Kubernetes v1.14 Release Notes

1.14 What’s New

Support for Windows Nodes is Graduating to Stable (#116 )

Support for Windows Server 2019 for worker nodes and containers
Support for out of tree networking with Azure-CNI, OVN-Kubernetes and Flannel
Improved support for pods, service types, workload controllers and metrics/quotas to closely match the capabilities offered for Linux containers kubernetes/enhancements: #116 [kep]

Updated Plugin Mechanism for kubectl is Graduating to Stable (#579)

Extends functionality to kubectl to support extensions adding new commands as well as overriding specific subcommands (at any depth).
Documentation fixes kubernetes/enhancements: #579 [kep]

Durable Local Storage Management is Now GA (#121)

Makes locally attached (non-network attached) storage available as a persistent volume source.
Allows users to take advantage of the typically cheaper and improved performance of persistent local storage kubernetes/kubernetes: #73525, #74391, #74769 kubernetes/enhancements: #121 [kep]

Pid Limiting is Graduating to Beta (#757)

Prevents a pod from starving pid resource
Ability to isolate pid resources pod-to-pod and node-to-pod kubernetes/kubernetes: #73651 kubernetes/enhancements: #757 [kep]

Pod Priority and Preemption in Kubernetes (#564)

Pod priority and preemption enables Kubernetes scheduler to schedule more important Pods first and when cluster is out of resources, it removes less important pods to create room for more important ones. The importance is specified by priority. kubernetes/kubernetes: #73498, #73555, #74465 kubernetes/enhancements: #564 [kep]

Pod Ready++ (#580)

Introduces extension point for external feedback on pod readiness. kubernetes/kubernetes: #74434, kubernetes/enhancements: #580 [kep]

Kubeadm: Automate certificate copy between control planes in HA setups

Joining control plane nodes to a HA cluster can now be simplified by enabling the optional automatic copy of certificates from an existing control plane node.
You can now use kubeadm init --experimental-upload-certs and kubeadm join --experimental-control-plane --certificate-key. kubernetes/kubeadm: #1373 kubernetes/enhancements: #357 [kep]

Kubeadm: Expose the kubeadm join workflow as phases

The kubeadm join command can now be used in phases. Similar to the work that was done for kubeadm init in 1.13, in 1.14 the join phases can be now executed step-by-step/selectively using the kubeadm join phase sub-command. This makes it possible to further customize the workflow of joining nodes to the cluster. kubernetes/kubeadm: #1204 kubernetes/enhancements: kep

Known Issues

There is a known issue coredns/coredns#2629 in CoreDNS 1.3.1, wherein if the Kubernetes API shuts down while CoreDNS is connected, CoreDNS will crash. The issue is fixed in CoreDNS 1.4.0 in coredns/coredns#2529.
Kubelet might fail to restart if an existing flexvolume mounted pvc contains a large number of directories, or is full. #75019

Urgent Upgrade Notes

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

kube-apiserver:
- Default RBAC policy no longer grants access to discovery and permission-checking APIs (used by kubectl auth can-i) to unauthenticated users. Upgraded clusters preserve prior behavior, but cluster administrators wishing to grant unauthenticated users access in new clusters will need to explicitly opt-in to expose the discovery and/or permission-checking APIs:
- kubectl create clusterrolebinding anonymous-discovery --clusterrole=system:discovery --group=system:unauthenticated
- kubectl create clusterrolebinding anonymous-access-review --clusterrole=system:basic-user --group=system:unauthenticated
- The deprecated –storage-versions flag has been removed. The storage versions will always be the default value built-in the kube-apiserver binary. (#67678, @caesarxuchao)
- The deprecated --repair-malformed-updates flag has been removed (#73663, @danielqsj)
- The /swaggerapi/* schema docs, deprecated since 1.7, have been removed in favor of the /openapi/v2 schema docs. (#72924, @liggitt)
- The /swagger.json and /swagger-2.0.0.pb-v1 schema documents, deprecated since v1.10, have been removed in favor of /openapi/v2 (#73148, @liggitt)
- kube-apiserver now only aggregates openapi schemas from /openapi/v2 endpoints of aggregated API servers. The fallback to aggregate from /swagger.json has been removed. Ensure aggregated API servers provide schema information via /openapi/v2 (available since v1.10). (#73441, @roycaihw)
- The OpenAPI definitions with the prefix “io.k8s.kubernetes.pkg” (deprecated since 1.9) have been removed. (#74596, @sttts)
- The ValidateProxyRedirects feature was promoted to Beta and enabled by default. This feature restricts redirect-following from the apiserver to same-host redirects. If nodes are configured to respond to CRI streaming requests on a different host interface than what the apiserver makes requests on (only the case if not using the built-in dockershim & setting the kubelet flag --redirect-container-streaming=true), then these requests will be broken. In that case, the feature can be temporarily disabled until the node configuration is corrected. We suggest setting --redirect-container-streaming=false on the kubelet to avoid issues.(#72552, @tallclair)
kubectl
- The deprecated --show-all flag to kubectl get has been removed (#69255, @Pingan2017)
kubelet
- The deprecated --experimental-fail-swap-on flag has been removed (#69552, @Pingan2017)
- Health check (liveness & readiness) probes using an HTTPGetAction will no longer follow redirects to different hostnames from the original probe request. Instead, these non-local redirects will be treated as a Success (the documented behavior). In this case an event with reason “ProbeWarning” will be generated, indicating that the redirect was ignored. If you were previously relying on the redirect to run health checks against different endpoints, you will need to perform the healthcheck logic outside the Kubelet, for instance by proxying the external endpoint rather than redirecting to it. (#75416, @tallclair)
client-go
- The deprecated versionless API group accessors (like clientset.Apps()) have been removed. Use an explicit version instead (like clientset.AppsV1()) (#74422, @liggitt)
- The disk-cached discovery client is moved from k8s.io/client-go/discovery to k8s.io/client-go/discovery/cached/disk. The memory-cached discovery client is moved from k8s.io/client-go/discovery/cached to k8s.io/client-go/discovery/cached/memory. (#72214, @caesarxuchao)
kubeadm
- kubeadm alpha preflight and kubeadm alpha preflight node are removed; you can now use kubeadm join phase preflight (#73718, @fabriziopandini)
The deprecated taints node.alpha.kubernetes.io/notReady and node.alpha.kubernetes.io/unreachable are no longer supported or adjusted. These uses should be replaced with node.kubernetes.io/not-ready and node.kubernetes.io/unreachable (#73001, @shivnagarajan)
Any Prometheus queries that match pod_name and container_name labels (e.g. cadvisor or kubelet probe metrics) should be updated to use pod and container instead. pod_name and container_name labels will be present alongside pod and container labels for one transitional release and removed in the future. (#69099, @ehashman)

Deprecations

- OS and Arch information is now recorded in kubernetes.io/os and kubernetes.io/arch labels on Node objects. The previous labels (beta.kubernetes.io/os and beta.kubernetes.io/arch) are still recorded, but are deprecated and targeted for removal in v1.18. (#73333, @yujuhong)
- The --containerized flag is deprecated and will be removed in a future release (#74267, @dims)
hyperkube
- The --make-symlinks flag is deprecated and will be removed in a future release. (#74975, @dims)
API
- Ingress resources are now available via networking.k8s.io/v1beta1. Ingress resources in extensions/v1beta1 are deprecated and will no longer be served in v1.18. Existing persisted data is available via the new API group/version (#74057, @liggitt)
- NetworkPolicy resources will no longer be served from extensions/v1beta1 in v1.16. Migrate use to the networking.k8s.io/v1 API, available since v1.8. Existing persisted data can be retrieved via the networking.k8s.io/v1 API.
- PodSecurityPolicy resources will no longer be served from extensions/v1beta1 in v1.16. Migrate to the policy/v1beta1 API, available since v1.10. Existing persisted data can be retrieved via the policy/v1beta1 API.
- DaemonSet, Deployment, and ReplicaSet resources will no longer be served from extensions/v1beta1, apps/v1beta1, or apps/v1beta2 in v1.16. Migrate to the apps/v1 API, available since v1.9. Existing persisted data can be retrieved via the apps/v1 API.
- PriorityClass resources have been promoted to scheduling.k8s.io/v1 with no changes. The scheduling.k8s.io/v1beta1 and scheduling.k8s.io/v1alpha1 versions are now deprecated and will stop being served by default in v1.17. (#73555, #74465, @bsalamat)
- The export query parameter for list API calls is deprecated and will be removed in v1.18 (#73783, @deads2k)
The following features are now GA, and the associated feature gates are deprecated and will be removed in v1.15:
- CustomPodDNS
- HugePages
- MountPropagation
- PersistentLocalVolumes
CoreDNS: The following directives or keywords are deprecated and will be removed in v1.15:
- upstream option of kubernetes plugin, becoming default behavior in v1.15.
- proxy plugin replaced by forward plugin

Cluster Lifecycle

kubeadm: fixed nil pointer dereference caused by a bug in url parsing (#74454, @bart0sh)
CoreDNS adds readinessProbe which prevents loadbalancing to unready pods, and also allows rolling updates to work as expected. (#74137, @rajansandeep)
kubeadm no longer allows using v1alpha3 configs for anything else than converting them to v1beta1. (#74025, @rosti)
kubeadm: now allows the usage of --kubeconfig-dir and --config flags on kubeadm init (#73998, @yagonobre)
kubeadm: all master components are now exclusively relying on the PriorityClassName pod spec for annotating them as cluster critical components.

Kubelet no longer watches ConfigMaps and Secrets for terminated pods, in worst scenario causing it to not be able to send other requests to kube-apiserver (#74809, @oxddr)
A new TaintNodesByCondition admission plugin taints newly created Node objects as “not ready”, to fix a race condition that could cause pods to be scheduled on new nodes before their taints were updated to accurately reflect their reported conditions. This admission plugin is enabled by default if the TaintNodesByCondition feature is enabled. (#73097, @bsalamat)
kubelet now accepts pid=<number> in the --system-reserved and --kube-reserved options to ensure that the specified number of process IDs will be reserved for the system as a whole and for Kubernetes system daemons respectively. Please reference Kube Reserved and System Reserved in Reserve Compute Resources for System Daemons in the Kubernetes documentation for general discussion of resource reservation. To utilize this functionality, you must set the feature gate SupportNodePidsLimit=true (#73651

Improved fairness of the scheduling queue by placing pods which are attempted recently behind other pods with the same priority. (#73700, @denkensk)
Improved scheduler robustness to ensure that unschedulable pods are reconsidered for scheduling when appropriate. (#73700, #72558, @denkensk, #73078, @Huang-Wei)

Storage

Fixed scanning of failed iSCSI targets. (#74306, @jsafrane)
StorageOS volume plugin updated to fix an issue where volume mount succeeds even if request to mount via StorageOS API fails. (#69782, @darkowlzz)
Ensured directories on volumes are group-executable when using fsGroup (#73533, @mxey)
Updated CSI version to 1.1 (#75391, @gnufied)
Ensured that volumes get provisioned based on the zone information provided in allowedTopologies. (#72731, @skarthiksrinivas)
Extended the VolumeSubpathEnvExpansion alpha feature to support environment variable expansion (#71351, @kevtaylor)
Fixed a bug that prevented deletion of dynamically provisioned volumes in Quobyte backends. (#68925, @casusbelli)

Testing

e2e storage tests now run faster and are easier to read (#72434, @pohly)
e2e.test now rejects unknown --provider values instead of merely warning about them. An empty provider name is not accepted anymore and was replaced by skeleton (a provider with no special behavior). (#73402, @pohly)
Updated to go1.11.5 (#73326, @ixdy)
Updated to use go1.12.1 (#75413, @BenTheElder)
e2e tests that require SSH may now be used against clusters that have nodes without external IP addresses by setting the environment variable KUBE_SSH_BASTION to the host:port of a machine that is allowed to SSH to those nodes. The same private key that the test would use is used for the bastion host. The test connects to the bastion and then tunnels another SSH connection to the node. (#72286, @smarterclayton)
PidPressure now evicts pods from lowest priority to highest priority (#72844, @dashpole)
Split up the mondo kubernetes-test tarball into kubernetes-test-portable and kubernetes-test-{OS}-{ARCH} tarballs. (#74065, @ixdy)

VMware

Applied zone labels to vSphere Volumes automatically. The zone labels are visible on the PV: (#72687, @subramanian-neelakantan)

Windows

Support for Windows nodes and Windows containers graduated to stable.

Support for Group Managed Service Accounts (GMSA) for Windows containers in Kubernetes is alpha. GMSA are a specific type of Active Directory account that provides automatic password management, simplified service principal name (SPN) management, and the ability to delegate the management to other administrators across multiple servers.

Fixed smb remount and unmount issues on Windows (#73661, @andyzhangx, #75087, @andyzhangx)
Added network stats for Windows nodes and containers (#74788, @feiskyer)
The new test [sig-network] DNS should now provide /etc/hosts entries for the cluster [LinuxOnly] [Conformance] will validate the host entries set in the /etc/hosts file (pod’s FQDN and hostname), which should be managed by Kubelet. (#72729, @bclau)
Allowed the kubelet to pass Windows GMSA credentials down to Docker (#73726, @wk8)
Added kube-proxy support for overlay networking and DSR in Windows and new flags for network-name, source-vip, and enable-dsr. (#70896, @ksubrmnn)
windows: Ensured graceful termination when being run as windows service (#73292, @steffengy)
vSphere cloud provider now correctly retrieves the VM’s UUID when running on Windows (#71147, @benmoss)
Kubelet: added usageNanoCores from CRI stats provider (#73659, @feiskyer)
Introduced support for Windows nodes into the cluster bringup scripts for GCE. (#73442, @pjh)
Added network stats for Windows nodes and pods. (#70121, @feiskyer)
CoreDNS is only officially supported on Linux at this time. As such, when kubeadm is used to deploy this component into your kubernetes cluster, it will be restricted (using nodeSelectors) to run only on nodes with that operating system. This ensures that in clusters which include Windows nodes, the scheduler will not ever attempt to place CoreDNS pods on these machines, reducing setup latency and enhancing initial cluster stability. (#69940, @MarcPow)

ACTION REQUIRED: Health check (liveness & readiness) probes using an HTTPGetAction will no longer follow redirects to different hostnames from the original probe request. Instead, these non-local redirects will be treated as a Success (the documented behavior). In this case an event with reason “ProbeWarning” will be generated, indicating that the redirect was ignored. If you were previously relying on the redirect to run health checks against different endpoints, you will need to perform the healthcheck logic outside the Kubelet, for instance by proxying the external endpoint rather than redirecting to it. (#75416, @tallclair)

Changelog since v1.14.0-beta.1

Action Required

ACTION REQUIRED: The node.k8s.io API group and runtimeclasses.node.k8s.io resource have been migrated to a built-in API. If you were using RuntimeClasses (an default-disabled alpha feature, as of Kubernetes v1.12), then you must recreate all RuntimeClasses after upgrading, and the runtimeclasses.node.k8s.io CRD should be manually deleted. RuntimeClasses can no longer be created without a defined handler. (#74433, @tallclair)
- Introduce a RuntimeClass v1beta1 API. This new beta API renames runtimeHandler to handler, makes it a required field, and cuts out the spec (handler is a top-level field).
Transition CSINodeInfo and CSIDriver alpha CRDs to in-tree CSINode and CSIDriver core storage v1beta1 APIs. (#74283, @xing-yang)
- ACTION REQUIRED: the alpha CRDs are no longer used and drivers will need to be updated to use the beta APIs.
- The support for _ in the CSI driver name will be dropped as the CSI Spec does not allow that.

Other notable changes

Support collecting pod logs under /var/log/pods/NAMESPACE_NAME_UID to stackdriver with k8s_pod resource type. (#74502, @Random-Liu)
–make-symlinks for hyperkube was marked hidden for a while, This flag is now deprecated and will be removed in a future release. (#74975, @dims)
fix smb unmount issue on Windows (#75087, @andyzhangx)
Kubelet no longer watches configmaps and secrets for terminated pods, in worst scenario causing it to not be able to send other requests to kube-apiserver (#74809, @oxddr)
- Fixes a bug concerning Quobyte volumes where user mappings only worked if the hosts Kubernetes plugin mount was provided via an external configuration using the allow-usermapping-in-volumename option. (#74520, @casusbelli)
Change CRI pod log directory from /var/log/pods/UID to /var/log/pods/NAMESPACE_NAME_UID. (#74441, @Random-Liu)
- It is recommended to drain the node before upgrade, or reboot the node after upgrade.
Promote RuntimeClass to beta, and enable by default. (#75003, @tallclair)
New “dry_run” metric label (indicating the value of the dryRun query parameter) into the metrics: (#74997, @jennybuckley) * apiserver_request_total * apiserver_request_duration_seconds
- New “APPLY” value for the “verb” metric label which indicates a PATCH with “Content-Type: apply-patch+yaml”. This value is experimental and will only be present if the ServerSideApply alpha feature is enabled.
GCE: bump COS image version to cos-beta-73-11647-64-0 (#75149, @yguo0905)
- Add duration metric for CRD webhook converters (#74376, @mbohlool)

- - Add mechanism for CRD Conversion Webhooks to specify which version of ConversionReview they support
Add a new kubelet endpoint for serving first-class resource metrics (#73946, @dashpole)
Deprecate AWS, Azure, GCE and Cinder specific volume limit predicates. (#74544, @gnufied)
PodReadinessGate feature is now GA. The feature gate will not allow disabling it. (#74434, @freehan)
If CSINodeInfo and CSIMigration feature flags are active in the cluster, Kubelet will post NotReady until CSINode is initialized with basic volume plugin mechanism information for well-known drivers (#74835, @davidz627)
Add network stats for Windows nodes and containers (#74788, @feiskyer)
kubeadm: when calling “reset” on a control-plane node, remove the APIEndpoint information for this node from the ClusterStatus in the kubeadm ConfigMap. (#75082, @neolit123)
kube-apiserver now serves OpenAPI specs for registered CRDs with defined (#71192, @roycaihw)
- validation schemata as an alpha feature, to be enabled via the “CustomResourcePublishOpenAPI” feature gate. Kubectl will validate client-side using those. Note that in
- future, client-side validation in 1.14 kubectl against a 1.15 cluster will reject
- unknown fields for CRDs with validation schema defined.
Fix kubelet start failure issue on Azure Stack due to InstanceMetadata setting (#74936, @rjaini)
add subcommand kubectl create cronjob (#71651, @Pingan2017)
The CSIBlockVolume feature gate is now beta, and defaults to enabled. (#74909, @bswartz)
Pre-existing log files are now opened with O_APPEND, instead of O_TRUNC. This helps prevent losing logs when components crash-loop, and also enables external log rotation utilities to truncate log files in-place without components extending log files to their pre-truncation sizes on subsequent writes. (#74837, @mtaufen)
the test/e2e/e2e.test binary can test arbitrary storage drivers, see the -storage.testdriver parameter (#72836, @pohly)

In v1.16, the metadata proxy add-on will switch to using that label as a node selector. * setting KUBE_PROXY_DAEMONSET=true in kube-up will now set a node.kubernetes.io/kube-proxy-ds-ready=true label on new nodes. In v1.16, the kube-proxy daemonset add-on will switch to using that label as a node selector. * In 1.16, the masq-agent daemonset add-on will switch to using node.kubernetes.io/masq-agent-ds-ready as a node selector.
- Kubelet: replace du and find with a golang implementation (#74675, @dashpole)
- - Kubelet: periodically update machine info to support hot-add/remove
kubeadm: add certificate-key and skip-certificate-key-print flags to kubeadm init (#74671, @yagonobre)
Admission webhooks rules can now limit scope to only match namespaced, or only cluster-scoped resources with a scope: "Cluster" | "Namespaced" | "*" field. (#74477, @liggitt)
The CSIPersistentVolume and KubeletPluginWatcher feature gates cannot be disabled, and will be removed in Kubernetes v1.16 (#74830, @msau42)
Kubelet won’t evict a static pod with priority system-node-critical upon resource pressure. (#74222, @Huang-Wei)
Fixes panic if a kubelet is run against an older kube-apiserver (#74529, @liggitt)
The resource group name in Azure providerID is not converted to lower cases. (#74882, @feiskyer)
Remove the out-of-tree PersistentVolumeLabel controller because it cannot run without Initializers (removed in v1.14). If you are using AWS EBS, GCE PD, Azure Disk, Cinder Disk or vSphere volumes and rely on zone labels, then enable the PersistentVolumeLabel admission controller in the kube-apiserver in the --enable-admission-plugins flag. (#74615, @andrewsykim)
kubeadm: improved RequiredIPVSKernelModulesAvailable warning message (#74033, @bart0sh)
Add nullable support to CustomResourceDefinition OpenAPI validation schemata. (#74804, @sttts)
Fix kube-apiserver not to create default/kubernetes service endpoints before it reports readiness via the /healthz and therefore is ready to serve requests. Also early during startup old endpoints are remove which might be left over from a previously crashed kube-apiserver. (#74668, @sttts)
kubeadm: fix a bug where standard kubeconfig paths were searched even if the user provided /etc/kubernetes/admin.conf explicitly for commands that accept –kubeconfig, like kubeadm token. (#71874, @neolit123)
- kubeadm: use the default kubeconfig (/etc/kubernetes/admin.conf) for “kubeadm reset” and “kubeadm upgrade” commands.
Increase api server client certificate expiration histogram resolution to accommodate short-lived (< 6h) client certificates. (#74806, @mxinden)
Default RBAC policy no longer grants access to discovery and permission-checking APIs (used by kubectl auth can-i) to unauthenticated users. Upgraded clusters preserve prior behavior, but cluster administrators wishing to grant unauthenticated users access in new clusters will need to explicitly opt-in to expose the discovery and/or permission-checking APIs: (#73807, @dekkagaijin) * kubectl create clusterrolebinding anonymous-discovery --clusterrole=system:discovery --group=system:unauthenticated * kubectl create clusterrolebinding anonymous-access-review --clusterrole=system:basic-user --group=system:unauthenticated
The PersistentLocalVolumes feature is GA. The feature gate cannot be disabled and will be removed in Kubernetes 1.17 (#74769, @msau42)
kubelet: resolved hang/timeout issues when running large numbers of pods with unique configmap/secret references by reverting to 1.11 configmap/secret lookup behavior (#74755, @liggitt)
Convert latency/latencies in metrics name to duration. (#74418, @danielqsj)
- The following metrics are changed and mark previous metrics as deprecated:
  - rest_client_request_latency_seconds -> rest_client_request_duration_seconds
  - apiserver_proxy_tunnel_sync_latency_secs -> apiserver_proxy_tunnel_sync_duration_seconds
  - scheduler_scheduling_latency_seconds -> scheduler_scheduling_duration_seconds
Fix help message for –container-runtime-endpoint: only unix socket is support on Linux. (#74712, @feiskyer)
Update to use golang 1.12 (#74632, @cblecker)
The RunAsGroup feature has been promoted to beta and enabled by default. PodSpec and PodSecurityPolicy objects can be used to control the primary GID of containers on supported container runtimes. (#73007, @krmayankk)
fix Azure Container Registry anonymous repo image pull error (#74715, @andyzhangx)
Adds the same information to an init container as a standard container in a pod when using PodPresets. (#71479, @soggiest)
fix the flake in scheduling_queue_test.go (#74611, @denkensk)
The kube-apiserver OpenAPI definitions with the prefix “io.k8s.kubernetes.pkg” (deprecated since 1.9) have been removed. (#74596, @sttts)
kube-conformance image will now run ginkgo with the –dryRun flag if the container is run with the environment variable E2E_DRYRUN set. (#74731, @johnSchnake)
The deprecated MountPropagation feature gate has been removed, and the feature is now unconditionally enabled. (#74720, @bertinatto)
Introduce dynamic volume provisioning shim for CSI migration (#73653, @ddebroy)
Fix –help flag parsing (#74682, @soltysh)
This PR removes the following metrics: (#74636, @logicalhan)

- reflector_items_per_watch
- reflector_last_resource_version
- reflector_list_duration_seconds
- reflector_lists_total
- reflector_short_watches_total
- reflector_watch_duration_seconds
- reflector_watches_total
- While this is a backwards-incompatible change, it would have been impossible to setup reliable monitoring around these metrics since the labels were not stable.
Add a configuration field to shorten the timeout of validating/mutating admission webhook call. The timeout value must be between 1 and 30 seconds. Default to 30 seconds when unspecified. (#74562, @roycaihw)
client-go: PortForwarder.GetPorts() now contain correct local port if no local port was initially specified when setting up the port forwarder (#73676, @martin-helmich)
# Apply resources from a directory containing kustomization.yaml (#74140, @Liujingfang1)
- kubectl apply -k dir
- # Delete resources from a directory containing kustomization.yaml.
- kubectl delete -k dir
- # List resources from a directory containing kustomization.yaml
- kubectl get -k dir
kubeadm: Allow to download certificate secrets uploaded by init or upload-certs phase, allowing to transfer certificate secrets (certificates and keys) from the cluster to other master machines when creating HA deployments. (#74168, @ereslibre)
Fixes an issue with missing apiVersion/kind in object data sent to admission webhooks (#74448, @liggitt)
client-go: the deprecated versionless API group accessors (like clientset.Apps() have been removed). Use an explicit version instead (like clientset.AppsV1()) (#74422, @liggitt)
The --quiet option to kubectl run now suppresses resource deletion messages emitted when the --rm option is specified. (#73266, @awh)
Add Custom Resource support to “kubectl autoscale” (#72678, @rmohr)

The new test [sig-network] DNS should provide /etc/hosts entries for the cluster [LinuxOnly] [Conformance] will validate the host entries set in the /etc/hosts file (pod’s FQDN and hostname), which should be managed by Kubelet. (#72729, @bclau)
- The test has the tag [LinuxOnly] because individual files cannot be mounted in Windows Containers, which means that it cannot pass using Windows nodes.

Changelog since v1.14.0-alpha.3

Action Required

Added cadvisor metric labels pod and container where pod_name and container_name are present to match instrumentation guidelines. (#69099, @ehashman)
- Action required: any Prometheus queries that match pod_name and container_name labels (e.g. cadvisor or kubelet probe metrics) should be updated to use pod and container instead. pod_name and container_name labels will be present alongside pod and container labels for one transitional release and removed in the future.

vSphere cloud provider correctly retrieves the VM’s UUID when running on Windows (#71147, @benmoss)
Re-issue Allocate grpc calls before starting a container that requests device-plugin resources if the cached state is missing. (#73824, @jiayingz)
[CRI] Add a new field called runtime_handler into PodSandbox and PodSandboxStatus to track the RuntimeClass information of a pod. (#73833, @haiyanmeng)
kubelet: OS and Arch information is now recorded in kubernetes.io/os and kubernetes.io/arch labels on Node objects. The previous labels (beta.kubernetes.io/os and beta.kubernetes.io/arch) are still recorded, but are deprecated and targeted for removal in 1.18. (#73333, @yujuhong)
This change applies zone labels to vSphere Volumes automatically. The zone labels are visible on the PV: (#72687, @subramanian-neelakantan)
- $ kubectl get pv –show-labels

Kubelet now tries to stop containers in unknown state once before restart or remove. (#73802, @Random-Liu)
Deprecate –export flag from kubectl get command. (#73787, @soltysh)
Breaking changes in client-go: (#72214, @caesarxuchao)
- The disk-cached discovery client is moved from k8s.io/client-go/discovery to k8s.io/client-go/discovery/cached/disk.
- The memory-cached discovery client is moved from k8s.io/client-go/discovery/cached to k8s.io/client-go/discovery/cached/memory.
kubelet now accepts pid=<number> in the --system-reserved and --kube-reserved options to ensure that the specified number of process IDs will be reserved for the system as a whole and for Kubernetes system daemons respectively. Please reference Kube Reserved and System Reserved in Reserve Compute Resources for System Daemons in the Kubernetes documentation for general discussion of resource reservation. To utilize this functionality, you must set the feature gate SupportNodePidsLimit=true (#73651, @RobertKrawitz)
The apiserver, including both the kube-apiserver and apiservers built with the generic apiserver library, will now return 413 RequestEntityTooLarge error if a json patch contains more than 10,000 operations. (#74000, @caesarxuchao)
kubeadm: allow the usage of –kubeconfig-dir and –config flags on kubeadm init (#73998, @yagonobre)

Is ->It in line 6 (#73898, @xiezongzhe)
Events reported for container creation, start, and stop now report the container name in the message and are more consistently formatted. (#73892, @smarterclayton)
kubectl auth reconcile now outputs details about what changes are being made (#71564, @liggitt)
kubeadm: fix a bug in the underlying library for diff related to characters like ‘%’ (#73941, @neolit123)
kube-apiserver: a request body of a CREATE/UPDATE/PATCH/DELETE resource operation larger than 100 MB will return a 413 “request entity too large” error. (#73805, @caesarxuchao)
- Custom apiservers built with the latest apiserver library will have the 100MB limit on the body of resource requests as well. The limit can be altered via ServerRunOptions.MaxRequestBodyBytes.
- The body size limit does not apply to subresources like pods/proxy that proxy request content to another server.
Kustomize is developed in its own repo https://github.com/kubernetes-sigs/kustomize (#73033, @Liujingfang1)
- This PR added a new subcommand kustomize in kubectl.
- kubectl kustomize has the same effect as kustomize build
- To build API resources from somedir with a kustomization.yaml file
- kubectl kustomize
- This command can be piped to apply or delete
- kubectl kustomize | kubectl apply -f -
- kubectl kustomize | kubectl delete -f -
kubeadm: all master components are now exclusively relying on the PriorityClassName pod spec for annotating them as cluster critical components. Since scheduler.alpha.kubernetes.io/critical-pod annotation is no longer supported by Kubernetes 1.14 this annotation is no longer added to master components. (#73857, @ereslibre)
Speedup kubectl by >10 when calling out to kube-apiserver for discovery information. (#73345, @sttts)
kubeadm no longer dumps backtrace if it fails to remove the running containers on reset. (#73951, @rosti)

Changelog since v1.14.0-alpha.1

Action Required

Promote ValidateProxyRedirects to Beta, and enable by default. This feature restricts redirect following from the apiserver to same-host redirects. (#72552, @tallclair)
- ACTION REQUIRED: If nodes are configured to respond to CRI streaming requests on a different host interface than what the apiserver makes requests on (only the case if not using the built-in dockershim & setting the kubelet flag --redirect-container-streaming=true), then these requests will be broken. In that case, the feature can be temporarily disabled until the node configuration is corrected. We suggest setting --redirect-container-streaming=false on the kubelet to avoid issues.

Other notable changes

Added alpha field storageVersionHash to the discovery document for each resource. Its value must be treated as opaque by clients. Only equality comparison on the value is valid. (#73191, @caesarxuchao)
Fix admission metrics in seconds. (#72343, @danielqsj)
- Add metrics *_admission_latencies_milliseconds and *_admission_latencies_milliseconds_summary for backward compatible, but will be removed in a future release.
Pod eviction now honors graceful deletion by default if no delete options are provided in the eviction request (#72730, @liggitt)
Update to go1.11.5 (#73326, @ixdy)
Change proxy metrics to conform metrics guidelines. (#72334, @danielqsj)
- The metrics sync_proxy_rules_latency_microseconds is deprecated, and will be removed in a future release, please convert to metricssync_proxy_rules_latency_seconds.
Add network stats for Windows nodes and pods. (#70121, @feiskyer)
kubeadm: When certificates are present joining a new control plane make sure that they match at least the required SANs (#73093, @ereslibre)
A new TaintNodesByCondition admission plugin taints newly created Node objects as “not ready”, to fix a race condition that could cause pods to be scheduled on new nodes before their taints were updated to accurately reflect their reported conditions. This admission plugin is enabled by default if the TaintNodesByCondition feature is enabled. (#73097, @bsalamat)
kube-addon-manager was updated to v9.0, and now uses kubectl v1.13.2 and prunes workload resources via the apps/v1 API (#72978, @liggitt)
When a watch is closed by an HTTP2 load balancer and we are told to go away, skip printing the message to stderr by default. (#73277, @smarterclayton)
If you are running the cloud-controller-manager and you have the pvlabel.kubernetes.io alpha Initializer enabled, you must now enable PersistentVolume labeling using the PersistentVolumeLabel admission controller instead. You can do this by adding PersistentVolumeLabel in the --enable-admission-plugins kube-apiserver flag. (#73102, @andrewsykim)
The alpha Initializers feature, admissionregistration.k8s.io/v1alpha1 API version, Initializers admission plugin, and use of the metadata.initializers API field have been removed. Discontinue use of the alpha feature and delete any existing InitializerConfiguration API objects before upgrading. The metadata.initializers field will be removed in a future release. (#72972, @liggitt)
Scale max-inflight limits together with master VM sizes. (#73268, @wojtek-t)
kubectl supports copying files with wild card (#72641, @dixudx)
kubeadm: add back --cert-dir option for kubeadm init phase certs sa (#73239, @mattkelly)
Remove deprecated args ‘–show-all’ (#69255, @Pingan2017)
As per deprecation policy in https://kubernetes.io/docs/reference/using-api/deprecation-policy/ (#73001, @shivnagarajan)
- the taints “node.alpha.kubernetes.io/notReady” and “node.alpha.kubernetes.io/unreachable”. are no
- longer supported or adjusted. These uses should be replaced with “node.kubernetes.io/not-ready”
- and “node.kubernetes.io/unreachable” respectively instead.
The /swagger.json and /swagger-2.0.0.pb-v1 schema documents, deprecated since v1.10, have been removed in favor of /openapi/v2 (#73148, @liggitt)
CoreDNS is only officially supported on Linux at this time. As such, when kubeadm is used to deploy this component into your kubernetes cluster, it will be restricted (using nodeSelectors) to run only on nodes with that operating system. This ensures that in clusters which include Windows nodes, the scheduler will not ever attempt to place CoreDNS pods on these machines, reducing setup latency and enhancing initial cluster stability. (#69940, @MarcPow)
kubeadm now attempts to detect an installed CRI by its usual domain socket, so that –cri-socket can be omitted from the command line if Docker is not used and there is a single CRI installed. (#69366, @rosti)
scheduler: makes pod less racing so as to be put back into activeQ properly (#73078, @Huang-Wei)
jsonpath expressions containing [start:end:step] slice are now evaluated correctly (#73149, @liggitt)
metadata.deletionTimestamp is no longer moved into the future when issuing repeated DELETE requests against a resource containing a finalizer. (#73138, @liggitt)
The “kubectl api-resources” command will no longer fail to display any resources on a single failure (#73035, @juanvallejo)
e2e tests that require SSH may be used against clusters that have nodes without external IP addresses by setting the environment variable KUBE_SSH_BASTION to the host:port of a machine that is allowed to SSH to those nodes. The same private key that the test would use is used for the bastion host. The test connects to the bastion and then tunnels another SSH connection to the node. (#72286, @smarterclayton)
kubeadm: explicitly wait for etcd to have grown when joining a new control plane (#72984, @ereslibre)
Install CSINodeInfo and CSIDriver CRDs in the local cluster. (#72584, @xing-yang)
kubectl loads config file once and uses persistent client config (#71117, @dixudx)
remove stale OutOfDisk condition from kubelet side (#72507, @dixudx)
Node OS/arch labels are promoted to GA (#73048, @yujuhong)
Fix graceful apiserver shutdown to not drop outgoing bytes before the process terminates. (#72970, @sttts)
Change apiserver metrics to conform metrics guidelines. (#72336, @danielqsj)

Changelog since v1.13.0

Action Required

action required (#68753, @johnSchnake)
- If you are running E2E tests which require SSH keys and you utilize environment variables to override their location, you may need to modify the environment variable set. On all providers the environment variable override can now be either an absolute path to the key or a relative path (relative to ~/.ssh). Specifically the changes are:
- - Created new GCE_SSH_KEY allowing specification of SSH keys for gce, gke, and kubemark.
- - AWS_SSH_KEY, previously assumed to be an absolute path can now be either relative or absolute
- - LOCAL_SSH_KEY (for local and vsphere providers) was previously assumed to be a filename relative to ~/.ssh but can now also be an absolute path
- - KUBE_SSH_KEY (for skeleton provider) was previously assumed to be a filename relative to ~/.ssh but can now also be an absolute path

Other notable changes

Connections from Pods to Services with 0 endpoints will now ICMP reject immediately, rather than blackhole and timeout. (#72534, @thockin)

client-go: fake clients now properly return NotFound errors when attempting to patch non-existent objects (#70886, @bouk)
kubectl: fixes a bug determining the correct namespace while running in a pod when the --context flag is explicitly specified, and the referenced context specifies the namespace default (#72529, @liggitt)
Fix scheduling starvation of pods in cluster with large number of unschedulable pods. (#72619, @everpeace)
If the AppArmor feature gate is disabled, AppArmor-specific annotations in pod and pod templates are dropped when the object is created, and during update of objects that do not already contain AppArmor annotations, rather than triggering a validation error. (#72655, @liggitt)
client-go: shortens refresh period for token files to 1 minute to ensure auto-rotated projected service account tokens are read frequently enough. (#72437, @liggitt)

kube-apiserver: --runtime-config can once again be used to enable/disable serving specific resources in the extensions/v1beta1 API group. Note that specific resource enablement/disablement is only allowed for the extensions/v1beta1 API group for legacy reasons. Attempts to enable/disable individual resources in other API groups will print a warning, and will return an error in future releases. (#72249, @liggitt)
