Support for Kubernetes version 1.35.2

OCI Kubernetes Engine (OKE) now supports Kubernetes version 1.35.2, in addition to versions 1.34.2 and 1.33.1. With the availability of support for Kubernetes version 1.35.2, OKE will cease support for Kubernetes version 1.32.10 on May 28, 2026. Oracle strongly recommends you immediately upgrade clusters to Kubernetes version 1.33.1, 1.34.2, or 1.35.2. For more information about Kubernetes version 1.35.2, see the Kubernetes Changelog.

Note the following:

• Although Kubernetes version 1.32.10 will not be supported after May 28, 2026, it might continue to be available for selection. However, Oracle strongly recommends you upgrade clusters to Kubernetes version 1.33.1, 1.34.2, or 1.35.2.

• For worker nodes in clusters running Kubernetes version 1.35 (and later), Kubernetes Engine supports OKE OL8 images, and custom images based on OKE OL8 images. Custom images based on OL8 platform images are also supported, but only if you enable cgroups v2 (see Enabling Cgroups v2 on OL8 Worker Nodes Using Custom Images).

  Platform images (both OL7 platform images and OL8 platform images) are not supported. Custom images based on OKE OL7 images, or on OL7 platform images, are not supported. Attempts to use these images on clusters running Kubernetes version 1.35 (and later) will result in errors.

  For more information, see Notes about Kubernetes version 1.35 (and later) and Support for OKE Images, Platform Images, and Custom Images.

To upgrade a cluster to a new Kubernetes minor version:

1. Upgrade the Kubernetes version running on the control plane by following the instructions in Upgrading the Kubernetes Version on Control Plane Nodes in a Cluster.
2. Having upgraded the control plane, upgrade the Kubernetes version running on worker nodes in a node pool by following the instructions in Upgrading the Kubernetes Version on Worker Nodes in a Cluster.

Note:

Always follow the Kubernetes skew policy for Kubernetes minor version support. Note that in Kubernetes version 1.28, the Kubernetes skew policy expanded. Prior to Kubernetes version 1.28, the skew policy required a cluster's control plane nodes to be no more than two versions ahead of worker nodes. From Kubernetes version 1.28, the Kubernetes skew policy allows control plane nodes to be up to three versions ahead of worker nodes.

Example skew policy:

• Kubernetes control plane nodes are at version 1.35.2
• Kubernetes worker nodes must be at version 1.35.2, 1.34.2, 1.33.1, or 1.32.10

Note that although the worker nodes in a node pool must follow the Kubernetes skew policy, you do not have to upgrade them one minor version at a time.
