v19.15.0a1

Kubernetes API Version: v1.19.15

Bug Fix

Feature

API Change

  • 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. (kubernetes/kubernetes#101113, @tkashem) [SIG API Machinery]
  • Fixes using server-side apply with APIService resources (kubernetes/kubernetes#100713, @kevindelgado) [SIG API Machinery, Apps, Scheduling and Testing]
  • Regenerate protobuf code to fix CVE-2021-3121 (kubernetes/kubernetes#100515, @joelsmith) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]
  • Kubernetes is now built using go1.15.8 (kubernetes/kubernetes#99093, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]
  • Fix conversions for custom metrics. (kubernetes/kubernetes#94654, @wojtek-t) [SIG Instrumentation]
  • A new alpha-level field, SupportsFsGroup, has been introduced for CSIDrivers to allow them to specify whether they support volume ownership and permission modifications. The CSIVolumeSupportFSGroup feature gate must be enabled to allow this field to be used. (kubernetes/kubernetes#92001, @huffmanca) [SIG API Machinery, CLI and Storage]
  • Added pod version skew strategy for seccomp profile to synchronize the deprecated annotations with the new API Server fields. Please see the corresponding section in the KEP for more detailed explanations. (kubernetes/kubernetes#91408, @saschagrunert) [SIG Apps, Auth, CLI and Node]
  • Adds the ability to disable Accelerator/GPU metrics collected by Kubelet (kubernetes/kubernetes#91930, @RenaudWasTaken) [SIG Node]
  • Admission webhooks can now return warning messages that are surfaced to API clients, using the .response.warnings field in the admission review response. (kubernetes/kubernetes#92667, @liggitt) [SIG API Machinery and Testing]
  • CertificateSigningRequest API conditions were updated:
    • a status field was added; this field defaults to True, and may only be set to True for Approved, Denied, and Failed conditions
    • a lastTransitionTime field was added
    • a Failed condition type was added to allow signers to indicate permanent failure; this condition can be added via the certificatesigningrequests/status subresource.
    • Approved and Denied conditions are mutually exclusive
    • Approved, Denied, and Failed conditions can no longer be removed from a CSR (kubernetes/kubernetes#90191, @liggitt) [SIG API Machinery, Apps, Auth, CLI and Node]

  • Seccomp support has graduated to GA. A new seccompProfile field is added to pod and container securityContext objects. Support for seccomp.security.alpha.kubernetes.io/pod and container.seccomp.security.alpha.kubernetes.io/... annotations is deprecated, and will be removed in v1.22. (kubernetes/kubernetes#91381, @pjbgf) [SIG Apps, Auth, Node, Release, Scheduling and Testing]
  • ServiceAppProtocol feature gate is now beta and enabled by default, adding new AppProtocol field to Services and Endpoints. (kubernetes/kubernetes#90023, @robscott) [SIG Apps and Network]
  • SetHostnameAsFQDN is a new field in PodSpec. When set to true, the fully qualified domain name (FQDN) of a Pod is set as hostname of its containers. In Linux containers, this means setting the FQDN in the hostname field of the kernel (the nodename field of struct utsname). In Windows containers, this means setting the this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters to FQDN. If a pod does not have FQDN, this has no effect. (kubernetes/kubernetes#91699, @javidiaz) [SIG Apps, Network, Node and Testing]

Bug Fix:

v17.14.0a1

Kubernetes API Version: 1.17.14

Important Information:

  • The Kubernetes Python client versioning scheme has changed. The version numbers used till Kubernetes Python Client v12.y.z lagged behind the actual Kubernetes minor version numbers. From this release, the client is moving a version format vY.Z.P where Y and Z are respectively from the Kubernetes version v1.Y.Z and P would incremented due to changes on the Python client side itself. Ref: kubernetes-client#1244
  • Python 2 had reached End of Life on January 1, 2020. The Kubernetes Python Client will drop support for Python 2 from the next release (v18.0.0) and will no longer provide support to older clients as per the Kubernetes support policy.

API Change:

  • Fixed: log timestamps now include trailing zeros to maintain a fixed width (#91207, @iamchuckss) [SIG Apps and Node]
  • Resolve regression in metadata.managedFields handling in update/patch requests submitted by older API clients (#92008, @apelisse) [SIG API Machinery and Testing]
  • Fix bug where sending a status update completely wipes managedFields for some types. (#90032, @apelisse) [SIG API Machinery and Testing]
  • Fixes a regression with clients prior to 1.15 not being able to update podIP in pod status, or podCIDR in node spec, against >= 1.16 API servers (#88505, @liggitt) [SIG Apps and Network]
  • CustomResourceDefinitions now validate documented API semantics of x-kubernetes-list-type and x-kubernetes-map-type atomic to reject non-atomic sub-types. (#84722, @sttts)
  • Kube-apiserver: The AdmissionConfiguration type accepted by --admission-control-config-file has been promoted to apiserver.config.k8s.io/v1 with no schema changes. (#85098, @liggitt)
  • Fixed EndpointSlice port name validation to match Endpoint port name validation (allowing port names longer than 15 characters) (#84481, @robscott)
  • CustomResourceDefinitions introduce x-kubernetes-map-type annotation as a CRD API extension. Enables this particular validation for server-side apply. (#84113, @enxebre)

  • Fix bug where sending a status update completely wipes managedFields for some types. (#90033, @apelisse) [SIG API Machinery and Testing]
  • The MutatingWebhookConfiguration and ValidatingWebhookConfiguration APIs have been promoted to admissionregistration.k8s.io/v1:
    • failurePolicy default changed from Ignore to Fail for v1
    • matchPolicy default changed from Exact to Equivalent for v1
    • timeout default changed from 30s to 10s for v1
    • sideEffects default value is removed, and the field made required, and only None and NoneOnDryRun are permitted for v1
    • admissionReviewVersions default value is removed and the field made required for v1 (supported versions for AdmissionReview are v1 and v1beta1)
    • The name field for specified webhooks must be unique for MutatingWebhookConfiguration and ValidatingWebhookConfiguration objects created via admissionregistration.k8s.io/v1
  • The AdmissionReview API sent to and received from admission webhooks has been promoted to admission.k8s.io/v1. Webhooks can specify a preference for receiving v1 AdmissionReview objects with admissionReviewVersions: ["v1","v1beta1"], and must respond with an API object in the same apiVersion they are sent. When webhooks use admission.k8s.io/v1, the following additional validation is performed on their responses:
    • response.patch and response.patchType are not permitted from validating admission webhooks
    • apiVersion: "admission.k8s.io/v1" is required
    • kind: "AdmissionReview" is required
    • response.uid: "<value of request.uid>" is required
    • response.patchType: "JSONPatch" is required (if response.patch is set) (#80231, @liggitt)

    • Use of the new default feature in validation schemas is limited to v1
    • spec.scope is no longer defaulted to Namespaced and must be explicitly specified
    • spec.version is removed in v1; use spec.versions instead
    • spec.validation is removed in v1; use spec.versions[*].schema instead
    • spec.subresources is removed in v1; use spec.versions[*].subresources instead
    • spec.additionalPrinterColumns is removed in v1; use spec.versions[*].additionalPrinterColumns instead
    • spec.conversion.webhookClientConfig is moved to spec.conversion.webhook.clientConfig in v1
    • spec.conversion.conversionReviewVersions is moved to spec.conversion.webhook.conversionReviewVersions in v1
    • spec.versions[*].schema.openAPIV3Schema is now required when creating v1 CustomResourceDefinitions
    • spec.preserveUnknownFields: true is disallowed when creating v1 CustomResourceDefinitions; it must be specified within schema definitions as x-kubernetes-preserve-unknown-fields: true
    • In additionalPrinterColumns items, the JSONPath field was renamed to jsonPath in v1 (fixes kubernetes/kubernetes#66531) The apiextensions.k8s.io/v1beta1 version of CustomResourceDefinition is deprecated and will no longer be served in v1.19. (#79604, @liggitt)
  • The ConversionReview API sent to and received from custom resource CustomResourceDefinition conversion webhooks has been promoted to apiextensions.k8s.io/v1. CustomResourceDefinition conversion webhooks can now indicate they support receiving and responding with ConversionReview API objects in the apiextensions.k8s.io/v1 version by including v1 in the conversionReviewVersions list in their CustomResourceDefinition. Conversion webhooks must respond with a ConversionReview object in the same apiVersion they receive. apiextensions.k8s.io/v1 ConversionReview responses must specify a response.uid that matches the request.uid of the object they were sent. (#81476, @liggitt)
  • Add scheduling support for RuntimeClasses. RuntimeClasses can now specify nodeSelector constraints & tolerations, which are merged into the PodSpec for pods using that RuntimeClass. (#80825, @tallclair)
  • Kubelet should now more reliably report the same primary node IP even if the set of node IPs reported by the CloudProvider changes. (#79391, @danwinship)
  • Omit nil or empty field when calculating container hash value to avoid hash changed. For a new field with a non-nil default value in the container spec, the hash would still get changed. (#57741, @dixudx)
  • Property conditions in apiextensions.v1beta1.CustomResourceDefinitionStatus and apiextensions.v1.CustomResourceDefinitionStatus is now optional instead of required. (#64996, @roycaihw)
  • When the status of a CustomResourceDefinition condition changes, its corresponding lastTransitionTime is now updated. (#69655, @CaoShuFeng)

v8.0.0b1

Bug Fix:

API Change:

v8.0.0a1

New Feature:

Bug Fix:

API Change:

  • Upon receiving a LIST request with expired continue token, the apiserver now returns a continue token together with the 410 "the from parameter is too old " error. If the client does not care about getting a list from a consistent snapshot, the client can use this token to continue listing from the next key, but the returned chunk will be from the latest snapshot kubernetes/kubernetes#67284
  • Introduces autoscaling/v2beta2 and custom_metrics/v1beta2, which implement metric selectors for Object and Pods metrics, as well as allowing AverageValue targets on Objects, similar to External metrics kubernetes/kubernetes#64097

Pods can select a RunitmeClass to use via the RuntimeClassName field. This feature is in alpha, and the RuntimeClass feature gate must be enabled in order to use it kubernetes/kubernetes#67737
  • The PodShareProcessNamespace feature to configure PID namespace sharing within a pod has been promoted to beta kubernetes/kubernetes#66507
  • To address the possibility dry-run requests overwhelming admission webhooks that rely on side effects and a reconciliation mechanism, a new field is being added to admissionregistration.k8s.io/v1beta1.ValidatingWebhookConfiguration and admissionregistration.k8s.io/v1beta1.MutatingWebhookConfiguration so that webhooks can explicitly register as having dry-run support. If a dry-run request is made on a resource that triggers a non dry-run supporting webhook, the request will be completely rejected, with "400: Bad Request". Additionally, a new field is being added to the admission.k8s.io/v1beta1.AdmissionReview API object, exposing to webhooks whether or not the request being reviewed is a dry-run kubernetes/kubernetes#66936
  • Add custom object status and scale api kubernetes-client/gen#72
