A team wants to adopt Argo Rollouts without moving the pod template out of their existing Deployment manifests. Which field supports this?

選択肢

1. A template field on the Rollout that names the Deployment, so that the controller copies the pod template out of it once and then keeps its own copy in the Rollout specification.
2. An ownerReference from the Deployment to the Rollout that consumes its template.
3. workloadRef, which points at the workload that provides the pod template.
4. The restartAt field, which the controller reads from the existing Deployment manifest.
