Before upgrading a cluster, all objects in resource.k8s.io/v1alpha1 (ResourceClaim, ResourceClaimTemplate, ResourceClass, PodScheduling) must be deleted. The changes will be internal, so YAML files which create pods and resource claims don't need changes except for the newer
apiVersion. (#116299, @pohly) [SIG API Machinery, Apps, CLI, Node, Scheduling and Testing] -

Upgrades functionality of
kubectl kustomizeas described at https://github.com/kubernetes-sigs/kustomize/releases/tag/kustomize%2Fv5.0.0 and https://github.com/kubernetes-sigs/kustomize/releases/tag/kustomize%2Fv5.0.1.This is a new major release of kustomize, so there are a few backwards-incompatible changes, most of which are rare use cases, bug fixes with side effects, or things that have been deprecated for multiple releases already:
- kubernetes-sigs/kustomize#4911: Drop support for a very old, legacy style of patches. patches used to be allowed to be used as an alias for patchesStrategicMerge in kustomize v3. You now have to use patchesStrategicMerge explicitly, or update to the new syntax supported by patches. See examples in the PR description of kubernetes-sigs/kustomize#4911.
- kubernetes-sigs/kustomize#4731: Remove a potential build-time side-effect in ConfigMapGenerator and SecretGenerator, which loaded values from the local environment under some circumstances, breaking kustomize build's side-effect-free promise. While this behavior was never intended, we deprecated it and are announcing it as a breaking change since it existed for a long time. See also the Eschewed Features documentation.
- kubernetes-sigs/kustomize#4985: If you previously included .git in an AWS or Azure URL, we will no longer automatically remove that suffix. You may need to add an extra / to replace the .git for the URL to properly resolve.
- kubernetes-sigs/kustomize#4954: Drop support for using gh: as a host (e.g. gh:kubernetes-sigs/kustomize). We were unable to find any usage of or basis for this and believe it may have been targeting a custom gitconfig shorthand syntax. (#116598, @natasha41575) [SIG CLI]

Fixes #115825. Kube-proxy will now include the
healthzstate in its response to the LB HC as to avoid indicating to the LB that it should use the node in question when Kube-proxy is not healthy. (#111661, @alexanderConstantinescu) [SIG Network] -
Force deleted pods may fail to terminate until the kubelet is restarted when the container runtime returns an error during termination. We have strengthened testing for runtime failures and now perform a more rigorous reconciliation to ensure static pods (especially those that use fixed UIDs) are restarted. As a side effect of these changes static pods will be restarted with lower latency than before (2s vs 4s, on average) and rapid updates to pod configuration should take effect sooner.
A new metric
kubelet_known_podshas been added at ALPHA stability to report the number of pods a Kubelet is tracking in a number of internal states. Operators may use the metrics to track an excess of pods in the orphaned state that may not be completing. (#113145, @smarterclayton) [SIG API Machinery, Auth, Cloud Provider, Node and Testing] -
From now on, the HPA controller will return an error for the container resource metrics when the feature gate "HPAContainerMetrics" is disabled. As a result, HPA with a container resource metric performs no scale-down and performs only scale-up based on other metrics. (#116043, @sanposhiho) [SIG API Machinery, Apps and Autoscaling]

All container images are available as manifest lists and support the described architectures. It is also possible to pull a specific architecture directly by adding the "-$ARCH" suffix to the container image name.
- A fix in the resource.k8s.io/v1alpha1/ResourceClaim API avoids harmless (?) ".status.reservedFor: element 0: associative list without keys has an element that's a map type" errors in the apiserver. Validation now rejects the incorrect reuse of the same UID in different entries. (#115354, @pohly) [SIG API Machinery]
- CacheSize field in EncryptionConfiguration is not supported for KMSv2 provider (#113121, @aramase) [SIG API Machinery, Auth and Testing]
- K8s.io/client-go/tools/record.EventBroadcaster: after Shutdown() is called, the broadcaster now gives up immediately after a failure to write an event to a sink. Previously it tried multiple times for 12 seconds in a goroutine. (#115514, @pohly) [SIG API Machinery]
- K8s.io/component-base/logs now also supports adding command line flags to a flag.FlagSet. (#114731, @pohly) [SIG Architecture]

A new client side metric
rest_client_request_retries_totalhas been added that tracks the number of retries sent to the server, partitioned by status code, verb, and host (#108396, @tkashem) [SIG API Machinery, Architecture and Instrumentation] -
A new feature has been enabled to improve the performance of the iptables mode of kube-proxy in large clusters. You do not need to take any action, however:
- If you experience problems with Services not syncing to iptables correctly, you can disable the feature by passing
--feature-gates=MinimizeIPTablesRestore=falseto kube-proxy (and file a bug if this fixes it). (This might also be detected by seeing the value of kube-proxy'ssync_proxy_rules_iptables_partial_restore_failures_totalmetric rising.) - If you were previously overriding the kube-proxy configuration for performance reasons, this may no longer be necessary. See https://kubernetes.io/docs/reference/networking/virtual-ips/#optimizing-iptables-mode-performance. (#115138, @danwinship) [SIG Network]
- If you experience problems with Services not syncing to iptables correctly, you can disable the feature by passing

-
Kubelet config file will be backed up to
/etc/kubernetes/tmp/folder withkubeadm-kubelet-configappend with a random suffix as the filename (#114695, @chendave) [SIG Cluster Lifecycle] -
Kubelet no longer creates certain legacy iptables rules by default. It is possible that this will cause problems with some third-party components that improperly depended on those rules. If this affects you, you can run kubelet with
--feature-gates=IPTablesOwnershipCleanup=false, but you should also file a bug against the third-party component. (#114472, @danwinship) [SIG Network] -

-
Scheduler doesn't run plugin's Score method when its PreScore method returned a Skip status. In other words, your PreScore/Score plugin can return a Skip status in PreScore if the plugin does nothing in Score for that Pod. (#115652, @kidddddddddddddddddddddd) [SIG Scheduling]
-
The go version defined in
.go-versionis now fetched when invoking test, build, and code generation targets if the current go version does not match it. Set $FORCE_HOST_GO=y while testing or building to skip this behavior, or set $GO_VERSION to override the selected go version. (#115377, @liggitt) [SIG Testing] -

All container images are available as manifest lists and support the described architectures. It is also possible to pull a specific architecture directly by adding the "-$ARCH" suffix to the container image name.
- Add warnings to the Services API. Kubernetes now warns for Services in the case of:
- Support for the alpha seccomp annotations
seccomp.security.alpha.kubernetes.io/podandcontainer.seccomp.security.alpha.kubernetes.io, deprecated since v1.19, has been completely removed. The seccomp fields are no longer auto-populated when pods with seccomp annotations are created. Pods should use the corresponding pod or containersecurityContext.seccompProfilefield instead. (#114947, @saschagrunert)
- A terminating pod on a node that is not caused by preemption won't prevent kube-scheduler from preempting pods on that node
- Rename 'PreemptionByKubeScheduler' to 'PreemptionByScheduler' (#114623, @Huang-Wei) [SIG Scheduling]
- Added new option to the InterPodAffinity scheduler plugin to ignore existing pods` preferred inter-pod affinities if the incoming pod has no preferred inter-pod affinities. This option can be used as an optimization for higher scheduling throughput (at the cost of an occasional pod being scheduled non-optimally/violating existing pods' preferred inter-pod affinities). To enable this scheduler option, set the InterPodAffinity scheduler plugin arg "ignorePreferredTermsOfExistingPods: true". (#114393, @danielvegamyhre) [SIG API Machinery and Scheduling]
- Added warnings about workload resources (Pods, ReplicaSets, Deployments, Jobs, CronJobs, or ReplicationControllers) whose names are not valid DNS labels. (#114412, @thockin) [SIG API Machinery and Apps]
- K8s.io/component-base/logs: usage of the pflag values in a normal Go flag set led to panics when printing the help message (#114680, @pohly) [SIG Instrumentation]
- Kube-proxy, kube-scheduler and kubelet have HTTP APIs for changing the logging verbosity at runtime. This now also works for JSON output. (#114609, @pohly) [SIG API Machinery, Architecture, Cloud Provider, Instrumentation and Testing]
- Kubeadm: explicitly set
priorityfor static pods withpriorityClassName: system-node-critical(#114338, @champtar) [SIG Cluster Lifecycle] - Kubelet: migrate "--container-runtime-endpoint" and "--image-service-endpoint" to kubelet config (#112136, @pacoxu) [SIG API Machinery, Node and Scalability]
- Kubernetes components that perform leader election now only support using Leases for this. (#114055, @aimuz) [SIG API Machinery, Cloud Provider and Scheduling]
- StatefulSet names must be DNS labels, rather than subdomains. Any StatefulSet which took advantage of subdomain validation (by having dots in the name) can't possibly have worked, because we eventually set
pod.spec.hostnamefrom the StatefulSetName, and that is validated as a DNS label. (#114172, @thockin) [SIG Apps] - The following feature gates for volume expansion GA features have been removed and must no longer be referenced in
--feature-gatesflags: ExpandCSIVolumes, ExpandInUsePersistentVolumes, ExpandPersistentVolumes (#113942, @mengjiao-liu) [SIG API Machinery, Apps and Testing] - The list-type of the alpha resourceClaims field introduced to Pods in 1.26.0 was modified from "set" to "map", resolving an incompatibility with use of this schema in CustomResourceDefinitions and with server-side apply. (#114585, @JoelSpeed) [SIG API Machinery]
- Graduated the
LegacyServiceAccountTokenTrackingfeature gate to Beta. The usage of auto-generated secret-based service account token now produces warnings by default, and relevant Secrets are labeled with a last-used timestamp (label keykubernetes.io/legacy-token-last-used). (#114523, @zshihang) [SIG API Machinery and Auth] - Kube-proxy accepts the ContextualLogging, LoggingAlphaOptions, LoggingBetaOptions feature gates. (#115233, @pohly) [SIG Instrumentation and Network]
- Kube-up now includes CoreDNS version v1.9.3 (#114279, @pacoxu) [SIG Cloud Provider and Cluster Lifecycle]
- Kubeadm: add the experimental (alpha) feature gate EtcdLearnerMode that allows etcd members to be joined as learner and only then promoted as voting members (#113318, @pacoxu) [SIG Cluster Lifecycle]
- Kubectl will display SeccompProfile for pods, containers and ephemeral containers, if values were set. (#113284, @williamyeh) [SIG CLI and Security]
- Kubectl: add e2e test for default container annotation (#115046, @pacoxu) [SIG Architecture, CLI and Testing]
- Kubelet TCP and HTTP probes are more effective using networking resources: conntrack entries, sockets, ... This is achieved by reducing the TIME-WAIT state of the connection to 1 second, instead of the defaults 60 seconds. This allows kubelet to free the socket, and free conntrack entry and ephemeral port associated. (#115143, @aojea) [SIG Network and Node]
- Kubernetes is now built with Go 1.19.5 (#115010, @cpanato) [SIG Release and Testing]
- Make
kubectl-convertbinary linking static (also affects the deb and rpm packages). (#114228, @saschagrunert) [SIG Release] - New metrics
cidrset_cidrs_max_totalandmulticidrset_cidrs_max_totalexpose the max number of CIDRs that can be allocated. (#112260, @aryan9600) [SIG Apps, Instrumentation and Network] - Profiling can now be served on a unix-domain socket by using the
--profiling-pathoption (when profiling is enabled) for security purposes. (#114191, @apelisse) [SIG API Machinery] - Scheduler doesn't run plugin's Filter method when its PreFilter method returned a Skip status. In other words, your PreFilter/Filter plugin can return a Skip status in PreFilter if the plugin does nothing in Filter for that Pod. Scheduler skips NodeAffinity Filter plugin when NodeAffinity Filter plugin has nothing to do with a Pod. It may affect some metrics values related to the NodeAffinity Filter plugin. (#114125, @sanposhiho) [SIG Scheduling, Storage and Testing]
- Scheduler skips InterPodAffinity Filter plugin when InterPodAffinity Filter plugin has nothing to do with a Pod. It may affect some metrics values related to the InterPodAffinity Filter plugin. (#114889, @sanposhiho) [SIG Scheduling and Testing]
- Scheduler volumebinding: leverage PreFilterResult to reduce down to only eligible node(s) for pod with bound claim(s) to local PersistentVolume(s) (#109877, @yibozhuang) [SIG Scheduling, Storage and Testing]
- The MinDomainsInPodTopologySpread feature gate is enabled by default as a Beta feature in 1.27. (#114445, @mengjiao-liu) [SIG Scheduling]
- The
AdvancedAuditingfeature gate was locked to true in v1.27, and will be removed completely in v1.28 (#115163, @SataQiu) [SIG API Machinery] - Updated cAdvisor to v0.47.0 (#114883, @bobbypage) [SIG Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]
- Use HorizontalPodAutoscaler v2 for kubectl (#114886, @a7i) [SIG CLI]
- Verify that the key matches the cert (#113581, @aimuz) [SIG Apps]
- When any scheduler plugin returns an
unschedulableAndUnresolvablestatus inPostFilter, the scheduling cycle terminates immediately for that Pod. (#114699, @kerthcet) [SIG Scheduling and Testing]
- Error message for Pods with requests exceeding limits will have a limit value printed. (#112925, @SergeyKanzhelev) [SIG Apps and Node]
- Deflake a preemption test that may patch Nodes incorrectly. (#114350, @Huang-Wei) [SIG Scheduling and Testing]
- Adding (dry run) and (server dry run) suffixes to kubectl scale command when dry-run is passed (#114252, @ardaguclu) [SIG CLI and Testing]
- Change the error message to "cannot exec into multiple objects at a time" when file passed to kubectl exec contains multiple resources (#114249, @ardaguclu) [SIG CLI and Testing]
- Changing the error message of kubectl rollout restart when subsequent kubectl rollout restart commands are executed within a second (#113040, @ardaguclu) [SIG CLI]
- Client-go: fixes potential data races retrying requests using a custom io.Reader body; with this fix, only requests with no body or with string / []byte / runtime.Object bodies can be retried (#113933, @liggitt) [SIG API Machinery]
- Do not add DisruptionTarget condition by PodGC for pods which are in terminal phase (#115056, @mimowo) [SIG Apps and Testing]
- Do not include preemptor pod metadata in the event message (#114923, @mimowo) [SIG Scheduling]

- Fail CRI connection if service or image endpoint is throwing any error on kubelet startup. (#115102, @saschagrunert) [SIG Node]
- Failed pods associated with a job with
parallelism = 1are recreated by the job controller honoring exponential backoff delay again. However, for jobs withparallelism > 1, pods might be created without exponential backoff delay.

- Fix a bug where when emitting similar Events consecutively, some were rejected by the apiserver. (#114237, @dgrisonnet) [SIG API Machinery]
- Fix a data race when emitting similar Events consecutively (#114236, @dgrisonnet) [SIG API Machinery]
- Fix a regression that the scheduler always goes through all Filter plugins. (#114518, @Huang-Wei) [SIG Scheduling]
- Fix bug in CRD Validation Rules (beta) and ValidatingAdmissionPolicy (alpha) where all admission requests could result in
internal error: runtime error: index out of range [3] with length 3 evaluating rule: <rule name>under certain circumstances. (#114857, @jpbetz) [SIG API Machinery, Auth and Cloud Provider] - Fix clearing of rate-limiter for the queue of checks for cleaning stale pod disruption conditions. The bug could result in the PDB synchronization updates firing too often or the pod disruption cleanups taking too long to happen. (#114770, @mimowo) [SIG Apps]
- Fix: Route controller should update routes with NodeIP changed (#108095, @lzhecheng) [SIG Cloud Provider and Network]
- Fixed CSI PersistentVolumes to allow Secrets names longer than 63 characters. (#114776, @jsafrane) [SIG Apps]
