Changelog since v1.6.10

Other notable changes

  • Update kube-dns to 1.14.5 (#53112, @bowei)
  • Fix panic in ControllerManager on GCE when it has a problem with creating external loadbalancer healthcheck (#52646, @gmarek)
  • When performing a GET then PUT, the kube-apiserver must write the canonical representation of the object to etcd if the current value does not match. That allows external agents to migrate content in etcd from one API version to another, across different storage types, or across varying encryption levels. This fixes a bug introduced in 1.5 where we unintentionally stopped writing the newest data. (#48394, @smarterclayton)
  • StatefulSet will now fill the hostname and subdomain fields if they're empty on existing Pods it owns. This allows it to self-correct the issue where StatefulSet Pod DNS entries disappear after upgrading to v1.7.x (#48327). (#51199, @kow3ns)
  • Make logdump support kubemark and support gke with 'use_custom_instance_list' (#51834, @shyamjvs)
  • Fix credentials providers for docker sandbox image. (#51870, @feiskyer)

Changelog since v1.6.3

Other notable changes

  • Fix kubelet panic during disk eviction introduced in 1.6.3. (#46049, @enisoc)
  • Fix pods failing to start if they specify a file as a volume subPath to mount. (#46046, @enisoc)

v1.6.3

Documentation & Examples

Known Issues for v1.6.3

  • This release introduced a regression when using subPath. If the subPath is a file rather than a directory, Pods may fail to start (#45613).

    Do not upgrade to v1.6.3 if your cluster may run Pods with such subPaths.

WARNING: etcd backup strongly recommended

Before updating to 1.6, you are strongly recommended to back up your etcd data. Please consult the installation procedure you are using (kargo, kops, kube-up, kube-aws, kubeadm etc) for specific advice.

1.6 encourages etcd3, and switching from etcd2 to etcd3 involves a full migration of data between different storage engines. You must stop the API from writing to etcd during an etcd2 -> etcd3 migration. HA installations cannot be migrated at the current time using the official Kubernetes procedure.

1.6 will also default to protobuf encoding if using etcd3. This change is irreversible. To rollback, you must restore from a backup made before the protobuf/etcd3 switch, and any changes since the backup will be lost. As 1.5 does not support protobuf encoding, if you roll back to 1.5 after upgrading to protobuf you will be forced to restore from backup, and you will lose any changes since you converted to protobuf. After conversion to protobuf, you should validate the correct operation of your cluster thoroughly before returning it to normal operation.

Backups are always a good precaution, particularly around upgrades, but this upgrade has multiple known issues where the only remedy is to restore from backup.

Also, please note:

  • using application/vnd.kubernetes.protobuf as the media storage type for 1.6 is default but not required

  • the ability to rollback to etcd2 can be preserved by setting the storage media type flag on kube-apiserver

    --storage-media-type application/json

    to continue to use application/json as the storage media type which can be changed to application/vnd.kubernetes.protobuf at a later time.

Major updates and release themes

  • Kubernetes now supports up to 5,000 nodes via etcd v3, which is enabled by default.
  • Role-based access control (RBAC) has graduated to beta, and defines secure default roles for control plane, node, and controller components.
  • The kubeadm cluster bootstrap tool has graduated to beta. Some highlights:
    • WARNING: A known issue in v1.6.0 causes kubeadm init to hang. Please use v1.6.1, which fixes the issue.
    • All communication is now over TLS
    • Authorization plugins can be installed by kubeadm, including the new default of RBAC
    • The bootstrap token system now allows token management and expiration
  • The kubefed federation bootstrap tool has also graduated to beta.
  • Interaction with container runtimes is now through the CRI interface, enabling easier integration of runtimes with the kubelet. Docker remains the default runtime via Docker-CRI (which moves to beta).
    • WARNING: A known issue in v1.6.0 causes Pod.Spec.HostPid (using the host PID namespace for the pod) to always be false. Please wait for v1.6.2, which will include a fix for this issue.
  • Various scheduling features have graduated to beta:
  • You can now specify (per pod) how long a pod should stay bound to a node, when there is a node problem.
  • Various storage features have graduated to GA:
  • DaemonSets can now be updated by a rolling update.

Action Required

Certificates API

  • Users of the alpha certificates API should delete v1alpha1 CSRs from the API before upgrading and recreate them as v1beta1 CSR after upgrading. (#39772, @mikedanese)

Cluster Autoscaler

  • If you are using (or planning to use) Cluster Autoscaler please wait for Kubernetes 1.6.1. In 1.6.0 Cluster Autoscaler may occasionally increase the size of the cluster a bit more than it is actually needed, when there are unschedulable pods, scale up is required and cloud provider is slow to set up networking for new nodes. Anyway, the cluster should get back to the proper size after 10 min.

Deployment

Federation

  • The --dns-provider argument of 'kubefed init' is now mandatory and does not default to google-clouddns. To initialize a Federation control plane with Google Cloud DNS, use the following invocation: 'kubefed init --dns-provider=google-clouddns' (#42092, @marun)
  • Cluster federation servers have changed the location in etcd where federated services are stored, so existing federated services must be deleted and recreated. Before upgrading, export all federated services from the federation server and delete the services. After upgrading the cluster, recreate the federated services from the exported data. (#37770, @enj)

Internal Storage Layer

  • upgrade to etcd3 prior to upgrading to 1.6 OR explicitly specify --storage-backend=etcd2 --storage-media-type=application/json when starting the apiserver

Node Components

  • Kubelet with the Docker-CRI implementation
    • The Docker-CRI implementation is enabled by default.
    • It is not compatible with containers created by older Kubelets. It is recommended to drain your node before upgrade. If you choose to perform an in-place upgrade, the Kubelet will automatically restart all Kubernetes-managed containers on the node.
    • It is not compatible with CNI plugins that do not conform to the error handling behavior in the spec. The plugins are being updated to resolve this issue (#43488). You can disable CRI explicitly (--enable-cri=false) as a temporary workaround.
      • The standard bridge plugin have been validated to interoperate with the new CRI + CNI code path.
      • If you are using plugins other than bridge, make sure you have updated custom plugins to the latest version that is compatible.
  • CNI plugins now affect node readiness
    • Kubelet will now block node readiness until a CNI configuration file is present in /etc/cni/net.d or a given custom CNI configuration path. This change ensures kubelet does not start pods that require networking before networking is ready. This change may require changes to clients that gate pod creation and/or scheduling on the node condition type Ready status being True for pods that need to run prior to the network being ready.
  • Enhance Kubelet QoS:
    • Pods are placed under a new cgroup hierarchy by default. This feature requires draining and restarting the node as part of upgrades. To opt-out set --cgroups-per-qos=false.
    • If kube-reserved and/or system-reserved are specified, node allocatable will be enforced on all pods by default. To opt-out set --enforce-node-allocatable=””
    • Hard Eviction Thresholds will be subtracted from Capacity while calculating Node Allocatable. This will result in a reduction of schedulable capacity in clusters post upgrade where kubelet hard eviction has been turned on for memory. To opt-out set --experimental-allocatable-ignore-eviction=true.
    • More details on these feature here: https://kubernetes.io/docs/tasks/administer-cluster/reserve-compute-resources/
  • Drop the support for docker 1.9.x. Docker versions 1.10.3, 1.11.2, 1.12.6 have been validated.
  • The following deprecated kubelet flags are removed: --config, --auth-path, --resource-container, --system-container, --reconcile-cidr
  • Remove the temporary fix for pre-1.0 mirror pods. Upgrade directly from pre-1.0 to 1.6 kubelet is not supported.
  • Fluentd was migrated to Daemon Set, which targets nodes with beta.kubernetes.io/fluentd-ds-ready=true label. If you use fluentd in your cluster please make sure that the nodes with version 1.6+ contains this label.

kubectl

  • Running kubectl taint (alpha in 1.5) against a 1.6 server requires upgrading kubectl to version 1.6
  • Running kubectl taint (alpha in 1.5) against a 1.5 server requires a kubectl version of 1.5
  • Running kubectl create secret no longer accepts passing multiple values to a single --from-literal flag using comma separation
    • Update command invocations to pass separate --from-literal flags for each value

RBAC

  • Default ClusterRole and ClusterRoleBinding objects are automatically updated at server start to add missing permissions and subjects (extra permissions and subjects are left in place). To prevent autoupdating a particular role or rolebinding, annotate it with rbac.authorization.kubernetes.io/autoupdate=false. (#41155, @liggitt)
  • v1beta1 RoleBinding/ClusterRoleBinding subjects changed apiVersion to apiGroup to fully-qualify a subject. ServiceAccount subjects default to an apiGroup of "", User and Group subjects default to an apiGroup of "rbac.authorization.k8s.io". (#41184, @liggitt)
  • To create or update an RBAC RoleBinding or ClusterRoleBinding object, a user must: (#39383, @liggitt)
      1. Be authorized to make the create or update API request
      1. Be allowed to bind the referenced role, either by already having all of the permissions contained in the referenced role, or by having the "bind" permission on the referenced role.
  • The --authorization-rbac-super-user flag (alpha in 1.5) is deprecated; the system:masters group has privileged access (#38121, @deads2k)
  • special handling of the user * in RoleBinding and ClusterRoleBinding objects is removed in v1beta1. To match all users, explicitly bind to the group system:authenticated and/or system:unauthenticated. Existing v1alpha1 bindings to the user * are automatically converted to the group system:authenticated. (#38981, @liggitt)

Scheduling

  • Multiple schedulers

    • Modify your PodSpecs that currently use the scheduler.alpha.kubernetes.io/name annotation on Pod, to instead use the schedulerName field in the PodSpec.
    • Modify any custom scheduler(s) you have written so that they read the schedulerName field on Pod instead of the scheduler.alpha.kubernetes.io/name annotation.
    • Note that you can only start using the schedulerName field after you upgrade to 1.6; it is not recognized in 1.5.
  • Node affinity/anti-affinity and pod affinity/anti-affinity

    • You can continue to use the alpha version of this feature (with one caveat -- see below), in which you specify affinity requests using Pod annotations, in 1.6 by including AffinityInAnnotations=true in --feature-gates, such as --feature-gates=FooBar=true,AffinityInAnnotations=true. Otherwise, you must modify your PodSpecs that currently use the scheduler.alpha.kubernetes.io/affinity annotation on Pod, to instead use the affinity field in the PodSpec. Support for the annotation will be removed in a future release, so we encourage you to switch to using the field as soon as possible.
    • Caveat: The alpha version no longer supports, and the beta version does not support, the "empty podAffinityTerm.namespaces list means all namespaces" behavior. In both alpha and beta it now means "same namespace as the pod specifying this affinity rule."
    • Note that you can only start using the affinity field after you upgrade to 1.6; it is not recognized in 1.5.
    • The --failure-domains scheduler command line-argument is not supported in the beta version of the feature.
  • Taints

    • You will need to use kubectl taint to re-create all of your taints after kubectl and the master are upgraded to 1.6. Between the time the master is upgraded to 1.6 and when you do this, your existing taints will have no effect.
    • You can find out what taints you have in place on a node while you are still running Kubernetes 1.5 by doing kubectl describe node <node name>; the Taints section will show the taints you have in place. To see the taints that were created under 1.5 when you are running 1.6, do kubectl get node <node name> -o yaml and look for the "Annotation" section with the annotation key scheduler.alpha.kubernetes.io/taints
    • You can remove the "old" taints (stored internally as annotations) at any time after the upgrade by doing kubectl annotate nodes <node name> scheduler.alpha.kubernetes.io/taints- (note the minus at the end, which means "delete the taint with this key")
    • Note that because any taints you might have created with Kubernetes 1.5 can only affect the scheduling of new pods (the NoExecute taint effect is introduced in 1.6), neither the master upgrade nor your running kubectl taint to re-create the taints will affect pods that are already running.
    • Rescheduler relies on taints, which were changed in a backward incompatible way. Rescheduler 0.3 shipped together with Kubernetes 1.6 understands the new taints and will clean up the old annotations, but Rescheduler 0.2 shipped together with Kubernetes 1.5 doesn't understand the new taints. In order to avoid eviction loop during 1.5->1.6 upgrade you need to either upgrade the master node atomically (for example by using upgrade.sh script for GCE) or ensure that the rescheduler is upgraded first, then the scheduler and then all the other master components.
  • Tolerations

    • After your master is upgraded to 1.6, you will need to update your PodSpecs to set the tolerations field of the PodSpec and remove the scheduler.alpha.kubernetes.io/tolerations annotation on the Pod. (It's not strictly necessary to remove the annotation, as it will have no effect once you upgrade to 1.6.) Between the time the master is upgraded to 1.6 and when you do this, tolerations attached to Pods that are created will have no effect. Pods that are already running will not be affected by the upgrade.
    • You can find the PodSpec tolerations that were created as annotations (if any) in a controller definition by doing kubectl get <controller kind> <controller name> -o yaml and looking for the "Annotation" section with the annotation key scheduler.alpha.kubernetes.io/tolerations (This will work whether you are running Kubernetes 1.5 or 1.6).
    • To update a controller's PodSpec to use the field instead of the annotation, use one of the kubectl commands that do update ("kubectl replace" or "kubectl apply" or "kubectl patch") or just delete the controller entirely and re-create it with a new pod template. Note that you will be able to do these things only after the upgrade.

Service

  • The 'endpoints.beta.kubernetes.io/hostnames-map' annotation is no longer supported. Users can use the 'Endpoints.subsets[].addresses[].hostname' field instead. (#39284, @bowei)

StatefulSet

  • StatefulSet now respects ControllerRef to avoid fighting over Pods. At the time of upgrade, you must not have StatefulSets with selectors that overlap with any other controllers (such as ReplicaSets), or else ownership of Pods may change. (#42080, @enisoc)

Volumes

  • StorageClass pre-installed and set as default on Azure, AWS, GCE, OpenStack, and vSphere.
    • This is something to pay close attention to if you’ve been using Kubernetes for a while, because it changes the default behavior of PersistentVolumeClaim objects on these clouds.
    • Marking a StorageClass as default makes it so that even a PersistentVolumeClaim without a StorageClass specified will trigger dynamic provisioning (instead of binding to an existing pool of PVs).
    • If you depend on the old behavior of volumes binding to existing pool of PersistentVolume objects then modify the StorageClass object and set storageclass.beta.kubernetes.io/is-default-class to false.
  • Flex volume plugin is updated to support attach/detach interfaces. It broke backward compatibility. Please update your drivers and implement the new callouts. (#41804, @chakri-nelluri)

Notable Features

Features for this release were tracked via the use of the kubernetes/features issues repo. Each Feature issue is owned by a Special Interest Group from the kubernetes/community.

Autoscaling

  • [alpha] The Horizontal Pod Autoscaler now supports drawing metrics through the API server aggregator.
  • [alpha] The Horizontal Pod Autoscaler now supports scaling on multiple, custom metrics.
  • Cluster Autoscaler publishes its status to kube-system/cluster-autoscaler-status ConfigMap.
  • Cluster Autoscaler can continue operations while some nodes are broken or unready.
  • Cluster Autoscaler respects Pod Disruption Budgets when removing a node.

DaemonSet

Deployment

  • [beta] Deployments that cannot make progress in rolling out the newest version will now indicate via the API they are blocked (docs)

Federation

  • [beta] kubefed has graduated to beta: supports hosting federation on on-prem clusters, automatically configures kube-dns in joining clusters and allows passing arguments to federation components.

Internal Storage Layer

  • [stable] The internal storage layer for kubernetes cluster state has been updated to use etcd v3 by default. Existing clusters will have to plan for a data migration window. (docs)(kubernetes/features#44)

kubeadm

  • [beta] Introduces an API for clients to request TLS certificates from the API server. See the tutorial.
  • [beta] kubeadm is enhanced and improved with a baseline feature set and command line flags that are now marked as beta. Other parts of kubeadm, including subcommands under kubeadm alpha, are still in alpha. Using it is considered safe, although note that upgrades and HA are not yet supported. Please try it out and give us feedback!
  • [alpha] New Bootstrap Token authentication and management method. Works well with kubeadm. kubeadm now supports managing tokens, including time based expiration, after the cluster is launched. See kubeadm reference docs for details.
  • [alpha] Adds a new cloud-controller-manager binary that may be used for testing the new out-of-core cloudprovider flow.

Node Components

  • [stable] Init containers have graduated to GA and now appear as a field. The beta annotation value will still be respected and overrides the field value.
  • Kubelet Container Runtime Interface (CRI) support
    • [beta] The Docker-CRI implementation is enabled by default in kubelet. You can disable it by --enable-cri=false. See notes on the new implementation for more details.
    • [alpha] Alpha support for other runtimes: cri-o, frakti, rkt.
  • [beta] Node Problem Detector is beta (v0.3.0) now. New features added into node-problem-detector:v0.3.0:
    • Add support for journald.
    • The ability to monitor any system daemon logs. Previously only kernel logs were supported.
    • The ability to be deployed and run as a native daemon.
  • [alpha] Critical Pods: When feature gate "ExperimentalCriticalPodAnnotation" is set to true, the system will guarantee scheduling and admission of pods with the following annotation - scheduler.alpha.kubernetes.io/critical-pod
    • This feature should be used in conjunction with the rescheduler to guarantee resource availability for critical system pods.
  • [alpha] --experimental-nvidia-gpus flag is replaced by Accelerators alpha feature gate along with addition of support for multiple Nvidia GPUs.
    • To use GPUs, pass Accelerators=true as part of --feature-gates flag.
    • More information here.
  • A pod’s Quality of Service Class is now available in its Status.
  • Upgrade cAdvisor library to v0.25.0. Notable changes include,
    • Container filesystem usage tracking disabled for device mapper due to excessive IOPS.
    • Ignore .mount cgroups, fixing disappearing stats.
  • A new field terminationMessagePolicy has been added to containers that allows a user to request FallbackToLogsOnError, which will read from the container's logs to populate the termination message if the user does not write to the termination message log file. The termination message file is now properly readable for end users and has a maximum size (4k bytes) to prevent abuse. Each pod may have up to 12k bytes of termination messages before the contents of each will be truncated.
  • Do not delete pod objects until all its compute resource footprint has been reclaimed.
    • This feature prevents the node and scheduler from oversubscribing resources that are still being used by a pod in the process of being cleaned up.
    • This feature can result in increase of Pod Deletion latency especially if the pod has a large filesystem footprint.

RBAC

  • [beta] RBAC API is promoted to v1beta1 (rbac.authorization.k8s.io/v1beta1), and defines default roles for control plane, node, and controller components.
  • [beta] The Docker-CRI implementation is Beta and is enabled by default in kubelet. You can disable it by --enable-cri=false. See notes on the new implementation for more details.

Scheduling

  • [beta] The multiple schedulers. This feature allows you to run multiple schedulers in parallel, each responsible for different sets of pods. When using multiple schedulers, the scheduler name is now specified in a new-in-1.6 schedulerName field of the PodSpec rather than using the scheduler.alpha.kubernetes.io/name annotation on the Pod. When you upgrade to 1.6, the Kubernetes default scheduler will start using the schedulerName field of the PodSpec and will ignore the annotation.
  • [beta] Node affinity/anti-affinity and [beta] pod affinity/anti-affinity. Node affinity/anti-affinity allow you to specify rules for restricting which node(s) a pod can schedule onto, based on the labels on the node. Pod affinity/anti-affinity allow you to specify rules for spreading and packing pods relative to one another, across arbitrary topologies (node, zone, etc.) These affinity rules are now be specified in a new-in-1.6 affinity field of the PodSpec. Kubernetes 1.6 continues to support the alpha scheduler.alpha.kubernetes.io/affinity annotation on the Pod if you explicitly enable the alpha feature "AffinityInAnnotations", but it will be removed in a future release. When you upgrade to 1.6, if you have not enabled the alpha feature, then the scheduler will use the affinity field in PodSpec and will ignore the annotation. If you have enabled the alpha feature, then the scheduler will use the affinity field in PodSpec if it is present, and otherwise will use the annotation.
  • [beta] Taints and tolerations. This feature allows you to specify rules for "repelling" pods from nodes by default, which enables use cases like dedicated nodes and reserving nodes with special features for pods that need those features. We've also added a NoExecute taint type that evicts already-running pods, and an associated tolerationSeconds field to tolerations to delay the eviction for a specified amount of time. As before, taints are created using kubectl taint (but internally they are now represented as a field taints in the NodeSpec rather than using the scheduler.alpha.kubernetes.io/taints annotation on Node). Tolerations are now specified in a new-in-1.6 tolerations field of the PodSpec rather than using the scheduler.alpha.kubernetes.io/tolerations annotation on the Pod. When you upgrade to 1.6, the scheduler will start using the fields and will ignore the annotations.
  • [alpha] Represent node problems "not ready" and "unreachable" using NoExecute taints. In combination with tolerationSeconds described below, this allows per-pod specification of how long to remain bound to a node that becomes unreachable or not ready, rather than using the default of 5 minutes. You can enable this alpha feature by including TaintBasedEvictions=true in --feature-gates, such as --feature-gates=FooBar=true,TaintBasedEvictions=true. Documentation is here.

Service Catalog

  • [alpha] Adds a new API resource PodPreset and admission controller to enable defining cross-cutting injection of Volumes and Environment into Pods.

Volumes

  • [stable] StorageClass API is promoted to v1 (storage.k8s.io/v1).
  • [stable] Default storage classes are deployed during installation on Azure, AWS, GCE, OpenStack and vSphere.
  • [stable] Added ability to populate environment variables from a configmap or secret.
  • [stable] Support for user-written/run dynamic PV provisioners. The Kubernetes Incubator contains a golang library and examples.
  • [stable] Volume plugin for ScaleIO enabling pods to seamlessly access and use data stored on Dell EMC ScaleIO volumes.
  • [stable] Volume plugin for Portworx added capability to use Portworx as a storage provider for Kubernetes clusters. Portworx pools server capacity and turns servers or cloud instances into converged, highly available compute and storage nodes.
  • [stable] Add support to use NFSv3, NFSv4, and GlusterFS on GCE/GKE GCI image based clusters.
  • [beta] Added support for mount options in persistent volumes.
  • [alpha] All in one volume proposal - a new volume driver capable of projecting secrets, configmaps, and downward API items into the same directory.

Deprecations

  • Remove extensions/v1beta1 Jobs resource, and job/v1beta1 generator. (#38614, @soltysh)
  • federation/deploy/deploy.sh was an interim solution introduced in Kubernetes v1.4 to simplify the federation control plane deployment experience. Now that we have kubefed, we are deprecating deploy.sh scripts. (#38902, @madhusudancs)

Cluster Provisioning Scripts

kubeadm

  • Quite a few flags been renamed or removed. Those options that are removed as flags can still be accessed via the config file. Most notably this includes external etcd settings and the option for setting the cloud provider on the API server. The kubeadm reference documentation is up to date with the new flags.

Other Deprecations

  • Remove cmd/kube-discovery from the tree since it's not necessary anymore (#42070, @luxas)

Changes to API Resources

ABAC

  • ABAC policies using "user":"*" or "group":"*" to match all users or groups will only match authenticated requests. To match unauthenticated requests, ABAC policies must explicitly specify "group":"system:unauthenticated" (#38968, @liggitt)

Admission Control

  • Adds a new API resource PodPreset and admission controller to enable defining cross-cutting injection of Volumes and Environment into Pods. (#41931, @jessfraz)
  • Enable DefaultTolerationSeconds admission controller by default (#41815, @kevin-wangzefeng)
  • ResourceQuota ability to support default limited resources (#36765, @derekwaynecarr)
  • Add defaultTolerationSeconds admission controller (#41414, @kevin-wangzefeng)
  • An automountServiceAccountToken field was added to ServiceAccount and PodSpec objects. If set to false on a pod spec, no service account token is automounted in the pod. If set to false on a service account, no service account token is automounted for that service account unless explicitly overridden in the pod spec. (#37953, @liggitt)
  • Admission control support for versioned configuration files (#39109, @derekwaynecarr)
  • Ability to quota storage by storage class (#34554, @derekwaynecarr)

Authentication

  • The authentication.k8s.io API group was promoted to v1(#41058, @liggitt)

Authorization

  • The authorization.k8s.io API group was promoted to v1 (#40709, @liggitt)
  • The SubjectAccessReview API now passes subresource and resource name information to the authorizer to answer authorization queries. (#40935, @liggitt)

Autoscaling

  • Introduces an new alpha version of the Horizontal Pod Autoscaler including expanded support for specifying metrics. (#36033, @DirectXMan12
  • HorizontalPodAutoscaler is no longer supported in extensions/v1beta1 version. Use autoscaling/v1 instead. (#35782, @piosz)
  • Fixes an HPA-related panic due to division-by-zero. (#39694, @DirectXMan12)

Certificates

  • The CertificateSigningRequest API added the extra field to persist all information about the requesting user. This mirrors the fields in the SubjectAccessReview API used to check authorization. (#41755, @liggitt)
  • Native support for token based bootstrap flow. This includes signing a well known ConfigMap in the kube-public namespace and cleaning out expired tokens. (#36101, @jbeda)

ConfigMap

  • Volumes and environment variables populated from ConfigMap and Secret objects can now tolerate the named source object or specific keys being missing, by adding optional: true to the volume or environment variable source specifications. (#39981, @fraenkel)

CronJob

  • Add configurable limits to CronJob resource to specify how many successful and failed jobs are preserved. (#40932, @peay)

DaemonSet

  • DaemonSet now respects ControllerRef to avoid fighting over Pods. (#42173, @enisoc)
  • Make DaemonSet respect critical pods annotation when scheduling. (#42028, @janetkuo)
  • Implement the update feature for DaemonSet. (#41116, @lukaszo)
  • Make DaemonSets survive taint-based evictions when nodes turn unreachable/notReady. (#41896, @kevin-wangzefeng)

  • DaemonSet ObservedGeneration (#39157, @lukaszo)

Deployment

  • Add ready replicas in Deployments (#37959, @kargakis)
  • Deployments that cannot make progress in rolling out the newest version will now indicate via the API they are blocked
  • Introduce apps/v1beta1.Deployments resource with modified defaults compared to extensions/v1beta1.Deployments. (#39683, @soltysh)
  • Introduce new generator for apps/v1beta1 deployments (#42362, @soltysh)

Node

Pod

  • Init containers have graduated to GA and now appear as a field. The beta annotation value will still be respected and overrides the field value. (#38382, @hodovska)
  • A new field terminationMessagePolicy has been added to containers that allows a user to request FallbackToLogsOnError, which will read from the container's logs to populate the termination message if the user does not write to the termination message log file. The termination message file is now properly readable for end users and has a maximum size (4k bytes) to prevent abuse. Each pod may have up to 12k bytes of termination messages before the contents of each will be truncated. (#39341, @smarterclayton)
  • Fix issue with PodDisruptionBudgets in which minAvailable specified as a percentage did not work with StatefulSet Pods. (#39454, @foxish)
  • Node affinity has moved from annotations to api fields in the pod spec. Node affinity that is defined in the annotations will be ignored. (#37299, @rrati)
  • Moved pod affinity and anti-affinity from annotations to api fields #25319 (#39478, @rrati)
  • Add QoS pod status field (#37968, @sjenning)

  • A user can now be authorized to bind a particular role by having permission to perform the bind verb on the referenced role (#39383, @liggitt)

ReplicaSet

  • ReplicaSet has onwer ref of the Deployment that created it (#35676, @krmayankk)

Secrets

  • Populate environment variables from a secrets. (#39446, @fraenkel)
  • Added a new secret type "bootstrap.kubernetes.io/token" for dynamically creating TLS bootstrapping bearer tokens. (#41281, @ericchiang)

Service

  • Endpoints, that tolerate unready Pods, are now listing Pods in state Terminating as well (#37093, @simonswine)
  • Fix Service Update on LoadBalancerSourceRanges Field (#37720, @freehan)
  • Bug fix. Incoming UDP packets not reach newly deployed services (#32561, @zreigz)
  • Services of type loadbalancer consume both loadbalancer and nodeport quota. (#39364, @zhouhaibing089)

StatefulSet

  • Fix zone placement heuristics so that multiple mounts in a StatefulSet pod are created in the same zone (#40910, @justinsb)
  • Fixes issue #38418 which, under circumstance, could cause StatefulSet to deadlock. (#40838, @kow3ns)
    • Mediates issue #36859. StatefulSet only acts on Pods whose identity matches the StatefulSet, providing a partial mediation for overlapping controllers.

Taints and Tolerations

  • Add a manager to NodeController that is responsible for removing Pods from Nodes tainted with NoExecute Taints. This feature is beta (as the rest of taints) and enabled by default. It's gated by controller-manager enable-taint-manager flag. (#40355, @gmarek)
  • Add an alpha feature that makes NodeController set Taints instead of deleting Pods from not Ready Nodes. (#41133, @gmarek)
  • Make tolerations respect wildcard key (#39914, @kevin-wangzefeng)
  • Forgiveness alpha version api definition (#39469, @kevin-wangzefeng)
  • Rescheduler uses taints in v1beta1 and will remove old ones (in version v1alpha1) right after its start. (#43106, @piosz)

Volumes

  • StorageClassName attribute has been added to PersistentVolume and PersistentVolumeClaim objects and should be used instead of annotation volume.beta.kubernetes.io/storage-class. The beta annotation is still working in this release, however it will be removed in a future release. (#42128, @jsafrane)
  • Parameter keys in a StorageClass parameters map may not use the kubernetes.io or k8s.io namespaces. (#41837, @liggitt)
  • Add storage.k8s.io/v1 API (#40088, @jsafrane)
  • Alpha version of dynamic volume provisioning is removed in this release. Annotation (#40000, @jsafrane)
  • Reduce verbosity of volume reconciler when attaching volumes (#36900, @codablock)
  • We change the default attach_detach_controller sync period to 1 minute to reduce the query frequency through cloud provider to check whether volumes are attached or not. (#41363, @jingxu97)

Changes to Major Components

API Server

  • --anonymous-auth is enabled by default, unless the API server is started with the AlwaysAllow authorizer. (#38706, @deads2k)
  • When using OIDC authentication and specifying --oidc-username-claim=email, an "email_verified":true claim must be returned from the identity provider. (#36087, @ericchiang)
    • --basic-auth-file supports optionally specifying groups in the fourth column of the file (#39651, @liggitt)
  • API server now has two separate limits for read-only and mutating inflight requests. (#36064, @gmarek)
  • Restored normalization of custom --etcd-prefix when --storage-backend is set to etcd3 (#42506, @liggitt)
  • Updating apiserver to return http status code 202 for a delete request when the resource is not immediately deleted because of user requesting cascading deletion using DeleteOptions.OrphanDependents=false. (#41165, @nikhiljindal)
  • Use full package path for definition name in OpenAPI spec (#40124, @mbohlool)
  • Follow redirects for streaming requests (exec/attach/port-forward) in the apiserver by default (alpha -> beta). (#40039, @timstclair)
  • Add 'X-Content-Type-Options: nosniff" to some error messages (#37190, @brendandburns)
  • Fixes bug in resolving client-requested API versions (#38533, @DirectXMan12)
  • Replace glog.Fatals with fmt.Errorfs (#38175, @sttts)
  • Pipe get options to storage (#37693, @wojtek-t)
  • The --long-running-request-regexp flag to kube-apiserver is deprecated and will be removed in a future release. Long-running requests are now detected based on specific verbs (watch, proxy) or subresources (proxy, portforward, log, exec, attach). (#38119, @liggitt)
  • if kube-apiserver is started with --storage-backend=etcd2, the media type application/json is used. (#43122, @liggitt)
  • API fields that previously serialized null arrays as null and empty arrays as [] no longer distinguish between those values and always output [] when serializing to JSON. (#43422, @liggitt)
  • Generate OpenAPI definition for inlined types (#39466, @mbohlool)

  • Fix resync goroutine leak in ListAndWatch (#35672, @tatsuhiro-t)

client-go

Cloud Provider

AWS

  • Recognize eu-west-2 region (#38746, @justinsb)
  • Recognize ca-central-1 region (#38410, @justinsb)
  • Add sequential allocator for device names. (#38818, @jsafrane)

Azure

GCE

  • On GCI by default logrotate is disabled for application containers in favor of rotation mechanism provided by docker logging driver. (#40634, @crassirostris)

GKE

vSphere

  • Reverts to looking up the current VM in vSphere using the machine's UUID, either obtained via sysfs or via the vm-uuid parameter in the cloud configuration file. (#40892, @robdaemon)
  • Fix for detach volume when node is not present/ powered off (#40118, @BaluDontu)

  • Fix panic in vSphere cloud provider (#38423, @BaluDontu)
  • Fix space issue in volumePath with vSphere Cloud Provider (#38338, @BaluDontu)

Federation

kubefed

Other Notable Changes

  • Federated Ingress over GCE no longer requires separate firewall rules to be created for each cluster to circumvent flapping firewall health checks. (#41942, @csbell)
  • Add support for finalizers in federated configmaps (deletes configmaps from underlying clusters). (#40464, @csbell)
  • Add support for DeleteOptions.OrphanDependents for federated services. Setting it to false while deleting a federated service also deletes the corresponding services from all registered clusters. (#36390, @nikhiljindal)
  • Add --controllers flag to federation controller manager for enable/disable federation ingress controller (#36643, @kzwang)
  • Stop deleting services from underlying clusters when federated service is deleted. (#37353, @nikhiljindal)
  • Expose autoscaling apis through federation api server (#38976, @irfanurrehman)
  • Federation: Add batch/jobs API objects to federation-apiserver (#35943, @jianhuiz)
  • Add logging of route53 calls (#39964, @justinsb)

Garbage Collector

  • Added foreground garbage collection: the owner object will not be deleted until all its dependents are deleted by the garbage collector. Please checkout the user doc for details. (#38676, @caesarxuchao)
    • deleteOptions.orphanDependents is going to be deprecated in 1.7. Please use deleteOptions.propagationPolicy instead.

kubeadm

  • A new label and taint is used for marking the master. The label is node-role.kubernetes.io/master="" and the taint has the effect NoSchedule. Tolerate the node-role.kubernetes.io/master="":NoSchedule taint to schedule a workload on the master (a networking DaemonSet for example).
  • The kubelet API is now secured, only cluster admins are allowed to access it.
  • Insecure access to the API Server over localhost:8080 is now disabled.
  • The control plane components now talk securely to each other. The API Server talks securely to the kubelets in the cluster.
  • kubeadm creates RBAC-enabled clusters. This means that some add-ons which worked previously won't work without having their YAML configuration updated. Please see each vendor's own documentation to check that the add-ons you are using will work with Kubernetes 1.6.
  • The kube-discovery Deployment isn't used anymore when creating a kubeadm cluster and shouldn't be used anywhere else either due to its insecure nature.
  • The Certificates API has graduated from alpha to beta. This is a backwards-incompatible change since the alpha support is dropped, and therefore kubeadm v1.5 and v1.6 don't work together (for example kubeadm v1.5 can't join a kubeadm v1.6 cluster).
  • Supporting only etcd3, with 3.0.14 as the minimum version.
  • kubeadm reset will no longer drain nodes automatically. This is because the credentials on nodes do not have permission to perform this operation. We have documented an alternate procedure, driven from the API server/master.
  • Hook up kubeadm against the BootstrapSigner (#41417, @luxas)
  • Rename some flags for beta UI and fixup some logic (#42064, @luxas)
  • Insecure access to the API Server at localhost:8080 will be turned off in v1.6 when using kubeadm (#42066, @luxas)
  • Flag --use-kubernetes-version for kubeadm init renamed to --kubernetes-version (#41820, @kad)
  • Remove the --cloud-provider flag for beta init UX (#41710, @luxas)
  • Fixed an SELinux issue in kubeadm on Docker 1.12+ by moving etcd SELinux options from container to pod. (#40682, @dgoodwin)
  • Add authorization mode to kubeadm (#39846, @andrewrynhard)
  • Refactor the certificate and kubeconfig code in the kubeadm binary into two phases (#39280, @luxas)
  • Added kubeadm commands to manage bootstrap tokens and the duration they are valid for. (#35805, @dgoodwin)

    • Fix kubectl get -f -o so it prints all items in the file (#39038, @ncdc)
    • kubectl describe no longer prints the last-applied-configuration annotation for secrets. (#34664, @ymqytw)
    • Completed pods should not be hidden when requested by name via kubectl get. (#42216, @smarterclayton)
    • Improve formatting of EventSource in kubectl get and kubectl describe (#40073, @matthyx)
  • Attach now supports multiple types (#40365, @shiywang)
  • Create now accepts the label selector flag for filtering objects to create (#40057, @MrHohn)
  • Top now accepts short forms for "node" and "pod" ("no", "po") (#39218, @luksa)
  • Begin paths for internationalization in kubectl (#36802, @brendandburns)

Updates to apply

  • New command apply set-last-applied updates the applied-applied-configuration annotation (#41694, @shiywang)
  • New command apply view-last-applied command for viewing the last configuration file applied (#41146, @shiywang)
  • apply now supports explicitly clearing values by setting them to null (#40630, @liggitt)
  • Warn user when using apply on a resource lacking the LastAppliedConfig annotation (#36672, @ymqytw)
  • PATCH (i.e. apply and edit) now supports merging lists of primitives (#38665, @ymqytw)
  • apply falls back to generic 3-way JSON merge patch for Third Party Resource or unregistered types (#40666, @ymqytw)

Updates to edit

  • edit now supports Third party resources and extension API servers. (#41304, @liggitt)
    • Now to edit a particular API version, provide the fully-qualify the resource, version, and group used to fetch the object (for example, job.v1.batch/myjob)
    • Client-side conversion is no longer done, and the --output-version option is deprecated for kubectl edit.
  • edit works as intended with apply and will not change the annotation
    • No longer updates the last-applied-configuration annotation when --save-config is unspecified or false. (#41924, @ymqytw)
    • Fixes issue that caused apply to revert changes made by edit

Bug fixes

  • Fixed --save-config in create subcommand to save the annotation (#40289, @xilabao)
  • Fixed an issue where 'kubectl get --sort-by=' would return an error if the specified fields in sort were not specified in one or more of the returned objects. (#40541, @fabianofranz)
    • Previously this would cause the command to fail regardless of whether or not the field was present in the object model
    • Now the command will succeed even if the sort-by field is missing from one or more of the objects
  • Fixed issue with kubectl proxy so it will now proxy an empty path - e.g. http://localhost:8001 (#39226, @luksa)
  • Fixed an issue where commas were not accepted in --from-literal flags for the creation of secrets. (#35191, @SamiHiltunen)
    • Passing multiple values separated by a comma in a single --from-literal flag is no longer supported. Please use multiple --from-literal flags to provide multiple values.
  • Fixed a bug where the --server, --token, and --certificate-authority flags were not overriding the related in-cluster configs when provided in a kubectl call inside a cluster. (#39006, @fabianofranz)

Other Notable Changes

  • The api server will publish the extensions/Deployments API as preferred over the apps/Deployment (introduced in 1.6). (#43553, @liggitt)
    • This will ensure certain commands in 1.5 versions of kubectl continue function when run against a 1.6 server. (e.g. kubectl edit deployment)
  • Taint
    • The taint command will not function in a skewed 1.5 / 1.6 environment - client and server versions must match (See Action required section above)
    • Change taints/tolerations to api fields (#38957, @aveshagarwal)
    • Make kubectl taint command respect effect NoExecute (#42120, @kevin-wangzefeng)
  • Allow drain --force to remove pods whose managing resource is deleted. (#41864, @marun)
  • --output-version is ignored for all commands except kubectl convert. This is consistent with the generic nature of kubectl CRUD commands and the previous removal of --api-version. Specific versions can be specified in the resource field: resource.version.group, jobs.v1.batch. (#41576, @deads2k)
  • Allow missing keys in templates by default (#39486, @ncdc)
  • Add error message when trying to use clusterrole with namespace in kubectl (#36424, @xilabao)
  • When deleting an object with --grace-period=0, the client will begin a graceful deletion and wait until the resource is fully deleted. To force deletion, use the --force flag. (#37263, @smarterclayton)

Node Components

  • Kubelet config should ignore file start with dots. (#39196, @resouer)
  • Bump GCI to gci-stable-56-9000-84-2. (#41819, @dchen1107)
  • Bump GCE ContainerVM to container-vm-v20170214 to address CVE-2016-9962. (#41449, @zmerlynn)
  • Kubelet: Remove the PLEG health check from /healthz, Kubelet will now report
  • NodeNotReady on failed PLEG health check. (#41569, @yujuhong)
  • CRI: upgrade protobuf to v3. Protobuf v2 and v3 are not compatible. (#39158, @feiskyer)
  • kubelet exports metrics for cgroup management (#41988, @sjenning)
  • Experimental support to reserve a pod's memory request from being utilized by pods in lower QoS tiers. (#41149, @sjenning)
  • Port forwarding can forward over websockets or SPDY. (#33684, @fraenkel)
  • Flag gate faster evictions based on node memory pressure using kernel memcg notifications - --experimental-kernel-memcg-notification. (#38258, @derekwaynecarr)
  • Nodes can now report two additional address types in their status: InternalDNS and ExternalDNS. The apiserver can use --kubelet-preferred-address-types to give priority to the type of address it uses to reach nodes. (#34259, @liggitt)

Bug fixes

kube-controller-manager

kube-dns

  • Adds support for configurable DNS stub domains and upstream nameservers. The following configuration options have been added to the kube-system:kube-dns ConfigMap:

    "stubDomains": {
      "acme.local": ["1.2.3.4"]
    },

    is a map of domain to list of nameservers for the domain. This is used to inject private DNS domains into the kube-dns namespace. In the above example, any DNS requests for *.acme.local will be served by the nameserver 1.2.3.4.

    "upstreamNameservers": ["8.8.8.8", "8.8.4.4"]

    is a list of upstreamNameservers to use, overriding the configuration specified in /etc/resolv.conf.

  • An empty kube-system:kube-dns ConfigMap will be created for the cluster if one did not already exist.

kube-proxy

  • Remove outdated net.experimental.kubernetes.io/proxy-mode and net.beta.kubernetes.io/proxy-mode annotations from kube-proxy. (#40585, @cblecker)
  • proxy/iptables: don't sync proxy rules if services map didn't change (#38996, @dcbw)
  • Update kube-proxy image to be based off of Debian 8.6 base image. (#39695, @ixdy)
  • Update amd64 kube-proxy base image to debian-iptables-amd64:v5 (#39725, @ixdy)
  • Clean up the kube-proxy container image by removing unnecessary packages and files. (#42090, @timstclair)
  • Better compat with very old iptables (e.g. CentOS 6) (#37594, @thockin)

     },

    is a map of domain to list of nameservers for the domain. This is used to inject private DNS domains into the kube-dns namespace. In the above example, any DNS requests for *.acme.local will be served by the

    nameserver 1.2.3.4.

  • Cleanup fluentd-gcp image: rebase on debian-base, switch to upstream packages, remove fluent-ui & rails (#41998, @timstclair)
  • On GCE, the apiserver audit log (/var/log/kube-apiserver-audit.log) will be sent through fluentd if enabled. It will go to the same place as kube-apiserver.log, but tagged as its own stream. (#41360, @enisoc)
  • If experimentalCriticalPodAnnotation feature gate is set to true, fluentd pods will not be evicted by the kubelet. (#41035, @vishh)

    • "stubDomains": {
    • "acme.local": ["1.2.3.4"]
    • },
    • is a map of domain to list of nameservers for the domain. This is used
    • to inject private DNS domains into the kube-dns namespace. In the above
    • example, any DNS requests for *.acme.local will be served by the
    • nameserver 1.2.3.4.
    • "upstreamNameservers": ["8.8.8.8", "8.8.4.4"]

Changelog since v1.6.0-alpha.2

Other notable changes

  • Fix AWS device allocator to only use valid device names (#41455, @gnufied)
  • [Federation][Kubefed] Bug fix relating kubeconfig path in kubefed init (#41410, @irfanurrehman)
  • The apiserver audit log (/var/log/kube-apiserver-audit.log) will be sent through fluentd if enabled. (#41360, @enisoc)
  • Bump GCE ContainerVM to container-vm-v20170214 to address CVE-2016-9962. (#41449, @zmerlynn)
  • Fixed issues #39202, #41041 and #40941 that caused the iSCSI connections to be prematurely closed when deleting a pod with an iSCSI persistent volume attached and that prevented the use of newly created LUNs on targets with preestablished connections. (#41196, @CristianPop)
  • The kube-apiserver basic audit log can be enabled in GCE by exporting the environment variable ENABLE_APISERVER_BASIC_AUDIT=true before running cluster/kube-up.sh. This will log to /var/log/kube-apiserver-audit.log and use the same logrotate settings as /var/log/kube-apiserver.log. (#41211, @enisoc)
  • On kube-up.sh clusters on GCE, kube-scheduler now contacts the API on the secured port. (#41285, @liggitt)
  • Default RBAC ClusterRole and ClusterRoleBinding objects are automatically updated at server start to add missing permissions and subjects (extra permissions and subjects are left in place). To prevent autoupdating a particular role or rolebinding, annotate it with rbac.authorization.kubernetes.io/autoupdate=false. (#41155, @liggitt)
  • Make EnableCRI default to true (#41378, @yujuhong)
  • kubectl edit now edits objects exactly as they were retrieved from the API. This allows using kubectl edit with third-party resources and extension API servers. Because client-side conversion is no longer done, the --output-version option is deprecated for kubectl edit. To edit using a particular API version, fully-qualify the resource, version, and group used to fetch the object (for example, job.v1.batch/myjob) (#41304, @liggitt)
  • We change the default attach_detach_controller sync period to 1 minute to reduce the query frequency through cloud provider to check whether volumes are attached or not. (#41363, @jingxu97)
  • RBAC v1beta1 RoleBinding/ClusterRoleBinding subjects changed apiVersion to apiGroup to fully-qualify a subject. ServiceAccount subjects default to an apiGroup of "", User and Group subjects default to an apiGroup of "rbac.authorization.k8s.io". (#41184, @liggitt)
  • Add support for finalizers in federated configmaps (deletes configmaps from underlying clusters). (#40464, @csbell)
  • Make DaemonSet controller respect node taints and pod tolerations. (#41172, @janetkuo)
  • Added kubectl create role command (#39852, @xingzhou)
  • If experimentalCriticalPodAnnotation feature gate is set to true, fluentd pods will not be evicted by the kubelet. (#41035, @vishh)

Changelog since v1.5.0

Action Required

  • Promote certificates.k8s.io to beta and enable it by default. Users using the alpha certificates API should delete v1alpha1 CSRs from the API before upgrading and recreate them as v1beta1 CSR after upgrading. (#39772, @mikedanese)
  • Switch default etcd version to 3.0.14. (#36229, @wojtek-t)
    • Switch default storage backend flag in apiserver to etcd3 mode.
  • RBAC's special handling of the user * in RoleBinding and ClusterRoleBinding objects is deprecated and will be removed in v1beta1. To match all users, explicitly bind to the group system:authenticated and/or system:unauthenticated. Existing v1alpha1 bindings to the user * will be automatically converted to the group system:authenticated. (#38981, @liggitt)
  • The 'endpoints.beta.kubernetes.io/hostnames-map' annotation is no longer supported. Users can use the 'Endpoints.subsets[].addresses[].hostname' field instead. (#39284, @bowei)
  • federation/deploy/deploy.sh was an interim solution introduced in Kubernetes v1.4 to simplify the federation control plane deployment experience. Now that we have kubefed, we are deprecating deploy.sh scripts. (#38902, @madhusudancs)
  • Cluster federation servers have changed the location in etcd where federated services are stored, so existing federated services must be deleted and recreated. Before upgrading, export all federated services from the federation server and delete the services. After upgrading the cluster, recreate the federated services from the exported data. (#37770, @enj)
  • etcd2: watching from 0 returns all initial states as ADDED events (#38079, @hongchaodeng)

  • kubectl create now accepts the label selector flag for filtering objects to create (#40057, @MrHohn)
  • A new field terminationMessagePolicy has been added to containers that allows a user to request FallbackToLogsOnError, which will read from the container's logs to populate the termination message if the user does not write to the termination message log file. The termination message file is now properly readable for end users and has a maximum size (4k bytes) to prevent abuse. Each pod may have up to 12k bytes of termination messages before the contents of each will be truncated. (#39341, @smarterclayton)

    • AWS, Google Compute Engine, Google Container Engine, and OpenStack using
    • the default kube-up.sh scripts. This StorageClass is marked as default so that
    • a PersistentVolumeClaim without a StorageClass annotation now results in
    • automatic provisioning of storage (GCE PersistentDisk on Google Cloud, AWS
    • EBS on AWS, and Cinder on OpenStack). In previous versions of Kubernetes
    • a PersistentVolumeClaim without a StorageClass annotation on these cloud
    • platforms would be satisfied by manually-created PersistentVolume objects.
    • Administrators can choose to disable this behavior by deleting the automatically
    • installed StorageClass API object. Alternatively, administrators may choose to
    • keep the automatically installed StorageClass and only disable the defaulting
    • behavior by removing the "is-default-class" annotation from the StorageClass
    • API object.
