To mitigate upgrade risks, Amazon Elastic Kubernetes Service (EKS) began supporting rollback to the previous minor Kubernetes version within seven days of an upgrade. This feature allows users to validate new versions under production workloads and revert if issues arise, enhancing upgrade confidence.
Rollback initiation is available via console, CLI, or SDKs, preceded by automated readiness checks assessing API compatibility, version skew, add-ons, and cluster health. For clusters with EKS Auto Mode enabled, rollback sequence respects disruption controls by managing worker nodes before the control plane. No extra cost applies, and the feature is available globally where EKS operates.
