsistency affects CRD validation reliability.
• issues/133761

• ResourceSlice Controller E2E Test Flake: The [sig-node] [DRA] ResourceSlice Controller creates slices [ConformanceCandidate] e2e test flakes due to premature timeout while listing ResourceSlice objects, caused by the API server returning an HTTP/2 stream reset error instead of a retryable timeout. This leads to failed assertions and suggests changes to test or retry logic.
• issues/133763

• Kube-proxy Iptables Sync Period Misbehavior: The kube-proxy --iptables-sync-period option does not behave as described; actual synchronization occurs only under specific conditions like changes to the KUBE-PROXY-CHAIN or Endpoints resources, otherwise defaulting to hourly syncs. This behavior is not clearly documented and causes confusion.
• issues/133767

• Kube-proxy IPVS Mode Performance Issue: Syncing a large number of IPVS rules during node initialization causes delays and missing SNAT rules, leading to API server access failures and timeouts for node components relying on the Kubernetes service IP. This performance problem affects cluster stability.
• issues/133773

• Integration Test Flake Due to Non-deterministic Ordering: The TestApply/optional-list-map-key integration test flakes because of non-deterministic ordering of list entries in applied status fields, causing mismatches between expected and actual outputs.
• issues/133780

• API Server Logs "Error getting keys" on Cluster Creation: The Kubernetes API server logs an "Error getting keys" with an "empty key" message from the new cleanKeysIfNeeded method introduced in version 1.34.0, causing errors during cluster creation.
• issues/133787

• Client-go Panic on ConfigMap Listing: The client-go library panics in ListAllByNamespace when listing ConfigMaps due to a nil interface being incorrectly converted to a *v1.ConfigMap, causing application crashes instead of error returns.
• issues/133788

• Kubectl Delete Command Hangs on MTU/PMTU Packet Loss: The kubectl delete command hangs indefinitely because a TCP connection remains established behind a load balancer during severe MTU/PMTU-related packet loss, preventing recognition of pod deletion completion even after network recovery.
• issues/133791

• Kubelet Unsupported on MacOS in Local-Up-Cluster Script: Running hack/local-up-cluster.sh with START_MODE=kubeletonly on MacOS exits because the kubelet is not supported on that operating system.
• issues/133795
