Changelog since v1.24.0-alpha.4

Changes by Kind

Deprecation

  • Remove insecure serving configuration from cloud-provider package, which is consumed by cloud-controller-managers. (#108953, @nckturner) [SIG Cloud Provider and Testing]

  • The metadata.clusterName field is deprecated. This field has always been unwritable and always blank, but its presence is confusing, so we will remove it next release. Out of an abundance of caution, this release we have merely changed the name in the go struct to ensure any accidental client uses are found before complete removal. (#108717, @lavalamp) [SIG API Machinery, Apps, Auth, Scheduling and Testing]

  • VSphere releases less than 7.0u2 are deprecated as of v1.24. Please consider upgrading vSphere to 7.0u2 or above. vSphere CSI Driver requires minimum vSphere 7.0u2.

    General Support for vSphere 6.7 will end on October 15, 2022. vSphere 6.7 Update 3 is deprecated in Kubernetes v1.24. Customers are recommended to upgrade vSphere (both ESXi and vCenter) to 7.0u2 or above. vSphere CSI Driver 2.2.3 and higher supports CSI Migration.

    Support for these deprecations will be available till October 15, 2022. (#109089, @deepakkinni) [SIG Cloud Provider]

API Change

  • Adds a new Status subresource in Network Policy objects (#107963, @rikatz) [SIG API Machinery, Apps, Network and Testing]
  • Adds support for "InterfaceNamePrefix" and "BridgeInterface" as arguments to --detect-local-mode option and also introduces a new optional --pod-interface-name-prefix and --pod-bridge-interface flags to kube-proxy. (#95400, @tssurya) [SIG API Machinery and Network]
  • CEL CRD validation expressions may now reference existing object state using the identifier oldSelf. (#108073, @benluddy) [SIG API Machinery and Testing]
  • CSIStorageCapacity.storage.k8s.io: The v1beta1 version of this API is deprecated in favor of v1, and will be removed in v1.27. If a CSI driver supports storage capacity tracking, then it must get deployed with a release of external-provisioner that supports the v1 API. (#108445, @pohly) [SIG API Machinery, Architecture, Auth, Scheduling, Storage and Testing]
  • Custom resource requests with fieldValidation=Strict consistently require apiVersion and kind, matching non-strict requests (#109019, @liggitt) [SIG API Machinery]
  • Improve kubectl's user help commands readability (#104736, @lauchokyip) [SIG API Machinery, Apps, Architecture, Auth, Autoscaling, CLI, Cloud Provider, Cluster Lifecycle, Contributor Experience, Instrumentation, Network, Node, Release, Scalability, Scheduling, Security, Storage, Testing and Windows]
  • Indexed Jobs graduates to stable (#107395, @alculquicondor) [SIG Apps, Architecture and Testing]
  • Introduce a v1alpha1 networking API for ClusterCIDRConfig (#108290, @sarveshr7) [SIG API Machinery, Apps, Auth, CLI, Cloud Provider, Instrumentation, Network and Testing]
  • JobReadyPods graduates to Beta and it's enabled by default. (#107476, @alculquicondor) [SIG API Machinery, Apps and Testing]
  • Kubelet external Credential Provider feature is moved to Beta. Credential Provider Plugin and Credential Provider Config API's updated from v1alpha1 to v1beta1 with no API changes. (#108847, @adisky) [SIG API Machinery and Node]
  • MaxUnavailable for StatefulSets, allows faster RollingUpdate by taking down more than 1 pod at a time. The number of pods you want to take down during a RollingUpdate is configurable using maxUnavailable parameter. (#82162, @krmayankk) [SIG API Machinery and Apps]
  • Non graceful node shutdown handling. (#108486, @sonasingh46) [SIG Apps, Node and Storage]
  • OpenAPI V3 is turned on by default (#109031, @Jefftree) [SIG API Machinery, Apps, Architecture, Auth, Autoscaling, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Scheduling, Storage and Testing]
  • Promote IdentifyPodOS feature to beta. (#107859, @ravisantoshgudimetla) [SIG API Machinery, Apps, Node, Testing and Windows]
  • Skip x-kubernetes-validations rules if having fundamental error against OpenAPIv3 schema. (#108859, @cici37) [SIG API Machinery and Testing]
  • Support for gRPC probes is now in beta. GRPCContainerProbe feature gate is enabled by default. (#108522, @SergeyKanzhelev) [SIG API Machinery, Apps, Node and Testing]
  • The AnyVolumeDataSource feature is now beta, and the feature gate is enabled by default. In order to provide user feedback on PVCs with data sources, deployers must install the VolumePopulators CRD and the data-source-validator controller. (#108736, @bswartz) [SIG Apps, Storage and Testing]
  • The ServerSideFieldValidation feature has graduated to beta and is now enabled by default. Kubectl 1.24 and newer will use server-side validation instead of client-side validation when writing to API servers with the feature enabled. (#108889, @kevindelgado) [SIG API Machinery, Architecture, CLI and Testing]
  • The infrastructure for contextual logging is complete (feature gate implemented, JSON backend ready). (#108995, @pohly) [SIG API Machinery, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Scheduling and Testing]
  • This adds an optional timeZone field as part of the CronJob spec to support running cron jobs in a specific time zone. (#108032, @deejross) [SIG API Machinery and Apps]

Feature

  • Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:

    • Adds OpenAPIV3SchemaInterface to DiscoveryClient and its variants for fetching OpenAPI v3 schema documents. (#108992, @alexzielenski) [SIG API Machinery, Architecture, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]
  • Allow kubectl to manage resources by filename patterns without the shell expanding it first (#102265, @danielrodriguez) [SIG CLI]

  • An alpha flag --subresource is added to get, patch, edit replace kubectl commands to fetch and update status and scale subresources. (#99556, @nikhita) [SIG API Machinery, CLI and Testing]

  • Apiextensions_openapi_v3_regeneration_count metric (alpha) will be emitted for OpenAPI V3. (#109128, @Jefftree) [SIG API Machinery and Instrumentation]

  • Apply ProxyTerminatingEndpoints to all traffic policies (external, internal, cluster, local). (#108691, @andrewsykim) [SIG Network and Testing]

  • CEL regex patterns in x-kubernetes-valiation rules are compiled when CRDs are created/updated if the pattern is provided as a string constant in the expression. Any regex compile errors are reported as a CRD create/update validation error. (#108617, @jpbetz) [SIG API Machinery, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]

  • Changes the kubectl --validate flag from a bool to a string that accepts the values {true, strict, warn, false, ignore}

    • true/strict - perform validation and error the request on any invalid fields in the ojbect. It will attempt to perform server-side validation if it is enabled on the apiserver, otherwise it will fall back to client-side validation.
    • warn - perform server-side validation and warn on any invalid fields (but ultimately let the request succeed by dropping any invalid fields from the object). If validation is not available on the server, perform no validation.
    • false/ignore - perform no validation, silently dropping invalid fields from the object. (#108350, @kevindelgado) [SIG API Machinery, CLI, Node and Testing]
  • CycleState is now optimized for "write once and read many times". (#108724, @sanposhiho) [SIG Scheduling]

  • Enable beta feature HonorPVReclaimPolicy by default. (#109035, @deepakkinni) [SIG Apps and Storage]

  • Kube-apiserver: Subresources such as 'status' and 'scale' now support tabular output content types. (#103516, @ykakarap) [SIG API Machinery, Auth and Testing]

  • Kubeadm: add the flag "--experimental-initial-corrupt-check" to etcd static Pod manifests to ensure etcd member data consistency (#109074, @neolit123) [SIG Cluster Lifecycle]

  • Kubectl now supports shell completion for the / format for specifying resources.

    kubectl now provides shell completion for container names following the --container/-c flag of the exec command.

    kubectl's shell completion now suggests resource types for commands that only apply to pods. (#108493, @marckhouzam) [SIG CLI]

  • Kubelet now creates an iptables chain named KUBE-IPTABLES-HINT in the mangle table. Containerized components that need to modify iptables rules in the host network namespace can use the existence of this chain to more-reliably determine whether the system is using iptables-legacy or iptables-nft. (#109059, @danwinship) [SIG Network and Node]

  • Kubernetes 1.24 bumped version of golang it is compiled with to go1.18, which introduced significant changes to its garbage collection algorithm. As a result, we observed an increase in memory usage for kube-apiserver in larger an heavily loaded clusters up to ~25% (with the benefit of API call latencies drop by up to 10x on 99th percentiles). If the memory increase is not acceptable for you you can mitigate by setting GOGC env variable (for our tests using GOGC=63 brings memory usage back to original value, although the exact value may depend on usage patterns on your cluster). (#108870, @dims) [SIG Architecture, Release and Testing]

  • Leader Migration is now GA. All new configuration files onwards should use version v1. (#109072, @jiahuif) [SIG Cloud Provider]

  • Mark AzureDisk CSI migration as GA (#107681, @andyzhangx) [SIG Cloud Provider and Storage]

  • Move volume expansion feature to GA (#108929, @gnufied) [SIG API Machinery, Apps, Auth, Node, Storage and Testing]

  • New "field_validation_request_duration_seconds" metric, measures how long requests take, indicating the value of the fieldValidation query parameter and whether or not server-side field validation is enabled on the apiserver (#109120, @kevindelgado) [SIG API Machinery and Instrumentation]

  • New feature gate, ServiceIPStaticSubrange, to enable the new strategy in the Service IP allocators, so the IP range is subdivided and dynamic allocated ClusterIP addresses for Services are allocated preferently from the upper range. (#106792, @aojea) [SIG Instrumentation]

  • OpenAPI definitions served by kube-api-server now include enum types by default. (#108898, @jiahuif) [SIG API Machinery]

  • Promote graceful shutdown based on pod priority to beta (#107986, @wzshiming) [SIG Instrumentation, Node and Testing]

  • Update the k8s.io/system-validators library to v1.7.0 (#108988, @neolit123) [SIG Cluster Lifecycle]

  • Updates kubectl kustomize and kubectl apply -k to Kustomize v4.5.4 (#108994, @KnVerey) [SIG CLI]

  • kubectl version now includes information on the embedded version of Kustomize (#108817, @KnVerey) [SIG CLI and Testing]

Bug or Regression

  • A node IP provided to kublet via --node-ip will now be preferred for when determining the node's primary IP and using the external cloud provider (CCM). (#107750, @stephenfin) [SIG Cloud Provider and Node]
  • Add one metrics(kubelet_volume_stats_health_abnormal) of volume health state to kubelet (#108758, @fengzixu) [SIG Instrumentation, Node, Storage and Testing]
