A complete changelog for the release notes is now hosted in a customizable format at relnotes.k8s.io. Check it out and please give us your feedback!
We’re pleased to announce the delivery of Kubernetes 1.16, our third release of 2019! Kubernetes 1.16 consists of 31 enhancements: 8 enhancements moving to stable, 8 enhancements in beta, and 15 enhancements in alpha.
The main themes of this release are:
- Custom resources: CRDs are in widespread use as a way to extend Kubernetes to persist and serve new resource types, and have been available in beta since the 1.7 release. The 1.16 release marks the graduation of CRDs to general availability (GA).
- Admission webhooks: Admission webhooks are in widespread use as a Kubernetes extensibility mechanism and have been available in beta since the 1.9 release. The 1.16 release marks the graduation of admission webhooks to general availability (GA).
- Overhauled metrics: Kubernetes has previously made extensive use of a global metrics registry to register metrics to be exposed. By implementing a metrics registry, metrics are registered in more transparent means. Previously, Kubernetes metrics have been excluded from any kind of stability requirements.
- Volume Extension: There are quite a few enhancements in this release that pertain to volumes and volume modifications. Volume resizing support in CSI specs is moving to beta which allows for any CSI spec volume plugin to be resizable.
- Topology Manager, a new Kubelet component, aims to co-ordinate resource assignment decisions to provide optimized resource allocations.
- IPv4/IPv6 dual-stack enables the allocation of both IPv4 and IPv6 addresses to Pods and Services.
- API Server Network Proxy going alpha in 1.16.
- Extensions for Cloud Controller Manager Migration.
- Continued deprecation of extensions/v1beta1, apps/v1beta1, and apps/v1beta2 APIs; these extensions will be retired in 1.16!
- The etcd and KMS plugin health checks are not exposed in the new
livez
andreadyz
endpoints. This will be fixed in 1.16.1. - Systems running
iptables
1.8.0 or newer should start it in legacy mode. Please note that this affects all versions of Kubernetes and not only v1.16.0. For more detailed information about the issue and how to apply a workaround, please refer to the official documentation - Generating informers for packages in directories containing dots in their name is broken. This will be fixed in v1.16.1. (#82860)
- kube-scheduler won't be able to report scheduling Events if
events.k8s.io/v1beta1
API is disabled. We are targeting the fix for v1.16.2 (#83203) - The etcd client library vendored in v1.16 (github.com/coreos/etcd/clientv3) has a bug where IPv6 IP addresses get incorrectly trimmed to the first occurance of the
:
character. This affects all users of the client library including the kube-apiserver and kubeadm. We are targeting the fix for this bug in v1.16.3. (#83550)
- Container images tar files for
amd64
will now contain the architecture in the RepoTags manifest.json section. If you are using docker manifests there are not visible changes. (#80266, @javier-b-perez) - kubeadm now deletes the bootstrap-kubelet.conf file after TLS bootstrap User relying on bootstrap-kubelet.conf should switch to kubelet.conf that contains node credentials (#80676, @fabriziopandini)
- Node labels
beta.kubernetes.io/metadata-proxy-ready
,beta.kubernetes.io/metadata-proxy-ready
andbeta.kubernetes.io/kube-proxy-ds-ready
are no longer added on new nodes.- ip-mask-agent addon starts to use the label
node.kubernetes.io/masq-agent-ds-ready
instead ofbeta.kubernetes.io/masq-agent-ds-ready
as its node selector. - kube-proxy addon starts to use the label
node.kubernetes.io/kube-proxy-ds-ready
instead ofbeta.kubernetes.io/kube-proxy-ds-ready
as its node selector. - metadata-proxy addon starts to use the label
cloud.google.com/metadata-proxy-ready
instead ofbeta.kubernetes.io/metadata-proxy-ready
as its node selector.
- ip-mask-agent addon starts to use the label
- When PodInfoOnMount is enabled for a CSI driver, the new csi.storage.k8s.io/ephemeral parameter in the volume context allows a driver's NodePublishVolume implementation to determine on a case-by-case basis whether the volume is ephemeral or a normal persistent volume (#79983, @pohly)
- Add CSI Migration Shim for VerifyVolumesAreAttached and BulkVolumeVerify (#80443, @davidz627)
- Promotes VolumePVCDataSource (Cloning) feature to beta for 1.16 release (#81792, @j-griffith)
- Integrated volume limits for in-tree and CSI volumes into one scheduler predicate. (#77595, @bertinatto)
-

- Graduating Windows GMSA support from alpha to beta (#82110, @wk8)
- Introduce a new admission controller for RuntimeClass. Initially, RuntimeClass will be used to apply the pod overhead associated with a given RuntimeClass to the Pod
spec
if a corresponding RuntimeClassName is specified. PodOverhead is an alpha feature as of Kubernetes 1.16. (#78484, @egernst) - Introduction of the pod overhead feature to the scheduler. This functionality is alpha-level as of Kubernetes v1.16, and is only honored by servers that enable the PodOverhead feature.gate. (#78319, @egernst)
- Ephemeral containers have been added in alpha. These temporary containers can be added to running pods for purposes such as debugging, similar to how
kubectl exec
runs a process in an existing container. Also likekubectl exec
, no resources are reserved for ephemeral containers and they are not restarted when they exit. Note that container namespace targeting is not yet implemented, so process namespace sharing must be enabled to view process from other containers in the pod. (#59484, @verb) - Pod spread constraints have been added in alpha. You can use these constraints to control how Pods are spread across the cluster among failure-domains. (#77327, #77760, #77828, #79062, #80011, #81068, @Huang-Wei)

--all-namespaces
flag is now honored bykubectl wait
(#81468, @ashutoshgngwr) kubectl get -w
now takes an--output-watch-events
flag to indicate the event type (ADDED, MODIFIED, DELETED) (#72416, @liggitt)- Adds Endpoint Slice support for kubectl when discovery API group is enabled. (#81795, @robscott)
- Add
--shutdown-delay-duration
to kube-apiserver in order to delay a graceful shutdown./healthz
will keep returning success during this time and requests are normally served, but/readyz
will return failure immediately. This delay can be used to allow the SDN to update iptables on all nodes and stop sending traffic. (#74416, @sttts) Kubeadm now seamlessly migrates the CoreDNS Configuration when upgrading CoreDNS. (#78033, @rajansandeep) - Add Endpoint Slice Controller for managing new EndpointSlice resource, disabled by default. (#81048, @robscott)
- Adds
\livez
for liveness health checking for kube-apiserver. Using the parameter--maximum-startup-sequence-duration
will allow the liveness endpoint to defer boot-sequence failures for the specified duration period. (#81969, @logicalhan) - Adds EndpointSlice integration to kube-proxy, can be enabled with EndpointSlice feature gate. (#81430, @robscott)

- Volume expansion is enabled in the default GCE storageclass (#78672, @msau42)
- kubeadm ClusterConfiguration now supports featureGates: IPv6DualStack: true (#80145, @Arvinderpal)
- In order to enable dual-stack support within kubeadm and kubernetes components, as part of the init config file, the user should set feature-gate
IPv6DualStack=true
in the ClusterConfiguration. Additionally, for each worker node, the user should set the feature-gate for kubelet using eithernodeRegistration.kubeletExtraArgs
orKUBELET_EXTRA_ARGS
. (#80531, @Arvinderpal) - Add possibility to configure controller manager to use IPv6 dual stack:
use
--cluster-cidr="<cidr1>,<cidr2>"
. Notes: - Add scheduling support for RuntimeClasses. RuntimeClasses can now specify nodeSelector constraints & tolerations, which are merged into the PodSpec for pods using that RuntimeClass. (#80825, @tallclair)
- When specifying
--(kube|system)-reserved-cgroup
, with--cgroup-driver=systemd
, it is now possible to use the fully qualified cgroupfs name (i.e./test-cgroup.slice
). (#78793, @mattjmcnaughton) - Adds support for vSphere volumes on Windows (#80911, @gab-satchi)

- Fix a bug in apiserver that could cause a valid update request to be rejected with a precondition check failure. (#82303, @roycaihw)
- Webhook client credentials configured with
--admission-control-config-file
must include non-default ports in the configured hostnames. For example, a webhook configured to speak to port 8443 on servicemysvc
in namespacemyns
would specify client credentials in a stanza withname: mysvc.myns.svc:8443
. See https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/#authenticate-apiservers for more details. (#82252, @liggitt) - Ensure the KUBE-MARK-DROP chain in kube-proxy mode=ipvs. The chain is ensured for both ipv4 and ipv6 in dual-stack operation. (#82214, @uablrek)
kubectl cp
no longer supports copying symbolic links from containers; to support this use case, seekubectl exec --help

- Node-Problem-Detector v0.7.1 is used for addon daemonset. (#82140, @wangzhen127)
- aggregated discovery requests can now timeout. Aggregated apiserver must complete discovery calls within five seconds. Other requests can take longer. (#82146, @deads2k)

-
- Make kubectl get --ignore-not-found continue processing when encountering error. (#82120, @soltysh)
- Dual stack services (Phase II of IPv6DualStack feature) are enabled via the IPVS proxier. iptables proxier does not support dualstack yet. Dualstack iptables proxier is WIP and should catchup soon. (#82091, @khenidak)
- to enable, kube-proxy must be have the following flags:
- --proxy-mode=ipvs
- --cluster-cidrs=,
- The apiserver now uses http/1.1 to communicate with admission webhooks, opening multiple connections to satisfy concurrent requests, and allowing spreading requests across multiple backing pods. (#82090, @liggitt)
- Added support to specify a global-access annotation for gce ILB. (#81549, @prameshj)
- Added new startupProbe, related to KEP kubernetes/enhancements#950. (#77807, @matthyx)
- Adds \livez for liveness health checking for kube-apiserver. Using the parameter
--maximum-startup-sequence-duration
will allow the liveness endpoint to defer boot-sequence failures for the specified duration period. (#81969, @logicalhan) - Server-side apply is now Beta. (#81956, @apelisse)
- The
rejected
label inapiserver_admission_webhook_admission_duration_seconds
metrics now properly indicates if a request was rejected. Add a new counter metricsapiserver_admission_webhook_rejection_count
with details about the causing for a webhook rejection. (#81399, @roycaihw) - Add
container_state
label torunning_container_count

- Service account tokens now include the JWT Key ID field in their header. (#78502, @ahmedtd)
- Adds EndpointSlice integration to kube-proxy, can be enabled with EndpointSlice feature gate. (#81430, @robscott)
- Azure supports IPv6 only on ELB not ILB. The cloud provider will return an error if the service is internal and is IPv6. (#80485, @khenidak)
- Notes on LB name:
- to ensure backword and forward compat:
-
- SingleStack -v4 (pre v1.16) => BackendPool name == clusterName
-
- SingleStack -v6 => BackendPool name == clusterName (all cluster bootstrap uses this name)
- DualStack:
- => IPv4 BackendPool name == clusterName
- => IPv6 BackendPool name == -IPv6
- This result into:
-
- clusters moving from IPv4 to duakstack will require no changes
-
- clusters moving from IPv6 (while not seen in the wild, we can not rule out their existence) to dualstack will require deleting backend pools (the reconciler will take care of creating correct backendpools)
- Promotes VolumePVCDataSource (Cloning) feature to beta for 1.16 release (#81792, @j-griffith)
- Remove kubectl log, use kubectl logs instead (#78098, @soltysh)

- Kube-controller-manager and cloud-controller-manager metrics are now marked as with the ALPHA stability level. (#81624, @logicalhan)
- Adds Endpoint Slice Controller for managing new EndpointSlice resource, disabled by default. (#81048, @robscott)

- to run: (#79386, @khenidak)
- Master: convert service CIDR to list
--service-cluster-ip-range=<CIDR>,<CIDR>
and make sureIPv6DualStack
feature flag is turned on. The flag is validated and used as the following: -
--service-cluster-ip-range[0]
is consider primary service range, and will be used for any service withService.Spec.IPFamily = nil
or any service in the at the time of turning on the feature flag.
-
- A cluster can be dualstack (i.e. Pods and nodes carry dualstack IPs) but does not need to support ingress on dualstack. In this case the cluster can perform egress using
PodIPs
(according to family and binding selection in user code) but will ingress will only be performed against the pod primary IP. This can be configured by supplying single entry to--service-cluster-ip-range
flag.
- A cluster can be dualstack (i.e. Pods and nodes carry dualstack IPs) but does not need to support ingress on dualstack. In this case the cluster can perform egress using
-
- Maximum of two entries is allowed in
--service-cluster-ip-range
and they are validated to be dual stackedi.e. --service-cluster-ip-range=<v4>,<v6> or --service-cluster-ip-range=<v6>,<v4>
- Maximum of two entries is allowed in

- Max 20 bit for range (min network bits
<v6>/108
or /12)
- Max 20 bit for range (min network bits
- kube-controller-manager: convert service CIDR to list
--service-cluster-ip-range=<CIDR>,<CIDR>
and make sureIPv6DualStack
feature flag is turned on. The flag is validated as above. -
- to use:
- A new service spec field
Service.Spec.IPFamily
has been added. The default of this field is family of (first service cidr in --service-cluster-ip-range flag). The value is defaulted as described above once the feature gate is turned on. Here are the possible values for this field: -
- IPv4: api-server will assign an IP from a
service-cluster-ip-range
that isipv4
(either the primary or the secondary, according to how they were configured).
- IPv4: api-server will assign an IP from a
-
- IPv6: api-server will assign an IP from a
service-cluster-ip-range
that isipv6
(either the primary or the secondary, according to how they were configured).
- IPv6: api-server will assign an IP from a
- Notes (v1.16):
-
- IPVS is the only proxy supported (as of v1.16 ) by Dualstack.
-
- Dualstack is mutually exclusive with
EndpointSlice
feature. They can not be turned on together.metaproxy
is yet to implement EndpointSlice handling.
- Dualstack is mutually exclusive with
- Master: convert service CIDR to list
- to run: (#79386, @khenidak)
- Kubelet metrics for /metrics and /metrics/probes are now marked as with the ALPHA stability level. (#81534, @logicalhan)
- Added metrics 'authentication_attempts' that can be used to understand the attempts of authentication. (#81509, @RainbowMango)
- Fix in kube-proxy for SCTP nodeport service which only works for node's InternalIP, but doesn't work for other IPs present in the node when ipvs is enabled. (#81477, @paulsubrata55)
- The
CustomResourceValidation
,CustomResourceSubresources
,CustomResourceWebhookConversion
andCustomResourcePublishOpenAPI
features are now GA, and the associated feature gates deprecated and will be removed in v1.18. (#81965, @roycaihw) - Node-Problem-Detector v0.7.1 is used on GCI. (#80726, @wangzhen127)
- kubeadm: prevent overriding of certain kubelet security configuration parameters if the user wished to modify them (#81903, @jfbai)
- Introduce
node.kubernetes.io/exclude-balancer
andnode.kubernetes.io/exclude-disruption
labels in alpha to prevent cluster deployers from being dependent on the optionalnode-role
labels which not all clusters may provide. (#80238, @smarterclayton) - Scheduler metrics are now marked as with the ALPHA stability level. (#81576, @logicalhan)
- cache-control headers are now set appropriately. Only openapi is cacheable if etags match. (#81946, @deads2k)
- Added E2E tests validating WindowsOptions.RunAsUserName. (#79539, @bclau)
- Kube-apiserver metrics are now marked as with the ALPHA stability level. (#81531, @logicalhan)
- Move CSI volume expansion to beta. (#81467, @bertinatto)
- Support Kubelet plugin watcher on Windows nodes. (#81397, @ddebroy)
- Updates the requestedToCapacityRatioArguments to add resources parameter that allows the users to specify the resource name along with weights for each resource to score nodes based on the request to capacity ratio. (#77688, @sudeshsh)
- Finalizer Protection for Service LoadBalancers is now in Beta (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted. (#81691, @MrHohn)
- Adds support for vSphere volumes on Windows (#80911, @gab-satchi)
- Log when kube-apiserver regenerates the OpenAPI spec and why. OpenAPI spec generation is a very CPU-heavy process that is sensitive to continuous updates of CRDs and APIServices. (#81786, @sttts)
- Added metrics aggregator_openapi_v2_regeneration_count, aggregator_openapi_v2_regeneration_gauge and apiextension_openapi_v2_regeneration_count metrics counting the triggering APIService and CRDs and the reason (add, update, delete).
- Fix an issue with toleration merging & whitelist checking in the PodTolerationRestriction admission controller. (#81732, @tallclair)
- Add a helper function to decode scheduler plugin args. (#80696, @hex108)
- Add metadata.generation=1 to old CustomResources. (#82005, @sttts)
- kubeadm no longer performs IPVS checks as part of its preflight checks (#81791, @yastij)
- The RemainingItemCount feature is now beta. (#81682, @caesarxuchao)
- remainingItemCount is the number of subsequent items in the list which are not included in this list response. If the list request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. If the list is complete (either because it is not chunking or because this is the last chunk), then there are no more remaining items and this field will be left unset and omitted during serialization. Servers older than v1.15 do not set this field. The intended use of the remainingItemCount is estimating the size of a collection. Clients should not rely on the remainingItemCount to be set or to be exact.
- The CustomResourceDefaulting feature is promoted to beta and enabled by default. Defaults may be specified in structural schemas via the
apiextensions.k8s.io/v1
API. See https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/#specifying-a-structural-schema for details. (#81872, @sttts) - kubectl could scale custom resource again (#81342, @knight42)
- a CSI driver that supports ephemeral inline volumes must explicitly declare that by providing a CSIDriver object where the new "mode" field is set to "ephemeral" or "persistent+ephemeral" (#80568, @pohly)
framework.ExpectNoError
no longer logs the error and instead relies on using the newlog.Fail
as Gomega fail handler. (#80253, @pohly)- Audit events now log the existence and patch of mutating webhooks. (#77824, @roycaihw) * At Metadata audit level or higher, an annotation with key "mutation.webhook.admission.k8s.io/round_{round idx}index{order idx}" gets logged with JSON payload indicating a webhook gets invoked for given request and whether it mutated the object or not. * At Request audit level or higher, an annotation with key "patch.webhook.admission.k8s.io/round_{round idx}index{order idx}" get logged with the JSON payload logging the patch sent by a webhook for given request.
- Resolves an issue that prevented block volumes from being resized. (#81429, @huffmanca)
- Verify that CRD default values in OpenAPI specs are pruned, with the exceptions of values under
metadata
. (#78829, @sttts) - Use PostFilter instead of Postfilter in the scheduling framework (#81800, @draveness)

- Use PreBind instead of Prebind in the scheduling framework
- Fix
kubectl logs -f
for windows server containers. (#81747, @Random-Liu) - fix azure disk naming matching issue due to case sensitive comparison (#81720, @andyzhangx)
- Fixes a bug that when there is a "connection refused" error, the reflector's ListAndWatch func will return directly but what expected is that sleep 1 second and rewatch since the specified resourceVersion. (#81634, @likakuli)
- Fixed a bug with the openAPI definition for io.k8s.apimachinery.pkg.runtime.RawExtension, which previously required a field "raw" to be specified (#80773, @jennybuckley)
- kubeadm: print the stack trace of an error for klog level --v>=5 (#80937, @neolit123)

- kubeadm: support any Linux kernel version newer than 3.10 (#81623, @neolit123)
- Added a metric 'apiserver_watch_events_sizes' that can be used to estimate sizes of watch events in the system. (#80477, @mborsz)
- NormalizeScore plugin set is removed from scheduler framework config API. Use ScorePlugin only. (#80930, @liu-cong)

- Add --shutdown-delay-duration to kube-apiserver in order to delay a graceful shutdown.
/healthz

- add
kubectl replace --raw
andkubectl delete --raw
to have parity with create and get (#79724, @deads2k) - E2E tests no longer add command line flags directly to the command line, test suites that want that need to be updated if they don't use HandleFlags (#75593, @pohly)
- loading a -viper-config=e2e.yaml with suffix (introduced in 1.13) works again and now has a regression test
- Kubernetes now supports transparent compression of API responses. Clients that send
Accept-Encoding: gzip
will now receive a GZIP compressed response body if the API call was larger than 128KB. Go clients automatically request gzip-encoding by default and should see reduced transfer times for very large API requests. Clients in other languages may need to make changes to benefit from compression. (#77449, @smarterclayton) - Resolves an issue serving aggregated APIs backed by services that respond to requests to
/
with non-2xx HTTP responses (#79895, @deads2k) - updated fluentd to 1.5.1, elasticsearchs & kibana to 7.1.1 (#79014, @monotek)
- kubeadm: implement support for concurrent add/remove of stacked etcd members (#79677, @neolit123)

- KMS Providers will install a healthz check for the status of kms-pluign in kube-apiservers' encryption config. (#78540, @immutableT)
- Fixes a bug in openapi published for custom resources using x-kubernetes-preserve-unknown-fields extensions, so that kubectl will allow sending unknown fields for that portion of the object. (#79636, @liggitt)
- A new client
k8s.io/client-go/metadata.Client
has been added for accessing objects generically. This client makes it easier to retrieve only the metadata (themetadata
sub-section) from resources on the cluster in an efficient manner for use cases that deal with objects generically, like the garbage collector, quota, or the namespace controller. The client asks the server to return ameta.k8s.io/v1 PartialObjectMetadata
object for list, get, delete, watch, and patch operations on both normal APIs and custom resources which can be encoded in protobuf for additional work. If the server does not yet support this API the client will gracefully fall back to JSON and transform the response objects into PartialObjectMetadata.

- To configure controller manager to use ipv6dual stack: (#73977, @khenidak)
-
use --cluster-cidr=",".
-
Notes:
-
- Only the first two cidrs are used (soft limits for Alpha, might be lifted later on).
-
- Only the "RangeAllocator" (default) is allowed as a value for --cidr-allocator-type . Cloud allocators are not compatible with ipv6dualstack
-
- When using the conformance test image, a new environment variable E2E_USE_GO_RUNNER will cause the tests to be run with the new Golang-based test runner rather than the current bash wrapper. (#79284, @johnSchnake)
- kubeadm: prevent PSP blocking of upgrade image prepull by using a non-root user (#77792, @neolit123)

- Addition of Overhead field to the PodSpec and RuntimeClass types as part of the Pod Overhead KEP (#76968, @egernst)
- fix pod list return value of framework.WaitForPodsWithLabelRunningReady (#78687, @pohly)
- The behavior of the default handler for 404 requests fro the GCE Ingress load balancer is slightly modified in the sense that it now exports metrics using prometheus. The metrics exported include: (#79106, @vbannai)
-
- http_404_request_total (the number of 404 requests handled)
-
- http_404_request_duration_ms (the amount of time the server took to respond in ms)
- Also includes percentile groupings. The directory for the default 404 handler includes instructions on how to enable prometheus for monitoring and setting alerts.
-
- The kube-apiserver has improved behavior for both startup and shutdown sequences and also now exposes
/readyz
for readiness checking. Readyz includes all existing healthz checks but also adds a shutdown check. When a cluster admin initiates a shutdown, the kube-apiserver will try to process existing requests (for the duration of request timeout) before killing the apiserver process. (#78458, @logicalhan)- The apiserver also now takes an optional flag "--maximum-startup-sequence-duration". This allows you to explicitly define an upper bound on the apiserver startup sequences before healthz begins to fail. By keeping the kubelet liveness initial delay short, this can enable quick kubelet recovery as soon as we have a boot sequence which has not completed in our expected time frame, despite lack of completion from longer boot sequences (like RBAC). Kube-apiserver behavior when the value of this flag is zero is backwards compatible (this is as the defaulted value of the flag).
