Kubernetes 1.13 Release Notes

Security Content

CVE-2018-1002105, a critical security issue in the Kubernetes API Server, is resolved in v1.13.0 (and in v1.10.11, v1.11.5, and v1.12.3). We recommend all clusters running previous versions update to one of these releases immediately. See issue #71411 for details.

Urgent Upgrade Notes

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

Before upgrading to Kubernetes 1.13, you must keep the following in mind:

kube-apiserver
- The deprecated etcd2 storage backend has been removed. Before upgrading a kube-apiserver using --storage-backend=etcd2, etcd v2 data must be migrated to the v3 storage backend, and kube-apiserver invocations changed to use --storage-backend=etcd3. Please consult the installation procedure used to set up etcd for specific migration instructions. Backups prior to upgrade are always a good practice, but since the etcd2 to etcd3 migration is not reversible, an etcd backup prior to migration is essential.
- The deprecated --etcd-quorum-read flag has been removed. Quorum reads are now always enabled when fetching data from etcd. Remove the --etcd-quorum-read flag from kube-apiserver invocations before upgrading.
kube-controller-manager
- The deprecated --insecure-experimental-approve-all-kubelet-csrs-for-group flag has been removed.
kubelet
- The deprecated --google-json-key flag has been removed. Remove the --google-json-key flag from kubelet invocations before upgrading. (#69354, @yujuhong)
- DaemonSet pods now make use of scheduling features that require kubelets to be at 1.11 or above. Ensure all kubelets in the cluster are at 1.11 or above before upgrading kube-controller-manager to 1.13.
- The schema for the alpha CSINodeInfo CRD has been split into spec and status fields, and new fields status.available and status.volumePluginMechanism added. Clusters using the previous alpha schema must delete and recreate the CRD using the new schema. (#70515, @davidz627)
kube-scheduler dropped support for configuration files with apiVersion componentconfig/v1alpha1. Ensure kube-scheduler is configured using command-line flags or a configuration file with apiVersion kubescheduler.config.k8s.io/v1alpha1 before upgrading to 1.13.
kubectl
- The deprecated command run-container has been removed. Invocations should use kubectl run instead (#70728, @Pingan2017)
client-go releases will no longer have bootstrap (k8s.io/client-go/tools/bootstrap) related code. Any reference to it will break. Please redirect all references to k8s.io/bootstrap instead. (#67356, @yliaog)
Kubernetes cannot distinguish between GCE Zonal PDs and Regional PDs with the same name. To workaround this issue, precreate PDs with unique names. PDs that are dynamically provisioned do not encounter this issue. (#70716, @msau42)

Known Issues

If kubelet plugin registration for a driver fails, kubelet will not retry. The driver must delete and recreate the driver registration socket in order to force kubelet to attempt registration again. Restarting only the driver container may not be sufficient to trigger recreation of the socket, instead a pod restart may be required. (#71487)
In some cases, a Flex volume resize may leave a PVC with erroneous Resizing condition even after volume has been successfully expanded. Users may choose to delete the condition, but it is not required. (#71470)
The CSI driver-registrar external sidecar container v1.0.0-rc2 is known to take up to 1 minute to start in some cases. We expect this issue to be resolved in a future release of the sidecar container. For verification, please see the release notes of future releases of the external sidecar container. (#76)
When using IPV6-only, be sure to use proxy-mode=iptables as proxy-mode=ipvs is known to not work. (#68437)

Deprecations

kube-apiserver
- The --service-account-api-audiences flag is deprecated in favor of --api-audiences. The old flag is accepted with a warning but will be removed in a future release. (#70105, @mikedanese)
- The --experimental-encryption-provider-config flag is deprecated in favor of --encryption-provider-config. The old flag is accepted with a warning but will be removed in 1.14. (#71206, @stlaz)
- As part of graduating the etcd encryption feature to beta, the configuration file referenced by --encryption-provider-config now uses kind: EncryptionConfiguration and apiVersion: apiserver.config.k8s.io/v1. Support for kind: EncryptionConfig and apiVersion: v1 is deprecated and will be removed in a future release. (#67383, @stlaz)
- The --deserialization-cache-size flag is deprecated, and will be removed in a future release. The flag is inactive since the etcd2 storage backend was removed. (#69842, @liggitt)
- The Node authorization mode no longer allows kubelets to delete their Node API objects (prior to 1.11, in rare circumstances related to cloudprovider node ID changes, kubelets would attempt to delete/recreate their Node object at startup) (#71021, @liggitt)
- The built-in system:csi-external-provisioner and system:csi-external-attacher cluster roles are deprecated and will not be auto-created in a future release. CSI deployments should provide their own RBAC role definitions with required permissions. (#69868, @pohly)
- The built-in system:aws-cloud-provider cluster role is deprecated and will not be auto-created in a future release. Deployments using the AWS cloud provider should grant required permissions to the aws-cloud-provider service account in the kube-system namespace as part of deployment. (#66635, @wgliang)
kubelet
- Use of the beta plugin registration directory {kubelet_root_dir}/plugins/ for registration of external drivers via the kubelet plugin registration protocol is deprecated in favor of {kubelet_root_dir}/plugins_registry/. Support for the old directory is planned to be removed in v1.15. Device plugin and CSI storage drivers should switch to the new directory prior to v1.15. Only CSI storage drivers that support 0.x versions of the CSI API are allowed in the old directory. (#70494 by @RenaudWasTaken and #71314 by @saad-ali)
- With the release of the CSI 1.0 API, support for CSI drivers using 0.3 and older releases of the CSI API is deprecated, and is planned to be removed in Kubernetes v1.15. CSI drivers should be updated to support the CSI 1.0 API, and deployed in the new kubelet plugin registration directory ({kubelet_root_dir}/plugins_registry/) once all nodes in the cluster are at 1.13 or higher (#71020 and #71314, both by @saad-ali)
- Use of the --node-labels flag to set labels under the kubernetes.io/ and k8s.io/ prefix will be subject to restriction by the NodeRestriction admission plugin in future releases. See admission plugin documentation for allowed labels. (#68267, @liggitt)
kube-scheduler
- The alpha critical pod annotation (scheduler.alpha.kubernetes.io/critical-pod) is deprecated. Pod priority should be used instead to mark pods as critical. (#70298, @bsalamat)
The following features are now GA, and the associated feature gates are deprecated and will be removed in a future release:
- CSIPersistentVolume
- GCERegionalPersistentDisk
- KubeletPluginsWatcher
- VolumeScheduling
kubeadm
- The DynamicKubeletConfig feature gate is deprecated. The functionality is still accessible by using the kubeadm alpha kubelet enable-dynamic command.
- The command kubeadm config print-defaults is deprecated in favor of kubeadm config print init-defaults and kubeadm config print join-defaults (#69617, @rosti)
- support for the v1alpha3 configuration file format is deprecated and will be removed in 1.14. Use kubeadm config migrate to migrate v1alpha3 configuration files to v1beta1, which provides improvements in image repository management, addons configuration, and other areas. The documentation for v1beta1 can be found here: https://godoc.org/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta1
The node.status.volumes.attached.devicePath field is deprecated for CSI volumes and will not be set in future releases (#71095, @msau42)
kubectl
- The kubectl convert command is deprecated and will be removed in a future release (#70820, @seans3)
Support for passing unknown provider names to the E2E test binaries is deprecated and will be removed in a future release. Use --provider=skeleton (no ssh access) or --provider=local (local cluster with ssh) instead. (#70141, @pohly)

Major Themes

SIG API Machinery

For the 1.13 release, SIG API Machinery is happy to announce that the dry-run functionality is now beta.

SIG Auth

With this release we’ve made several important enhancements to core SIG Auth areas. In the authorization category, we’ve further reduced Kubelet privileges by restricting node self-updates of labels to a whitelisted selection and by disallowing kubelets from deleting their Node API object. In authentication, we added alpha-level support for automounting improved service account tokens through projected volumes. We also enabled audience validation in TokenReview for the new tokens for improved scoping. Under audit logging, the new alpha-level “dynamic audit configuration” adds support for dynamically registering webhooks to receive a stream of audit events. Finally, we’ve enhanced secrets protection by graduating etcd encryption out of experimental.

SIG AWS

In v1.13 we worked on tighter integrations of Kubernetes API objects with AWS services. These include three out-of-tree alpha feature releases:

1) Alpha for AWS ALB (Application Load Balancer) integration to Kubernetes Ingress resources. 2) Alpha for CSI specification 0.3 integration to AWS EBS (Elastic Block Store) 3) Alpha for the cloudprovider-aws cloud controller manager binary. Additionally we added aws-k8s-tester, deployer interface for kubetest, to the test-infra repository. This plugin allowed us to integrate Prow to the 3 subprojects defined above in order to provide CI signal for all 3 features. The CI signal is visible here under SIG-AWS.

For detailed release notes on the three alpha features from SIG AWS, please refer to the following Changelogs:

SIG Azure

For 1.13 SIG Azure was focused on adding additional Azure Disk support for Ultra SSD, Standard SSD, and Premium Azure Files. Azure Availability Zones and cross resource group nodes were also moved from Alpha to Beta in 1.13.

SIG Big Data

During the 1.13 release cycle, SIG Big Data has been focused on community engagements relating to 3rd-party project integrations with Kubernetes. There have been no impacts on the 1.13 release.

SIG CLI

Over the course of 1.13 release SIG CLI mostly focused on stabilizing the items we’ve been working on over the past releases such as server-side printing and its support in kubectl, as well as finishing kubectl diff which is based on server-side dry-run feature. We’ve continued separating kubectl code to prepare for extraction out of main repository. Finally, thanks to the awesome support and feedback from community we’ve managed to promote the new plugin mechanism to Beta.

SIG Cloud Provider

For v1.13, SIG Cloud Provider has been focused on stabilizing the common APIs and interfaces consumed by cloud providers today. This involved auditing the cloud provider APIs for anything that should be deprecated as well as adding changes where necessary. In addition, SIG Cloud Provider has begun exploratory work around having a “cloud provider” e2e test suite which can be used to test common cloud provider functionalities with resources such as nodes and load balancers.

We are also continuing our long running effort to extract all the existing cloud providers that live in k8s.io/kubernetes into their own respective repos. Along with this migration, we are slowly transitioning users to use the cloud-controller-manager for any cloud provider features instead of the kube-controller-manager.

SIG Cluster Lifecycle

For 1.13 SIG Cluster Lifecycle is pleased to announce the long awaited promotion of kubeadm to stable GA, and the promotion of kubeadm’s configuration API to v1beta1. In this release the SIG again focused on further improving the user experience on cluster creation and also fixing a number of bugs and other assorted improvements.

Some notable changes in kubeadm since Kubernetes 1.12:

kubeadm’s configuration API is now v1beta1. The new configuration format provides improvements in - image repository management, addons configuration, and other areas. We encourage v1alpha3 users to migrate to this configuration API using kubeadm config migrate, as v1alpha3 will be removed in 1.14. The documentation for v1beta1 can be found here: https://godoc.org/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta1
kubeadm has graduated kubeadm alpha phase commands to kubeadm init phase. This means that the phases of creating a control-plane node are now tightly integrated as part of the init command. Alpha features, not yet ready for GA are still kept under kubeadm alpha and we appreciate feedback on them.
kubeadm init and kubeadm init phase now have a --image-repository flag, improving support for environments with limited access to official kubernetes repository.
The DynamicKubeletConfig and SelfHosting functionality was moved outside of kubeadm init and feature gates and is now exposed under kubeadm alpha.
Kubeadm init phase certs now support the --csr-only option, simplifying custom CA creation.
kubeadm join --experimental-control-plane now automatically adds a new etcd member for local etcd mode, further simplifying required tasks for HA clusters setup.
Improvements were made to kubeadm reset related to cleaning etcd and notifying the user about the state of iptables.
kubeadm commands now print warnings if input YAML documents contain unknown or duplicate fields.
kubeadm now properly recognizes Docker 18.09.0 and newer, but still treats 18.06 as the default supported version.
kubeadm now automatically sets the --pod-infra-container-image flag when starting the kubelet.

SIG IBM Cloud

The IBM Cloud SIG was focused on defining its charter and working towards moving its cloud provider code to an external repository with a goal to have this work done by the end of Kubernetes 1.14 release cycle. In the SIG meetings, we also made sure to share updates on the latest Kubernetes developments in the IBM Cloud like the availability of Kubernetes v1.12.2 in the IBM Cloud Kubernetes Service (IKS). The SIG updates were provided in the Kubernetes community weekly call and at the KubeCon China 2018.

SIG Multicluster

Moving Federation v2 from Alpha towards Beta has been the focus of our effort over the past quarter. To this end we engaged with end users, and successfully enlisted additional contributors from companies including IBM, Amadeus, Cisco and others. Federation v2 provides a suite of decoupled API’s and re-usable components for building multi-cluster control planes. We plan to start releasing Beta components in late 2018. In addition, more minor updates were made to our cluster-registry and multi-cluster ingress sub-projects.

SIG Network

For 1.13, the areas of focus were in IPv6, DNS improvements and some smaller items: CoreDNS is now the default cluster DNS passing all of the scale/resource usage tests Node-local DNS cache feature is available in Alpha. This feature deploys a lightweight DNS caching Daemonset that avoids the conntrack and converts queries from UDP to more reliable TCP. PodReady++ feature now has kubectl CLI support.

Progress was made towards finalizing the IPv6 dual stack support KEP and support for topological routing of services.

SIG Node

SIG Node focused on stability and performance improvements in the 1.13 release. A new alpha feature is introduced to improve the mechanism that nodes heartbeat back to the control plane. The NodeLease feature results in the node using a Lease resource in the kube-node-lease namespace that is renewed periodically. The NodeStatus that was used previously to heartbeat back to the control plane is only updated when it changes. This reduces load on the control plane for large clusters. The Kubelet plugin registration mechanism, which enables automatic discovery of external plugins (including CSI and device plugins) has been promoted to stable in this release (introduced as alpha in 1.11 and promoted to beta in 1.12).

SIG Openstack

The major theme for the SIG OpenStack release is the work-in-progress for removing the in-tree provider. This work, being done in conjunction with SIG Cloud Provider, is focusing on moving internal APIs that the OpenStack (and other providers) depends upon to staging to guarantee API stability. This work also included abstracting the in-tree Cinder API and refactoring code to the external Cinder provider to remove additional Cinder volume provider code.

Additional work was also done to implement an OpenStack driver for the Cluster API effort lead by SIG Cluster Lifecycle. For the external Cloud-Provider-OpenStack code, the SIG largely focused on bug fixes and updates to match K8s 1.13 development.

SIG Scalability

SIG Scalability has mostly focused on stability and deflaking our tests, investing into framework for writing scalability tests (ClusterLoader v2) with a goal to migrate all tests to it by the end of 2018 and on the work towards extending definition of Kubernetes scalability by providing more/better user-friendly SLIs/SLOs.

SIG Scheduling

SIG Scheduling has mostly focused on stability in 1.13 and has postponed some of the major features to the next versions. There are still two notable changes: 1. TaintBasedEviction is moved to Beta and will be enabled by default. With this feature enabled, condition taints are automatically added to the nodes and pods can add tolerations for them if needed. 2. Pod critical annotation is deprecated. Pods should use pod priority instead of the annotation.

It is worth noting again that kube-scheduler will use apiVersion kubescheduler.config.k8s.io/v1alpha1 instead of componentconfig/v1alpha1 in its configuration files in 1.13.

SIG Service Catalog

The Service Plan Defaults feature is still under active development. We continue to improve the UX for the svcat CLI, specifically filling in gaps for the new Namespaced Service Broker feature.

SIG Storage

Over the last year, SIG Storage has been focused on adding support for the Container Storage Interface (CSI) to Kubernetes. The specification recently moved to 1.0, and on the heels of this achievement, Kubernetes v1.13 moves CSI support for PersistentVolumes to GA.

With CSI the Kubernetes volume layer becomes truly extensible, allowing third party storage developers to write drivers making their storage systems available in Kubernetes without having to touch the core code.

CSI was first introduction as alpha in Kubernetes v1.9 and moved to beta in Kubernetes v1.10.

You can find a list of sample and production drivers in the CSI Documentation.

SIG Storage also moves support for Block Volumes to beta (introduced as alpha in v1.9) and support for Topology Aware Volume Scheduling to stable (introduced as alpha in v1.9 and promoted to beta in 1.10).

SIG UI

The migration to the newest version of Angular is still under active development as it is most important thing on the roadmap at the moment. We are getting closer to to the new release. We continue fixing bugs and adding other improvements.

SIG VMWare

Major focus for SIG VMware for this release is the work on moving internal APIs that the vSphere provider depends upon to staging to guarantee API stability. This work is being done in conjunction with SIG Cloud Provider and includes the creation of a brand new vsphere-csi plugin to replace the current volume functionalities in-tree.

Additional work was also done to implement a vSphere provider for the Cluster API effort lead by SIG Cluster Lifecycle. For the out-of-tree vSphere cloud provider, the SIG largely focused on bug fixes and updates to match K8s 1.13 development.

SIG Windows

SIG Windows focused on improving reliability for Windows and Kubernetes support

New Features

Added secure port 10259 to the kube-scheduler (enabled by default) and deprecate old insecure port 10251. Without further flags self-signed certs are created on startup in memory. (#69663, @sttts)

Release Notes From SIGs

SIG API Machinery

The OwnerReferencesPermissionEnforcement admission plugin now checks authorization for the correct scope (namespaced or cluster-scoped) of the owner resource type. Previously, it always checked permissions at the same scope as the child resource. (#70389, @caesarxuchao)
OpenAPI spec now correctly marks delete request’s body parameter as optional (#70032, @iamneha)
The rules for incrementing metadata.generation of custom resources changed: (#69059, @caesarxuchao)
- If the custom resource participates the spec/status convention, the metadata.generation of the CR increments when there is any change, except for the changes to the metadata or the changes to the status.
- If the custom resource does not participate the spec/status convention, the metadata.generation of the CR increments when there is any change to the CR, except for changes to the metadata.
- A custom resource is considered to participate the spec/status convention if and only if the “CustomResourceSubresources” feature gate is turned on and the CRD has .spec.subresources.status={}.
Fixed patch/update operations on multi-version custom resources (#70087, @liggitt)
Reduced memory utilization of admission webhook metrics by removing resource related labels. (#69895, @jpbetz)

Changelog since v1.13.0-alpha.3

Action Required

ACTION REQUIRED: The Node.Status.Volumes.Attached.DevicePath fields is deprecated for CSI volumes and will be unset in a future release (#71095, @msau42)

Other notable changes

Raw block volume support is promoted to beta, and enabled by default. This is accessible via the volumeDevices container field in pod specs, and the volumeMode field in persistent volume and persistent volume claims definitions. (#71167, @msau42)
Fix a scheduler panic due to internal cache inconsistency (#71063, @Huang-Wei)
Fix a potential bug that scheduler preempts unnecessary pods. (#70898, @Huang-Wei)
The API server encryption configuration file format has graduated to stable and moved to apiVersion: apiserver.config.k8s.io/v1 and kind: EncryptionConfiguration. (#67383, @stlaz)
kubelet now supports log-file option to write logs directly to a specific file (#70917, @dims)
kubeadm now supports the --image-repository flag for customizing what registry to pull images from (#71135, @luxas)
timeouts set in ListOptions for clients will also be respected locally (#70998, @deads2k)
IPVS proxier now set net/ipv4/vs/conn_reuse_mode to 0 by default, which will highly improve IPVS proxier performance. (#71114, @Lion-Wei)
StatefulSet is supported in kubectl autoscale command (#71103, @Pingan2017)
Report kube-scheduler unhealthy if leader election is deadlocked. (#71085, @bsalamat)
apiserver: fixes handling and logging of panics in REST handlers (#71076, @liggitt)
kubelets are no longer allowed to delete their own Node API object. Prior to 1.11, in rare circumstances related to cloudprovider node ID changes, kubelets would attempt to delete/recreate their Node object at startup. Kubelets older than 1.11 are not supported running against a v1.13+ API server. If an unsupported legacy kubelet encounters this situation, a cluster admin can remove the Node object: (#71021, @liggitt) * kubectl delete node/<nodeName>
- or grant self-deletion permission explicitly:
  - kubectl create clusterrole self-deleting-nodes --verb=delete --resource=nodes
  - kubectl create clusterrolebinding self-deleting-nodes --clusterrole=self-deleting-nodes --group=system:nodes
Kubernetes v1.13 moves support for Container Storage Interface to GA. As part of this move Kubernetes now supports CSI v1.0.0 and drops support for CSI 0.3 and older releases. Older CSI drivers must be updated to CSI 1.0 in order to work with Kubernetes 1.13+. (#71020, @saad-ali)
Remove deprecated kubectl command aliases ‘run-container’ (#70728, @Pingan2017)
kubeadm: enable strict unmarshaling of YAML configuration files and show warnings for unknown and duplicate fields. (#70901, @neolit123)
For kube-up and derived configurations, CoreDNS will honor master taints, for consistency with kube-dns behavior. (#70868, @justinsb)
CoreDNS is now version 1.2.6 (#70799, @rajansandeep)
kubeadm: Use advertise-client-urls instead of listen-client-urls as and etcd-servers options for apiserver. (#69827, @tomkukral)
Add option to create CSRs instead of certificates for kubeadm init phase certs and kubeadm alpha certs renew (#70809, @liztio)
Add a kubelet socket which serves an grpc service containing the devices used by containers on the node. (#70508, @dashpole)
kube-apiserver: the NodeRestriction admission plugin now prevents kubelets from modifying Node labels prefixed with node-restriction.kubernetes.io/. The node-restriction.kubernetes.io/ label prefix is reserved for cluster administrators to use for labeling Node objects to target workloads to nodes in a way that kubelets cannot modify or spoof. (#68267, @liggitt)
- kubelet: it is now deprecated to use the --node-labels flag to set kubernetes.io/ and k8s.io/-prefixed labels other than the following labels:
  - kubernetes.io/hostname
  - kubernetes.io/instance-type
  - kubernetes.io/os
  - kubernetes.io/arch
  - beta.kubernetes.io/instance-type
  - beta.kubernetes.io/os
  - beta.kubernetes.io/arch
  - failure-domain.kubernetes.io/zone
  - failure-domain.kubernetes.io/region
  - failure-domain.beta.kubernetes.io/zone
  - failure-domain.beta.kubernetes.io/region
  - [*.]kubelet.kubernetes.io/*
  - [*.]node.kubernetes.io/*
- Setting other kubernetes.io/- and k8s.io/-prefixed labels using the --node-labels flag will produce a warning in v1.13, and be disallowed in v1.15. Setting labels that are not prefixed with kubernetes.io/ or k8s.io/ is still permitted.

add Ready column and improve human-readable output of Deployments and StatefulSets (#70466, @Pingan2017)
Kubeadm now respects the custom image registry configuration across joins and upgrades. Kubeadm passes the custom registry to the kubelet for a custom pause container. (#70603, @chuckha)
kubeadm: deprecate the DynamicKubeletConfig feature gate. The functionality is still accessible by using the kubeadm alpha kubelet enable-dynamic command. (#70849, @yagonobre)

CSI drivers now have access to mountOptions defined on the storage class when attaching volumes. (#67898, @bswartz)
The kubectl plugin list command will now display discovered plugin paths in the same order as they are found in a user’s PATH variable. (#70443, @juanvallejo)
Handle Windows named pipes in host mounts. (#69484, @ddebroy)
kubeadm: Multiple API server endpoints support upon join is removed as it is now redundant. (#69812, @rosti)
OpenAPI spec marks delete request’s body parameter as optional (#70032, @iamneha)
kube-controller-manager and cloud-controller-manager now hold generated serving certificates in-memory unless a writeable location is specified with –cert-dir (#69884, @liggitt)
Scheduler only activates unschedulable pods if node’s scheduling related properties change. (#70366, @mlmhl)
–api-audiences now defaults to the –service-account-issuer if the issuer is provided but the API audience is not. (#70308, @mikedanese)
Refactor scheduler_test.go to use a fake k8s client. (#70290, @tossmilestone)
kubectl rollout undo now returns errors when attempting to rollback a deployment to a non-existent revision (#70039, @liggitt)
- kubectl rollout undo no longer uses the deprecated extensions/v1beta1 rollback API, which means that Events are no longer emitted when rolling back a deployment
- The builtin system:csi-external-provisioner and system:csi-external-attacher cluster roles (#69868, @pohly)
- are deprecated and will not be updated for deployments of CSI sidecar container versions >= 0.4.
- Deployments with the current CSI sidecar containers have to provide their own RBAC
- definitions. The reason is that the rules depend on how the sidecar containers are used,
- which is defined by the deployment.
Use debian-base instead of busybox as base image for server images (#70245, @ixdy)
add support for projected volume in describe function (#70158, @WanLinghao)
Speedup process lookup in /proc (#66367, @cpuguy83)
Kubeadm reset now clean up custom etcd data path (#70003, @yagonobre)
We changed when the metadata.generation of a custom resource (CR) increments. (#69059, @caesarxuchao)
- If the CR participates the spec/status convention, the metadata.generation of the CR increments when there is any change, except for the changes to the metadata or the changes to the status.
- If the CR does not participate the spec/status convention, the metadata.generation of the CR increments when there is any change to the CR, except for changes to the metadata.
- A CR is considered to participate the spec/status convention if and only if the “CustomResourceSubresources” feature gate is turned on and the CRD has .spec.subresources.status={}.
Improve Azure instance metadata handling by adding caches. (#70353, @feiskyer)
adding cn-northwest-1 for AWS China Ningxia region (#70155, @pahud)
“kubectl get” no longer exits before printing all of its results if an error is found (#70311, @juanvallejo)
kubeadm now automatically creates a new stacked etcd member when joining a new control plane node (does not applies to external etcd) (#69486, @fabriziopandini)
Critical pod annotation is deprecated. Pod priority should be used instead to mark pods as critical. (#70298, @bsalamat)
Display the usage of ephemeral-storage when using kubectl describe node (#70268, @Pingan2017)
Added functionality to enable br_netfilter and ip_forward for debian packages to improve kubeadm support for CRI runtime besides Docker. (#70152, @ashwanikhemani)
Add regions ap-northeast-3 and eu-west-3 to the list of well known AWS regions. (#70252, @nckturner)
Remove kube-controller-manager flag ‘–insecure-experimental-approve-all-kubelet-csrs-for-group’(deprecated in v1.7) (#69209, @Pingan2017)
GCE/GKE load balancer health check default interval changes from 2 seconds to 8 seconds, unhealthyThreshold to 3. (#70099, @grayluck)
- Health check parameters are configurable to be bigger than default values.
The kubectl wait command must handle when a watch returns an error vs closing by printing out the error and retrying the watch. (#69389, @smarterclayton)
Updates to use debian-iptables v11.0, debian-hyperkube-base 0.12.0, and kube-addon-manager:v8.9. (#70209, @ixdy)
Fixed patch/update operations on multi-version custom resources (#70087, @liggitt)
When --rotate-server-certificates is enabled, kubelet will no longer request a new certificate on startup if the current certificate on disk is satisfactory. (#69991, @agunnerson-ibm)
- Support for passing unknown provider names to the E2E test binaries is going to be deprecated. Use --provider=skeleton (no ssh access) or --provider=local (local cluster with ssh) instead. (#70141, @pohly)
