Kubernetes v1.27 for Rafay MKS¶

Our recent release update in June adds support for a number of new features and enhancements. This blog is focused on support for Kubernetes v1.27 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, this version also deprecates and removes a number of features. To ensure there is zero impact to our customers, we have made sure that every feature in the Rafay Kubernetes Operations Platform has been validated on this Kubernetes version.

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

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 v1.27. 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.
