Changelog since v1.14.0-alpha.3

Action Required

  • Added cadvisor metric labels pod and container where pod_name and container_name are present to match instrumentation guidelines. (#69099, @ehashman)
    • Action required: any Prometheus queries that match pod_name and container_name labels (e.g. cadvisor or kubelet probe metrics) should be updated to use pod and container instead. pod_name and container_name labels will be present alongside pod and container labels for one transitional release and removed in the future.

  • [CRI] Add a new field called runtime_handler into PodSandbox and PodSandboxStatus to track the RuntimeClass information of a pod. (#73833, @haiyanmeng)
  • kubelet: OS and Arch information is now recorded in kubernetes.io/os and kubernetes.io/arch labels on Node objects. The previous labels (beta.kubernetes.io/os and beta.kubernetes.io/arch) are still recorded, but are deprecated and targeted for removal in 1.18. (#73333, @yujuhong)

    • The memory-cached discovery client is moved from k8s.io/client-go/discovery/cached to k8s.io/client-go/discovery/cached/memory.
  • kubelet now accepts pid=<number> in the --system-reserved and --kube-reserved options to ensure that the specified number of process IDs will be reserved for the system as a whole and for Kubernetes system daemons respectively. Please reference Kube Reserved and System Reserved in Reserve Compute Resources for System Daemons in the Kubernetes documentation for general discussion of resource reservation. To utilize this functionality, you must set the feature gate SupportNodePidsLimit=true (#73651, @RobertKrawitz)
  • The apiserver, including both the kube-apiserver and apiservers built with the generic apiserver library, will now return 413 RequestEntityTooLarge error if a json patch contains more than 10,000 operations. (#74000, @caesarxuchao)
  • kubeadm: allow the usage of --kubeconfig-dir and --config flags on kubeadm init (#73998, @yagonobre)

    • Custom apiservers built with the latest apiserver library will have the 100MB limit on the body of resource requests as well. The limit can be altered via ServerRunOptions.MaxRequestBodyBytes.
    • The body size limit does not apply to subresources like pods/proxy that proxy request content to another server.
  • Kustomize is developed in its own repo https://github.com/kubernetes-sigs/kustomize (#73033, @Liujingfang1)
    • This PR added a new subcommand kustomize in kubectl.
    • kubectl kustomize has the same effect as kustomize build
    • To build API resources from somedir with a kustomization.yaml file
    • kubectl kustomize
    • This command can be piped to apply or delete
    • kubectl kustomize | kubectl apply -f -
    • kubectl kustomize | kubectl delete -f -
  • kubeadm: all master components are now exclusively relying on the PriorityClassName pod spec for annotating them as cluster critical components. Since scheduler.alpha.kubernetes.io/critical-pod annotation is no longer supported by Kubernetes 1.14 this annotation is no longer added to master components. (#73857, @ereslibre)
  • Speedup kubectl by >10 when calling out to kube-apiserver for discovery information. (#73345, @sttts)
  • kubeadm no longer dumps backtrace if it fails to remove the running containers on reset. (#73951, @rosti)

      • A new k8s_external plugin that allows external zones to point to Kubernetes in-cluster services.
      • CoreDNS now checks if a zone transfer is allowed. Also allow a TTL of 0 to avoid caching in the cache plugin.
      • TTL is also applied to negative responses (NXDOMAIN, etc).

Changelog since v1.14.0-alpha.1

Action Required

  • Promote ValidateProxyRedirects to Beta, and enable by default. This feature restricts redirect following from the apiserver to same-host redirects. (#72552, @tallclair)
    • ACTION REQUIRED: If nodes are configured to respond to CRI streaming requests on a different host interface than what the apiserver makes requests on (only the case if not using the built-in dockershim & setting the kubelet flag --redirect-container-streaming=true), then these requests will be broken. In that case, the feature can be temporarily disabled until the node configuration is corrected. We suggest setting --redirect-container-streaming=false on the kubelet to avoid issues.

Other notable changes

  • Added alpha field storageVersionHash to the discovery document for each resource. Its value must be treated as opaque by clients. Only equality comparison on the value is valid. (#73191, @caesarxuchao)
  • Fix admission metrics in seconds. (#72343, @danielqsj)
    • Add metrics *_admission_latencies_milliseconds and *_admission_latencies_milliseconds_summary for backward compatible, but will be removed in a future release.
  • Pod eviction now honors graceful deletion by default if no delete options are provided in the eviction request (#72730, @liggitt)
  • Update to go1.11.5 (#73326, @ixdy)
  • Change proxy metrics to conform metrics guidelines. (#72334, @danielqsj)
    • The metrics sync_proxy_rules_latency_microseconds is deprecated, and will be removed in a future release, please convert to metricssync_proxy_rules_latency_seconds.
  • Add network stats for Windows nodes and pods. (#70121, @feiskyer)
  • kubeadm: When certificates are present joining a new control plane make sure that they match at least the required SANs (#73093, @ereslibre)
  • A new TaintNodesByCondition admission plugin taints newly created Node objects as "not ready", to fix a race condition that could cause pods to be scheduled on new nodes before their taints were updated to accurately reflect their reported conditions. This admission plugin is enabled by default if the TaintNodesByCondition feature is enabled. (#73097, @bsalamat)
  • kube-addon-manager was updated to v9.0, and now uses kubectl v1.13.2 and prunes workload resources via the apps/v1 API (#72978, @liggitt)
  • When a watch is closed by an HTTP2 load balancer and we are told to go away, skip printing the message to stderr by default. (#73277, @smarterclayton)
  • If you are running the cloud-controller-manager and you have the pvlabel.kubernetes.io alpha Initializer enabled, you must now enable PersistentVolume labeling using the PersistentVolumeLabel admission controller instead. You can do this by adding PersistentVolumeLabel in the --enable-admission-plugins kube-apiserver flag. (#73102, @andrewsykim)
  • The alpha Initializers feature, admissionregistration.k8s.io/v1alpha1 API version, Initializers admission plugin, and use of the metadata.initializers API field have been removed. Discontinue use of the alpha feature and delete any existing InitializerConfiguration API objects before upgrading. The metadata.initializers field will be removed in a future release. (#72972, @liggitt)
  • Scale max-inflight limits together with master VM sizes. (#73268, @wojtek-t)
  • kubectl supports copying files with wild card (#72641, @dixudx)
  • kubeadm: add back --cert-dir option for kubeadm init phase certs sa (#73239, @mattkelly)
  • Remove deprecated args '--show-all' (#69255, @Pingan2017)
  • As per deprecation policy in https://kubernetes.io/docs/reference/using-api/deprecation-policy/ (#73001, @shivnagarajan)
    • the taints "node.alpha.kubernetes.io/notReady" and "node.alpha.kubernetes.io/unreachable". are no
    • longer supported or adjusted. These uses should be replaced with "node.kubernetes.io/not-ready"
    • and "node.kubernetes.io/unreachable" respectively instead.
  • The /swagger.json and /swagger-2.0.0.pb-v1 schema documents, deprecated since v1.10, have been removed in favor of /openapi/v2 (#73148, @liggitt)
  • CoreDNS is only officially supported on Linux at this time. As such, when kubeadm is used to deploy this component into your kubernetes cluster, it will be restricted (using nodeSelectors) to run only on nodes with that operating system. This ensures that in clusters which include Windows nodes, the scheduler will not ever attempt to place CoreDNS pods on these machines, reducing setup latency and enhancing initial cluster stability. (#69940, @MarcPow)
  • kubeadm now attempts to detect an installed CRI by its usual domain socket, so that --cri-socket can be omitted from the command line if Docker is not used and there is a single CRI installed. (#69366, @rosti)
  • scheduler: makes pod less racing so as to be put back into activeQ properly (#73078, @Huang-Wei)
  • jsonpath expressions containing [start:end:step] slice are now evaluated correctly (#73149, @liggitt)
  • metadata.deletionTimestamp is no longer moved into the future when issuing repeated DELETE requests against a resource containing a finalizer. (#73138, @liggitt)
  • The "kubectl api-resources" command will no longer fail to display any resources on a single failure (#73035, @juanvallejo)
  • e2e tests that require SSH may be used against clusters that have nodes without external IP addresses by setting the environment variable KUBE_SSH_BASTION to the host:port of a machine that is allowed to SSH to those nodes. The same private key that the test would use is used for the bastion host. The test connects to the bastion and then tunnels another SSH connection to the node. (#72286, @smarterclayton)

Changelog since v1.13.0

Action Required

  • action required (#68753, @johnSchnake)
    • If you are running E2E tests which require SSH keys and you utilize environment variables to override their location, you may need to modify the environment variable set. On all providers the environment variable override can now be either an absolute path to the key or a relative path (relative to ~/.ssh). Specifically the changes are:
      • Created new GCE_SSH_KEY allowing specification of SSH keys for gce, gke, and kubemark.
      • AWS_SSH_KEY, previously assumed to be an absolute path can now be either relative or absolute
      • LOCAL_SSH_KEY (for local and vsphere providers) was previously assumed to be a filename relative to ~/.ssh but can now also be an absolute path
      • KUBE_SSH_KEY (for skeleton provider) was previously assumed to be a filename relative to ~/.ssh but can now also be an absolute path

Other notable changes

  • Connections from Pods to Services with 0 endpoints will now ICMP reject immediately, rather than blackhole and timeout. (#72534, @thockin)
  • Improve efficiency of preemption logic in clusters with many pending pods. (#72895, @bsalamat)

Previously, these would result in validation errors. (#72714, @mourya007)
  • Add metrics-port to kube-proxy cmd flags. (#72682, @whypro)
  • kubectl: fixed an issue with "too old resource version" errors continuously appearing when calling kubectl delete (#72825, @liggitt)

  • removes newline from json output for windows nodes #72657 (#72659, @jsturtevant)
  • The DenyEscalatingExec and DenyExecOnPrivileged admission plugins are deprecated and will be removed in v1.18. Use of PodSecurityPolicy or a custom admission plugin to limit creation of pods is recommended instead. (#72737, @liggitt)

  • kube-apiserver: When configuring integration with external KMS Providers, users can supply timeout value (i.e. how long should kube-apiserver wait before giving up on a call to KMS). (@immutableT ) (#72540, @immutableT)
  • The spec.readinessGates field is now dropped during creation of Pod objects unless the PodReadinessGates feature gate is enabled. (#72695, @rajathagasthya)
  • The spec.dataSource field is now dropped during creation of PersistentVolumeClaim objects unless the VolumeSnapshotDataSource feature gate is enabled. (#72666, @rajathagasthya)
  • Stop kubelet logging a warning to override hostname if there's no change detected. (#71560, @KashifSaadat)
  • client-go: fake clients now properly return NotFound errors when attempting to patch non-existent objects (#70886, @bouk)
  • kubectl: fixes a bug determining the correct namespace while running in a pod when the --context flag is explicitly specified, and the referenced context specifies the namespace default (#72529, @liggitt)
  • Fix scheduling starvation of pods in cluster with large number of unschedulable pods. (#72619, @everpeace)
  • If the AppArmor feature gate is disabled, AppArmor-specific annotations in pod and pod templates are dropped when the object is created, and during update of objects that do not already contain AppArmor annotations, rather than triggering a validation error. (#72655, @liggitt)
  • client-go: shortens refresh period for token files to 1 minute to ensure auto-rotated projected service account tokens are read frequently enough. (#72437, @liggitt)
  • Multiple tests which previously failed due to lack of external IP addresses defined on the nodes should now be passable. (#68792, @johnSchnake)
