Major Themes

  • Simplified User Experience
    • Easier to get a cluster up and running (eg: kubeadm, intra-cluster bootstrapping)
    • Easier to understand a cluster (eg: API audit logs, server-based API defaults)
  • Stateful Appplication Support
    • Enhanced persistence capabilities (eg: StorageClasses, new volume plugins)
    • New resources and scheduler features (eg: ScheduledJob resource, pod/node affinity/anti-affinity)
  • Cluster Federation
    • Global Multi-cluster HTTP(S) Ingress across GCE and GKE clusters.
    • Expanded support for federated hybrid-cloud resources including ReplicaSets, Secrets, Namespaces and Events.
  • Security
    • Increased pod-level security granularity (eg: Container Image Policies, AppArmor and sysctl support)
    • Increased cluster-level security granularity (eg: Access Review API)

Features

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

  • API Machinery
    • [alpha] Generate audit logs for every request user performs against secured API server endpoint. (docs) (kubernetes/features#22)
    • [beta] kube-apiserver now publishes a swagger 2.0 spec in addition to a swagger 1.2 spec (kubernetes/features#53)
    • [beta] Server-side garbage collection is enabled by default. See user-guide
  • Apps
    • [alpha] Introducing 'ScheduledJobs', which allow running time based Jobs, namely once at a specified time or repeatedly at specified point in time. (docs) (kubernetes/features#19)
  • Auth
    • [alpha] Container Image Policy allows an access controller to determine whether a pod may be scheduled based on a policy (docs) (kubernetes/features#59)
    • [alpha] Access Review APIs expose authorization engine to external inquiries for delegation, inspection, and debugging (docs) (kubernetes/features#37)
  • Cluster Lifecycle
    • [alpha] Ensure critical cluster infrastructure pods (Heapster, DNS, etc.) can schedule by evicting regular pods when necessary to make the critical pods schedule. (docs) (kubernetes/features#62)
    • [alpha] Simplifies bootstrapping of TLS secured communication between the API server and kubelet. (docs) (kubernetes/features#43)
    • [alpha] The kubeadm tool makes it much easier to bootstrap Kubernetes. (docs) (kubernetes/features#11)
  • Federation
    • [alpha] Creating a Federated Ingress is as simple as submitting an Ingress creation request to the Federation API Server. The Federation control system then creates and maintains a single global virtual IP to load balance incoming HTTP(S) traffic across some or all the registered clusters, across all regions. Google's GCE L7 LoadBalancer is the first supported implementation, and is available in this release. (docs) (kubernetes/features#82)
    • [beta] Federated Replica Sets create and maintain matching Replica Sets in some or all clusters in a federation, with the desired replica count distributed equally or according to specified per-cluster weights. (docs) (kubernetes/features#46)
    • [beta] Federated Secrets are created and kept consistent across all clusters in a federation. (docs) (kubernetes/features#68)
    • [beta] Federation API server gained support for events and many federation controllers now report important events. (docs) (kubernetes/features#70)
    • [alpha] Creating a Federated Namespace causes matching Namespaces to be created and maintained in all the clusters registered with that federation. (docs) (kubernetes/features#69)
    • [alpha] ingress has alpha support for a single master multi zone cluster (docs) (kubernetes/features#52)
  • Network
  • Node
  • Scheduling
    • [alpha] Allows pods to require or prohibit (or prefer or prefer not) co-scheduling on the same node (or zone or other topology domain) as another set of pods. (docs (kubernetes/features#51)
  • Storage
  • UI
    • [stable] Kubernetes Dashboard UI - a great looking Kubernetes Dashboard UI with 90% CLI parity for at-a-glance management. docs
    • [stable] kubectl no longer applies defaults before sending objects to the server in create and update requests, allowing the server to apply the defaults. (kubernetes/features#55)

Known Issues

  • Completed pods lose logs across node upgrade (#32324)
  • Pods are deleted across node upgrade (#32323)
  • Secure master -> node communication (#11816)
  • upgrading master doesn't upgrade kubectl (#32538)
  • Specific error message on failed rolling update issued by older kubectl against 1.4 master (#32751)
  • bump master cidr range from /30 to /29 (#32886)
  • non-hostNetwork daemonsets will almost always have a pod that fails to schedule (#32900)
  • Service loadBalancerSourceRanges doesn't respect updates (#33033)
  • disallow user to update loadbalancerSourceRanges (#33346)

Notable Changes to Existing Behavior

Deployments

  • ReplicaSets of paused Deployments are now scaled while the Deployment is paused. This is retroactive to existing Deployments.
  • When scaling a Deployment during a rollout, the ReplicaSets of all Deployments are now scaled proportionally based on the number of replicas they each have instead of only scaling the newest ReplicaSet.

kubectl rolling-update: < v1.4.0 client vs >=v1.4.0 cluster

Old version kubectl's rolling-update command is compatible with Kubernetes 1.4 and higher only if you specify a new replication controller name. You will need to update to kubectl 1.4 or higher to use the rolling update command against a 1.4 cluster if you want to keep the original name, or you'll have to do two rolling updates.

If you do happen to use old version kubectl's rolling update against a 1.4 cluster, it will fail, usually with an error message that will direct you here. If you saw that error, then don't worry, the operation succeeded except for the part where the new replication controller is renamed back to the old name. You can just do another rolling update using kubectl 1.4 or higher to change the name back: look for a replication controller that has the original name plus a random suffix.

Unfortunately, there is a much rarer second possible failure mode: the replication controller gets renamed to the old name, but there is a duplicated set of pods in the cluster. kubectl will not report an error since it thinks its job is done.

If this happens to you, you can wait at most 10 minutes for the replication controller to start a resync, the extra pods will then be deleted. Or, you can manually trigger a resync by change the replicas in the spec of the replication controller.

kubectl delete: < v1.4.0 client vs >=v1.4.0 cluster

If you use an old version kubectl to delete a replication controller or replicaset, then after the delete command has returned, the replication controller or the replicaset will continue to exist in the key-value store for a short period of time (<1s). You probably will not notice any difference if you use kubectl manually, but you might notice it if you are using kubectl in a script.

DELETE operation in REST API

  • Replication controller & Replicaset: the DELETE request of a replication controller or a replicaset becomes asynchronous by default. The object will continue to exist in the key-value store for some time. The API server will set its metadata.deletionTimestamp, add the "orphan" finalizer to its metadata.finalizers. The object will be deleted from the key-value store after the garbage collector orphans its dependents. Please refer to this user-guide for more information regarding the garbage collection.

  • Other objects: no changes unless you explicitly request orphaning.

Action Required Before Upgrading

  • If you are using Kubernetes to manage docker containers, please be aware Kubernetes has been validated to work with docker 1.9.1, docker 1.11.2 (#23397), and docker 1.12.0 (#28698)
  • If you upgrade your apiserver to 1.4.x but leave your kubelets at 1.3.x, they will not report init container status, but init containers will work properly. Upgrading kubelets to 1.4.x fixes this.
  • The NamespaceExists and NamespaceAutoProvision admission controllers have been removed, use the NamespaceLifecycle admission controller instead (#31250, @derekwaynecarr)
  • If upgrading Cluster Federation components from 1.3.x, the federation-apiserver and federation-controller-manager binaries have been folded into hyperkube. Please switch to using that instead. (#29929, @madhusudancs)
  • If you are using the PodSecurityPolicy feature (eg: kubectl get podsecuritypolicy does not error, and returns one or more objects), be aware that init containers have moved from alpha to beta. If there are any pods with the key pods.beta.kubernetes.io/init-containers, then that pod may not have been filtered by the PodSecurityPolicy. You should find such pods and either delete them or audit them to ensure they do not use features that you intend to be blocked by PodSecurityPolicy. (#31026, @erictune)
  • If upgrading Cluster Federation components from 1.3.x, please ensure your cluster name is a valid DNS label (#30956, @nikhiljindal)
  • kubelet's --config flag has been deprecated, use --pod-manifest-path instead (#29999, @mtaufen)
  • If upgrading Cluster Federation components from 1.3.x, be aware the federation-controller-manager now looks for a different secret name. Run the following to migrate (#28938, @madhusudancs)
kubectl --namespace=federation get secret federation-apiserver-secret -o json | sed 's/federation-apiserver-secret/federation-apiserver-kubeconfig/g' | kubectl create -f -
# optionally, remove the old secret
kubectl delete secret --namespace=federation federation-apiserver-secret
  • Kubernetes components no longer handle panics, and instead actively crash. All Kubernetes components should be run by something that actively restarts them. This is true of the default setups, but those with custom environments may need to double-check (#28800, @lavalamp)
  • kubelet now defaults to --cloud-provider=auto-detect, use --cloud-provider='' to preserve previous default of no cloud provider (#28258, @vishh)

  • Handle overlapping deployments gracefully (#30730, @janetkuo)
  • Remove environment variables and internal Kubernetes Docker labels from cAdvisor Prometheus metric labels. (#31064, @grobie)
    • Old behavior:
      • environment variables explicitly whitelisted via --docker-env-metadata-whitelist were exported as container_env_*=*. Default is zero so by default non were exported
      • all docker labels were exported as container_label_*=*

Changelog since v1.4.0-alpha.2

Action Required

  • Moved init-container feature from alpha to beta. (#31026, @erictune)
    • Security Action Required:
    • This only applies to you if you use the PodSecurityPolicy feature. You are using that feature if kubectl get podsecuritypolicy returns one or more objects. If it returns an error, you are not using it.
    • If there are any pods with the key pods.beta.kubernetes.io/init-containers, then that pod may not have been filtered by the PodSecurityPolicy. You should find such pods and either delete them or audit them to ensure they do not use features that you intend to be blocked by PodSecurityPolicy.
    • Explanation of Feature
    • In 1.3, an init container is specified with this annotation key
    • on the pod or pod template: pods.alpha.kubernetes.io/init-containers.
    • In 1.4, either that key or this key: pods.beta.kubernetes.io/init-containers,
    • can be used.
    • When you GET an object, you will see both annotation keys with the same values.
    • You can safely roll back from 1.4 to 1.3, and things with init-containers
    • will still work (pods, deployments, etc).
    • If you are running 1.3, only use the alpha annotation, or it may be lost when
    • rolling forward.
    • The status has moved from annotation key
    • pods.beta.kubernetes.io/init-container-statuses to
    • pods.beta.kubernetes.io/init-container-statuses.
    • Any code that inspects this annotation should be changed to use the new key.
    • State of Initialization will continue to be reported in both pods.alpha.kubernetes.io/initialized
    • and in podStatus.conditions.{status: "True", type: Initialized}
  • Action required: federation-only: Please update your cluster name to be a valid DNS label. (#30956, @nikhiljindal)
    • Updating federation.v1beta1.Cluster API to disallow subdomains as valid cluster names. Only DNS labels are allowed as valid cluster names now.
  • [Kubelet] Rename --config to --pod-manifest-path. --config is deprecated. (#29999, @mtaufen)

Other notable changes

  • rkt: Improve support for privileged pod (pod whose all containers are privileged) (#31286, @yifan-gu)
  • The pod annotation security.alpha.kubernetes.io/sysctls now allows customization of namespaced and well isolated kernel parameters (sysctls), starting with kernel.shm_rmid_forced, net.ipv4.ip_local_port_range and net.ipv4.tcp_syncookies for Kubernetes 1.4. (#27180, @sttts)
    • The pod annotation security.alpha.kubernetes.io/unsafe-sysctls allows customization of namespaced sysctls where isolation is unclear. Unsafe sysctls must be enabled at-your-own-risk on the kubelet with the --experimental-allowed-unsafe-sysctls flag. Future versions will improve on resource isolation and more sysctls will be considered safe.
  • Increase request timeout based on termination grace period (#31275, @dims)
  • Fixed two issues of kubectl bash completion. (#31135, @xingzhou)
  • Reduced size of fluentd images. (#31239, @aledbf)

  • Let Services preserve client IPs and not double-hop from external LBs (alpha) (#29409, @girishkalele)
  • [Kubelet] Optionally consume configuration from named config maps (#30090, @mtaufen)
  • [GarbageCollector] Allow per-resource default garbage collection behavior (#30838, @caesarxuchao)
  • Action required: If you have a running federation control plane, you will have to ensure that for all federation resources, the corresponding namespace exists in federation control plane. (#31139, @nikhiljindal)
    • federation-apiserver now supports NamespaceLifecycle admission control, which is enabled by default. Set the --admission-control flag on the server to change that.
  • Configure webhook (#30923, @Q-Lee)
  • Federated Ingress Controller (#30419, @quinton-hoole)
  • Federation replicaset controller (#29741, @jianhuiz)

  • kube-up: Allow IP restrictions for SSH and HTTPS API access on AWS. (#27061, @Naddiseo)
  • Add readyReplicas to replica sets (#29481, @kargakis)
  • The implicit registration of Prometheus metrics for request count and latency have been removed, and a plug-able interface was added.

  • Implement TLS bootstrap for kubelet using --experimental-bootstrap-kubeconfig (2nd take) (#30922, @yifan-gu)
  • rkt: Support subPath volume mounts feature (#30934, @yifan-gu)
  • Return container command exit codes in kubectl run/exec (#26541, @sttts)
  • Fix kubectl describe to display a container's resource limit env vars as node allocatable when the limits are not set (#29849, @aveshagarwal)
  • The valueFrom.fieldRef.name field on environment variables in pods and objects with pod templates now allows two additional fields to be used: (#27880, @smarterclayton) * spec.nodeName will return the name of the node this pod is running on * spec.serviceAccountName will return the name of the service account this pod is running under
  • Adding ImagePolicyWebhook admission controller. (#30631, @ecordell)
  • Validate involvedObject.Namespace matches event.Namespace (#30533, @liggitt)
  • allow group impersonation (#30803, @deads2k)
  • Always return command output for exec probes and kubelet RunInContainer (#30731, @ncdc)
  • Enable the garbage collector by default (#30480, @caesarxuchao)
  • use valid_resources to replace kubectl.PossibleResourceTypes (#30955, @lojies)
  • oidc auth provider: don't trim issuer URL (#30944, @ericchiang)
  • Add a short -n for kubectl --namespace (#30630, @silasbw)
  • Federated secret controller (#30669, @kshafiee)
  • Add Events for operation_executor to show status of mounts, failed/successful to show in describe events (#27778, @screeley44)
  • Alpha support for OpenAPI (aka. Swagger 2.0) specification served on /swagger.json (enabled by default) (#30233, @mbohlool)
  • Disable linux/ppc64le compilation by default (#30659, @ixdy)
  • Implement dynamic provisioning (beta) of PersistentVolumes via StorageClass (#29006, @jsafrane)
  • Allow setting permission mode bits on secrets, configmaps and downwardAPI files (#28936, @rata)
  • Skip safe to detach check if node API object no longer exists (#30737, @saad-ali)
  • The Kubelet now supports the --require-kubeconfig option which reads all client config from the provided --kubeconfig file and will cause the Kubelet to exit with error code 1 on error. It also forces the Kubelet to use the server URL from the kubeconfig file rather than the --api-servers flag. Without this flag set, a failure to read the kubeconfig file would only result in a warning message. (#30798, @smarterclayton)
    • In a future release, the value of this flag will be defaulted to true.
  • Adding container image verification webhook API. (#30241, @Q-Lee)

Changelog since v1.3.0

Experimental Features

  • An alpha implementation of the TLS bootstrap API described in docs/proposals/kubelet-tls-bootstrap.md. (#25562, @gtank)

Action Required

  • [kubelet] Allow opting out of automatic cloud provider detection in kubelet. By default kubelet will auto-detect cloud providers (#28258, @vishh)
  • If you use one of the kube-dns replication controller manifest in cluster/saltbase/salt/kube-dns, i.e. cluster/saltbase/salt/kube-dns/{skydns-rc.yaml.base,skydns-rc.yaml.in}, either substitute one of __PILLAR__FEDERATIONS__DOMAIN__MAP__ or {{ pillar['federations_domain_map'] }} with the corresponding federation name to domain name value or remove them if you do not support cluster federation at this time. If you plan to substitute the parameter with its value, here is an example for {{ pillar['federations_domain_map'] }} (#28132, @madhusudancs)
    • pillar['federations_domain_map'] = "- --federations=myfederation=federation.test"
    • where myfederation is the name of the federation and federation.test is the domain name registered for the federation.
  • Proportionally scale paused and rolling deployments (#20273, @kargakis)
