 # krane restart

+`krane restart` is a tool for restarting all of the pods in one or more deployments, statefuls sets, and/or daemon sets. It triggers the restart by patching template metadata with the `kubectl.kubernetes.io/restartedAt` annotation (with the value being an RFC 3339 representation of the current time). Note this is the manner in which `kubectl rollout restart` itself triggers restarts.
