Changelog since v1.19.2

Changes by Kind

Feature

Kubernetes is now built using go1.15.2
- build: Update to k/repo-infra@v0.1.1 (supports go1.15.2)
- build: Use go-runner:buster-v2.0.1 (built using go1.15.1)
- bazel: Replace --features with Starlark build settings flag
- hack/lib/util.sh: some bash cleanups
  - switched one spot to use kube::logging
  - make kube::util::find-binary return an error when it doesn't find anything so that hack scripts fail fast instead of with '' binary not found errors.
  - this required deleting some genfeddoc stuff. the binary no longer exists in k/k repo since we removed federation/, and I don't see it in https://github.com/kubernetes-sigs/kubefed/ either. I'm assuming that it's gone for good now.
- bazel: output go_binary rule directly from go_binary_conditional_pure
  
  From: @mikedanese: Instead of aliasing. Aliases are annoying in a number of ways. This is specifically bugging me now because they make the action graph harder to analyze programmatically. By using aliases here, we would need to handle potentially aliased go_binary targets and dereference to the effective target.
  
  The comment references an issue with pure = select(...) which appears to be resolved considering this now builds.
- make kube::util::find-binary not dependent on bazel-out/ structure
  
  Implement an aspect that outputs go_build_mode metadata for go binaries, and use that during binary selection. (#94838, @justaugustus) [SIG Architecture, Release and Testing]

Design

Prevent logging of docker config contents if file is malformed (#95346, @sfowl) [SIG Auth and Node]

Bug or Regression

Do not fail sorting empty elements. (#94666, @soltysh) [SIG CLI]
Ensure getPrimaryInterfaceID not panic when network interfaces for Azure VMSS are null (#94802, @nilo19) [SIG Cloud Provider]
Fix azure file migration panic (#94853, @andyzhangx) [SIG Cloud Provider]
Fix bug where loadbalancer deletion gets stuck because of missing resource group #75198 (#93962, @phiphi282) [SIG Cloud Provider]
Fix detach azure disk issue when vm not exist (#95177, @andyzhangx) [SIG Cloud Provider]
Fix etcd_object_counts metric reported by kube-apiserver (#94819, @tkashem) [SIG API Machinery]
Fix network_programming_latency metric reporting for Endpoints/EndpointSlice deletions, where we don't have correct timestamp (#95363, @wojtek-t) [SIG Network and Scalability]
Fix scheduler cache snapshot when a Node is deleted before its Pods (#95153, @alculquicondor) [SIG Scheduling]
Fix the cloudprovider_azure_api_request_duration_seconds metric buckets to correctly capture the latency metrics. Previously, the majority of the calls would fall in the "+Inf" bucket. (#94943, @marwanad) [SIG Cloud Provider and Instrumentation]
Fix: azure disk resize error if source does not exist (#93011, @andyzhangx) [SIG Cloud Provider]
Fix: detach azure disk broken on Azure Stack (#94885, @andyzhangx) [SIG Cloud Provider]
Fixed a bug where improper storage and comparison of endpoints led to excessive API traffic from the endpoints controller (#94937, @damemi) [SIG Apps, Network and Testing]
Fixed a regression that sometimes prevented kubectl portforward to work when TCP and UDP services were configured on the same port (#94728, @amorenoz) [SIG CLI]
Fixes a bug where EndpointSlices would not be recreated after rapid Service recreation. (#94730, @robscott) [SIG Apps, Network and Testing]
Fixes a race condition in kubelet pod handling (#94774, @auxten) [SIG Node]
Gracefully delete nodes when their parent scale set went missing (#95289, @bpineau) [SIG Cloud Provider]
Kubeadm: relax the validation of kubeconfig server URLs. Allow the user to define custom kubeconfig server URLs without erroring out during validation of existing kubeconfig files (e.g. when using external CA mode). (#94816, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: warn but do not error out on missing "ca.key" files for root CA, front-proxy CA and etcd CA, during "kubeadm join --control-plane" if the user has provided all certificates, keys and kubeconfig files which require signing with the given CA keys. (#94988, @neolit123) [SIG Cluster Lifecycle]

Other (Cleanup or Flake)

Changes by Kind

Bug or Regression

Azure: fix a bug that kube-controller-manager would panic if wrong Azure VMSS name is configured (#94306, @knight42) [SIG Cloud Provider]
Build/lib/release: Explicitly use '--platform' in building server images

When we switched to go-runner for building the apiserver, controller-manager, and scheduler server components, we no longer reference the individual architectures in the image names, specifically in the 'FROM' directive of the server image Dockerfiles.

As a result, server images for non-amd64 images copy in the go-runner amd64 binary instead of the go-runner that matches that architecture.

This commit explicitly sets the '--platform=linux/${arch}' to ensure we're pulling the correct go-runner arch from the manifest list.

Before: FROM ${base_image}

After: FROM --platform=linux/${arch} ${base_image} (#94613, @justaugustus) [SIG Release]
Fix a concurrent map writes error in kubelet (#93773, @knight42) [SIG Node]

Changelog since v1.18.0

What’s New (Major Themes)

Deprecation warnings

SIG API Machinery implemented warnings when using deprecated APIs that are visible to kubectl users and API consumers, and metrics visible to cluster administrators. Requests to a deprecated API are returned with a warning containing a target removal release and any replacement API. Warnings can also be returned by admission webhooks, and specified for deprecated versions of custom resources.

Avoiding permanent beta

From Kubernetes 1.20 onwards, SIG Architecture will implement a new policy to transition all REST APIs out of beta within nine months. The idea behind the new policy is to avoid features staying in beta for a long time. Once a new API enters beta, it will have nine months to either:

reach GA, and deprecate the beta, or
have a new beta version (and deprecate the previous beta).

If a REST API reaches the end of that nine-month countdown, then the next Kubernetes release will deprecate that API version. More information can be found on the Kubernetes Blog.

Expanded CLI support for debugging workloads and nodes

SIG CLI expanded on debugging with kubectl to support two new debugging workflows: debugging workloads by creating a copy, and debugging nodes by creating a container in host namespaces. These can be convenient to:

Insert a debug container in clusters that don’t have ephemeral containers enabled
Modify a crashing container for easier debugging by changing its image, for example to busybox, or its command, for example, to sleep 1d so you have time to kubectl exec.
Inspect configuration files on a node's host filesystem

Since these new workflows don’t require any new cluster features, they’re available for experimentation with your existing clusters via kubectl alpha debug. We’d love to hear your feedback on debugging with kubectl. Reach us by opening an issue, visiting #sig-cli or commenting on enhancement #1441.

Structured logging

SIG Instrumentation standardized the structure of log messages and references to Kubernetes objects. Structured logging makes parsing, processing, storing, querying and analyzing logs easier. New methods in the klog library enforce log message structure.

EndpointSlices are now enabled by default

EndpointSlices are an exciting new API that provides a scalable and extensible alternative to the Endpoints API. EndpointSlices track IP addresses, ports, readiness, and topology information for Pods backing a Service.

In Kubernetes 1.19 this feature will be enabled by default with kube-proxy reading from EndpointSlices instead of Endpoints. Although this will mostly be an invisible change, it should result in noticeable scalability improvements in large clusters. It will also enable significant new features in future Kubernetes releases like Topology Aware Routing.

Ingress graduates to General Availability

SIG Network has graduated the widely used Ingress API to general availability in Kubernetes 1.19. This change recognises years of hard work by Kubernetes contributors, and paves the way for further work on future networking APIs in Kubernetes.

seccomp graduates to General Availability

The seccomp (secure computing mode) support for Kubernetes has graduated to General Availability (GA). This feature can be used to increase the workload security by restricting the system calls for a Pod (applies to all containers) or single containers.

Technically this means that a first class seccompProfile field has been added to the Pod and Container securityContext objects:

securityContext:
  seccompProfile:
    type: RuntimeDefault|Localhost|Unconfined # choose one of the three
    localhostProfile: my-profiles/profile-allow.json # only necessary if type == Localhost

The support for seccomp.security.alpha.kubernetes.io/pod and container.seccomp.security.alpha.kubernetes.io/... annotations are now deprecated, and will be removed in Kubernetes v1.22.0. Right now, an automatic version skew handling will convert the new field into the annotations and vice versa. This means there is no action required for converting existing workloads in a cluster.

You can find more information about how to restrict container system calls with seccomp in the new documentation page on Kubernetes.io

Production images moved to community control

As of Kuberenetes v1.19, Kubernetes container images are stored on a community-controlled storage bucket, located at {asia,eu,us}.gcr.io/k8s-artifacts-prod. The k8s.gcr.io vanity domain has been updated to this new bucket. This brings production artifacts under community control.

KubeSchedulerConfiguration graduates to Beta

SIG Scheduling graduates KubeSchedulerConfiguration to Beta. The KubeSchedulerConfiguration feature allows you to tune the algorithms and other settings of the kube-scheduler. You can easily enable or disable specific functionality (contained in plugins) in selected scheduling phases without having to rewrite the rest of the configuration. Furthermore, a single kube-scheduler instance can serve different configurations, called profiles. Pods can select the profile they want to be scheduled under via the .spec.schedulerName field.

CSI Migration - AzureDisk and vSphere (beta)

In-tree volume plugins and all cloud provider dependencies are being moved out of the Kubernetes core. The CSI migration feature allows existing volumes using the legacy APIs to continue to function even when the code has been removed, by routing all the volume operations to the respective CSI driver. The AzureDisk and vSphere implementations of this feature have been promoted to beta.

Storage capacity tracking

Traditionally, the Kubernetes scheduler was based on the assumption that additional persistent storage is available everywhere in the cluster and has infinite capacity. Topology constraints addressed the first point, but up to now pod scheduling was still done without considering that the remaining storage capacity may not be enough to start a new pod. Storage capacity tracking, a new alpha feature, addresses that by adding an API for a CSI driver to report storage capacity and uses that information in the Kubernetes scheduler when choosing a node for a pod. This feature serves as a stepping stone for supporting dynamic provisioning for local volumes and other volume types that are more capacity constrained.

CSI Volume health monitoring

The alpha version of CSI health monitoring is being released with Kubernetes 1.19. This feature enables CSI Drivers to share abnormal volume conditions from the underlying storage systems with Kubernetes so that they can be reported as events on PVCs or Pods. This feature serves as a stepping stone towards programmatic detection and resolution of individual volume health issues by Kubernetes.

General ephemeral volumes

Kubernetes provides volume plugins whose lifecycle is tied to a pod and can be used as scratch space (e.g. the builtin “empty dir” volume type) or to load some data in to a pod (e.g. the builtin ConfigMap and Secret volume types or “CSI inline volumes”). The new generic ephemeral volumes alpha feature allows any existing storage driver that supports dynamic provisioning to be used as an ephemeral volume with the volume’s lifecycle bound to the Pod.

It can be used to provide scratch storage that is different from the root disk, for example persistent memory, or a separate local disk on that node.
All StorageClass parameters for volume provisioning are supported.
All features supported with PersistentVolumeClaims are supported, such as storage capacity tracking, snapshots and restore, and volume resizing.

Immutable Secrets and ConfigMaps (beta)

Secret and ConfigMap volumes can be marked as immutable, which significantly reduces load on the API server if there are many Secret and ConfigMap volumes in the cluster. See ConfigMap and Secret for more information.

CSI Proxy for Windows

The CSI Proxy for Windows is being promoted to beta along with the 1.19 release. This CSI Proxy enables CSI Drivers to run on Windows by allowing containers in Windows to perform privileged storage operations. At beta, the CSI Proxy for Windows supports storage drivers using direct attached disks and SMB.

Dashboard v2

SIG UI has released v2 of the Kubernetes Dashboard add-on. You can find the most recent release in the kubernetes/dashboard repository. Kubernetes Dashboard now includes CRD support, new translations, and an updated version of AngularJS.

Windows containerd support graduates to beta

Initially introduced in Kubernetes 1.18, Windows containerd support goes to Beta on this release. This includes the added support for Windows Server version 2004 (complete version compatibility can be found in the documentation for Windows).

SIG Windows is also including several addition to this release:

Direct Server Return (DSR) mode support, allowing large numbers of services to scale up efficiently
Windows containers now honor CPU limits
Performance improvements for collections of metrics and summary

Increase the Kubernetes support window to one year

As of Kubernetes 1.19, bugfix support via patch releases for a Kubernetes minor release has increased from 9 months to 1 year.

A survey conducted in early 2019 by the working group (WG) Long Term Support (LTS) showed that a significant subset of Kubernetes end-users fail to upgrade within the previous 9-month support period. A yearly support period provides the cushion end-users appear to desire, and is more in harmony with familiar annual planning cycles.

Known Issues

The new storage capacity tracking alpha feature is known to be affected by a limitation of the WaitForFirstConsumer volume binding mode: #94217

Urgent Upgrade Notes

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

ACTION REQUIRED: Switch core master base images (kube-controller-manager) from debian to distroless. If you need Flex Volumes support using scripts, please build your own image with required packages (like bash) (#91329, @dims) [SIG Cloud Provider, Release, Storage and Testing]
ACTION REQUIRED: Support for basic authentication via the --basic-auth-file flag has been removed. Users should migrate to --token-auth-file for similar functionality. (#89069, @enj) [SIG API Machinery]
Azure blob disk feature(kind: Shared, Dedicated) has been deprecated, you should use kind: Managed in kubernetes.io/azure-disk storage class. (#92905, @andyzhangx) [SIG Cloud Provider and Storage]
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]
Kubeadm does not set the deprecated '--cgroup-driver' flag in /var/lib/kubelet/kubeadm-flags.env, it will be set in the kubelet config.yaml. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration (#90513, @SataQiu) [SIG Cluster Lifecycle]
Kubeadm now respects user specified etcd versions in the ClusterConfiguration and properly uses them. If users do not want to stick to the version specified in the ClusterConfiguration, they should edit the kubeadm-config config map and delete it. (#89588, @rosti) [SIG Cluster Lifecycle]
Kubeadm respects resolvConf value set by user even if systemd-resolved service is active. kubeadm no longer sets the flag in '--resolv-conf' in /var/lib/kubelet/kubeadm-flags.env. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration (#90394, @SataQiu) [SIG Cluster Lifecycle]
Kubeadm: Move the "kubeadm init" phase "kubelet-start" later in the init workflow, after the "kubeconfig" phase. This makes kubeadm start the kubelet only after the KubeletConfiguration component config file (/var/lib/kubelet/config.yaml) is generated and solves a problem where init systems like OpenRC cannot crashloop the kubelet service. (#90892, @xphoniex) [SIG Cluster Lifecycle]
The 'kubeadm config upload' command is finally removed after a full GA deprecation cycle. If you still use it, please, use 'kubeadm init phase upload-config' instead (#92610, @rosti) [SIG Cluster Lifecycle]

- RequestedToCapacityRatio args decoding is case sensitive. All fields are affected.
- DefaultPodTopologySpread plugin is renamed to SelectorSpread.
- Unreserve extension point is removed from Profile definition. All Reserve plugins implement an Unreserve call.
- .disablePreemption was removed. Users can disable preemption by disabling the "DefaultPreemption" PostFilter plugin. (#91420, @pancernik) [SIG Scheduling]

Changes by Kind

Deprecation

Added support for vSphere in-tree volumes migration to vSphere CSI driver. The in-tree vSphere Volume plugin will be deprecated and removed in a future release.

Users that self-deploy Kubernetes on vSphere should enable CSIMigration + CSIMigrationvSphere features and install the vSphere CSI Driver (https://github.com/kubernetes-sigs/vsphere-csi-driver) to avoid disruption to existing Pod and PVC objects at that time. Users should start using the vSphere CSI driver directly for any new volumes.

The CSI Migration feature for vSphere Volume also requires minimum vSphere vCenter/ESXi Version to be 7.0u1 and minimum HW Version to be VM version 15.

vSAN raw policy parameter is deprecated for the in-tree vSphere Volume plugin and will be removed in a future release. (#90911, @divyenpatel) [SIG API Machinery, Node and Storage]
Apiextensions.k8s.io/v1beta1 is deprecated in favor of apiextensions.k8s.io/v1 (#90673, @deads2k) [SIG API Machinery]
Apiregistration.k8s.io/v1beta1 is deprecated in favor of apiregistration.k8s.io/v1 (#90672, @deads2k) [SIG API Machinery]
Authentication.k8s.io/v1beta1 and authorization.k8s.io/v1beta1 are deprecated in 1.19 in favor of v1 levels and will be removed in 1.22 (#90458, @deads2k) [SIG API Machinery and Auth]
Autoscaling/v2beta1 is deprecated in favor of autoscaling/v2beta2 (#90463, @deads2k) [SIG Autoscaling]
Coordination.k8s.io/v1beta1 is deprecated in 1.19, targeted for removal in 1.22, use v1 instead. (#90559, @deads2k) [SIG Scalability]
Ensure that volume capability and staging target fields are present in nodeExpansion CSI calls

Behaviour of NodeExpandVolume being called between NodeStage and NodePublish is deprecated for CSI volumes. CSI drivers should support calling NodeExpandVolume after NodePublish if they have node EXPAND_VOLUME capability (#86968, @gnufied) [SIG Storage]
Feat: azure disk migration go beta in 1.19. Feature gates CSIMigration to Beta (on by default) and CSIMigrationAzureDisk to Beta (off by default since it requires installation of the AzureDisk CSI Driver) The in-tree AzureDisk plugin "kubernetes.io/azure-disk" is now deprecated and will be removed in 1.23. Users should enable CSIMigration + CSIMigrationAzureDisk features and install the AzureDisk CSI Driver (https://github.com/kubernetes-sigs/azuredisk-csi-driver) to avoid disruption to existing Pod and PVC objects at that time. Users should start using the AzureDisk CSI Driver directly for any new volumes. (#90896, @andyzhangx) [SIG Cloud Provider and Storage]
Kube-apiserver: the componentstatus API is deprecated. This API provided status of etcd, kube-scheduler, and kube-controller-manager components, but only worked when those components were local to the API server, and when kube-scheduler and kube-controller-manager exposed unsecured health endpoints. Instead of this API, etcd health is included in the kube-apiserver health check and kube-scheduler/kube-controller-manager health checks can be made directly against those components' health endpoints. (#93570, @liggitt) [SIG API Machinery, Apps and Cluster Lifecycle]
Kubeadm: kubeadm config view command has been deprecated and will be removed in a feature release, please use kubectl get cm -o yaml -n kube-system kubeadm-config to get the kubeadm config directly (#92740, @SataQiu) [SIG Cluster Lifecycle]
Kubeadm: deprecate the "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io. (#92881, @neolit123) [SIG Cluster Lifecycle]
Kubeadm: deprecate the feature --experimental-kustomize in favor of --experimental-patches. The supported patch formats are the same as "kubectl patch". They are read as files from a directory and can be applied to kubeadm components during init/join/upgrade. Only patching of static Pods is supported for the time being. (#92017, @neolit123)
Kubeadm: remove the deprecated "--use-api" flag for "kubeadm alpha certs renew" (#90143, @neolit123) [SIG Cluster Lifecycle]
Kubernetes no longer supports building hyperkube images (#88676, @dims) [SIG Cluster Lifecycle and Release]

API Change

A new alpha-level field, SupportsFsGroup, has been introduced for CSIDrivers to allow them to specify whether they support volume ownership and permission modifications. The CSIVolumeSupportFSGroup feature gate must be enabled to allow this field to be used. (#92001, @huffmanca) [SIG API Machinery, CLI and Storage]
Added pod version skew strategy for seccomp profile to synchronize the deprecated annotations with the new API Server fields. Please see the corresponding section in the KEP for more detailed explanations. (#91408, @saschagrunert) [SIG Apps, Auth, CLI and Node]
Adds the ability to disable Accelerator/GPU metrics collected by Kubelet (#91930, @RenaudWasTaken) [SIG Node]

CertificateSigningRequest API conditions were updated:
- a status field was added; this field defaults to True, and may only be set to True for Approved, Denied, and Failed conditions
- a lastTransitionTime field was added
- a Failed condition type was added to allow signers to indicate permanent failure; this condition can be added via the certificatesigningrequests/status subresource.
- Approved and Denied conditions are mutually exclusive
- Approved, Denied, and Failed conditions can no longer be removed from a CSR (#90191, @liggitt) [SIG API Machinery, Apps, Auth, CLI and Node]
Cluster admins can now turn off /logs endpoint in kubelet by setting enableSystemLogHandler to false in their kubelet configuration file. enableSystemLogHandler can be set to true only when enableDebuggingHandlers is also set to true. (#87273, @SaranBalaji90) [SIG Node]

Fixed: log timestamps now include trailing zeros to maintain a fixed width (#91207, @iamchuckss) [SIG Apps and Node]
Generic ephemeral volumes, a new alpha feature under the GenericEphemeralVolume feature gate, provide a more flexible alternative to EmptyDir volumes: as with EmptyDir, volumes are created and deleted for each pod automatically by Kubernetes. But because the normal provisioning process is used (PersistentVolumeClaim), storage can be provided by third-party storage vendors and all of the usual volume features work. Volumes don't need to be empt; for example, restoring from snapshot is supported. (#92784, @pohly) [SIG API Machinery, Apps, Auth, CLI, Instrumentation, Node, Scheduling, Storage and Testing]
Go1.14.4 is now the minimum version required for building Kubernetes (#92438, @liggitt) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Release, Storage and Testing]

Kubernetes is now built with golang 1.15.0-rc.1.
- The deprecated, legacy behavior of treating the CommonName field on X.509 serving certificates as a host name when no Subject Alternative Names are present is now disabled by default. It can be temporarily re-enabled by adding the value x509ignoreCN=0 to the GODEBUG environment variable. (#93264, @justaugustus) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Release, Scalability, Storage and Testing]

Resolve regression in metadata.managedFields handling in update/patch requests submitted by older API clients (#91748, @apelisse)
Scheduler: optionally check for available storage capacity before scheduling pods which have unbound volumes (alpha feature with the new CSIStorageCapacity feature gate, only works for CSI drivers and depends on support for the feature in a CSI driver deployment) (#92387, @pohly) [SIG API Machinery, Apps, Auth, Scheduling, Storage and Testing]
Seccomp support has graduated to GA. A new seccompProfile field is added to pod and container securityContext objects. Support for seccomp.security.alpha.kubernetes.io/pod and container.seccomp.security.alpha.kubernetes.io/... annotations is deprecated, and will be removed in v1.22. (#91381, @pjbgf) [SIG Apps, Auth, Node, Release, Scheduling and Testing]
ServiceAppProtocol feature gate is now beta and enabled by default, adding new AppProtocol field to Services and Endpoints. (#90023, @robscott) [SIG Apps and Network]
SetHostnameAsFQDN is a new field in PodSpec. When set to true, the fully qualified domain name (FQDN) of a Pod is set as hostname of its containers. In Linux containers, this means setting the FQDN in the hostname field of the kernel (the nodename field of struct utsname). In Windows containers, this means setting the this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters to FQDN. If a pod does not have FQDN, this has no effect. (#91699, @javidiaz) [SIG Apps, Network, Node and Testing]

Update Golang to v1.14.4 (#88638, @justaugustus) [SIG API Machinery, Cloud Provider, Release and Testing]
Updated the API documentation for Service.Spec.IPFamily to warn that its exact semantics will probably change before the dual-stack feature goes GA, and users should look at ClusterIP or Endpoints, not IPFamily, to figure out if an existing Service is IPv4, IPv6, or dual-stack. (#91527, @danwinship) [SIG Apps and Network]
Users can configure a resource prefix to ignore a group of resources. (#88842, @angao) [SIG Node and Scheduling]
Ingress and IngressClass resources have graduated to networking.k8s.io/v1. Ingress and IngressClass types in the extensions/v1beta1 and networking.k8s.io/v1beta1 API versions are deprecated and will no longer be served in 1.22+. Persisted objects can be accessed via the networking.k8s.io/v1 API. Notable changes in v1 Ingress objects (v1beta1 field names are unchanged):

v1beta1 Scheduler Extender encoding is case-sensitive (v1alpha1/v1alpha2 was case-insensitive), its httpTimeout field uses duration encoding (for example, one second is specified as "1s"), and the enableHttps field in v1alpha1/v1alpha2 was renamed to enableHTTPS. (#91625, @pancernik) [SIG Scheduling]

Feature

A defaultpreemption plugin is registered and enabled in scheduler which replaces the legacy hard-coded Pod preemption logic. (#92049, @Huang-Wei) [SIG Scheduling and Testing]
A new extension point PostFilter is introduced to scheduler framework which runs after Filter phase to resolve scheduling filter failures. A typical implementation is running preemption logic. (#91314, @Huang-Wei) [SIG Scheduling and Testing]
ACTION REQUIRED : In CoreDNS v1.7.0, metrics names have been changed which will be backward incompatible with existing reporting formulas that use the old metrics' names. Adjust your formulas to the new names before upgrading.

Kubeadm now includes CoreDNS version v1.7.0. Some of the major changes include:
- Fixed a bug that could cause CoreDNS to stop updating service records.
- Fixed a bug in the forward plugin where only the first upstream server is always selected no matter which policy is set.
- Remove already deprecated options resyncperiod and upstream in the Kubernetes plugin.
- Includes Prometheus metrics name changes (to bring them in line with standard Prometheus metrics naming convention). They will be backward incompatible with existing reporting formulas that use the old metrics' names.
- The federation plugin (allows for v1 Kubernetes federation) has been removed. More details are available in https://coredns.io/2020/06/15/coredns-1.7.0-release/ (#92651, @rajansandeep) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]
API requests to deprecated versions now receive a warning header in the API response, and cause a metric indicating use of a deprecated API to be published:
- kubectl outputs warnings to stderr, and accepts a --warnings-as-errors option to treat warnings as fatal errors
- k8s.io/client-go outputs warnings to stderr by default; override this per-client by setting config.WarningHandler, or per-process with rest.SetDefaultWarningHandler()
- kube-apiserver publishes apiserver_requested_deprecated_apis gauge metrics set to 1 for deprecated APIs which have been requested, with group, version, resource, subresource, and removed_release labels (#73032, @liggitt) [SIG API Machinery, CLI, Instrumentation and Testing]

Service load balancers no longer exclude nodes marked unschedulable from the candidate nodes. The service load balancer exclusion label should be used instead.

Users upgrading from 1.18 who have cordoned nodes should set the node.kubernetes.io/exclude-from-external-load-balancers label on the impacted nodes before upgrading if they wish those nodes to remain excluded from service load balancers.

Flags should be prefixed with a single dash "-" (0x45) for short form or double dash "--" for long form. Before this change, malformed flags (for example, starting with a non-ascii dash character such as 0x8211: "–") would have been silently treated as positional arguments and ignored.

Changelog since v1.19.0-rc.3

Changes by Kind

Deprecation

Kube-apiserver: the componentstatus API is deprecated. This API provided status of etcd, kube-scheduler, and kube-controller-manager components, but only worked when those components were local to the API server, and when kube-scheduler and kube-controller-manager exposed unsecured health endpoints. Instead of this API, etcd health is included in the kube-apiserver health check and kube-scheduler/kube-controller-manager health checks can be made directly against those components' health endpoints. (#93570, @liggitt) [SIG API Machinery, Apps and Cluster Lifecycle]

Bug or Regression

A panic in the apiserver caused by the informer-sync health checker is now fixed. (#93600, @ialidzhikov) [SIG API Machinery]
EndpointSliceMirroring controller now copies labels from Endpoints to EndpointSlices. (#93442, @robscott) [SIG Apps and Network]
Kube-apiserver: jsonpath expressions with consecutive recursive descent operators are no longer evaluated for custom resource printer columns (#93408, @joelsmith) [SIG API Machinery]

Other (Cleanup or Flake)

Build: Update to debian-base@v2.1.0 and debian-iptables@v12.1.1 (#93667, @justaugustus) [SIG API Machinery, Release and Testing]

Changes by Kind

API Change

Adds the ability to disable Accelerator/GPU metrics collected by Kubelet (#91930, @RenaudWasTaken) [SIG Node]
Kubernetes is now built with golang 1.15.0-rc.1.
- The deprecated, legacy behavior of treating the CommonName field on X.509 serving certificates as a host name when no Subject Alternative Names are present is now disabled by default. It can be temporarily re-enabled by adding the value x509ignoreCN=0 to the GODEBUG environment variable. (#93264, @justaugustus) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Release, Scalability, Storage and Testing]

Bug or Regression

Azure: per VMSS VMSS VMs cache to prevent throttling on clusters having many attached VMSS (#93107, @bpineau) [SIG Cloud Provider]
Extended DSR loadbalancer feature in winkernel kube-proxy to HNS versions 9.3-9.max, 10.2+ (#93080, @elweb9858) [SIG Network]
Fix instance not found issues when an Azure Node is recreated in a short time (#93316, @feiskyer) [SIG Cloud Provider]

Changelog since v1.19.0-rc.1

Changes by Kind

API Change

A new alpha-level field, SupportsFsGroup, has been introduced for CSIDrivers to allow them to specify whether they support volume ownership and permission modifications. The CSIVolumeSupportFSGroup feature gate must be enabled to allow this field to be used. (#92001, @huffmanca) [SIG API Machinery, CLI and Storage]
The kube-controller-manager managed signers can now have distinct signing certificates and keys. See the help about --cluster-signing-[signer-name]-{cert,key}-file. --cluster-signing-{cert,key}-file is still the default. (#90822, @deads2k) [SIG API Machinery, Apps and Auth]

Feature

Added kube-apiserver metrics: apiserver_current_inflight_request_measures and, when API Priority and Fairness is enable, windowed_request_stats. (#91177, @MikeSpreitzer) [SIG API Machinery, Instrumentation and Testing]
Rename pod_preemption_metrics to preemption_metrics. (#93256, @ahg-g) [SIG Instrumentation and Scheduling]

Bug or Regression

Do not add nodes labeled with kubernetes.azure.com/managed=false to backend pool of load balancer. (#93034, @matthias50) [SIG Cloud Provider]
Do not retry volume expansion if CSI driver returns FailedPrecondition error (#92986, @gnufied) [SIG Node and Storage]
Fix: determine the correct ip config based on ip family (#93043, @aramase) [SIG Cloud Provider]
Fix: initial delay in mounting azure disk & file (#93052, @andyzhangx) [SIG Cloud Provider and Storage]
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]

Other (Cleanup or Flake)

Kube-up: defaults to limiting critical pods to the kube-system namespace to match behavior prior to 1.17 (#93121, @liggitt) [SIG Cloud Provider and Scheduling]
Update Golang to v1.14.5
- Update repo-infra to 0.0.7 (to support go1.14.5 and go1.13.13)
  - Includes:
    - bazelbuild/bazel-toolchains@3.3.2
    - bazelbuild/rules_go@v0.22.7 (#93088, @justaugustus) [SIG Release and Testing]
Update Golang to v1.14.6
- Update repo-infra to 0.0.8 (to support go1.14.6 and go1.13.14)
  - Includes:
    - bazelbuild/bazel-toolchains@3.4.0

Changelog since v1.19.0-rc.0

Urgent Upgrade Notes

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

Azure blob disk feature(kind: Shared, Dedicated) has been deprecated, you should use kind: Managed in kubernetes.io/azure-disk storage class. (#92905, @andyzhangx) [SIG Cloud Provider and Storage]

Changes by Kind

Deprecation

Kubeadm: deprecate the "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io. (#92881, @neolit123) [SIG Cluster Lifecycle]

API Change

Added pod version skew strategy for seccomp profile to synchronize the deprecated annotations with the new API Server fields. Please see the corresponding section in the KEP for more detailed explanations. (#91408, @saschagrunert) [SIG Apps, Auth, CLI and Node]
Custom Endpoints are now mirrored to EndpointSlices by a new EndpointSliceMirroring controller. (#91637, @robscott) [SIG API Machinery, Apps, Auth, Cloud Provider, Instrumentation, Network and Testing]
Generic ephemeral volumes, a new alpha feature under the GenericEphemeralVolume feature gate, provide a more flexible alternative to EmptyDir volumes: as with EmptyDir, volumes are created and deleted for each pod automatically by Kubernetes. But because the normal provisioning process is used (PersistentVolumeClaim), storage can be provided by third-party storage vendors and all of the usual volume features work. Volumes don't need to be empt; for example, restoring from snapshot is supported. (#92784, @pohly) [SIG API Machinery, Apps, Auth, CLI, Instrumentation, Node, Scheduling, Storage and Testing]

Feature

ACTION REQUIRED : In CoreDNS v1.7.0, metrics names have been changed which will be backward incompatible with existing reporting formulas that use the old metrics' names. Adjust your formulas to the new names before upgrading.

Kubeadm now includes CoreDNS version v1.7.0. Some of the major changes include:
- Fixed a bug that could cause CoreDNS to stop updating service records.
- Fixed a bug in the forward plugin where only the first upstream server is always selected no matter which policy is set.
- Remove already deprecated options resyncperiod and upstream in the Kubernetes plugin.
- Includes Prometheus metrics name changes (to bring them in line with standard Prometheus metrics naming convention). They will be backward incompatible with existing reporting formulas that use the old metrics' names.
- The federation plugin (allows for v1 Kubernetes federation) has been removed. More details are available in https://coredns.io/2020/06/15/coredns-1.7.0-release/ (#92651, @rajansandeep) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]
Add tags support for Azure File Driver (#92825, @ZeroMagic) [SIG Cloud Provider and Storage]
Audit events for API requests to deprecated API versions now include a "k8s.io/deprecated": "true" audit annotation. If a target removal release is identified, the audit event includes a "k8s.io/removal-release": "<majorVersion>.<minorVersion>" audit annotation as well. (#92842, @liggitt) [SIG API Machinery and Instrumentation]
Cloud node-controller use InstancesV2 (#91319, @gongguan) [SIG Apps, Cloud Provider, Scalability and Storage]
Kubeadm: deprecate the "--csr-only" and "--csr-dir" flags of the "kubeadm init phase certs" subcommands. Please use "kubeadm alpha certs generate-csr" instead. This new command allows you to generate new private keys and certificate signing requests for all the control-plane components, so that the certificates can be signed by an external CA. (#92183, @wallrj) [SIG Cluster Lifecycle]
Server-side apply behavior has been regularized in the case where a field is removed from the applied configuration. Removed fields which have no other owners are deleted from the live object, or reset to their default value if they have one. Safe ownership transfers, such as the transfer of a replicas field from a user to an HPA without resetting to the default value are documented in Transferring Ownership (#92661, @jpbetz) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Testing]
Set CSIMigrationvSphere feature gates to beta. Users should enable CSIMigration + CSIMigrationvSphere features and install the vSphere CSI Driver (https://github.com/kubernetes-sigs/vsphere-csi-driver) to move workload from the in-tree vSphere plugin "kubernetes.io/vsphere-volume" to vSphere CSI Driver.

Requires: vSphere vCenter/ESXi Version: 7.0u1, HW Version: VM version 15 (#92816, @divyenpatel) [SIG Cloud Provider and Storage]
Support a smooth upgrade from client-side apply to server-side apply without conflicts, as well as support the corresponding downgrade. (#90187, @julianvmodesto) [SIG API Machinery and Testing]
Trace output in apiserver logs is more organized and comprehensive. Traces are nested, and for all non-long running request endpoints, the entire filter chain is instrumented (e.g. authentication check is included). (#88936, @jpbetz) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Scheduling]
kubectl alpha debug now supports debugging nodes by creating a debugging container running in the node's host namespaces. (#92310, @verb) [SIG CLI]

Failing Test

Kube-proxy iptables min-sync-period defaults to 1 sec. Previously, it was 0. (#92836, @aojea) [SIG Network]

Bug or Regression

Dockershim security: pod sandbox now always run with no-new-privileges and runtime/default seccomp profile dockershim seccomp: custom profiles can now have smaller seccomp profiles when set at pod level (#90948, @pjbgf) [SIG Node]
Eviction requests for pods that have a non-zero DeletionTimestamp will always succeed (#91342, @michaelgugino) [SIG Apps]
Fix detection of image filesystem, disk metrics for devicemapper, detection of OOM Kills on 5.0+ linux kernels. (#92919, @dashpole) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Node]
Fixed memory leak in endpointSliceTracker (#92838, @tnqn) [SIG Apps and Network]
Kube-aggregator certificates are dynamically loaded on change from disk (#92791, @p0lyn0mial) [SIG API Machinery]
Kube-up now includes CoreDNS version v1.7.0. Some of the major changes include:
- Fixed a bug that could cause CoreDNS to stop updating service records.
- Fixed a bug in the forward plugin where only the first upstream server is always selected no matter which policy is set.
- Remove already deprecated options resyncperiod and upstream in the Kubernetes plugin.
- Includes Prometheus metrics name changes (to bring them in line with standard Prometheus metrics naming convention). They will be backward incompatible with existing reporting formulas that use the old metrics' names.
- The federation plugin (allows for v1 Kubernetes federation) has been removed. More details are available in https://coredns.io/2020/06/15/coredns-1.7.0-release/ (#92718, @rajansandeep) [SIG Cloud Provider]
The apiserver 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]
The terminationGracePeriodSeconds from pod spec is respected for the mirror pod. (#92442, @tedyu) [SIG Node and Testing]

Other (Cleanup or Flake)

--cache-dir sets cache directory for both http and discovery, defaults to $HOME/.kube/cache (#92910, @soltysh) [SIG API Machinery and CLI]
Fix: license issue in blob disk feature (#92824, @andyzhangx) [SIG Cloud Provider]

Fixed several bugs involving the IPFamily field when creating or updating services in clusters with the IPv6DualStack feature gate enabled.

Beware that the behavior of the IPFamily field is strange and inconsistent and will likely be changed before the dual-stack feature goes GA. Users should treat the field as "write-only" for now and should not make any assumptions about a service based on its current IPFamily value. (#91400, @danwinship) [SIG Apps and Network]

Changelog since v1.19.0-alpha.3

Urgent Upgrade Notes

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

ACTION REQUIRED : Switch core master base images (kube-controller-manager) from debian to distroless. If you need Flex Volumes support using scripts, please build your own image with required packages (like bash) (#91329, @dims) [SIG Cloud Provider, Release, Storage and Testing]
Kubeadm: Move the "kubeadm init" phase "kubelet-start" later in the init workflow, after the "kubeconfig" phase. This makes kubeadm start the kubelet only after the KubeletConfiguration component config file (/var/lib/kubelet/config.yaml) is generated and solves a problem where init systems like OpenRC cannot crashloop the kubelet service. (#90892, @xphoniex) [SIG Cluster Lifecycle]

Urgent Upgrade Notes

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

Kubeadm does not set the deprecated '--cgroup-driver' flag in /var/lib/kubelet/kubeadm-flags.env, it will be set in the kubelet config.yaml. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration (#90513, @SataQiu) [SIG Cluster Lifecycle]
Kubeadm respects resolvConf value set by user even if systemd-resolved service is active. kubeadm no longer sets the flag in '--resolv-conf' in /var/lib/kubelet/kubeadm-flags.env. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration (#90394, @SataQiu) [SIG Cluster Lifecycle]

Kubeadm: during 'upgrade apply', if the kube-proxy ConfigMap is missing, assume that kube-proxy should not be upgraded. Same applies to a missing kube-dns/coredns ConfigMap for the DNS server addon. Note that this is a temporary workaround until 'upgrade apply' supports phases. Once phases are supported the kube-proxy/dns upgrade should be skipped manually.

Changelog since v1.19.0-alpha.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]
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 client-go user. Set --server, --kubeconfig or KUBECONFIG to make it work in kubectl. (#86173, @soltysh) [SIG API Machinery, 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 Cloud Provider now supports using Azure network resources (Virtual Network, Load Balancer, Public IP, Route Table, Network Security Group, etc.) in different AAD Tenant and Subscription than those for the Kubernetes cluster.
