Changelog since v1.11.3

Other notable changes

  • support cross resource group for azure file (#68117, @andyzhangx)
  • change default azure file mount permission to 0777 (#69854, @andyzhangx)
  • Scheduling conformance tests related to daemonsets should set the annotation that relaxes node selection restrictions, if any are set. This ensures conformance tests can run on a wider array of clusters. (#68793, @aveshagarwal)
  • Add tolerations for Stackdriver Logging and Metadata Agents. (#69737, @qingling128)
  • Fix scheduler crashes when Prioritize Map function returns error. (#69618, @DylanBLE)
  • Add fallbacks to ARM API when getting empty node IP from Azure IMDS (#69077, @feiskyer)
  • Verify invalid secret/configmap/projected volumes before calling setup (#68691, @gnufied)
  • Immediately close the other side of the connection when proxying. (#67288, @MHBauer)
  • fix a bug that overwhelming number of prometheus metrics are generated because $NAMESPACE is not replaced by string "{namespace}" (#68530, @wenjiaswe)
  • locking fix in vSphere cleanup function (#68388, @wgliang)
    • The vSphere cloud provider has a cleanup function with a loop,
    • inside of which a write lock was intended to prevent races against
    • VM creation, but the usage of the sync.RWMutex type is incorrect,
    • plus is placed in a defer call so the locking is effectively
    • nonexistent. This patch adds an anonymous function call inside
    • the loop to correctly handle acquiring the write lock with deferred
    • unlock to run at that function's completion, following the normal
    • golang lock/deferred-unlock pattern.
  • fix UnmountDevice failure on Windows (#68608, @andyzhangx)
  • Get public IP for Azure vmss nodes. (#68498, @feiskyer)
  • Role, ClusterRole and their bindings for cloud-provider is put under system namespace. Their addonmanager mode switches to EnsureExists. (#67224, @grayluck)
  • Bump up version number of debian-base, debian-hyperkube-base and debian-iptables. (#67026, @satyasm)
    • Also updates dependencies of users of debian-base.
    • debian-base version 0.3.1 is already available.
  • Update debian-iptables and hyperkube-base images to include CVE fixes. (#67365, @ixdy)
  • Support configuring the Azure load balancer idle connection timeout for services (#66045, @cpuguy83)
  • Let service controller retry creating load balancer when persistUpdate failed due to conflict. (#68087, @grayluck)
  • Return apiserver panics as 500 errors instead terminating the apiserver process. (#68001, @sttts)
  • adjusted http/2 buffer sizes for apiservers to prevent starvation issues between concurrent streams (#67902, @liggitt)
  • Reduced excessive logging from fluentd-gcp-scaler. (#68837, @x13n)
  • Fix potential panic when getting azure load balancer status (#68609, @feiskyer)
  • Fix an issue where filesystems are not unmounted when a backend is not reachable and returns EIO. (#67097, @chakri-nelluri)
  • [GCE] Enable by default audit logging truncating backend. (#68342, @loburm)
  • [fluentd-gcp-scaler addon] Bump fluentd-gcp-scaler to 0.4 to pick up security fixes. (#67691, @loburm)
    • [prometheus-to-sd addon] Bump prometheus-to-sd to 0.3.1 to pick up security fixes, bug fixes and new features.
    • [event-exporter addon] Bump event-exporter to 0.2.3 to pick up security fixes.
  • [GCP] Added env variables to control CPU requests of kube-controller-manager and kube-scheduler. (#68823, @loburm)
  • Update Cluster Autoscaler to version 1.3.3. (#68936, @losipiuk)
  • Bump addon-manager to v8.7 (#68299, @MrHohn)
      • Support extra --prune-whitelist resources in kube-addon-manager.
      • Update kubectl to v1.10.7.
  • Support extra --prune-whitelist resources in kube-addon-manager. (#67743, @Random-Liu)
    • Before, when users run admission webhook as an addon pod, after they remove the webhook, kube-addon-manager won't cleanup the webhook configuration MutatingWebhookConfiguration/ValidationWebhookConfiguration, because those resources are not prune-whitelisted. Cluster will go into a bad state that no pod can be admitted.
    • With this feature, users can config kube-addon-manager to whitelist those resources to fix this issue.
  • Bump ip-masq-agent to v2.1.1 (#67916, @MrHohn)
      • Update debian-iptables image for CVEs.
      • Change chain name to IP-MASQ to be compatible with the
    • pre-injected masquerade rules.
  • If TaintNodesByCondition is enabled, add node.kubernetes.io/unschedulable and node.kubernetes.io/network-unavailable automatically to DaemonSet pods. (#64954, @k82cn)
  • Fix VMWare VM freezing bug by reverting #51066 (#67825, @nikopen)

Kubernetes 1.11 Release Notes

Urgent Upgrade Notes

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

Before upgrading to Kubernetes 1.11, you must keep the following in mind:

  • JSON configuration files that contain fields with incorrect case will no longer be valid. You must correct these files before upgrading. When specifying keys in JSON resource definitions during direct API server communication, the keys are case-sensitive. A bug introduced in Kubernetes 1.8 caused the API server to accept a request with incorrect case and coerce it to correct case, but this behaviour has been fixed in 1.11 and the API server will once again be enforcing the correct case. It’s worth noting that during this time, the kubectl tool continued to enforce case-sensitive keys, so users that strictly manage resources with kubectl will be unaffected by this change. (#65034, @caesarxuchao)
  • Pod priority and preemption is now enabled by default. Note that this means that pods from any namespace can now request priority classes that compete with and/or cause preemption of critical system pods that are already running. If that is not desired, disable the PodPriority feature by setting --feature-gates=PodPriority=false on the kube-apiserver, kube-scheduler, and kubelet components before upgrading to 1.11. Disabling the PodPriority feature limits critical pods to the kube-system namespace.

Major Themes

SIG API Machinery

This release SIG API Machinery focused mainly on CustomResources. For example, subresources for CustomResources are now beta and enabled by default. With this, updates to the /status subresource will disallow updates to all fields other than .status (not just .spec and .metadata as before). Also, required and description can be used at the root of the CRD OpenAPI validation schema when the /status subresource is enabled.

In addition, users can now create multiple versions of CustomResourceDefinitions, but without any kind of automatic conversion, and CustomResourceDefinitions now allow specification of additional columns for kubectl get output via the spec.additionalPrinterColumns field.

SIG Auth

Work this cycle focused on graduating existing functions, and on making security functions more understandable for users.

RBAC cluster role aggregation, introduced in 1.9, graduated to stable status with no changes in 1.11, and client-go credential plugins graduated to beta status, while also adding support for obtaining TLS credentials from an external plugin.

Kubernetes 1.11 also makes it easier to see what's happening, as audit events can now be annotated with information about how an API request was handled:

  • Authorization sets authorization.k8s.io/decision and authorization.k8s.io/reason annotations with the authorization decision ("allow" or "forbid") and a human-readable description of why the decision was made (for example, RBAC includes the name of the role/binding/subject which allowed a request).
  • PodSecurityPolicy admission sets podsecuritypolicy.admission.k8s.io/admit-policy and podsecuritypolicy.admission.k8s.io/validate-policy annotations containing the name of the policy that allowed a pod to be admitted. (PodSecurityPolicy also gained the ability to limit hostPath volume mounts to be read-only.)

In addition, the NodeRestriction admission plugin now prevents kubelets from modifying taints on their Node API objects, making it easier to keep track of which nodes should be in use.

SIG CLI

SIG CLI's main focus this release was on refactoring kubectl internals to improve composability, readability and testability of kubectl commands. Those refactors will allow the team to extract a mechanism for extensibility of kubectl -- that is, plugins -- in the next releases.

SIG Cluster Lifecycle

SIG Cluster Lifecycle focused on improving kubeadm’s user experience by including a set of new commands related to maintaining the kubeadm configuration file, the API version of which has now has been incremented to v1alpha2. These commands can handle the migration of the configuration to a newer version, printing the default configuration, and listing and pulling the required container images for bootstrapping a cluster.

Other notable changes include:

  • CoreDNS replaces kube-dns as the default DNS provider
  • Improved user experience for environments without a public internet connection and users using other CRI runtimes than Docker
  • Support for structured configuration for the kubelet, which avoids the need to modify the systemd drop-in file
  • Many improvements to the upgrade process and other bug fixes

SIG Instrumentation

As far as Sig Instrumentation, the major change in Kubernetes 1.11 is the deprecation of Heapster as part of ongoing efforts to move to the new Kubernetes monitoring model. Clusters still using Heapster for autoscaling should be migrated over to metrics-server and the custom metrics API. See the deprecation section for more information.

SIG Network

The main milestones for SIG Network this release are the graduation of IPVS-based load balancing and CoreDNS to general availability.

IPVS is an alternative approach to in-cluster load balancing that uses in-kernel hash tables rather than the previous iptables approach, while CoreDNS is a replacement for kube-dns for service discovery.

SIG Node

SIG-Node advanced several features and made incremental improvements in a few key topic areas this release.

The dynamic kubelet config feature graduated to beta, so it is enabled by default, simplifying management of the node object itself. Kubelets that are configured to work with the CRI may take advantage of the log rotation feature, which is graduating to beta this release.

The cri-tools project, which aims to provide consistent tooling for operators to debug and introspect their nodes in production independent of their chosen container runtime, graduated to GA.

As far as platforms, working with SIG-Windows, enhancements were made to the kubelet to improve platform support on Windows operating systems, and improvements to resource management were also made. In particular, support for sysctls on Linux graduated to beta.

SIG OpenStack

SIG-OpenStack continued to build out testing, with eleven acceptance tests covering a wide-range of scenarios and use-cases. During the 1.11 cycle our reporting back to test-grid has qualified the OpenStack cloud provider as a gating job for the Kubernetes release.

New features include improved integration between the Keystone service and Kubernetes RBAC, and a number of stability and compatibility improvements across the entire provider code-base.

SIG Scheduling

Pod Priority and Preemption has graduated to Beta, so it is enabled by default. Note that this involves significant and important changes for operators. The team also worked on improved performance and reliability of the scheduler.

SIG Storage

Sig Storage graduated two features that had been introduced in previous versions and introduced three new features in an alpha state.

The StorageProtection feature, which prevents deletion of PVCs while Pods are still using them and of PVs while still bound to a PVC, is now generally available, and volume resizing, which lets you increase size of a volume after a Pod restarts is now beta, which means it is on by default.

New alpha features include:

  • Online volume resizing will increase the filesystem size of a resized volume without requiring a Pod restart.
  • AWS EBS and GCE PD volumes support increased limits on the maximum number of attached volumes per node.
  • Subpath volume directories can be created using DownwardAPI environment variables.

SIG Windows

This release supports more of Kubernetes API for pods and containers on Windows, including:

  • Metrics for Pod, Container, Log filesystem
  • The run_as_user security contexts
  • Local persistent volumes and fstype for Azure disk

Improvements in Windows Server version 1803 also bring new storage functionality to Kubernetes v1.11, including:

  • Volume mounts for ConfigMap and Secret
  • Flexvolume plugins for SMB and iSCSI storage are also available out-of-tree at Microsoft/K8s-Storage-Plugins

Known Issues

  • IPVS based kube-proxy doesn't support graceful close connections for terminating pod. This issue will be fixed in a future release. (#57841, @jsravn)
  • kube-proxy needs to be configured to override hostname in some environments. (#857, @detiber)
  • There's a known issue where the Vertical Pod Autoscaler will radically change implementation in 1.12, so users of VPA (alpha) in 1.11 are warned that they will not be able to automatically migrate their VPA configs from 1.11 to 1.12.

Before Upgrading

  • When Response is a metav1.Status, it is no longer copied into the audit.Event status. Only the "status", "reason" and "code" fields are set. For example, when we run kubectl get pods abc, the API Server returns a status object: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"pods \"abc\" not found","reason":"NotFound","details":{"name":"abc","kind":"pods"},"code":404} In previous versions, the whole object was logged in audit events. Starting in 1.11, only status, reason, and code are logged. Code that relies on the older version must be updated to avoid errors. (#62695, @CaoShuFeng)
  • HTTP transport now uses context.Context to cancel dial operations. k8s.io/client-go/transport/Config struct has been updated to accept a function with a context.Context parameter. This is a breaking change if you use this field in your code. (#60012, @ash2k)
  • kubectl: This client version requires the apps/v1 APIs, so it will not work against a cluster version older than v1.9.0. Note that kubectl only guarantees compatibility with clusters that are +/-1 minor version away. (#61419, @enisoc)
  • Pod priority and preemption is now enabled by default. Even if you don't plan to use this feature, you might need to take some action immediately after upgrading. In multi-tenant clusters where not all users are trusted, you are advised to create appropriate quotas for two default priority classes, system-cluster-critical and system-node-critical, which are added to clusters by default. ResourceQuota should be created to limit users from creating Pods at these priorities if not all users of your cluster are trusted. We do not advise disabling this feature because critical system Pods rely on the scheduler preemption to be scheduled when cluster is under resource pressure.
  • Default mount propagation has changed from HostToContainer ("rslave" in Linux terminology), as it was in 1.10, to None ("private") to match the behavior in 1.9 and earlier releases; HostToContainer as a default caused regressions in some pods. If you are relying on this behavior you will need to set it explicitly. (#62462, @jsafrane)
  • The kube-apiserver --storage-version flag has been removed; you must use --storage-versions instead. (#61453, @hzxuzhonghu)
  • Authors of aggregated API servers must not rely on authorization being done by the kube-apiserver, and must do delegated authorization in addition. (#61349, @sttts)
  • GC is now bound by QPS so if you need more QPS to avoid ratelimiting GC, you'll have to set it explicitly. (#63657, @shyamjvs)
  • kubeadm join is now blocking on the kubelet performing the TLS Bootstrap properly. Earlier, kubeadm join only did the discovery part and exited successfully without checking that the kubelet actually started properly and performed the TLS bootstrap correctly. Now, as kubeadm runs some post-join steps (for example, annotating the Node API object with the CRISocket), kubeadm join is now waiting for the kubelet to perform the TLS Bootstrap, and then uses that credential to perform further actions. This also improves the UX, as kubeadm will exit with a non-zero code if the kubelet isn't in a functional state, instead of pretending everything's fine. (#64792, @luxas)
  • The structure of the kubelet dropin in the kubeadm deb package has changed significantly. Instead of hard-coding the parameters for the kubelet in the dropin, a structured configuration file for the kubelet is used, and is expected to be present in /var/lib/kubelet/config.yaml. For runtime-detected, instance-specific configuration values, a environment file with dynamically-generated flags at kubeadm init or kubeadm join run time is used. Finally, if you want to override something specific for the kubelet that can't be done via the kubeadm Configuration file (which is preferred), you might add flags to the KUBELET_EXTRA_ARGS environment variable in either /etc/default/kubelet or /etc/sysconfig/kubelet, depending on the system you're running on. (#64780, @luxas)
  • The --node-name flag for kubeadm now dictates the Node API object name the kubelet uses for registration, in all cases but where you might use an in-tree cloud provider. If you're not using an in-tree cloud provider, --node-name will set the Node API object name. If you're using an in-tree cloud provider, you MUST make --node-name match the name the in-tree cloud provider decides to use. (#64706, @liztio)
  • The PersistentVolumeLabel admission controller is now disabled by default. If you depend on this feature (AWS/GCE) then ensure it is added to the --enable-admission-plugins flag on the kube-apiserver. (#64326, @andrewsykim)
  • kubeadm: kubelets in kubeadm clusters now disable the readonly port (10255). If you're relying on unauthenticated access to the readonly port, please switch to using the secure port (10250). Instead, you can now use ServiceAccount tokens when talking to the secure port, which will make it easier to get access to, for example, the /metrics endpoint of the kubelet, securely. (#64187, @luxas)
  • The formerly publicly-available cAdvisor web UI that the kubelet ran on port 4194 by default is now turned off by default. The flag configuring what port to run this UI on --cadvisor-port was deprecated in v1.10. Now the default is --cadvisor-port=0, in other words, to not run the web server. If you still need to run cAdvisor, the recommended way to run it is via a DaemonSet. Note that the --cadvisor-port will be removed in v1.12 (#63881, @luxas)

New Deprecations

  • As a reminder, etcd2 as a backend is deprecated and support will be removed in Kubernetes 1.13. Please ensure that your clusters are upgraded to etcd3 as soon as possible.
  • InfluxDB cluster monitoring has been deprecated as part of the deprecation of Heapster. Instead, you may use the metrics server. It's a simplified heapster that is able to gather and serve current metrics values. It provides the Metrics API that is used by kubectl top, and horizontal pod autoscaler. Note that it doesn't include some features of Heapster, such as short term metrics for graphs in kube-dashboard and dedicated push sinks, which proved hard to maintain and scale. Clusters using Heapster for transferring metrics into long-term storage should consider using their metric solution's native Kubernetes support, if present, or should consider alternative solutions. (#62328, @serathius)
  • The kubelet --rotate-certificates flag is now deprecated, and will be removed in a future release. The kubelet certificate rotation feature can now be enabled via the .RotateCertificates field in the kubelet's config file. (#63912, @luxas)
  • The kubeadm configuration file version has been upgraded from v1alpha1 to v1alpha2. v1alpha1 read support exists in v1.11, but will be removed in v1.12. (#63788, @luxas) The following PRs changed the API spec:
    • In the new v1alpha2 kubeadm Configuration API, the .CloudProvider and .PrivilegedPods fields don't exist anymore. Instead, you should use the out-of-tree cloud provider implementations, which are beta in v1.11.
    • If you have to use the legacy in-tree cloud providers, you can rearrange your config like the example below. If you need the cloud-config file (located in {cloud-config-path}), you can mount it into the API Server and controller-manager containers using ExtraVolumes, as in:
kind: MasterConfiguration
apiVersion: kubeadm.k8s.io/v1alpha2
apiServerExtraArgs:
  cloud-provider: "{cloud}"
  cloud-config: "{cloud-config-path}"
apiServerExtraVolumes:
- name: cloud
  hostPath: "{cloud-config-path}"
  mountPath: "{cloud-config-path}"
controllerManagerExtraArgs:
  cloud-provider: "{cloud}"
  cloud-config: "{cloud-config-path}"
controllerManagerExtraVolumes:
- name: cloud
  hostPath: "{cloud-config-path}"
  mountPath: "{cloud-config-path}"
  • If you need to use the .PrivilegedPods functionality, you can still edit the manifests in /etc/kubernetes/manifests/, and set .SecurityContext.Privileged=true for the apiserver and controller manager. (#63866, @luxas)
  • kubeadm: The Token-related fields in the MasterConfiguration object have now been refactored. Instead of the top-level .Token, .TokenTTL, .TokenUsages, .TokenGroups fields, there is now a BootstrapTokens slice of BootstrapToken objects that support the same features under the .Token, .TTL, .Usages, .Groups fields. (#64408, @luxas)
  • .NodeName and .CRISocket in the MasterConfiguration and NodeConfiguration v1alpha1 API objects are now .NodeRegistration.Name and .NodeRegistration.CRISocket respectively in the v1alpha2 API. The .NoTaintMaster field has been removed in the v1alpha2 API. (#64210, @luxas)
  • kubeadm: Support for .AuthorizationModes in the kubeadm v1alpha2 API has been removed. Instead, you can use the .APIServerExtraArgs and .APIServerExtraVolumes fields to achieve the same effect. Files using the v1alpha1 API and setting this field will be automatically upgraded to this v1alpha2 API and the information will be preserved. (#64068, @luxas)
  • The annotation service.alpha.kubernetes.io/tolerate-unready-endpoints is deprecated. Users should use Service.spec.publishNotReadyAddresses instead. (#63742, @thockin)
  • --show-all, which only affected pods, and even then only for human readable/non-API printers, is inert in v1.11, and will be removed in a future release. (#60793, @charrywanganthony)
  • The kubectl rolling-update is now deprecated. Use kubectl rollout instead. (#61285, @soltysh)
  • kube-apiserver: the default --endpoint-reconciler-type is now lease. The master-count endpoint reconciler type is deprecated and will be removed in 1.13. (#63383, @liggitt)
  • OpenStack built-in cloud provider is now deprecated. Please use the external cloud provider for OpenStack. (#63524, @dims)
  • The Kubelet's deprecated --allow-privileged flag now defaults to true. This enables users to stop setting --allow-privileged in order to transition to PodSecurityPolicy. Previously, users had to continue setting --allow-privileged, because the default was false. (#63442, @mtaufen)
  • The old dynamic client has been replaced by a new one. The previous dynamic client will exist for one release in client-go/deprecated-dynamic. Switch as soon as possible. (#63446, @deads2k)
  • In-tree support for openstack credentials is now deprecated. please use the "client-keystone-auth" from the cloud-provider-openstack repository. details on how to use this new capability is documented here (#64346, @dims)
  • The GitRepo volume type is deprecated. To provision a container with a git repo, mount an EmptyDir into an InitContainer that clones the repo using git, then moEmptyDir` into the Pod's container. (#63445, @ericchiang)
  • Alpha annotation for PersistentVolume node affinity has been removed. Update your PersistentVolumes to use the beta PersistentVolume.nodeAffinity field before upgrading to this release. (#61816, @wackxu )

Removed Deprecations

  • kubeadm has removed the .ImagePullPolicy field in the v1alpha2 API version. Instead it's set statically to IfNotPresent for all required images. If you want to always pull the latest images before cluster init (as Always would do), run kubeadm config images pull before each kubeadm init. If you don't want the kubelet to pull any images at kubeadm init time, for example if you don't have an internet connection, you can also run kubeadm config images pull before kubeadm init or side-load the images some other way (such as docker load -i image.tar). Having the images locally cached will result in no pull at runtime, which makes it possible to run without any internet connection. (#64096, @luxas)
  • kubeadm has removed .Etcd.SelfHosting from its configuration API. It was never used in practice (#63871, @luxas)
  • The deprecated and inactive option '--enable-custom-metrics' has been removed in 1.11. (#60699, @CaoShuFeng)
  • --include-extended-apis, which was deprecated back in #32894, has been removed. (#62803, @deads2k)
  • Kubelets will no longer set externalID in their node spec. This feature has been deprecated since v1.1. (#61877, @mikedanese)
  • The initresource admission plugin has been removed. (#58784, @wackxu)
  • ObjectMeta , ListOptions, and DeleteOptions have been removed from the core api group. Please reference them in meta/v1 instead. (#61809, @hzxuzhonghu)
  • The deprecated --mode flag in check-network-mode has been removed. (#60102, @satyasm)
  • Support for the alpha.kubernetes.io/nvidia-gpu resource, which was deprecated in 1.10, has been removed. Please use the resource exposed by DevicePlugins instead (nvidia.com/gpu). (#61498, @mindprince)
  • The kube-cloud-controller-manager flag --service-account-private-key-file has been removed. Use --use-service-account-credentials instead. (#60875, @charrywanganthony)
  • The rknetes code, which was deprecated in 1.10, has been removed. Use rktlet and CRI instead. (#61432, @filbranden)
  • DaemonSet scheduling associated with the alpha ScheduleDaemonSetPods feature flag has been emoved. See https://github.com/kubernetes/features/issues/548 for feature status. (#61411, @liggitt)
  • The METADATA_AGENT_VERSION configuration option has been removed to keep metadata agent version consistent across Kubernetes deployments. (#63000, @kawych)
  • The deprecated --service-account-private-key-file flag has been removed from the cloud-controller-manager. The flag is still present and supported in the kube-controller-manager. (#65182, @liggitt)
  • Removed alpha functionality that allowed the controller manager to approve kubelet server certificates. This functionality should be replaced by automating validation and approval of node server certificate signing requests. (#62471, @mikedanese)

  • Added Establishing Controller on CRDs to avoid race between Established condition and CRs actually served. In HA setups, the Established condition is delayed by 5 seconds. (#63068, @xmudrii)
  • Added spec.additionalPrinterColumns to CRDs to define server side printing columns. (#60991, @sttts)
  • Added CRD Versioning with NOP converter (#63830, @mbohlool)
  • Allow "required" and "description" to be used at the CRD OpenAPI validation schema root when the /status subresource is enabled. (#63533, @sttts)
  • Etcd health checks by the apiserver now ensure the apiserver can connect to and exercise the etcd API. (#65027, @liggitt) api- machinery
  • The deprecated --service-account-private-key-file flag has been removed from the cloud-controller-manager. The flag is still present and supported in the kube-controller-manager. (#65182, @liggitt)
  • Webhooks for the mutating admission controller now support the "remove" operation. (#64255, @rojkov) sig-API machinery
  • The CRD OpenAPI v3 specification for validation now allows additionalProperties, which are mutually exclusive to properties. (#62333, @sttts)
  • Added the apiserver configuration option to choose the audit output version. (#60056, @crassirostris)
  • Created a new dryRun query parameter for mutating endpoints. If the parameter is set, then the query will be rejected, as the feature is not implemented yet. This will allow forward compatibility with future clients; otherwise, future clients talking with older apiservers might end up modifying a resource even if they include the dryRun query parameter. (#63557, @apelisse)
  • list/watch API requests with a fieldSelector that specifies metadata.name can now be authorized as requests for an individual named resource (#63469, @wojtek-t)
  • Exposed /debug/flags/v to allow dynamically set glog logging level. For example, to change glog level to 3, send a PUT request such as curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3". (#63777, @hzxuzhonghu)
  • Exec authenticator plugin supports TLS client certificates. (#61803, @awly)
  • The serverAddressByClientCIDRs property in metav1.APIGroup(discovery API) is now optional instead of required. (#61963, @roycaihw)
  • apiservices/status and certificatesigningrequests/status now support GET and PATCH (#64063, @roycaihw)
  • APIServices with kube-like versions (e.g. v1, v2beta1, etc.) will be sorted appropriately within each group. (#64004, @mbohlool)
  • Event object references with apiversion will now that value. (#63913, @deads2k)
  • Fixes the kubernetes.default.svc loopback service resolution to use a loopback configuration. (#62649, @liggitt)

SIG Apps

SIG Auth

  • RBAC information is now included in audit logs via audit.Event annotations:
    • authorization.k8s.io/decision = {allow, forbid}
    • authorization.k8s.io/reason = human-readable reason for the decision (#58807, @CaoShuFeng)
  • kubectl certificate approve|deny will not modify an already approved or denied CSR unless the --force flag is provided. (#61971, @smarterclayton)
  • The --bootstrap-kubeconfig argument to Kubelet previously created the first bootstrap client credentials in the certificates directory as kubelet-client.key and kubelet-client.crt. Subsequent certificates created by cert rotation were created in a combined PEM file that was atomically rotated as kubelet-client-DATE.pem in that directory, which meant clients relying on the node.kubeconfig generated by bootstrapping would never use a rotated cert. The initial bootstrap certificate is now generated into the cert directory as a PEM file and symlinked to kubelet-client-current.pem so that the generated kubeconfig remains valid after rotation. (#62152, @smarterclayton)
  • Owner references can now be set during creation, even if the user doesn't have deletion power (#63403, @deads2k)
  • Laid the groundwork for OIDC distributed claims handling in the apiserver authentication token checker. A distributed claim allows the OIDC provider to delegate a claim to a separate URL. (ref). (#63213, @filmil)
  • RBAC: all configured authorizers are now checked to determine if an RBAC role or clusterrole escalation (setting permissions the user does not currently have via RBAC) is allowed. (#56358, @liggitt)
  • kube-apiserver: OIDC authentication now supports requiring specific claims with --oidc-required-claim=<claim>=<value> Previously, there was no mechanism for a user to specify claims in the OIDC authentication process that were requid to be present in the ID Token with an expected value. This version now makes it possible to require claims support for the OIDC authentication. It allows users to pass in a --oidc-required-claims flag, and key=value pairs in the API config, which will ensure that the specified required claims are checked against the ID Token claims. (#62136, @rithujohn191)
  • Included the list of security groups when failing with the errors that more than one is tagged. (#58874, @sorenmat)
  • Added proxy for container streaming in kubelet for streaming auth. (#64006, @Random-Liu)
  • PodSecurityPolicy admission information has been added to audit logs. (#58143, @CaoShuFeng)
  • TokenRequests now are required to have an expiration duration between 10 minutes and 2^32 seconds. (#63999, @mikedanese)
  • The NodeRestriction admission plugin now prevents kubelets from modifying/removing taints applied to their Node API object. (#63167, @liggitt)
  • authz: nodes should not be able to delete themselves (#62818, @mikedanese)

SIG Autoscaling

  • A cluster-autoscaler ClusterRole is added to cover only the functionality required by Cluster Autoscaler and avoid abusing system:cluster-admin role. Cloud providers other than GCE might want to update their deployments or sample yaml files to reuse the role created via add-on. (#64503, @kgolab)

SIG Azure

  • The Azure cloud provider now supports standard SKU load balancer and public IP. excludeMasterFromStandardLB defaults to true, which means master nodes are excluded from the standard load balancer. Also note that because all nodes (except master) are added as loadbalancer backends, the standard load balancer doesn't work with the service.beta.kubernetes.io/azure-load-balancer-mode annotation. (#61884, #62707, @feiskyer)
  • The Azure cloud provider now supports specifying allowed service tags by the service.beta.kubernetes.io/azure-allowed-service-tags annotation. (#61467, @feiskyer)
  • You can now change the size of an azuredisk PVC using kubectl edit pvc pvc-azuredisk. Note that this operation will fail if the volume is already attached to a running VM. (#64386, @andyzhangx)
  • Block device support has been added for azure disk. (#63841, @andyzhangx)
  • Azure VM names can now contain the underscore (_) character (#63526, @djsly)
  • Azure disks now support external resource groups. (#64427, @andyzhangx)
  • Added reason message logs for non-existant Azure resources. (#64248, @feiskyer)

SIG CLI

  • You can now use the base64decode function in kubectl go templates to decode base64-encoded data, such as kubectl get secret SECRET -o go-template='{{ .data.KEY | base64decode }}'. (#60755, @glb)
  • kubectl patch now supports --dry-run. (#60675, @timoreimann)
  • The global flag --match-server-version is now global. kubectl version will respect it. (#63613, @deads2k)
  • kubectl will list all allowed print formats when an invalid format is passed. (#64371, @CaoShuFeng)
  • The global flag "context" now gets applied to kubectl config view --minify. In previous versions, this command was only available for current-context. Now it will be easier for users to view other non current contexts when minifying. (#64608, @dixudx)
  • kubectl apply --prune supports CronJob resources. (#62991, @tomoe)
  • The --dry-run flag has been enabled for kubectl auth reconcile (#64458, @mrogers950)
  • kubectl wait is a new command that allows waiting for one or more resources to be deleted or to reach a specific condition. It adds a kubectl wait --for=[delete|condition=condition-name] resource/string command. (#64034, @deads2k)
  • kubectl auth reconcile only works with rbac.v1; all the core helpers have been switched over to use the external types. (#63967, @deads2k)
  • kubectl and client-go now detect duplicated names for user, cluster and context when loading kubeconfig and report this condition as an error. (#60464, @roycaihw)
  • Added 'UpdateStrategyType' and 'RollingUpdateStrategy' to 'kubectl describe sts' command output. (#63844, @tossmilestone)
  • Initial Korean translation for kubectl has been added. (#62040, @ianychoi)
  • kubectl cp now supports completion. (#60371, @superbrothers)
  • The shortcuts that were moved server-side in at least 1.9 have been removed from being hardcoded in kubectl. This means that the client-based restmappers have been moved to client-go, where everyone who needs them can have access. (#63507, @deads2k)
  • When using kubectl delete with selection criteria, the defaults to is now to ignore "not found" errors. Note that this does not apply when deleting a speciic resource. (#63490, @deads2k)
  • kubectl create [secret | configmap] --from-file now works on Windows with fully-qualified paths (#63439, @liggitt)
  • Portability across systems has been increased by the use of /usr/bin/env in all script shebangs. (#62657, @matthyx)
  • You can now use kubectl api-resources to discover resources. (#42873, @xilabao)
  • You can now display requests/limits of extended resources in node allocated resources. (#46079, @xiangpengzhao)
  • The --remove-extra-subjects and --remove-extra-permissions flags have been enabled for kubectl auth reconcile (#64541, @mrogers950)
  • kubectl now has improved compatibility with older servers when creating/updating API objects (#61949, @liggitt)
  • kubectl apply view/edit-last-applied now supports completion. (#60499, @superbrothers)

SIG Cluster Lifecycle

  • kubeadm: The :Etcd struct has been refactored in the v1alpha2 API. All the options now reside under either .Etcd.Local or .Etcd.External. Automatic conversions from the v1alpha1 API are supported. (#64066, @luxas)
  • kubeadm now uses an upgraded API version for the configuration file, kubeadm.k8s.io/v1alpha2. kubeadm in v1.11 will still be able to read v1alpha1 configuration, and will automatically convert the configuration to v1alpha2, both internally and when storing the configuration in the ConfigMap in the cluster. (#63788, @luxas)
  • Phase kubeadm alpha phase kubelet has been added to support dynamic kubelet configuration in kubeadm. (#57224, @xiangpengzhao)
  • The kubeadm config option API.ControlPlaneEndpoint has been extended to take an optional port, which may differ from the apiserver's bind port. (#62314, @rjosephwright)
  • The --cluster-name parameter has been added to kubeadm init, enabling users to specify the cluster name in kubeconfig. (#60852, @karan)
  • The logging feature for kubeadm commands now supports a verbosity setting. (#57661, @vbmade2000)
  • kubeadm now has a join timeout that can be controlled via the discoveryTimeout config option. This option is set to 5 minutes by default. (#60983, @rosti)
  • Added the writable boolean option to kubeadm config. This option works on a per-volume basis for ExtraVolumes config keys. (#60428, @rosti)
  • Added a new kubeadm upgrade node config command. (#64624, @luxas)
  • kubeadm now makes the CoreDNS container more secure by dropping (root) capabilities and improves the integrity of the container by running the whole container in read-only. (#64473, @nberlee)
  • kubeadm now detects the Docker cgroup driver and starts the kubelet with the matching driver. This eliminates a common error experienced by new users in when the Docker cgroup driver is not the same as the one set for the kubelet due to different Linux distributions setting different cgroup drivers for Docker, making it hard to start the kubelet properly. (#64347, @neolit123)
  • Added a 'kubeadm config migrate' command to convert old API types to their newer counterparts in the new, supported API types. This is just a client-side tool; it just executes locally without requiring a cluster to be running, operating in much the same way as a Unix pipe that upgrades config files. (#64232, @luxas)
  • kubeadm will now pull required images during preflight checks if it cannot find them on the system. (#64105, @chuckha)
  • "kubeadm init" now writes a structured and versioned kubelet ComponentConfiguration file to /var/lib/kubelet/config.yaml and an environment file with runtime flags that you can source in the systemd kubelet dropin to /var/lib/kubelet/kubeadm-flags.env. (#63887, @luxas)
  • A kubeadm config print-default command has now been added. You can use this command to output a starting point when writing your own kubeadm configuration files. (#63969, @luxas)
  • Updated kubeadm's minimum supported kubernetes in v1.11.x to 1.10 (#63920, @dixudx)
  • Added the kubeadm upgrade diff command to show how static pod manifests will be changed by an upgrade. This command shows the changes that will be made to the static pod manifests before applying them. This is a narrower case than kubeadm upgrade apply --dry-run, which specifically focuses on the static pod manifests. (#63930, @liztio)
  • The kubeadm config images pull command can now be used to pull container images used by kubeadm. (#63833, @chuckha)
  • kubeadm will now deploy CoreDNS by default instead of KubeDNS (#63509, @detiber)
  • Preflight checks for kubeadm no longer validate custom kube-apiserver, kube-controller-manager and kube-scheduler arguments. (#63673, @chuckha)
  • Added a kubeadm config images list command that lists required container images for a kubeadm install. (#63450, @chuckha)
  • You can now use kubeadm token specifying --kubeconfig. In this case, kubeadm searches the current user home path and the environment variable KUBECONFIG for existing files. If provided, the --kubeconfig flag will be honored instead. (#62850, @neolit123) (#64988, @detiber)
  • kubeadm now sets peer URLs for the default etcd instance. Previously we left the defaults, which meant the peer URL was unsecured.
  • Kubernetes now packages crictl in a cri-tools deb and rpm package. (#64836, @chuckha)
  • kubeadm now prompts the user for confirmation when resetting a master node. (#59115, @alexbrand)
  • kubead now creates kube-proxy with a toleration to run on all nodes, no matter the taint. (#62390, @discordianfish)
  • kubeadm now sets the kubelet --resolv-conf flag conditionally on init. (#64665, @stealthybox)
  • Added ipset and udevadm to the hyperkube base image. (#61357, @rphillips)

SIG GCP

  • Kubernetes clusters on GCE now have crictl installed. Users can use it to help debug their nodes. See the crictl documentation for details. (#63357, @Random-Liu)
  • cluster/kube-up.sh now provisions a Kubelet config file for GCE via the metadata server. This file is installed by the corresponding GCE init scripts. (#62183, @mtaufen)
  • GCE: Update cloud provider to use TPU v1 API (#64727, @yguo0905)
  • GCE: Bump GLBC version to 1.1.1 - fixing an issue of handling multiple certs with identical certificates. (#62751, @nicksardo)

SIG Instrumentation

  • Added prometheus cluster monitoring addon to kube-up. (#62195, @serathius)
  • Kubelet now exposes a new endpoint, /metrics/probes, which exposes a Prometheus metric containing the liveness and/or readiness probe results for a container. (#61369, @rramkumar1)

SIG Network

  • The internal IP address of the node is now added as additional information for kubectl. (#57623, @dixudx)
  • NetworkPolicies can now target specific pods in other namespaces by including both a namespaceSelector and a podSelector in the same peer element. (#60452, @danwinship)
  • CoreDNS deployment configuration now uses the k8s.gcr.io imageRepository. (#64775, @rajansandeep)
  • kubelet's --cni-bin-dir option now accepts multiple comma-separated CNI binary directory paths, which are searched for CNI plugins in the given order. (#58714, @dcbw)
  • You can now use --ipvs-exclude-cidrs to specify a list of CIDR's which the IPVS proxier should not touch when cleaning up IPVS rules. (#62083, @rramkumar1)
  • You can now receive node DNS info with the --node-ip flag, which adds ExternalDNS, InternalDNS, and ExternalIP to kubelet's output. (#63170, @micahhausler)
  • You can now have services that listen on the same host ports on different interfaces by specifying --nodeport-addresses. (#62003, @m1093782566)
  • Added port-forward examples for service

SIG Node

  • CRI: The container log path has been changed from containername_attempt#.log to containername/attempt#.log (#62015, @feiskyer)
  • Introduced the ContainersReady condition in Pod status. (#64646, @freehan)
  • Kubelet will now set extended resource capacity to zero after it restarts. If the extended resource is exported by a device plugin, its capacity will change to a valid value after the device plugin re-connects with the Kubelet. If the extended resource is exported by an external component through direct node status capacity patching, the component should repatch the field after kubelet becomes ready again. During the time gap, pods previously assigned with such resources may fail kubelet admission but their controller should create new pods in response to such failures. (#64784, @jiayingz) node
  • You can now use a security context with Windows containers (#64009, @feiskyer)
  • Added e2e regression tests for kubelet security. (#64140, @dixudx)
  • The maximum number of images the Kubelet will report in the Node status can now be controlled via the Kubelet's --node-status-max-images flag. The default (50) remains the same. (#64170, @mtaufen)
  • The Kubelet now exports metrics that report the assigned (node_config_assigned), last-known-good (node_config_last_known_good), and active (node_config_active) config sources, and a metric indicating whether the node is experiencing a config-related error (node_config_error). The config source metrics always report the value 1, and carry the node_config_name, node_config_uid, node_config_resource_version, and node_config_kubelet_key labels, which identify the config version. The error metric reports 1 if there is an error, 0 otherwise. (#57527, @mtaufen)
  • You now have the ability to quota resources by priority. (#57963, @vikaschoudhary16)
  • The gRPC max message size in the remote container runtime has been increased to 16MB. (#64672, @mcluseau)
  • Added a feature gate for the plugin watcher. (#64605, @vikaschoudhary16)
  • The status of dynamic Kubelet config is now reported via Node.Status.Config, rather than the KubeletConfigOk node condition. (#63314, @mtaufen)
  • You must now specify Node.Spec.ConfigSource.ConfigMap.KubeletConfigKey when using dynamic Kubelet config to tell the Kubelet which key of the ConfigMap identifies its config file. (#59847, @mtaufen)
  • The dynamic Kubelet config feature will now update the config in the event of a ConfigMap mutation, which reduces the chance for silent config skew. Only name, namespace, and kubeletConfigKey may now be set in Node.Spec.ConfigSource.ConfigMap. The least disruptive pattern for config management is still to create a new ConfigMap and incrementally roll out a new Node.Spec.ConfigSource. (#63221, @mtaufen)
  • Change seccomp annotation from "docker/default" to "runtime/default" (#62662, @wangzhen127)
  • The node authorizer now automatically sets up rules for Node.Spec.ConfigSource when the DynamicKubeletConfig feature gate is enabled. (#60100, @mtaufen)
  • CRI now defines mounting behavior. If the host path doesn't exist, the runtime should return an error. If the host path is a symlink, the runtime should follow the symlink and mount the real destination to the container. (#61460, @feiskyer)

SIG OpenStack

  • Provide a meaningful error message in the openstack cloud provider when no valid IP address can be found for a node, rather than just the first address of the node, which leads to a load balancer error if that address is a hostname or DNS name instead of an IP address. (#64318, @gonzolino)
  • Restored the pre-1.10 behavior of the openstack cloud provider, which uses the instance name as the Kubernetes Node name. This requires instances be named with RFC-1123 compatible names. (#63903, @liggitt)
  • Kubernetes will try to read the openstack auth config from the client config and fall back to read from the environment variables if the auth config is not available. (#60200, @dixudx)

SIG Scheduling

  • Schedule DaemonSet Pods in scheduler, rather than the Daemonset controller. (#63223, @k82cn)
  • Added MatchFields to NodeSelectorTerm; in 1.11, it only supports metadata.name. (#62002, @k82cn)
  • kube-scheduler now has the --write-config-to flag so that Scheduler canwritets default configuration to a file. (#62515, @resouer)
  • Performance of the affinity/anti-affinity predicate for the default scheduler has been significantly improved. (#62211, @bsalamat)
  • The 'scheduling_latency_seconds' metric into has been split into finer steps (predicate, priority, preemption). (#65306, @shyamjvs)
  • Scheduler now has a summary-type metric, 'scheduling_latency_seconds'. (#64838, @krzysied)
  • nodeSelector.matchFields (node's metadata.node) is now supported in scheduler. (#62453, @k82cn)
  • Added a parametrizable priority function mapping requested/capacity ratio to priority. This function is disabled by default and can be enabled via the scheduler policy config file. (#63929, @losipiuk)
  • System critical priority classes are now automatically added at cluster boostrapping. (#60519, @bsalamat)

SIG Storage

  • AWS EBS, Azure Disk, GCE PD and Ceph RBD volume plugins now support dynamic provisioning of raw block volumes. (#64447, @jsafrane)
  • gitRepo volumes in pods no longer require git 1.8.5 or newer; older git versions are now supported. (#62394, @jsafrane)
  • Added support for resizing Portworx volumes. (#62308, @harsh-px)
  • Added block volume support to Cinder volume plugin. (#64879, @bertinatto)
  • Provided API support for external CSI storage drivers to support block volumes. (#64723, @vladimirvivien)
  • Volume topology aware dynamic provisioning for external provisioners is now supported. (#63193, @lichuqiang)
  • Added a volume projection that is able to project service account tokens. (#62005, @mikedanese)
  • PodSecurityPolicy now supports restricting hostPath volume mounts to be readOnly and under specific path prefixes (#58647, @jhorwit2)
  • Added StorageClass API to restrict topologies of dynamically provisioned volumes. (#63233, @lichuqiang)
  • Added Alpha support for dynamic volume limits based on node type (#64154, @gnufied)
  • AWS EBS volumes can be now used as ReadOnly in pods. (#64403, @jsafrane)
  • Basic plumbing for volume topology aware dynamic provisionin has been implemented. (#63232, @lichuqiang)
  • Changed ext3/ext4 volume creation to not reserve any portion of the volume for the root user. When creating ext3/ext4 volume, mkfs defaults to reserving 5% of the volume for the super-user (root). This patch changes the mkfs to pass -m0 to disable this setting. (#64102, @atombender)
  • Added support for NFS relations on kubernetes-worker charm. (#63817, @hyperbolic2346)
  • Implemented kubelet side online file system resizing (#62460, @mlmhl)
  • Generated subpath name from Downward API env (#49388, @kevtaylor)

SIG vSphere

  • Added a mechanism in vSphere Cloud Provider to get credentials from Kubernetes secrets, rather than the plain text vsphere.conf file.(#63902, @abrarshivani)
  • vSphere Cloud Provider: added SAML token authentication support (#63824, @dougm)

SIG Windows

  • Added log and fs stats for Windows containers. (#62266, @feiskyer)
  • Added security contexts for Windows containers. #64009, (@feiskyer)
  • Added local persistent volumes for Windows containers. (#62012, @andyzhangx) and fstype for Azure disk (#61267, @andyzhangx)
  • Improvements in Windows Server version 1803 also bring new storage functionality to Kubernetes v1.11, including:
    • Volume mounts for ConfigMap and Secret
    • Flexvolume plugins for SMB and iSCSI storage are also available out-of-tree at Microsoft/K8s-Storage-Plugins
  • Setup dns servers and search domains for Windows Pods in dockershim. Docker EE version >= 17.10.0 is required for propagating DNS to containers. (#63905, @feiskyer)

Additional changes

  • increased grpc client default response size. (#63977, @runcom)
  • Applied pod name and namespace labels to pod cgroup in cAdvisor metrics (#63406, @derekwaynecarr)
  • [fluentd-gcp addon] Use the logging agent's node name as the metadata agent URL. (#63353, @bmoyles0117)
  • The new default value for the --allow-privileged parameter of the Kubernetes-worker charm has been set to true based on changes which went into the Kubernetes 1.10 release. Before this change the default value was set to false. If you're installing Canonical Kubernetes you should expect this value to now be true by default and you should now look to use PSP (pod security policies). (#64104, @CalvinHartwell)

  • Update crictl on GCE to v1.11.0. (#65254)
  • CoreDNS is now v1.1.3 (#64258)
  • Setup dns servers and search domains for Windows Pods in dockershim. Docker EE version >= 17.10.0 is required for propagating DNS to containers. (#63905)

Bug Fixes

  • Fixed spurious "unable to find api field" errors patching custom resources (#63146, @liggitt)
  • Nodes are not deleted from kubernetes anymore if node is shutdown in Openstack. (#59931, @zetaab)
  • Re-enabled nodeipam controller for external clouds. Re-enables nodeipam controller for external clouds. Also does a small refactor so that we don't need to pass in allocateNodeCidr into the controller. (#63049, @andrewsykim)
  • Fixed a configuration error when upgrading kubeadm from 1.9 to 1.10+; Kubernetes must have the same major and minor versions as the kubeadm library. (#62568, @liztio)
  • kubectl no longer renders a List as suffix kind name for CRD resources (#62512, @dixudx)
  • Restored old behavior to the --template flag in get.go. In old releases, providing a --template flag value and no --output value implicitly assigned a default value ("go-template") to --output, printing using the provided template argument. (#65377,@juanvallejo)
  • Ensured cloudprovider.InstanceNotFound is reported when the VM is not found on Azure (#61531, @feiskyer)
  • Kubernetes version command line parameter in kubeadm has been updated to drop an unnecessary redirection from ci/latest.txt to ci-cross/latest.txt. Users should know exactly where the builds are stored on Google Cloud storage buckets from now on. For example for 1.9 and 1.10, users can specify ci/latest-1.9 and ci/latest-1.10 as the CI build jobs what build images correctly updates those. The CI jobs for master update the ci-cross/latest location, so if you are looking for latest master builds, then the correct parameter to use would be ci-cross/latest. (#63504, @dims)
  • Fixes incompatibility with custom scheduler extender configurations specifying bindVerb (#65424, @liggitt)
  • kubectl built for darwin from darwin now enables cgo to use the system-native C libraries for DNS resolution. Cross-compiled kubectl (e.g. from an official kubernetes release) still uses the go-native netgo DNS implementation. (#64219, @ixdy)

Changelog since v1.11.0-beta.1

Action Required

  • [action required] kubeadm join is now blocking on the kubelet performing the TLS Bootstrap properly. (#64792, @luxas)
    • Earlier, kubeadm join only did the discovery part and exited successfully without checking that the
    • kubelet actually started properly and performed the TLS bootstrap correctly. Now, as kubeadm runs
    • some post-join steps (e.g. annotating the Node API object with the CRISocket as in this PR, as a
    • stop-gap until this is discoverable automatically), kubeadm join is now waiting for the kubelet to
    • perform the TLS Bootstrap, and then uses that credential to perform further actions. This also
    • improves the UX, as kubeadm will exit with a non-zero code if the kubelet isn't in a functional
    • state, instead of pretending like everything's fine.
  • [action required] The structure of the kubelet dropin in the kubeadm deb package has changed significantly. (#64780, @luxas)
    • Instead of hard-coding the parameters for the kubelet in the dropin, a structured configuration file
    • for the kubelet is used, and is expected to be present in /var/lib/kubelet/config.yaml.
    • For runtime-detected, instance-specific configuration values, a environment file with
    • dynamically-generated flags at kubeadm init or kubeadm join run time is used.
    • Finally, if the user wants to override something specific for the kubelet that can't be done via
    • the kubeadm Configuration file (which is preferred), they might add flags to the
    • KUBELET_EXTRA_ARGS environment variable in either /etc/default/kubelet
    • or /etc/sysconfig/kubelet, depending on the system you're running on.
  • [action required] The --node-name flag for kubeadm now dictates the Node API object name the (#64706, @liztio)
    • kubelet uses for registration, in all cases but where you might use an in-tree cloud provider.
    • If you're not using an in-tree cloud provider, --node-name will set the Node API object name.
    • If you're using an in-tree cloud provider, you MUST make --node-name match the name the
    • in-tree cloud provider decides to use.
  • [action required] kubeadm: The Token-related fields in the MasterConfiguration object have now been refactored. Instead of the top-level .Token, .TokenTTL, .TokenUsages, .TokenGroups fields, there is now a BootstrapTokens slice of BootstrapToken objects that support the same features under the .Token, .TTL, .Usages, .Groups fields. (#64408, @luxas)

Other notable changes

  • Add Vertical Pod Autoscaler to autoscaling/v2beta1 (#63797, @kgrygiel)
  • kubeadm: only run kube-proxy on architecture consistent nodes (#64696, @dixudx)
  • kubeadm: Add a new kubeadm upgrade node config command (#64624, @luxas)
  • Orphan delete is now supported for custom resources (#63386, @roycaihw)
  • Update version of Istio addon from 0.6.0 to 0.8.0. (#64537, @ostromart)
  • Provides API support for external CSI storage drivers to support block volumes. (#64723, @vladimirvivien)
  • kubectl will list all allowed print formats when an invalid format is passed. (#64371, @CaoShuFeng)
  • Use IONice to reduce IO priority of du and find (#64800, @dashpole)
    • cAdvisor ContainerReference no longer contains Labels. Use ContainerSpec instead.
    • Fix a bug where cadvisor failed to discover a sub-cgroup that was created soon after the parent cgroup.
  • Kubelet will set extended resource capacity to zero after it restarts. If the extended resource is exported by a device plugin, its capacity will change to a valid value after the device plugin re-connects with the Kubelet. If the extended resource is exported by an external component through direct node status capacity patching, the component should repatch the field after kubelet becomes ready again. During the time gap, pods previously assigned with such resources may fail kubelet admission but their controller should create new pods in response to such failures. (#64784, @jiayingz)
  • Introduce ContainersReady condition in Pod Status (#64646, @freehan)
  • The Sysctls experimental feature has been promoted to beta (enabled by default via the Sysctls feature flag). PodSecurityPolicy and Pod objects now have fields for specifying and controlling sysctls. Alpha sysctl annotations will be ignored by 1.11+ kubelets. All alpha sysctl annotations in existing deployments must be converted to API fields to be effective. (#63717, @ingvagabund)
  • kubeadm now configures the etcd liveness probe correctly when etcd is listening on all interfaces (#64670, @stealthybox)
  • Fix regression in v1.JobSpec.backoffLimit that caused failed Jobs to be restarted indefinitely. (#63650, @soltysh)

  • Kubelet: Add security context for Windows containers (#64009, @feiskyer)
  • Volume topology aware dynamic provisioning (#63193, @lichuqiang)

  • Add a volume projection that is able to project service account tokens. (#62005, @mikedanese)
  • Fix kubectl auth can-i exit code. It will return 1 if the user is not allowed and 0 if it's allowed. (#59579, @fbac)
  • apply global flag "context" for kubectl config view --minify (#64608, @dixudx)
  • Fix kube-controller-manager panic while provisioning Azure security group rules (#64739, @feiskyer)

  • Adding CSI driver registration code. (#64560, @sbezverk)
  • fixes a potential deadlock in the garbage collection controller (#64235, @liggitt)
  • Fixes issue for readOnly subpath mounts for SELinux systems and when the volume mountPath already existed in the container image. (#64351, @msau42)
  • Add log and fs stats for Windows containers (#62266, @feiskyer)
  • client-go: credential exec plugins have been promoted to beta (#64482, @ericchiang)
  • Revert #64364 to resurrect rescheduler. For More info see[#64725] https://github.com/kubernetes/kubernetes/issues/64725 and (#64592, @ravisantoshgudimetla)
  • Add RequestedToCapacityRatioPriority priority function. Function is parametrized with set of points mapping node utilization (0-100) to score (0-10). (#63929, @losipiuk)
    • Function is linear between points. Resource utilization is defined as one minus ratio of total amount of resource requested by pods on node and node's capacity (scaled to 100).
    • Final utilization used for computation is arithmetic mean of cpu utilization and memory utilization.
    • Function is disabled by default and can be enabled via scheduler policy config file.
    • If no parametrization is specified in config file it defaults to one which gives score 10 to utilization 0 and score 0 to utilization 100.
  • kubeadm init detects if systemd-resolved is running and configures the kubelet to use a working resolv.conf. (#64665, @stealthybox)
  • fix data loss issue if using existing azure disk with partitions in disk mount (#63270, @andyzhangx)
  • Meta data of CustomResources is now pruned and schema checked during deserialization of requests and when read from etcd. In the former case, invalid meta data is rejected, in the later it is dropped from the CustomResource objects. (#64267, @sttts)
  • Add Alpha support for dynamic volume limits based on node type (#64154, @gnufied)
  • Fixed CSI gRPC connection leak during volume operations. (#64519, @vladimirvivien)
  • in-tree support for openstack credentials is now deprecated. please use the "client-keystone-auth" from the cloud-provider-openstack repository. details on how to use this new capability is documented here - https://github.com/kubernetes/cloud-provider-openstack/blob/master/docs/using-client-keystone-auth.md (#64346, @dims)
  • ScheduleDaemonSetPods is an alpha feature (since v1.11) that causes DaemonSet Pods (#63223, @k82cn)
    • to be scheduler by default scheduler, instead of Daemonset controller. When it is enabled,
    • the NodeAffinity term (instead of .spec.nodeName) is added to the DaemonSet Pods;
    • this enables the default scheduler to bind the Pod to the target host. If node affinity
    • of DaemonSet Pod already exists, it will be replaced.
    • DaemonSet controller will only perform these operations when creating DaemonSet Pods;
    • and those operations will only modify the Pods of DaemonSet, no changes are made to the
    • .spec.template of DaemonSet.
  • fix formatAndMount func issue on Windows (#63248, @andyzhangx)
  • AWS EBS, Azure Disk, GCE PD and Ceph RBD volume plugins support dynamic provisioning of raw block volumes. (#64447, @jsafrane)
  • kubeadm upgrade apply can now ignore version errors with --force (#64570, @liztio)
  • Adds feature gate for plugin watcher (#64605, @vikaschoudhary16)
  • Kubelet now proxies container streaming between apiserver and container runtime. The connection between kubelet and apiserver is authenticated. Container runtime should change streaming server to serve on localhost, to make the connection between kubelet and container runtime local. (#64006, @Random-Liu)
    • In this way, the whole container streaming connection is secure. To switch back to the old behavior, set --redirect-container-streaming=true flag.
  • TokenRequests now are required to have an expiration duration between 10 minutes and 2^32 seconds. (#63999, @mikedanese)
  • Expose /debug/flags/v to allow dynamically set glog logging level, if want to change glog level to 3, you only have to send a PUT request with like curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3". (#63777, @hzxuzhonghu)
  • New conformance test added for Watch. (#61424, @jennybuckley)
  • The GitRepo volume type is deprecated. To provision a container with a git repo, mount an EmptyDir into an InitContainer that clones the repo using git, then mount the EmptyDir into the Pod's container. (#63445, @ericchiang)
  • kubeadm now preserves previous manifests after upgrades (#64337, @liztio)
  • Implement kubelet side online file system resizing (#62460, @mlmhl)

Changelog since v1.11.0-alpha.2

Action Required

  • [action required] .NodeName and .CRISocket in the MasterConfiguration and NodeConfiguration v1alpha1 API objects are now .NodeRegistration.Name and .NodeRegistration.CRISocket respectively in the v1alpha2 API. The .NoTaintMaster field has been removed in the v1alpha2 API. (#64210, @luxas)
  • (ACTION REQUIRED) PersisntVolumeLabel admission controller is now disabled by default. If you depend on this feature (AWS/GCE) then ensure it is added to the --enable-admission-plugins flag on the kube-apiserver. (#64326, @andrewsykim)
  • [action required] kubeadm: The :Etcd struct has been refactored in the v1alpha2 API. All the options now reside under either .Etcd.Local or .Etcd.External. Automatic conversions from the v1alpha1 API are supported. (#64066, @luxas)
  • [action required] kubeadm: kubelets in kubeadm clusters now disable the readonly port (10255). If you're relying on unauthenticated access to the readonly port, please switch to using the secure port (10250). Instead, you can now use ServiceAccount tokens when talking to the secure port, which will make it easier to get access to e.g. the /metrics endpoint of the kubelet securely. (#64187, @luxas)
  • [action required] kubeadm: Support for .AuthorizationModes in the kubeadm v1alpha2 API has been removed. Instead, you can use the .APIServerExtraArgs and .APIServerExtraVolumes fields to achieve the same effect. Files using the v1alpha1 API and setting this field will be automatically upgraded to this v1alpha2 API and the information will be preserved. (#64068, @luxas)
  • [action required] The formerly publicly-available cAdvisor web UI that the kubelet ran on port 4194 by default is now turned off by default. The flag configuring what port to run this UI on --cadvisor-port was deprecated in v1.10. Now the default is --cadvisor-port=0, in other words, to not run the web server. The recommended way to run cAdvisor if you still need it, is via a DaemonSet. The --cadvisor-port will be removed in v1.12 (#63881, @luxas)
  • [action required] kubeadm: The .ImagePullPolicy field has been removed in the v1alpha2 API version. Instead it's set statically to IfNotPresent for all required images. If you want to always pull the latest images before cluster init (like what Always would do), run kubeadm config images pull before each kubeadm init. If you don't want the kubelet to pull any images at kubeadm init time, as you for instance don't have an internet connection, you can also run kubeadm config images pull before kubeadm init or side-load the images some other way (e.g. docker load -i image.tar). Having the images locally cached will result in no pull at runtime, which makes it possible to run without any internet connection. (#64096, @luxas)
  • [action required] In the new v1alpha2 kubeadm Configuration API, the .CloudProvider and .PrivilegedPods fields don't exist anymore. (#63866, @luxas)
    • Instead, you should use the out-of-tree cloud provider implementations which are beta in v1.11.
    • If you have to use the legacy in-tree cloud providers, you can rearrange your config like the example below. In case you need the cloud-config file (located in {cloud-config-path}), you can mount it into the API Server and controller-manager containers using ExtraVolumes like the example below.
    • If you need to use the .PrivilegedPods functionality, you can still edit the manifests in /etc/kubernetes/manifests/, and set .SecurityContext.Privileged=true for the apiserver and controller manager.
kind: MasterConfiguration
apiVersion: kubeadm.k8s.io/v1alpha2
apiServerExtraArgs:
  cloud-provider: "{cloud}"
  cloud-config: "{cloud-config-path}"
apiServerExtraVolumes:
- name: cloud
  hostPath: "{cloud-config-path}"
  mountPath: "{cloud-config-path}"
controllerManagerExtraArgs:
  cloud-provider: "{cloud}"
  cloud-config: "{cloud-config-path}"
controllerManagerExtraVolumes:
- name: cloud
  hostPath: "{cloud-config-path}"
  mountPath: "{cloud-config-path}"
  • [action required] kubeadm now uses an upgraded API version for the configuration file, kubeadm.k8s.io/v1alpha2. kubeadm in v1.11 will still be able to read v1alpha1 configuration, and will automatically convert the configuration to v1alpha2 internally and when storing the configuration in the ConfigMap in the cluster. (#63788, @luxas)
  • The annotation service.alpha.kubernetes.io/tolerate-unready-endpoints is deprecated. Users should use Service.spec.publishNotReadyAddresses instead. (#63742, @thockin)
  • avoid duplicate status in audit events (#62695, @CaoShuFeng)

Other notable changes

  • Remove rescheduler from master. (#64364, @ravisantoshgudimetla)

  • kubeadm: conditionally set the kubelet cgroup driver for Docker (#64347, @neolit123)
  • kubectl built for darwin from darwin now enables cgo to use the system-native C libraries for DNS resolution. Cross-compiled kubectl (e.g. from an official kubernetes release) still uses the go-native netgo DNS implementation. (#64219, @ixdy)
  • AWS EBS volumes can be now used as ReadOnly in pods. (#64403, @jsafrane)
  • Exec authenticator plugin supports TLS client certificates. (#61803, @awly)

  • kubeadm: Add a 'kubeadm config migrate' command to convert old API types to their newer counterparts in the new, supported API types. This is just a client-side tool, it just executes locally without requiring a cluster to be running. You can think about this as an Unix pipe that upgrades config files. (#64232, @luxas)
  • The --dry-run flag has been enabled for kubectl auth reconcile (#64458, @mrogers950)
  • Add probe based mechanism for kubelet plugin discovery (#63328, @vikaschoudhary16)

  • CoreDNS is now v1.1.3 (#64258, @rajansandeep)
  • kubeadm will pull required images during preflight checks if it cannot find them on the system (#64105, @chuckha)
  • kubeadm: rename the addon parameter kube-dns to coredns for kubeadm alpha phases addons as CoreDNS is now the default DNS server in 1.11. (#64274, @neolit123)
  • kubeadm: when starting the API server use the arguments --enable-admission-plugins and --disable-admission-plugins instead of the deprecated --admission-control. (#64165, @neolit123)
  • Add spec.additionalPrinterColumns to CRDs to define server side printing columns. (#60991, @sttts)
  • fix azure file size grow issue (#64383, @andyzhangx)
  • Fix issue of colliding nodePorts when the cluster has services with externalTrafficPolicy=Local (#64349, @nicksardo)

  • Fail fast if cgroups-per-qos is set on Windows (#62984, @feiskyer)
  • Move Volume expansion to Beta (#64288, @gnufied)
  • kubectl delete does not use reapers for removing objects anymore, but relies on server-side GC entirely (#63979, @soltysh)
  • Basic plumbing for volume topology aware dynamic provisioning (#63232, @lichuqiang)
  • API server properly parses propagationPolicy as a query parameter sent with a delete request (#63414, @roycaihw)
  • Property serverAddressByClientCIDRs in metav1.APIGroup (discovery API) now become optional instead of required (#61963, @roycaihw)
  • The dynamic Kubelet config feature is now beta, and the DynamicKubeletConfig feature gate is on by default. In order to use dynamic Kubelet config, ensure that the Kubelet's --dynamic-config-dir option is set. (#64275, @mtaufen)
  • Add reason message logs for non-exist Azure resources (#64248, @feiskyer)
  • Fix SessionAffinity not updated issue for Azure load balancer (#64180, @feiskyer)
  • The kube-apiserver openapi doc now includes extensions identifying APIService and CustomResourceDefinition kinds (#64174, @liggitt)
  • apiservices/status and certificatesigningrequests/status now support GET and PATCH (#64063, @roycaihw)
  • kubectl: This client version requires the apps/v1 APIs, so it will not work against a cluster version older than v1.9.0. Note that kubectl only guarantees compatibility with clusters that are +/-1 minor version away. (#61419, @enisoc)
  • Correct the way we reset containers and pods in kubeadm via crictl (#63862, @runcom)
  • Allow env from resource with keys & updated tests (#60636, @PhilipGough)
  • The kubelet certificate rotation feature can now be enabled via the .RotateCertificates field in the kubelet's config file. The --rotate-certificates flag is now deprecated, and will be removed in a future release. (#63912, @luxas)
  • Use DeleteOptions.PropagationPolicy instead of OrphanDependents in kubectl (#59851, @nilebox)
  • add block device support for azure disk (#63841, @andyzhangx)
  • Fix incorrectly propagated ResourceVersion in ListRequests returning 0 items. (#64150, @wojtek-t)
  • Changes ext3/ext4 volume creation to not reserve any portion of the volume for the root user. (#64102, @atombender)
  • Add CRD Versioning with NOP converter (#63830, @mbohlool)
  • adds a kubectl wait command (#64034, @deads2k)
  • "kubeadm init" now writes a structured and versioned kubelet ComponentConfiguration file to /var/lib/kubelet/config.yaml and an environment file with runtime flags (you can source this file in the systemd kubelet dropin) to /var/lib/kubelet/kubeadm-flags.env. (#63887, @luxas)
  • kubectl auth reconcile only works with rbac.v1 (#63967, @deads2k)
  • The dynamic Kubelet config feature will now update config in the event of a ConfigMap mutation, which reduces the chance for silent config skew. Only name, namespace, and kubeletConfigKey may now be set in Node.Spec.ConfigSource.ConfigMap. The least disruptive pattern for config management is still to create a new ConfigMap and incrementally roll out a new Node.Spec.ConfigSource. (#63221, @mtaufen)
  • Graduate CRI container log rotation to beta, and enable it by default. (#64046, @yujuhong)
  • APIServices with kube-like versions (e.g. v1, v2beta1, etc.) will be sorted appropriately within each group. (#64004, @mbohlool)
  • kubectl and client-go now detects duplicated name for user, cluster and context when loading kubeconfig and reports error (#60464, @roycaihw)
  • event object references with apiversion will now report an apiversion. (#63913, @deads2k)
  • Subresources for custom resources is now beta and enabled by default. With this, updates to the /status subresource will disallow updates to all fields other than .status (not just .spec and .metadata as before). Also, required can be used at the root of the CRD OpenAPI validation schema when the /status subresource is enabled. (#63598, @nikhita)
  • increase grpc client default response size (#63977, @runcom)
  • HTTP transport now uses context.Context to cancel dial operations. k8s.io/client-go/transport/Config struct has been updated to accept a function with a context.Context parameter. This is a breaking change if you use this field in your code. (#60012, @ash2k)
  • Adds a mechanism in vSphere Cloud Provider to get credentials from Kubernetes secrets (#63902, @abrarshivani)
  • kubeadm: A kubeadm config print-default command has now been added that you can use as a starting point when writing your own kubeadm configuration files (#63969, @luxas)
  • Update event-exporter to version v0.2.0 that supports old (gke_container/gce_instance) and new (k8s_container/k8s_node/k8s_pod) stackdriver resources. (#63918, @cezarygerard)
  • Cluster Autoscaler 1.2.2 (release notes: https://github.com/kubernetes/autoscaler/releases/tag/cluster-autoscaler-1.2.2) (#63974, @aleksandra-malinowska)
  • Update kubeadm's minimum supported kubernetes in v1.11.x to 1.10 (#63920, @dixudx)
  • Add 'UpdateStrategyType' and 'RollingUpdateStrategy' to 'kubectl describe sts' command output. (#63844, @tossmilestone)
  • Remove UID mutation from request.context. (#63957, @hzxuzhonghu)
  • kubeadm has removed .Etcd.SelfHosting from its configuration API. It was never used in practice. (#63871, @luxas)
  • list/watch API requests with a fieldSelector that specifies metadata.name can now be authorized as requests for an individual named resource (#63469, @wojtek-t)
  • Add a way to pass extra arguments to etcd. (#63961, @mborsz)
  • minor fix for VolumeZoneChecker predicate, storageclass can be in annotation and spec. (#63749, @wenlxie)
  • vSphere Cloud Provider: add SAML token authentication support (#63824, @dougm)
  • adds the kubeadm upgrade diff command to show how static pod manifests will be changed by an upgrade. (#63930, @liztio)
  • Fix memory cgroup notifications, and reduce associated log spam. (#63220, @dashpole)
  • Adds a kubeadm config images pull command to pull container images used by kubeadm. (#63833, @chuckha)
  • Restores the pre-1.10 behavior of the openstack cloud provider which uses the instance name as the Kubernetes Node name. This requires instances be named with RFC-1123 compatible names. (#63903, @liggitt)
  • Added support for NFS relations on kubernetes-worker charm. (#63817, @hyperbolic2346)
  • Stop using InfluxDB as default cluster monitoring (#62328, @serathius)
    • InfluxDB cluster monitoring is deprecated and will be removed in v1.12
  • GCE: Fix to make the built-in kubernetes service properly point to the master's load balancer address in clusters that use multiple master VMs. (#63696, @grosskur)
  • Kubernetes cluster on GCE have crictl installed now. Users can use it to help debug their node. The documentation of crictl can be found https://github.com/kubernetes-incubator/cri-tools/blob/master/docs/crictl.md. (#63357, @Random-Liu)
  • The NodeRestriction admission plugin now prevents kubelets from modifying/removing taints applied to their Node API object. (#63167, @liggitt)
  • The status of dynamic Kubelet config is now reported via Node.Status.Config, rather than the KubeletConfigOk node condition. (#63314, @mtaufen)
  • kubeadm now checks that IPv4/IPv6 forwarding is enabled (#63872, @kad)
  • kubeadm will now deploy CoreDNS by default instead of KubeDNS (#63509, @detiber)
  • This PR will leverage subtests on the existing table tests for the scheduler units. (#63658, @xchapter7x)
    • Some refactoring of error/status messages and functions to align with new approach.
  • kubeadm upgrade now supports external etcd setups again (#63495, @detiber)
  • fix mount unmount failure for a Windows pod (#63272, @andyzhangx)
  • CRI: update documents for container logpath. The container log path has been changed from containername_attempt#.log to containername/attempt#.log (#62015, @feiskyer)
  • Create a new dryRun query parameter for mutating endpoints. If the parameter is set, then the query will be rejected, as the feature is not implemented yet. This will allow forward compatibility with future clients; otherwise, future clients talking with older apiservers might end up modifying a resource even if they include the dryRun query parameter. (#63557, @apelisse)
  • kubelet: fix hangs in updating Node status after network interruptions/changes between the kubelet and API server (#63492, @liggitt)
  • The PriorityClass API is promoted to scheduling.k8s.io/v1beta1 (#63100, @ravisantoshgudimetla)
  • Services can listen on same host ports on different interfaces with --nodeport-addresses specified (#62003, @m1093782566)
  • kubeadm will no longer generate an unused etcd CA and certificates when configured to use an external etcd cluster. (#63806, @detiber)
  • corrects a race condition in bootstrapping aggregated cluster roles in new HA clusters (#63761, @liggitt)
  • Adding initial Korean translation for kubectl (#62040, @ianychoi)
  • Report node DNS info with --node-ip flag (#63170, @micahhausler)
  • The old dynamic client has been replaced by a new one. The previous dynamic client will exist for one release in client-go/deprecated-dynamic. Switch as soon as possible. (#63446, @deads2k)
  • CustomResourceDefinitions Status subresource now supports GET and PATCH (#63619, @roycaihw)
  • Re-enable nodeipam controller for external clouds. (#63049, @andrewsykim)
  • Removes a preflight check for kubeadm that validated custom kube-apiserver, kube-controller-manager and kube-scheduler arguments. (#63673, @chuckha)
  • Adds a list-images subcommand to kubeadm that lists required images for a kubeadm install. (#63450, @chuckha)
  • Apply pod name and namespace labels to pod cgroup in cAdvisor metrics (#63406, @derekwaynecarr)
  • try to read openstack auth config from client config and fall back to read from the environment variables if not available (#60200, @dixudx)
  • GC is now bound by QPS (it wasn't before) and so if you need more QPS to avoid ratelimiting GC, you'll have to set it. (#63657, @shyamjvs)
  • The Kubelet's deprecated --allow-privileged flag now defaults to true. This enables users to stop setting --allow-privileged in order to transition to PodSecurityPolicy. Previously, users had to continue setting --allow-privileged, because the default was false. (#63442, @mtaufen)
  • You must now specify Node.Spec.ConfigSource.ConfigMap.KubeletConfigKey when using dynamic Kubelet config to tell the Kubelet which key of the ConfigMap identifies its config file. (#59847, @mtaufen)
  • Kubernetes version command line parameter in kubeadm has been updated to drop an unnecessary redirection from ci/latest.txt to ci-cross/latest.txt. Users should know exactly where the builds are stored on Google Cloud storage buckets from now on. For example for 1.9 and 1.10, users can specify ci/latest-1.9 and ci/latest-1.10 as the CI build jobs what build images correctly updates those. The CI jobs for master update the ci-cross/latest location, so if you are looking for latest master builds, then the correct parameter to use would be ci-cross/latest. (#63504, @dims)
  • Search standard KubeConfig file locations when using kubeadm token without --kubeconfig. (#62850, @neolit123)
  • Include the list of security groups when failing with the errors that more then one is tagged (#58874, @sorenmat)
  • Allow "required" to be used at the CRD OpenAPI validation schema when the /status subresource is enabled. (#63533, @sttts)
  • When updating /status subresource of a custom resource, only the value at the .status subpath for the update is considered. (#63385, @CaoShuFeng)
  • Supported nodeSelector.matchFields (node's metadata.node) in scheduler. (#62453, @k82cn)
  • Do not check vmSetName when getting Azure node's IP (#63541, @feiskyer)
  • Fix stackdriver metrics for node memory using wrong metric type (#63535, @serathius)
  • [fluentd-gcp addon] Use the logging agent's node name as the metadata agent URL. (#63353, @bmoyles0117)
  • kubectl cp supports completion. (#60371, @superbrothers)
  • Azure VMSS: support VM names to contain the _ character (#63526, @djsly)
  • OpenStack built-in cloud provider is now deprecated. Please use the external cloud provider for OpenStack. (#63524, @dims)
  • the shortcuts which were moved server-side in at least 1.9 have been removed from being hardcoded in kubectl (#63507, @deads2k)
  • Fixes fake client generation for non-namespaced subresources (#60445, @jhorwit2)
  • kubectl delete with selection criteria defaults to ignoring not found errors (#63490, @deads2k)
  • Increase scheduler cache generation number monotonically in order to avoid collision and use of stale information in scheduler. (#63264, @bsalamat)
  • Fixes issue where subpath readOnly mounts failed (#63045, @msau42)
  • Update to use go1.10.2 (#63412, @praseodym)
  • kubectl create [secret | configmap] --from-file now works on Windows with fully-qualified paths (#63439, @liggitt)
  • kube-apiserver: the default --endpoint-reconciler-type is now lease. The master-count endpoint reconciler type is deprecated and will be removed in 1.13. (#63383, @liggitt)
  • owner references can be set during creation without deletion power (#63403, @deads2k)
  • Lays groundwork for OIDC distributed claims handling in the apiserver authentication token checker. (#63213, @filmil)
  • Use /usr/bin/env in all script shebangs to increase portability. (#62657, @matthyx)

Changelog since v1.11.0-alpha.1

Other notable changes

  • kubeadm upgrade plan now accepts a version which improves the UX nicer in air-gapped environments. (#63201, @chuckha)
  • kubectl now supports --field-selector for delete, label, and annotate (#60717, @liggitt)
  • kube-apiserver: --endpoint-reconciler-type now defaults to lease. The master-count reconciler is deprecated and will be removed in 1.13. (#58474, @rphillips)
  • OpenStack cloudprovider: Fix deletion of orphaned routes (#62729, @databus23)
  • Fix a bug that headless service without ports fails to have endpoint created. (#62497, @MrHohn)
  • Fix panic for attaching AzureDisk to vmss nodes (#63275, @feiskyer)
  • kubectl api-resources now supports filtering to resources supporting specific verbs, and can output fully qualified resource names suitable for combining with commands like kubectl get (#63254, @liggitt)
  • fix cephfs fuse mount bug when user is not admin (#61804, @zhangxiaoyu-zidif)
  • StorageObjectInUseProtection feature is GA. (#62870, @pospispa)
  • fixed spurious "unable to find api field" errors patching custom resources (#63146, @liggitt)
  • KUBE_API_VERSIONS is no longer respected. It was used for testing, but runtime-config is the proper flag to set. (#63165, @deads2k)
  • Added CheckNodePIDPressurePredicate to checks if a pod can be scheduled on (#60007, @k82cn)
    • a node reporting pid pressure condition.
  • Upgrade Azure Go SDK to stable version (v14.6.0) (#63063, @feiskyer)
  • kubeadm: prompt the user for confirmation when resetting a master node (#59115, @alexbrand)
  • add warnings on using pod-infra-container-image for remote container runtime (#62982, @dixudx)
  • Deprecate kubectl rolling-update (#61285, @soltysh)
  • client-go developers: the new dynamic client is easier to use and the old is deprecated, you must switch. (#62913, @deads2k)
  • Fix issue where on re-registration of device plugin, allocatable was not getting updated. This issue makes devices invisible to the Kubelet if device plugin restarts. Only work-around, if this fix is not there, is to restart the kubelet and then start device plugin. (#63118, @vikaschoudhary16)
  • Remove METADATA_AGENT_VERSION configuration option. (#63000, @kawych)
  • kubelets are no longer allowed to delete their own Node API object. Prior to 1.11, in rare circumstances related to cloudprovider node ID changes, kubelets would attempt to delete/recreate their Node object at startup. If a legacy kubelet encounters this situation, a cluster admin can remove the Node object: (#62818, @mikedanese) * kubectl delete node/<nodeName>
    • or grant self-deletion permission explicitly:
      • kubectl create clusterrole self-deleting-nodes --verb=delete --resource=nodes
      • kubectl create clusterrolebinding self-deleting-nodes --clusterrole=self-deleting-nodes --group=system:nodes
  • kubeadm creates kube-proxy with a toleration to run on all nodes, no matter the taint. (#62390, @discordianfish)
  • fix resultRun by resetting it to 0 on pod restart (#62853, @tony612)
  • Mount additional paths required for a working CA root, for setups where /etc/ssl/certs doesn't contains certificates but just symlink. (#59122, @klausenbusk)
  • Introduce truncating audit backend that can be enabled for existing backend to limit the size of individual audit events and batches of events. (#61711, @crassirostris)
  • kubeadm upgrade no longer races leading to unexpected upgrade behavior on pod restarts (#62655, @stealthybox)
    • kubeadm upgrade now successfully upgrades etcd and the controlplane to use TLS
    • kubeadm upgrade now supports external etcd setups
    • kubeadm upgrade can now rollback and restore etcd after an upgrade failure
  • Add --ipvs-exclude-cidrs flag to kube-proxy. (#62083, @rramkumar1)
  • Fix the liveness probe to use /bin/bash -c instead of /bin/bash c. (#63033, @bmoyles0117)
  • Added MatchFields to NodeSelectorTerm; in 1.11, it only support metadata.name. (#62002, @k82cn)
  • Fix scheduler informers to receive events for all the pods in the cluster. (#63003, @bsalamat)
  • removed unsafe double RLock in cpumanager (#62464, @choury)
  • Fix in vSphere Cloud Provider to handle upgrades from kubernetes version less than v1.9.4 to v1.9.4 and above. (#62919, @abrarshivani)
  • The --bootstrap-kubeconfig argument to Kubelet previously created the first bootstrap client credentials in the certificates directory as kubelet-client.key and kubelet-client.crt. Subsequent certificates created by cert rotation were created in a combined PEM file that was atomically rotated as kubelet-client-DATE.pem in that directory, which meant clients relying on the node.kubeconfig generated by bootstrapping would never use a rotated cert. The initial bootstrap certificate is now generated into the cert directory as a PEM file and symlinked to kubelet-client-current.pem so that the generated kubeconfig remains valid after rotation. (#62152, @smarterclayton)
  • stop kubelet to cloud provider integration potentially wedging kubelet sync loop (#62543, @ingvagabund)
  • Fix error where config map for Metadata Agent was not created by addon manager. (#62909, @kawych)
  • Fixes the kubernetes.default.svc loopback service resolution to use a loopback configuration. (#62649, @liggitt)
  • Code generated for CRDs now passes go vet. (#62412, @bhcleek)
  • fix permissions to allow statefulset scaling for admins, editors, and viewers (#62336, @deads2k)
  • Add support of standard LB to Azure vmss (#62707, @feiskyer)
  • GCE: Fix for internal load balancer management resulting in backend services with outdated instance group links. (#62885, @nicksardo)
  • The --experimental-qos-reserve kubelet flags is replaced by the alpha level --qos-reserved flag or QOSReserved field in the kubeletconfig and requires the QOSReserved feature gate to be enabled. (#62509, @sjenning)
  • Set pod status to "Running" if there is at least one container still reporting as "Running" status and others are "Completed". (#62642, @ceshihao)
  • Split PodPriority and PodPreemption feature gate (#62243, @resouer)
  • Add support to resize Portworx volumes. (#62308, @harsh-px)
