Changelog since v1.7.7

Other notable changes

  • Ignore pods marked for deletion that exceed their grace period in ResourceQuota (#46542, @derekwaynecarr)
  • kubelet to master communication when doing node status updates now has a timeout to prevent indefinite hangs (#52176, @liggitt)
  • Bumped Heapster version to 1.4.3 - more details https://github.com/kubernetes/heapster/releases/tag/v1.4.3 (#53376, @loburm)
  • Delete the federation namespace from control plane instead of individual objects (#51768, @shashidharatd)
  • Bugfix: OpenAPI models may not get group-version-kind extension if kubernetes is vendored in another project (e.g. minikube). Kubectl 1.8 needs this extension to work with those projects. (#53152, @mbohlool)
  • Fix for Nodes in vSphere lacking an InternalIP. (#48760) (#49202, @cbonte)
  • [fluentd-gcp addon] Update Stackdriver plugin to version 0.6.7 (#52565, @crassirostris)
  • Fixes an issue with RBAC reconciliation that could cause duplicated subjects in some bootstrapped rolebindings on each restart of the API server. (#53239, @enj)
  • Restores redirect behavior for proxy subresources (#52933, @liggitt)
  • Fix panic in ControllerManager on GCE when it has a problem with creating external loadbalancer healthcheck (#52646, @gmarek)
  • custom resources that use unconventional pluralization now work properly with kubectl and garbage collection (#50012, @deads2k)
  • When performing a GET then PUT, the kube-apiserver must write the canonical representation of the object to etcd if the current value does not match. That allows external agents to migrate content in etcd from one API version to another, across different storage types, or across varying encryption levels. This fixes a bug introduced in 1.5 where we unintentionally stopped writing the newest data. (#48394, @smarterclayton)

Major Themes

Kubernetes 1.7 is a milestone release that adds security, stateful application, and extensibility features motivated by widespread production use of Kubernetes.

Security enhancements in this release include encrypted secrets (alpha), network policy for pod-to-pod communication, the node authorizer to limit Kubelet access to API resources, and Kubelet client / server TLS certificate rotation (alpha).

Major features for stateful applications include automated updates to StatefulSets, enhanced updates for DaemonSets, a burst mode for faster StatefulSets scaling, and (alpha) support for local storage.

Extensibility features include API aggregation (beta), CustomResourceDefinitions (beta) in favor of ThirdPartyResources, support for extensible admission controllers (alpha), pluggable cloud providers (alpha), and container runtime interface (CRI) enhancements.

Action Required Before Upgrading

Network

  • NetworkPolicy has been promoted from extensions/v1beta1 to the new networking.k8s.io/v1 API group. The structure remains unchanged from the v1beta1 API. The net.beta.kubernetes.io/network-policy annotation on Namespaces (used to opt in to isolation) has been removed. Instead, isolation is now determined on a per-pod basis. A NetworkPolicy may target a pod for isolation by including the pod in its spec.podSelector. Targeted Pods accept the traffic specified in the respective NetworkPolicy (and nothing else). Pods not targeted by any NetworkPolicy accept all traffic by default. (#39164, @danwinship)

    Action Required: When upgrading to Kubernetes 1.7 (and a network plugin that supports the new NetworkPolicy v1 semantics), you should consider the following.

    The v1beta1 API used an annotation on Namespaces to activate the DefaultDeny policy for an entire Namespace. To activate default deny in the v1 API, you can create a NetworkPolicy that matches all Pods but does not allow any traffic:

    kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
  name: default-deny
spec:
  podSelector:

    This will ensure that Pods that aren't matched by any other NetworkPolicy will continue to be fully-isolated, as they were in v1beta1.

    In Namespaces that previously did not have the "DefaultDeny" annotation, you should delete any existing NetworkPolicy objects. These had no effect in the v1beta1 API, but with v1 semantics they might cause some traffic to be unintentionally blocked.

Storage

  • Alpha volume provisioning is removed and default storage class should be used instead. (#44090, @NickrenREN)

  • Portworx volume driver no longer has to run on the master. (#45518, @harsh-px)

  • Default behavior in Cinder storageclass is changed. If availability is not specified, the zone is chosen by algorithm. It makes possible to spread stateful pods across many zones. (#44798, @zetaab)

  • PodSpecs containing parent directory references such as .. (for example, ../bar) in hostPath volume path or in volumeMount subpaths must be changed to the simple absolute path. Backsteps .. are no longer allowed.(#47290, @jhorwit2).

API Machinery

  • The Namespace API object no longer supports the deletecollection operation. (#46407, @liggitt)

  • The following alpha API groups were unintentionally enabled by default in previous releases, and will no longer be enabled by default in v1.8: (#47690, @caesarxuchao)

    • rbac.authorization.k8s.io/v1alpha1

    • settings.k8s.io/v1alpha1

    • If you wish to continue using them in v1.8, please enable them explicitly using the --runtime-config flag on the apiserver (for example, --runtime-config="rbac.authorization.k8s.io/v1alpha1,settings.k8s.io/v1alpha1")

  • cluster/update-storage-objects.sh now supports updating StorageClasses in etcd to storage.k8s.io/v1. You must do this prior to upgrading to 1.8. (#46116, @ncdc)

Controller Manager

  • kube-controller-manager has dropped support for the --insecure-experimental-approve-all-kubelet-csrs-for-group flag. It is accepted in 1.7, but ignored. Instead, the csrapproving controller uses authorization checks to determine whether to approve certificate signing requests: (#45619, @mikedanese)

    • Before upgrading, users must ensure their controller manager will enable the csrapproving controller, create an RBAC ClusterRole and ClusterRoleBinding to approve CSRs for the same group, then upgrade. Example roles to enable the equivalent behavior can be found in the TLS bootstrapping documentation.

kubectl (CLI)

  • kubectl create role and kubectl create clusterrole invocations must be updated to specify multiple resource names as repeated --resource-name arguments instead of comma-separated arguments to a single --resource-name argument. E.g. --resource-name=x,y must become --resource-name x --resource-name y (#44950, @xilabao)

  • kubectl create rolebinding and kubectl create clusterrolebinding invocations must be updated to specify multiple subjects as repeated --user, --group, or --serviceaccount arguments instead of comma-separated arguments to a single --user, --group, or --serviceaccount. E.g. --user=x,y must become --user x --user y (#43903, @xilabao)

kubeadm

  • kubeadm: Modifications to cluster-internal resources installed by kubeadm will be overwritten when upgrading from v1.6 to v1.7. (#47081, @luxas)

  • kubeadm deb/rpm packages: cAdvisor doesn't listen on 0.0.0.0:4194 without authentication/authorization because of the possible information leakage. The cAdvisor API can still be accessed via https://{node-ip}:10250/stats/, though. (kubernetes/release#356, @luxas)

Cloud Providers

  • Azure: Container permissions for provisioned volumes have changed to private. If you have existing Azure volumes that were created by Kubernetes v1.6.0-v1.6.5, you should change the permissions on them manually. (#47605, @brendandburns)

  • GKE/GCE: New and upgraded 1.7 GCE/GKE clusters no longer have an RBAC ClusterRoleBinding that grants the cluster-admin ClusterRole to the default service account in the kube-system Namespace. (#46750, @cjcullen). If this permission is still desired, run the following command to explicitly grant it, either before or after upgrading to 1.7:

    kubectl create clusterrolebinding kube-system-default --serviceaccount=kube-system:default --clusterrole=cluster-admin

Known Issues

Populated via v1.7.x known issues / FAQ accumulator

  • The kube-apiserver discovery APIs (for example, /apis) return information about the API groups being served, and can change dynamically. During server startup, prior to the server reporting healthy (via /healthz), not all API groups may be reported. Wait for the server to report healthy (via /healthz) before depending on the information provided by the discovery APIs. Additionally, since the information returned from the discovery APIs may change dynamically, a cache of the results should not be considered authoritative. ETag support is planned in a future version to facilitate client caching. (#47977, #44957)

  • The DaemonSet controller will evict running Pods that do not tolerate the NoSchedule taint if the taint is added to a Node. There is an open PR (#48189) to resolve this issue, but as this issue also exists in 1.6, and as we do not wish to risk release stability by merging it directly prior to a release without sufficient testing, we have decided to defer merging the PR until the next point release for each minor version (#48190).

  • Protobuf serialization does not distinguish between [] and null. API fields previously capable of storing and returning either [] and null via JSON API requests (for example, the Endpoints subsets field) can now store only null when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6). JSON API clients should tolerate null values for such fields, and treat null and [] as equivalent in meaning unless specifically documented otherwise for a particular field. (#44593)

  • Local volume source paths that are directories and not mount points fail to unmount. A fix is in process (#48331).

  • Services of type LoadBalancer (on GCE/GKE) that have static IP addresses will cause the Service Controller to panic and thereby causing the kube-controller-manager to crash loop. (#48848)

Deprecations

Cluster provisioning scripts

Client libraries

  • Swagger 1.2 spec (/swaggerapi/*) is deprecated. Please use OpenAPI instead.

DaemonSet

  • DaemonSet’s spec.templateGeneration has been deprecated. (#45924, @janetkuo)

kube-proxy

  • In 1.7, the kube-proxy component has been converted to use a configuration file. The old flags still work in 1.7, but they are being deprecated and will be removed in a future release. Cluster administrators are advised to switch to using the configuration file, but no action is strictly necessary in 1.7. (#34727, @ncdc)

Namespace

  • The Namespace API object no longer supports the deletecollection operation. (#46407, @liggitt)

Scheduling

  • If you are using AffinityInAnnotations=true in --feature-gates, then the 1.7 release is your last opportunity to convert from specifying affinity/anti-affinity using the scheduler.alpha.kubernetes.io/affinity annotation on Pods, to using the Affinity field of PodSpec. Support for the alpha version of node and pod affinity (which uses the scheduler.alpha.kubernetes.io/affinity annotations on Pods) is going away in Kubernetes 1.8 (not this release, but the next release). If you have not enabled AffinityInAnnotations=true in --feature-gates, then this change does not affect you.

Notable 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

Kubefed

  • Deprecate the --secret-name flag from kubefed join, instead generating the secret name arbitrarily. (#42513, @perotinus)

Kubernetes API

User Provided Extensions

Application Deployment

StatefulSet

  • [beta] StatefulSet supports RollingUpdate and OnDelete update strategies.

  • [alpha] StatefulSet authors should be able to relax the ordering and parallelism policies for software that can safely support rapid, out-of-order changes.

DaemonSet

Deployments

  • [beta] Deployments uses a hashing collision avoidance mechanism that ensures new rollouts will not block on hashing collisions anymore. (kubernetes/features#287)

PodDisruptionBudget

  • [beta] PodDisruptionBudget has a new field MaxUnavailable, which allows users to specify the maximum number of disruptions that can be tolerated during eviction. For more information, see Pod Disruptions and Specifying a Disruption Budget for your Application.
  • PodDisruptionBudget now uses ControllerRef to make the right decisions about Pod eviction even if the built in application controllers have overlapping selectors.

Security

Admission Control

TLS Bootstrapping

Audit Logging

  • [alpha] Advanced Auditing enhances the Kubernetes API audit logging capabilities through a customizable policy, pluggable audit backends, and richer audit data.

Encryption at Rest

Node Authorization

  • [beta] A new Node authorization mode and NodeRestriction admission plugin, when used in combination, limit nodes' access to specific APIs, so that they may only modify their own Node API object, only modify Pod objects bound to themselves, and only retrieve secrets and configmaps referenced by pods bound to themselves. See Using Node Authorization for more information.

Application Autoscaling

Horizontal Pod Autoscaler

Cluster Lifecycle

kubeadm

Cloud Provider Support

Cluster Federation

Placement Policy

  • [alpha] The federation-apiserver now supports a SchedulingPolicy admission controller that enables policy-based control over placement of federated resources. For more information, see Set up placement policies in Federation.

Volume Plugins

Metrics

Other notable changes

Admission plugin

  • OwnerReferencesPermissionEnforcement admission plugin ignores pods/status. (#45747, @derekwaynecarr)

  • Ignored mirror pods in PodPreset admission plugin. (#45958, @k82cn)

API Machinery

  • The protobuf serialization of API objects has been updated to store maps in a predictable order to ensure that the representation of that object does not change when saved into etcd. This prevents the same object from being seen as being modified, even when no values have changed. (#47701, @smarterclayton)

  • API resource discovery now includes the singularName used to refer to the resource. (#43312, @deads2k)

  • Enhance the garbage collection admission plugin so that a user who doesn't have delete permission of the owning object cannot modify the blockOwnerDeletion field of existing ownerReferences, or add new ownerReferences with blockOwnerDeletion=true (#43876, @caesarxuchao)

  • Exec and portforward actions over SPDY now properly handle redirects sent by the Kubelet (#44451, @ncdc)

  • The proxy subresource APIs for nodes, services, and pods now support the HTTP PATCH method. (#44929, @liggitt)

  • The Categories []string field on discovered API resources represents the list of group aliases (e.g. "all") that each resource belongs to. (#43338, @fabianofranz)

  • [alpha] The Kubernetes API supports retrieving tabular output for API resources via a new mime-type application/json;as=Table;v=v1alpha1;g=meta.k8s.io. The returned object (if the server supports it) will be of type meta.k8s.io/v1alpha1 with Table, and contain column and row information related to the resource. Each row will contain information about the resource - by default it will be the object metadata, but callers can add the ?includeObject=Object query parameter and receive the full object. In the future kubectl will use this to retrieve the results of kubectl get. (#40848, @smarterclayton)

  • The behavior of some watch calls to the server when filtering on fields was incorrect. If watching objects with a filter, when an update was made that no longer matched the filter a DELETE event was correctly sent. However, the object that was returned by that delete was not the (correct) version before the update, but instead, the newer version. That meant the new object was not matched by the filter. This was a regression from behavior between cached watches on the server side and uncached watches, and thus broke downstream API clients. (#46223, @smarterclayton)

  • OpenAPI spec is now available in protobuf binary and gzip format (with ETag support) (#45836, @mbohlool)

  • Updating apiserver to return UID of the deleted resource. Clients can use this UID to verify that the resource was deleted or waiting for finalizers. (#45600, @nikhiljindal)

  • Fix incorrect conflict errors applying strategic merge patches to resources. (#43871, @liggitt)

  • Fix init container status reporting when active deadline is exceeded. (#46305, @sjenning)

  • Moved qos to api.helpers. (#44906, @k82cn)

  • Fix issue with the resource quota controller causing add quota to be resynced at the wrong (#45685, @derekwaynecarr)

  • Added Group/Version/Kind and Action extension to OpenAPI Operations (#44787, @mbohlool)

  • Make clear that meta.KindToResource is only a guess (#45272, @sttts)

  • Add APIService conditions (#43301, @deads2k)

  • Create and push a docker image for the cloud-controller-manager (#45154, @luxas)

  • Deprecated Binding objects in 1.7. (#47041, @k82cn)

  • Adds the Categories []string field to API resources, which represents the list of group aliases (e.g. "all") that every resource belongs to. (#43338, @fabianofranz)

  • --service-account-lookup now defaults to true, requiring the Secret API object containing the token to exist in order for a service account token to be valid. This enables service account tokens to be revoked by deleting the Secret object containing the token. (#44071, @liggitt)

  • API Registration is now in beta. (#45247, @mbohlool)

  • The Kubernetes API server now exits if it encounters a networking failure (e.g. the networking interface hosting its address goes away) to allow a process manager (systemd/kubelet/etc) to react to the problem. Previously the server would log the failure and try again to bind to its configured address:port. (#42272, @marun)

  • The Prometheus metrics for the kube-apiserver for tracking incoming API requests and latencies now return the subresource label for correctly attributing the type of API call. (#46354, @smarterclayton)

  • kube-apiserver now drops unneeded path information if an older version of Windows kubectl sends it. (#44421, @mml)

Application autoscaling

  • Make "upscale forbidden window" and "downscale forbidden window" duration configurable in arguments of kube-controller-manager. (#42101, @Dmitry1987)

Application Deployment

  • StatefulSetStatus now tracks replicas, readyReplicas, currentReplicas, and updatedReplicas. The semantics of replicas is now consistent with DaemonSet and ReplicaSet, and readyReplicas has the semantics that replicas did prior to 1.7 (#46669, @kow3ns).

  • ControllerRevision type has been added for StatefulSet and DaemonSet history. Clients should not depend on the stability of this type as it may change, as necessary, in future releases to support StatefulSet and DaemonSet update and rollback. We enable this type as we do with beta features, because StatefulSet update and DaemonSet update are enabled. (#45867, @kow3ns)

  • PodDisruptionBudget now uses ControllerRef to decide which controller owns a given Pod, so it doesn't get confused by controllers with overlapping selectors. (#45003, @krmayankk)

  • Deployments are updated to use (1) a more stable hashing algorithm (fnv) than the previous one (adler) and (2) a hashing collision avoidance mechanism that will ensure new rollouts will not block on hashing collisions anymore. (#44774, @kargakis)(kubernetes/features#287)

  • Deployments and DaemonSets rollouts are considered complete when all of the desired replicas are updated and available. This change affects kubectl rollout status and Deployment condition. (#44672, @kargakis)

  • Job controller now respects ControllerRef to avoid fighting over Pods. (#42176, @enisoc)

  • CronJob controller now respects ControllerRef to avoid fighting with other controllers. (#42177, @enisoc)

Cluster Autoscaling

  • Cluster Autoscaler 0.6. More information available here.

    • Allow configuration of a single security group for ELBs (#45500, @nbutton23)

    • Remove check that forces loadBalancerSourceRanges to be 0.0.0.0/0. (#38636, @dhawal55)

      • Allow setting KubernetesClusterID or KubernetesClusterTag in combination with VPC. (#42512, @scheeles)

      • Start recording cloud provider metrics for AWS (#43477, @gnufied)

      • AWS: Batch DescribeInstance calls with nodeNames to 150 limit, to stay within AWS filter limits. (#47516, @gnufied)

    • Support node port health check (#43585, @foolusion)

    • Support for ELB tagging by users (#45932, @lpabon)

  • Azure:

  • GCP:

    • Bump GLBC version to 0.9.5 - fixes loss of manually modified GCLB health check settings upon upgrade from pre-1.6.4 to either 1.6.4 or 1.6.5. (#47567, @nicksardo)

    • [beta] Support creation of GCP Internal Load Balancers from Service objects (#46663, @nicksardo)

    • GCE installs will now avoid IP masquerade for all RFC-1918 IP blocks, rather than just 10.0.0.0/8. This means that clusters can be created in 192.168.0.0./16 and 172.16.0.0/12 while preserving the container IPs (which would be lost before). (#46473, @thockin)

    • The Calico version included in kube-up for GCE has been updated to v2.2. (#38169, @caseydavenport)

    • Add ip-masq-agent addon to the addons folder which is used in GCE if --non-masquerade-cidr is set to 0/0 (#46038, @dnardo)

    • Enable kubelet csr bootstrap in GCE/GKE (#40760, @mikedanese)

    • Adds support for allocation of pod IPs via IP aliases. (#42147, @bowei)

      • gce kube-up: The Node authorization mode and NodeRestriction admission controller are now enabled (#46796, @mikedanese)

      • Tokens retrieved from Google Cloud with application default credentials will not be cached if the client fails authorization (#46694, @matt-tyler)

      • Add metrics to all major gce operations {latency, errors} (#44510, @bowei)

        • The new metrics are:

        • cloudprovider_gce_api_request_duration_seconds{request, region, zone}

        • cloudprovider_gce_api_request_errors{request, region, zone}

        • request is the specific function that is used.

        • region is the target region (Will be "<n/a>" if not applicable)

        • zone is the target zone (Will be "<n/a>" if not applicable)

        • Note: this fixes some issues with the previous implementation of metrics for disks:

          • Time duration tracked was of the initial API call, not the entire operation.

          • Metrics label tuple would have resulted in many independent histograms stored, one for each disk. (Did not aggregate well).

    • Fluentd now tolerates all NoExecute Taints when run in gcp configuration. (#45715, @gmarek)

      • Taints support in gce/salt startup scripts. (#47632, @mwielgus)

      • GCE installs will now avoid IP masquerade for all RFC-1918 IP blocks, rather than just 10.0.0.0/8. This means that clusters can (#46473, @thockin) be created in 192.168.0.0./16 and 172.16.0.0/12 while preserving the container IPs (which would be lost before).

      • Support running Ubuntu image on GCE node (#44744, @yguo0905)

    • The gce metadata server can now be hidden behind a proxy, hiding the kubelet's token. (#45565, @Q-Lee)

  • Remove Initializers from admission-control in kubernetes-master charm for pre-1.7 (#46987, @Cynerva)

  • Added state guards to the idle_status messaging in the kubernetes-master charm to make deployment faster on initial deployment. (#47183, @chuckbutler)

Cluster federation

  • Features:

    • Adds annotations to all Federation objects created by kubefed. (#42683, @perotinus)

      • Mechanism of adding federation domain maps to kube-dns deployment via --federations flag is superseded by adding/updating federations key in kube-system/kube-dns configmap. If user is using kubefed tool to join cluster federation, adding federation domain maps to kube-dns is already taken care by kubefed join and does not need further action.

      • Prints out status updates when running kubefed init (#41849, @perotinus)

    • CRI has been moved to package pkg/kubelet/apis/cri/v1alpha1/runtime as part of Kubelet API path cleanup. (#47113, @feiskyer)

Scheduling

Security

  • Features:

    • Permission to use a PodSecurityPolicy can now be granted within a single namespace by allowing the use verb on the podsecuritypolicies resource within the namespace. (#42360, @liggitt)

    • Break the 'certificatesigningrequests' controller into a 'csrapprover' controller and 'csrsigner' controller. (#45514, @mikedanese)

    • kubectl auth can-i now supports non-resource URLs (#46432, @CaoShuFeng)

    • Promote kubelet tls bootstrap to beta. Add a non-experimental flag to use it and deprecate the old flag. (#46799, @mikedanese)

    • Add the alpha.image-policy.k8s.io/failed-open=true annotation when the image policy webhook encounters an error and fails open. (#46264, @Q-Lee)

    • Add an AEAD encrypting transformer for storing secrets encrypted at rest (#41939, @smarterclayton)

    • Add secretbox and AES-CBC encryption modes to at rest encryption. AES-CBC is considered superior to AES-GCM because it is resistant to nonce-reuse attacks, and secretbox uses Poly1305 and XSalsa20. (#46916, @smarterclayton)

  • Bug fixes:

    • Make gcp auth provider not to override the Auth header if it's already exits (#45575, @wanghaoran1988)

    • The oidc client plugin has reduce round trips and fix scopes requested (#45317, @ericchiang)

    • API requests using impersonation now include the system:authenticated group in the impersonated user automatically. (#44076, @liggitt)

    • RBAC role and rolebinding auto-reconciliation is now performed only when the RBAC authorization mode is enabled. (#43813, @liggitt)

    • PodSecurityPolicy now recognizes pods that specify runAsNonRoot: false in their security context and does not overwrite the specified value (#47073, @Q-Lee)

    • Tokens retrieved from Google Cloud with application default credentials will not be cached if the client fails authorization (#46694, @matt-tyler)

    • Update kube-dns, metadata-proxy, and fluentd-gcp, event-exporter, prometheus-to-sd, and ip-masq-agent addons with new base images containing fixes for CVE-2016-4448, CVE-2016-9841, CVE-2016-9843, CVE-2017-1000366, CVE-2017-2616, and CVE-2017-9526. (#47877, @ixdy)

    • Fixed an issue mounting the wrong secret into pods as a service account token. (#44102, @ncdc)

Scalability

  • The HorizontalPodAutoscaler controller will now only send updates when it has new status information, reducing the number of writes caused by the controller. (#47078, @DirectXMan12)

Changelog since v1.7.0-beta.2

Action Required

  • The following alpha API groups were unintentionally enabled by default in previous releases, and will no longer be enabled by default in v1.8: (#47690, @caesarxuchao)
    • rbac.authorization.k8s.io/v1alpha1
    • settings.k8s.io/v1alpha1
    • If you wish to continue using them in v1.8, please enable them explicitly using the --runtime-config flag of the apiserver (for example, --runtime-config="rbac.authorization.k8s.io/v1alpha1,settings.k8s.io/v1alpha1")
  • Paths containing backsteps (for example, "../bar") are no longer allowed in hostPath volume paths, or in volumeMount subpaths (#47290, @jhorwit2)
  • Azure: Change container permissions to private for provisioned volumes. If you have existing Azure volumes that were created by Kubernetes v1.6.0-v1.6.5, you should change the permissions on them manually. (#47605, @brendandburns)

Other notable changes

  • Update kube-dns, metadata-proxy, and fluentd-gcp, event-exporter, prometheus-to-sd, and ip-masq-agent addons with new base images containing fixes for CVE-2016-4448, CVE-2016-9841, CVE-2016-9843, CVE-2017-1000366, CVE-2017-2616, and CVE-2017-9526. (#47877, @ixdy)

Changelog since v1.7.0-alpha.4

Action Required

  • kube-apiserver: a new authorization mode (--authorization-mode=Node) authorizes nodes to access secrets, configmaps, persistent volume claims and persistent volumes related to their pods. (#46076, @liggitt) * Nodes must use client credentials that place them in the system:nodes group with a username of system:node:<nodeName> in order to be authorized by the node authorizer (the credentials obtained by the kubelet via TLS bootstrapping satisfy these requirements) * When used in combination with the RBAC authorization mode (--authorization-mode=Node,RBAC), the system:node role is no longer automatically granted to the system:nodes group.
  • kube-controller-manager has dropped support for the --insecure-experimental-approve-all-kubelet-csrs-for-group flag. Instead, the csrapproving controller uses authorization checks to determine whether to approve certificate signing requests: (#45619, @mikedanese) * requests for a TLS client certificate for any node are approved if the CSR creator has create permission on the certificatesigningrequests resource and nodeclient subresource in the certificates.k8s.io API group * requests from a node for a TLS client certificate for itself are approved if the CSR creator has create permission on the certificatesigningrequests resource and the selfnodeclient subresource in the certificates.k8s.io API group * requests from a node for a TLS serving certificate for itself are approved if the CSR creator has create permission on the certificatesigningrequests resource and the selfnodeserver subresource in the certificates.k8s.io API group
  • Support updating storageclasses in etcd to storage.k8s.io/v1. You must do this prior to upgrading to 1.8. (#46116, @ncdc)
  • The namespace API object no longer supports the deletecollection operation. (#46407, @liggitt)
  • NetworkPolicy has been moved from extensions/v1beta1 to the new (#39164, @danwinship) networking.k8s.io/v1 API group. The structure remains unchanged from the beta1 API. The net.beta.kubernetes.io/network-policy annotation on Namespaces to opt in to isolation has been removed. Instead, isolation is now determined at a per-pod level, with pods being isolated if there is any NetworkPolicy whose spec.podSelector targets them. Pods that are targeted by NetworkPolicies accept traffic that is accepted by any of the NetworkPolicies (and nothing else), and pods that are not targeted by any NetworkPolicy accept all traffic by default. Action Required: When upgrading to Kubernetes 1.7 (and a network plugin that supports the new NetworkPolicy v1 semantics), to ensure full behavioral compatibility with v1beta1:

    1. In Namespaces that previously had the "DefaultDeny" annotation, you can create equivalent v1 semantics by creating a NetworkPolicy that matches all pods but does not allow any traffic:

          kind: NetworkPolicy
    apiVersion: networking.k8s.io/v1
    metadata:
      name: default-deny
    spec:
      podSelector:

      This will ensure that pods that aren't matched by any other NetworkPolicy will continue to be fully-isolated, as they were before.

    2. In Namespaces that previously did not have the "DefaultDeny" annotation, you should delete any existing NetworkPolicy objects. These would have had no effect before, but with v1 semantics they might cause some traffic to be blocked that you didn't intend to be blocked.

  • Stackdriver cluster logging now deploys a new component to export Kubernetes events. (#46700, @crassirostris)
  • Alpha feature: allows users to set storage limit to isolate EmptyDir volumes. It enforces the limit by evicting pods that exceed their storage limits (#45686, @jingxu97)
  • Adds the Categories []string field to API resources, which represents the list of group aliases (e.g. "all") that every resource belongs to. (#43338, @fabianofranz)

  • With --feature-gates=RotateKubeletClientCertificate=true set, the kubelet will (#41912, @jcbsmpsn)
    • request a client certificate from the API server during the boot cycle and pause
    • waiting for the request to be satisfied. It will continually refresh the certificate
    • as the certificates expiration approaches.
  • The Kubernetes API supports retrieving tabular output for API resources via a new mime-type application/json;as=Table;v=v1alpha1;g=meta.k8s.io. The returned object (if the server supports it) will be of type meta.k8s.io/v1alpha1 with Table, and contain column and row information related to the resource. Each row will contain information about the resource - by default it will be the object metadata, but callers can add the ?includeObject=Object query parameter and receive the full object. In the future kubectl will use this to retrieve the results of kubectl get. (#40848, @smarterclayton)

    • request a server certificate from the API server during the boot cycle and pause
    • waiting for the request to be satisfied. It will continually refresh the certificate as
    • the certificates expiration approaches.

  • Fix log spam due to unnecessary status update when node is deleted. (#45923, @verult)
  • GCE installs will now avoid IP masquerade for all RFC-1918 IP blocks, rather than just 10.0.0.0/8. This means that clusters can (#46473, @thockin)
    • be created in 192.168.0.0./16 and 172.16.0.0/12 while preserving the container IPs (which would be lost before).
  • set selector and set subject no longer print "running in local/dry-run mode..." at the top, so their output can be piped as valid yaml or json (#46507, @bboreham)
  • ControllerRevision type added for StatefulSet and DaemonSet history. (#45867, @kow3ns)
  • Bump Go version to 1.8.3 (#46429, @wojtek-t)
  • Upgrade Elasticsearch Addon to v5.4.0 (#45589, @it-svit)
  • PodDisruptionBudget now uses ControllerRef to decide which controller owns a given Pod, so it doesn't get confused by controllers with overlapping selectors. (#45003, @krmayankk)
  • aws: Support for ELB tagging by users (#45932, @lpabon)
  • Portworx volume driver no longer has to run on the master. (#45518, @harsh-px)
  • kube-proxy: ratelimit runs of iptables by sync-period flags (#46266, @thockin)
  • Deployments are updated to use (1) a more stable hashing algorithm (fnv) than the previous one (adler) and (2) a hashing collision avoidance mechanism that will ensure new rollouts will not block on hashing collisions anymore. (#44774, @kargakis)
  • The Prometheus metrics for the kube-apiserver for tracking incoming API requests and latencies now return the subresource label for correctly attributing the type of API call. (#46354, @smarterclayton)
  • Add Simplified Chinese translation for kubectl (#45573, @shiywang)
  • The --namespace flag is now honored for in-cluster clients that have an empty configuration. (#46299, @ncdc)
  • Fix init container status reporting when active deadline is exceeded. (#46305, @sjenning)
  • Improves performance of Cinder volume attach/detach operations (#41785, @jamiehannaford)
  • GCE and AWS dynamic provisioners extension: admins can configure zone(s) in which a persistent volume shall be created. (#38505, @pospispa)
  • Break the 'certificatesigningrequests' controller into a 'csrapprover' controller and 'csrsigner' controller. (#45514, @mikedanese)
  • Modifies kubefed to create and the federation controller manager to use credentials associated with a service account rather than the user's credentials. (#42042, @perotinus)
  • Adds a MaxUnavailable field to PodDisruptionBudget (#45587, @foxish)
  • The behavior of some watch calls to the server when filtering on fields was incorrect. If watching objects with a filter, when an update was made that no longer matched the filter a DELETE event was correctly sent. However, the object that was returned by that delete was not the (correct) version before the update, but instead, the newer version. That meant the new object was not matched by the filter. This was a regression from behavior between cached watches on the server side and uncached watches, and thus broke downstream API clients. (#46223, @smarterclayton)
  • vSphere cloud provider: vSphere Storage policy Support for dynamic volume provisioning (#46176, @BaluDontu)
  • Add support for emitting metrics from openstack cloudprovider about storage operations. (#46008, @NickrenREN)
  • 'kubefed init' now supports overriding the default etcd image name with the --etcd-image parameter. (#46247, @marun)
  • remove the elasticsearch template (#45952, @harryge00)
  • Adds the CustomResourceDefinition (crd) types to the kube-apiserver. These are the successors to ThirdPartyResource. See https://github.com/kubernetes/community/blob/master/contributors/design-proposals/api-machinery/thirdpartyresources.md for more details. (#46055, @deads2k)
  • StatefulSets now include an alpha scaling feature accessible by setting the spec.podManagementPolicy field to Parallel. The controller will not wait for pods to be ready before adding the other pods, and will replace deleted pods as needed. Since parallel scaling creates pods out of order, you cannot depend on predictable membership changes within your set. (#44899, @smarterclayton)
  • fix kubelet event recording for selected events. (#46246, @derekwaynecarr)
  • Moved qos to api.helpers. (#44906, @k82cn)
  • Kubelet PLEG updates the relist timestamp only after successfully relisting. (#45496, @andyxning)
  • OpenAPI spec is now available in protobuf binary and gzip format (with ETag support) (#45836, @mbohlool)
  • Added support to a hierarchy of kubectl plugins (a tree of plugins as children of other plugins). (#45981, @fabianofranz)
    • Added exported env vars to kubectl plugins so that plugin developers have access to global flags, namespace, the plugin descriptor and the full path to the caller binary.
  • Ignored mirror pods in PodPreset admission plugin. (#45958, @k82cn)
  • Don't try to attach volume to new node if it is already attached to another node and the volume does not support multi-attach. (#45346, @codablock)
  • The Calico version included in kube-up for GCE has been updated to v2.2. (#38169, @caseydavenport)
  • Kubelet: Fix image garbage collector attempting to remove in-use images. (#46121, @Random-Liu)
  • Add ip-masq-agent addon to the addons folder which is used in GCE if --non-masquerade-cidr is set to 0/0 (#46038, @dnardo)
  • Fix serialization of EnforceNodeAllocatable (#44606, @ivan4th)
  • Add --write-config-to flag to kube-proxy to allow users to write the default configuration settings to a file. (#45908, @ncdc)
  • The NodeRestriction admission plugin limits the Node and Pod objects a kubelet can modify. In order to be limited by this admission plugin, kubelets must use credentials in the system:nodes group, with a username in the form system:node:<nodeName>. Such kubelets will only be allowed to modify their own Node API object, and only modify Pod API objects that are bound to their node. (#45929, @liggitt)
  • vSphere cloud provider: Report same Node IP as both internal and external. (#45201, @abrarshivani)
  • The options passed to a flexvolume plugin's mount command now contains the pod name (kubernetes.io/pod.name), namespace (kubernetes.io/pod.namespace), uid (kubernetes.io/pod.uid), and service account name (kubernetes.io/serviceAccount.name). (#39488, @liggitt)

  • A new field hostAliases has been added to pod.spec to support adding entries to a Pod's /etc/hosts file. (#44641, @rickypai)
  • Added CIFS PV support for Juju Charms (#45117, @chuckbutler)
  • Some container runtimes share a process (PID) namespace for all containers in a pod. This will become the default for Docker in a future release of Kubernetes. You can preview this functionality if running with the CRI and Docker 1.13.1 by enabling the --experimental-docker-enable-shared-pid kubelet flag. (#41583, @verb)
  • add APIService conditions (#43301, @deads2k)

    • cloudprovider_gce_api_request_errors{request, region, zone}

    • request is the specific function that is used.

    • Note: this fixes some issues with the previous implementation of

    • metrics for disks:

      • Time duration tracked was of the initial API call, not the entire

    • operation.

      • Metrics label tuple would have resulted in many independent

    • histograms stored, one for each disk. (Did not aggregate well).

  • Update kubernetes-e2e charm to use snaps (#45044, @Cynerva)
  • Log the error (if any) in e2e metrics gathering step (#45039, @shyamjvs)

  • Resolves juju vsphere hostname bug showing only a single node in a scaled node-pool. (#44780, @chuckbutler)
  • kubectl commands run inside a pod using a kubeconfig file now use the namespace specified in the kubeconfig file, instead of using the pod namespace. If no kubeconfig file is used, or the kubeconfig does not specify a namespace, the pod namespace is still used as a fallback. (#44570, @liggitt)
  • This adds support for CNI ConfigLists, which permit plugin chaining. (#42202, @squeed)
  • API requests using impersonation now include the system:authenticated group in the impersonated user automatically. (#44076, @liggitt)

  • Refactoring reorganize taints function in kubectl to expose operations (#43171, @ravisantoshgudimetla)
  • The Kubernetes API server now exits if it encounters a networking failure (e.g. the networking interface hosting its address goes away) to allow a process manager (systemd/kubelet/etc) to react to the problem. Previously the server would log the failure and try again to bind to its configured address:port. (#42272, @marun)
  • Fixes a bug in the kubernetes-worker Juju charm code that attempted to give kube-proxy more than one api endpoint. (#44677, @wwwtyro)
  • Fixes a missing comma in a list of strings. (#44678, @wwwtyro)
  • Fix ceph-secret type to kubernetes.io/rbd in kubernetes-master charm (#44635, @Cynerva)
