Reduce the Kubernetes Upgrade Process to a Single Click
It is critical to have a reliable, repeatable, and efficient cluster upgrade process to ensure both the Kubernetes version for the cluster and the OS for the nodes are kept current. However, upgrading a fleet of Kubernetes clusters often ends up being a multi-day task with various cluster components being upgraded manually. This manual process is burdensome, error prone and time consuming. With Rafay KMC, administrators gain seamless, in-place, 1-click upgrade workflows for both Amazon EKS & upstream K8s environments. With Rafay’s 1-Click K8s Upgrades, you can automatically:
Perform pre-flight checks to detect and report any known issues that may cause problems with the upgrade process
Upgrade the Amazon EKS/Upstream K8s control plane, worker node groups, and critical cluster add-ons (core-dns, kube-proxy and aws-node) in a controlled, phased manner
Perform post-upgrade validation checks to ensure the upgrade went smoothly
Access to a complete audit trail and detailed upgrade history to demonstrate upgrade success/failure
Cluster Upgrade Alerts & Notifications
Administrators are shown a notification when an upgrade is available for a cluster. Clicking on the notification will provide the administrator with additional information on what is available. A red banner indicates you are multiple versions behind the latest version and a blue banner indicates that the cluster is one version behind the latest version.
1-Click Cluster Upgrades
When selected (or automatically initiated), Rafay will upgrade all components to the new version of Kubernetes including the EKS Control Plane, all Node Groups (both managed and self-managed) and critical cluster add-ons. AMI upgrades also follow the same process as Kubernetes upgrades.

Preflight Checks and Post-Upgrade Validation
Preflight checks are automatically performed before the cluster is upgraded to the new Kubernetes version. The following preflight checks are performed and have to pass before the upgrade process is allowed to proceed: cluster readiness, control plane health, and health of critical pods. Post upgrade validation checks are also performed to ensure nodes are ready and pods are running.
Kubernetes Upgrade History & Audit Trail
Rafay automatically maintains a history of all successful and unsuccessful upgrades. Further, an audit entry is generated when a Kubernetes upgrade is performed to maintain a log of who performed the upgrade when and from which version to which version of Kubernetes.
