## Changelog since v1.20.13

## Changes by Kind

### Bug or Regression

- Ensure Pods are removed from the scheduler cache when the scheduler misses deletion events due to transient errors ([#106695](https://github.com/kubernetes/kubernetes/pull/106695), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]
- Fix: skip instance not found when decoupling vmss from lb ([#105834](https://github.com/kubernetes/kubernetes/pull/105834), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]
- Fixed SELinux relabeling of CSI volumes after CSI driver failure. ([#106554](https://github.com/kubernetes/kubernetes/pull/106554), [@jsafrane](https://github.com/jsafrane)) [SIG Node and Storage]
- Kubeadm: allow the "certs check-expiration" command to not require the existence of the cluster CA key (ca.key file) when checking the expiration of managed certificates in kubeconfig files. ([#106927](https://github.com/kubernetes/kubernetes/pull/106927), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: during execution of the "check expiration" command, treat the etcd CA as external if there is a missing etcd CA key file (etcd/ca.key) and perform the proper validation on certificates signed by the etcd CA. Additionally, make sure that the CA for all entries in the output table is included - for both certificates on disk and in kubeconfig files. ([#106923](https://github.com/kubernetes/kubernetes/pull/106923), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Scheduler's assumed pods have 2min instead of 30s to receive nodeName pod updates ([#106686](https://github.com/kubernetes/kubernetes/pull/106686), [@ahg-g](https://github.com/ahg-g)) [SIG Scheduling]

## Changelog since v1.20.10

## Important Security Information

This release contains changes that address the following vulnerabilities:

### CVE-2021-25741: Symlink Exchange Can Allow Host Filesystem Access

A security issue was discovered in Kubernetes where a user may be able to
create a container with subpath volume mounts to access files &
directories outside of the volume, including on the host filesystem.

**Affected Versions**:
  - kubelet v1.22.0 - v1.22.1
  - kubelet v1.21.0 - v1.21.4
  - kubelet v1.20.0 - v1.20.10
  - kubelet <= v1.19.14

**Fixed Versions**:
  - kubelet v1.22.2
  - kubelet v1.21.5
  - kubelet v1.20.11
  - kubelet v1.19.15

This vulnerability was reported by Fabricio Voznika and Mark Wolters of Google.

**CVSS Rating:** High (8.8) [CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

## Changes by Kind

### Bug or Regression

- Fix: skip case sensitivity when checking Azure NSG rules
  fix: ensure InstanceShutdownByProviderID return false for creating Azure VMs ([#104448](https://github.com/kubernetes/kubernetes/pull/104448), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]
- Kube-proxy: delete stale conntrack UDP entries for loadbalancer ingress IP. ([#104152](https://github.com/kubernetes/kubernetes/pull/104152), [@aojea](https://github.com/aojea)) [SIG Network]
- Metrics changes: Fix exposed buckets of `scheduler_volume_scheduling_duration_seconds_bucket` metric ([#100720](https://github.com/kubernetes/kubernetes/pull/100720), [@dntosas](https://github.com/dntosas)) [SIG Apps, Instrumentation, Scheduling and Storage]
- Pass additional flags to subpath mount to avoid flakes in certain conditions ([#104348](https://github.com/kubernetes/kubernetes/pull/104348), [@mauriciopoppe](https://github.com/mauriciopoppe)) [SIG Storage]
- When using `kubectl replace` (or the equivalent API call) on a Service, the caller no longer needs to do a read-modify-write cycle to fetch the allocated values for `.spec.clusterIP` and `.spec.ports[].nodePort`.  Instead the API server will automatically carry these forward from the original object when the new object does not specify them. ([#104674](https://github.com/kubernetes/kubernetes/pull/104674), [@thockin](https://github.com/thockin)) [SIG Network]

### Other (Cleanup or Flake)

- Kube-apiserver: sets an upper-bound on the lifetime of idle keep-alive connections and time to read the headers of incoming requests ([#103958](https://github.com/kubernetes/kubernetes/pull/103958), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Node]

## Changelog since v1.20.8

## Changes by Kind

### Feature

- Kubernetes 1.20.x is now built using Go 1.15.14 ([#103677](https://github.com/kubernetes/kubernetes/pull/103677), [@puerco](https://github.com/puerco)) [SIG Cloud Provider, Instrumentation, Release and Testing]
- Updates the following images to pick up CVE fixes:
  - `debian` to v1.8.0
  - `debian-iptables` to v1.6.5
  - `setcap` to v2.0.3 ([#103235](https://github.com/kubernetes/kubernetes/pull/103235), [@thejoycekung](https://github.com/thejoycekung)) [SIG API Machinery, Release and Testing]

### Bug or Regression

## Changelog since v1.20.7

## Changes by Kind

### Feature

- Kubernetes is now built using Go 1.15.13 ([#102786](https://github.com/kubernetes/kubernetes/pull/102786), [@thejoycekung](https://github.com/thejoycekung)) [SIG Cloud Provider, Instrumentation, Release and Testing]

### Failing Test

- Fixes the `should receive events on concurrent watches in same order` conformance test to work properly on clusters that auto-create additional configmaps in namespaces ([#101950](https://github.com/kubernetes/kubernetes/pull/101950), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

### Bug or Regression

- Added jitter factor to lease controller that better smears load on kube-apiserver over time. ([#101652](https://github.com/kubernetes/kubernetes/pull/101652), [@marseel](https://github.com/marseel)) [SIG API Machinery and Scalability]

- Kubeadm: remove the "ephemeral_storage" request from the etcd static pod that kubeadm deploys on stacked etcd control plane nodes. This request has caused sporadic failures on some setups due to a problem in the kubelet with cadvisor and the LocalStorageCapacityIsolation feature gate. See this issue for more details: https://github.com/kubernetes/kubernetes/issues/99305 ([#102673](https://github.com/kubernetes/kubernetes/pull/102673), [@jackfrancis](https://github.com/jackfrancis)) [SIG Cluster Lifecycle]

## Changelog since v1.20.5

## Important Security Information

This release contains changes that address the following vulnerabilities:

### CVE-2021-25735: Validating Admission Webhook does not observe some previous fields

A security issue was discovered in kube-apiserver that could allow node
updates to bypass a Validating Admission Webhook. You are only affected
by this vulnerability if you run a Validating Admission Webhook for Nodes
that denies admission based at least partially on the old state of the
Node object.

**Note**: This only impacts validating admission plugins that rely on old
values in certain fields, and does not impact calls from kubelet that go
through the built-in NodeRestriction admission plugin.

**Affected Versions**:
  - kube-apiserver v1.20.0 - v1.20.5
  - kube-apiserver v1.19.0 - v1.19.9
  - kube-apiserver <= v1.18.17

**Fixed Versions**:
  - kube-apiserver v1.21.0
  - kube-apiserver v1.20.6
  - kube-apiserver v1.19.10
  - kube-apiserver v1.18.18

This vulnerability was reported by Rogerio Bastos & Ari Lima from RedHat


**CVSS Rating:** Medium (6.5) [CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H)

## Changelog since v1.20.2

## Changes by Kind

### API Change

- Kubernetes is now built using go1.15.8 ([#98962](https://github.com/kubernetes/kubernetes/pull/98962), [@cpanato](https://github.com/cpanato)) [SIG Cloud Provider, Instrumentation, Release and Testing]

### Failing Test

- Kubelet: the HostPort implementation in dockershim was not taking into consideration the HostIP field, causing that the same HostPort can not be used with different IP addresses.
  This bug causes the conformance test "HostPort validates that there is no conflict between pods with same hostPort but different hostIP and protocol" to fail. ([#98838](https://github.com/kubernetes/kubernetes/pull/98838), [@aojea](https://github.com/aojea)) [SIG Network and Node]

### Bug or Regression

- Aggregate errors when putting vmss ([#98350](https://github.com/kubernetes/kubernetes/pull/98350), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]
- Avoid marking node as Ready until node has synced with API servers at least once ([#97995](https://github.com/kubernetes/kubernetes/pull/97995), [@ehashman](https://github.com/ehashman)) [SIG Node]
- Cleanup subnet in frontend IP configs to prevent huge subnet request bodies in some scenarios. ([#98132](https://github.com/kubernetes/kubernetes/pull/98132), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]
- Fix CSI-migrated inline EBS volumes failing to mount if their volumeID is prefixed by aws:// ([#96821](https://github.com/kubernetes/kubernetes/pull/96821), [@wongma7](https://github.com/wongma7)) [SIG Storage]
- Fix azure file migration issue ([#97877](https://github.com/kubernetes/kubernetes/pull/97877), [@andyzhangx](https://github.com/andyzhangx)) [SIG Auth, Cloud Provider and Storage]
- Fix kubectl-convert import known versions ([#97754](https://github.com/kubernetes/kubernetes/pull/97754), [@wzshiming](https://github.com/wzshiming)) [SIG CLI and Testing]
- Fix the description of command line flags that can override --config ([#98786](https://github.com/kubernetes/kubernetes/pull/98786), [@changshuchao](https://github.com/changshuchao)) [SIG Scheduling]
- Fix the panic when kubelet registers if a node object already exists with no Status.Capacity or Status.Allocatable ([#97803](https://github.com/kubernetes/kubernetes/pull/97803), [@TeddyAndrieux](https://github.com/TeddyAndrieux)) [SIG Node]
- Fix the regression with the slow pods termination. Before this fix pods may take an additional time to terminate - up to one minute. Reversing the change that ensured that CNI resources cleaned up when the pod is removed on API server. ([#97980](https://github.com/kubernetes/kubernetes/pull/97980), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev)) [SIG Node]
- Fix to recover CSI volumes from certain dangling attachments ([#96617](https://github.com/kubernetes/kubernetes/pull/96617), [@yuga711](https://github.com/yuga711)) [SIG Apps and Storage]
- Fixed a bug that the kubelet cannot start on BtrfS. ([#98014](https://github.com/kubernetes/kubernetes/pull/98014), [@gjkim42](https://github.com/gjkim42)) [SIG Node]

- Fixed provisioning of Cinder volumes migrated to CSI when StorageClass with AllowedTopologies was used. ([#98311](https://github.com/kubernetes/kubernetes/pull/98311), [@jsafrane](https://github.com/jsafrane)) [SIG Storage]
- Fixes a panic in the disruption budget controller for PDB objects with invalid selectors ([#98775](https://github.com/kubernetes/kubernetes/pull/98775), [@ialidzhikov](https://github.com/ialidzhikov)) [SIG Apps]
- Fixes connection errors when using `--volume-host-cidr-denylist` or `--volume-host-allow-local-loopback` ([#98436](https://github.com/kubernetes/kubernetes/pull/98436), [@liggitt](https://github.com/liggitt)) [SIG Network and Storage]
- Kubeadm: get k8s CI version markers from k8s infra bucket ([#98836](https://github.com/kubernetes/kubernetes/pull/98836), [@hasheddan](https://github.com/hasheddan)) [SIG Cluster Lifecycle and Release]
- Kubelet should ignore cgroup driver check on Windows node. ([#98383](https://github.com/kubernetes/kubernetes/pull/98383), [@pacoxu](https://github.com/pacoxu)) [SIG Node]

## Changelog since v1.19.0

## What's New (Major Themes)

### Dockershim deprecation

Docker as an underlying runtime is being deprecated. Docker-produced images will continue to work in your cluster with all runtimes, as they always have.
The Kubernetes community [has written a blog post about this in detail](https://blog.k8s.io/2020/12/02/dont-panic-kubernetes-and-docker/) with [a dedicated FAQ page for it](https://blog.k8s.io/2020/12/02/dockershim-faq/).

### External credential provider for client-go

The client-go credential plugins can now be passed in the current cluster information via the `KUBERNETES_EXEC_INFO` environment variable. Learn more about this on [client-go credential plugins documentation](https://docs.k8s.io/reference/access-authn-authz/authentication/#client-go-credential-plugins/).

### CronJob controller v2 is available through feature gate

An alternative implementation of the `CronJob` controller is now available as an alpha feature in this release, which has experimental performance improvement by using informers instead of polling. While this will be the default behavior in the future, you can [try them in this release through a feature gate](https://docs.k8s.io/concepts/workloads/controllers/cron-jobs/).

### PID Limits graduates to General Availability

PID Limits features are now generally available on both `SupportNodePidsLimit` (node-to-pod PID isolation) and `SupportPodPidsLimit` (ability to limit PIDs per pod), after being enabled-by-default in beta stage for a year.

### API Priority and Fairness graduates to Beta

Initially introduced in 1.18, Kubernetes 1.20 now enables API Priority and Fairness (APF) by default. This allows `kube-apiserver` to [categorize incoming requests by priority levels](https://docs.k8s.io/concepts/cluster-administration/flow-control/).

### IPv4/IPv6 run

IPv4/IPv6 dual-stack has been reimplemented for 1.20 to support dual-stack Services, based on user and community feedback. If your cluster has dual-stack enabled, you can create Services which can use IPv4, IPv6, or both, and you can change this setting for existing Services. Details are available in updated [IPv4/IPv6 dual-stack docs](https://docs.k8s.io/concepts/services-networking/dual-stack/), which cover the nuanced array of options.

We expect this implementation to progress from alpha to beta and GA in coming releases, so we’re eager to have you comment about your dual-stack experiences in [#k8s-dual-stack](https://kubernetes.slack.com/messages/k8s-dual-stack) or in [enhancements #563](https://features.k8s.io/563). 

### go1.15.5

go1.15.5 has been integrated into the Kubernetes project as of this release, [including other infrastructure related updates on this effort](https://github.com/kubernetes/kubernetes/pull/95776).

### CSI Volume Snapshot graduates to General Availability

CSI Volume Snapshot moves to GA in the 1.20 release. This feature provides a standard way to trigger volume snapshot operations in Kubernetes and allows Kubernetes users to incorporate snapshot operations in a portable manner on any Kubernetes environment regardless of supporting underlying storage providers.
Additionally, these Kubernetes snapshot primitives act as basic building blocks that unlock the ability to develop advanced, enterprise-grade, storage administration features for Kubernetes: including application or cluster level backup solutions.
Note that snapshot support will require Kubernetes distributors to bundle the Snapshot controller, Snapshot CRDs, and validation webhook. In addition, a CSI driver supporting the snapshot functionality must also be deployed on the cluster.

### Non-recursive Volume Ownership (FSGroup) graduates to Beta

By default, the `fsgroup` setting, if specified, recursively updates permissions for every file in a volume on every mount. This can make mount, and pod startup, very slow if the volume has many files. 
This setting enables a pod to specify a `PodFSGroupChangePolicy` that indicates that volume ownership and permissions will be changed only when permission and ownership of the root directory do not match with expected permissions on the volume.

### CSIDriver policy for FSGroup graduates to Beta

The FSGroup's CSIDriver Policy is now beta in 1.20. This allows CSIDrivers to explicitly indicate if they want Kubernetes to manage permissions and ownership for their volumes via `fsgroup`. 

### Security Improvements for CSI Drivers (Alpha)

In 1.20, we introduce a new alpha feature `CSIServiceAccountToken`. This feature allows CSI drivers to impersonate the pods that they mount the volumes for. This improves the security posture in the mounting process where the volumes are ACL’ed on the pods’ service account without handing out unnecessary permissions to the CSI drivers’ service account. This feature is especially important for secret-handling CSI drivers, such as the secrets-store-csi-driver. Since these tokens can be rotated and short-lived, this feature also provides a knob for CSI drivers to receive `NodePublishVolume` RPC calls periodically with the new token. This knob is also useful when volumes are short-lived, e.g. certificates.

### Introducing Graceful Node Shutdown (Alpha)

The `GracefulNodeShutdown` feature is now in Alpha. This allows kubelet to be aware of node system shutdowns, enabling graceful termination of pods during a system shutdown. This feature can be [enabled through feature gate](https://docs.k8s.io/concepts/architecture/nodes/#graceful-node-shutdown).

### Runtime log sanitation

Logs can now be configured to use runtime protection from leaking sensitive data. [Details for this experimental feature is available in documentation](https://docs.k8s.io/concepts/cluster-administration/system-logs/#log-sanitization).

### Pod resource metrics

On-demand metrics calculation is now available through `/metrics/resources`. [When enabled](
https://docs.k8s.io/concepts/cluster-administration/system-metrics#kube-scheduler-metrics), the endpoint will report the requested resources and the desired limits of all running pods.

### Introducing `RootCAConfigMap`

`RootCAConfigMap` graduates to Beta, separating from `BoundServiceAccountTokenVolume`. The `kube-root-ca.crt` ConfigMap is now available to every namespace, by default. It contains the Certificate Authority bundle for verify kube-apiserver connections.

### `kubectl debug` graduates to Beta

`kubectl alpha debug` graduates from alpha to beta in 1.20, becoming `kubectl debug`.
`kubectl debug` provides support for common debugging workflows directly from kubectl. Troubleshooting scenarios supported in this release of `kubectl` include:
Troubleshoot workloads that crash on startup by creating a copy of the pod that uses a different container image or command.
Troubleshoot distroless containers by adding a new container with debugging tools, either in a new copy of the pod or using an ephemeral container. (Ephemeral containers are an alpha feature that are not enabled by default.)
Troubleshoot on a node by creating a container running in the host namespaces and with access to the host’s filesystem.
Note that as a new builtin command, `kubectl debug` takes priority over any `kubectl` plugin named “debug”. You will need to rename the affected plugin.
Invocations using `kubectl alpha debug` are now deprecated and will be removed in a subsequent release. Update your scripts to use `kubectl debug` instead of `kubectl alpha debug`!
For more information about kubectl debug, see [Debugging Running Pods](https://kubernetes.io/docs/tasks/debug-application-cluster/debug-running-pod/) on the Kubernetes website, kubectl help debug, or reach out to SIG CLI by visiting [#sig-cli](https://kubernetes.slack.com/messages/sig-cli) or commenting on [enhancement #1441](https://features.k8s.io/1441).

### Removing deprecated flags in kubeadm

`kubeadm` applies a number of deprecations and removals of deprecated features in this release. More details are available in the Urgent Upgrade Notes and Kind / Deprecation sections.

### Pod Hostname as FQDN graduates to Beta

Previously introduced in 1.19 behind a feature gate, `SetHostnameAsFQDN` is now enabled by default. More details on this behavior are available in [documentation for DNS for Services and Pods](https://docs.k8s.io/concepts/services-networking/dns-pod-service/#pod-sethostnameasfqdn-field)

### `TokenRequest` / `TokenRequestProjection` graduates to General Availability

Service account tokens bound to a pod is now a stable feature. The feature gates will be removed in 1.21 release. For more information, refer to notes below on the changelogs.

### RuntimeClass feature graduates to General Availability.

The `node.k8s.io` API groups are promoted from `v1beta1` to `v1`. `v1beta1` is now deprecated and will be removed in a future release, please start using `v1`. ([#95718](https://github.com/kubernetes/kubernetes/pull/95718), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev)) [SIG Apps, Auth, Node, Scheduling and Testing]

### Cloud Controller Manager now exclusively shipped by Cloud Provider

Kubernetes will no longer ship an instance of the Cloud Controller Manager binary. Each Cloud Provider is expected to ship their own instance of this binary. Details for a Cloud Provider to create an instance of such a binary can be found [here](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/cloud-provider/sample). Anyone with questions on building a Cloud Controller Manager should reach out to SIG Cloud Provider. Questions about the Cloud Controller Manager on a Managed Kubernetes solution should go to the relevant Cloud Provider. Questions about the Cloud Controller Manager on a non managed solution can be brought up with SIG Cloud Provider.

## Known Issues

### Summary API in kubelet doesn't have accelerator metrics
Currently, cadvisor_stats_provider provides AcceleratorStats but cri_stats_provider does not. As a result, when using cri_stats_provider, kubelet's Summary API does not have accelerator metrics. [#96873](https://github.com/kubernetes/kubernetes/pull/96873).

## Urgent Upgrade Notes 

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

- A bug was fixed in kubelet where exec probe timeouts were not respected. This may result in unexpected behavior since the default timeout (if not specified) is `1s` which may be too small for some exec probes. Ensure that pods relying on this behavior are updated to correctly handle probe timeouts. See [configure probe](https://docs.k8s.io/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes) section of the documentation for more details.

  - This change in behavior may be unexpected for some clusters and can be disabled by turning off the `ExecProbeTimeout` feature gate. This gate will be locked and removed in future releases so that exec probe timeouts are always respected. ([#94115](https://github.com/kubernetes/kubernetes/pull/94115), [@andrewsykim](https://github.com/andrewsykim)) [SIG Node and Testing]
- RuntimeClass feature graduates to General Availability. Promote `node.k8s.io` API groups from `v1beta1` to `v1`. `v1beta1` is now deprecated and will be removed in a future release, please start using `v1`. ([#95718](https://github.com/kubernetes/kubernetes/pull/95718), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev)) [SIG Apps, Auth, Node, Scheduling and Testing]
- API priority and fairness graduated to beta. 1.19 servers with APF turned on should not be run in a multi-server cluster with 1.20+ servers. ([#96527](https://github.com/kubernetes/kubernetes/pull/96527), [@adtac](https://github.com/adtac)) [SIG API Machinery and Testing]
- For CSI drivers, kubelet no longer creates the target_path for NodePublishVolume in accordance with the CSI spec. Kubelet also no longer checks if staging and target paths are mounts or corrupted. CSI drivers need to be idempotent and do any necessary mount verification. ([#88759](https://github.com/kubernetes/kubernetes/pull/88759), [@andyzhangx](https://github.com/andyzhangx)) [SIG Storage]
- Kubeadm: http://git.k8s.io/enhancements/keps/sig-cluster-lifecycle/kubeadm/2067-rename-master-label-taint/README.md ([#95382](https://github.com/kubernetes/kubernetes/pull/95382), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
  - The label applied to control-plane nodes "node-role.kubernetes.io/master" is now deprecated and will be removed in a future release after a GA deprecation period.
  - Introduce a new label "node-role.kubernetes.io/control-plane" that will be applied in parallel to "node-role.kubernetes.io/master" until the removal of the "node-role.kubernetes.io/master" label.
  - Make "kubeadm upgrade apply" add the "node-role.kubernetes.io/control-plane" label on existing nodes that only have the "node-role.kubernetes.io/master" label during upgrade.
  - Please adapt your tooling built on top of kubeadm to use the "node-role.kubernetes.io/control-plane" label.
  - The taint applied to control-plane nodes "node-role.kubernetes.io/master:NoSchedule" is now deprecated and will be removed in a future release after a GA deprecation period.
  - Apply toleration for a new, future taint "node-role.kubernetes.io/control-plane:NoSchedule" to the kubeadm CoreDNS / kube-dns managed manifests. Note that this taint is not yet applied to kubeadm control-plane nodes.
  - Please adapt your workloads to tolerate the same future taint preemptively.
    
- Kubeadm: improve the validation of serviceSubnet and podSubnet.
  ServiceSubnet has to be limited in size, due to implementation details, and the mask can not allocate more than 20 bits.
  PodSubnet validates against the corresponding cluster "--node-cidr-mask-size" of the kube-controller-manager, it fail if the values are not compatible.
  kubeadm no longer sets the node-mask automatically on IPv6 deployments, you must check that your IPv6 service subnet mask is compatible with the default node mask /64 or set it accordingly.
  Previously, for IPv6, if the podSubnet had a mask lower than /112, kubeadm calculated a node-mask to be multiple of eight and splitting the available bits to maximise the number used for nodes. ([#95723](https://github.com/kubernetes/kubernetes/pull/95723), [@aojea](https://github.com/aojea)) [SIG Cluster Lifecycle]
- The deprecated flag --experimental-kustomize is now removed from kubeadm commands. Use --experimental-patches instead, which was introduced in 1.19. Migration information available in --help description for --experimental-patches. ([#94871](https://github.com/kubernetes/kubernetes/pull/94871), [@neolit123](https://github.com/neolit123))
- Windows hyper-v container feature gate is deprecated in 1.20 and will be removed in 1.21 ([#95505](https://github.com/kubernetes/kubernetes/pull/95505), [@wawa0210](https://github.com/wawa0210)) [SIG Node and Windows]
- The kube-apiserver ability to serve on an insecure port, deprecated since v1.10, has been removed. The insecure address flags `--address` and `--insecure-bind-address` have no effect in kube-apiserver and will be removed in v1.24. The insecure port flags `--port` and `--insecure-port` may only be set to 0 and will be removed in v1.24. ([#95856](https://github.com/kubernetes/kubernetes/pull/95856), [@knight42](https://github.com/knight42), [SIG API Machinery, Node, Testing])
- Add dual-stack Services (alpha).  This is a BREAKING CHANGE to an alpha API.
  It changes the dual-stack API wrt Service from a single ipFamily field to 3
  fields: ipFamilyPolicy (SingleStack, PreferDualStack, RequireDualStack),
  ipFamilies (a list of families assigned), and clusterIPs (inclusive of
  clusterIP).  Most users do not need to set anything at all, defaulting will
  handle it for them.  Services are single-stack unless the user asks for
  dual-stack.  This is all gated by the "IPv6DualStack" feature gate. ([#91824](https://github.com/kubernetes/kubernetes/pull/91824), [@khenidak](https://github.com/khenidak)) [SIG API Machinery, Apps, CLI, Network, Node, Scheduling and Testing]
- `TokenRequest` and `TokenRequestProjection` are now GA features. The following flags are required by the API server:
  - `--service-account-issuer`, should be set to a URL identifying the API server that will be stable over the cluster lifetime.
  - `--service-account-key-file`, set to one or more files containing one or more public keys used to verify tokens.
  - `--service-account-signing-key-file`, set to a file containing a private key to use to sign service account tokens. Can be the same file given to `kube-controller-manager` with `--service-account-private-key-file`. ([#95896](https://github.com/kubernetes/kubernetes/pull/95896), [@zshihang](https://github.com/zshihang)) [SIG API Machinery, Auth, Cluster Lifecycle]
- kubeadm: make the command "kubeadm alpha kubeconfig user" accept a "--config" flag and remove the following flags:
  - apiserver-advertise-address / apiserver-bind-port: use either localAPIEndpoint from InitConfiguration or controlPlaneEndpoint from ClusterConfiguration.
  - cluster-name: use clusterName from ClusterConfiguration
  - cert-dir: use certificatesDir from ClusterConfiguration ([#94879](https://github.com/kubernetes/kubernetes/pull/94879), [@knight42](https://github.com/knight42)) [SIG Cluster Lifecycle]
- Resolves non-deterministic behavior of the garbage collection controller when ownerReferences with incorrect data are encountered. Events with a reason of `OwnerRefInvalidNamespace` are recorded when namespace mismatches between child and owner objects are detected. The [kubectl-check-ownerreferences](https://github.com/kubernetes-sigs/kubectl-check-ownerreferences) tool can be run prior to upgrading to locate existing objects with invalid ownerReferences.
  - A namespaced object with an ownerReference referencing a uid of a namespaced kind which does not exist in the same namespace is now consistently treated as though that owner does not exist, and the child object is deleted.
  - A cluster-scoped object with an ownerReference referencing a uid of a namespaced kind is now consistently treated as though that owner is not resolvable, and the child object is ignored by the garbage collector. ([#92743](https://github.com/kubernetes/kubernetes/pull/92743), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Apps and Testing]


## Changes by Kind

### Deprecation

- Docker support in the kubelet is now deprecated and will be removed in a future release. The kubelet uses a module called "dockershim" which implements CRI support for Docker and it has seen maintenance issues in the Kubernetes community. We encourage you to evaluate moving to a container runtime that is a full-fledged implementation of CRI (v1alpha1 or v1 compliant) as they become available. ([#94624](https://github.com/kubernetes/kubernetes/pull/94624), [@dims](https://github.com/dims)) [SIG Node]
- Kubeadm: deprecate self-hosting support. The experimental command "kubeadm alpha self-hosting" is now deprecated and will be removed in a future release. ([#95125](https://github.com/kubernetes/kubernetes/pull/95125), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: graduate the "kubeadm alpha certs" command to a parent command "kubeadm certs". The command "kubeadm alpha certs" is deprecated and will be removed in a future release. Please migrate. ([#94938](https://github.com/kubernetes/kubernetes/pull/94938), [@yagonobre](https://github.com/yagonobre)) [SIG Cluster Lifecycle]
- Kubeadm: remove the deprecated "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io. This change also removes the parent command "kubeadm alpha kubelet" as there are no more sub-commands under it for the time being. ([#94668](https://github.com/kubernetes/kubernetes/pull/94668), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: remove the deprecated --kubelet-config flag for the command "kubeadm upgrade node" ([#94869](https://github.com/kubernetes/kubernetes/pull/94869), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubectl: deprecate --delete-local-data ([#95076](https://github.com/kubernetes/kubernetes/pull/95076), [@dougsland](https://github.com/dougsland)) [SIG CLI, Cloud Provider and Scalability]
- Kubelet's deprecated endpoint `metrics/resource/v1alpha1` has been removed, please adopt `metrics/resource`. ([#94272](https://github.com/kubernetes/kubernetes/pull/94272), [@RainbowMango](https://github.com/RainbowMango)) [SIG Instrumentation and Node]
- Removes deprecated scheduler metrics DeprecatedSchedulingDuration, DeprecatedSchedulingAlgorithmPredicateEvaluationSecondsDuration, DeprecatedSchedulingAlgorithmPriorityEvaluationSecondsDuration ([#94884](https://github.com/kubernetes/kubernetes/pull/94884), [@arghya88](https://github.com/arghya88)) [SIG Instrumentation and Scheduling]
- Scheduler alpha metrics binding_duration_seconds and scheduling_algorithm_preemption_evaluation_seconds are deprecated, Both of those metrics are now covered as part of framework_extension_point_duration_seconds, the former as a PostFilter the latter and a Bind plugin. The plan is to remove both in 1.21 ([#95001](https://github.com/kubernetes/kubernetes/pull/95001), [@arghya88](https://github.com/arghya88)) [SIG Instrumentation and Scheduling]
- Support `controlplane` as a valid EgressSelection type in the EgressSelectorConfiguration API. `Master` is deprecated and will be removed in v1.22. ([#95235](https://github.com/kubernetes/kubernetes/pull/95235), [@andrewsykim](https://github.com/andrewsykim)) [SIG API Machinery]
- The v1alpha1 PodPreset API and admission plugin has been removed with no built-in replacement. Admission webhooks can be used to modify pods on creation. ([#94090](https://github.com/kubernetes/kubernetes/pull/94090), [@deads2k](https://github.com/deads2k)) [SIG API Machinery, Apps, CLI, Cloud Provider, Scalability and Testing]


### API Change

- `TokenRequest` and `TokenRequestProjection` features have been promoted to GA. This feature allows generating service account tokens that are not visible in Secret objects and are tied to the lifetime of a Pod object. See https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/#service-account-token-volume-projection for details on configuring and using this feature. The `TokenRequest` and `TokenRequestProjection` feature gates will be removed in v1.21.
  - kubeadm's kube-apiserver Pod manifest now includes the following flags by default "--service-account-key-file", "--service-account-signing-key-file", "--service-account-issuer". ([#93258](https://github.com/kubernetes/kubernetes/pull/93258), [@zshihang](https://github.com/zshihang)) [SIG API Machinery, Auth, Cluster Lifecycle, Storage and Testing]
- A new `nofuzz` go build tag now disables gofuzz support. Release binaries enable this. ([#92491](https://github.com/kubernetes/kubernetes/pull/92491), [@BenTheElder](https://github.com/BenTheElder)) [SIG API Machinery]
- Add WindowsContainerResources and Annotations to CRI-API UpdateContainerResourcesRequest ([#95741](https://github.com/kubernetes/kubernetes/pull/95741), [@katiewasnothere](https://github.com/katiewasnothere)) [SIG Node]
- Add a `serving` and `terminating` condition to the EndpointSlice API.
  `serving` tracks the readiness of endpoints regardless of their terminating state. This is distinct from `ready` since `ready` is only true when pods are not terminating. 
  `terminating` is true when an endpoint is terminating. For pods this is any endpoint with a deletion timestamp. ([#92968](https://github.com/kubernetes/kubernetes/pull/92968), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps and Network]
- Add dual-stack Services (alpha).  This is a BREAKING CHANGE to an alpha API.
  It changes the dual-stack API wrt Service from a single ipFamily field to 3
  fields: ipFamilyPolicy (SingleStack, PreferDualStack, RequireDualStack),
  ipFamilies (a list of families assigned), and clusterIPs (inclusive of
  clusterIP).  Most users do not need to set anything at all, defaulting will
  handle it for them.  Services are single-stack unless the user asks for
  dual-stack.  This is all gated by the "IPv6DualStack" feature gate. ([#91824](https://github.com/kubernetes/kubernetes/pull/91824), [@khenidak](https://github.com/khenidak)) [SIG API Machinery, Apps, CLI, Network, Node, Scheduling and Testing]
- Add support for hugepages to downward API ([#86102](https://github.com/kubernetes/kubernetes/pull/86102), [@derekwaynecarr](https://github.com/derekwaynecarr)) [SIG API Machinery, Apps, CLI, Network, Node, Scheduling and Testing]
- Adds kubelet alpha feature, `GracefulNodeShutdown` which makes kubelet aware of node system shutdowns and result in graceful termination of pods during a system shutdown. ([#96129](https://github.com/kubernetes/kubernetes/pull/96129), [@bobbypage](https://github.com/bobbypage)) [SIG Node]
- AppProtocol is now GA for Endpoints and Services. The ServiceAppProtocol feature gate will be deprecated in 1.21. ([#96327](https://github.com/kubernetes/kubernetes/pull/96327), [@robscott](https://github.com/robscott)) [SIG Apps and Network]
- Automatic allocation of NodePorts for services with type LoadBalancer can now be disabled by setting the (new) parameter
  Service.spec.allocateLoadBalancerNodePorts=false. The default is to allocate NodePorts for services with type LoadBalancer which is the existing behavior. ([#92744](https://github.com/kubernetes/kubernetes/pull/92744), [@uablrek](https://github.com/uablrek)) [SIG Apps and Network]
- Certain fields on  Service objects will be automatically cleared when changing the service's `type` to a mode that does not need those fields.  For example, changing from type=LoadBalancer to type=ClusterIP will clear the NodePort assignments, rather than forcing the user to clear them. ([#95196](https://github.com/kubernetes/kubernetes/pull/95196), [@thockin](https://github.com/thockin)) [SIG API Machinery, Apps, Network and Testing]
- Document that ServiceTopology feature is required to use `service.spec.topologyKeys`. ([#96528](https://github.com/kubernetes/kubernetes/pull/96528), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps]
- EndpointSlice has a new NodeName field guarded by the EndpointSliceNodeName feature gate.
  - EndpointSlice topology field will be deprecated in an upcoming release.

    - 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](https://github.com/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

- 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:

- Resolves non-deterministic behavior of the garbage collection controller when ownerReferences with incorrect data are encountered.

The [kubectl-check-ownerreferences](https://github.com/kubernetes-sigs/kubectl-check-ownerreferences) tool can be run prior to upgrading to locate existing objects with invalid ownerReferences.
  - A namespaced object with an ownerReference referencing a uid of a namespaced kind which does not exist in the same namespace is now consistently treated as though that owner does not exist, and the child object is deleted.
  - A cluster-scoped object with an ownerReference referencing a uid of a namespaced kind is now consistently treated as though that owner is not resolvable, and the child object is ignored by the garbage collector.

## Changelog since v1.20.0-beta.2

## Changes by Kind

### Feature

- Kubernetes is now built using go1.15.5
  - build: Update to k/repo-infra@v0.1.2 (supports go1.15.5) ([#95776](https://github.com/kubernetes/kubernetes/pull/95776), [@justaugustus](https://github.com/justaugustus)) [SIG Cloud Provider, Instrumentation, Release and Testing]

### Failing Test

- Resolves an issue running Ingress conformance tests on clusters which use finalizers on Ingress objects to manage releasing load balancer resources ([#96742](https://github.com/kubernetes/kubernetes/pull/96742), [@spencerhance](https://github.com/spencerhance)) [SIG Network and Testing]
- The Conformance test "validates that there is no conflict between pods with same hostPort but different hostIP and protocol" now validates the connectivity to each hostPort, in addition to the functionality. ([#96627](https://github.com/kubernetes/kubernetes/pull/96627), [@aojea](https://github.com/aojea)) [SIG Scheduling and Testing]

### Bug or Regression

- Bump node-problem-detector version to v0.8.5 to fix OOM detection in with Linux kernels 5.1+ ([#96716](https://github.com/kubernetes/kubernetes/pull/96716), [@tosi3k](https://github.com/tosi3k)) [SIG Cloud Provider, Scalability and Testing]
- Changes to timeout parameter handling in 1.20.0-beta.2 have been reverted to avoid breaking backwards compatibility with existing clients. ([#96727](https://github.com/kubernetes/kubernetes/pull/96727), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]
- Duplicate owner reference entries in create/update/patch requests now get deduplicated by the API server. The client sending the request now receives a warning header in the API response. Clients should stop sending requests with duplicate owner references. The API server may reject such requests as early as 1.24. ([#96185](https://github.com/kubernetes/kubernetes/pull/96185), [@roycaihw](https://github.com/roycaihw)) [SIG API Machinery and Testing]
- Fix: resize Azure disk issue when it's in attached state ([#96705](https://github.com/kubernetes/kubernetes/pull/96705), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]
- Fixed a bug where aggregator_unavailable_apiservice metrics were reported for deleted apiservices. ([#96421](https://github.com/kubernetes/kubernetes/pull/96421), [@dgrisonnet](https://github.com/dgrisonnet)) [SIG API Machinery and Instrumentation]
- Fixes code generation for non-namespaced create subresources fake client test. ([#96586](https://github.com/kubernetes/kubernetes/pull/96586), [@Doude](https://github.com/Doude)) [SIG API Machinery]
- HTTP/2 connection health check is enabled by default in all Kubernetes clients. The feature should work out-of-the-box. If needed, users can tune the feature via the HTTP2_READ_IDLE_TIMEOUT_SECONDS and HTTP2_PING_TIMEOUT_SECONDS environment variables. The feature is disabled if HTTP2_READ_IDLE_TIMEOUT_SECONDS is set to 0. ([#95981](https://github.com/kubernetes/kubernetes/pull/95981), [@caesarxuchao](https://github.com/caesarxuchao)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Node]
- Kubeadm: fix coredns migration should be triggered when there are newdefault configs during kubeadm upgrade ([#96907](https://github.com/kubernetes/kubernetes/pull/96907), [@pacoxu](https://github.com/pacoxu)) [SIG Cluster Lifecycle]
- Reduce volume name length for vSphere volumes ([#96533](https://github.com/kubernetes/kubernetes/pull/96533), [@gnufied](https://github.com/gnufied)) [SIG Storage]
- Resolves a regression in 1.19+ with workloads targeting deprecated beta os/arch labels getting stuck in NodeAffinity status on node startup. ([#96810](https://github.com/kubernetes/kubernetes/pull/96810), [@liggitt](https://github.com/liggitt)) [SIG Node]

## Changelog since v1.20.0-beta.1

## Urgent Upgrade Notes

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

 - A bug was fixed in kubelet where exec probe timeouts were not respected. Ensure that pods relying on this behavior are updated to correctly handle probe timeouts.
  
  This change in behavior may be unexpected for some clusters and can be disabled by turning off the ExecProbeTimeout feature gate. This gate will be locked and removed in future releases so that exec probe timeouts are always respected. ([#94115](https://github.com/kubernetes/kubernetes/pull/94115), [@andrewsykim](https://github.com/andrewsykim)) [SIG Node and Testing]
  - For CSI drivers, kubelet no longer creates the target_path for NodePublishVolume in accordance with the CSI spec. Kubelet also no longer checks if staging and target paths are mounts or corrupted. CSI drivers need to be idempotent and do any necessary mount verification. ([#88759](https://github.com/kubernetes/kubernetes/pull/88759), [@andyzhangx](https://github.com/andyzhangx)) [SIG Storage]
  - Kubeadm:
  - The label applied to control-plane nodes "node-role.kubernetes.io/master" is now deprecated and will be removed in a future release after a GA deprecation period.
  - Introduce a new label "node-role.kubernetes.io/control-plane" that will be applied in parallel to "node-role.kubernetes.io/master" until the removal of the "node-role.kubernetes.io/master" label.
  - Make "kubeadm upgrade apply" add the "node-role.kubernetes.io/control-plane" label on existing nodes that only have the "node-role.kubernetes.io/master" label during upgrade.
  - Please adapt your tooling built on top of kubeadm to use the "node-role.kubernetes.io/control-plane" label.
  
  - The taint applied to control-plane nodes "node-role.kubernetes.io/master:NoSchedule" is now deprecated and will be removed in a future release after a GA deprecation period.
  - Apply toleration for a new, future taint "node-role.kubernetes.io/control-plane:NoSchedule" to the kubeadm CoreDNS / kube-dns managed manifests. Note that this taint is not yet applied to kubeadm control-plane nodes.
  - Please adapt your workloads to tolerate the same future taint preemptively.
  
  For more details see: http://git.k8s.io/enhancements/keps/sig-cluster-lifecycle/kubeadm/2067-rename-master-label-taint/README.md ([#95382](https://github.com/kubernetes/kubernetes/pull/95382), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
 
## Changes by Kind

### Deprecation

- Docker support in the kubelet is now deprecated and will be removed in a future release. The kubelet uses a module called "dockershim" which implements CRI support for Docker and it has seen maintenance issues in the Kubernetes community. We encourage you to evaluate moving to a container runtime that is a full-fledged implementation of CRI (v1alpha1 or v1 compliant) as they become available. ([#94624](https://github.com/kubernetes/kubernetes/pull/94624), [@dims](https://github.com/dims)) [SIG Node]
- Kubectl: deprecate --delete-local-data ([#95076](https://github.com/kubernetes/kubernetes/pull/95076), [@dougsland](https://github.com/dougsland)) [SIG CLI, Cloud Provider and Scalability]

### API Change

- API priority and fairness graduated to beta
  1.19 servers with APF turned on should not be run in a multi-server cluster with 1.20+ servers. ([#96527](https://github.com/kubernetes/kubernetes/pull/96527), [@adtac](https://github.com/adtac)) [SIG API Machinery and Testing]
- Add LoadBalancerIPMode feature gate ([#92312](https://github.com/kubernetes/kubernetes/pull/92312), [@Sh4d1](https://github.com/Sh4d1)) [SIG Apps, CLI, Cloud Provider and Network]

- Add a 'serving' and `terminating` condition to the EndpointSlice API.
  
  `serving` tracks the readiness of endpoints regardless of their terminating state. This is distinct from `ready` since `ready` is only true when pods are not terminating. 
  `terminating` is true when an endpoint is terminating. For pods this is any endpoint with a deletion timestamp. ([#92968](https://github.com/kubernetes/kubernetes/pull/92968), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps and Network]
- Add support for hugepages to downward API ([#86102](https://github.com/kubernetes/kubernetes/pull/86102), [@derekwaynecarr](https://github.com/derekwaynecarr)) [SIG API Machinery, Apps, CLI, Network, Node, Scheduling and Testing]

- AppProtocol is now GA for Endpoints and Services. The ServiceAppProtocol feature gate will be deprecated in 1.21. ([#96327](https://github.com/kubernetes/kubernetes/pull/96327), [@robscott](https://github.com/robscott)) [SIG Apps and Network]
- Automatic allocation of NodePorts for services with type LoadBalancer can now be disabled by setting the (new) parameter
  Service.spec.allocateLoadBalancerNodePorts=false. The default is to allocate NodePorts for services with type LoadBalancer which is the existing behavior. ([#92744](https://github.com/kubernetes/kubernetes/pull/92744), [@uablrek](https://github.com/uablrek)) [SIG Apps and Network]
- Document that ServiceTopology feature is required to use `service.spec.topologyKeys`. ([#96528](https://github.com/kubernetes/kubernetes/pull/96528), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps]
- EndpointSlice has a new NodeName field guarded by the EndpointSliceNodeName feature gate.
  - EndpointSlice topology field will be deprecated in an upcoming release.
  - EndpointSlice "IP" address type is formally removed after being deprecated in Kubernetes 1.17.
  - The discovery.k8s.io/v1alpha1 API is deprecated and will be removed in Kubernetes 1.21. ([#96440](https://github.com/kubernetes/kubernetes/pull/96440), [@robscott](https://github.com/robscott)) [SIG API Machinery, Apps and Network]
- Fewer candidates are enumerated for preemption to improve performance in large clusters ([#94814](https://github.com/kubernetes/kubernetes/pull/94814), [@adtac](https://github.com/adtac)) [SIG Scheduling]
- If BoundServiceAccountTokenVolume is enabled, cluster admins can use metric `serviceaccount_stale_tokens_total` to monitor workloads that are depending on the extended tokens. If there are no such workloads, turn off extended tokens by starting `kube-apiserver` with flag `--service-account-extend-token-expiration=false` ([#96273](https://github.com/kubernetes/kubernetes/pull/96273), [@zshihang](https://github.com/zshihang)) [SIG API Machinery and Auth]
- Introduce alpha support for exec-based container registry credential provider plugins in the kubelet. ([#94196](https://github.com/kubernetes/kubernetes/pull/94196), [@andrewsykim](https://github.com/andrewsykim)) [SIG Node and Release]
- Kube-apiserver now deletes expired kube-apiserver Lease objects:
  - The feature is under feature gate `APIServerIdentity`.
  - A flag is added to kube-apiserver: `identity-lease-garbage-collection-check-period-seconds` ([#95895](https://github.com/kubernetes/kubernetes/pull/95895), [@roycaihw](https://github.com/roycaihw)) [SIG API Machinery, Apps, Auth and Testing]
- Move configurable fsgroup change policy for pods to beta ([#96376](https://github.com/kubernetes/kubernetes/pull/96376), [@gnufied](https://github.com/gnufied)) [SIG Apps and Storage]
- New flag is introduced, i.e. --topology-manager-scope=container|pod. 
  The default value is the "container" scope. ([#92967](https://github.com/kubernetes/kubernetes/pull/92967), [@cezaryzukowski](https://github.com/cezaryzukowski)) [SIG Instrumentation, Node and Testing]

- Reminder: The labels "failure-domain.beta.kubernetes.io/zone" and "failure-domain.beta.kubernetes.io/region" are deprecated in favor of "topology.kubernetes.io/zone" and "topology.kubernetes.io/region" respectively.  All users of the "failure-domain.beta..." labels should switch to the "topology..." equivalents. ([#96033](https://github.com/kubernetes/kubernetes/pull/96033), [@thockin](https://github.com/thockin)) [SIG API Machinery, Apps, CLI, Cloud Provider, Network, Node, Scheduling, Storage and Testing]
- The usage of mixed protocol values in the same LoadBalancer Service is possible if the new feature gate MixedProtocolLBSVC is enabled.
  "action required"
  The feature gate is disabled by default. The user has to enable it for the API Server. ([#94028](https://github.com/kubernetes/kubernetes/pull/94028), [@janosi](https://github.com/janosi)) [SIG API Machinery and Apps]
- This PR will introduce a feature gate CSIServiceAccountToken with two additional fields in `CSIDriverSpec`. ([#93130](https://github.com/kubernetes/kubernetes/pull/93130), [@zshihang](https://github.com/zshihang)) [SIG API Machinery, Apps, Auth, CLI, Network, Node, Storage and Testing]

## Changelog since v1.20.0-beta.0

## Changes by Kind

### Deprecation

- ACTION REQUIRED: The kube-apiserver ability to serve on an insecure port, deprecated since v1.10, has been removed. The insecure address flags `--address` and `--insecure-bind-address` have no effect in kube-apiserver and will be removed in v1.24. The insecure port flags `--port` and `--insecure-port` may only be set to 0 and will be removed in v1.24. ([#95856](https://github.com/kubernetes/kubernetes/pull/95856), [@knight42](https://github.com/knight42)) [SIG API Machinery, Node and Testing]

### API Change

- + `TokenRequest` and `TokenRequestProjection` features have been promoted to GA. This feature allows generating service account tokens that are not visible in Secret objects and are tied to the lifetime of a Pod object. See https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/#service-account-token-volume-projection for details on configuring and using this feature. The `TokenRequest` and `TokenRequestProjection` feature gates will be removed in v1.21.
  + kubeadm's kube-apiserver Pod manifest now includes the following flags by default "--service-account-key-file", "--service-account-signing-key-file", "--service-account-issuer". ([#93258](https://github.com/kubernetes/kubernetes/pull/93258), [@zshihang](https://github.com/zshihang)) [SIG API Machinery, Auth, Cluster Lifecycle, Storage and Testing]
- Certain fields on  Service objects will be automatically cleared when changing the service's `type` to a mode that does not need those fields.  For example, changing from type=LoadBalancer to type=ClusterIP will clear the NodePort assignments, rather than forcing the user to clear them. ([#95196](https://github.com/kubernetes/kubernetes/pull/95196), [@thockin](https://github.com/thockin)) [SIG API Machinery, Apps, Network and Testing]
- Services will now have a `clusterIPs` field to go with `clusterIP`.  `clusterIPs[0]` is a synonym for `clusterIP` and will be synchronized on create and update operations. ([#95894](https://github.com/kubernetes/kubernetes/pull/95894), [@thockin](https://github.com/thockin)) [SIG Network]

### Feature

- A new metric `apiserver_request_filter_duration_seconds` has been introduced that 
  measures request filter latency in seconds. ([#95207](https://github.com/kubernetes/kubernetes/pull/95207), [@tkashem](https://github.com/tkashem)) [SIG API Machinery and Instrumentation]
- Add a new flag to set priority for the kubelet on Windows nodes so that workloads cannot overwhelm the node there by disrupting kubelet process. ([#96051](https://github.com/kubernetes/kubernetes/pull/96051), [@ravisantoshgudimetla](https://github.com/ravisantoshgudimetla)) [SIG Node and Windows]
- Changed: default "Accept: */*" header added to HTTP probes. See https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#http-probes (https://github.com/kubernetes/website/pull/24756) ([#95641](https://github.com/kubernetes/kubernetes/pull/95641), [@fonsecas72](https://github.com/fonsecas72)) [SIG Network and Node]
- Client-go credential plugins can now be passed in the current cluster information via the KUBERNETES_EXEC_INFO environment variable. ([#95489](https://github.com/kubernetes/kubernetes/pull/95489), [@ankeesler](https://github.com/ankeesler)) [SIG API Machinery and Auth]
- Kube-apiserver: added support for compressing rotated audit log files with `--audit-log-compress` ([#94066](https://github.com/kubernetes/kubernetes/pull/94066), [@lojies](https://github.com/lojies)) [SIG API Machinery and Auth]

### Documentation

- Fake dynamic client: document that List does not preserve TypeMeta in UnstructuredList ([#95117](https://github.com/kubernetes/kubernetes/pull/95117), [@andrewsykim](https://github.com/andrewsykim)) [SIG API Machinery]

### Bug or Regression

- Added support to kube-proxy for externalTrafficPolicy=Local setting via Direct Server Return (DSR) load balancers on Windows. ([#93166](https://github.com/kubernetes/kubernetes/pull/93166), [@elweb9858](https://github.com/elweb9858)) [SIG Network]
- Disable watchcache for events ([#96052](https://github.com/kubernetes/kubernetes/pull/96052), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]
- Disabled `LocalStorageCapacityIsolation` feature gate is honored during scheduling. ([#96092](https://github.com/kubernetes/kubernetes/pull/96092), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling]
- Fix bug in JSON path parser where an error occurs when a range is empty ([#95933](https://github.com/kubernetes/kubernetes/pull/95933), [@brianpursley](https://github.com/brianpursley)) [SIG API Machinery]
- Fix k8s.io/apimachinery/pkg/api/meta.SetStatusCondition to update ObservedGeneration ([#95961](https://github.com/kubernetes/kubernetes/pull/95961), [@KnicKnic](https://github.com/KnicKnic)) [SIG API Machinery]
- Fixed a regression which prevented pods with `docker/default` seccomp annotations from being created in 1.19 if a PodSecurityPolicy was in place which did not allow `runtime/default` seccomp profiles. ([#95985](https://github.com/kubernetes/kubernetes/pull/95985), [@saschagrunert](https://github.com/saschagrunert)) [SIG Auth]
- Kubectl: print error if users place flags before plugin name ([#92343](https://github.com/kubernetes/kubernetes/pull/92343), [@knight42](https://github.com/knight42)) [SIG CLI]
- When creating a PVC with the volume.beta.kubernetes.io/storage-provisioner annotation already set, the PV controller might have incorrectly deleted the newly provisioned PV instead of binding it to the PVC, depending on timing and system load. ([#95909](https://github.com/kubernetes/kubernetes/pull/95909), [@pohly](https://github.com/pohly)) [SIG Apps and Storage]

### Other (Cleanup or Flake)

- Kubectl: the `generator` flag of `kubectl autoscale` has been deprecated and has no effect, it will be removed in a feature release ([#92998](https://github.com/kubernetes/kubernetes/pull/92998), [@SataQiu](https://github.com/SataQiu)) [SIG CLI]
- V1helpers.MatchNodeSelectorTerms now accepts just a Node and a list of Terms ([#95871](https://github.com/kubernetes/kubernetes/pull/95871), [@damemi](https://github.com/damemi)) [SIG Apps, Scheduling and Storage]
- `MatchNodeSelectorTerms` function moved to `k8s.io/component-helpers` ([#95531](https://github.com/kubernetes/kubernetes/pull/95531), [@damemi](https://github.com/damemi)) [SIG Apps, Scheduling and Storage]

## Changelog since v1.20.0-alpha.3

## Urgent Upgrade Notes

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

 - Kubeadm: improve the validation of serviceSubnet and podSubnet.
  ServiceSubnet has to be limited in size, due to implementation details, and the mask can not allocate more than 20 bits.
  PodSubnet validates against the corresponding cluster "--node-cidr-mask-size" of the kube-controller-manager, it fail if the values are not compatible.
  kubeadm no longer sets the node-mask automatically on IPv6 deployments, you must check that your IPv6 service subnet mask is compatible with the default node mask /64 or set it accordingly.
  Previously, for IPv6, if the podSubnet had a mask lower than /112, kubeadm calculated a node-mask to be multiple of eight and splitting the available bits to maximise the number used for nodes. ([#95723](https://github.com/kubernetes/kubernetes/pull/95723), [@aojea](https://github.com/aojea)) [SIG Cluster Lifecycle]
  - Windows hyper-v container feature gate is deprecated in 1.20 and will be removed in 1.21 ([#95505](https://github.com/kubernetes/kubernetes/pull/95505), [@wawa0210](https://github.com/wawa0210)) [SIG Node and Windows]
 
## Changes by Kind

### Deprecation

- Support 'controlplane' as a valid EgressSelection type in the EgressSelectorConfiguration API. 'Master' is deprecated and will be removed in v1.22. ([#95235](https://github.com/kubernetes/kubernetes/pull/95235), [@andrewsykim](https://github.com/andrewsykim)) [SIG API Machinery]

### API Change

- Add dual-stack Services (alpha).  This is a BREAKING CHANGE to an alpha API.
  It changes the dual-stack API wrt Service from a single ipFamily field to 3
  fields: ipFamilyPolicy (SingleStack, PreferDualStack, RequireDualStack),
  ipFamilies (a list of families assigned), and clusterIPs (inclusive of
  clusterIP).  Most users do not need to set anything at all, defaulting will
  handle it for them.  Services are single-stack unless the user asks for
  dual-stack.  This is all gated by the "IPv6DualStack" feature gate. ([#91824](https://github.com/kubernetes/kubernetes/pull/91824), [@khenidak](https://github.com/khenidak)) [SIG API Machinery, Apps, CLI, Network, Node, Scheduling and Testing]
- Introduces a metric source for HPAs which allows scaling based on container resource usage. ([#90691](https://github.com/kubernetes/kubernetes/pull/90691), [@arjunrn](https://github.com/arjunrn)) [SIG API Machinery, Apps, Autoscaling and CLI]

- Add a metric for time taken to perform recursive permission change ([#95866](https://github.com/kubernetes/kubernetes/pull/95866), [@JornShen](https://github.com/JornShen)) [SIG Instrumentation and Storage]
- Allow cross compilation of kubernetes on different platforms. ([#94403](https://github.com/kubernetes/kubernetes/pull/94403), [@bnrjee](https://github.com/bnrjee)) [SIG Release]
- Command to start network proxy changes from 'KUBE_ENABLE_EGRESS_VIA_KONNECTIVITY_SERVICE ./cluster/kube-up.sh' to 'KUBE_ENABLE_KONNECTIVITY_SERVICE=true ./hack/kube-up.sh' ([#92669](https://github.com/kubernetes/kubernetes/pull/92669), [@Jefftree](https://github.com/Jefftree)) [SIG Cloud Provider]
- DefaultPodTopologySpread graduated to Beta. The feature gate is enabled by default. ([#95631](https://github.com/kubernetes/kubernetes/pull/95631), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling and Testing]
- Kubernetes E2E test image manifest lists now contain Windows images. ([#77398](https://github.com/kubernetes/kubernetes/pull/77398), [@claudiubelu](https://github.com/claudiubelu)) [SIG Testing and Windows]
- Support for Windows container images (OS Versions: 1809, 1903, 1909, 2004) was added the pause:3.4 image. ([#91452](https://github.com/kubernetes/kubernetes/pull/91452), [@claudiubelu](https://github.com/claudiubelu)) [SIG Node, Release and Windows]

### Documentation

- Fake dynamic client: document that List does not preserve TypeMeta in UnstructuredList ([#95117](https://github.com/kubernetes/kubernetes/pull/95117), [@andrewsykim](https://github.com/andrewsykim)) [SIG API Machinery]

### Bug or Regression

- Alter wording to describe pods using a pvc ([#95635](https://github.com/kubernetes/kubernetes/pull/95635), [@RaunakShah](https://github.com/RaunakShah)) [SIG CLI]
- If we set SelectPolicy MinPolicySelect on scaleUp behavior or scaleDown behavior,Horizontal Pod Autoscaler doesn't automatically scale the number of pods correctly ([#95647](https://github.com/kubernetes/kubernetes/pull/95647), [@JoshuaAndrew](https://github.com/JoshuaAndrew)) [SIG Apps and Autoscaling]
- Ignore apparmor for non-linux operating systems ([#93220](https://github.com/kubernetes/kubernetes/pull/93220), [@wawa0210](https://github.com/wawa0210)) [SIG Node and Windows]
- Ipvs: ensure selected scheduler kernel modules are loaded ([#93040](https://github.com/kubernetes/kubernetes/pull/93040), [@cmluciano](https://github.com/cmluciano)) [SIG Network]
- Kubeadm: add missing "--experimental-patches" flag to "kubeadm init phase control-plane" ([#95786](https://github.com/kubernetes/kubernetes/pull/95786), [@Sh4d1](https://github.com/Sh4d1)) [SIG Cluster Lifecycle]
- Reorganized iptables rules to fix a performance issue ([#95252](https://github.com/kubernetes/kubernetes/pull/95252), [@tssurya](https://github.com/tssurya)) [SIG Network]
- Unhealthy pods covered by PDBs can be successfully evicted if enough healthy pods are available. ([#94381](https://github.com/kubernetes/kubernetes/pull/94381), [@michaelgugino](https://github.com/michaelgugino)) [SIG Apps]
- Update the PIP when it is not in the Succeeded provisioning state during the LB update. ([#95748](https://github.com/kubernetes/kubernetes/pull/95748), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]

## Changelog since v1.20.0-alpha.1

## Changes by Kind

### Deprecation

- Action-required: kubeadm: graduate the "kubeadm alpha certs" command to a parent command "kubeadm certs". The command "kubeadm alpha certs" is deprecated and will be removed in a future release.

- Scheduler alpha metrics binding_duration_seconds and scheduling_algorithm_preemption_evaluation_seconds are deprecated, Both of those metrics are now covered as part of framework_extension_point_duration_seconds, the former as a PostFilter the latter and a Bind plugin. The plan is to remove both in 1.21 ([#95001](https://github.com/kubernetes/kubernetes/pull/95001), [@arghya88](https://github.com/arghya88)) [SIG Instrumentation and Scheduling]

### API Change

- Server Side Apply now treats LabelSelector fields as atomic (meaning the entire selector is managed by a single writer and updated together), since they contain interrelated and inseparable fields that do not merge in intuitive ways. ([#93901](https://github.com/kubernetes/kubernetes/pull/93901), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Storage and Testing]

## Changelog since v1.20.0-alpha.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](https://github.com/kubernetes/kubernetes/pull/92905), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
  - CVE-2020-8559 (Medium): Privilege escalation from compromised node to cluster. See https://github.com/kubernetes/kubernetes/issues/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](https://github.com/kubernetes/kubernetes/pull/92941), [@tallclair](https://github.com/tallclair)) [SIG API Machinery]
 
## 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](https://github.com/kubernetes/kubernetes/pull/93570), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Apps and 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](https://github.com/kubernetes/kubernetes/pull/92881), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: remove the deprecated "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io. This change also removes the parent command "kubeadm alpha kubelet" as there are no more sub-commands under it for the time being. ([#94668](https://github.com/kubernetes/kubernetes/pull/94668), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: remove the deprecated --kubelet-config flag for the command "kubeadm upgrade node" ([#94869](https://github.com/kubernetes/kubernetes/pull/94869), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubelet's deprecated endpoint `metrics/resource/v1alpha1` has been removed, please adopt to `metrics/resource`. ([#94272](https://github.com/kubernetes/kubernetes/pull/94272), [@RainbowMango](https://github.com/RainbowMango)) [SIG Instrumentation and Node]
- The v1alpha1 PodPreset API and admission plugin has been removed with no built-in replacement. Admission webhooks can be used to modify pods on creation. ([#94090](https://github.com/kubernetes/kubernetes/pull/94090), [@deads2k](https://github.com/deads2k)) [SIG API Machinery, Apps, CLI, Cloud Provider, Scalability and Testing]

### API Change

- A new `nofuzz` go build tag now disables gofuzz support. Release binaries enable this. ([#92491](https://github.com/kubernetes/kubernetes/pull/92491), [@BenTheElder](https://github.com/BenTheElder)) [SIG API Machinery]
- 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](https://github.com/kubernetes/kubernetes/pull/92001), [@huffmanca](https://github.com/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](https://github.com/kubernetes/enhancements/blob/master/keps/sig-node/135-seccomp/README.md#version-skew-strategy) for more detailed explanations. ([#91408](https://github.com/kubernetes/kubernetes/pull/91408), [@saschagrunert](https://github.com/saschagrunert)) [SIG Apps, Auth, CLI and Node]
- Adds the ability to disable Accelerator/GPU metrics collected by Kubelet ([#91930](https://github.com/kubernetes/kubernetes/pull/91930), [@RenaudWasTaken](https://github.com/RenaudWasTaken)) [SIG Node]
- Custom Endpoints are now mirrored to EndpointSlices by a new EndpointSliceMirroring controller. ([#91637](https://github.com/kubernetes/kubernetes/pull/91637), [@robscott](https://github.com/robscott)) [SIG API Machinery, Apps, Auth, Cloud Provider, Instrumentation, Network and Testing]
- External facing API podresources is now available under k8s.io/kubelet/pkg/apis/ ([#92632](https://github.com/kubernetes/kubernetes/pull/92632), [@RenaudWasTaken](https://github.com/RenaudWasTaken)) [SIG Node and Testing]
- Fix conversions for custom metrics. ([#94481](https://github.com/kubernetes/kubernetes/pull/94481), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Instrumentation]
- 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 empty; for example, restoring from snapshot is supported. ([#92784](https://github.com/kubernetes/kubernetes/pull/92784), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps, Auth, CLI, Instrumentation, Node, Scheduling, Storage and Testing]
- Kube-controller-manager: volume plugins can be restricted from contacting local and loopback addresses by setting `--volume-host-allow-local-loopback=false`, or from contacting specific CIDR ranges by setting `--volume-host-cidr-denylist` (for example, `--volume-host-cidr-denylist=127.0.0.1/28,feed::/16`) ([#91785](https://github.com/kubernetes/kubernetes/pull/91785), [@mattcary](https://github.com/mattcary)) [SIG API Machinery, Apps, Auth, CLI, Network, Node, 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](https://github.com/kubernetes/kubernetes/pull/93264), [@justaugustus](https://github.com/justaugustus)) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Release, Scalability, Storage and Testing]
- Migrate scheduler, controller-manager and cloud-controller-manager to use LeaseLock ([#94603](https://github.com/kubernetes/kubernetes/pull/94603), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery, Apps, Cloud Provider and Scheduling]
- Modify DNS-1123 error messages to indicate that RFC 1123 is not followed exactly ([#94182](https://github.com/kubernetes/kubernetes/pull/94182), [@mattfenwick](https://github.com/mattfenwick)) [SIG API Machinery, Apps, Auth, Network and Node]
- The ServiceAccountIssuerDiscovery feature gate is now Beta and enabled by default. ([#91921](https://github.com/kubernetes/kubernetes/pull/91921), [@mtaufen](https://github.com/mtaufen)) [SIG Auth]
- The kube-controller-manager managed signers can now have distinct signing certificates and keys.

### Feature

- ACTION REQUIRED : In CoreDNS v1.7.0, [metrics names have been changed](https://github.com/coredns/coredns/blob/master/notes/coredns-1.7.0.md#metric-changes) 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.

      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](https://github.com/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

- 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.
