Kubernetes v1.26 for Rafay MKS¶
Our recent release update in May 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 Kubernetes v1.26 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. 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 v1.26 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 v1.26. 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.
Kubernetes v1.26 clusters provisioned and managed by Rafay are CNCF conformant. Conformance ensures that Rafay's support for Upstream Kubernetes supports the required APIs, as do open source community versions.
