v1.5.5

This release contains a fix for a PodSecurityPolicy vulnerability which allows users to make use of any existing PodSecurityPolicy object, even ones they are not authorized to use.

Other then that, this release contains no other changes from 1.5.4.

The vulnerability is tracked in http://issue.k8s.io/43459.

Who is affected?

Only Kubernetes 1.5.0-1.5.4 installations that do all of the following:

  • Enable the PodSecurityPolicy API (which is not enabled by default):
    • --runtime-config=extensions/v1beta1/podsecuritypolicy=true
  • Enable the PodSecurityPolicy admission plugin (which is not enabled by default):
    • --admission-control=...,PodSecurityPolicy,...
  • Use authorization to limit users' ability to use specific PodSecurityPolicy objects

What is the impact?

A user that is authorized to create pods can make use of any existing PodSecurityPolicy, even ones they are not authorized to use.

How can I mitigate this prior to installing 1.5.5?

  1. Export existing PodSecurityPolicy objects:
  • kubectl get podsecuritypolicies -o yaml > psp.yaml
  1. Review and delete any PodSecurityPolicy objects you do not want all pod-creating users to be able to use (NOTE: Privileged users that were making use of those policies will also lose access to those policies). For example:
  • kubectl delete podsecuritypolicies/my-privileged-policy
  1. After upgrading to 1.5.5, re-create the exported PodSecurityPolicy objects:
  • kubectl create -f psp.yaml

Features

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

  • API Machinery
  • Apps
    • [stable] When replica sets cannot create pods, they will now report detail via the API about the underlying reason (kubernetes/features#120)
    • [stable] kubectl apply is now able to delete resources you no longer need with --prune (kubernetes/features#128)
    • [beta] Deployments that cannot make progress in rolling out the newest version will now indicate via the API they are blocked (docs) (kubernetes/features#122)
    • [beta] StatefulSets allow workloads that require persistent identity or per-instance storage to be created and managed on Kubernetes. (docs) (kubernetes/features#137)
    • [beta] In order to preserve safety guarantees the cluster no longer force deletes pods on un-responsive nodes and users are now warned if they try to force delete pods via the CLI. (docs) (kubernetes/features#119)
  • Auth
  • AWS
  • Cluster Lifecycle
  • Cluster Ops
    • [alpha] Added ability to create/remove clusters w/highly available (replicated) masters on GCE using kube-up/kube-down scripts. (docs) (kubernetes/features#48)
  • Federation
  • Network
    • [stable] Services can reference another service by DNS name, rather than being hosted in pods (kubernetes/features#33)
    • [beta] Opt in source ip preservation for Services with Type NodePort or LoadBalancer (docs) (kubernetes/features#27)
    • [stable] Enable DNS Horizontal Autoscaling with beta ConfigMap parameters support (docs)

    • [alpha] Introducing the v1alpha1 CRI API to allow pluggable container runtimes; an experimental docker-CRI integration is ready for testing and feedback. (docs) (kubernetes/features#54)
    • [alpha] Kubelet launches container in a per pod cgroup hierarchy based on quality of service tier (kubernetes/features#126)
    • [beta] Kubelet integrates with memcg notification API to detect when a hard eviction threshold is crossed (kubernetes/features#125)
    • [beta] Introducing the beta version containerized node conformance test gcr.io/google_containers/node-test:0.2 for users to verify node setup. (docs) (kubernetes/features#84)
  • Scheduling
  • UI
  • Windows

Known Issues

Populated via v1.5.0 known issues / FAQ accumulator

  • CRI known issues and limitations
  • getDeviceNameFromMount() function doesn't return the volume path correctly when the volume path contains spaces #37712
  • Federation alpha features do not have feature gates defined and are hence enabled by default. This will be fixed in a future release. #38593
  • Federation control plane can be upgraded by updating the image fields in the Deployment specs of the control plane components. However, federation control plane upgrades were not tested in this release 38537

Notable Changes to Existing Behavior

  • Node controller no longer force-deletes pods from the api-server. (#35235, @foxish)

    • For StatefulSet (previously PetSet), this change means creation of replacement pods is blocked until old pods are definitely not running (indicated either by the kubelet returning from partitioned state, deletion of the Node object, deletion of the instance in the cloud provider, or force deletion of the pod from the api-server). This helps prevent "split brain" scenarios in clustered applications by ensuring that unreachable pods will not be presumed dead unless some "fencing" operation has provided one of the above indications.
    • For all other existing controllers except StatefulSet, this has no effect on the ability of the controller to replace pods because the controllers do not reuse pod names (they use generate-name).
    • User-written controllers that reuse names of pod objects should evaluate this change.
    • When deleting an object with kubectl delete ... --grace-period=0, the client will begin a graceful deletion and wait until the resource is fully deleted. To force deletion immediately, use the --force flag. This prevents users from accidentally allowing two Stateful Set pods to share the same persistent volume which could lead to data corruption #37263
  • Allow anonymous API server access, decorate authenticated users with system:authenticated group (#32386, @liggitt)

    • kube-apiserver learned the '--anonymous-auth' flag, which defaults to true. When enabled, requests to the secure port that are not rejected by other configured authentication methods are treated as anonymous requests, and given a username of 'system:anonymous' and a group of 'system:unauthenticated'.
    • Authenticated users are decorated with a 'system:authenticated' group.
    • IMPORTANT: See Action Required for important actions related to this change.
  • kubectl get -o jsonpath=... will now throw an error if the path is to a field not present in the json, even if the path is for a field valid for the type. This is a change from the pre-1.5 behavior, which would return the default value for some fields even if they were not present in the json. (#37991, @pwittrock)

  • The strategicmerge patchMergeKey for VolumeMounts was changed from "name" to "mountPath". This was necessary because the name field refers to the name of the Volume, and is not a unique key for the VolumeMount. Multiple VolumeMounts will have the same Volume name if mounting the same volume more than once. The "mountPath" is verified to be unique and can act as the mergekey. (#35071, @pwittrock)

Deprecations

  • extensions/v1beta1.Jobs is deprecated, use batch/v1.Job instead (#36355, @soltysh)
  • The kubelet --reconcile-cdir flag is deprecated because it has no function anymore. (#35523, @luxas)
  • Notice of deprecation for recycler #36760
  • The init-container (pod.beta.kubernetes.io/init-containers) annotations used to accept capitalized field names that could be accidentally generated by the k8s.io/kubernetes/pkg/api package. Using an upper case field name will now return an error and all users should use the versioned API types from pkg/api/v1 when serializing from Golang.

Action Required Before Upgrading

  • **Important Security-related changes before upgrading
    • You MUST set --anonymous-auth=false flag on your kube-apiserver unless you are a developer testing this feature and understand it. If you do not, you risk allowing unauthorized users to access your apiserver.
    • You MUST set --anonymous-auth=false flag on your federation apiserver unless you are a developer testing this feature and understand it. If you do not, you risk allowing unauthorized users to access your federation apiserver.
    • You do not need to adjust this flag on Kubelet: there was no authorization for the Kubelet APIs in 1.4.
  • batch/v2alpha1.ScheduledJob has been renamed, use batch/v2alpha1.CronJob instead (#36021, @soltysh)
  • PetSet has been renamed to StatefulSet. If you have existing PetSets, you must perform extra migration steps both before and after upgrading to convert them to StatefulSets. (docs) (#35663, @janetkuo)
  • If you are upgrading your Cluster Federation components from v1.4.x, please update your federation-apiserver and federation-controller-manager manifests to the new version (#30601, @madhusudancs)
  • The deprecated kubelet --configure-cbr0 flag has been removed, and with that the "classic" networking mode as well. If you depend on this mode, please investigate whether the other network plugins kubenet or cni meet your needs. (#34906, @luxas)
  • New client-go structure, refer to kubernetes/client-go for versioning policy (#34989, @caesarxuchao)
  • The deprecated kube-scheduler --bind-pods-qps and --bind-pods burst flags have been removed, use --kube-api-qps and --kube-api-burst instead (#34471, @timothysc)
  • If you used the PodDisruptionBudget feature in 1.4 (i.e. created PodDisruptionBudget objects), then BEFORE upgrading from 1.4 to 1.5, you must delete all PodDisruptionBudget objects (policy/v1alpha1/PodDisruptionBudget) that you have created. It is not possible to delete these objects after you upgrade, and their presence will prevent you from using the beta PodDisruptionBudget feature in 1.5 (which uses policy/v1beta1/PodDisruptionBudget). If you have already upgraded, you will need to downgrade the master to 1.4 to delete the policy/v1alpha1/PodDisruptionBudget objects.

External Dependency Version Information

Continuous integration builds have used the following versions of external dependencies, however, this is not a strong recommendation and users should consult an appropriate installation or upgrade guide before deciding what versions of etcd, docker or rkt to use.

  • Docker versions 1.10.3 - 1.12.3
    • Docker version 1.11.2 known issues
      • Kernel crash with Aufs storage driver on Debian Jessie (#27885 which can be identified by the node problem detector
      • Leaked File descriptors (#275)
      • Additional memory overhead per container (#21737
    • Docker version 1.12.1 has been validated through the Kubernetes docker automated validation framework as has Docker version 1.12.3
  • Docker 1.10.3 contains backports provided by RedHat for known issues
  • Docker versions as old as may 1.9.1 work with known issues but this is not guaranteed
  • rkt version 1.21.0
  • etcd version 2.2.1

Changelog since v1.5.0-beta.1

Other notable changes

  • Modify GCI mounter to enable NFSv3 (#36610, @jingxu97)
  • Third party resources are now deleted when a namespace is deleted. (#35947, @brendandburns)
  • kube-dns (#36775, @bowei)
    • Added --config-map and --config-map-namespace command line options.
    • If --config-map is set, kube-dns will load dynamic configuration from the config map
    • referenced by --config-map-namespace, --config-map. The config-map supports
    • the following properties: "federations".
    • --federations flag is now deprecated. Prefer to set federations via the config-map.
    • Federations can be configured by settings the "federations" field to the value currently
    • set in the command line.
    • Example:
    • kind: ConfigMap
    • apiVersion: v1
    • metadata:
    • name: kube-dns
    • namespace: kube-system
    • data:
    • federations: abc=def
  • azure: support multiple ipconfigs on a NIC (#36841, @colemickens)
  • Fix issue in converting AWS volume ID from mount paths (#36840, @jingxu97)
  • fix leaking memory backed volumes of terminated pods (#36779, @sjenning)
  • Default logging subsystem's resiliency was greatly improved, fluentd memory consumption and OOM error probability was reduced. (#37021, @Crassirostris)

Changelog since v1.5.0-alpha.2

Action Required

Other notable changes

  • Federation: allow specification of dns zone by ID (#36336, @justinsb)
  • K8s 1.5 keeps container-vm as the default node image on GCE for backwards compatibility reasons. Please beware that container-vm is officially deprecated (supported with security patches only) and you should replace it with GCI if at all possible. You can review the migration guide here for more detail: https://cloud.google.com/container-engine/docs/node-image-migration (#36822, @mtaufen)
  • Add a flag allowing contention profiling of the API server (#36756, @gmarek)

  • Add support for SourceIP preservation in Azure LBs (#36557, @brendandburns)
  • Fix fetching pids running in a cgroup, which caused problems with OOM score adjustments & setting the /system cgroup ("misc" in the summary API). (#36551, @timstclair)
  • federation: Adding support for DeleteOptions.OrphanDependents for federated replicasets and deployments. Setting it to false while deleting a federated replicaset or deployment also deletes the corresponding resource from all registered clusters. (#36476, @nikhiljindal)
  • kubectl: show node label if defined (#35901, @justinsb)
  • Migrates addons from RCs to Deployments (#36008, @MrHohn)
  • Avoid setting S_ISGID on files in volumes (#36386, @sjenning)

  • AWS: Support default value for ExternalHost (#33568, @justinsb)
  • HPA: Consider unready pods separately (#33593, @DirectXMan12)
  • Node Conformance Test: Containerize the node e2e test (#31093, @Random-Liu)
  • federation: Adding support for DeleteOptions.OrphanDependents for federated secrets. Setting it to false while deleting a federated secret also deletes the corresponding secrets from all registered clusters. (#36296, @nikhiljindal)
  • Deploy kube-dns with cluster-proportional-autoscaler (#33239, @MrHohn)
  • Adds support for StatefulSets in kubectl drain. (#35483, @ymqytw)
    • Switches to use the eviction sub-resource instead of deletion in kubectl drain, if server supports.
  • azure: load balancer preserves destination ip address (#36256, @colemickens)
  • LegacyHostIP will be deprecated in 1.7. (#36095, @caesarxuchao)

  • kubelet bootstrap: start hostNetwork pods before we have PodCIDR (#35526, @justinsb)
  • Enable HPA controller based on autoscaling/v1 api group (#36215, @piosz)
  • Remove unused WaitForDetach from Detacher interface and plugins (#35629, @kiall)
  • Initial work on running windows containers on Kubernetes (#31707, @alexbrand)
  • Per Volume Inode Accounting (#35132, @dashpole)
  • [AppArmor] Hold bad AppArmor pods in pending rather than rejecting (#35342, @timstclair)
  • Federation: separate notion of zone-name & dns-suffix (#35372, @justinsb)
  • In order to bypass graceful deletion of pods (to immediately remove the pod from the API) the user must now provide the --force flag in addition to --grace-period=0. This prevents users from accidentally force deleting pods without being aware of the consequences of force deletion. Force deleting pods for resources like StatefulSets can result in multiple pods with the same name having running processes in the cluster, which may lead to data corruption or data inconsistency when using shared storage or common API endpoints. (#35484, @smarterclayton)
  • NPD: Add e2e test for NPD v0.2. (#35740, @Random-Liu)
  • DELETE requests can now pass in their DeleteOptions as a query parameter or a body parameter, rather than just as a body parameter. (#35806, @bdbauer)
  • make using service account credentials from controllers optional (#35970, @deads2k)
  • AWS: strong-typing for k8s vs aws volume ids (#35883, @justinsb)
  • Controller changes for perma failed deployments (#35691, @kargakis)
  • Proxy min sync period (#35334, @timothysc)
  • Federated ConfigMap controller (#35635, @mwielgus)
  • have basic kubectl crud agnostic of registered types (#36085, @deads2k)
  • Fix how we iterate over active jobs when removing them for Replace policy (#36161, @soltysh)
  • Adds TCPCloseWaitTimeout option to kube-proxy for sysctl nf_conntrack_tcp_timeout_time_wait (#35919, @bowei)
  • Pods that are terminating due to eviction by the nodecontroller (typically due to unresponsive kubelet, or network partition) now surface in kubectl get output (#36017, @foxish)
    • as being in state "Unknown", along with a longer description in kubectl describe output.
  • The hostname of the node (as autodetected by the kubelet, specified via --hostname-override, or determined by the cloudprovider) is now recorded as an address of type "Hostname" in the status of the Node API object. The hostname is expected to be resolveable from the apiserver. (#25532, @mkulke)
  • [Kubelet] Add alpha support for --cgroups-per-qos using the configured --cgroup-driver. Disabled by default. (#31546, @derekwaynecarr)
  • Move Statefulset (previously PetSet) to v1beta1 (#35731, @janetkuo)
  • The error handling behavior of pkg/client/restclient.Result has changed. Calls to Result.Raw() will no longer parse the body, although they will still return errors that react to pkg/api/errors.Is*() as in previous releases. Callers of Get() and Into() will continue to receive errors that are parsed from the body if the kind and apiVersion of the body match the Status object. (#36001, @smarterclayton)
    • This more closely aligns rest client as a generic RESTful client, while preserving the special Kube API extended error handling for the Get and Into methods (which most Kube clients use).
  • Making the pod.alpha.kubernetes.io/initialized annotation optional in PetSet pods (#35739, @foxish)
  • AWS: recognize us-east-2 region (#35013, @justinsb)

  • Correct the article in generated documents (#32557, @asalkeld)
  • Update PodAntiAffinity to ignore calls to subresources (#35608, @soltysh)
  • The apiserver can now select which type of kubelet-reported address to use for apiserver->node communications, using the --kubelet-preferred-address-types flag. (#35497, @liggitt)
  • update list of vailable resources (#32687, @jouve)
  • Remove stale volumes if endpoint/svc creation fails. (#35285, @humblec)
  • add kubectl cp (#34914, @brendandburns)

Changelog since v1.4.0-alpha.3

Experimental Features

Action Required

  • kube-apiserver learned the '--anonymous-auth' flag, which defaults to true. When enabled, requests to the secure port that are not rejected by other configured authentication methods are treated as anonymous requests, and given a username of 'system:anonymous' and a group of 'system:unauthenticated'. (#32386, @liggitt)
    • Authenticated users are decorated with a 'system:authenticated' group.
    • NOTE: anonymous access is enabled by default. If you rely on authentication alone to authorize access, change to use an authorization mode other than AlwaysAllow, or or set '--anonymous-auth=false'.
  • The NamespaceExists and NamespaceAutoProvision admission controllers have been removed. (#31250, @derekwaynecarr)
    • All cluster operators should use NamespaceLifecycle.
  • Federation binaries and their corresponding docker images - federation-apiserver and federation-controller-manager are now folded in to the hyperkube binary. If you were using one of these binaries or docker images, please switch to using the hyperkube version. Please refer to the federation manifests - federation/manifests/federation-apiserver.yaml and federation/manifests/federation-controller-manager-deployment.yaml for examples. (#29929, @madhusudancs)

Other notable changes

  • The kube-apiserver --service-account-key-file option can be specified multiple times, or can point to a file containing multiple keys, to enable rotation of signing keys. (#34029, @liggitt)
  • The apiserver now uses addresses reported by the kubelet in the Node object's status for apiserver->kubelet communications, rather than the name of the Node object. The address type used defaults to InternalIP, ExternalIP, and LegacyHostIP address types, in that order. (#33718, @justinsb)

  • The implicit registration of Prometheus metrics for workqueue has been removed, and a plug-able interface was added. If you were using workqueue in your own binaries and want these metrics, add the following to your imports in the main package: "k8s.io/pkg/util/workqueue/prometheus". (#33792, @caesarxuchao)
  • Add kubectl --node-port option for specifying the service nodeport (#33319, @juanvallejo)
