([#58185](https://github.com/kubernetes/kubernetes/pull/58185), [@caesarxuchao](https://github.com/caesarxuchao)) * Action required: Before upgrading your Kubernetes clusters, double check if you had configured webhooks for cluster-scoped objects (e.g., nodes, persistentVolume), these webhooks will start to take effect. Delete/modify the configs if that's not desirable. ### Other notable changes * CustomResourceDefinitions: OpenAPI v3 validation schemas containing `$ref`references are no longer permitted (valid references could not be constructed previously because property ids were not permitted either). Before upgrading, ensure CRD definitions do not include those `$ref` fields.

`9961ad142abc7e769bbe962aeb30a014065fae83291a2d65bc2da91f04fbf185` ## 1.9 Release Notes ## WARNING: etcd backup strongly recommended Before updating to 1.9, you are strongly recommended to back up your etcd data. Consult the installation procedure you are using (kargo, kops, kube-up, kube-aws, kubeadm etc) for specific advice. Some upgrade methods might upgrade etcd from 3.0 to 3.1 automatically when you upgrade from Kubernetes 1.8, unless you specify otherwise. Because [etcd does not support downgrading](https://coreos.com/etcd/docs/latest/upgrades/upgrade_3_1.html), you'll need to either remain on etcd 3.1 or restore from a backup if you want to downgrade back to Kubernetes 1.8. ## Introduction to 1.9.0 Kubernetes version 1.9 includes new features and enhancements, as well as fixes to identified issues. The release notes contain a brief overview of the important changes introduced in this release. The content is organized by Special Interest Group ([SIG](https://github.com/kubernetes/community/blob/master/sig-list.md)). For initial installations, see the [Setup topics](https://kubernetes.io/docs/setup/pick-right-solution/) in the Kubernetes documentation. To upgrade to this release from a previous version, first take any actions required [Before Upgrading](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.9.md#before-upgrading). For more information about this release and for the latest documentation, see the [Kubernetes documentation](https://kubernetes.io/docs/home/). ## Major themes Kubernetes is developed by community members whose work is organized into [Special Interest Groups](https://github.com/kubernetes/community/blob/master/sig-list.md), which provide the themes that guide their work. For the 1.9 release, these themes included: ### API Machinery Extensibility. SIG API Machinery added a new class of admission control webhooks (mutating), and brought the admission control webhooks to beta. ### Apps The core workloads API, which is composed of the DaemonSet, Deployment, ReplicaSet, and StatefulSet kinds, has been promoted to GA stability in the apps/v1 group version. As such, the apps/v1beta2 group version is deprecated, and all new code should use the kinds in the apps/v1 group version. ### Auth SIG Auth focused on extension-related authorization improvements. Permissions can now be added to the built-in RBAC admin/edit/view roles using [cluster role aggregation](https://kubernetes.io/docs/admin/authorization/rbac/#aggregated-clusterroles). [Webhook authorizers](https://kubernetes.io/docs/admin/authorization/webhook/) can now deny requests and short-circuit checking subsequent authorizers. Performance and usability of the beta [PodSecurityPolicy](https://kubernetes.io/docs/concepts/policy/pod-security-policy/) feature was also improved. ### AWS In v1.9 SIG AWS has improved stability of EBS support across the board. If a Volume is “stuck” in the attaching state to a node for too long a unschedulable taint will be applied to the node, so a Kubernetes admin can [take manual steps to correct the error](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-attaching-volume.html). Users are encouraged to ensure they are monitoring for the taint, and should consider automatically terminating instances in this state. In addition, support for NVMe disks has been added to Kubernetes, and a service of type LoadBalancer can now be backed with an NLB instead of an ELB (alpha). ### Azure SIG Azure worked on improvements in the cloud provider, including significant work on the Azure Load Balancer implementation. ### Cluster Lifecycle SIG Cluster Lifecycle has been focusing on improving kubeadm in order to bring it to GA in a future release, as well as developing the [Cluster API](https://github.com/kubernetes/kube-deploy/tree/master/cluster-api). For kubeadm, most new features, such as support for CoreDNS, IPv6 and Dynamic Kubelet Configuration, have gone in as alpha features. We expect to graduate these features to beta and beyond in the next release. The initial Cluster API spec and GCE sample implementation were developed from scratch during this cycle, and we look forward to stabilizing them into something production-grade during 2018. ### Instrumentation In v1.9 we focused on improving stability of the components owned by the SIG, including Heapster, Custom Metrics API adapters for Prometheus, and Stackdriver. ### Network In v1.9 SIG Network has implemented alpha support for IPv6, and alpha support for CoreDNS as a drop-in replacement for kube-dns. Additionally, SIG Network has begun the deprecation process for the extensions/v1beta1 NetworkPolicy API in favor of the networking.k8s.io/v1 equivalent. ### Node SIG Node iterated on the ability to support more workloads with better performance and improved reliability. Alpha features were improved around hardware accelerator support, device plugins enablement, and cpu pinning policies to enable us to graduate these features to beta in a future release. In addition, a number of reliability and performance enhancements were made across the node to help operators in production. ### OpenStack In this cycle, SIG OpenStack focused on configuration simplification through smarter defaults and the use of auto-detection wherever feasible (Block Storage API versions, Security Groups) as well as updating API support, including: * Block Storage (Cinder) V3 is now supported. * Load Balancer (Octavia) V2 is now supported, in addition to Neutron LBaaS V2. * Neutron LBaas V1 support has been removed. This work enables Kubernetes to take full advantage of the relevant services as exposed by OpenStack clouds. Refer to the [Cloud Providers](https://kubernetes.io/docs/concepts/cluster-administration/cloud-providers/#openstack) documentation for more information. ### Storage [SIG Storage](https://github.com/kubernetes/community/tree/master/sig-storage) is responsible for storage and volume plugin components. For the 1.9 release, SIG Storage made Kubernetes more pluggable and modular by introducing an alpha implementation of the Container Storage Interface (CSI). CSI will make installing new volume plugins as easy as deploying a pod, and enable third-party storage providers to develop their plugins without the need to add code to the core Kubernetes codebase. The SIG also focused on adding functionality to the Kubernetes volume subsystem, such as alpha support for exposing volumes as block devices inside containers, extending the alpha volume-resizing support to more volume plugins, and topology-aware volume scheduling. ### Windows We are advancing support for Windows Server and Windows Server Containers to beta along with continued feature and functional advancements on both the Kubernetes and Windows platforms. This opens the door for many Windows-specific applications and workloads to run on Kubernetes, significantly expanding the implementation scenarios and the enterprise reach of Kubernetes. ## Before Upgrading Consider the following changes, limitations, and guidelines before you upgrade: ### **API Machinery** * The admission API, which is used when the API server calls admission control webhooks, is moved from `admission.v1alpha1` to `admission.v1beta1`. You must **delete any existing webhooks before you upgrade** your cluster, and update them to use the latest API. This change is not backward compatible. * The admission webhook configurations API, part of the admissionregistration API, is now at v1beta1. Delete any existing webhook configurations before you upgrade, and update your configuration files to use the latest API. For this and the previous change, see also [the documentation](https://kubernetes.io/docs/admin/extensible-admission-controllers/#external-admission-webhooks). * A new `ValidatingAdmissionWebhook` is added (replacing `GenericAdmissionWebhook`) and is available in the generic API server. You must update your API server configuration file to pass the webhook to the `--admission-control` flag. ([#55988](https://github.com/kubernetes/kubernetes/pull/55988),[ @caesarxuchao](https://github.com/caesarxuchao)) ([#54513](https://github.com/kubernetes/kubernetes/pull/54513),[ @deads2k](https://github.com/deads2k)) * The deprecated options `--portal-net` and `--service-node-ports` for the API server are removed. ([#52547](https://github.com/kubernetes/kubernetes/pull/52547),[ @xiangpengzhao](https://github.com/xiangpengzhao)) ### **Auth** * PodSecurityPolicy: A compatibility issue with the allowPrivilegeEscalation field that caused policies to start denying pods they previously allowed was fixed. If you defined PodSecurityPolicy objects using a 1.8.0 client or server and set allowPrivilegeEscalation to false, these objects must be reapplied after you upgrade. ([#53443](https://github.com/kubernetes/kubernetes/pull/53443),[ @liggitt](https://github.com/liggitt)) * KMS: Alpha integration with GCP KMS was removed in favor of a future out-of-process extension point. Discontinue use of the GCP KMS integration and ensure [data has been decrypted](https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/#decrypting-all-data) (or reencrypted with a different provider) before upgrading ([#54759](https://github.com/kubernetes/kubernetes/pull/54759),[ @sakshamsharma](https://github.com/sakshamsharma)) ### **CLI** * Swagger 1.2 validation is removed for kubectl. The options `--use-openapi` and `--schema-cache-dir` are also removed because they are no longer needed. ([#53232](https://github.com/kubernetes/kubernetes/pull/53232),[ @apelisse](https://github.com/apelisse)) ### **Cluster Lifecycle** * You must either specify the `--discovery-token-ca-cert-hash` flag to `kubeadm join`, or opt out of the CA pinning feature using `--discovery-token-unsafe-skip-ca-verification`. * The default `auto-detect` behavior of the kubelet's `--cloud-provider` flag is removed. * You can manually set `--cloud-provider=auto-detect`, but be aware that this behavior will be removed completely in a future version. * Best practice for version 1.9 and future versions is to explicitly set a cloud-provider. See [the documentation](https://kubernetes.io/docs/getting-started-guides/scratch/#cloud-providers) * The kubeadm `--skip-preflight-checks` flag is now deprecated and will be removed in a future release. * If you are using the cloud provider API to determine the external host address of the apiserver, set `--external-hostname` explicitly instead. The cloud provider detection has been deprecated and will be removed in the future ([#54516](https://github.com/kubernetes/kubernetes/pull/54516),[ @dims](https://github.com/dims)) ### **Multicluster** * Development of Kubernetes Federation has moved to [github.com/kubernetes/federation](https://github.com/kubernetes/federation). This move out of tree also means that Federation will begin releasing separately from Kubernetes. Impact: * Federation-specific behavior will no longer be included in kubectl * kubefed will no longer be released as part of Kubernetes * The Federation servers will no longer be included in the hyperkube binary and image. ([#53816](https://github.com/kubernetes/kubernetes/pull/53816),[ @marun](https://github.com/marun)) ### **Node** * The kubelet `--network-plugin-dir` flag is removed. This flag was deprecated in version 1.7, and is replaced with `--cni-bin-dir`. ([#53564](https://github.com/kubernetes/kubernetes/pull/53564),[ @supereagle](https://github.com/supereagle)) * kubelet's `--cloud-provider` flag no longer defaults to "auto-detect". If you want cloud-provider support in kubelet, you must set a specific cloud-provider explicitly.

The content is populated from the [v1.9.x known issues and FAQ accumulator] [#57159](https://github.com/kubernetes/kubernetes/issues/57159). * If you are adding Windows Server Virtual Machines as nodes to your Kubernetes environment, there is a compatibility issue with certain virtualization products. Specifically the Windows version of the kubelet.exe calls `GetPhysicallyInstalledSystemMemory` to get the physical memory installed on Windows machines and reports it as part of node metrics to heapster. This API call fails for VMware and VirtualBox virtualization environments. This issue is not present in bare metal Windows deployments, in Hyper-V, or on some of the popular public cloud providers. * If you run `kubectl get po` while the API server in unreachable, a misleading error is returned: `the server doesn't have a resource type "po"`. To work around this issue, specify the full resource name in the command instead of the abbreviation: `kubectl get pods`. This issue will be fixed in a future release. For more information, see [#57198](https://github.com/kubernetes/kubernetes/issues/57198). * Mutating and validating webhook configurations are continuously polled by the API server (once per second). This issue will be fixed in a future release. For more information, see [#56357](https://github.com/kubernetes/kubernetes/issues/56357). * Audit logging is slow because writes to the log are performed synchronously with requests to the log. This issue will be fixed in a future release. For more information, see [#53006](https://github.com/kubernetes/kubernetes/issues/53006). * Custom Resource Definitions (CRDs) are not properly deleted under certain conditions. This issue will be fixed in a future release. For more information, see [#56348](https://github.com/kubernetes/kubernetes/issues/56348). * API server times out after performing a rolling update of the etcd cluster. This issue will be fixed in a future release. For more information, see [#47131](https://github.com/kubernetes/kubernetes/issues/47131) * If a namespaced resource is owned by a cluster scoped resource, and the namespaced dependent is processed before the cluster scoped owner has ever been observed by the garbage collector, the dependent will be erroneously deleted.

`f086659462b6dcdd78abdf13bed339dd67c1111931bae962044aa4ae2396921d` ## Changelog since v1.9.0-alpha.3 ### Action Required * Adds alpha support for volume scheduling, which allows the scheduler to make PersistentVolume binding decisions while respecting the Pod's scheduling requirements. Dynamic provisioning is not supported with this feature yet. ([#55039](https://github.com/kubernetes/kubernetes/pull/55039), [@msau42](https://github.com/msau42)) * Action required for existing users of the LocalPersistentVolumes alpha feature: * The VolumeScheduling feature gate also has to be enabled on kube-scheduler and kube-controller-manager. * The NoVolumeNodeConflict predicate has been removed. For non-default schedulers, update your scheduler policy. * The CheckVolumeBinding predicate has to be enabled in non-default schedulers. * Action required: ([#56004](https://github.com/kubernetes/kubernetes/pull/56004), [@caesarxuchao](https://github.com/caesarxuchao)) * The `admission/v1alpha1` API has graduated to `v1beta1`. Please delete your existing webhooks before upgrading the cluster, and update your admission webhooks to use the latest API, because the API has backwards incompatible changes. * The webhook registration related part of the `admissionregistration` API has graduated to `v1beta1`. Please delete your existing configurations before upgrading the cluster, and update your configuration file to use the latest API. * [action required] kubeadm join: Error out if CA pinning isn't used or opted out of ([#55468](https://github.com/kubernetes/kubernetes/pull/55468), [@yuexiao-wang](https://github.com/yuexiao-wang)) * kubeadm now requires the user to specify either the `--discovery-token-ca-cert-hash` flag or the `--discovery-token-unsafe-skip-ca-verification` flag. ### Other notable changes * A new priority function `ResourceLimitsPriorityMap` (disabled by default and behind alpha feature gate and not part of the scheduler's default priority functions list) that assigns a lowest possible score of 1 to a node that satisfies one or both of input pod's cpu and memory limits, mainly to break ties between nodes with same scores.

Clients using older endpoints will be unaffected. This change is only at the REST API level and is independent of the default behavior of particular clients (e.g. this does not affect the default for the kubectl `--cascade` flag).

allowed privileged pods to start forbidding them, due to an incorrect default value for `allowPrivilegeEscalation`. PodSecurityPolicy objects defined using a 1.8.0 client or server that intended to set `allowPrivilegeEscalation` to `false` must be reapplied after upgrading to 1.8.1.

`543110cc69b57471f3824d96cbd16b003ac2cddaa19ca4bdefced0af61fd24f2` ## Changelog since v1.8.0-alpha.3 ### Action Required * New GCE or GKE clusters created with `cluster/kube-up.sh` will not enable the legacy ABAC authorizer by default. If you would like to enable the legacy ABAC authorizer, export ENABLE_LEGACY_ABAC=true before running `cluster/kube-up.sh`. ([#51367](https://github.com/kubernetes/kubernetes/pull/51367), [@cjcullen](https://github.com/cjcullen)) * The OwnerReferencesPermissionEnforcement admission plugin now requires `update` permission on the `finalizers` subresource of the referenced owner in order to set `blockOwnerDeletion` on an owner reference. ([#49133](https://github.com/kubernetes/kubernetes/pull/49133), [@deads2k](https://github.com/deads2k)) * The deprecated alpha and beta initContainer annotations are no longer supported. Init containers must be specified using the initContainers field in the pod spec. ([#51816](https://github.com/kubernetes/kubernetes/pull/51816), [@liggitt](https://github.com/liggitt)) * Action required: validation rule on metadata.initializers.pending[x].name is tightened. The initializer name needs to contain at least three segments separated by dots. If you create objects with pending initializers, (i.e., not relying on apiserver adding pending initializers according to initializerconfiguration), you need to update the initializer name in existing objects and in configuration files to comply to the new validation rule. ([#51283](https://github.com/kubernetes/kubernetes/pull/51283), [@caesarxuchao](https://github.com/caesarxuchao)) * Audit policy supports matching subresources and resource names, but the top level resource no longer matches the subresouce. For example "pods" no longer matches requests to the logs subresource of pods. Use "pods/logs" to match subresources. ([#48836](https://github.com/kubernetes/kubernetes/pull/48836), [@ericchiang](https://github.com/ericchiang)) * Protobuf serialization does not distinguish between `[]` and `null`. ([#45294](https://github.com/kubernetes/kubernetes/pull/45294), [@liggitt](https://github.com/liggitt)) * API fields previously capable of storing and returning either `[]` and `null` via JSON API requests (for example, the Endpoints `subsets` field) can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6+). JSON API clients should tolerate `null` values for such fields, and treat `null` and `[]` as equivalent in meaning unless specifically documented otherwise for a particular field. ### Other notable changes * PersistentVolumeLabel admission controller is now deprecated. ([#52618](https://github.com/kubernetes/kubernetes/pull/52618), [@dims](https://github.com/dims)) * Mark the LBaaS v1 of OpenStack cloud provider deprecated. ([#52821](https://github.com/kubernetes/kubernetes/pull/52821), [@FengyunPan](https://github.com/FengyunPan)) * NONE ([#52819](https://github.com/kubernetes/kubernetes/pull/52819), [@verult](https://github.com/verult)) * Mark image as deliberately optional in v1 Container struct. Many objects in the Kubernetes API inherit the container struct and only Pods require the field to be set. ([#48406](https://github.com/kubernetes/kubernetes/pull/48406), [@gyliu513](https://github.com/gyliu513)) * [fluentd-gcp addon] Update Stackdriver plugin to version 0.6.7 ([#52565](https://github.com/kubernetes/kubernetes/pull/52565), [@crassirostris](https://github.com/crassirostris)) * Remove duplicate proto errors in kubelet.

([#52541](https://github.com/kubernetes/kubernetes/pull/52541), [@crassirostris](https://github.com/crassirostris)) * The autoscaling/v2beta1 API group is now enabled by default. ([#52549](https://github.com/kubernetes/kubernetes/pull/52549), [@DirectXMan12](https://github.com/DirectXMan12)) * Add CLUSTER_SIGNING_DURATION environment variable to cluster ([#52497](https://github.com/kubernetes/kubernetes/pull/52497), [@jcbsmpsn](https://github.com/jcbsmpsn)) * configuration scripts to allow configuration of signing duration of * certificates issued via the Certificate Signing Request API. * Introduce policy to allow the HPA to consume the metrics.k8s.io and custom.metrics.k8s.io API groups. ([#52572](https://github.com/kubernetes/kubernetes/pull/52572), [@DirectXMan12](https://github.com/DirectXMan12)) * kubelet to master communication when doing node status updates now has a timeout to prevent indefinite hangs ([#52176](https://github.com/kubernetes/kubernetes/pull/52176), [@liggitt](https://github.com/liggitt)) * Introduced Metrics Server in version v0.2.0. For more details see https://github.com/kubernetes-incubator/metrics-server/releases/tag/v0.2.0.

A new "scope" label is added to all apiserver_request_* values that is either 'cluster', 'resource', or 'namespace' depending on which level the query is performed at. ([#52237](https://github.com/kubernetes/kubernetes/pull/52237), [@smarterclayton](https://github.com/smarterclayton)) * Fixed the webhook admission plugin so that it works even if the apiserver and the nodes are in two networks (e.g., in GKE). ([#50476](https://github.com/kubernetes/kubernetes/pull/50476), [@caesarxuchao](https://github.com/caesarxuchao)) * Fixed the webhook admission plugin so that webhook author could use the DNS name of the service as the CommonName when generating the server cert for the webhook. * Action required: * Anyone who generated server cert for admission webhooks need to regenerate the cert.
