Hi, @Haoyu Zha! Welcome to the community!
Currently, it’s not possible to configure the wait timeout for aws-ecs-deploy. In this case, I went ahead and created a feature request to add this option, as you can see here:
I would suggest that you add your vote there (by selecting the Vote for this issue link) as the number of votes helps the development team and product managers better understand the demand for new features.
You are more than welcome to leave any feedback, and you can also add yourself as a watcher (by selecting the Start watching this issue link) if you'd like to get notified via email on updates.
Implementation of new features is done as per our policy here and any updates will be posted in the feature request.
Please, feel free to share any additional questions or concerns regarding this case.
