Changelog since v1.22.13

Important Security Information

This release contains changes that address the following vulnerabilities:

CVE-2022-3172: Aggregated API server can cause clients to be redirected (SSRF)

A security issue was discovered in kube-apiserver that could allow an attacker controlled aggregated API server to redirect client traffic to any URL. This could lead to the client performing unexpected actions as well as leaking the client's credentials to third parties.

There is no mitigation from this issue. Cluster admins should take care to secure aggregated API servers and should not grant access to mutate APIServices to untrusted parties.

Affected Versions:

kube-apiserver v1.25.0
kube-apiserver v1.24.0 - v1.24.4
kube-apiserver v1.23.0 - v1.23.10
kube-apiserver v1.22.0 - v1.22.14
kube-apiserver <= v1.21.?

Fixed Versions:

kube-apiserver v1.25.1
kube-apiserver v1.24.5
kube-apiserver v1.23.11
kube-apiserver v1.22.14

This vulnerability was reported by Nicolas Joly & Weinong Wang from Microsoft

CVSS Rating: Medium (5.1) CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:L/A:L

Changelog since v1.22.11

Changes by Kind

Bug or Regression

Fix a bug that caused the wrong result length when using --chunk-size and --selector together (#110758, @Abirdcfly) [SIG API Machinery and Testing]
Fix bug that prevented the job controller from enforcing activeDeadlineSeconds when set (#110543, @harshanarayana) [SIG Apps]
Fix image pulling failure when IMDS is unavailable in kubelet startup (#110523, @andyzhangx) [SIG Cloud Provider]
Fix printing resources with int64 fields (#110603, @sanchezl) [SIG API Machinery]
Fixed a regression introduced in 1.22.4 where Azure load balancers were not kept up to date with the state of cluster nodes. In particular, nodes that are not in the ready state and are not newly created (i.e. not having the node.cloudprovider.kubernetes.io/uninitialized taint) now get removed from Azure load balancers. (#109933, @ricky-rav) [SIG Cloud Provider]
Fixed potential scheduler crash when scheduling with unsatisfied nodes in PodTopologySpread. (#110984, @kerthcet) [SIG Scheduling]
Kubeadm: fix the bug that configurable KubernetesVersion not respected during kubeadm join (#111024, @SataQiu) [SIG Cluster Lifecycle]
Reduced time taken to sync proxy rules on Windows kube-proxy with kernelspace mode (#110701, @daschott) [SIG Network and Windows]
Updated cAdvisor to v0.39.4 to pick up a kubelet fix where network metrics can be missing in some cases when used with containerd (#111014, @bobbypage) [SIG Node]

Changelog since v1.22.10

Changes by Kind

Bug or Regression

Bug Fix: Kube-proxy dropped endpointSlice's local endpoints when upgrading from 1.20 to 1.22 (#110245, @xh4n3) [SIG Network]
EndpointSlices marked for deletion are now ignored during reconciliation. (#110482, @aryan9600) [SIG Apps and Network]
Fixed a kubelet issue that could result in invalid pod status updates to be sent to the api-server where pods would be reported in a terminal phase but also report a ready condition of true in some cases. (#110481, @bobbypage) [SIG Node and Testing]
Pods will now post their readiness during termination. (#110418, @aojea) [SIG Network, Node and Testing]

Changelog since v1.22.8

Changes by Kind

Bug or Regression

Fixed a regression that could incorrectly reject pods with OutOfCpu errors if they were rapidly scheduled after other pods were reported as complete in the API. The Kubelet now waits to report the phase of a pod as terminal in the API until all running containers are guaranteed to have stopped and no new containers can be started. Short-lived pods may take slightly longer (~1s) to report Succeeded or Failed after this change. (#108749, @bobbypage) [SIG Apps, Node and Testing]
Fixes error handling in a kubectl method used in downstream packages. (#108520, @heybronson) [SIG CLI]

Changelog since v1.22.7

Changes by Kind

API Change

Fixes a regression in v1beta1 PodDisruptionBudget handling of "strategic merge patch"-type API requests for the selector field. Prior to 1.21, these requests would merge matchLabels content and replace matchExpressions content. In 1.21, patch requests touching the selector field started replacing the entire selector. This is consistent with server-side apply and the v1 PodDisruptionBudget behavior, but should not have been changed for v1beta1. (#108141, @liggitt) [SIG Auth and Testing]

Feature

Kubernetes is now built with Golang 1.16.15 (#108564, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]

Bug or Regression

Bump sigs.k8s.io/apiserver-network-proxy/konnectivity-client to v0.0.30, fixing goroutine leaks in kube-apiserver. (#108439, @andrewsykim) [SIG API Machinery, Auth and Cloud Provider]
Fix static pod restarts in cases where the container is not present. (#108189, @rphillips) [SIG Node]
Fixes a bug where a partial EndpointSlice update could cause node name information to be dropped from endpoints that were not updated. (#108202, @robscott) [SIG Network]
Fixes a regression in the kubelet restarting static pods. (#108303, @rphillips) [SIG Node and Testing]
Increase Azure ACR credential provider timeout (#108209, @andyzhangx) [SIG Cloud Provider]

Changelog since v1.22.4

Changes by Kind

Feature

Kubernetes is now built with Golang 1.16.11 (#106837, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]
Kubernetes is now built with Golang 1.16.12 (#106982, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]
Update golang.org/x/net to v0.0.0-20211209124913-491a49abca63 (#106960, @cpanato) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]

Bug or Regression

A pod that the Kubelet rejects was still considered as being accepted for a brief period of time after rejection, which might cause some pods to be rejected briefly that could fit on the node. A pod that is still terminating (but has status indicating it has failed) may also still be consuming resources and so should also be considered. (#104918, @ehashman) [SIG Node]
Fix: skip instance not found when decoupling vmss from lb (#105836, @nilo19) [SIG Cloud Provider]
Kubeadm: allow the "certs check-expiration" command to not require the existence of the cluster CA key (ca.key file) when checking the expiration of managed certificates in kubeconfig files. (#106930, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: during execution of the "check expiration" command, treat the etcd CA as external if there is a missing etcd CA key file (etcd/ca.key) and perform the proper validation on certificates signed by the etcd CA. Additionally, make sure that the CA for all entries in the output table is included - for both certificates on disk and in kubeconfig files. (#106925, @neolit123) [SIG Cluster Lifecycle]
Respect grace period when updating static pods. (#106394, @gjkim42) [SIG Node and Testing]
Reverts graceful node shutdown to match 1.21 behavior of setting pods that have not yet successfully completed to "Failed" phase if the GracefulNodeShutdown feature is enabled in kubelet. The GracefulNodeShutdown feature is beta and must be explicitly configured via kubelet config to be enabled in 1.21+. This changes 1.22 and 1.23 behavior on node shutdown to match 1.21. If you do not want pods to be marked terminated on node shutdown in 1.22 and 1.23, disable the GracefulNodeShutdown feature. (#106899, @bobbypage) [SIG Node]
Scheduler's assumed pods have 2min instead of 30s to receive nodeName pod updates (#106633, @ahg-g) [SIG Scheduling]

Changelog since v1.22.3

Changes by Kind

Feature

Kubernetes is now built with Golang 1.16.10 (#106223, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]
Update debian-base, debian-iptables, setcap images to pick up CVE fixes
- Debian-base to v1.9.0
- Debian-iptables to v1.6.7
- setcap to v2.0.4 (#106143, @cpanato) [SIG Release and Testing]

Failing Test

Fixes hostpath storage e2e tests within SELinux enabled env (#105786, @Elbehery) [SIG Testing]

Bug or Regression

EndpointSlice Mirroring controller now cleans up managed EndpointSlices when a Service selector is added (#106132, @robscott) [SIG Apps, Network and Testing]
Fix a bug that --disabled-metrics doesn't function well. (#105793, @Huang-Wei) [SIG API Machinery, Cluster Lifecycle and Instrumentation]
Fix a panic in kubectl when creating secrets with an improper output type (#106356, @lauchokyip) [SIG CLI]
Fix concurrent map access causing panics when logging timed-out API calls. (#106112, @marseel) [SIG API Machinery]
Fix kube-proxy regression on UDP services because the logic to detect stale connections was not considering if the endpoint was ready. (#106239, @aojea) [SIG Network and Testing]
Fix scoring for NodeResourcesBalancedAllocation plugins when nodes have containers with no requests. (#106081, @ahmad-diaa) [SIG Scheduling]
Support more than 100 disk mounts on Windows (#105673, @andyzhangx) [SIG Storage and Windows]
The --leader-elect* CLI args are now honored correctly in scheduler. (#106130, @Huang-Wei) [SIG Scheduling]
The kube-proxy sync_proxy_rules_iptables_total metric now gives the correct number of rules, rather than being off by one.

Fixed multiple iptables proxy regressions introduced in 1.22:
- When using Services with SessionAffinity, client affinity for an endpoint now gets broken when that endpoint becomes non-ready (rather than continuing until the endpoint is fully deleted).
- Traffic to a service IP now starts getting rejected (as opposed to merely dropped) as soon as there are no longer any usable endpoints, rather than waiting until all of the terminating endpoints have terminated even when those terminating endpoints were not being used.
- Chains for endpoints that won't be used are no longer output to iptables, saving a bit of memory/time/cpu. (#106373, @aojea) [SIG Network]
Watch requests that are delegated to aggregated apiservers no longer reserve concurrency units (seats) in the API Priority and Fairness dispatcher for their entire duration. (#105827, @benluddy) [SIG API Machinery]

CVSS Rating: High (8.8) CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Changes by Kind

Feature

Kubernetes is now built with Golang 1.16.8 (#104905, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]

Bug or Regression

Fix Job tracking with finalizers for more than 500 pods, ensuring all finalizers are removed before counting the Pod. (#104876, @alculquicondor) [SIG Apps]
Fix: skip case sensitivity when checking Azure NSG rules fix: ensure InstanceShutdownByProviderID return false for creating Azure VMs (#104446, @feiskyer) [SIG Cloud Provider]
Fixed occasional pod cgroup freeze when using cgroup v1 and systemd driver. (#104529, @kolyshkin) [SIG Node]
Fixes a regression that could cause panics in LRU caches in controller-manager, kubelet, kube-apiserver, or client-go EventSourceObjectSpamFilter (#104469, @liggitt) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Storage]
When using kubectl replace (or the equivalent API call) on a Service, the caller no longer needs to do a read-modify-write cycle to fetch the allocated values for .spec.clusterIP and .spec.ports[].nodePort. Instead the API server will automatically carry these forward from the original object when the new object does not specify them. (#104672, @thockin) [SIG Network]

Changelog since v1.21.0

What's New (Major Themes)

Removal of several beta Kubernetes APIs

A number of APIs are no longer serving specific Beta versions in favour of the GA version of those APIs. All existing objects can be interacted with via general availability APIs. This removal includes beta versions of ValidatingWebhookConfiguration, MutatingWebhookConfiguration, CustomResourceDefinition, APIService, TokenReview, SubjectAccessReview, CertificateSigningRequest, Lease, Ingress, and IngressClass APIs. For the full list check out Deprecated API Migration Guide and the blog post Kubernetes API and Feature Removals In 1.22: Here’s What You Need To Know.

Kubernetes release cadence change

We all have to adapt to change in our lives, and especially so in the past year. The Kubernetes release team was also affected from the COVID-19 pandemic and has listened to its user base regarding the number of releases in a calendar year. From April 23, 2021 it was made official that Kubernetes release cadence has reduced from 4 releases per year to 3 releases per year.

You can read more in the official blog post Kubernetes Release Cadence Change: Here’s What You Need To Know.

External credential providers

Kubernetes client credential plugins have been in beta since 1.11, a few eons ago. With the release of Kubernetes 1.22, this feature set graduates to stable. The GA feature set includes improved support for plugins that provide interactive login flows. This release also contains a number of bug fixes to the feature set. Aspiring plugin authors can look at sample-exec-plugin as a way to get started.

Related to this topic, the in-tree Azure and GCP authentication plugins have been deprecated in favor of out-of-tree implementations.

Server-side Apply graduates to GA

Server-side Apply is a new object merge algorithm, as well as tracking of field ownership, running on the Kubernetes API server. Server-side Apply helps users and controllers manage their resources via declarative configurations. It allows them to create and/or modify their objects declaratively, simply by sending their fully specified intent. After being in beta for a couple releases, Server-side Apply is now generally available.

Container Storage Interface graduations

CSI support for Windows nodes moves to GA in the 1.22 release. In Kubernetes v1.22, Windows privileged containers are only an alpha feature. To allow using CSI storage on Windows nodes, CSIProxy enables CSI node plugins to be deployed as unprivileged pods, using the proxy to perform privileged storage operations on the node.

Another feature moving to GA in v1.22 is CSI Service Account Token support. This feature allows CSI drivers to use pods' bound service account tokens instead of a more privileged identity. It also provides control over to re-publishing these volumes, so that short-lived tokens can be refreshed.

SIG Windows development tools

To grow the developer community, SIG Windows released multiple tools. The new tools support multiple CNI providers (Antrea, Calico), can run on multiple platforms (any vagrant compatible provider, such as Hyper-V, VirtualBox, or vSphere). There is also a new way to run bleeding edge Windows features from scratch by compiling the windows kubelet and kube-proxy, then using them along with daily builds of other Kubernetes components.

Deploy a more secure control plane with kubeadm

A new alpha feature allows running the kubeadm control plane components as non-root users. This is a long requested security measure in kubeadm. To try it you must enable the kubeadm-specific RootlessControlPlane feature gate. When you deploy a cluster using this alpha feature, your control plane runs with lower privileges.

A new v1beta3 configuration API. It iterates over v1beta2 by adding some long requested features and deprecating some existing ones. The V1beta3 is now the preferred API version; the v1beta2 API also remains available and is not yet deprecated.

etcd moves to version 3.5.0

Kubernetes' default backend storage, etcd, has a new release 3.5.0 and the community embraced it. The new release comes with improvements to the Security, performance, monitoring and developer experience. There are numerous bug fixes to lease objects causing memory leaks, and compact operation causing deadlocks and more. A couple of new features are also introduced like the migration to structured logging and build in log rotation. The release comes with a detailed future roadmap to implement a solution to traffic overload. A full and detailed list of changes can be read in the 3.5.0 release announcement.

Kubernetes Node system swap support

Every system administrator or Kubernetes user has been in the same boat regarding setting up and using Kubernetes: disable swap space. With the release of Kubernetes 1.22, alpha support is available to run nodes with swap memory. This change lets administrators opt in to configuring swap on Linux nodes, treating a portion of block storage as additional virtual memory.

Cluster-wide seccomp defaults

A new alpha feature gate SeccompDefault has been added to the kubelet, together with a corresponding command line flag --seccomp-default and kubelet configuration. If both are enabled, then the kubelet's behavior changes for pods that don't explicitly set a seccomp profile. With cluster-wide seccomp defaults, the kubelet uses the RuntimeDefault seccomp profile by default, rather than than Unconfined. This allows enhancing the default cluster wide workload security of the Kubernetes deployment. Security administrators will now sleep better knowing there is some security by default for the workloads.

To learn more about the feature, please refer to the official seccomp tutorial.

Quality of Service for memory resources

Originally, Kubernetes used the v1 cgroups API. With that design, the QoS class for a pod only applied to CPU resources (such as cpu_shares). The Kubernetes cgroup manager uses memory.limit_in_bytes in v1 cgroups to limit the memory capacity for a container, and uses oom_scores to recommend an order for killing container processes if an out-of-memory event occurs. This implementation has shortcomings: for Guaranteed pods, memory can not be fully reserved, and the page cache is at risk of being recycled. For Burstable pods, overcommitting memory (setting request less than limit ) could increase the risk of a container being killed when the Linux kernel detects an out of memory condition.

As an alpha feature, Kubernetes v1.22 can use the cgroups v2 API to control memory allocation and isolation. This feature is designed to improve workload and node availability when there is contention for memory resources.

API changes and improvements for ephemeral containers

The API used to create Ephemeral Containers changed in 1.22. The Ephemeral Containers feature is alpha and disabled by default, and the new API does not work with clients that attempt to use the old API.

For stable features, the kubectl tool follows the Kubernetes version skew policy; however, kubectl v1.21 and older do not support the new API for ephemeral containers. Users who create ephemeral containers using kubectl debug should note that kubectl version 1.22 will attempt to fall back to the old API; older versions of kubectl will not work with cluster versions of 1.22 or later. Please update kubectl to 1.22 if you wish to use kubectl debug with a mix of cluster versions.

Known Issues

CPU and Memory manager are not working correctly for Guaranteed Pods with multiple containers

A regression bug was found where guaranteed Pods with multiple containers do not work properly with set allocations for CPU, Memory, and Device manager. The fix will be availability in coming releases.

`CSIMigrationvSphere` feature gate has not migrated to new CRD APIs

If CSIMigrationvSphere feature gate is enabled, user should not upgrade to Kubernetes v1.22. vSphere CSI Driver does not support Kubernetes v1.22 yet because it uses v1beta1 CRD APIs. Support for v1.22 will be added at a later release. Check the following document for supported Kubernetes releases for a given vSphere CSI Driver version.

Workloads that saturate nodes with pods may see pods that fail due to node admission

1.22 addressed a long-standing issue in the Kubelet where terminating pods were vulnerable to race conditions leading to early shutdown, resource leaks, or long delays in actually completing pod shutdown. As a consequence of this change the Kubelet now correctly takes into account the resources of running and terminating pods when deciding to accept new pods, since terminating pods are still holding on to those resources. This stricter handling may surface to end users as pod rejections when creating pods that are scheduled to mostly full nodes that have other terminating pods holding the resources the new pods need. The most likely error would be a pod set to Failed phase with reason set to OutOfCpu or OutOfMemory, but any resource on the node that has some fixed limit (including persistent volume counts on cloud nodes, exclusive CPU cores, or unique hardware devices) could trigger the failure. While this behavior is correct it reduces the throughput of pod execution and creates user-visible warnings - future versions of Kubernetes will minimize the likelihood users see pod failures due to this issue. In general, any automation that creates pods must take Kubelet rejections into account, and should be designed to retry and backoff where necessary.

Etcd v3.5.[0-2] data corruption

Data corruption issue was found in etcd v3.5.0 release that was shipped with 1.22 Kubernetes release. Please read up-to-date production recommendations for etcd.

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

Audit log files are now created with a mode of 0600. Existing file permissions will not be changed. If you need the audit file to be readable by a non-root user, you can pre-create the file with the desired permissions. (#95387, @JAORMX) [SIG API Machinery and Auth]
CSI migration of AWS EBS volumes requires AWS EBS CSI driver ver. 1.0 that supports allowAutoIOPSPerGBIncrease parameter in StorageClass. (#101082, @jsafrane)
Conformance image is now built with Distroless. Users running Conformance testing should rely on container entrypoint instead of manual invocation to /run_e2e.sh or /gorunner, as they are now deprecated and will be removed in 1.25 release. Invoking ginkgo and e2e.test are still supported through overriding entrypoint (docker) or defining container spec.command (kubernetes). (#99178, @wilsonehusin)
Default StreamingProxyRedirects to disabled. If there is a >= 2 version skew between master and nodes, and the old nodes were enabling --redirect-container-streaming, this will break them. In this case, the StreamingProxyRedirects can still be manually enabled. (#101647, @pacoxu)
Intree volume plugin scaleIO support has been completely removed from Kubernetes. (#101685, @Jiawei0227)
Kubeadm: remove the automatic detection and matching of cgroup drivers for Docker. For new clusters if you have not configured the cgroup driver explicitly you might get a failure in the kubelet on driver mismatch (kubeadm clusters should be using the systemd driver). Also remove the IsDockerSystemdCheck preflight check (warning) that checks if the Docker cgroup driver is set to systemd. Ideally such detection / coordination should be on the side of CRI implementers and the kubelet (tracked here). Please see the page on how to configure cgroup drivers with kubeadm manually (#99647, @neolit123)
Kubeadm: the flag --cri-socket is no longer allowed in a mixture with the flag --config. Please use the kubeadm configuration for setting the CRI socket for a node using {Init|Join}Configuration.nodeRegistration.criSocket. (#101600, @KofClubs)
Newly provisioned PVs by Azure disk will no longer have the beta FailureDomain label. Azure disk volume plugin will start to have GA topology label instead. (#101534, @kassarl)
Scheduler's CycleState now embeds internal read/write locking inside its Read() and Write() functions. Meanwhile, Lock() and Unlock() function are removed. Scheduler plugin developers are now required to remove CycleState#Lock() and CycleState#Unlock(). Just simply use Read() and Write() as they're natively thread-safe now. (#101542, @Huang-Wei)
The CSIMigrationVSphereComplete feature flag is removed. InTreePluginvSphereUnregister will be the way moving forward. (#101272, @Jiawei0227)
The flag --experimental-patches is now deprecated and will be removed in a future release. You can migrate to using the new flag --patches. Add a new field {Init|Join}Configuration.patches.directory that can be used for the same purpose. For init and join it is now recommended that you migrate to configure patches via {Init|Join}Configuration.patches.directory. For the time being, these flags can be mixed with --config, but that might change in the future. On a command line, the last *patches flag takes precedence over previous flags and the value in config. kubeadm upgrade --patches will continue to be the only available option, since upgrade does not support a configuration file yet. (#103063, @neolit123)

Changes by Kind

Deprecation

Controller-manager: the following flags have no effect and would be removed in v1.24:
- --port
- --address The insecure port flags --port may only be set to 0 now.
In addtion, please be careful that:
- controller-manager MUST start with --authorization-kubeconfig and --authentication-kubeconfig correctly set to get authentication/authorization working.
- liveness/readiness probes to controller-manager MUST use HTTPS now, and the default port has been changed to 10257.
- Applications that fetch metrics from controller-manager should use a dedicated service account which is allowed to access nonResourceURLs /metrics. (#96216, @knight42) [SIG API Machinery, Cloud Provider, Instrumentation and Testing]
Deprecate --record flag in kubectl. The --record flag is being replaced with the mechanism which annotates HTTP requests with kubectl command details. (#102873, @soltysh)
E2e.test: removed the --viper-config flag. If you were previously using this to pass flags to e2e.test via a file, you will need to pass them directly on the command line, e.g. e2e.test --e2e-output-dir. (#102598, @dims)
For kubeadm: remove the ClusterStatus API from v1beta3 and its management in the kube-system/kubeadm-config ConfigMap. This method of keeping track of what API endpoints exists in the cluster was replaced (in a prior release) by a method to annotate the etcd Pods that kubeadm creates in "stacked etcd" clusters. The following CLI sub-phases are deprecated and are now a NO-OP: for kubeadm join: "control-plane-join/update-status", for kubeadm reset: "update-cluster-status". Unless you are using these phases explicitly, you should not be affected. (#101915, @neolit123)
Kubeadm: remove the deprecated --csr-only and --csr-dir flags from kubeadm init phase certs. Deprecate the same flags under kubeadm certs renew. In both the cases the command kubeadm certs generate-csr should be used instead. (#102108, @neolit123)
Kubeadm: Remove the deprecated command kubeadm alpha kubeconfig. Please use kubeadm kubeconfig instead. (#101938, @knight42)
Kubeadm: Remove the deprecated hyperkube image support in v1beta3. This implies removal of ClusterConfiguration.UseHyperKubeImage. (#101537, @neolit123)
Kubeadm: Remove the field ClusterConfiguration.DNS.Type in v1beta3 since CoreDNS is the only supported DNS type. (#101547, @neolit123)
Kubeadm: remove the deprecated command kubeadm config view. A replacement for this command is kubectl get cm -n kube-system kubeadm-config -o=jsonpath="{.data.ClusterConfiguration}" (#102071, @neolit123)
Kubeadm: remove the deprecated flag '--image-pull-timeout' for 'kubeadm upgrade apply' command (#102093, @SataQiu) [SIG Cluster Lifecycle]
Kubeadm: remove the deprecated flag --insecure-port from the kube-apiserver manifest that kubeadm manages. The flag had no effect since 1.20, since the insecure serving of the component was disabled in the same version. (#102121, @pacoxu)
Kubeadm: remove the deprecated kubeadm API v1beta1. Introduce a new kubeadm API v1beta3. See kubeadm/v1beta3 for a list of changes since v1beta2. Note that v1beta2 is not yet deprecated, but will be in a future release. (#101129, @neolit123)
Newly provisioned PVs by vSphere in-tree plugin will no longer have the beta FailureDomain label. vSphere volume plugin will start to have GA topology label (#102414, @divyenpatel)
Removal of the CSI NodePublish path by the kubelet is deprecated. This must be done by the CSI plugin according to the CSI spec. (#101441, @dobsonj)
Remove support for the Service topologyKeys field (alpha) and the kube-proxy implementation of it. This field was deprecated several cycles ago. This functionality is replaced by the combination of automatic topology hints per-endpoint (alpha) and the Service internalTrafficPolicy field (alpha). (#102412, @andrewsykim)
The PodUnknown phase is now deprecated. (#95286, @SergeyKanzhelev)
The storageos, quobyte and flocker storage volume plugins are deprecated and will be removed in a later release. (#101773, @Jiawei0227)
The deprecated flag --hard-pod-affinity-symmetric-weight and --scheduler-name have been removed from kube-scheduler. Use ComponentConfig instead to configure those parameters. (#102805, @ahg-g)
The feature Dynamic Kubelet Configuration is deprecated and kubelet will report warning when the flag --dynamic-config-dir is used. Feature gate DynamicKubeletConfig is disabled out of the box and needs to be explicitly enabled. (#102966, @SergeyKanzhelev) [SIG Cloud Provider, Instrumentation and Node]
The in-tree azure and gcp auth plugins have been deprecated. The https://github.com/Azure/kubelogin and gcloud commands serve as out-of-tree replacements via the kubectl/client-go credential plugin mechanism. (#102181, @enj) [SIG API Machinery and Auth]
The ingress v1beta1 has been deprecated. (#102030, @aojea)

API Change

A new score extension for NodeResourcesFit plugin that merges the functionality of NodeResourcesLeastAllocated, NodeResourcesMostAllocated, RequestedToCapacityRatio plugins, which are marked as deprecated as of v1beta2. In v1beta1, the three plugins can still be used in v1beta1 but not at the same time with the score extension of NodeResourcesFit. (#101822, @yuzhiquan)
A value of Auto is now a valid for the service.kubernetes.io/topology-aware-hints annotation. (#100728, @robscott)
Add DataSourceRef alpha field to PVC spec, which allows contents other than PVCs and VolumeSnapshots to be data sources. (#103276, @bswartz)
Add PersistentVolumeClaimDeletePoilcy to StatefulSet API. (#99378, @mattcary)
Add a new Priority and Fairness rule that exempts all probes (/readyz, /healthz, /livez) to prevent restarting of healthy kube-apiserver instance by kubelet. (#100678, @tkashem)
Add alpha support for HostProcess containers on Windows (#99576, @marosset) [SIG API Machinery, Apps, Node, Testing and Windows]
Add distributed tracing to the kube-apiserver. It is can be enabled with the feature gate APIServerTracing (#94942, @dashpole)
Add three metrics to the job controller to monitor if a job works in healthy condition. IndexedJob has been promoted to Beta. (#101292, @AliceZhang2016)
Added field .status.uncountedTerminatedPods to the Job resource. This field is used by the job controller to keep track of finished pods before adding them to the Job status counters. Pods created by the job controller get the finalizer batch.kubernetes.io/job-tracking Jobs that are tracked using this mechanism get the annotation batch.kubernetes.io/job-tracking. This is a temporary measure. Two releases after this feature graduates to beta, the annotation won't be added to Jobs anymore. (#98817, @alculquicondor)
Added new kubelet alpha feature SeccompDefault. This feature enables falling back to the RuntimeDefault (former runtime/default) seccomp profile if nothing else is specified in the pod/container SecurityContext or the pod annotation level. To use the feature, enable the feature gate as well as set the kubelet configuration option SeccompDefault (--seccomp-default) to true. (#101943, @saschagrunert) [SIG Node]
Adds the ReadWriteOncePod access mode for PersistentVolumes and PersistentVolumeClaims. Restricts volume access to a single pod on a single node. (#102028, @chrishenzie)
Alpha swap support can now be enabled on Kubernetes nodes with the NodeSwapEnabled feature flag. See KEP-2400 for details. (#102823, @ehashman)
Because of the implementation logic of time.Format in golang, the displayed time zone is not consistent. (#102366, @cndoit18)
Corrected the documentation for escaping dollar signs in a container's env, command and args property. (#101916, @MartinKanters) [SIG Apps]
Enable MaxSurge for DaemonSet by default. (#101742, @ravisantoshgudimetla)
Enforce the ReadWriteOncePod PVC access mode during scheduling (#103082, @chrishenzie)
Ephemeral containers are now allowed to configure a securityContext that differs from that of the Pod. Cluster administrators should ensure that security policy controllers support EphemeralContainers before enabling this feature in clusters. (#99023, @verb)
Exec plugin authors can override default handling of standard input via new interactiveMode kubeconfig field. (#99310, @ankeesler)
If someone had the ProbeTerminationGracePeriod alpha feature enabled in 1.21, they should update/delete any workloads/pods with probe terminationGracePeriods < 1 before upgrading (#103245, @wzshiming)
Improved parsing of label selectors (#102188, @alculquicondor) [SIG API Machinery]
Introduce minReadySeconds api to the StatefulSets. (#100842, @ravisantoshgudimetla)
Introducing Memory quality of service support with cgroups v2 (Alpha). The MemoryQoS feature is now in Alpha. This allows kubelet running with cgroups v2 to set memory QoS at container, pod and QoS level to protect and guarantee better memory quality. This feature can be enabled through feature gate Memory QoS. (#102970, @borgerli)
Kube API server accepts Impersonate-Uid header to impersonate a user with a specific UID, in the same way that you can currently use Impersonate-User, Impersonate-Group and Impersonate-Extra. (#99961, @margocrawf)
Kube-apiserver: --service-account-issuer can be specified multiple times now, to enable non-disruptive change of issuer. (#101155, @zshihang) [SIG API Machinery, Auth, Node and Testing]
Kube-controller-manager: the --horizontal-pod-autoscaler-use-rest-clients flag and Heapster support in the horizontal pod autoscaler, deprecated since 1.12, is removed. (#90368, @serathius)
Kube-scheduler: a plugin enabled in a v1beta2 configuration file takes precedence over the default configuration for that plugin. This simplifies enabling default plugins with custom configuration without needing to explicitly disable those default plugins. (#99582, @chendave)
New node-high priority-level has been added to Suggested API Priority and Fairness configuration.(#101151, @mborsz)
NodeSwapEnabled feature flag was renamed to NodeSwap

The flag was only available in the 1.22.0-beta.1 release, and the new flag should be used going forward. (#103553, @ehashman) [SIG Node]
Omit comparison with boolean constant (#101523, @chuntaochen) [SIG CLI and Cloud Provider]
Removed the feature flag for probe-level termination grace period from Kubelet. If a user wants to disable this feature on already created pods, they will have to delete and recreate the pods. (#103168, @raisaat) [SIG Apps and Node]
Revert addition of Add PersistentVolumeClaimDeletePoilcy to StatefulSetAPI. (#103747, @mattcary)
Scheduler could be configured to consider new resources beside CPU and memory, GPU for example, for the score plugin of NodeResourcesBalancedAllocation. (#101946, @chendave) [SIG Scheduling]
Server Side Apply now treats all Selector fields as atomic (meaning the entire selector is managed by a single writer and updated together), since they contain interrelated and inseparable fields that do not merge in intuitive ways. (#97989, @Danil-Grigorev) [SIG API Machinery]
Suspend Job feature graduated to beta. Added the action label to Job controller sync metrics job_sync_total and job_sync_duration_seconds. (#102022, @adtac)
The API documentation for the DaemonSet's spec.updateStrategy.rollingUpdate.maxUnavailable field was corrected to state that the value is rounded up. (#101296, @Miciah)
The CSIServiceAccountToken graduates to Ga and is unconditionally enabled. (#103001, @zshihang)
The CertificateSigningRequest.certificates.k8s.io API supports an optional expirationSeconds field to allow the client to request a particular duration for the issued certificate. The default signer implementations provided by the Kubernetes controller manager will honor this field as long as it does not exceed the --cluster-signing-duration flag. (#99494, @enj)
The EndpointSlicen Mirroring controller no longer mirrors the last-applied-configuration annotation created by kubectl to update EndpointSlices. (#102731, @sharmarajdaksh)
The NetworkPolicyEndPort is graduated to beta and is enabled by default. (#102834, @rikatz)
The PodDeletionCost feature has been promoted to beta, and enabled by default. (#101080, @ahg-g)
The Server Side Apply treats certain structs as atomic. Meaning the entire selector field is managed by a single writer and updated together. (#100684, @Jefftree)
The ServiceAppProtocol feature gate has been removed. It reached GA in Kubernetes (#103190, @robscott)
The TerminationGracePeriodSeconds on pod specs and container probes should not be negative. Negative values of TerminationGracePeriodSeconds will be treated as the value 1s on the delete path. Immutable field validation will be relaxed in order to update negative values. In a future release, negative values will not be permitted. (#98866, @wzshiming)
The kube-scheduler component config v1beta2 API available Three scheduler plugins deprecated (NodeLabel, ServiceAffinity, NodePreferAvoidPods). (#99597, @adtac)
The pod/eviction subresource now accepts policy/v1 eviction requests in addition to policy/v1beta1 eviction requests (#100724, @liggitt)
The podAffinity, NamespaceSelector and the associated CrossNamespaceAffinity quota scope features graduate to Beta and they are now enabled by default. (#101496, @ahg-g)
The pods/ephemeralcontainers API now returns and expects a Pod object instead of EphemeralContainers. This is incompatible with the previous alpha-level API. (#101034, @verb) [SIG Apps, Auth, CLI and Testing]
The v1.Node and .status.images[].names are now optional. (#102159, @roycaihw)
The deprecated flag --algorithm-provider has been removed from kube-scheduler. Use instead ComponentConfig to configure the set of enabled plugins. (#102239, @Haleygo)
The options --ssh-user and --ssh-key are removed. They only functioned on GCE, and only in-tree. Use the apiserver network proxy instead. (#102297, @deads2k)
Track Job completion through status and Pod finalizers, removing dependency on Pod tombstones. (#98238, @alculquicondor) [SIG API Machinery, Apps, Auth and Testing]
Track ownership of scale subresource for all scalable resources i.e. Deployment, ReplicaSet, StatefulSet, ReplicationController, and Custom Resources. (#98377, @nodo) [SIG API Machinery and Testing]

Feature

A system-cluster-critical pod should not get a low OOM Score.

As of now both system-node-critical and system-cluster-critical pods have -997 OOM score, making them one of the last processes to be OOMKilled. By definition system-cluster-critical pods can be scheduled elsewhere if there is a resource crunch on the node where as system-node-critical pods cannot be rescheduled. This was the reason for system-node-critical to have higher priority value than system-cluster-critical. This change allows only system-node-critical priority class to have low OOMScore.

action required If the user wants to have the pod to be OOMKilled last and the pod has system-cluster-critical priority class, it has to be changed to system-node-critical priority class to preserve the existing behavior (#99729, @ravisantoshgudimetla)
API Server tracing can now trace re-entrant api requests. (#103218, @dashpole) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]
APIServerTracing now collects spans from etcd client calls, and propagates context to etcd. (#103216, @dashpole) [SIG API Machinery, Cloud Provider and Instrumentation]
APIServerTracing now collects spans from outgoing requests to admission webhooks. (#103601, @dashpole) [SIG API Machinery]
Add a namespace label for all apiserver_admission_* metrics. Expand the histogram range to 0-10s for all apiserver_admission_*_duration_seconds metrics. (#101208, @voutcn)
Add unified map on CRI to support cgroup v2. Refer to https://github.com/opencontainers/runtime-spec/blob/master/config-linux.md#unified. (#102578, @payall4u)
Added BinaryData description to kubectl describe command. (#100568, @lauchokyip)
Added a new metric apiserver_flowcontrol_request_concurrency_in_use that shows the number of seats (concurrency) occupied by the currently executing requests in the API Priority and Fairness system. (#102795, @tkashem)
Added field-selector option for kubectl top pod (#102155, @lauchokyip) [SIG CLI]
Added new metrics about API Priority and Fairness. Each one has a label priority_level. The last two also have a label bound taking values min and `max.
- apiserver_flowcontrol_current_r: R(the time of the last change in state of the queues)
- apiserver_flowcontrol_dispatch_r: R(the time of the latest request dispatch)
- apiserver_flowcontrol_latest_s: S(the request last dispatched) = R(when that request starts executing in the virtual world)
- apiserver_flowcontrol_next_s_bounds: min and max next S among non-empty queues
- apiserver_flowcontrol_next_discounted_s_bounds: min and max next S - (sum [over requests executing] width * estimatedDuration) among non-empty queues (#102859, @MikeSpreitzer) [SIG API Machinery and Instrumentation]
Adding --restart-kubelet flag on E2E Node test suite (#97028, @knabben) [SIG Node and Testing]
Adds feature gate KubeletInUserNamespace which enables support for running kubelet in a user namespace.

The user namespace has to be created before running kubelet. All the node components such as CRI need to be running in the same user namespace.

When the feature gate is enabled, kubelet ignores errors that happens during setting the following sysctl values: vm.overcommit_memory, vm.panic_on_oom, kernel.panic, kernel.panic_on_oops, kernel.keys.root_maxkeys, kernel.keys.root_maxbytes. (These sysctl values for the host, not for the containers)

kubelet also ignores an error during opening /dev/kmsg. This feature gate also allows kube-proxy to ignore an error during setting RLIMIT_NOFILE.

This feature gate is especially useful for running Kubernetes inside Rootless Docker/Podman with kind or minikube. (#92863, @AkihiroSuda) [SIG Network, Node and Testing]

Introduce a feature gate DisableCloudProviders allowing to disable cloud-provider initialization in KAPI, KCM and kubelet. DisableCloudProviders FeatureGate is currently in Alpha, which means is currently disabled by default. Once the FeatureGate moves to beta, in-tree cloud providers would be disabled by default, and a user won't be able to specify --cloud-provider=<aws|openstack|azure|gcp|vsphere> anymore to any of KCM, KAPI or kubelet. Only a '--cloud-provider=external' would be allowed. CCM would have to run out-of-tree with CSI. (#100136, @Danil-Grigorev)

This allows the user to specify the image pull policy during "kubeadm init" and "kubeadm join". The value of this field must be one of Always, IfNotPresent or Never. The default behavior continues to be IfNotPresent. (#102901, @wangyysde)

Services with externalTrafficPolicy: Local now support graceful termination when using the iptables or ipvs mode of kube-proxy with EndpointSlices enabled. Specifically, if a connection for such a service arrives on a node when there are no "Ready" endpoints for the service, but there is at least one Terminating pod for that service on the node, then kube-proxy will send the traffic to the Terminating pod rather than dropping it. This patches up a race condition between when a pod is killed and when the external load balancer notices that it has been killed. (#97238, @andrewsykim)
Shell completion has been migrated to Cobra's go solution. kubectl is now smarter about disabling file completion when it does not apply. Furthermore, completion for the cp command does not show all files unless the user has started typing something. (#96087, @marckhouzam) [SIG CLI]
Some of the in-tree storage drivers indicate support for the MetricsProvider interface, but fail to configure this for BlockMode volumes. With a recent change, Kubelet will call GetMetrics() for BlockMode volumes, and the in-tree drivers that miss the support cause a Go panic.

The system:aggregate-to-edit role no longer includes write access to the Endpoints API. For new Kubernetes 1.22 clusters, the edit and admin roles will no longer include that access in newly created Kubernetes 1.22 clusters. This will have no affect on existing clusters upgrading to Kubernetes 1.22. To retain write access to Endpoints in the aggregated edit and admin roles for newly created 1.22 clusters, refer to https://github.com/kubernetes/website/pull/29025. (#103704, @robscott) [SIG Auth and Network]
The conformance tests:
- Services should serve multiport endpoints from pods
- Services should serve a basic endpoint from pods were only validating the API objects, not performing any validation on the actual Services implementation. Those tests now validate that the Services under test are able to forward traffic to the endpoints. (#101709, @aojea) [SIG Network and Testing]
The current behavior for Services that IPFamilyPolicy set as PreferDualstack. The current behavior when the cluster is upgraded to dual-stack is:
- Services that have been set to IPFamilyPolicy = PreferDualstack will be upgraded when the service object is updated. e.g., when a user change a label.
This behavior will change to:
- Services that have been set IPFamilyPolicy = PreferDualstack will not be upgraded when the service object is updated. User can still change policy, type etc and existing behaviors remain the same. (#102898, @khenidak) [SIG Network and Testing]

Changelog since v1.22.0-beta.2

Changes by Kind

API Change

Revert addition of Add PersistentVolumeClaimDeletePoilcy to StatefulSet API. (#103747, @mattcary) [SIG API Machinery and Apps]

Bug or Regression

Aggregated roles no longer include write access to EndpointSlices. This rolls back part of a change that was introduced earlier in the Kubernetes 1.22 cycle. (#103703, @robscott) [SIG Auth and Network]
Fix winkernel kube-proxy to only use dual stack when host and networking supports it (#101047, @jsturtevant) [SIG Network and Windows]
The system:aggregate-to-edit role no longer includes write access to the Endpoints API. For new Kubernetes 1.22 clusters, the edit and admin roles will no longer include that access in newly created Kubernetes 1.22 clusters. This will have no affect on existing clusters upgrading to Kubernetes 1.22. To retain write access to Endpoints in the aggregated edit and admin roles for newly created 1.22 clusters, refer to https://github.com/kubernetes/website/pull/29025. (#103704, @robscott) [SIG Auth and Network]
The reason and message fields for pod status are no longer reset unless the phase also changes. (#103785, @smarterclayton) [SIG Node]

Changelog since v1.22.0-beta.1

Changes by Kind

API Change

Added field .status.uncountedTerminatedPods to the Job resource. This field is used by the job controller to keep track of finished pods before adding them to the Job status counters.

Pods created by the job controller get the finalizer batch.kubernetes.io/job-tracking

Jobs that are tracked using this mechanism get the annotation batch.kubernetes.io/job-tracking. This is a temporary measure. Two releases after this feature graduates to beta, the annotation won't be added to Jobs anymore. (#98817, @alculquicondor) [SIG API Machinery, Apps, Auth and CLI]
Ephemeral containers are now allowed to configure a securityContext that differs from that of the Pod.

Cluster administrators should ensure that security policy controllers support EphemeralContainers before enabling this feature in clusters. (#99023, @verb) [SIG API Machinery, Apps, Auth and Node]
If someone had the ProbeTerminationGracePeriod alpha feature enabled in 1.21, they should update/delete any workloads/pods with probe terminationGracePeriods < 1 before upgrading (#103245, @wzshiming) [SIG Apps and Node]
Introducing Memory QoS support with cgroups v2 (Alpha) The MemoryQoS feature is now in Alpha. This allows kubelet running with cgroups v2 to set memory QoS at container, pod and QoS level to protect and guarantee better memory quality. This feature can be enabled through feature gate MemoryQoS. (#102970, @borgerli) [SIG Node and Storage]
NodeSwapEnabled feature flag was renamed to NodeSwap

The flag was only available in the 1.22.0-beta.1 release, and the new flag should be used going forward. (#103553, @ehashman) [SIG Node]
Removed the feature flag for probe-level termination grace period from Kubelet. If a user wants to disable this feature on already created pods, they will have to delete and recreate the pods. (#103168, @raisaat) [SIG Apps and Node]
Track Job completion through status and Pod finalizers, removing dependency on Pod tombstones. (#98238, @alculquicondor) [SIG API Machinery, Apps, Auth and Testing]
When using kubectl replace (or the equivalent API call) on a Service, the caller no longer needs to do a read-modify-write cycle to fetch the allocated values for .spec.clusterIP and .spec.ports[].nodePort. Instead the API server will automatically carry these forward from the original object when the new object does not specify them. (#103532, @thockin) [SIG Apps and Network]

Feature

APIServerTracing now collects spans from etcd client calls, and propagates context to etcd. (#103216, @dashpole) [SIG API Machinery, Cloud Provider and Instrumentation]
APIServerTracing now collects spans from outgoing requests to admission webhooks. (#103601, @dashpole) [SIG API Machinery]
Kubernetes is now built with Golang 1.16.6 (#103669, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]
Leader Migration for controller managers graduated to beta. (#103533, @jiahuif) [SIG API Machinery and Cloud Provider]
Promote EndpointSliceTerminatingCondition to Beta. This enables the 'terminating' and 'serving' conditions for EndpointSlice by default. (#103596, @andrewsykim) [SIG Network and Testing]

Bug or Regression

Fix "verb" and "scope" tag in apiserver_longrunning_gauge and apiserver_request_terminations_total such that a GET namespaced object by name call will have verb "GET" instead of "LIST", and scope "resource" instead of "namespace" (#103565, @zhan849) [SIG API Machinery and Instrumentation]
Fix a number of race conditions in the kubelet when pods are starting up or shutting down that might cause pods to take a long time to shut down. (#102344, @smarterclayton) [SIG Apps, Node, Storage and Testing]
Fix the code is leaking the defaulting between unrelated pod instances. (#103284, @kebe7jun) [SIG CLI]
Fix: return empty VMAS name if using standalone VM (#103470, @nilo19) [SIG Cloud Provider]
GCE Windows clusters have their TCP/IP parameters are set to GCE's recommended values. (#103057, @jeremyje) [SIG Cloud Provider and Windows]
Graceful termination will now be honored when deleting a collection of pods. (#100101, @deads2k) [SIG API Machinery, Node and Testing]
YAML documents separators ("---") can now be followed by whitespace and comments ("# ....") on the same line. This fixes a bug where documents starting with a comment after the separator were ignored. Other types of content on the same line will result in an error. (#103457, @codearky) [SIG API Machinery]
oc describe quota used has the same unit format as hard (#102177, @atiratree) [SIG CLI]

Changelog since v1.22.0-beta.0

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

The flag --experimental-patches is now deprecated and will be removed in a future release. You can migrate to using the new flag --patches. Add a new field {Init|Join}Configuration.patches.directory that can be used for the same purpose. For "init" and "join" it is now recommended that you migrate to configure patches via {Init|Join}Configuration.patches.directory. For the time being, these flags can be mixed with --config, but that might change in the future. On a command line, the last *patches flag takes precedence over previous flags and the value in config. "kubeadm upgrade" --patches will continue to be the only available option, since "upgrade" does not support a configuration file yet. (#103063, @neolit123) [SIG Cluster Lifecycle]

Changes by Kind

Deprecation

The feature Dynamic Kubelet Configuration is deprecated and kubelet will report warning when the flag --dynamic-config-dir is used. Feature gate DynamicKubeletConfig is disabled out of the box and needs to be explicitly enabled. (#102966, @SergeyKanzhelev) [SIG Cloud Provider, Instrumentation and Node]
The in-tree azure and gcp auth plugins have been deprecated. The https://github.com/Azure/kubelogin and gcloud commands serve as out-of-tree replacements via the kubectl/client-go credential plugin mechanism. (#102181, @enj) [SIG API Machinery and Auth]

API Change

A new score extension for NodeResourcesFit plugin that merges the functionality of NodeResourcesLeastAllocated,NodeResourcesMostAllocated,RequestedToCapacityRatio plugins, which are marked as deprecated as of v1beta2. In v1beta1, the three plugins can still be used in v1beta1 but not at the same time with the score extension of NodeResourcesFit

--> ([#101822](https://github.com/kubernetes/kubernetes/pull/101822), [@yuzhiquan](https://github.com/yuzhiquan)) [SIG API Machinery, Apps, Auth, Cloud Provider, Instrumentation, Node, Scheduling, Storage and Testing]

Add DataSourceRef alpha field to PVC spec, which allows contents other than PVCs and VolumeSnapshots to be data sources. (#103276, @bswartz) [SIG API Machinery, Apps and Storage]
Add PersistentVolumeClaimDeletePoilcy to StatefulSet API. (#99378, @mattcary) [SIG API Machinery and Apps]
Add distributed tracing to the kube-apiserver. It is can be enabled with the feature gate: APIServerTracing=true (#94942, @dashpole) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node, Storage and Testing]
Added new kubelet alpha feature SeccompDefault. This feature enables falling back to the RuntimeDefault (former runtime/default) seccomp profile if nothing else is specified in the pod/container SecurityContext or the pod annotation level. To use the feature, enable the feature gate as well as set the kubelet configuration option SeccompDefault (--seccomp-default) to true. (#101943, @saschagrunert) [SIG Node]
Adds the ReadWriteOncePod access mode for PersistentVolumes and PersistentVolumeClaims. Restricts volume access to a single pod on a single node. (#102028, @chrishenzie) [SIG Apps, CLI, Node, Scheduling and Storage]
Alpha swap support can now be enabled on Kubernetes nodes with the NodeSwapEnabled feature flag. See for details. (#102823, @ehashman) [SIG Node]
CSIServiceAccountToken is GA. (#103001, @zshihang) [SIG Auth and Storage]
Enforce the ReadWriteOncePod PVC access mode during scheduling (#103082, @chrishenzie) [SIG Apps, CLI, Node, Scheduling and Storage]
Improved parsing of label selectors (#102188, @alculquicondor) [SIG API Machinery]
Kube API server accepts Impersonate-Uid header to impersonate a user with a specific UID, in the same way that you can currently use Impersonate-User, Impersonate-Group and Impersonate-Extra (#99961, @margocrawf) [SIG API Machinery, Auth and Testing]
Kube-scheduler: a plugin enabled in a v1beta2 configuration file takes precedence over the default configuration for that plugin; this simplifies enabling default plugins with custom configuration without needing to explicitly disable those default plugins. (#99582, @chendave) [SIG Scheduling]
Scheduler could be configured to consider new resources beside CPU and memory, GPU for example, for the score plugin of NodeResourcesBalancedAllocation. (#101946, @chendave) [SIG Scheduling]
Suspend Job feature graduated to beta Added the "action" label to Job controller sync metrics job_sync_total and job_sync_duration_seconds (#102022, @adtac) [SIG Apps, Instrumentation and Testing]
TerminationGracePeriodSeconds on pod specs and container probes should not be negative. Negative values of TerminationGracePeriodSeconds will be treated as the value 1s on the delete path. Immutable field validation will be relaxed in order to update negative values. In a future release, negative values will not be permitted. (#98866, @wzshiming) [SIG API Machinery, Apps and Node]
The API documentation for the DaemonSet's spec.updateStrategy.rollingUpdate.maxUnavailable field was corrected to state that the value is rounded up. (#101296, @Miciah) [SIG Apps and CLI]
The CertificateSigningRequest.certificates.k8s.io API supports an optional expirationSeconds field to allow the client to request a particular duration for the issued certificate. The default signer implementations provided by the Kubernetes controller manager will honor this field as long as it does not exceed the --cluster-signing-duration flag. (#99494, @enj) [SIG API Machinery, Apps, Auth, CLI, Instrumentation, Node, Security and Testing]
The ServiceAppProtocol feature gate has been removed. It reached GA in Kubernetes 1.20. (#103190, @robscott) [SIG Network]

Feature

(alpha feature) If the CSI driver supports the NodeServiceCapability VOLUME_MOUNT_GROUP and the DelegateFSGroupToCSIDriver feature gate is enabled, kubelet will delegate applying FSGroup to the driver by passing it to NodeStageVolume and NodePublishVolume, regardless of what other FSGroup policies are set. (#103244, @verult) [SIG Apps and Storage]
API Server tracing can now trace re-entrant api requests. (#103218, @dashpole) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]
Add unified map on CRI to support cgroup v2. Refer to https://github.com/opencontainers/runtime-spec/blob/master/config-linux.md#unified. (#102578, @payall4u) [SIG Node]
Added field-selector option for kubectl top pod (#102155, @lauchokyip) [SIG CLI]
Added new metrics about API Priority and Fairness. Each one has a label priority_level. The last two also have a label bound taking values min and `max.
- apiserver_flowcontrol_current_r: R(the time of the last change in state of the queues)
- apiserver_flowcontrol_dispatch_r: R(the time of the latest request dispatch)
- apiserver_flowcontrol_latest_s: S(the request last dispatched) = R(when that request starts executing in the virtual world)
- apiserver_flowcontrol_next_s_bounds: min and max next S among non-empty queues
- apiserver_flowcontrol_next_discounted_s_bounds: min and max next S - (sum [over requests executing] width * estimatedDuration) among non-empty queues (#102859, @MikeSpreitzer) [SIG API Machinery and Instrumentation]
Adding --restart-kubelet flag on E2E Node test suite (#97028, @knabben) [SIG Node and Testing]
Adds feature gate KubeletInUserNamespace which enables support for running kubelet in a user namespace.

The user namespace has to be created before running kubelet. All the node components such as CRI need to be running in the same user namespace.

When the feature gate is enabled, kubelet ignores errors that happens during setting the following sysctl values: vm.overcommit_memory, vm.panic_on_oom, kernel.panic, kernel.panic_on_oops, kernel.keys.root_maxkeys, kernel.keys.root_maxbytes. (These sysctl values for the host, not for the containers)

kubelet also ignores an error during opening /dev/kmsg. This feature gate also allows kube-proxy to ignore an error during setting RLIMIT_NOFILE.

This feature gate is especially useful for running Kubernetes inside Rootless Docker/Podman with kind or minikube. (#92863, @AkihiroSuda) [SIG Network, Node and Testing]
Adds metrics for the delegated authenticator used by extension APIs that delegate authentication logic to the Kube API server. (#99364, @p0lyn0mial) [SIG API Machinery, Auth, Instrumentation and Node]
Adds metrics for the delegated authorizer used by extension APIs that delegate authorization logic to the Kube API server. (#100339, @p0lyn0mial) [SIG API Machinery, Auth, Instrumentation and Node]
Client-go credential plugins are now GA (#102890, @ankeesler) [SIG API Machinery, Auth and Testing]
Deprecated warning message for igonre-errors flag. (#102677, @yuzhiquan) [SIG CLI]
Endpoints that have more than 1000 endpoints will be truncated and the endpoints.kubernetes.io/over-capacity annotation on the Endpoints resource will be set to truncated. (#103520, @swetharepakula) [SIG Apps and Network]
Expose /debug/flags/v to allow dynamically setting log level for kube-proxy. (#98306, @borgerli) [SIG Network]
Expose container start time as container_start_time_seconds in kubelet /metrics/resource endpoint (#102444, @sanwishe) [SIG Instrumentation, Node and Testing]
Extended resources defined in LeastAllocated, MostAllocated and RequestedToCapacityRatio plugin argument are bypassed by the scheduler if the incoming Pod doesn't request them in the pod spec. (#103169, @Huang-Wei) [SIG Scheduling]
Features gates EndpointSliceProxying & WindowsEndpointSliceProxying are now GA and cannot be disabled. Kube-proxy will use EndpointSlices for endpoint information. (#103451, @swetharepakula) [SIG Network]
IngressClassNamespacedParams feature gate has graduated to beta and is enabled by default. This means IngressClass resource will now have two new fields - spec.paramters.namespace and spec.parameters.scope. (#101711, @hbagdi) [SIG Network]
JSON logging format is no longer available by default in non-core Kubernetes Components and require owners to opt in. (#102869, @mengjiao-liu) [SIG API Machinery, Cluster Lifecycle and Instrumentation]
Kube-apiserver: the alpha PodSecurity feature can be enabled by passing --feature-gates=PodSecurity=true, and enables controlling allowed pods using namespace labels. See https://git.k8s.io/enhancements/keps/sig-auth/2579-psp-replacement for more details. (#103099, @liggitt) [SIG API Machinery, Auth, Instrumentation, Release, Security and Testing]
Kube-proxy uses V1 EndpointSlices. (#103306, @swetharepakula) [SIG Network]
LogarithmicScaleDown is now Beta and enabled by default (#101767, @damemi) [SIG Apps and Instrumentation]
Make kubectl command headers default for beta. (#103238, @seans3) [SIG CLI]
Mark net.ipv4.ip_unprivileged_port_start as safe sysctl (#103326, @pacoxu) [SIG Auth, Network, Node and Security]
Move the memory manager feature to the beta that will make it enabled by default with the None policy. (#101947, @cynepco3hahue) [SIG Node and Testing]
Promote the ServiceInternalTrafficPolicy feature to beta, which enables the internalTrafficPolicy field of Service by default. (#103462, @andrewsykim) [SIG Apps and Network]
Promote the feature ServiceLBNodePortControl to Beta (#100412, @hanlins) [SIG API Machinery, Apps, Architecture, Network and Testing]
Scheduler nows provides an option for plugin developers to move Pods to activeQ proactively. (#103383, @Huang-Wei) [SIG Scheduling and Testing]
Services with externalTrafficPolicy: Local now support graceful termination when using the iptables or ipvs mode of kube-proxy with EndpointSlices enabled. Specifically, if a connection for such a service arrives on a node when there are no "Ready" endpoints for the service, but there is at least one Terminating pod for that service on the node, then kube-proxy will send the traffic to the Terminating pod rather than dropping it. This patches up a race condition between when a pod is killed and when the external load balancer notices that it has been killed. (#97238, @andrewsykim) [SIG Network, Scalability and Windows]
Shell completion has been migrated to Cobra's go solution. kubectl is now smarter about disabling file completion when it does not apply. Furthermore, completion for the cp command does not show all files unless the user has started typing something. (#96087, @marckhouzam) [SIG CLI]
The HugePageStorageMediumSize feature has been promoted to GA, allowing unconditional usage of multiple sizes huge page resources on a container level. (#99144, @bart0sh) [SIG Apps, Node and Storage]
Update the system-validators library to v1.5.0. Includes validation for seccomp and fixes a stdout/stderr problem in the Docker validator. (#103390, @ironyman) [SIG Cluster Lifecycle]
Updates the following images to pick up CVE fixes:
- debian to v1.8.0
- debian-iptables to v1.6.5
- setcap to v2.0.3 (#103235, @thejoycekung) [SIG API Machinery, Release and Testing]
kubectl debug is able to create ephemeral containers in pre-1.22 clusters with the EphemeralContainers feature enabled. Note that versions of kubectl prior to 1.22 are unable to create ephemeral containers in clusters version 1.22 and greater due to an API change. (#103292, @verb) [SIG CLI]

Documentation

kubectl debug will now print a warning message when using the --target option since many container runtimes do not support this yet. (#101074, @verb) [SIG CLI]

Kubelet: the returned value for PodIPs is the same in the Downward API and in the pod.status.PodIPs field (#103307, @aojea) [SIG Network and Node]
Metrics Server will use Addon Manager 1.8.3 (#103541, @jbartosik) [SIG Cloud Provider and Instrumentation]
Pods that are known to the kubelet to have previously been Running should not revert to Pending state; the kubelet will now infer a termination. (#102821, @ehashman) [SIG Node]
Switch scheduler to generate the merge patch on pod status instead of the full pod (#103133, @marwanad) [SIG Scheduling]
The current behavior for Services that IPFamilyPolicy set as PreferDualstack. The current behavior when the cluster is upgraded to dual-stack is:
- Services that have been set to IPFamilyPolicy = PreferDualstack will be upgraded when the service object is updated. e.g., when a user change a label.
This behavior will change to:
- Services that have been set IPFamilyPolicy = PreferDualstack will not be upgraded when the service object is updated. User can still change policy, type etc and existing behaviors remain the same. (#102898, @khenidak) [SIG Network and Testing]

Changelog since v1.22.0-alpha.3

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

Kubeadm: the flag --cri-socket is no longer allowed in a mixture with the flag --config. Please use the kubeadm configuration for setting the CRI socket for a node using {Init|Join}Configuration.nodeRegistration.criSocket. (#101600, @KofClubs) [SIG Cluster Lifecycle]

Changes by Kind

Deprecation

Deprecate --record flag in kubectl. The --record flag is being replaced with the mechanism from https://github.com/kubernetes/enhancements/tree/master/keps/sig-cli/859-kubectl-headers which annotates HTTP requests with kubectl command details. (#102873, @soltysh) [SIG CLI]
E2e.test: removed the --viper-config flag. If you were previously using this to pass flags to e2e.test via a file, you will need to pass them directly on the command line, e.g. e2e.test --e2e-output-dir (#102598, @dims) [SIG Testing]
Newly provisioned PVs by vSphere in-tree plugin will no longer have the beta FailureDomain label. vSphere volume plugin will start to have GA topology label instead. (#102414, @divyenpatel) [SIG Cloud Provider, Storage and Testing]
The deprecated flag --hard-pod-affinity-symmetric-weight and --scheduler-name have been removed from kube-scheduler. Use ComponentConfig instead to configure those parameters. (#102805, @ahg-g) [SIG Scheduling]

API Change

Because of the implementation logic of time.Format in golang, the displayed time zone is not consistent (#102366, @cndoit18) [SIG Apps, Auth, Autoscaling, CLI, Cluster Lifecycle, Instrumentation, Network, Node and Testing]
Endpoint slices mirroring controller no longer mirrors the last-applied-configuration annotation created by kubectl to updated endpoint slices (#102731, @sharmarajdaksh) [SIG API Machinery, Apps, Cloud Provider, Network, Release, Scheduling, Storage and Testing]
Exec plugin authors can override default handling of standard input via new interactiveMode kubeconfig field (#99310, @ankeesler) [SIG API Machinery, Auth, CLI and Testing]
Kube-scheduler component config v1beta2 API available Three scheduler plugins deprecated (NodeLabel, ServiceAffinity, NodePreferAvoidPods) (#99597, @adtac) [SIG Scheduling]
Network Policy EndPort is graduated to beta and is enabled by default (#102834, @rikatz) [SIG Network]

Feature

A new metric apiserver_flowcontrol_request_concurrency_in_use that shows the number of seats (concurrency) occupied by the currently executing requests in the API Priority and Fairness system (#102795, @tkashem) [SIG API Machinery and Instrumentation]
Add a namespace label for all apiserver_admission_* metrics.
- Expand the histogram range to 0-10s for all apiserver_admission_*_duration_seconds metrics. (#101208, @voutcn) [SIG API Machinery and Instrumentation]
Add unified map on CRI to support cgroup v2. Refer to https://github.com/opencontainers/runtime-spec/blob/master/config-linux.md#unified. (#102578, @payall4u) [SIG Node]
Base-images: Update to debian-base:buster-v1.7.1 (#102594, @mengjiao-liu) [SIG API Machinery and Release]
Implement minReadySeconds for the StatefulSets. (#101316, @ravisantoshgudimetla) [SIG Apps and Testing]
Kubeadm: add the "--dry-run" flag to the "control-plane" phase of "kubeadm init" (#102722, @vinayakankugoyal) [SIG Cluster Lifecycle]
Kubeadm: add the "imagePullPolicy" field in the "nodeRegistration" section of InitConfiguration and JoinConfiguration in v1beta3. This allows the user to specify the image pull policy during "kubeadm init" and "kubeadm join". The value of this field must be one of "Always", "IfNotPresent" or "Never". The default behavior continues to be "IfNotPresent". (#102901, @wangyysde) [SIG Cluster Lifecycle]
Kubeadm: update CoreDNS to 1.8.4. Grant CoreDNS permissions to "list" and "watch" EndpointSlice objects to accommodate dual-stack support. (#102466, @pacoxu) [SIG Cluster Lifecycle]
Kubernetes is now built with Golang 1.16.5 (#102689, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]
Leader Migration now support a wildcard component name and the default value. (#102711, @jiahuif) [SIG API Machinery and Cloud Provider]
SetHostnameAsFQDN has been graduated to GA, which means feature cannot be disabled using a feature gate. (#101294, @javidiaz) [SIG Node]
The pod resource API will provide memory manager metrics in the case when the memory manager feature gate enabled and the memory manager policy is static. (#101030, @cynepco3hahue) [SIG Node and Testing]
Update etcd version to 3.5.0-beta.3 (#102062, @serathius) [SIG API Machinery, Cloud Provider, Cluster Lifecycle and Testing]

Bug or Regression

After DBus restarts, make GracefulNodeShutdown work again (#100369, @wzshiming) [SIG Node and Testing]
Aggregate write permissions on events to edit and admin role (#102858, @tumido) [SIG Auth]
Changed the Graceful Node Shutdown Pod termination reason and message. Changed the Graceful Node Shutdown Pod rejection reason and message. (#102840, @Kissy) [SIG Node]
Fix a bug on the endpoint slices mirroring controller where endpoint NotReadyAddresses were mirrored as Ready to the corresponding EndpointSlice (#102683, @aojea) [SIG Apps and Network]
Fix scoring for NodeResourcesMostAllocated and NodeResourcesBalancedAllocation plugins when nodes have containers with no requests. This was leaving to under-utilization of small nodes. (#102925, @alculquicondor) [SIG Scheduling]
Fix: cleanup outdated routes (#102935, @nilo19) [SIG Cloud Provider]
Fixed a bug that scheduler extenders are not called on preemptions (#103019, @ordovicia) [SIG Scheduling]
Fixed an issue with kubectl on certain older version of Windows or when legacy console mode is enabled on Windows 8 which causes kubectl exec to crash (#102825, @n4j) [SIG API Machinery, CLI, Cloud Provider and Cluster Lifecycle]
Fixed starting new pods after previous pod timed out unmounting its volumes. (#100183, @jsafrane) [SIG Node, Storage and Testing]
Fixes a bug due to which the controller was not populating the lastSuccessfulTime field added to batch/v1 cronjob.status (#102642, @alaypatel07) [SIG Apps]
Kube-apiserver now reports the synthetic verb when logging requests, better explaining the user intent and matching what is reported in the metrics. (#102934, @lavalamp) [SIG API Machinery and Instrumentation]
Kubeadm: allow passing the flag --log-file if --config is passed. If you wish to log to a file you must also pass --logtostderr=false or --alsologtostderr=true. Alternatively you can pipe to a file using "kubeadm ... | tee ...". (#101449, @CaoDonghui123) [SIG Cluster Lifecycle]
Kubeadm: remove the "ephemeral_storage" request from the etcd static pod that kubeadm deploys on stacked etcd control plane nodes. This request has caused sporadic failures on some setups due to a problem in the kubelet with cadvisor and the LocalStorageCapacityIsolation feature gate. See this issue for more details: https://github.com/kubernetes/kubernetes/issues/99305 (#102673, @jackfrancis) [SIG Cluster Lifecycle]
Updates hostprocess tests to specify user (#102965, @jsturtevant) [SIG Testing and Windows]
VSphere: Fix regression during attach disk if datastore is within a storage folder or datastore cluster. (#102892, @gnufied) [SIG Cloud Provider and Storage]

Other (Cleanup or Flake)

Allow CSI drivers to just run offline expansion tests (#102665, @gnufied) [SIG Storage and Testing]
Client-go: reduce verbosity of "Starting/Stopping reflector" messages to 3 again (#102788, @pohly) [SIG API Machinery]
JSON logging now supports having information about source code location in the logging format, source code information is available under the key "caller" (#102437, @MadhavJivrajani) [SIG API Machinery, Cluster Lifecycle and Instrumentation]
Migrate staging/src/k8s.io/apiserver/pkg/registry logs to structured logging. (#98287, @lala123912) [SIG API Machinery]
Remove balanced attached node volumes feature (#102443, @ravisantoshgudimetla) [SIG Scheduling]
The etcd client has been updated to 3.5.0; github.com/golang/protobuf, google.golang.org/protobuf, and google.golang.org/grpc have been updated to current versions. (#100488, @liggitt) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node, Storage and Testing]
Update Azure Go SDK to v55.0.0 (#102441, @feiskyer) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]
Update Calico to v3.19.1 (#102386, @JornShen) [SIG Cloud Provider]
Update dep google/gnostic and google/go-cmp to v0.5.5 and updating transitive dependencies protobuf (#102783, @mcbenjemaa) [SIG Architecture and Testing]

Changelog since v1.22.0-alpha.2

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

CSI migration of AWS EBS volumes requires AWS EBS CSI driver ver. 1.0 that supports allowAutoIOPSPerGBIncrease parameter in StorageClass. (#101082, @jsafrane) [SIG Storage]
Conformance image is now built with Distroless. Users running Conformance testing should rely on container entrypoint instead of manual invocation to /run_e2e.sh or /gorunner, as they are now deprecated and will be removed in 1.25 release. Invoking ginkgo and e2e.test are still supported through overriding entrypoint (docker) or defining container spec.command (kubernetes) (#99178, @wilsonehusin) [SIG Release and Testing]
Default StreamingProxyRedirects to disabled. If there is a >= 2 version skew between master and nodes, and the old nodes were enabling --redirect-container-streaming, this will break them. In this case, the StreamingProxyRedirects can still be manually enabled. (#101647, @pacoxu) [SIG API Machinery and Node]
Kubeadm: remove the automatic detection and matching of cgroup drivers for Docker. For new clusters if you have not configured the cgroup driver explicitly you might get a failure in the kubelet on driver mismatch (kubeadm clusters should be using the "systemd" driver). Also remove the "IsDockerSystemdCheck" preflight check (warning) that checks if the Docker cgroup driver is set to "systemd". Ideally such detection / coordination should be on the side of CRI implementers and the kubelet (tracked here https://github.com/kubernetes/kubernetes/issues/99808). Please see the following page on how to configure cgroup drivers with kubeadm manually: https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/configure-cgroup-driver/ (#99647, @neolit123) [SIG Cluster Lifecycle]
The CSIMigrationVSphereComplete feature flag is removed. InTreePluginvSphereUnregister will be the way moving forward. (#101272, @Jiawei0227) [SIG API Machinery, Node and Storage]

Changes by Kind

Deprecation

E2e.test: removed the --viper-config flag. If you were previously using this to pass flags to e2e.test via a file, you will need to pass them directly on the command line, e.g. e2e.test --e2e-output-dir (#102598, @dims) [SIG Testing]
Remove support for the Service topologyKeys field (alpha) and the kube-proxy implementation of it. This field was deprecated several cycles ago. This functionality is replaced by the combination of automatic topology hints per-endpoint (alpha) and the Service internalTrafficPolicy field (alpha). (#102412, @andrewsykim) [SIG API Machinery, Apps and Network]

API Change

--ssh-user and --ssh-key options are removed. They only functioned on GCE, and only in-tree. Use the apiserver network proxy instead. (#102297, @deads2k) [SIG API Machinery, Cloud Provider and Testing]
Enable MaxSurge for DS by default (#101742, @ravisantoshgudimetla) [SIG Apps and Testing]
Introduce minReadySeconds api to the StatefulSets. (#100842, @ravisantoshgudimetla) [SIG API Machinery, Apps and Testing]
Kube-controller-manger: the --horizontal-pod-autoscaler-use-rest-clients flag and Heapster support in the horizontal pod autoscaler, deprecated since 1.12, is removed. (#90368, @serathius) [SIG API Machinery, Apps, Autoscaling, Cloud Provider and Instrumentation]
The deprecated flag --algorithm-provider has been removed from kube-scheduler. Use instead ComponentConfig to configure the set of enabled plugins (#102239, @Haleygo) [SIG Cloud Provider and Scheduling]

Feature

An audit log entry will be generated when a validating admission webhook is failing open. (#92739, @cnphil) [SIG API Machinery]
BoundServiceAccountTokenVolume is GA. The feature gate is going to be removed in 1.23. (#101992, @zshihang) [SIG Auth, Cloud Provider and Testing]
Graduate prefer nominated node to beta (#102201, @chendave) [SIG Scheduling]
Introduce a feature gate DisableCloudProviders allowing to disable cloud-provider initialization in KAPI, KCM and kubelet.

DisableCloudProviders FeatureGate is currently in Alpha, which means is currently disabled by default. Once the FeatureGate moves to beta, in-tree cloud providers would be disabled by default, and a user won't be able to specify --cloud-provider=<aws|openstack|azure|gcp|vsphere> anymore to any of KCM, KAPI or kubelet. Only a --cloud-provider=external would be allowed. CCM would have to run out-of-tree with CSI. (#100136, @Danil-Grigorev) [SIG API Machinery, Cloud Provider, Instrumentation and Node]
Kubeadm: add a new field "skipPhases" to v1beta3 InitConfiguration and JoinConfiguration that can contain a list of phases to skip during "kubeadm init" and "kubeadm join". The flag "--skip-phases" takes precedence over this field. (#101923, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: add the RootlessControlPlane kubeadm specific feature gate (Alpha in 1.22, disabled by default). It can be used to enable an experimental feature that makes the control plane component static Pod containers for kube-apiserver, kube-controller-manager, kube-scheduler and etcd to run as a non-root users. (#102158, @vinayakankugoyal) [SIG Cluster Lifecycle]
Kubeadm: during "kubeadm init/join/upgrade", always default the "cgroupDriver" value in the KubeletConfiguration to "systemd", unless the user was explicit about the value. See https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/configure-cgroup-driver/ for more details. (#102133, @pacoxu) [SIG Cluster Lifecycle]
Kubectl: add "LAST RESTART" column to "kubectl get pods" output (#100142, @Ethyling) [SIG CLI]
NetworkPolicy validation framework support for windows (#98077, @jayunit100) [SIG Auth, Network and Testing]
New feature gate "ExpandedDNSConfig" is now available. This feature allows Kubernetes to have expanded DNS configuration. (#100651, @gjkim42) [SIG Apps, Network and Node]
Promote CronJobControllerV2 flag to GA, with removal in 1.23 (#102529, @soltysh) [SIG Apps]
Promote Cronjobs storage version to batch/v1 (#102363, @mengjiao-liu) [SIG API Machinery and Testing]
Scheduler now registers event handlers dynamically. (#101394, @Huang-Wei) [SIG Scheduling and Testing]
Some of the in-tree storage drivers indicate support for the MetricsProvider interface, but fail to configure this for BlockMode volumes. With a recent change, Kubelet will call GetMetrics() for BlockMode volumes, and the in-tree drivers that miss the support cause a Go panic. Now the in-tree storage drivers that support BlockMode volumes, will return the Capacity of the volume in the GetMetrics() call. (#101587, @nixpanic) [SIG Instrumentation, Node, Storage and Testing]
Support FakeClientset match subresource (#100939, @wzshiming) [SIG API Machinery and Testing]
Update the Debian images to pick up CVE fixes in the base images:
- Update the debian-base image to v1.7.0
- Update the debian-iptables image to v1.6.1 (#102302, @xmudrii) [SIG API Machinery, Release and Testing]
Update the setcap image to buster-v2.0.1 (#102377, @xmudrii) [SIG Release]
Watch requests are now handled throttled by priority and fairness filter in kube-apiserver (#102171, @wojtek-t) [SIG API Machinery]
[kubectl] Enable using protocol buffers to request Metrics API (#102039, @serathius) [SIG CLI]

Bug or Regression

Aggregate errors when putting vmss (#98350, @nilo19) [SIG Cloud Provider]
Fix a bug on the endpoint slices mirroring controller where endpoint NotReadyAddresses were mirrored as Ready to the corresponding EndpointSlice (#102683, @aojea) [SIG Apps and Network]
Fix a bug that a preemptor pod may exist as a phantom in the scheduler. (#102498, @Huang-Wei) [SIG Scheduling]
Fix nulls are handles of array's and objects in json patches. (#102467, @pacoxu) [SIG API Machinery, Apps, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Storage and Testing]
Fix resource enforcement when using systemd cgroup driver (#102147, @kolyshkin) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node, Storage and Testing]
Fix runtime container status for post start hook error (#100608, @pacoxu) [SIG Node]
Fixed an issue blocking azure auth to prompt to device code authentication flow when refresh token expires. (#102063, @tdihp) [SIG API Machinery and Auth]
Fixed garbage collection of dangling VolumeAttachments for PersistentVolumes migrated to CSI on startup of kube-controller-manager. (#102176, @timebertt) [SIG Apps and Storage]
Fixed kubelet runtime panic for timed-out portforward streams. (#102489, @saschagrunert) [SIG API Machinery and Node]
Fixed very rare volume corruption when a pod is deleted while kubelet is offline. (#102059, @jsafrane) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Storage]
Fixes issue with websocket-based watches of Service objects not closing correctly on timeout (#102539, @liggitt) [SIG API Machinery and Testing]
Kubeadm: when using a custom image repository for CoreDNS kubeadm now will append the "coredns" image name instead of "coredns/coredns", thus restoring the behaviour existing before the v1.21 release. Users who rely on nested folder for the coredns image should set the "clusterConfiguration.dns.imageRepository" value including the nested path name (e.g using "registry.company.xyz/coredns" will force kubeadm to use "registry.company.xyz/coredns/coredns" image). No action is needed if using the default registry (k8s.gcr.io). (#102502, @ykakarap) [SIG Cluster Lifecycle]
Retry FibreChannel devices cleanup after error to ensure FC device is detached before it can be used on another node. (#101862, @jsafrane) [SIG Storage]
ServiceOwnsFrontendIP shouldn't report error when the public IP doesn't match (#102516, @nilo19) [SIG Cloud Provider]
Support correct sorting for cpu, memory, storage, ephemeral-storage, hugepages, and attachable-volumes (#100435, @lauchokyip) [SIG CLI and Testing]
Update klog v2.9.0 (#102332, @pacoxu) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Storage]
Update kube-proxy base image debian-iptables to v1.6.2 to pickup https://github.com/kubernetes/release/pull/2106
- debian-iptables: select nft mode if ntf lines > legacy lines, matching https://github.com/kubernetes-sigs/iptables-wrappers/ (#102590, @BenTheElder) [SIG Network and Testing]
We no longer allow the cluster operator to delete any "suggested" priority & fairness bootstrap configuration object, If a cluster operator removes a suggested configuration, it will be restored by the apiserver. (#102067, @tkashem) [SIG API Machinery]

Other (Cleanup or Flake)

Allow CSI drivers to just run offline expansion tests (#102665, @gnufied) [SIG Storage and Testing]
Changed buildmode of non static Kubernetes binaries to produce position independent executables (PIE). (#102323, @saschagrunert) [SIG Release and Security]
Clarified the description of a test in the e2e suite that mentions "SCTP" but is actually intended to be testing the behavior of network plugins that don't implement SCTP. (#102509, @danwinship) [SIG Network and Testing]
Disable log sampling when using json logging format (#102620, @serathius) [SIG API Machinery, Cluster Lifecycle and Instrumentation]
Improve func ToSelectableFields' performance for event (#102461, @goodluckbot) [SIG API Machinery and Node]
Migrate some log messages to structured logging in pkg/volume/plugins.go. (#101510, @huchengze) [SIG Storage]
Update CNI plugins to v0.9.1 (#102328, @lentzi90) [SIG Cloud Provider, Network, Node and Testing]
Updated pause image to version 3.5, which now runs per default as pseudo user and group 65535:65535. This does not have any effect on remote container runtimes like CRI-O and containerd, which setup the pod sandbox user and group on their own. (#100292, @saschagrunert) [SIG CLI, Cloud Provider, Cluster Lifecycle, Node and Testing]
Upgrade functionality of kubectl kustomize as described at https://github.com/kubernetes-sigs/kustomize/releases/tag/kustomize%2Fv4.1.3 (#102193, @gautierdelorme) [SIG CLI]

Changelog since v1.22.0-alpha.1

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

Intree volume plugin scaleio support is been completely removed from Kubernetes. (#101685, @Jiawei0227) [SIG API Machinery, Node and Storage]
Newly provisioned PVs by Azure disk will no longer have the beta FailureDomain label. Azure disk volume plugin will start to have GA topology label instead. (#101534, @kassarl) [SIG Cloud Provider and Storage]
Scheduler's CycleState now embeds internal read/write locking inside its Read() and Write() functions. Meanwhile, Lock() and Unlock() function are removed.

scheduler plugin developers are now required to remove CycleState#Lock() and CycleState#Unlock(). Just simply use Read() and Write() as they're natively thread-safe now. (#101542, @Huang-Wei) [SIG Scheduling and Storage]

Changes by Kind

Deprecation

Controller-manager: the following flags have no effect and would be removed in v1.24:
- --port
- --address The insecure port flags --port may only be set to 0 now.
In addtion, please be careful that:
- controller-manager MUST start with --authorization-kubeconfig and --authentication-kubeconfig correctly set to get authentication/authorization working.
- liveness/readiness probes to controller-manager MUST use HTTPS now, and the default port has been changed to 10257.
- Applications that fetch metrics from controller-manager should use a dedicated service account which is allowed to access nonResourceURLs /metrics. (#96216, @knight42) [SIG API Machinery, Cloud Provider, Instrumentation and Testing]
Ingress v1beta1 has been deprecated (#102030, @aojea) [SIG CLI, Network and Testing]
Kubeadm: remove the deprecated --csr-only and --csr-dir flags from "kubeadm init phase certs". Deprecate the same flags under "kubeadm certs renew". In both cases the command "kubeadm certs generate-csr" should be used instead. (#102108, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: remove the ClusterStatus API from v1beta3 and its management in the kube-system/kubeadm-config ConfigMap. This method of keeping track of what API endpoints exists in the cluster was replaced (in a prior release) by a method to annotate the etcd Pods that kubeadm creates in "stacked etcd" clusters. The following CLI sub-phases are deprecated and are now a NO-OP: for " kubeadm join": "control-plane-join/update-status", for "kubeadm reset": "update-cluster-status". Unless you are using these phases explicitly, you should not be affected. (#101915, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: remove the deprecated command "kubeadm alpha kubeconfig". Please use "kubeadm kubeconfig" instead. (#101938, @knight42) [SIG Cluster Lifecycle]
Kubeadm: remove the deprecated command 'kubeadm config view'. A replacement for this command is 'kubectl get cm -n kube-system kubeadm-config -o=jsonpath="{.data.ClusterConfiguration}"' (#102071, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: remove the deprecated flag --image-pull-timeout for 'kubeadm upgrade apply' command (#102093, @SataQiu) [SIG Cluster Lifecycle]
Kubeadm: remove the deprecated flag --insecure-port from the kube-apiserver manifest that kubeadm manages. The flag had no effect since 1.20, since the insecure serving of the component was disabled in the same version. (#102121, @pacoxu) [SIG Cluster Lifecycle]
Kubeadm: remove the deprecated hyperkube image support in v1beta3. This implies removal of ClusterConfiguration.UseHyperKubeImage. (#101537, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: remove the field ClusterConfiguration.DNS.Type in v1beta3 since CoreDNS is the only supported DNS type. (#101547, @neolit123) [SIG Cluster Lifecycle]
storageos,quobyte and flocker storage volume plugins are deprecated and will be removed in a later release. (#101773, @Jiawei0227) [SIG Storage]

API Change

Add alpha support for HostProcess containers on Windows (#99576, @marosset) [SIG API Machinery, Apps, Node, Testing and Windows]
Add three metrics to job controller to monitor if Job works in a healthy condition. IndexedJob promoted to Beta (#101292, @AliceZhang2016) [SIG Apps, Instrumentation and Testing]
Corrected the documentation for escaping dollar signs in a container's env, command and args property. (#101916, @MartinKanters) [SIG Apps]
Omit comparison with boolean constant (#101523, @GreenApple10) [SIG CLI and Cloud Provider]
Pod Affinity NamespaceSelector and the associated CrossNamespaceAffinity quota scope graduated to beta (#101496, @ahg-g) [SIG API Machinery, Apps and Testing]
V1.Node .status.images[].names is now optional (#102159, @roycaihw) [SIG Apps and Node]

Feature

Feat: change parittion style to GPT on Windows (#101412, @andyzhangx) [SIG Storage and Windows]
Improve logging of APIService availability changes in kube-apiserver. (#101420, @sttts) [SIG API Machinery]
Kubeadm: add the RootlessControlPlane kubeadm specific feature gate (Alpha in 1.22, disabled by default). It can be used to enable an experimental feature that makes the control plane component static Pod containers for kube-apiserver, kube-controller-manager, kube-scheduler and etcd to run as a non-root users. (#102158, @vinayakankugoyal) [SIG Cluster Lifecycle]
Kubeadm: set the seccompProfile to runtime/default in the PodSecurityContext of the control-plane components that run as static Pods. (#100234, @vinayakankugoyal) [SIG Cluster Lifecycle]
Kubernetes is now built with Golang 1.16.4 (#101809, @justaugustus) [SIG Cloud Provider, Instrumentation, Release and Testing]
Metrics server nanny has now poll period set to 30s (previously 5 minutes) to allow faster scaling of metrics server. (#101869, @olagacek) [SIG Cloud Provider and Instrumentation]
New metrics: apiserver_kube_aggregator_x509_missing_san_total and apiserver_webhooks_x509_missing_san_total. This metric measures a number of connections to webhooks/aggregated API servers that use certificates without Subject Alternative Names. It being non-zero is a warning sign that these connections will stop functioning in the future since Golang is going to deprecate x509 certificate subject Common Names for server hostname verification. (#95396, @stlaz) [SIG API Machinery, Auth and Instrumentation]
Node Problem Detector is now available for GCE Windows nodes. (#101539, @jeremyje) [SIG Cloud Provider, Node and Windows]
Secret values are now masked by default in kubectl diff output. (#96084, @loozhengyuan) [SIG CLI]
The WarningHeader feature is now GA and is unconditionally enabled. The apiserver_requested_deprecated_apis metric has graduated to stable status. The WarningHeader feature-gate is no longer operative and will be removed in v1.24. (#100754, @liggitt) [SIG API Machinery, Instrumentation and Testing]
Warnings for use of deprecated and known-bad values in pod specs are now sent (#101688, @liggitt) [SIG API Machinery and Auth]
You can use this Builder function to create events Field Selector (#101817, @cndoit18) [SIG API Machinery and Scalability]

The conformance tests:
- Services should serve multiport endpoints from pods
- Services should serve a basic endpoint from pods were only validating the API objects, not performing any validation on the actual Services implementation.

Changelog since v1.21.0

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

Audit log files are now created with a mode of 0600. Existing file permissions will not be changed. If you need the audit file to be readable by a non-root user, you can pre-create the file with the desired permissions. (#95387, @JAORMX) [SIG API Machinery and Auth]

Deprecation

Kubeadm: remove the deprecated kubeadm API v1beta1. Introduce a new kubeadm API v1beta3. See https://pkg.go.dev/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta3 for a list of changes since v1beta2. Note that v1beta2 is not yet deprecated, but will be in a future release. (#101129, @neolit123) [SIG Cluster Lifecycle]
PodUnknown phase is now deprecated. (#95286, @SergeyKanzhelev) [SIG Apps, CLI, Network, Node, Storage and Testing]
Removal of the CSI nodepublish path by the kubelet is deprecated. This must be done by the CSI plugin according to the CSI spec. (#101441, @dobsonj) [SIG Storage]

API Change

"Auto" is now a valid value for the service.kubernetes.io/topology-aware-hints annotation. (#100728, @robscott) [SIG Apps, Instrumentation and Network]
Kube-apiserver: --service-account-issuer can be specified multiple times now, to enable non-disruptive change of issuer. (#101155, @zshihang) [SIG API Machinery, Auth, Node and Testing]
New "node-high" priority-level has been added to Suggested API Priority and Fairness configuration. (#101151, @mborsz) [SIG API Machinery]
PodDeletionCost promoted to Beta (#101080, @ahg-g) [SIG Apps]
SSA treats certain structs as atomic (#100684, @Jefftree) [SIG API Machinery, Auth, Node and Storage]
Server Side Apply now treats all Selector fields as atomic (meaning the entire selector is managed by a single writer and updated together), since they contain interrelated and inseparable fields that do not merge in intuitive ways. (#97989, @Danil-Grigorev) [SIG API Machinery]
The pods/ephemeralcontainers API now returns and expects a Pod object instead of EphemeralContainers. This is incompatible with the previous alpha-level API. (#101034, @verb) [SIG Apps, Auth, CLI and Testing]
The pod/eviction subresource now accepts policy/v1 Eviction requests in addition to policy/v1beta1 Eviction requests (#100724, @liggitt) [SIG API Machinery, Apps, Architecture, Auth, CLI, Storage and Testing]
Track ownership of scale subresource for all scalable resources i.e. Deployment, ReplicaSet, StatefulSet, ReplicationController, and Custom Resources. (#98377, @nodo) [SIG API Machinery and Testing]
We have added a new Priority & Fairness rule that exempts all probes (/readyz, /healthz, /livez) to prevent restarting of "healthy" kube-apiserver instance(s) by kubelet. (#100678, @tkashem) [SIG API Machinery]

Feature

It add two flags, --max-pods and --extended-resources (#100267, @Jeffwan) [SIG Node and Scalability]
Kube config is now exposed in the scheduler framework handle. Out-of-tree plugins can leverage that to build CRD informers easily. (#100644, @Huang-Wei) [SIG Apps, Scheduling and Testing]
Kubeadm: add --validity-period flag for 'kubeadm kubeconfig user' command (#100907, @SataQiu) [SIG Cluster Lifecycle]

Run etcd as non-root on GCE provider' (#100635, @cindy52) [SIG Cloud Provider]
SSA is GA (#100139, @Jefftree) [SIG API Machinery]
System-cluster-critical pods should not get a low OOM Score.

As of now both system-node-critical and system-cluster-critical pods have -997 OOM score, making them one of the last processes to be OOMKilled. By definition system-cluster-critical pods can be scheduled elsewhere if there is a resource crunch on the node where as system-node-critical pods cannot be rescheduled. This was the reason for system-node-critical to have higher priority value than system-cluster-critical. This change allows only system-node-critical priority class to have low OOMScore.

action required If the user wants to have the pod to be OOMKilled last and the pod has system-cluster-critical priority class, it has to be changed to system-node-critical priority class to preserve the existing behavior (#99729, @ravisantoshgudimetla) [SIG Node]
The job controller removes running pods when the number of completions was achieved. (#99963, @alculquicondor) [SIG Apps]
kubectl describe will by default fetch large lists of resources in chunks of up to 500 items rather than requesting all resources up front from the server. A new flag --chunk-size=SIZE may be used to alter the number of items or disable this feature when 0 is passed. This is a beta feature. (#101171, @KnVerey) [SIG CLI and Testing]
kubectl drain will by default fetch large lists of resources in chunks of up to 500 items rather than requesting all resources up front from the server. A new flag --chunk-size=SIZE may be used to alter the number of items or disable this feature when 0 is passed. This is a beta feature. (#100148, @KnVerey) [SIG CLI and Testing]

Failing Test

Fixed generic ephemeal volumes with OwnerReferencesPermissionEnforcement admission plugin enabled. (#101186, @jsafrane) [SIG Auth and Storage]
Fixes kubectl drain --dry-run=server (#100206, @KnVerey) [SIG CLI and Testing]

Fire an event when failing to open NodePort (#100599, @masap) [SIG Network]
Fix a bug in kube-proxy latency metrics to calculate only the latency value for the endpoints that are created after it starts running. This is needed because all the endpoints objects are processed on restarts, independently when they were generated. (#100861, @aojea) [SIG Instrumentation and Network]
Fix availability set cache in vmss cache (#100110, @CecileRobertMichon) [SIG Cloud Provider]

Generated OpenAPI now correctly specifies 201 as a possible response code for PATCH operations (#100141, @brendandburns) [SIG API Machinery]
KCM sets the upper-bound timeout limit for outgoing requests to 70s. Previously no timeout was set. Requests without explicit timeout might potentially hang forever and lead to starvation of the application. (#99358, @p0lyn0mial) [SIG API Machinery]
Kubeadm: enable --experimental-patches flag for 'kubeadm join phase control-plane-join all' command (#101110, @SataQiu) [SIG Cluster Lifecycle]

Renames the timeout field for the DelegatingAuthenticationOptions to TokenRequestTimeout and set the timeout only for the token review client. Previously the timeout was also applied to watches making them reconnecting every 10 seconds. (#100959, @p0lyn0mial) [SIG API Machinery, Auth and Cloud Provider]
Reorganized iptables rules to reduce rules in KUBE-SERVICES and KUBE-NODEPORTS chains and improve performance (#96959, @tssurya) [SIG Network]
