A team wants a human to approve a blue-green release before production traffic moves. Which setting achieves this?

選択肢

1. Set autoPromotionEnabled to false, because it is true by default.
2. Set the Rollout paused field to true permanently.
3. Add an empty pause step, because blueGreen supports the same steps list as canary.
4. Set autoPromotionSeconds to zero, which tells the controller to wait forever for an explicit promotion instead of counting down to an automatic one.
