version

The Kubernetes version to update to. If no version is specified, then the node group will be updated to match the cluster's current Kubernetes version, and the latest available AMI for that version will be used. You can also specify the Kubernetes version of the cluster to update the node group to the latest AMI version of the cluster's Kubernetes version. If you specify launchTemplate, and your launch template uses a custom AMI, then don't specify version, or the node group update will fail. For more information about using launch templates with Amazon EKS, see Customizing managed nodes with launch templates in the Amazon EKS User Guide.
