Changelog since v1.18.0-alpha.2

Changes by Kind

Deprecation

  • Remove all the generators from kubectl run. It will now only create pods. Additionally, deprecates all the flags that are not relevant anymore. (#87077, @soltysh) [SIG Architecture, SIG CLI, and SIG Testing]
  • kubeadm: kube-dns is deprecated and will not be supported in a future version (#86574, @SataQiu) [SIG Cluster Lifecycle]

API Change

  • Add kubescheduler.config.k8s.io/v1alpha2 (#87628, @alculquicondor) [SIG Scheduling]
  • --enable-cadvisor-endpoints is now disabled by default. If you need access to the cAdvisor v1 Json API please enable it explicitly in the kubelet command line. Please note that this flag was deprecated in 1.15 and will be removed in 1.19. (#87440, @dims) [SIG Instrumentation, SIG Node, and SIG Testing]
  • The following feature gates are removed, because the associated features were unconditionally enabled in previous releases: CustomResourceValidation, CustomResourceSubresources, CustomResourceWebhookConversion, CustomResourcePublishOpenAPI, CustomResourceDefaulting (#87475, @liggitt) [SIG API Machinery]

Feature

  • aggragation api will have alpha support for network proxy (#87515, @Sh4d1) [SIG API Machinery]

  • API request throttling (due to a high rate of requests) is now reported in client-go logs at log level 2. The messages are of the form

    Throttling request took 1.50705208s, request: GET:

    The presence of these messages, may indicate to the administrator the need to tune the cluster accordingly. (#87740, @jennybuckley) [SIG API Machinery]

  • kubeadm: reject a node joining the cluster if a node with the same name already exists (#81056, @neolit123) [SIG Cluster Lifecycle]

  • disableAvailabilitySetNodes is added to avoid VM list for VMSS clusters. It should only be used when vmType is "vmss" and all the nodes (including masters) are VMSS virtual machines. (#87685, @feiskyer) [SIG Cloud Provider]

  • The kubectl --dry-run flag now accepts the values 'client', 'server', and 'none', to support client-side and server-side dry-run strategies. The boolean and unset values for the --dry-run flag are deprecated and a value will be required in a future version. (#87580, @julianvmodesto) [SIG CLI]

  • Add support for pre-allocated hugepages for more than one page size (#82820, @odinuge) [SIG Apps]

  • Update CNI version to v0.8.5 (#78819, @justaugustus) [SIG API Machinery, SIG Cluster Lifecycle, SIG Network, SIG Release, and SIG Testing]

  • Skip default spreading scoring plugin for pods that define TopologySpreadConstraints (#87566, @skilxn-go) [SIG Scheduling]

  • Added more details to taint toleration errors (#87250, @starizard) [SIG Apps, and SIG Scheduling]

  • Scheduler: Add DefaultBinder plugin (#87430, @alculquicondor) [SIG Scheduling, and SIG Testing]

  • Kube-apiserver metrics will now include request counts, latencies, and response sizes for /healthz, /livez, and /readyz requests. (#83598, @jktomer) [SIG API Machinery]

Other (Bug, Cleanup or Flake)

  • Fix the masters rolling upgrade causing thundering herd of LISTs on etcd leading to control plane unavailability. (#86430, @wojtek-t) [SIG API Machinery, SIG Node, and SIG Testing]
  • kubectl diff now returns 1 only on diff finding changes, and >1 on kubectl errors. The "exit status code 1" message as also been muted. (#87437, @apelisse) [SIG CLI, and SIG Testing]
  • To reduce chances of throttling, VM cache is set to nil when Azure node provisioning state is deleting (#87635, @feiskyer) [SIG Cloud Provider]
  • Fix regression in statefulset conversion which prevented applying a statefulset multiple times. (#87706, @liggitt) [SIG Apps, and SIG Testing]
  • fixed two scheduler metrics (pending_pods and schedule_attempts_total) not being recorded (#87692, @everpeace) [SIG Scheduling]
  • Resolved a performance issue in the node authorizer index maintenance. (#87693, @liggitt) [SIG Auth]
  • Removed the 'client' label from apiserver_request_total. (#87669, @logicalhan) [SIG API Machinery, and SIG Instrumentation]
  • (*"k8s.io/client-go/rest".Request).{Do,DoRaw,Stream,Watch} now require callers to pass a context.Context as an argument. The context is used for timeout and cancellation signaling and to pass supplementary information to round trippers in the wrapped transport chain. If you don't need any of this functionality, it is sufficient to pass a context created with context.Background() to these functions. The (*"k8s.io/client-go/rest".Request).Context method is removed now that all methods that execute a request accept a context directly. (#87597, @mikedanese) [SIG API Machinery, SIG Apps, SIG Auth, SIG Autoscaling, SIG CLI, SIG Cloud Provider, SIG Cluster Lifecycle, SIG Instrumentation, SIG Network, SIG Node, SIG Scheduling, SIG Storage, and SIG Testing]
  • For volumes that allow attaches across multiple nodes, attach and detach operations across different nodes are now executed in parallel. (#87258, @verult) [SIG Apps, SIG Node, and SIG Storage]
  • kubeadm: apply further improvements to the tentative support for concurrent etcd member join. Fixes a bug where multiple members can receive the same hostname. Increase the etcd client dial timeout and retry timeout for add/remove/... operations. (#87505, @neolit123) [SIG Cluster Lifecycle]
  • Reverted a kubectl azure auth module change where oidc claim spn: prefix was omitted resulting a breaking behavior with existing Azure AD OIDC enabled api-server (#87507, @weinong) [SIG API Machinery, SIG Auth, and SIG Cloud Provider]
  • Update cri-tools to v1.17.0 (#86305, @saschagrunert) [SIG Cluster Lifecycle, and SIG Release]
  • kubeadm: remove the deprecated CoreDNS feature-gate. It was set to "true" since v1.11 when the feature went GA. In v1.13 it was marked as deprecated and hidden from the CLI. (#87400, @neolit123) [SIG Cluster Lifecycle]
  • Shared informers are now more reliable in the face of network disruption. (#86015, @squeed) [SIG API Machinery]
  • the CSR signing cert/key pairs will be reloaded from disk like the kube-apiserver cert/key pairs (#86816, @deads2k) [SIG API Machinery, SIG Apps, and SIG Auth]
  • "kubectl describe statefulsets.apps" prints garbage for rolling update partition (#85846, @phil9909) [SIG CLI]

Changelog since v1.17.0

Action Required

  • action required (#85363, @immutableT)
      1. Currently, if users were to explicitly specify CacheSize of 0 for KMS provider, they would end-up with a provider that caches up to 1000 keys. This PR changes this behavior.
    • Post this PR, when users supply 0 for CacheSize this will result in a validation error.
      1. CacheSize type was changed from int32 to *int32. This allows defaulting logic to differentiate between cases where users explicitly supplied 0 vs. not supplied any value.
      1. KMS Provider's endpoint (path to Unix socket) is now validated when the EncryptionConfiguration files is loaded. This used to be handled by the GRPCService.

    • Throttling request took 1.50705208s, request: GET:
    • The presence of large numbers of these messages, particularly with long delay times, may indicate to the administrator the need to tune the cluster accordingly.
  • Fix API Server potential memory leak issue in processing watch request. (#85410, @answer1991)
  • Verify kubelet & kube-proxy can recover after being killed on Windows nodes (#84886, @YangLu1031)
