Kubernetes v1.32 for Rafay MKS

As part of our January release, alongside other enhancements and features, we are adding support for Kubernetes v1.32 with Rafay MKS (i.e., upstream Kubernetes for bare metal and VM-based environments).

Both new cluster provisioning and in-place upgrades of existing clusters are supported. As with most Kubernetes releases, v1.32 deprecates and removes several features. To ensure zero impact to our customers, we have validated every feature of the Rafay Kubernetes Operations Platform on this Kubernetes version.

Kubernetes v1.32 Release

New Cluster Provisioning

Users of the Rafay platform can provision new clusters based on Kubernetes v1.32 using the supported interfaces. Shown below is a screenshot

Clicking on a node in the cluster dashboard will provide additional details about the Kubernetes version as well.

Prerequisites for RHEL ⅞-based new Clusters with Kubernetes v1.32

When creating new clusters with RHEL nodes and Kubernetes v1.32, ensure the following kernel versions are met:

  • For machines using cgroup v1: Kernel version must be >= 4.19.

Recommendation: As cgroup v1 support is now in maintenance mode, it is strongly recommended to migrate to cgroup v2 for future compatibility.

These prerequisites apply specifically to new cluster creation. Note that cluster upgrades have been validated and are working without issues.

You can check the cgroup version on the machines by following the instructions in the Kubernetes documentation.

In-Place Upgrades

Users of the Rafay platform with existing clusters based on Upstream Kubernetes (Rafay MKS) will be prompted to upgrade their clusters to Kubernetes v1.32. Remember that upgrades for Rafay MKS are performed "in-place" and are "non disruptive" to running applications. All upgrade operations are audited in the centralized audit logs. Users can also view upgrade history by clicking on the upgrades tab. An illustrative example is shown below.

CNCF Conformance

Kubernetes v1.32 clusters provisioned and managed by Rafay are CNCF conformant. We have submitted the CNCF conformance results for v1.32, meeting all CNCF requirements as we do for every release. Conformance ensures that Rafay's support for Upstream Kubernetes adheres to the required APIs, maintaining compatibility with open source community versions.
