# 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`
2. 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`
3. After upgrading to 1.5.5, re-create the exported PodSecurityPolicy objects:
  * `kubectl create -f psp.yaml`

## Changelog since v1.5.0

### Other notable changes

* Changes the default value of the "anonymous-auth" flag to a safer default value of false. This affects kube apiserver and federation apiserver. See https://groups.google.com/forum/#!topic/kubernetes-announce/iclRj-6Nfsg for more details.  ([#38708](https://github.com/kubernetes/kubernetes/pull/38708), [@erictune](https://github.com/erictune))
* Fixes issue where if the audit log is enabled and anonymous authentication is disabled, then an unauthenticated user request will cause a panic and crash the `kube-apiserver`. ([#38717](https://github.com/kubernetes/kubernetes/pull/38717), [@deads2k](https://github.com/deads2k))

## Known Issues for v1.5.1

- `hack/local-up-cluster.sh` script times out waiting for apiserver to answer, see [#38847](https://github.com/kubernetes/kubernetes/issues/38847).
  To workaround this, modify the script to pass `--anonymous-auth=true` to `sudo -E "${GO_OUT}/hyperkube" apiserver ...` when starting `kube-apiserver`.

## Features

Features for this release were tracked via the use of the [kubernetes/features](https://github.com/kubernetes/features) issues repo.  Each Feature issue is owned by a Special Interest Group from [kubernetes/community](https://github.com/kubernetes/community)

- **API Machinery**
  - [beta] `kube-apiserver` support for the OpenAPI spec is moving from alpha to beta. The first [non-go client](https://github.com/kubernetes-incubator/client-python) is based on it ([kubernetes/features#53](https://github.com/kubernetes/enhancements/issues/53))
- **Apps**
  - [stable] When replica sets cannot create pods, they will now report detail via the API about the underlying reason ([kubernetes/features#120](https://github.com/kubernetes/enhancements/issues/120))
  - [stable] `kubectl apply` is now able to delete resources you no longer need with `--prune` ([kubernetes/features#128](https://github.com/kubernetes/enhancements/issues/128))
  - [beta] Deployments that cannot make progress in rolling out the newest version will now indicate via the API they are blocked ([docs](http://kubernetes.io/docs/user-guide/deployments/#failed-deployment)) ([kubernetes/features#122](https://github.com/kubernetes/enhancements/issues/122))
  - [beta] StatefulSets allow workloads that require persistent identity or per-instance storage to be created and managed on Kubernetes. ([docs](http://kubernetes.io/docs/concepts/abstractions/controllers/statefulsets/)) ([kubernetes/features#137](https://github.com/kubernetes/enhancements/issues/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](http://kubernetes.io/docs/tasks/manage-stateful-set/scale-stateful-set/)) ([kubernetes/features#119](https://github.com/kubernetes/enhancements/issues/119))
- **Auth**
  - [alpha] Further polishing of the Role-based access control alpha API including a default set of cluster roles. ([docs](http://kubernetes.io/docs/admin/authorization/)) ([kubernetes/features#2](https://github.com/kubernetes/enhancements/issues/2))
  - [beta] Added ability to authenticate/authorize access to the Kubelet API ([docs](http://kubernetes.io/docs/admin/kubelet-authentication-authorization/)) ([kubernetes/features#89](https://github.com/kubernetes/enhancements/issues/89))
- **AWS**
  - [stable] Roles should appear in kubectl get nodes ([kubernetes/features#113](https://github.com/kubernetes/enhancements/issues/113))
- **Cluster Lifecycle**
  - [alpha] Improved UX and usability for the kubeadm binary that makes it easy to get a new cluster running. ([docs](http://kubernetes.io/docs/getting-started-guides/kubeadm/)) ([changelog](https://github.com/kubernetes/kubeadm/blob/master/CHANGELOG.md)) ([kubernetes/features#11](https://github.com/kubernetes/enhancements/issues/11))
- **Cluster Ops**

## Known Issues

Populated via [v1.5.0 known issues / FAQ accumulator](https://github.com/kubernetes/kubernetes/issues/37134)

* CRI [known issues and
  limitations](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-node/container-runtime-interface.md#kubernetes-v15-release-cri-v1alpha1)
* getDeviceNameFromMount() function doesn't return the volume path correctly when the volume path contains spaces [#37712](https://github.com/kubernetes/kubernetes/issues/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](https://github.com/kubernetes/kubernetes/issues/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](https://github.com/kubernetes/kubernetes/issues/38537)

## Notable Changes to Existing Behavior

* Node controller no longer force-deletes pods from the api-server. ([#35235](https://github.com/kubernetes/kubernetes/pull/35235), [@foxish](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/37263)


* Allow anonymous API server access, decorate authenticated users with system:authenticated group ([#32386](https://github.com/kubernetes/kubernetes/pull/32386), [@liggitt](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/37991), [@pwittrock](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/35071), [@pwittrock](https://github.com/pwittrock))

## Deprecations

* extensions/v1beta1.Jobs is deprecated, use batch/v1.Job instead ([#36355](https://github.com/kubernetes/kubernetes/pull/36355), [@soltysh](https://github.com/soltysh))
* The kubelet --reconcile-cdir flag is deprecated because it has no function anymore. ([#35523](https://github.com/kubernetes/kubernetes/pull/35523), [@luxas](https://github.com/luxas))
* Notice of deprecation for recycler [#36760](https://github.com/kubernetes/kubernetes/pull/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](https://github.com/kubernetes/kubernetes/pull/36021), [@soltysh](https://github.com/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](http://kubernetes.io/docs/tasks/manage-stateful-set/upgrade-pet-set-to-stateful-set/)) ([#35663](https://github.com/kubernetes/kubernetes/pull/35663), [@janetkuo](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/30601), [@madhusudancs](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/34906), [@luxas](https://github.com/luxas))
* New client-go structure, refer to kubernetes/client-go for versioning policy ([#34989](https://github.com/kubernetes/kubernetes/pull/34989), [@caesarxuchao](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/34471), [@timothysc](https://github.com/timothysc))
* If you used the [PodDisruptionBudget](http://kubernetes.io/docs/admin/disruptions/) 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.

* rkt version 1.21.0
  * known issues with the rkt runtime are [listed here](http://kubernetes.io/docs/getting-started-guides/rkt/notes/)
* etcd version 2.2.1
  * etcd version 3.0.14 [has also been validated](https://k8s-gubernator.appspot.com/builds/kubernetes-jenkins/logs/ci-kubernetes-e2e-gce-etcd3/) but does require [specific configuration steps](https://coreos.com/blog/migrating-applications-etcd-v3.html)

## Changelog since v1.5.0-beta.1

### Other notable changes

* Modify GCI mounter to enable NFSv3 ([#36610](https://github.com/kubernetes/kubernetes/pull/36610), [@jingxu97](https://github.com/jingxu97))
* Third party resources are now deleted when a namespace is deleted. ([#35947](https://github.com/kubernetes/kubernetes/pull/35947), [@brendandburns](https://github.com/brendandburns))
* kube-dns ([#36775](https://github.com/kubernetes/kubernetes/pull/36775), [@bowei](https://github.com/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:
      ```yaml
      kind: ConfigMap
      apiVersion: v1
      metadata:
        name: kube-dns
        namespace: kube-system
      data:
        federations: abc=def
      ```
* azure: support multiple ipconfigs on a NIC ([#36841](https://github.com/kubernetes/kubernetes/pull/36841), [@colemickens](https://github.com/colemickens))
* Fix issue in converting AWS volume ID from mount paths ([#36840](https://github.com/kubernetes/kubernetes/pull/36840), [@jingxu97](https://github.com/jingxu97))
* fix leaking memory backed volumes of terminated pods ([#36779](https://github.com/kubernetes/kubernetes/pull/36779), [@sjenning](https://github.com/sjenning))
* Default logging subsystem's resiliency was greatly improved, fluentd memory consumption and OOM error probability was reduced. ([#37021](https://github.com/kubernetes/kubernetes/pull/37021), [@Crassirostris](https://github.com/Crassirostris))

* Node Conformance Test: Containerize the node e2e test ([#31093](https://github.com/kubernetes/kubernetes/pull/31093), [@Random-Liu](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/36296), [@nikhiljindal](https://github.com/nikhiljindal))

* 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](https://github.com/kubernetes/kubernetes/pull/35484), [@smarterclayton](https://github.com/smarterclayton))

* 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](https://github.com/kubernetes/kubernetes/pull/36017), [@foxish](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/25532), [@mkulke](https://github.com/mkulke))
* [Kubelet] Add alpha support for `--cgroups-per-qos` using the configured `--cgroup-driver`. Disabled by default. ([#31546](https://github.com/kubernetes/kubernetes/pull/31546), [@derekwaynecarr](https://github.com/derekwaynecarr))
* Move Statefulset (previously PetSet) to v1beta1 ([#35731](https://github.com/kubernetes/kubernetes/pull/35731), [@janetkuo](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/36001), [@smarterclayton](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/35739), [@foxish](https://github.com/foxish))
* AWS: recognize us-east-2 region ([#35013](https://github.com/kubernetes/kubernetes/pull/35013), [@justinsb](https://github.com/justinsb))
* Eviction manager evicts based on inode consumption ([#35137](https://github.com/kubernetes/kubernetes/pull/35137), [@dashpole](https://github.com/dashpole))
* SELinux Overhaul ([#33663](https://github.com/kubernetes/kubernetes/pull/33663), [@pmorie](https://github.com/pmorie))
* Add SNI support to the apiserver ([#35109](https://github.com/kubernetes/kubernetes/pull/35109), [@sttts](https://github.com/sttts))
* The main kubernetes repository stops hosting archived version of released clients. Please use [client-go](https://github.com/kubernetes/client-go). ([#35928](https://github.com/kubernetes/kubernetes/pull/35928), [@caesarxuchao](https://github.com/caesarxuchao))
* Correct the article in generated documents ([#32557](https://github.com/kubernetes/kubernetes/pull/32557), [@asalkeld](https://github.com/asalkeld))
* Update PodAntiAffinity to ignore calls to subresources ([#35608](https://github.com/kubernetes/kubernetes/pull/35608), [@soltysh](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/35497), [@liggitt](https://github.com/liggitt))
* update list of vailable resources ([#32687](https://github.com/kubernetes/kubernetes/pull/32687), [@jouve](https://github.com/jouve))
* Remove stale volumes if endpoint/svc creation fails. ([#35285](https://github.com/kubernetes/kubernetes/pull/35285), [@humblec](https://github.com/humblec))

## Changelog since v1.4.0-alpha.3

### Experimental Features

* `kubeadm` (alpha) provides an easy way to securely bootstrap Kubernetes on Linux, see http://kubernetes.io/docs/kubeadm/ ([#33262](https://github.com/kubernetes/kubernetes/pull/33262), [@errordeveloper](https://github.com/errordeveloper))
* Alpha JWS Discovery API for locating an apiserver securely ([#32203](https://github.com/kubernetes/kubernetes/pull/32203), [@dgoodwin](https://github.com/dgoodwin))

### 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](https://github.com/kubernetes/kubernetes/pull/32386), [@liggitt](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/31250), [@derekwaynecarr](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/29929), [@madhusudancs](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/34029), [@liggitt](https://github.com/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](https://github.com/kubernetes/kubernetes/pull/33718), [@justinsb](https://github.com/justinsb))
* Federated deployment controller that supports the same api as the regular kubernetes deployment controller. ([#34109](https://github.com/kubernetes/kubernetes/pull/34109), [@mwielgus](https://github.com/mwielgus))
* Match GroupVersionKind against specific version ([#34010](https://github.com/kubernetes/kubernetes/pull/34010), [@soltysh](https://github.com/soltysh))
* fix yaml decode issue ([#34297](https://github.com/kubernetes/kubernetes/pull/34297), [@AdoHe](https://github.com/AdoHe))

* kubectl: Add external ip information to node when '-o wide' is used ([#33552](https://github.com/kubernetes/kubernetes/pull/33552), [@floreks](https://github.com/floreks))
* Update GCI base image: ([#34156](https://github.com/kubernetes/kubernetes/pull/34156), [@adityakali](https://github.com/adityakali))
  * Enabled VXLAN and IP_SET config options in kernel to support some networking tools (ebtools)
  * OpenSSL CVE fixes
* ContainerVm/GCI image: try to use ifdown/ifup if available ([#33595](https://github.com/kubernetes/kubernetes/pull/33595), [@freehan](https://github.com/freehan))
* Use manifest digest (as `docker-pullable://`) as ImageID when available (exposes a canonical, pullable image ID for containers). ([#33014](https://github.com/kubernetes/kubernetes/pull/33014), [@DirectXMan12](https://github.com/DirectXMan12))
* Add kubelet awareness to taint tolerant match caculator. ([#26501](https://github.com/kubernetes/kubernetes/pull/26501), [@resouer](https://github.com/resouer))
* Fix nil pointer issue when getting metrics from volume mounter ([#34251](https://github.com/kubernetes/kubernetes/pull/34251), [@jingxu97](https://github.com/jingxu97))
