In order to take advantage of all of these options, Rancher will create and manage a launch template for you. Each cluster in Rancher will have one Rancher-managed launch template and each managed node group that does not have a specified launch template will have one version of the managed launch template. The name of this launch template will have the prefix "rancher-managed-lt-" followed by the display name of the cluster. In addition, the Rancher-managed launch template will be tagged with the key "rancher-managed-template" and value "do-not-modify-or-delete" to help identify it as Rancher-managed. It is important that this launch template and its versions not be modified, deleted, or used with any other clusters or managed node groups. Doing so could result in your node groups being "degraded" and needing to be destroyed and recreated.
