• Fixed bug in reflector that couldn't recover from "Too large resource version" errors with API servers 1.17.0-1.18.5 (#94316, @janeczku) [SIG API Machinery]

• Fixed the EndpointSliceController to correctly create endpoints for IPv6-only pods.

  Fixed the EndpointController to allow IPv6 headless services, if the IPv6DualStack feature gate is enabled, by specifying ipFamily: IPv6 on the service. (This already worked with the EndpointSliceController.) (#91399, @danwinship) [SIG Apps and Network]

• Fixes a bug evicting pods after a taint with a limited tolerationSeconds toleration is removed from a node (#93722, @liggitt) [SIG Apps and Node]

Changelog since v1.18.5

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

API Change

• Fix bug in reflector that couldn't recover from "Too large resource version" errors (#92537, @wojtek-t) [SIG API Machinery]

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]

• Containers which specify a startupProbe but not a readinessProbe were previously considered "ready" before the startupProbe completed, but are now considered "not-ready". (#92196, @thockin) [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 throttling issues when Azure VM computer name prefix is different from VMSS name (#92793, @feiskyer) [SIG Cloud Provider]

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

• Fix: don't use docker config cache if it's empty (#92330, @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]

• Kubeadm: during "join", don't re-add an etcd member if it already exists in the cluster. (#92118, @neolit123) [SIG Cluster Lifecycle]

• hyperkube: Use [email protected] image

  Includes iproute2 to fix a regression in hyperkube images when using hyperkube as a kubelet (#92624, @justaugustus) [SIG Cluster Lifecycle, Network and Release]

Changelog since v1.18.4

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

• Fixes CSI volume attachment scaling issue by using informers. (#91307, @yuga711) [SIG API Machinery, Apps, Node, Storage and Testing]

• Kubeadm increased to 5 minutes its timeout for the TLS bootstrapping process to complete upon join (#89735, @rosti) [SIG Cluster Lifecycle]

• hyperkube: Use [email protected] image

  A previous release built hyperkube using the [email protected], 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:

  • kubernetes#92275
  • kubernetes#92272
  • kubernetes#92250

  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. (#92493, @justaugustus) [SIG Cluster Lifecycle and Release]

What’s New (Major Themes)

Kubernetes Topology Manager Moves to Beta - Align Up!

A beta feature of Kubernetes in release 1.18, the Topology Manager feature enables NUMA alignment of CPU and devices (such as SR-IOV VFs) that will allow your workload to run in an environment optimized for low-latency. Prior to the introduction of the Topology Manager, the CPU and Device Manager would make resource allocation decisions independent of each other. This could result in undesirable allocations on multi-socket systems, causing degraded performance on latency critical applications.

Serverside Apply - Beta 2

Server-side Apply was promoted to Beta in 1.16, but is now introducing a second Beta in 1.18. This new version will track and manage changes to fields of all new Kubernetes objects, allowing you to know what changed your resources and when.

Extending Ingress with and replacing a deprecated annotation with IngressClass

In Kubernetes 1.18, there are two significant additions to Ingress: A new pathType field and a new IngressClass resource. The pathType field allows specifying how paths should be matched. In addition to the default ImplementationSpecific type, there are new Exact and Prefix path types.

The IngressClass resource is used to describe a type of Ingress within a Kubernetes cluster. Ingresses can specify the class they are associated with by using a new ingressClassName field on Ingresses. This new resource and field replace the deprecated kubernetes.io/ingress.class annotation.

SIG CLI introduces kubectl debug

SIG CLI was debating the need for a debug utility for quite some time already. With the development of ephemeral containers, it became more obvious how we can support developers with tooling built on top of kubectl exec. The addition of the kubectl debug command (it is alpha but your feedback is more than welcome), allows developers to easily debug their Pods inside the cluster. We think this addition is invaluable. This command allows one to create a temporary container which runs next to the Pod one is trying to examine, but also attaches to the console for interactive troubleshooting.

Introducing Windows CSI support alpha for Kubernetes

With the release of Kubernetes 1.18, an alpha version of CSI Proxy for Windows is getting released. CSI proxy enables non-privileged (pre-approved) containers to perform privileged storage operations on Windows. CSI drivers can now be supported in Windows by leveraging CSI proxy. SIG Storage made a lot of progress in the 1.18 release. In particular, the following storage features are moving to GA in Kubernetes 1.18:

• Raw Block Support: Allow volumes to be surfaced as block devices inside containers instead of just mounted filesystems.
• Volume Cloning: Duplicate a PersistentVolumeClaim and underlying storage volume using the Kubernetes API via CSI.
• CSIDriver Kubernetes API Object: Simplifies CSI driver discovery and allows CSI Drivers to customize Kubernetes behavior.

SIG Storage is also introducing the following new storage features as alpha in Kubernetes 1.18:

• Windows CSI Support: Enabling containerized CSI node plugins in Windows via new CSIProxy
• Recursive Volume Ownership OnRootMismatch Option: Add a new “OnRootMismatch” policy that can help shorten the mount time for volumes that require ownership change and have many directories and files.

Other notable announcements

SIG Network is moving IPv6 to Beta in Kubernetes 1.18, after incrementing significantly the test coverage with new CI jobs.

NodeLocal DNSCache is an add-on that runs a dnsCache pod as a daemonset to improve clusterDNS performance and reliability. The feature has been in Alpha since 1.13 release. The SIG Network is announcing the GA graduation of Node Local DNSCache #1351

Known Issues

No Known Issues Reported

Urgent Upgrade Notes

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

kube-apiserver:

• in an --encryption-provider-config config file, an explicit cacheSize: 0 parameter previously silently defaulted to caching 1000 keys. In Kubernetes 1.18, this now returns a config validation error. To disable caching, you can specify a negative cacheSize value in Kubernetes 1.18+.
• consumers of the 'certificatesigningrequests/approval' API must now have permission to 'approve' CSRs for the specific signer requested by the CSR. More information on the new signerName field and the required authorization can be found at https://kubernetes.io/docs/reference/access-authn-authz/certificate-signing-requests#authorization (#88246, @munnerz) [SIG API Machinery, Apps, Auth, CLI, Node and Testing]
• The following features are unconditionally enabled and the corresponding --feature-gates flags have been removed: PodPriority, TaintNodesByCondition, ResourceQuotaScopeSelectors and ScheduleDaemonSetPods (#86210, @draveness) [SIG Apps and Scheduling]

kubelet:

• --enable-cadvisor-json-endpoints is now disabled by default. If you need access to the cAdvisor v1 Json API please enable it explicitly in the kubelet command line. Please note that this flag was deprecated in 1.15 and will be removed in 1.19. (#87440, @dims) [SIG Instrumentation, Node and Testing]
• Promote CSIMigrationOpenStack to Beta (off by default since it requires installation of the OpenStack Cinder CSI Driver. The in-tree AWS OpenStack Cinder driver "kubernetes.io/cinder" was deprecated in 1.16 and will be removed in 1.20. Users should enable CSIMigration + CSIMigrationOpenStack features and install the OpenStack Cinder CSI Driver (https://github.com/kubernetes/cloud-provider-openstack) to avoid disruption to existing Pod and PVC objects at that time. Users should start using the OpenStack Cinder CSI Driver directly for any new volumes. (#85637, @dims) [SIG Cloud Provider]

kubectl:

• kubectl and k8s.io/client-go no longer default to a server address of http://localhost:8080. If you own one of these legacy clusters, you are strongly encouraged to secure your server. If you cannot secure your server, you can set the $KUBERNETES_MASTER environment variable to http://localhost:8080 to continue defaulting the server address. kubectl users can also set the server address using the --server flag, or in a kubeconfig file specified via --kubeconfig or $KUBECONFIG. (#86173, @soltysh) [SIG API Machinery, CLI and Testing]
• kubectl run has removed the previously deprecated generators, along with flags unrelated to creating pods. kubectl run now only creates pods. See specific kubectl create subcommands to create objects other than pods. (#87077, @soltysh) [SIG Architecture, CLI and Testing]
• The deprecated command kubectl rolling-update has been removed (#88057, @julianvmodesto) [SIG Architecture, CLI and Testing]

client-go:

• Signatures on methods in generated clientsets, dynamic, metadata, and scale clients have been modified to accept context.Context as a first argument. Signatures of Create, Update, and Patch methods have been updated to accept CreateOptions, UpdateOptions and PatchOptions respectively. Signatures of Delete and DeleteCollection methods now accept DeleteOptions by value instead of by reference. Generated clientsets with the previous interface have been added in new "deprecated" packages to allow incremental migration to the new APIs. The deprecated packages will be removed in the 1.21 release. A tool is available at http://sigs.k8s.io/clientgofix to rewrite method invocations to the new signatures.

Changelog since v1.18.0-beta.1

Urgent Upgrade Notes

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

• kubectl no longer defaults to http://localhost:8080. If you own one of these legacy clusters, you are *strongly- encouraged to secure your server. If you cannot secure your server, you can set KUBERNETES_MASTER if you were relying on that behavior and you're a client-go user. Set --server, --kubeconfig or KUBECONFIG to make it work in kubectl. (#86173, @soltysh) [SIG API Machinery, CLI and Testing]

Changes by Kind

Deprecation

• AlgorithmSource is removed from v1alpha2 Scheduler ComponentConfig (#87999, @damemi) [SIG Scheduling]
• Kube-proxy: deprecate --healthz-port and --metrics-port flag, please use --healthz-bind-address and --metrics-bind-address instead (#88512, @SataQiu) [SIG Network]
• Kubeadm: deprecate the usage of the experimental flag '--use-api' under the 'kubeadm alpha certs renew' command. (#88827, @neolit123) [SIG Cluster Lifecycle]

API Change

• A new IngressClass resource has been added to enable better Ingress configuration. (#88509, @robscott) [SIG API Machinery, Apps, CLI, Network, Node and Testing]
• Added GenericPVCDataSource feature gate to enable using arbitrary custom resources as the data source for a PVC. (#88636, @bswartz) [SIG Apps and Storage]
• Allow user to specify fsgroup permission change policy for pods (#88488, @gnufied) [SIG Apps and Storage]
• BlockVolume and CSIBlockVolume features are now GA. (#88673, @jsafrane) [SIG Apps, Node and Storage]
• CustomResourceDefinition schemas that use x-kubernetes-list-map-keys to specify properties that uniquely identify list items must make those properties required or have a default value, to ensure those properties are present for all list items. See https://kubernetes.io/docs/reference/using-api/api-concepts/&#35;merge-strategy for details. (#88076, @eloyekunle) [SIG API Machinery and Testing]
• Fixes a regression with clients prior to 1.15 not being able to update podIP in pod status, or podCIDR in node spec, against >= 1.16 API servers (#88505, @liggitt) [SIG Apps and Network]
• Ingress: Add Exact and Prefix maching to Ingress PathTypes (#88587, @cmluciano) [SIG Apps, Cluster Lifecycle and Network]
• Ingress: Add alternate backends via TypedLocalObjectReference (#88775, @cmluciano) [SIG Apps and Network]
• Ingress: allow wildcard hosts in IngressRule (#88858, @cmluciano) [SIG Network]
• Kube-controller-manager and kube-scheduler expose profiling by default to match the kube-apiserver. Use --enable-profiling=false to disable. (#88663, @deads2k) [SIG API Machinery, Cloud Provider and Scheduling]
• Move TaintBasedEvictions feature gates to GA (#87487, @skilxn-go) [SIG API Machinery, Apps, Node, Scheduling and Testing]
• New flag --endpointslice-updates-batch-period in kube-controller-manager can be used to reduce number of endpointslice updates generated by pod changes. (#88745, @mborsz) [SIG API Machinery, Apps and Network]
• Scheduler Extenders can now be configured in the v1alpha2 component config (#88768, @damemi) [SIG Release, Scheduling and Testing]
• The apiserver/v1alph1#EgressSelectorConfiguration API is now beta. (#88502, @caesarxuchao) [SIG API Machinery]
• The storage.k8s.io/CSIDriver has moved to GA, and is now available for use. (#84814, @huffmanca) [SIG API Machinery, Apps, Auth, Node, Scheduling, Storage and Testing]
• VolumePVCDataSource moves to GA in 1.18 release (#88686, @j-griffith) [SIG Apps, CLI and Cluster Lifecycle]

Feature

• Add rest_client_rate_limiter_duration_seconds metric to component-base to track client side rate limiter latency in seconds. Broken down by verb and URL. (#88134, @jennybuckley) [SIG API Machinery, Cluster Lifecycle and Instrumentation]
• Allow user to specify resource using --filename flag when invoking kubectl exec (#88460, @soltysh) [SIG CLI and Testing]
• Apiserver add a new flag --goaway-chance which is the fraction of requests that will be closed gracefully(GOAWAY) to prevent HTTP/2 clients from getting stuck on a single apiserver. After the connection closed(received GOAWAY), the client's other in-flight requests won't be affected, and the client will reconnect. The flag min value is 0 (off), max is .02 (1/50 requests); .001 (1/1000) is a recommended starting point. Clusters with single apiservers, or which don't use a load balancer, should NOT enable this. (#88567, @answer1991) [SIG API Machinery]
• Azure: add support for single stack IPv6 (#88448, @aramase) [SIG Cloud Provider]
• DefaultConstraints can be specified for the PodTopologySpread plugin in the component config (#88671, @alculquicondor) [SIG Scheduling]

• Kubectl cluster-info dump changed to only display a message telling you the location where the output was written when the output is not standard output. (#88765, @brianpursley) [SIG CLI]
• Print NotReady when pod is not ready based on its conditions. (#88240, @soltysh) [SIG CLI]
• Scheduler Extender API is now located under k8s.io/kube-scheduler/extender (#88540, @damemi) [SIG Release, Scheduling and Testing]
• Signatures on scale client methods have been modified to accept context.Context as a first argument. Signatures of Get, Update, and Patch methods have been updated to accept GetOptions, UpdateOptions and PatchOptions respectively. (#88599, @julianvmodesto) [SIG API Machinery, Apps, Autoscaling and CLI]
• Signatures on the dynamic client methods have been modified to accept context.Context as a first argument.

Changelog since v1.18.0-beta.0

Urgent Upgrade Notes

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

• The StreamingProxyRedirects feature and --redirect-container-streaming flag are deprecated, and will be removed in a future release. The default behavior (proxy streaming requests through the kubelet) will be the only supported option. If you are setting --redirect-container-streaming=true, then you must migrate off this configuration. The flag will no longer be able to be enabled starting in v1.20. If you are not setting the flag, no action is necessary. (#88290, @tallclair) [SIG API Machinery and Node]

• Yes.

  Feature Name: Support using network resources (VNet, LB, IP, etc.) in different AAD Tenant and Subscription than those for the cluster.

  Changes in Pull Request:

  1. Add properties networkResourceTenantID and networkResourceSubscriptionID in cloud provider auth config section, which indicates the location of network resources.
  2. Add function GetMultiTenantServicePrincipalToken to fetch multi-tenant service principal token, which will be used by Azure VM/VMSS Clients in this feature.
  3. Add function GetNetworkResourceServicePrincipalToken to fetch network resource service principal token, which will be used by Azure Network Resource (Load Balancer, Public IP, Route Table, Network Security Group and their sub level resources) Clients in this feature.
  4. Related unit tests.

  None.

• Add huge page stats to Allocated resources in "kubectl describe node" (#80605, @odinuge) [SIG CLI]
• Kubeadm: The ClusterStatus struct present in the kubeadm-config ConfigMap is deprecated and will be removed on a future version. It is going to be maintained by kubeadm until it gets removed. The same information can be found on etcd and kube-apiserver pod annotations, kubeadm.kubernetes.io/etcd.advertise-client-urls and kubeadm.kubernetes.io/kube-apiserver.advertise-address.endpoint respectively. (#87656, @ereslibre) [SIG Cluster Lifecycle]
• Kubeadm: add the experimental feature gate PublicKeysECDSA that can be used to create a cluster with ECDSA certificates from "kubeadm init".

Changelog since v1.18.0-alpha.3

Deprecation

• Kubeadm: command line option "kubelet-version" for kubeadm upgrade node has been deprecated and will be removed in a future release. (#87942, @SataQiu) [SIG Cluster Lifecycle]

API Change

• Kubelet podresources API now provides the information about active pods only. (#79409, @takmatsu) [SIG Node]
• Remove deprecated fields from .leaderElection in kubescheduler.config.k8s.io/v1alpha2 (#87904, @alculquicondor) [SIG Scheduling]
• Signatures on generated clientset methods have been modified to accept context.Context as a first argument. Signatures of generated Create, Update, and Patch methods have been updated to accept CreateOptions, UpdateOptions and PatchOptions respectively. Clientsets that with the previous interface have been added in new "deprecated" packages to allow incremental migration to the new APIs. The deprecated packages will be removed in the 1.21 release. (#87299, @mikedanese) [SIG API Machinery, Apps, Auth, Autoscaling, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Scheduling, Storage, Testing and Windows]
• The k8s.io/node-api component is no longer updated. Instead, use the RuntimeClass types located within k8s.io/api, and the generated clients located within k8s.io/client-go (#87503, @liggitt) [SIG Node and Release]

Feature

• Add indexer for storage cacher (#85445, @shaloulcy) [SIG API Machinery]
• Add support for mount options to the FC volume plugin (#87499, @ejweber) [SIG Storage]
• Added a config-mode flag in azure auth module to enable getting AAD token without spn: prefix in audience claim. When it's not specified, the default behavior doesn't change. (#87630, @weinong) [SIG API Machinery, Auth, CLI and Cloud Provider]
• Introduced BackoffManager interface for backoff management (#87829, @zhan849) [SIG API Machinery]
• PodTopologySpread plugin now excludes terminatingPods when making scheduling decisions. (#87845, @Huang-Wei) [SIG Scheduling]
• Promote CSIMigrationOpenStack to Beta (off by default since it requires installation of the OpenStack Cinder CSI Driver) The in-tree AWS OpenStack Cinder "kubernetes.io/cinder" was already deprecated a while ago and will be removed in 1.20. Users should enable CSIMigration + CSIMigrationOpenStack features and install the OpenStack Cinder CSI Driver (https://github.com/kubernetes/cloud-provider-openstack) to avoid disruption to existing Pod and PVC objects at that time. Users should start using the OpenStack Cinder CSI Driver directly for any new volumes. (#85637, @dims) [SIG Cloud Provider]

Design

• The scheduler Permit extension point doesn't return a boolean value in its Allow() and Reject() functions. (#87936, @Huang-Wei) [SIG Scheduling]

Other (Bug, Cleanup or Flake)

• Adds "volume.beta.kubernetes.io/migrated-to" annotation to PV's and PVC's when they are migrated to signal external provisioners to pick up those objects for Provisioning and Deleting. (#87098, @davidz627) [SIG Apps and Storage]
• Fix a bug in the dual-stack IPVS proxier where stale IPv6 endpoints were not being cleaned up (#87695, @andrewsykim) [SIG Network]
• Fix kubectl drain ignore daemonsets and others. (#87361, @zhouya0) [SIG CLI]
• Fix: add azure disk migration support for CSINode (#88014, @andyzhangx) [SIG Cloud Provider and Storage]
• Fix: add non-retriable errors in azure clients (#87941, @andyzhangx) [SIG Cloud Provider]
• Fixed NetworkPolicy validation that Except values are accepted when they are outside the CIDR range. (#86578, @tnqn) [SIG Network]
• Improves performance of the node authorizer (#87696, @liggitt) [SIG Auth]
• Iptables/userspace proxy: improve performance by getting local addresses only once per sync loop, instead of for every external IP (#85617, @andrewsykim) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Network]
• Kube-aggregator: always sets unavailableGauge metric to reflect the current state of a service. (#87778, @p0lyn0mial) [SIG API Machinery]
• Kubeadm allows to configure single-stack clusters if dual-stack is enabled (#87453, @aojea) [SIG API Machinery, Cluster Lifecycle and Network]
• Kubeadm: 'kubeadm alpha kubelet config download' has been removed, please use 'kubeadm upgrade node phase kubelet-config' instead (#87944, @SataQiu) [SIG Cluster Lifecycle]
• Kubeadm: remove 'kubeadm upgrade node config' command since it was deprecated in v1.15, please use 'kubeadm upgrade node phase kubelet-config' instead (#87975, @SataQiu) [SIG Cluster Lifecycle]
• Kubectl describe and kubectl top pod will return a message saying "No resources found" or "No resources found in namespace" if there are no results to display. (#87527, @brianpursley) [SIG CLI]
• Kubelet metrics gathered through metrics-server or prometheus should no longer timeout for Windows nodes running more than 3 pods. (#87730, @marosset) [SIG Node, Testing and Windows]
• Kubelet metrics have been changed to buckets. For example the exec/{podNamespace}/{podID}/{containerName} is now just exec. (#87913, @cheftako) [SIG Node]
• Limit number of instances in a single update to GCE target pool to 1000. (#87881, @wojtek-t) [SIG Cloud Provider, Network and Scalability]
• Make Azure clients only retry on specified HTTP status codes (#88017, @feiskyer) [SIG Cloud Provider]
• Pause image contains "Architecture" in non-amd64 images (#87954, @BenTheElder) [SIG Release]
• Pods that are considered for preemption and haven't started don't produce an error log. (#87900, @alculquicondor) [SIG Scheduling]
• Prevent error message from being displayed when running kubectl plugin list and your path includes an empty string (#87633, @brianpursley) [SIG CLI]
• kubectl create clusterrolebinding creates rbac.authorization.k8s.io/v1 object (#85889, @oke-py) [SIG CLI]

Changelog since v1.18.0-alpha.2

Deprecation

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

API Change

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

Feature

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

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

  Throttling request took 1.50705208s, request: GET:

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

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

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

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

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

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

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

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

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

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

Other (Bug, Cleanup or Flake)

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

Changelog since v1.17.0

Action Required

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

Other notable changes

• fix: azure data disk should use same key as os disk by default (#86351, @andyzhangx)
• New flag --show-hidden-metrics-for-version in kube-proxy can be used to show all hidden metrics that deprecated in the previous minor release. (#85279, @RainbowMango)
• Remove cluster-monitoring addon (#85512, @serathius)
• Changed core_pattern on COS nodes to be an absolute path. (#86329, @mml)

• The sample-apiserver aggregated conformance test has updated to use the Kubernetes v1.17.0 sample apiserver (#84735, @liggitt)
• The underlying format of the CPUManager state file has changed. Upgrades should be seamless, but any third-party tools that rely on reading the previous format need to be updated. (#84462, @klueska)
• kubernetes will try to acquire the iptables lock every 100 msec during 5 seconds instead of every second. This specially useful for environments using kube-proxy in iptables mode with a high churn rate of services. (#85771, @aojea)
