Kubernetes v1.28 for Rafay MKS¶
Our recent release update adds support for a number of new features and enhancements. This blog is focused on support for Kubernetes v1.28 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.
New Cluster Provisioning¶
Users of the Rafay platform can provision new clusters based on Kubernetes v1.27 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.
Users of the Rafay platform with existing clusters based on Upstream Kubernetes (Rafay MKS) will be prompted to upgrade their clusters to Kubernetes v1.28. 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. You can see an illustrative example below. The platform maintains a history of all successful and failed upgrades for compliance and governance purposes.
Clicking on any item providers the administrator with extensive details about what happened during the in-place upgrade process. See example below.
