Upstream Kubernetes v1.27 and v1.28 on VMware vSphere¶
Our recent release update to our Preview environment adds support for a number of new features and enhancements. We will write about these in separate blogs. This blog is focused on support for lifecycle management of upstream Kubernetes v1.27 and v1.28 on VMware vSphere
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 Management Platform has been validated on this Kubernetes version. This will be promoted from Preview to Production in a few days and will be made available to all customers.
New Cluster Provisioning¶
Users of the Rafay platform can provision new clusters based on Kubernetes v1.27 and v1.28 using the supported interfaces. Shown below is a screenshot
Once a new VMware v1.27 and v1.28 clusters are provisioned, administrators can click on the nodepools tab to check the node pool version. In the example shown below, notice that the version and ova template shows that the attached node is based on Kubernetes v1.27 and 1.28.
Clicking on a node in the cluster dashboard will show detailed information about the Kubernetes version for both worker nodes and the control plane
In-Place Upgrades¶
Users of the Rafay platform with existing clusters can upgrade their clusters to Kubernetes v1.27 or v1.28. Remember that upgrades 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 activity tab. An illustrative example is shown below.
