1.14.3-gke.11
GKE 1.14 is generally available.
Upgrading
Before upgrading clusters to GKE v1.14, you must review the known issues and urgent upgrade notes.
For example, the default RBAC policy no longer grants access to discovery and permission-checking APIs, and you must take specific action to preserve the old behavior for newly-created cluster users.
Differences between GKE v1.14.x and Kubernetes 1.14
GKE v1.14.x has the following differences from Kubernetes 1.14.x:
Storage Migrator is not supported on GKE v1.14.x.
CSI Inline Volumes (Alpha) are not supported on GKE v1.14.x.
-
Huge Pages is not supported on GKE 1.14.x. If you are interested in support for Huge Pages, register your interest.
New features
Pod Ready++ is generally available and supported on GKE v1.14.x.
Pod priority and preemption is generally available and supported on GKE v1.14.x.
The RunAsGroup feature has been promoted to beta and enabled by default. PodSpec and PodSecurityPolicy objects can be used to control the primary GID of containers on Docker and containerd runtimes.
Early-access to test Windows containers is now available. If you are interested in testing Windows containers, fill out this form.
Other changes
The node.k8s.io
API group and
runtimeclasses.node.k8s.io
resource
have been migrated to a built-in API. If you were using RuntimeClasses,
you must recreate each of them after upgrading, and also delete the
runtimeclasses.node.k8s.io
CRD. RuntimeClasses can no
longer be created without a defined handler.
When creating a new GKE cluster, Stackdriver Kubernetes Engine Monitoring is now the default Stackdriver support option. This is a change from prior versions where Stackdriver Logging and Stackdriver Monitoring were the default Stackdriver support option. For more information, see Overview of Stackdriver support for GKE.
OS and Arch information is now recorded in kubernetes.io/os
and kubernetes.io/arch
labels on Node objects. The previous
labels (beta.kubernetes.io/os
and
beta.kubernetes.io/arch
) are still recorded, but are
deprecated and targeted for removal in Kubernetes 1.18.
Known Issues
Users with the Quobyte Volume plugin are advised not to upgrade between GKE 1.13.x and 1.14.x due to an issue with Kubernetes 1.14. This will be fixed in an upcoming release.

Version updates
GKE cluster versions have been updated as detailed in the following sections. See these instructions to get a full list of the Kubernetes versions you can run on your GKE masters and nodes, and to review the Rollout schedule.
Important information about v1.10.x nodes
In addition to GKE's version policy, Kubernetes has a version skew policy of supporting only the three newest minor versions. Older versions are not guaranteed to receive bug fixes or security updates, and the control plane may become incompatible with nodes running unsupported versions.
Specifically, the Kubernetes v1.13.x control plane is not compatible with nodes running v1.10.x. Clusters in such a configuration could become unreachable or fail to run your workloads correctly. Additionally, security patches are not applied to v1.10.x and below.
We previously published a notice that Google would enable node auto-upgrade to node pools running v1.10.x or lower, to bring those clusters into a supported configuration and mitigate the incompatibility risk described above. To allow for sufficient time for customers to complete the upgrade themselves, Google postponed upgrading cluster control planes to 1.13 until mid-September 2019. Please plan your manual node upgrade to keep your clusters healthy and up to date.

Security bulletin
GKE v1.13.7.x includes patches that mitigate multiple vulnerabilities that are present in v1.13.6. Clusters running any v1.13.6.x version should upgrade to 1.13.7.x, to mitigate against these vulnerabilities, which are described in the following security bulletins:
New features
GKE usage metering (Beta) now supports tracking actual
consumption, in addition to resource requests, for clusters running
v1.12.8-gke.8 and higher, v1.13.6-gke.7 and higher, or 1.14.2-gke.8 and higher.
A new BigQuery table, gke_cluster_resource_consumption
, is
created automatically in the BigQuery dataset. For more information
about this and other improvements to Usage Metering, see
Usage metering (Beta).
Node auto-provisioning is supported on regional clusters running v1.12.x or higher.
July 29, 2019
VPC-native is no longer the default cluster network mode for new

Version updates
GKE cluster versions have been updated as detailed in the following sections. See these instructions to get a full list of the Kubernetes versions you can run on your GKE masters and nodes, and to review the Rollout schedule.
Important changes to clusters running unsupported versions
In addition to GKE's version policy, Kubernetes has a version skew policy of supporting only the three newest minor versions. Older versions are not guaranteed to receive bug fixes or security updates, and the control plane may become incompatible with nodes running unsupported versions.
For example, the Kubernetes v1.13.x control plane is not compatible with nodes running v1.10.x. Clusters in such a configuration could become unreachable or fail to run your workloads correctly. Additionally, security patches are not applied to v1.10.x and below.
To keep your clusters operational and to protect Google's infrastructure, we strongly recommend that you upgrade existing nodes to v1.11.x or higher before the end of June 2019. At that time, Google will enable node auto-upgrade on node pools older than v1.11.x, and these nodes will be updated to v1.11.x so that the control plane can be upgraded to v1.13.x and remain compatible with existing node pools.
We strongly recommend leaving node auto-upgrade enabled.
NOTE: As of 1.12 all kubelets are issued certificates from the cluster CA and verification of kubelet certificates is enabled automatically if all nodepools are 1.12+. We have observed that introducing older (pre 1.12) nodepools after certificate verification has started may cause connection problems for kubectl logs/exec/attach/portforward commands, and should be avoided.

We strongly recommend leaving node auto-upgrade enabled.
New default version
The default version for new clusters is now 1.12.7-gke.10 (previously 1.11.8-gke.6). If your cluster is using v1.12.6-gke.10, upgrade to this version to avoid a potential issue that causes auto-repairing nodes to fail.
Scheduled automatic upgrades
Masters and nodes with auto-upgrade enabled will be upgraded:
Current version | Upgrade version |
---|---|
All 1.10.x versions, including v1.10.12-gke.14 (continuing after unpausing node auto-upgrade) | v1.11.8-gke.6 |
v1.11.x versions older than v1.11.8-gke.6 | v1.11.8-gke.6 |
Rollouts are phased across multiple weeks, to ensure cluster and fleet stability.
New versions available for upgrades and new clusters
The following Kubernetes versions are now available for new clusters and for opt-in master upgrades and node upgrades for existing clusters.
v1.11.x
v1.11.9-gke.13
- Improvements to Vertical Pod Autoscaler
- Improvements to Cluster Autoscaler
- Cloud Run for GKE now uses the default Istio sidecar injection behavior
- Fix an issue that prevented the kubelet from seeing all GPUs available to nodes using the Ubuntu node image.
v1.12.x
v1.12.7-gke.17
- Upgrade Ingress controller to 1.5.2
- Improvements to Vertical Pod Autoscaler
- Improvements to Cluster Autoscaler
- Fix an issue that prevented the kubelet from seeing all GPUs available to nodes using the Ubuntu node image
- Fix an issue that sets the dynamic maximum volume count to 16 if your nodes use a custom machine type. The value is now set to 128.
v1.13.x
v1.13.5-gke.10
Upgrading to GKE v1.13.x
To prepare to upgrade your clusters, read the Kubernetes 1.13 release notes and the following information. You may need to modify your cluster before upgrading.
scheduler.alpha.kubernetes.io/critical-pod
is deprecated. To mark
Pods as critical, use
Pod priority and preemption.
node.status.volumes.attached.devicePath
is deprecated for Container
Storage Interface (CSI) volumes and will not be enabled in future
releases.
The built-in system:csi-external-provisioner
and
system:csi-external-attacher
Roles are no longer automatically created
You can create your own Roles and modify your Deployments to use them.
Support for CSI drivers using 0.3 and older versions of the CSI API is deprecated. Users should upgrade CSI drivers to use the 1.0 API during the deprecation period.
Kubernetes cannot distinguish between manually-provisioned zonal and regional persistent disks with the same name. Ensure that persistent disks have unique names across the Google Cloud project. This issue does not occur when using dynamically provisioned persistent disks.
If kubelet fails to register a CSI driver, it does not make a second attempt. To work around this issue, restart the CSI driver Pod.
After resizing a PersistentVolumeClaim (PVC), the PVC is sometimes left
with a spurious RESIZING
condition when expansion has already completed.
The condition is spurious as long as the PVC's reported size is correct.
If the value of pvc.spec.capacity['storage']
matches
pvc.status.capacity['storage']
, the condition is spurious and you can
delete or ignore it.
The CSI driver-registrar external
sidecar container v1.0.0 has a
known issue where it takes up to a minute to restart.
DaemonSets now use scheduling features that require kubelet version 1.11 or higher. Google will update kubelet to 1.11 before upgrading clusters to v1.13.x.
kubelet can no longer delete their Node API objects.
Use of the --node-labels
flag to set labels under the kubernetes.io/
and
k8s.io/
prefix will be subject to restriction by the NodeRestriction
admission plugin in future releases. See the
admission plugin documentation
for the list of allowed labels.
Rapid channel
1.14.1-gke.5
GKE v1.14.1-gke.5 (alpha) is now available for testing and validation in the Rapid release channel. For more details, refer to the release notes for Kubernetes v1.14.
GKE v1.14.x has the following differences from Kubernetes 1.14.x.
- GKE v1.14.x uses
kube-dns
rather thancore-dns
. - GKE v1.14.x does not support
Dramatically Simplify Kubernetes Cluster Creation,
a sub-feature of
kubeadm
. - GKE v1.14.x does not support taint-based eviction.
You cannot yet create an alpha cluster running GKE
v1.14.x. If you attempt to use the --enable-kubernetes-alpha
flag,
cluster creation fails.
Security bulletin
If you run untrusted code in your own multi-tenant services within Google Kubernetes Engine, we recommend that you disable Hyper-Threading to mitigate Microarchitectural Data Sampling (MDS) vulnerabilities announced by Intel. For more information, see the security bulletin.
New features
With GKE 1.13.5-gke.10, GKE 1.13 is now generally available for use in production. You can upgrade clusters running older v1.13.x versions manually.
GKE v1.13.x has the following differences from Kubernetes 1.13:
- GKE v1.13.x uses
kube-dns
rather thancore-dns
. - GKE v1.13.x does not support
Dramatically Simplify Kubernetes Cluster Creation,
a sub-feature of
kubeadm
. - GKE v1.13.x does not support taint-based eviction.
We are introducing Release channels, a new way to keep your GKE clusters up to date. The Rapid release channel is available, and includes v1.14.1-gke.5 (alpha). You can sign up to try release channels and preview GKE v1.14.x.
GKE Sandbox (Beta) is now available for clusters running v1.12.7-gke.17 and higher and v1.13.5-gke.15 and higher. You can use GKE Sandbox to isolate untrusted workloads in a sandbox to protect your nodes, other workloads, and cluster metadata from defective or malicious code.
Changes
For clusters running v1.12.x or higher and using nodes with less than 1 GB of memory, GKE reserves 255 MiB of memory. This is not a new change, but it was not previously noted. For more details about node resources, see Allocatable memory and CPU resources.
Rollout schedule
The rollout schedule is now included in Versioning and upgrades.
Coming soon
We expect the following changes in the coming weeks. This information is not a guarantee, but is provided to help you plan for upcoming changes.

with provisioning the ExternalIP on one or more Nodes causes the kubectl
command to fail. The following error is logged in the
kube-apiserver
log:
Failed to getAddresses: no preferred addresses found; known addresses
This issue is fixed in GKE 1.11.4-gke.8. If you can't upgrade to that version, you can work around this issue by following these steps:
-
Determine which Nodes have no ExternalIP set:
kubectl get nodes -o wide
Look for entries where the last column is
<none>
. - Restart affected nodes.
Known Issues
Users upgrading to GKE 1.11.3 on clusters that use Calico network policies
may experience failures due to a problem recreating the
BGPConfigurations.crd.projectcalico.org
resource. This problem does not
affect newly-created clusters. This is expected to be fixed in the coming
weeks.
To work around this problem, you can create the
BGPConfigurations.crd.projectcalico.org
resource manually:
- Copy the following script into a file named
bgp.yaml
:apiVersion: apiextensions.k8s.io/v1beta1 kind: CustomResourceDefinition metadata: name: bgpconfigurations.crd.projectcalico.org labels: kubernetes.io/cluster-service: "true" addonmanager.kubernetes.io/mode: Reconcile spec: scope: Cluster group: crd.projectcalico.org version: v1 names: kind: BGPConfiguration plural: bgpconfigurations singular: bgpconfiguration
- Apply the change to the affected cluster using the following command:
kubectl apply -f bgp.yaml
Users modifying or upgrading existing GKE 1.11.x clusters that use Alias IP may experience network failures due to a mismatch between the new IP range assigned the Pods and the alias IP address range for the nodes. This is expected to be fixed in the coming weeks.
To work around this problem, follow these steps. Use the name of your node
in place of
, and use your cluster's
zone in place of
.
- Cordon node that has been affected:
kubectl cordon
[NODE_NAME] - Drain node of all workloads:
kubectl drain
[NODE_NAME] - Delete the Node object from Kubernetes
kubectl delete nodes
[NODE_NAME] - Reboot the Node. This is not optional.
gcloud compute instances reset --zone

GKE 1.11.2-gke.9 is now generally available.
You can now select Container-Optimized OS with
containerd
images when creating, modifying, or upgrading a cluster to GKE v1.11. Visit Using Container-Optimized OS with containerd for details.The CustomResourceDefinition API supports a
versions
list field (and deprecates the previous singularversion
field) that you can use to support multiple versions of custom resources you have developed, to indicate the stability of a given custom resource. All versions must currently use the same schema, so if you need to add a field, you must add it to all versions. Currently, versions only indicate the stability of your custom resource, and do not allow for any difference in functionality among versions. For more information, visit Versions of CustomResourceDefinitions.Kubernetes 1.11 introduces beta support for increasing the size of an existing PersistentVolume. To increase the size of a PersistentVolume, edit the PersistentVolumeClaim (PVC) object. Kubernetes expands the file system automatically.
Kubernetes 1.11 also includes alpha support for expanding an online PersistentVolume (one which is in use by a running deployment). To test this feature, use an alpha cluster.
Shrinking persistent volumes is not supported. For more details, visit Resizing a volume containing a file system.
Subresources allow you to add capabilities to custom resources. You can enable
/status
and/scale
REST endpoints for a given custom resource. You can access these endpoints to view or modify the behavior of the custom resource, usingPUT
,POST
, orPATCH
requests. Visit Subresources for details.
Also, 1.10.9-gke.0 is available.

May 1, 2018
Known Issues
In Kubernetes versions 1.9.7, 1.10.0, and 1.10.2, if an NVIDIA GPU
device plugin restarts but the associated kubelet does not, then the node
allocatable for the GPU resource nvidia.com/gpu
stays zero
until the kubelet restarts. This prevents new pods from consuming GPU
devices.
The most likely scenario when this problem occurs is after a cluster is created or upgraded with Kubernetes 1.9.7, 1.10.0, or 1.10.2 and the cluster master is upgraded to a new version, which triggers an NVIDIA GPU device plugin DaemonSet upgrade. The DaemonSet upgrade causes the NVIDIA GPU device plugin to restart itself.
If you use the GPU feature, do not create or upgrade your cluster with Kubernetes 1.9.7, 1.10.0, or 1.10.2. This issue will be addressed in an upcoming release.

March 19, 2018
Fixed
Kubernetes 1.9.4+: Fixes a bug that prevented clusters with IP aliases from appearing.
March 13, 2018
Fixed
A patch for Kubernetes vulnerabilities CVE-2017-1002101 and CVE-2017-1002102 is now available according to this week's rollout schedule. We recommend that you manually upgrade your nodes as soon as the patch becomes available in your cluster's zone.
Issues
Breaking Change: Do not upgrade your cluster if your application requires mounting a secret, configMap, downwardAPI, or projected volume with write access.
To fix security vulnerability CVE-2017-1002102, Kubernetes 1.9.4-gke.1, Kubernetes 1.8.9-gke.1, and Kubernetes 1.7.14-gke.1 changed secret, configMap, downwardAPI, and projected volumes to mount read-only, instead of allowing applications to write data and then reverting it automatically. We recommend that you modify your application to accommodate these changes before you upgrade your cluster.
If your cluster uses IP Aliases
and was created with the --enable-ip-alias
flag, upgrading the
master to Kubernetes 1.9.4-gke.1 will prevent it from starting properly.
This issue will be addressed in an upcoming release.
