Expanded coverage for compute flexible committed use discounts (CUDs) is available to all Cloud Billing accounts. All Cloud Billing accounts have been automatically migrated to the new spend-based CUD model and you no longer need to opt in to benefit from the expanded coverage. For the full list of eligible SKUs across Compute Engine, GKE, and Cloud Run, see SKU Groups - Compute Flexible CUD Eligible SKUs.

To learn more about compute flexible CUDs and how they apply to your GKE usage, see the GKE CUDs documentation.

Issue

In some GKE versions earlier than 1.34.0-gke.2011000, using the Cloud Storage FUSE CSI driver with streaming writes enabled might cause file writes to fail with an Input/Output error on the application side accompanied by 503 errors in the gke-gcsfuse-sidecar logs. This issue occurs when streaming writes are enabled, and is caused by stalls during write operations. Streaming writes are enabled by default in GKE versions 1.33.2-gke.4655000 and later.

To work around this limitation, you can perform one of the following actions:

Upgrade your cluster to GKE version 1.34.1-gke.3849001 or later.
If you can't upgrade your cluster, disable streaming writes by passing the --enable-streaming-writes=false or write:enable-streaming-writes:false flags when you configure mount options for Cloud Storage FUSE CSI driver. These flags only prevent error reliably when staging writes use fast media types such as SSD or tmpfs. tmpfs is specified using --temp-dir or file-system:temp-dir flags when you configure mount options.

For more details, including instructions on how to confirm if you're affected by this, see Pods unable to run on a Node due to NRI RunPodSandbox failed.

The fix is available with GKE version 1.34.1-gke.3899000 and later.

Announcement

Kubernetes 1.35 is now available in the Rapid channel

Kubernetes 1.35 is now available in the Rapid channel. For more information about the content of Kubernetes 1.35, read the Kubernetes 1.35 Release Notes and Kubernetes 1.35 Release Blog.

Deprecated

Deprecated in 1.35

The PreferClose value for a Kubernetes Service's trafficDistribution field is now deprecated in favor of the more explicit PreferSameZone.

Removed in 1.35

Kubernetes has deprecated cgroup v1 support.
GKE is removing cgroup v1 support in 1.35. If you have specifically configured your node pools to use cgroup v1 then upgrades will be blocked until you configure cgroup v2. To migrate to cgroup v2, see Migrate to cgroup v2.

Change

Other changes in 1.35

Windows containerd 2.1: GKE Windows nodes will use containerd 2.1 in 1.35, upgraded from containerd 1.7 in GKE 1.34. Clusters containing Windows nodes will have auto-upgrades to 1.35 delayed until 1.34 EOL due to possible compatibility issues introduced in containerd 2.0. Check if you're using deprecated containerd features removed in 2.0 and migrate off of them, see Migrate nodes to containerd 2. After all deprecated features are removed, manually upgrade your cluster to 1.35.

Change

GKE Standard clusters enrolled in the Regular channel now support Autopilot features. Autopilot features include the container-optimized compute platform and fully managed nodes, letting you use Autopilot's advantages without migrating to a dedicated Autopilot cluster.

To use Autopilot features in Standard clusters, use either of the following configurations:

Enroll a cluster in the Regular channel with GKE version 1.34.1-gke.1829001 or later.
Enroll a cluster in the Rapid channel with GKE version 1.33.1-gke.1107000 or later.

For more information, see Run workloads in Autopilot mode in Standard clusters.

Issue

In rare cases, a cluster control plane upgrade can cause an Autopilot node to enter into a state in which new system and user Pods are unable to run, which then causes issues such as broken Pod networking. GKE is regularly detecting this issue, and when possible GKE is mitigating new occurrences of this issue. For more details, see Pods unable to run on a Node due to NRI RunPodSandbox failed, and to mitigate this issue yourself, follow the procedure in the section Consistently unreliable workload performance on a specific node.

Issue

Starting with version 1.33.2-gke.4655000, the GCSFuse CSI Driver automatically applies performance-tuning defaults for Cloud Storage FUSE volumes used on nodes with high-performance machine types. However, in GKE versions 1.34.1-gke.1431000 to 1.34.1-gke.3403001, these defaults are not being applied. This is due to an issue where GCSFuse fails to recognize the machine type from the configuration file provided by the GCSFuse CSI Driver.

To apply the performance defaults, explicitly set the machine-type as a gcsfuse mount option. Use the command-line flag format, with the key and value separated by an equals sign (=).

For example: machine-type=n2-standard-4

Ensure the Pod using the GCSFuse volume is scheduled on a node that matches the specified machine type. These settings are optimized for high-performance machine types and might not be suitable for other node types. For more information on scheduling, see the Kubernetes documentation on assigning Pods to Nodes.

Issue

In GKE versions 1.34.1-gke.2037001 and 1.34.1-gke.2541000, Arm nodes that use an Ubuntu node image might incorrectly use an image with a 64 KB page size instead of the default 4 KB page size. Avoid using version 1.34.1-gke.2037001 and 1.34.1-gke.2541000 for your Ubuntu Arm nodes.

Issue

GKE versions earlier than 1.32 don't support direct NFS volume mounts to NFS volumes that exclusively use an NFS protocol greater than NFSv4.0.

When using direct NFS volume mounts, Pods on GKE node versions earlier than 1.32 might fail to mount NFS volumes that are configured to only support protocols greater than NFSv4.0 (such as NFSv4.1 or NFSv4.2). This issue occurs because the containerized_mounter on these earlier GKE versions uses version 1.2.8 of the nfs-utils package, which doesn't support NFSv4 minor versions. As a result, the mount process fails with the mount.nfs: access denied by server error message.

This issue doesn't affect GKE version 1.32 and later, which include an updated version of the nfs-utils package. To resolve this issue, try one of the following options:

Upgrade clusters to GKE version 1.32 or later.
Configure the NFS volume to support both the NFSv3 and NFSv4 protocols, which allows the mount to succeed by falling back to a compatible version.
Use a PersistentVolume and PersistentVolumeClaim to mount the NFS volume, which allows for explicit NFS version specification.
