Changelog since v1.12.0-alpha.1

Action Required

  • Move volume dynamic provisioning scheduling to beta (ACTION REQUIRED: The DynamicProvisioningScheduling alpha feature gate has been removed. The VolumeScheduling beta feature gate is still required for this feature) (#67432, @lichuqiang)

Other notable changes

  • Not split nodes when searching for nodes but doing it all at once. (#67555, @wgliang)
  • Deprecate kubectl run generators, except for run-pod/v1 (#68132, @soltysh)
  • Using the Horizontal Pod Autoscaler with metrics from Heapster is now deprecated. (#68089, @DirectXMan12)
  • Support both directory and block device for local volume plugin FileSystem VolumeMode (#63011, @NickrenREN)
  • Add CSI volume attributes for kubectl describe pv. (#65074, @wgliang)
  • kubectl rollout status now works for unlimited timeouts. (#67817, @tnozicka)
  • Fix panic when processing Azure HTTP response. (#68210, @feiskyer)
  • add mixed protocol support for azure load balancer (#67986, @andyzhangx)
  • Replace scale down forbidden window with scale down stabilization window. Rather than waiting a fixed period of time between scale downs HPA now scales down to the highest recommendation it during the scale down stabilization window. (#68122, @krzysztof-jastrzebski)
  • Adding validation to kube-scheduler at the API level (#66799, @noqcks)
  • Improve performance of Pod affinity/anti-affinity in the scheduler (#67788, @ahmad-diaa)
  • kubeadm: fix air-gapped support and also allow some kubeadm commands to work without an available networking interface (#67397, @neolit123)
  • Increase Horizontal Pod Autoscaler default update interval (30s -> 15s). It will improve HPA reaction time for metric changes. (#68021, @krzysztof-jastrzebski)
  • Increase scrape frequency of metrics-server to 30s (#68127, @serathius)
  • Add new --server-dry-run flag to kubectl apply so that the request will be sent to the server with the dry-run flag (alpha), which means that changes won't be persisted. (#68069, @apelisse)
  • kubelet v1beta1 external ComponentConfig types are now available in the k8s.io/kubelet repo (#67263, @luxas)
  • Adds a kubelet parameter and config option to change CFS quota period from the default 100ms to some other value between 1µs and 1s. This was done to improve response latencies for workloads running in clusters with guaranteed and burstable QoS classes. (#63437, @szuecs)
  • Enable secure serving on port 10258 to cloud-controller-manager (configurable via --secure-port). Delegated authentication and authorization have to be configured like for aggregated API servers. (#67069, @sttts)
  • Support extra --prune-whitelist resources in kube-addon-manager. (#67743, @Random-Liu)
  • 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. (#67284, @caesarxuchao)
  • Role, ClusterRole and their bindings for cloud-provider is put under system namespace. Their addonmanager mode switches to EnsureExists. (#67224, @grayluck)
  • Mount propagation has promoted to GA. The MountPropagation feature gate is deprecated and will be removed in 1.13. (#67255, @bertinatto)
  • Introduce CSI Cluster Registration mechanism to ease CSI plugin discovery and allow CSI drivers to customize Kubernetes' interaction with them. (#67803, @saad-ali)
  • Adds the commands kubeadm alpha phases renew <cert-name> (#67910, @liztio)
  • ProcMount added to SecurityContext and AllowedProcMounts added to PodSecurityPolicy to allow paths in the container's /proc to not be masked. (#64283, @jessfraz)

  • CoreDNS is now v1.2.2 for Kubernetes 1.12 (#68076, @rajansandeep)
  • Enable secure serving on port 10257 to kube-controller-manager (configurable via --secure-port). Delegated authentication and authorization have to be configured like for aggregated API servers. (#64149, @sttts)
  • Update metrics-server to v0.3.0. (#68077, @DirectXMan12)
  • TokenRequest and TokenRequestProjection are now beta features. To enable these feature, the API server needs to be started with the following flags: (#67349, @mikedanese) * --service-account-issuer * --service-account-signing-key-file * --service-account-api-audiences
  • Don't let aggregated apiservers fail to launch if the external-apiserver-authentication configmap is not found in the cluster. (#67836, @sttts)
  • Promote AdvancedAuditing to GA, replacing the previous (legacy) audit logging mechanisms. (#65862, @loburm)
  • Azure cloud provider now supports unmanaged nodes (such as on-prem) that are labeled with kubernetes.azure.com/managed=false and alpha.service-controller.kubernetes.io/exclude-balancer=true (#67984, @feiskyer)
  • kubectl get apiservice now shows the target service and whether the service is available (#67747, @smarterclayton)

  • Added support to restore a volume from a volume snapshot data source. (#67087, @xing-yang)
  • fixes the errors/warnings in fluentd configuration (#67947, @saravanan30erd)
  • Stop counting soft-deleted pods for scaling purposes in HPA controller to avoid soft-deleted pods incorrectly affecting scale up replica count calculation. (#67067, @moonek)
  • delegated authn/z: optionally opt-out of mandatory authn/authz kubeconfig (#67545, @sttts)
  • kubeadm: Control plane images (etcd, kube-apiserver, kube-proxy, etc.) don't use arch suffixes. Arch suffixes are kept for kube-dns only. (#66960, @rosti)
  • Adds sample-cli-plugin staging repository (#67938, @soltysh)
  • adjusted http/2 buffer sizes for apiservers to prevent starvation issues between concurrent streams (#67902, @liggitt)

      • Change chain name to IP-MASQ to be compatible with the
    • pre-injected masquerade rules.
  • AllowedTopologies field inside StorageClass is now validated against set and map semantics. Specifically, there cannot be duplicate TopologySelectorTerms, MatchLabelExpressions keys, and TopologySelectorLabelRequirement Values. (#66843, @verult)
  • 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. (#64097, @damemi)
  • The cloudstack cloud provider now reports a Hostname address type for nodes based on the local-hostname metadata key. (#67719, @liggitt)
  • kubeadm: --cri-socket now defaults to tcp://localhost:2375 when running on Windows (#67447, @benmoss)
  • kubeadm: The kubeadm configuration now support definition of more than one control plane instances with their own APIEndpoint. The APIEndpoint for the "bootstrap" control plane instance should be defined using InitConfiguration.APIEndpoint, while the APIEndpoints for additional control plane instances should be added using JoinConfiguration.APIEndpoint. (#67832, @fabriziopandini)
  • Enable dynamic azure disk volume limits (#67772, @andyzhangx)
  • kubelet: Users can now enable the alpha NodeLease feature gate to have the Kubelet create and periodically renew a Lease in the kube-node-lease namespace.

  • Replace scale up forbidden window with disregarding CPU samples collected when pod was initializing. (#67252, @jbartosik)
  • Moving KubeSchedulerConfiguration from ComponentConfig API types to staging repos (#66916, @dixudx)
  • Improved error message when checking the rollout status of StatefulSet with OnDelete strategy type (#66983, @mortent)
  • RuntimeClass is a new API resource for defining different classes of runtimes that may be used to run containers in the cluster. 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. (#67737, @tallclair)

  • kubectl create secret tls can now read certificate and key files from process substitution arguments (#67713, @liggitt)
  • change default value of kind for azure disk (#67483, @andyzhangx)
  • 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. (#66936, @jennybuckley)
  • Kubeadm ha upgrade (#66973, @fabriziopandini)
  • kubeadm: InitConfiguration now consists of two structs: InitConfiguration and ClusterConfiguration (#67441, @rosti)
  • Updated Cluster Autoscaler version to 1.3.2-beta.2. Release notes: https://github.com/kubernetes/autoscaler/releases/tag/cluster-autoscaler-1.3.2-beta.2 (#67697, @aleksandra-malinowska)
  • cpumanager: rollback state if updateContainerCPUSet failed (#67430, @choury)

  • add --dns-loop-detect option to dnsmasq run by kube-dns (#67302, @dixudx)
  • Switched certificate data replacement from "REDACTED" to "DATA+OMITTED" (#66023, @ibrasho)
  • improve performance of anti-affinity predicate of default scheduler. (#66948, @mohamed-mehany)
  • Fixed a bug that was blocking extensible error handling when serializing API responses error out. Previously, serialization failures always resulted in the status code of the original response being returned. Now, the following behavior occurs: (#67041, @tristanburgess)
      • If the serialization type is application/vnd.kubernetes.protobuf, and protobuf marshaling is not implemented for the requested API resource type, a '406 Not Acceptable is returned'.
      • If the serialization type is 'application/json':
    •     - If serialization fails, and the original status code was an failure (e.g. 4xx or 5xx), the original status code will be returned.

    •     - If serialization fails, and the original status code was not a failure (e.g. 2xx), the status code of the serialization failure will be returned. By default, this is '500 Internal Server Error', because JSON serialization is our default, and not supposed to be implemented on a type-by-type basis.
  • Add a feature to the scheduler to score fewer than all nodes in every scheduling cycle. This can improve performance of the scheduler in large clusters. (#66733, @bsalamat)
  • kube-controller-manager can now start the quota controller when discovery results can only be partially determined. (#67433, @deads2k)
  • The plugin mechanism functionality now closely follows the git plugin design (#66876, @juanvallejo)
  • GCE: decrease cpu requests on master node, to allow more components to fit on one core machine. (#67504, @loburm)
  • PVC may not be synced to controller local cache in time if PV is bound by external PV binder (e.g. kube-scheduler), double check if PVC is not found to prevent reclaiming PV wrongly. (#67062, @cofyc)
  • add more storage account sku support for azure disk (#67528, @andyzhangx)
  • updates es-image to elasticsearch 6.3.2 (#67484, @monotek)

  • The dockershim now sets the "bandwidth" and "ipRanges" CNI capabilities (dynamic parameters). Plugin authors and administrators can now take advantage of this by updating their CNI configuration file. For more information, see the CNI docs (#64445, @squeed)
  • Expose /debug/flags/v to allow kubelet dynamically set glog logging level. If want to change glog level to 3, you only have to send a PUT request like curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3". (#64601, @hzxuzhonghu)
  • Fix an issue that pods using hostNetwork keep increasing. (#67456, @Huang-Wei)
  • DaemonSet controller is now using backoff algorithm to avoid hot loops fighting with kubelet on pod recreation when a particular DaemonSet is misconfigured. (#65309, @tnozicka)

  • Remove unused binary and container image for kube-aggregator. The functionality is already integrated into the kube-apiserver. (#67157, @dims)
  • Avoid creating new controller revisions for statefulsets when cache is stale (#67039, @mortent)
  • Revert #63905: Setup dns servers and search domains for Windows Pods. DNS for Windows containers will be set by CNI plugins. (#66587, @feiskyer)

  • fix azure disk create failure due to sdk upgrade (#67236, @andyzhangx)
  • Kubeadm join --control-plane main workflow (#66873, @fabriziopandini)
  • Dynamic provisions that create iSCSI PVs can ensure that multipath is used by specifying 2 or more target portals in the PV, which will cause kubelet to wait up to 10 seconds for the multipath device. PVs with just one portal continue to work as before, with kubelet not waiting for the multipath device and just using the first disk it finds. (#67140, @bswartz)
  • kubectl: recreating resources for immutable fields when force is applied (#66602, @dixudx)
  • Remove deprecated --interactive flag from kubectl logs. (#65420, @jsoref)
  • kubeadm uses audit policy v1 instead of v1beta1 (#67176, @charrywanganthony)

    • Also updates dependencies of users of debian-base.
    • debian-base version 0.3.1 is already available.
  • DynamicProvisioningScheduling and VolumeScheduling is now supported for Azure managed disks. Feature gates DynamicProvisioningScheduling and VolumeScheduling should be enabled before using this feature. (#67121, @feiskyer)
  • kube-apiserver now includes all registered API groups in discovery, including registered extension API group/versions for unavailable extension API servers. (#66932, @nilebox)
  • Allows extension API server to dynamically discover the requestheader CA certificate when the core API server doesn't use certificate based authentication for it's clients (#66394, @rtripat)
  • audit.k8s.io api group is upgraded from v1beta1 to v1. (#65891, @CaoShuFeng)
    • Deprecated element metav1.ObjectMeta and Timestamp are removed from audit Events in v1 version.
    • Default value of option --audit-webhook-version and --audit-log-version will be changed from audit.k8s.io/v1beta1 to audit.k8s.io/v1 in release 1.13
  • scope AWS LoadBalancer security group ICMP rules to spec.loadBalancerSourceRanges (#63572, @haz-mat)
  • Add NoSchedule/NoExecute tolerations to ip-masq-agent, ensuring it to be scheduled in all nodes except master. (#66260, @tanshanshan)
  • The flag --skip-preflight-checks of kubeadm has been removed. Please use --ignore-preflight-errors instead. (#62727, @xiangpengzhao)
  • The watch API endpoints prefixed with /watch are deprecated and will be removed in a future release. These standard method for watching resources (supported since v1.0) is to use the list API endpoints with a ?watch=true parameter. All client-go clients have used the parameter method since v1.6.0. (#65147, @liggitt)
  • Bump Heapster to v1.6.0-beta.1 (#67074, @kawych)
  • kube-apiserver: setting a dryRun query parameter on a CONNECT request will now cause the request to be rejected, consistent with behavior of other mutating API requests. Examples of CONNECT APIs are the nodes/proxy, services/proxy, pods/proxy, pods/exec, and pods/attach subresources. Note that this prevents sending a dryRun parameter to backends via {nodes,services,pods}/proxy subresources. (#66083, @jennybuckley)
  • In clusters where the DryRun feature is enabled, dry-run requests will go through the normal admission chain. Because of this, ImagePolicyWebhook authors should especially make sure that their webhooks do not rely on side effects. (#66391, @jennybuckley)

Changelog since v1.11.0

Action Required

  • action required: the API server and client-go libraries have been fixed to support additional non-alpha-numeric characters in UserInfo "extra" data keys. Both should be updated in order to properly support extra data containing "/" characters or other characters disallowed in HTTP headers. (#65799, @dekkagaijin)
  • [action required] The NodeConfiguration kind in the kubeadm v1alpha2 API has been renamed JoinConfiguration in v1alpha3 (#65951, @luxas)
  • ACTION REQUIRED: Removes defaulting of CSI file system type to ext4. All the production drivers listed under https://kubernetes-csi.github.io/docs/Drivers.html were inspected and should not be impacted after this change. If you are using a driver not in that list, please test the drivers on an updated test cluster first. ``` (#65499, @krunaljain)
  • [action required] The MasterConfiguration kind in the kubeadm v1alpha2 API has been renamed InitConfiguration in v1alpha3 (#65945, @luxas)
  • [action required] The formerly publicly-available cAdvisor web UI that the kubelet started using --cadvisor-port is now entirely removed in 1.12. The recommended way to run cAdvisor if you still need it, is via a DaemonSet. (#65707, @dims)
  • Cluster Autoscaler version updated to 1.3.1-beta.1. Release notes: https://github.com/kubernetes/autoscaler/releases/tag/cluster-autoscaler-1.3.1-beta.1 (#65857, @aleksandra-malinowska)
    • Default value for expendable pod priority cutoff in GCP deployment of Cluster Autoscaler changed from 0 to -10.
    • action required: users deploying workloads with priority lower than 0 may want to use priority lower than -10 to avoid triggering scale-up.
  • [action required] kubeadm: The v1alpha1 config API has been removed. (#65628, @luxas)
    • Please convert your v1alpha1 configuration files to v1alpha2 using the
    • kubeadm config migrate command of kubeadm v1.11.x
  • kube-apiserver: the Priority admission plugin is now enabled by default when using --enable-admission-plugins. If using --admission-control to fully specify the set of admission plugins, the Priority admission plugin should be added if using the PodPriority feature, which is enabled by default in 1.11. (#65739, @liggitt)
  • The system-node-critical and system-cluster-critical priority classes are now limited to the kube-system namespace by the PodPriority admission plugin. (#65593, @bsalamat)
  • kubernetes-worker juju charm: Added support for setting the --enable-ssl-chain-completion option on the ingress proxy. "action required": if your installation relies on supplying incomplete certificate chains and using OCSP to fill them in, you must set "ingress-ssl-chain-completion" to "true" in your juju configuration. (#63845, @paulgear)

Other notable changes

  • admin RBAC role now aggregates edit and view. edit RBAC role now aggregates view. (#66684, @deads2k)
  • Speed up HPA reaction to metric changes by removing scale up forbidden window. (#66615, @jbartosik)
    • Scale up forbidden window was protecting HPA against making decision to scale up based on metrics gathered during pod initialisation (which may be invalid, for example pod may be using a lot of CPU despite not doing any "actual" work).
    • To avoid that negative effect only use per pod metrics from pods that are:
      • ready (so metrics about them should be valid), or
      • unready but creation and last readiness change timestamps are apart more than 10s (pods that have formerly been ready and so metrics are in at least some cases (pod becoming unready because of overload) very useful).
  • The kubectl patch command no longer exits with exit code 1 when a redundant patch results in a no-op (#66725, @juanvallejo)
  • Improved the output of kubectl get events to prioritize showing the message, and move some fields to -o wide. (#66643, @smarterclayton)

    • dangling references to LUNs that no longer exist, which used to be the
    • cause of random I/O errors/timeouts in kernel logs, slowdowns during
    • block-device related operations, and very rare cases of data corruption.
  • kubeadm: Pull sidecar and dnsmasq-nanny images when using kube-dns (#66499, @rosti)
  • Extender preemption should respect IsInterested() (#66291, @resouer)

  • renamed command line option --cri-socket-path of the kubeadm subcommand "kubeadm config images pull" to --cri-socket to be consistent with the rest of kubeadm subcommands. (#66382, @bart0sh)
  • The --docker-disable-shared-pid kubelet flag has been removed. PID namespace sharing can instead be enable per-pod using the ShareProcessNamespace option. (#66506, @verb)
  • Add support for using User Assigned MSI (https://docs.microsoft.com/en-us/azure/active-directory/managed-service-identity/overview) with Kubernetes cluster on Azure. (#66180, @kkmsft)
  • fix acr could not be listed in sp issue (#66429, @andyzhangx)
