Changelog since v1.16.12

Urgent Upgrade Notes

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

  • CVE-2020-8559 (Medium): Privilege escalation from compromised node to cluster. See kubernetes#92914 for more details. The API Server will no longer proxy non-101 responses for upgrade requests. This could break proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code. (#92941, @tallclair) [SIG API Machinery]

Changes by Kind

Bug or Regression

  • CVE-2020-8557 (Medium): Node-local denial of service via container /etc/hosts file. See kubernetes#93032 for more details. (#92916, @joelsmith) [SIG Node]

  • Extend kube-apiserver /readyz with new "informer-sync" check ensuring that internal informers are synced. (#92644, @wojtek-t) [SIG API Machinery and Testing]

  • Fix: GetLabelsForVolume panic issue for azure disk PV (#92166, @andyzhangx) [SIG Cloud Provider]

  • Fix: use force detach for azure disk (#91948, @andyzhangx) [SIG Cloud Provider]

  • Fixes a problem with 63-second or 1-second connection delays with some VXLAN-based network plugins which was first widely noticed in 1.16 (though some users saw it earlier than that, possibly only with specific network plugins). If you were previously using ethtool to disable checksum offload on your primary network interface, you should now be able to stop doing that. (#92035, @danwinship) [SIG Network and Node]

  • Kubeadm: add the deprecated flag --port=0 to kube-controller-manager and kube-scheduler manifests to disable insecure serving. Without this flag the components by default serve (e.g. /metrics) insecurely on the default node interface (controlled by --address). Users that wish to override this behavior and enable insecure serving can pass a custom --port=X via kubeadm's "extraArgs" mechanic for these components. (#92720, @neolit123) [SIG Cluster Lifecycle]

  • hyperkube: Use debian-hyperkube-base@v1.1.1 image

    Includes iproute2 to fix a regression in hyperkube images when using hyperkube as a kubelet (#92626, @justaugustus) [SIG Cluster Lifecycle, Network and Release]

Changelog since v1.16.11

Changes by Kind

API Change

  • Fixed: log timestamps now include trailing zeros to maintain a fixed width (#91207, @iamchuckss) [SIG Apps and Node]

Bug or Regression

  • If firstTimestamp is not set use firstTimestamp or eventTime when printing event (#91056, @soltysh) [SIG CLI]

  • hyperkube: Use debian-hyperkube-base@v1.1.0 image

    A previous release built hyperkube using the debian-hyperkube-base@v1.0.0, which was updated to address a CVE in the CNI plugins.

    A side-effect of using this new image was that the networking packages (namely iptables) drifted from the versions used in the kube-proxy images.

    The following issues were filed on kube-proxy failures when using hyperkube:

    To address this, the new debian-hyperkube-base image (v1.1.0) uses the debian-iptables base image (v12.1.0), which includes iptables-wrapper, a script used to determine the correct iptables mode to run in. (#92495, @justaugustus) [SIG Cluster Lifecycle and Release]

Changelog since v1.16.11

Changes by Kind

API Change

  • Fixed: log timestamps now include trailing zeros to maintain a fixed width (#91207, @iamchuckss) [SIG Apps and Node]

Bug or Regression

  • If firstTimestamp is not set use firstTimestamp or eventTime when printing event (#91056, @soltysh) [SIG CLI]

  • hyperkube: Use debian-hyperkube-base@v1.1.0 image

    A previous release built hyperkube using the debian-hyperkube-base@v1.0.0, which was updated to address a CVE in the CNI plugins.

    A side-effect of using this new image was that the networking packages (namely iptables) drifted from the versions used in the kube-proxy images.

    The following issues were filed on kube-proxy failures when using hyperkube:

    To address this, the new debian-hyperkube-base image (v1.1.0) uses the debian-iptables base image (v12.1.0), which includes iptables-wrapper, a script used to determine the correct iptables mode to run in. (#92495, @justaugustus) [SIG Cluster Lifecycle and Release]

Changelog since v1.16.7

Changes by Kind

API Change

  • 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]

Other (Bug, Cleanup or Flake)

  • Add delays between goroutines for vm instance update (#88094, @aramase) [SIG Cloud Provider]
  • Build: Enable kube-cross image-building on K8s Infra (#88596, @justaugustus) [SIG Release and Testing]
  • Fix /readyz to return error immediately after a shutdown is initiated, before the --shutdown-delay-duration has elapsed. (#88954, @tkashem) [SIG API Machinery]
  • Fix a bug in kube-proxy that caused it to crash when using load balancers with a different IP family (#87117, @aojea) [SIG Network]
  • Fix a regression in kubenet that prevent pods to obtain ip addresses (#87287, @aojea) [SIG Network and Node]
  • Fix handling of aws-load-balancer-security-groups annotation. Security-Groups assigned with this annotation are no longer modified by kubernetes which is the expected behaviour of most users.

  • Filter published OpenAPI schema by making nullable, required fields non-required in order to avoid kubectl to wrongly reject null values. (#85733, @sttts)
  • For x-kubernetes-list-type=set a scalar or atomic item type is now required, as documented. Persisted, invalid data is tolerated. (#85385, @sttts)
  • Fixes a bug in kubeadm that caused init and join to hang indefinitely in specific conditions. (#85156, @chuckha)
  • Ensure health probes are created for local traffic policy UDP services on Azure (#84802, @feiskyer)

Kubernetes v1.16.0 Release Notes

A complete changelog for the release notes is now hosted in a customizable format at relnotes.k8s.io. Check it out and please give us your feedback!

What’s New (Major Themes)

We’re pleased to announce the delivery of Kubernetes 1.16, our third release of 2019! Kubernetes 1.16 consists of 31 enhancements: 8 enhancements moving to stable, 8 enhancements in beta, and 15 enhancements in alpha.

The main themes of this release are:

  • Custom resources: CRDs are in widespread use as a way to extend Kubernetes to persist and serve new resource types, and have been available in beta since the 1.7 release. The 1.16 release marks the graduation of CRDs to general availability (GA).
  • Admission webhooks: Admission webhooks are in widespread use as a Kubernetes extensibility mechanism and have been available in beta since the 1.9 release. The 1.16 release marks the graduation of admission webhooks to general availability (GA).
  • Overhauled metrics: Kubernetes has previously made extensive use of a global metrics registry to register metrics to be exposed. By implementing a metrics registry, metrics are registered in more transparent means. Previously, Kubernetes metrics have been excluded from any kind of stability requirements.
  • Volume Extension: There are quite a few enhancements in this release that pertain to volumes and volume modifications. Volume resizing support in CSI specs is moving to beta which allows for any CSI spec volume plugin to be resizable.

Additional Notable Feature Updates

  • Topology Manager, a new Kubelet component, aims to co-ordinate resource assignment decisions to provide optimized resource allocations.
  • IPv4/IPv6 dual-stack enables the allocation of both IPv4 and IPv6 addresses to Pods and Services.
  • API Server Network Proxy going alpha in 1.16.
  • Extensions for Cloud Controller Manager Migration.
  • Continued deprecation of extensions/v1beta1, apps/v1beta1, and apps/v1beta2 APIs; these extensions will be retired in 1.16!

Known Issues

  • The etcd and KMS plugin health checks are not exposed in the new livez and readyz endpoints. This will be fixed in 1.16.1.
  • Systems running iptables 1.8.0 or newer should start it in legacy mode. Please note that this affects all versions of Kubernetes and not only v1.16.0. For more detailed information about the issue and how to apply a workaround, please refer to the official documentation
  • Generating informers for packages in directories containing dots in their name is broken. This will be fixed in v1.16.1. (#82860)
  • kube-scheduler won't be able to report scheduling Events if events.k8s.io/v1beta1 API is disabled. We are targeting the fix for v1.16.2 (#83203)
  • The etcd client library vendored in v1.16 (github.com/coreos/etcd/clientv3) has a bug where IPv6 IP addresses get incorrectly trimmed to the first occurance of the : character. This affects all users of the client library including the kube-apiserver and kubeadm. We are targeting the fix for this bug in v1.16.3. (#83550)

Urgent Upgrade Notes

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

Cluster Lifecycle

  • Container images tar files for amd64 will now contain the architecture in the RepoTags manifest.json section. If you are using docker manifests there are not visible changes. (#80266, @javier-b-perez)
  • kubeadm now deletes the bootstrap-kubelet.conf file after TLS bootstrap User relying on bootstrap-kubelet.conf should switch to kubelet.conf that contains node credentials (#80676, @fabriziopandini)
  • Node labels beta.kubernetes.io/metadata-proxy-ready, beta.kubernetes.io/metadata-proxy-ready and beta.kubernetes.io/kube-proxy-ds-ready are no longer added on new nodes.
    • ip-mask-agent addon starts to use the label node.kubernetes.io/masq-agent-ds-ready instead of beta.kubernetes.io/masq-agent-ds-ready as its node selector.
    • kube-proxy addon starts to use the label node.kubernetes.io/kube-proxy-ds-ready instead of beta.kubernetes.io/kube-proxy-ds-ready as its node selector.
    • metadata-proxy addon starts to use the label cloud.google.com/metadata-proxy-ready instead of beta.kubernetes.io/metadata-proxy-ready as its node selector.

Storage

  • When PodInfoOnMount is enabled for a CSI driver, the new csi.storage.k8s.io/ephemeral parameter in the volume context allows a driver's NodePublishVolume implementation to determine on a case-by-case basis whether the volume is ephemeral or a normal persistent volume (#79983, @pohly)
  • Add CSI Migration Shim for VerifyVolumesAreAttached and BulkVolumeVerify (#80443, @davidz627)
  • Promotes VolumePVCDataSource (Cloning) feature to beta for 1.16 release (#81792, @j-griffith)
  • Integrated volume limits for in-tree and CSI volumes into one scheduler predicate. (#77595, @bertinatto)

Deprecations and Removals

  • API

    • The following APIs are no longer served by default:

      • All resources under apps/v1beta1 and apps/v1beta2 - use apps/v1 instead
      • daemonsets, deployments, replicasets resources under extensions/v1beta1 - use apps/v1 instead
      • networkpolicies resources under extensions/v1beta1 - use networking.k8s.io/v1 instead
      • podsecuritypolicies resources under extensions/v1beta1 - use policy/v1beta1 instead

      Serving these resources can be temporarily re-enabled using the --runtime-config apiserver flag.

See https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/#specifying-a-structural-schema for details. (#81872, @sttts)
  • Finalizer Protection for Service LoadBalancers is now in beta (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted. (#81691, @MrHohn)
  • Graduating Windows GMSA support from alpha to beta (#82110, @wk8)

Alpha

  • Introduce a new admission controller for RuntimeClass. Initially, RuntimeClass will be used to apply the pod overhead associated with a given RuntimeClass to the Pod spec if a corresponding RuntimeClassName is specified. PodOverhead is an alpha feature as of Kubernetes 1.16. (#78484, @egernst)
  • Introduction of the pod overhead feature to the scheduler. This functionality is alpha-level as of Kubernetes v1.16, and is only honored by servers that enable the PodOverhead feature.gate. (#78319, @egernst)
  • Ephemeral containers have been added in alpha. These temporary containers can be added to running pods for purposes such as debugging, similar to how kubectl exec runs a process in an existing container. Also like kubectl exec, no resources are reserved for ephemeral containers and they are not restarted when they exit. Note that container namespace targeting is not yet implemented, so process namespace sharing must be enabled to view process from other containers in the pod. (#59484, @verb)
  • Pod spread constraints have been added in alpha. You can use these constraints to control how Pods are spread across the cluster among failure-domains. (#77327, #77760, #77828, #79062, #80011, #81068, @Huang-Wei)

CLI Improvements

  • the new flag --endpoint-updates-batch-period in kube-controller-manager can be used to reduce the number of endpoints updates generated by pod changes. (#80509, @mborsz)
  • the kubectl --all-namespaces flag is now honored by kubectl wait (#81468, @ashutoshgngwr)
  • kubectl get -w now takes an --output-watch-events flag to indicate the event type (ADDED, MODIFIED, DELETED) (#72416, @liggitt)
  • Adds Endpoint Slice support for kubectl when discovery API group is enabled. (#81795, @robscott)

Misc

  • Add --shutdown-delay-duration to kube-apiserver in order to delay a graceful shutdown. /healthz will keep returning success during this time and requests are normally served, but /readyz will return failure immediately. This delay can be used to allow the SDN to update iptables on all nodes and stop sending traffic. (#74416, @sttts) Kubeadm now seamlessly migrates the CoreDNS Configuration when upgrading CoreDNS. (#78033, @rajansandeep)
  • Add Endpoint Slice Controller for managing new EndpointSlice resource, disabled by default. (#81048, @robscott)
  • Adds \livez for liveness health checking for kube-apiserver. Using the parameter --maximum-startup-sequence-duration will allow the liveness endpoint to defer boot-sequence failures for the specified duration period. (#81969, @logicalhan)
  • Adds EndpointSlice integration to kube-proxy, can be enabled with EndpointSlice feature gate. (#81430, @robscott)
  • Add status condition to namespace resource (#73405, @wozniakjan)
  • Enhance Azure cloud provider code to support both AAD and ADFS authentication. (#80841, @rjaini)
  • kubeadm: implement support for concurrent add/remove of stacked etcd members (#79677, @neolit123)
  • kubeadm: support any Linux kernel version newer than 3.10 (#81623, @neolit123)
  • Volume expansion is enabled in the default GCE storageclass (#78672, @msau42)
  • kubeadm ClusterConfiguration now supports featureGates: IPv6DualStack: true (#80145, @Arvinderpal)
  • In order to enable dual-stack support within kubeadm and kubernetes components, as part of the init config file, the user should set feature-gate IPv6DualStack=true in the ClusterConfiguration. Additionally, for each worker node, the user should set the feature-gate for kubelet using either nodeRegistration.kubeletExtraArgs or KUBELET_EXTRA_ARGS. (#80531, @Arvinderpal)
  • Add possibility to configure controller manager to use IPv6 dual stack: use --cluster-cidr="<cidr1>,<cidr2>". Notes:
    1. Only the first two CIDRs are used (soft limits for Alpha, might be lifted later on).
    2. Only the "RangeAllocator" (default) is allowed as a value for --cidr-allocator-type. Cloud allocators are not compatible with IPv6 dual stack (#73977, @khenidak)
  • 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)
  • When specifying --(kube|system)-reserved-cgroup, with --cgroup-driver=systemd, it is now possible to use the fully qualified cgroupfs name (i.e. /test-cgroup.slice). (#78793, @mattjmcnaughton)
  • Adds support for vSphere volumes on Windows (#80911, @gab-satchi)

API Changes

  • 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)
  • The CustomResourceDefinition API type is promoted to apiextensions.k8s.io/v1 with the following changes:
    • 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#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)

Changelog since v1.16.0-beta.1

Other notable changes

  • Fix a bug in apiserver that could cause a valid update request to be rejected with a precondition check failure. (#82303, @roycaihw)
  • Webhook client credentials configured with --admission-control-config-file must include non-default ports in the configured hostnames. For example, a webhook configured to speak to port 8443 on service mysvc in namespace myns would specify client credentials in a stanza with name: mysvc.myns.svc:8443. See https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/#authenticate-apiservers for more details. (#82252, @liggitt)
  • Ensure the KUBE-MARK-DROP chain in kube-proxy mode=ipvs. The chain is ensured for both ipv4 and ipv6 in dual-stack operation. (#82214, @uablrek)
  • kubectl cp no longer supports copying symbolic links from containers; to support this use case, see kubectl exec --help for examples using tar directly (#82143, @soltysh)
  • kubeadm: fix for HTTPProxy check for IPv6 addresses (kubernetes/kubeadm#1769) (#82267, @kad)
  • Add PodOverhead awareness to kubectl (#81929, @egernst)
  • The nbf (not before) claim, if present in ID token, is now enforced. (#81413, @anderseknert)
  • Server-side apply will now use the openapi provided in the CRD validation field to help figure out how to correctly merge objects and update ownership. (#77354, @jennybuckley)

  • Adds Endpoint Slice support for kubectl when discovery API group is enabled. (#81795, @robscott)
  • Node-Problem-Detector v0.7.1 is used for addon daemonset. (#82140, @wangzhen127)
  • aggregated discovery requests can now timeout. Aggregated apiserver must complete discovery calls within five seconds. Other requests can take longer. (#82146, @deads2k)
    • Use feature gate EnableAggregatedDiscoveryTimeout=false if you must remove this check, but that feature gate will be removed next release.
  • Graduating Windows GMSA support from alpha to beta (#82110, @wk8)
  • Add UnschedulableAndUnresolvable status code for Scheduler Framework (#82034, @alculquicondor)
  • Kubeadm now includes CoreDNS version 1.6.2 (#82127, @rajansandeep) 
    • - The CoreDNS Deployment now checks readiness via the `ready` plugin.

    • - The `proxy` plugin has been deprecated. The `forward` plugin is to be used instead.

    • - `kubernetes` plugin removes the `resyncperiod` option.

    • - The `upstream` option is deprecated and ignored if included.
  • Make kubectl get --ignore-not-found continue processing when encountering error. (#82120, @soltysh)
  • Dual stack services (Phase II of IPv6DualStack feature) are enabled via the IPVS proxier. iptables proxier does not support dualstack yet. Dualstack iptables proxier is WIP and should catchup soon. (#82091, @khenidak)
    • to enable, kube-proxy must be have the following flags:
    • --proxy-mode=ipvs
    • --cluster-cidrs=,
  • The apiserver now uses http/1.1 to communicate with admission webhooks, opening multiple connections to satisfy concurrent requests, and allowing spreading requests across multiple backing pods. (#82090, @liggitt)
  • Added support to specify a global-access annotation for gce ILB. (#81549, @prameshj)
  • Added new startupProbe, related to KEP kubernetes/enhancements#950. (#77807, @matthyx)
  • Adds \livez for liveness health checking for kube-apiserver. Using the parameter --maximum-startup-sequence-duration will allow the liveness endpoint to defer boot-sequence failures for the specified duration period. (#81969, @logicalhan)
  • Server-side apply is now Beta. (#81956, @apelisse)
  • The rejected label in apiserver_admission_webhook_admission_duration_seconds metrics now properly indicates if a request was rejected. Add a new counter metrics apiserver_admission_webhook_rejection_count with details about the causing for a webhook rejection. (#81399, @roycaihw)
  • Add container_state label to running_container_count kubelet metrics, to get count of containers based on their state(running/exited/created/unknown) (#81573, @irajdeep)
  • Fix a bug in CRD openapi controller that user-defined CRD can overwrite OpenAPI definition/path for the CRD API. (#81436, @roycaihw)
  • Service account tokens now include the JWT Key ID field in their header. (#78502, @ahmedtd)
  • Adds EndpointSlice integration to kube-proxy, can be enabled with EndpointSlice feature gate. (#81430, @robscott)
  • Azure supports IPv6 only on ELB not ILB. The cloud provider will return an error if the service is internal and is IPv6. (#80485, @khenidak)
    • Notes on LB name:
    • to ensure backword and forward compat:
      • SingleStack -v4 (pre v1.16) => BackendPool name == clusterName
      • SingleStack -v6 => BackendPool name == clusterName (all cluster bootstrap uses this name)
    • DualStack:
    • => IPv4 BackendPool name == clusterName
    • => IPv6 BackendPool name == -IPv6
    • This result into:
      • clusters moving from IPv4 to duakstack will require no changes
      • clusters moving from IPv6 (while not seen in the wild, we can not rule out their existence) to dualstack will require deleting backend pools (the reconciler will take care of creating correct backendpools)
  • Promotes VolumePVCDataSource (Cloning) feature to beta for 1.16 release (#81792, @j-griffith)
  • Remove kubectl log, use kubectl logs instead (#78098, @soltysh)
  • CSI ephemeral inline volume support is beta, i.e. the CSIInlineVolume feature gate is enabled by default (#82004, @pohly)
  • kubectl: the --all-namespaces flag is now honored by kubectl wait (#81468, @ashutoshgngwr)
  • Kube-proxy metrics are now marked as with the ALPHA stability level. (#81626, @logicalhan)
  • Kube-controller-manager and cloud-controller-manager metrics are now marked as with the ALPHA stability level. (#81624, @logicalhan)
  • Adds Endpoint Slice Controller for managing new EndpointSlice resource, disabled by default. (#81048, @robscott)
    • to run: (#79386, @khenidak)
      • Master: convert service CIDR to list --service-cluster-ip-range=<CIDR>,<CIDR> and make sure IPv6DualStack feature flag is turned on. The flag is validated and used as the following:
        1. --service-cluster-ip-range[0] is consider primary service range, and will be used for any service with Service.Spec.IPFamily = nil or any service in the at the time of turning on the feature flag.
        1. A cluster can be dualstack (i.e. Pods and nodes carry dualstack IPs) but does not need to support ingress on dualstack. In this case the cluster can perform egress using PodIPs (according to family and binding selection in user code) but will ingress will only be performed against the pod primary IP. This can be configured by supplying single entry to --service-cluster-ip-range flag.
        1. Maximum of two entries is allowed in --service-cluster-ip-range and they are validated to be dual stacked i.e. --service-cluster-ip-range=<v4>,<v6> or --service-cluster-ip-range=<v6>,<v4>
        1. Max 20 bit for range (min network bits <v6>/108 or /12)
      • kube-controller-manager: convert service CIDR to list --service-cluster-ip-range=<CIDR>,<CIDR> and make sure IPv6DualStack feature flag is turned on. The flag is validated as above.
        • to use:
      • A new service spec field Service.Spec.IPFamily has been added. The default of this field is family of (first service cidr in --service-cluster-ip-range flag). The value is defaulted as described above once the feature gate is turned on. Here are the possible values for this field:
        1. IPv4: api-server will assign an IP from a service-cluster-ip-range that is ipv4 (either the primary or the secondary, according to how they were configured).
        1. IPv6: api-server will assign an IP from a service-cluster-ip-range that is ipv6 (either the primary or the secondary, according to how they were configured).
      • Notes (v1.16):
        1. IPVS is the only proxy supported (as of v1.16 ) by Dualstack.
        1. Dualstack is mutually exclusive with EndpointSlice feature. They can not be turned on together. metaproxy is yet to implement EndpointSlice handling.
  • Kubelet metrics for /metrics and /metrics/probes are now marked as with the ALPHA stability level. (#81534, @logicalhan)
  • Added metrics 'authentication_attempts' that can be used to understand the attempts of authentication. (#81509, @RainbowMango)
  • Fix in kube-proxy for SCTP nodeport service which only works for node's InternalIP, but doesn't work for other IPs present in the node when ipvs is enabled. (#81477, @paulsubrata55)
  • The CustomResourceValidation, CustomResourceSubresources, CustomResourceWebhookConversion and CustomResourcePublishOpenAPI features are now GA, and the associated feature gates deprecated and will be removed in v1.18. (#81965, @roycaihw)
  • Node-Problem-Detector v0.7.1 is used on GCI. (#80726, @wangzhen127)
  • kubeadm: prevent overriding of certain kubelet security configuration parameters if the user wished to modify them (#81903, @jfbai)
  • Introduce node.kubernetes.io/exclude-balancer and node.kubernetes.io/exclude-disruption labels in alpha to prevent cluster deployers from being dependent on the optional node-role labels which not all clusters may provide. (#80238, @smarterclayton)
  • Scheduler metrics are now marked as with the ALPHA stability level. (#81576, @logicalhan)
  • cache-control headers are now set appropriately. Only openapi is cacheable if etags match. (#81946, @deads2k)
  • Added E2E tests validating WindowsOptions.RunAsUserName. (#79539, @bclau)
  • Kube-apiserver metrics are now marked as with the ALPHA stability level. (#81531, @logicalhan)
  • Move CSI volume expansion to beta. (#81467, @bertinatto)
  • Support Kubelet plugin watcher on Windows nodes. (#81397, @ddebroy)
  • Updates the requestedToCapacityRatioArguments to add resources parameter that allows the users to specify the resource name along with weights for each resource to score nodes based on the request to capacity ratio. (#77688, @sudeshsh)
  • Finalizer Protection for Service LoadBalancers is now in Beta (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted. (#81691, @MrHohn)
  • Adds support for vSphere volumes on Windows (#80911, @gab-satchi)
  • Log when kube-apiserver regenerates the OpenAPI spec and why. OpenAPI spec generation is a very CPU-heavy process that is sensitive to continuous updates of CRDs and APIServices. (#81786, @sttts)
    • Added metrics aggregator_openapi_v2_regeneration_count, aggregator_openapi_v2_regeneration_gauge and apiextension_openapi_v2_regeneration_count metrics counting the triggering APIService and CRDs and the reason (add, update, delete).
  • Fix an issue with toleration merging & whitelist checking in the PodTolerationRestriction admission controller. (#81732, @tallclair)
  • Add a helper function to decode scheduler plugin args. (#80696, @hex108)
  • Add metadata.generation=1 to old CustomResources. (#82005, @sttts)
  • kubeadm no longer performs IPVS checks as part of its preflight checks (#81791, @yastij)
  • The RemainingItemCount feature is now beta. (#81682, @caesarxuchao)
    • remainingItemCount is the number of subsequent items in the list which are not included in this list response. If the list request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. If the list is complete (either because it is not chunking or because this is the last chunk), then there are no more remaining items and this field will be left unset and omitted during serialization. Servers older than v1.15 do not set this field. The intended use of the remainingItemCount is estimating the size of a collection. Clients should not rely on the remainingItemCount to be set or to be exact.
  • The CustomResourceDefaulting feature is promoted to beta and enabled by default. Defaults may be specified in structural schemas via the apiextensions.k8s.io/v1 API. See https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/#specifying-a-structural-schema for details. (#81872, @sttts)
  • kubectl could scale custom resource again (#81342, @knight42)
  • a CSI driver that supports ephemeral inline volumes must explicitly declare that by providing a CSIDriver object where the new "mode" field is set to "ephemeral" or "persistent+ephemeral" (#80568, @pohly)
  • framework.ExpectNoError no longer logs the error and instead relies on using the new log.Fail as Gomega fail handler. (#80253, @pohly)
  • Audit events now log the existence and patch of mutating webhooks. (#77824, @roycaihw) * At Metadata audit level or higher, an annotation with key "mutation.webhook.admission.k8s.io/round_{round idx}index{order idx}" gets logged with JSON payload indicating a webhook gets invoked for given request and whether it mutated the object or not. * At Request audit level or higher, an annotation with key "patch.webhook.admission.k8s.io/round_{round idx}index{order idx}" get logged with the JSON payload logging the patch sent by a webhook for given request.
  • Resolves an issue that prevented block volumes from being resized. (#81429, @huffmanca)
  • Verify that CRD default values in OpenAPI specs are pruned, with the exceptions of values under metadata. (#78829, @sttts)
  • Use PostFilter instead of Postfilter in the scheduling framework (#81800, @draveness)
    • Use PreFilter instead of Prefilter in the scheduling framework
    • Use PreBind instead of Prebind in the scheduling framework
  • Fix kubectl logs -f for windows server containers. (#81747, @Random-Liu)
  • fix azure disk naming matching issue due to case sensitive comparison (#81720, @andyzhangx)
  • Fixes a bug that when there is a "connection refused" error, the reflector's ListAndWatch func will return directly but what expected is that sleep 1 second and rewatch since the specified resourceVersion. (#81634, @likakuli)
  • Fixed a bug with the openAPI definition for io.k8s.apimachinery.pkg.runtime.RawExtension, which previously required a field "raw" to be specified (#80773, @jennybuckley)
  • kubeadm: print the stack trace of an error for klog level --v>=5 (#80937, @neolit123)
  • Fixes a problem with the iptables proxy mode that could result in long delays (#80368, @danwinship)
    • updating Service/Endpoints IPs in very large clusters on RHEL/CentOS 7.
  • kubeadm: support any Linux kernel version newer than 3.10 (#81623, @neolit123)

Changelog since v1.16.0-alpha.2

Action Required

  • ACTION REQUIRED: (#80676, @fabriziopandini)
    • kubeadm now deletes the bootstrap-kubelet.conf file after TLS bootstrap
    • User relying on bootstrap-kubelet.conf should switch to kubelet.conf that contains node credentials

Other notable changes

  • Fixes validation of VolumeAttachment API objects created with inline volume sources. (#80945, @tedyu)
  • Azure disks of shared kind will no longer fail if they do not contain skuname or (#80837, @rmweir) 
    • storageaccounttype.
  • kubeadm: fix "certificate-authority" files not being pre-loaded when using file discovery (#80966, @neolit123)
  • Errors from pod volume set up are now propagated as pod events. (#80369, @jsafrane)
  • kubeadm: enable secure serving for the kube-scheduler (#80951, @neolit123)
  • Kubernetes client users may disable automatic compression when invoking Kubernetes APIs by setting the DisableCompression field on their rest.Config. This is recommended when clients communicate primarily over high bandwidth / low latency networks where response compression does not improve end to end latency. (#80919, @smarterclayton)
  • kubectl get did not correctly count the number of binaryData keys when listing config maps. (#80827, @smarterclayton)
  • Implement "post-filter" extension point for scheduling framework (#78097, @draveness)
  • Reduces GCE PD Node Attach Limits by 1 since the node boot disk is considered an attachable disk (#80923, @davidz627)
  • This PR fixes an error when using external etcd but storing etcd certificates in the same folder and with the same name used by kubeadm for local etcd certificates; for an older version of kubeadm, the workaround is to avoid file name used by kubeadm for local etcd. (#80867, @fabriziopandini)
  • When specifying --(kube|system)-reserved-cgroup, with --cgroup-driver=systemd, it is now possible to use the fully qualified cgroupfs name (i.e. /test-cgroup.slice). (#78793, @mattjmcnaughton)
  • kubeadm: treat non-fatal errors as warnings when doing reset (#80862, @drpaneas)
  • kube-addon-manager has been updated to v9.0.2 to fix a bug in leader election (kubernetes#80575) (#80861, @mborsz)
  • Determine system model to get credentials for windows nodes. (#80764, @liyanhui1228)
  • TBD (#80730, @jennybuckley)
  • 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: (#80231, @liggitt) * 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)
  • "kubeadm join" fails if file-based discovery is too long, with a default timeout of 5 minutes. (#80804, @olivierlemasle)
  • enhance Azure cloud provider code to support both AAD and ADFS authentication. (#80841, @rjaini)
  • Attempt to set the kubelet's hostname & internal IP if --cloud-provider=external and no node addresses exists (#75229, @andrewsykim)
  • kubeadm: avoid double deletion of the upgrade prepull DaemonSet (#80798, @xlgao-zju)
  • Fixes problems with connecting to services on localhost on some systems; in particular, DNS queries to systemd-resolved on Ubuntu. (#80591, @danwinship)
  • Implement normalize plugin extension point for the scheduler framework. (#80383, @liu-cong)
  • Fixed the bash completion error with override flags. (#80802, @dtaniwaki)
  • Fix CVE-2019-11247: API server allows access to custom resources via wrong scope (#80750, @sttts)
  • Failed iscsi logout is now re-tried periodically. (#78941, @jsafrane)
  • Fix public IP not found issues for VMSS nodes (#80703, @feiskyer)
  • In order to enable dual-stack support within kubeadm and kubernetes components, as part of the init config file, the user should set feature-gate IPv6DualStack=true in the ClusterConfiguration. Additionally, for each worker node, the user should set the feature-gate for kubelet using either nodeRegistration.kubeletExtraArgs or KUBELET_EXTRA_ARGS. (#80531, @Arvinderpal)
  • Fix error in kubeadm join --discovery-file when using discovery files with embedded credentials (#80675, @fabriziopandini)

Changelog since v1.15.0

Action Required

  • Migrate scheduler to use v1beta1 Event API. action required: any tool targeting scheduler events needs to use v1beta1 Event API (#78447, @yastij)
  • scheduler.alpha.kubernetes.io/critical-pod annotation is removed. Pod priority (spec.priorityClassName) should be used instead to mark pods as critical. Action required! (#79554, @draveness)
  • hyperkube: the --make-symlinks flag, deprecated in v1.14, has been removed. (#80017, @Pothulapati)
  • Node labels beta.kubernetes.io/metadata-proxy-ready, beta.kubernetes.io/metadata-proxy-ready and beta.kubernetes.io/kube-proxy-ds-ready are no longer added on new nodes. (#79305, @paivagustavo) * ip-mask-agent addon starts to use the label node.kubernetes.io/masq-agent-ds-ready instead of beta.kubernetes.io/masq-agent-ds-ready as its node selector. * kube-proxy addon starts to use the label node.kubernetes.io/kube-proxy-ds-ready instead of beta.kubernetes.io/kube-proxy-ds-ready as its node selector. * metadata-proxy addon starts to use the label cloud.google.com/metadata-proxy-ready instead of beta.kubernetes.io/metadata-proxy-ready as its node selector. * Kubelet removes the ability to set kubernetes.io or k8s.io labels via --node-labels other than the specifically allowed labels/prefixes.
  • The following APIs are no longer served by default: (#70672, @liggitt) * All resources under apps/v1beta1 and apps/v1beta2 - use apps/v1 instead * daemonsets, deployments, replicasets resources under extensions/v1beta1 - use apps/v1 instead * networkpolicies resources under extensions/v1beta1 - use networking.k8s.io/v1 instead * podsecuritypolicies resources under extensions/v1beta1 - use policy/v1beta1 instead
    • Serving these resources can be temporarily re-enabled using the --runtime-config apiserver flag.
      • apps/v1beta1=true
      • apps/v1beta2=true
      • extensions/v1beta1/daemonsets=true,extensions/v1beta1/deployments=true,extensions/v1beta1/replicasets=true,extensions/v1beta1/networkpolicies=true,extensions/v1beta1/podsecuritypolicies=true
    • The ability to serve these resources will be completely removed in v1.18.
  • ACTION REQUIRED: Removed deprecated flag --resource-container from kube-proxy. (#78294, @vllry)
    • The deprecated --resource-container flag has been removed from kube-proxy, and specifying it will now cause an error. The behavior is now as if you specified --resource-container="". If you previously specified a non-empty --resource-container, you can no longer do so as of kubernetes 1.16.

Other notable changes

  • When HPAScaleToZero feature gate is enabled HPA supports scaling to zero pods based on object or external metrics. HPA remains active as long as at least one metric value available. (#74526, @DXist)
    • To downgrade the cluster to version that does not support scale-to-zero feature:
      1. make sure there are no hpa objects with minReplicas=0. Here is a oneliner to update it to 1:
    • $ kubectl get hpa --all-namespaces  --no-headers=true | awk  '{if($6==0) printf "kubectl patch hpa/%s --namespace=%s -p \"{\\"spec\\":{\\"minReplicas\\":1}}\"

", $2, $1 }' | sh * 2. disable HPAScaleToZero feature gate

  • Add support for writing out of tree custom scheduler plugins. (#78162, @hex108)
  • Remove deprecated github.com/kardianos/osext dependency (#80142, @loqutus)
  • Add Bind extension point to the scheduling framework. (#79313, @chenchun)
  • On Windows systems, %USERPROFILE% is now preferred over %HOMEDRIVE%%HOMEPATH% as the home folder if %HOMEDRIVE%%HOMEPATH% does not contain a .kube* Add --kubernetes-version to "kubeadm init phase certs ca" and "kubeadm init phase kubeconfig" (#80115, @gyuho)
  • kubeadm ClusterConfiguration now supports featureGates: IPv6DualStack: true (#80145, @Arvinderpal)
  • Fix a bug that ListOptions.AllowWatchBookmarks wasn't propagating correctly in kube-apiserver. (#80157, @wojtek-t)
  • Bugfix: csi plugin supporting raw block that does not need attach mounted failed (#79920, @cwdsuzhou)
  • Increase log level for graceful termination to v=5 (#80100, @andrewsykim)
  • kubeadm: support fetching configuration from the original cluster for 'upgrade diff' (#80025, @SataQiu)
  • The sample-apiserver gains support for OpenAPI v2 spec serving at /openapi/v2. (#79843, @sttts)
    • The generate-internal-groups.sh script in k8s.io/code-generator will generate OpenAPI definitions by default in pkg/generated/openapi. Additional API group dependencies can be added via OPENAPI_EXTRA_PACKAGES=<group>/<version> <group2>/<version2>....
  • Cinder and ScaleIO volume providers have been deprecated and will be removed in a future release. (#80099, @dims)
  • kubelet's --containerized flag was deprecated in 1.14. This flag is removed in 1.16. (#80043, @dims)
  • Optimize EC2 DescribeInstances API calls in aws cloud provider library by querying instance ID instead of EC2 filters when possible (#78140, @zhan849)
  • etcd migration image no longer supports etcd2 version. (#80037, @dims)
  • Promote WatchBookmark feature to beta and enable it by default. (#79786, @wojtek-t)
    • With WatchBookmark feature, clients are able to request watch events with BOOKMARK type. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session.
  • update to use go 1.12.7 (#79966, @tao12345666333)
  • Add --shutdown-delay-duration to kube-apiserver in order to delay a graceful shutdown. /healthz will keep returning success during this time and requests are normally served, but /readyz will return faillure immediately. This delay can be used to allow the SDN to update iptables on all nodes and stop sending traffic. (#74416, @sttts)
  • The MutatingWebhookConfiguration and ValidatingWebhookConfiguration APIs have been promoted to admissionregistration.k8s.io/v1: (#79549, @liggitt) * 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 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 admissionregistration.k8s.io/v1beta1 versions of MutatingWebhookConfiguration and ValidatingWebhookConfiguration are deprecated and will no longer be served in v1.19.
  • The garbage collector and generic object quota controller have been updated to use the metadata client which improves memory (#78742, @smarterclayton)
    • and CPU usage of the Kube controller manager.
  • SubjectAccessReview requests sent for RBAC escalation, impersonation, and pod security policy authorization checks now populate the version attribute. (#80007, @liggitt)
  • na (#79892, @mikebrow)
  • Use O_CLOEXEC to ensure file descriptors do not leak to subprocesses. (#74691, @cpuguy83)
  • The namespace controller has been updated to use the metadata client which improves memory (#78744, @smarterclayton)
    • and CPU usage of the Kube controller manager.
  • add kubectl replace --raw and kubectl delete --raw to have parity with create and get (#79724, @deads2k)
  • E2E tests no longer add command line flags directly to the command line, test suites that want that need to be updated if they don't use HandleFlags (#75593, @pohly)
    • loading a -viper-config=e2e.yaml with suffix (introduced in 1.13) works again and now has a regression test
  • Kubernetes now supports transparent compression of API responses. Clients that send Accept-Encoding: gzip will now receive a GZIP compressed response body if the API call was larger than 128KB. Go clients automatically request gzip-encoding by default and should see reduced transfer times for very large API requests. Clients in other languages may need to make changes to benefit from compression. (#77449, @smarterclayton)
  • Resolves an issue serving aggregated APIs backed by services that respond to requests to / with non-2xx HTTP responses (#79895, @deads2k)
  • updated fluentd to 1.5.1, elasticsearchs & kibana to 7.1.1 (#79014, @monotek)
  • kubeadm: implement support for concurrent add/remove of stacked etcd members (#79677, @neolit123)
  • Added a metric 'apiserver_watch_events_total' that can be used to understand the number of watch events in the system. (#78732, @mborsz)
  • KMS Providers will install a healthz check for the status of kms-pluign in kube-apiservers' encryption config. (#78540, @immutableT)
  • Fixes a bug in openapi published for custom resources using x-kubernetes-preserve-unknown-fields extensions, so that kubectl will allow sending unknown fields for that portion of the object. (#79636, @liggitt)
  • A new client k8s.io/client-go/metadata.Client has been added for accessing objects generically. This client makes it easier to retrieve only the metadata (the metadata sub-section) from resources on the cluster in an efficient manner for use cases that deal with objects generically, like the garbage collector, quota, or the namespace controller. The client asks the server to return a meta.k8s.io/v1 PartialObjectMetadata object for list, get, delete, watch, and patch operations on both normal APIs and custom resources which can be encoded in protobuf for additional work. If the server does not yet support this API the client will gracefully fall back to JSON and transform the response objects into PartialObjectMetadata. (#77819, @smarterclayton)
  • changes timeout value in csi plugin from 15s to 2min which fixes the timeout issue (#79529, @andyzhangx)
  • kubeadm: provide "--control-plane-endpoint" flag for controlPlaneEndpoint (#79270, @SataQiu)
  • Fixes invalid "time stamp is the future" error when kubectl cp-ing a file (#73982, @tanshanshan)
  • 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)
  • To configure controller manager to use ipv6dual stack: (#73977, @khenidak)

    • use --cluster-cidr=",".

    • Notes:

      1. Only the first two cidrs are used (soft limits for Alpha, might be lifted later on).
      1. Only the "RangeAllocator" (default) is allowed as a value for --cidr-allocator-type . Cloud allocators are not compatible with ipv6dualstack
  • When using the conformance test image, a new environment variable E2E_USE_GO_RUNNER will cause the tests to be run with the new Golang-based test runner rather than the current bash wrapper. (#79284, @johnSchnake)
  • kubeadm: prevent PSP blocking of upgrade image prepull by using a non-root user (#77792, @neolit123)
  • kubelet now accepts a --cni-cache-dir option, which defaults to /var/lib/cni/cache, where CNI stores cache files. (#78908, @dcbw)
  • Update Azure API versions (containerregistry --> 2018-09-01, network --> 2018-08-01) (#79583, @justaugustus)
  • Fix possible fd leak and closing of dirs in doSafeMakeDir (#79534, @odinuge)
  • kubeadm: fix the bug that "--cri-socket" flag does not work for kubeadm reset (#79498, @SataQiu)

  • Fix duplicate error messages in cli commands (#79493, @odinuge)
  • Default resourceGroup should be used when the value of annotation azure-load-balancer-resource-group is an empty string. (#79514, @feiskyer)
  • Fixes output of kubectl get --watch-only when watching a single resource (#79345, @liggitt)
  • RateLimiter add a context-aware method, fix client-go request goruntine backlog in async timeout scene. (#79375, @answer1991)
  • Fix a bug where kubelet would not retry pod sandbox creation when the restart policy of the pod is Never (#79451, @yujuhong)
  • Fix CRD validation error on 'items' field. (#76124, @tossmilestone)
  • The CRD handler now properly re-creates stale CR storage to reflect CRD update. (#79114, @roycaihw)
  • Integrated volume limits for in-tree and CSI volumes into one scheduler predicate. (#77595, @bertinatto)
  • Fix a bug in server printer that could cause kube-apiserver to panic. (#79349, @roycaihw)
  • Mounts /home/kubernetes/bin/nvidia/vulkan/icd.d on the host to /etc/vulkan/icd.d inside containers requesting GPU. (#78868, @chardch)
  • Remove CSIPersistentVolume feature gates (#79309, @draveness)
  • Init container resource requests now impact pod QoS class (#75223, @sjenning)
  • Correct the maximum allowed insecure bind port for the kube-scheduler and kube-apiserver to 65535. (#79346, @ncdc)

  • Remove KubeletPluginsWatcher feature gates (#79310, @draveness)
  • Remove HugePages, VolumeScheduling, CustomPodDNS and PodReadinessGates feature flags (#79307, @draveness)
  • The GA PodPriority feature gate is now on by default and cannot be disabled. The feature gate will be removed in v1.18. (#79262, @draveness)
  • Remove pids cgroup controller requirement when related feature gates are disabled (#79073, @rafatio)
  • Add Bind extension point of the scheduling framework (#78513, @chenchun)
  • if targetPort is changed that will process by service controller (#77712, @Sn0rt)
  • update to use go 1.12.6 (#78958, @tao12345666333)
  • kubeadm: fix a potential panic if kubeadm discovers an invalid, existing kubeconfig file (#79165, @neolit123)
  • fix kubelet fail to delete orphaned pod directory when the kubelet's pods directory (default is "/var/lib/kubelet/pods") symbolically links to another disk device's directory (#79094, @gaorong)
  • Addition of Overhead field to the PodSpec and RuntimeClass types as part of the Pod Overhead KEP (#76968, @egernst)
  • fix pod list return value of framework.WaitForPodsWithLabelRunningReady (#78687, @pohly)
  • The behavior of the default handler for 404 requests fro the GCE Ingress load balancer is slightly modified in the sense that it now exports metrics using prometheus. The metrics exported include: (#79106, @vbannai)
      • http_404_request_total (the number of 404 requests handled)
      • http_404_request_duration_ms (the amount of time the server took to respond in ms)
    • Also includes percentile groupings. The directory for the default 404 handler includes instructions on how to enable prometheus for monitoring and setting alerts.
  • The kube-apiserver has improved behavior for both startup and shutdown sequences and also now exposes /readyz for readiness checking. Readyz includes all existing healthz checks but also adds a shutdown check. When a cluster admin initiates a shutdown, the kube-apiserver will try to process existing requests (for the duration of request timeout) before killing the apiserver process. (#78458, @logicalhan)
    • The apiserver also now takes an optional flag "--maximum-startup-sequence-duration". This allows you to explicitly define an upper bound on the apiserver startup sequences before healthz begins to fail. By keeping the kubelet liveness initial delay short, this can enable quick kubelet recovery as soon as we have a boot sequence which has not completed in our expected time frame, despite lack of completion from longer boot sequences (like RBAC). Kube-apiserver behavior when the value of this flag is zero is backwards compatible (this is as the defaulted value of the flag).
  • fix: make azure disk URI as case insensitive (#79020, @andyzhangx)
  • Enable cadvisor ProcessMetrics collecting. (#79002, @jiayingz)
  • Fixes a bug where kubectl set config hangs and uses 100% CPU on some invalid property names (#79000, @pswica)
